Description

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

Conventional configuration and its problems In conventional stationary vacuum cleaners of this type, 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. was connected to. However, with this configuration, when attaching or detaching the dust collection case, the case must be held while operating the buckle, which requires a lot of effort 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.

Configuration of the Invention The stationary vacuum cleaner of the present invention includes a built-in fan motor,
and a dust collection case which is movably supported with respect to the support leg, and whose rear side is positioned by contacting the reinforcing bar of the support leg, and which is detachably connected to the lower part of the main body,
The support leg has a lever function on the front and back, and the fulcrum of the main lever and one end of the sub-lever are located in front of the main body, and the point of action of the main lever and the sub-lever are located on the front and back of the main body. The reinforcing bar is provided at a position where it comes into 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.

Therefore, by lifting the main body, the dust collection case can be easily attached and detached, 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 flowing in from the suction port 2 of the dust collection case 1 is filtered by a filter installed inside the case, and only the acclimatized air passes through the fan motor in the main body 3 and is discharged from the exhaust port 4. The structure is such that the dust is 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. In order to prevent the dust collecting case 1 from being attached, a protective body ζ9 made of rubber or the like provided on the reinforcing bar 7 is a handle for transporting the dust collecting case 1.

The main body 3 is supported on support legs 5 so as to be able to move up and down,
The dust collecting 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. Although the above-mentioned support mechanism is provided on both sides of the main body 30, 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 6; 11
is a flat part formed on the side of the main body 3 facing the metal fitting 1o; 12 is a main lever that exerts a lever function;
They are respectively pivotally supported by the plane portions 11 of the main body 3 via the base ends thereof, and further, the base ends are located at the front side of the main body 3.

That is, the main lever 12 exhibits a lever function using the pivot point of the shaft 13 to the metal fitting 10 as a fulcrum, the pivot point of the shaft 14 to the main body 3 as a point of action, and the base end as a point of force.

Reference numeral 16 denotes another sub-lever located behind the main lever 12, and both ends thereof are connected to the vertical piece of the metal fitting 10 and the flat part 11 of the main body 3 via shafts 16 and 1, respectively. , 11.

In the configuration of 10, if an external force is applied to the base end of the main lever 120 in the L direction, the main lever 120 rotates clockwise around the shaft 13, and along with this rotation, the main lever 3 The front of
-I can get it. Since the width lever 16 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 Fig. 6.6).

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 removed and installed. 1, by rotating the main lever 12 in the opposite direction to the above, the main body 3 and the dust collection case 1 are coupled together. In addition, in this embodiment, the shaft 1 of the main lever 12
The shaft support spacing according to 3.14 is the shaft 16.17 of the secondary lever 16.
The shaft support spacing is also set large, and for that reason,
The main body 3 moves upward in the forward upward state.

Now, when the main lever 12 starts rotating clockwise,
The load of the main body 3 is applied to the secondary lever 16, and a counterclockwise force is temporarily activated. When the sub lever 16 operates in the counterclockwise direction, it comes into pressure contact with the rear part 75 of the main body 3 (dust collection case 1), which makes the operation of the main lever 12 heavier.However, in the above embodiment, Taking advantage of the fact that the main body 3 is displaced not only upwardly but also backwards as the main lever 12 rotates clockwise, the rear lower surface of the main body 3 is caught by the reinforcing bar 7 at the beginning of the operation. be.

When a clockwise rotational force is applied to the secondary lever 16, the rear of the main body 3 is also displaced upward as the secondary lever 16 rotates.

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, which is very convenient when disposing of garbage.

Furthermore, the main body can be lifted smoothly and with little effort using the main lever, which provides excellent effects.
