Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a so-called stationary electric vacuum cleaner, in which the main body is left stationary like a central vacuum cleaner.

Conventional configuration and its problems Conventionally, in the case of this type of stationary vacuum cleaner, the main body with a built-in fan motor etc. is fixed to a support leg, and the dust collection case is suspended from the bottom of the main body via a buckle. It was connected. However, with this configuration, when attaching or detaching the dust collecting case, the buckle must be operated while holding the dust collecting case, which requires a great deal of labor and is not easy to use.

OBJECTS OF THE INVENTION The present invention solves these conventional drawbacks and provides a stationary vacuum cleaner whose dust collection case can be easily attached and detached.

Composition of the Invention The stationary vacuum cleaner of the present invention includes a main body that includes a built-in fan motor and is movably supported on a support leg, and a main body that is positioned by abutting the reinforcing bar of the support leg with its rear side. It is equipped with a dust collection case that is detachably connected to the lower part, has a lever function on the front and back of the support leg, and has a fulcrum of the main lever and one end of the sub-lever, with the point of effort located at the front side of the main body. The point of action of the main lever and the other end of the auxiliary lever are respectively pivotally supported at the front and rear of the main body, and the reinforcing bar is in contact with the rear lower surface of the main body at least at the beginning of the separation movement of the main body from the dust collection case. It is placed in a position where they are in contact with each other.

Therefore, the dust collection case can be easily attached and detached by lifting the main body, and the main body can be lifted with little effort by the lever mechanism.

Description of examples Examples thereof will be described below with reference to the accompanying drawings.

In the figure, dust-containing air that flows in from the suction port 2 of the dust collection case 1 is passed through a filter installed inside the case, and only purified air passes through the fan motor in the main body 3 and is discharged from the exhaust port 4. is configured to be collected in the dust collection case 1. The dust collection case 1 is placed on the bottom plate 6 of the support leg 5, and is positioned by a reinforcing bar 7 provided above and laterally on the support leg 5. 8 is a protective member such as rubber provided on the reinforcing bar 7 to prevent damage to the dust collecting case 1, and 9 is a handle for transporting the dust collecting case 1.

The main body 3 is supported so as to be movable up and down relative to the supporting legs 5, and the dust collection case 1 can be attached and detached during this upward movement.

Next, the structure of the movable support mechanism of the main body 3 with respect to the support leg 5 will be explained. The above support mechanism is based on the main body 3.
Although they are provided on both sides, the explanation will be given for only one side.

10 is an L-shaped metal fitting fixed to the upper horizontal part of the support leg 5; 11 is a flat part formed on the side of the main body 3 facing this metal fitting 10; 12 is a main lever that exerts a lever function; It is pivotally supported via a shaft 13 to a vertical piece of the metal fitting 10 and midway to a flat part 11 of the main body 3 via a shaft 14, and furthermore, the base end is located at the front side of the main body 3. It is something.
That is, the main lever 12 is connected to the metal fitting 1 by the shaft 13.
0 as a fulcrum, the shaft 14 to the main body 3 as a point of action, and the proximal end as a point of force to exert a lever function.

Reference numeral 15 designates another sub-lever located behind the main lever 12, and both ends thereof are supported by the vertical piece of the metal fitting 10 and the flat part 11 of the main body 3 via shafts 16 and 17, respectively.

In the above configuration, if an upward external force is applied to the base end of the main lever 12, the lever 12 will move toward the shaft 1.
3 as a fulcrum, and as the main body 3 rotates clockwise, the front of the main body 3 is lifted. Since the width lever 15 also rotates in response to the upward movement of the main body 3, the rear of the main body 3 is similarly lifted upward (see FIGS. 5 and 6).

Therefore, since the main body 3 and the dust collection case 1 are separated from each other at this point, the dust collection case 1 can be easily taken out and installed. Further, by rotating the main lever 12 in the opposite direction to the above, the main body 3 and the dust collection case 1 can be connected. In this embodiment, the spacing between the shafts 13 and 14 of the main lever 12 is set to be larger than the spacing between the shafts 16 and 17 of the sub-lever 15, so that the main body 3 is Moves upward in the upward state.

Now, when the main lever 12 starts rotating clockwise, the load of the main body 3 is applied to the sub lever 15, and a counterclockwise force is temporarily activated. Secondary lever 1
When the main lever 5 operates counterclockwise, the rear of the main body 3 comes into pressure contact with the dust collection case 1, and the operation of the main lever 12 becomes heavier. However, in the embodiment described above, the main body 3 is displaced not only upward but also backward as the main lever 12 rotates in the clockwise direction. I tried to accept it.

As a result of the above, the main body 3 is initially displaced in a forward upward position using the contact portion with the reinforcing bar 7 as a fulcrum (FIG. 7), and then, when a clockwise rotational force is applied to the auxiliary lever 15, As the sub-lever 15 rotates, the rear of the main body 3 is also displaced upward.

Therefore, the operation of the main lever 12 becomes smooth and labor can be reduced.

Effects of the Invention As described above, according to the present invention, by lifting the main body, it becomes easier to take out and attach the dust collection case.
It is very convenient when disposing of garbage.

Furthermore, the main body can be lifted up smoothly using the main lever, and with little effort, resulting in excellent effects.
