Abstract

PURPOSE:To save the space by containing the greater part of motor in the hub section of blade while containing a swing device arranged at the lower section of a protection net within the thickness thereof then arranging them inclinably on a base. CONSTITUTION:A blade 3 has a hub section and covers the outer circumference of a motor 1. A swing device 5 containing a small motor and a link mechanism is fixed to the lower end of a protection net 4 where a receiving member 7 is pivoted inclinably to a base 8 secured through a fixing metal 9 to the wall 10. Consequently, when it is not used, projection from the wall face is reduced considerably thereby the fault is prevented and the space is saved.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a wall fan that is used by being hung on a wall.

2. Prior Art Conventionally, this type of wall-mounted electric fan has had a configuration as shown in FIG. In other words, the approximately L-shaped base 37 is connected to the wall 4.
1 with a mounting bracket 42, a bracket 36 is rotatably attached to the tip of a horizontal piece projecting forward of the base 37 with an elevation shaft 38, and the electric motor 31 is mounted on the bracket 36 with a core frame 37. It is pivoted so that it can swing freely. In addition, 33 in the figure is a blade attached to the rotating shaft 32 of the electric motor 31, 39 is a protection net, and 34
36 is a connecting rod, and 40 is a jacket.

In the above configuration, when the electric motor 31 is energized, the rotating shaft 32
The blade 33 connected to rotates and blows air.

The range of this air blowing is determined by swinging the swing device 34 to the left and right, and manually within the range of the elevation angle a.
It is possible to adjust the wind direction up and down. Also, the minimum protrusion distance from the wall at this time was at the maximum depression angle shown in the figure.

Problems to be Solved by the Invention In such a conventional configuration, the projecting distance from the wall surface is long, occupying space on the wall surface especially when not in use, and in extreme cases, when a person stands up , there was a problem that accidents such as being hit on the head were likely to occur. In addition, in many cases, people spend the winter with the device attached to the wall because there is no storage space, etc. In this case, in addition to the above-mentioned inconvenience, the protrusion from the wall increases the occupied space, causing the indoor living space to increase. The problem was that it was being narrowed down.

The present invention solves these problems, and provides a wall-mounted fan that greatly reduces the protruding distance from the wall surface, prevents the aforementioned accidents, and also saves space and makes effective use of indoor space. The purpose is to provide

Means for Solving the Problems In order to solve this problem, the present invention has a method in which most of the electric motor is housed in the hub of the blade, the swinging device provided at the bottom of the protective net is housed within the thickness range of the protective net, and , these are installed on a base so that they can be tilted downwards.

Function: With this configuration, when blowing air, the left and right head can vibrate and tilt freely as before.Moreover, the electric motor that protrudes from the rear of the protective net is housed in the impeller, and the rotation axis necessary for the swing movement Since the two swinging devices are provided within the thickness range of the protective net, the protrusion distance from the wall surface is shortened.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2. In the figure, the electric motor 1 has a disk shape with a length shorter than its outer diameter, and the blades 3 directly connected to the rotating shaft 2 have a cylindrical hub part, and the electric motor
Therefore, the distance between the rear end of the electric motor 1 and the front end of the blade 3 is shortened. Note that 2 is a fixed member. The electric motor 2 and the blades 3 are surrounded by a protective net 4, and the electric motor 1 is held with its back surface fixed to the center of the protective net 4. A swinging device 6 containing a small motor and a link mechanism is attached to the lower end of the protection net 4, and this swinging device 6 is supported by a rotating shaft 6 on a lower receiving member 7. The receiving member 7 is pivotally connected to the base 8 so as to be freely tiltable and vertical;
The base 8 is attached to the wall 1o with a mounting bracket 9. The swinging device 6 and the receiving member 7 have external shapes that fall within the thickness range of the protective net 4.

In the wall-mounted electric fan having the above configuration, first, the electric motor 1 and the blades 3 are manually set within the range of the elevation angle A, and then the electric motor 1 and the blades 3 are set manually.
The blade 2 is oscillated from side to side by the oscillating device 6 while the air blowing operation is performed. The majority of the motor 1 is the blade 3.
The fan section consisting of the electric motor 1 and the blades 3 is configured to be thin overall, and the neck camera 6 and the rotating shaft 6 are placed within the thickness range of the protective net 4. Therefore, in the stored state as shown in FIG. 1, the overall protruding length is smaller than the wall 10, so that it does not occupy a large amount of room space and the fan section does not get in the way.

Effects of the Invention As is clear from the description of the embodiments above, according to the present invention, the same air blowing range as before can be maintained, and when not in use, the protrusion from the wall is greatly reduced, which helps prevent accidents. Aim for it,
This has the effect of increasing safety, saving space, and greatly increasing the added value of the product.
