Description

[Detailed description of the invention] Electric vacuum cleaners rotate an impeller directly connected to a motor provided inside the casing at high speed to generate air suction force inside the casing, and the suction action causes the air to be extended outside the casing. The dust is sucked into the dust collection bag through the suction hose
The air filtered by the dust bag is passed through an impeller and discharged to the outside.

The present invention differs from the conventional electric cleaning method in this suction method pressure.
The structure is basically the same as the "conventional structure", but the air is discharged at a constant pressure to the outside of the casing, and the air is sucked and guided to the periphery to locally blow up and suck dust. It is aimed at effectiveness.

The following is a theory 8A based on the embodiments of the drawings. 1i (7) having filterability in front of it.
), a suction hose (91 is connected to the suction base pipe (81), and a suction tube (81 is protruded outside the casing (1)) connected to the collection J1 unit (71). This is no different from the conventional machine.In the present invention, in addition to the constituent pressure, a return passage (10) for air guided to the rear of the impeller (51 and motor (61) is formed in the casing (1 circle). ) and return the hose (12) to the outlet base pipe (11).
) are connected so that the spout (12a) at the tip thereof faces the periphery of the suction port (9a) of the suction hose (9). Furthermore, an exhaust air regulating valve (13) is provided at the rear of the casing (11) in place of the exhaust hole of the conventional machine.

Among the above, the suction hose (91) and return hose (12) are
As shown in the figure, place the tip of the mouthpiece (9
From the standpoint of use, it is desirable to configure a) and the spout (12a) into one attachment. Also, the mouthpiece (9
The positional relationship between a) and the spout (12a) is as follows:
) is placed on the front edge of the mouthpiece (9a) (Figures 3 and 4), and the entire periphery of the mouthpiece (9a) is surrounded by a spout (12g) (Figures 5 and 4). Several aspects are possible, such as the one shown in Figure 6). Furthermore, it is also conceivable that the air outlet (12a) K is provided with an air outlet (14) to increase the blow-up effect (see Figs. 7 and 8).

The present invention is constructed as described above.

After turning on the switch (4) with the handle +31 IC installed and starting the motor [61″4r: Let the spout (12a) lie on the floor.

Then, the dust on the floor is sucked in with air from the suction port (9m), passes through the suction hose (9), enters the dust collection bag (71), and the air that collects the dust with the collection jiffl + 71 passes through the impeller + 51 to the casing. You will be guided to the rear of (1).

In conventional practice, the air is discharged to the outside from an exhaust hole provided at the rear of the casing (1), but in the machine of the present invention, there is an air return passage (lO) inside the casing (1). Because of this, the air returns through the passage (10), passes through the return hose (12), and is ejected onto the floor from the ejection port (12a) facing the periphery of the suction port (9a) at the tip. Then, the dust on the floor is locally blown up by the jet K, and the next instant, it is sucked together with air from the suction port (9a). This operation is then repeated continuously to improve the cleaning effect.

In addition, in an embodiment in which a pressure reducing adjustment valve (13) is provided at the rear of the casing (11), the air flow that returns can be changed arbitrarily, so that the air flow from the tip outlet (12a) can be adjusted depending on the conditions of the floor, dust, etc. More effective dust collection can be achieved by adjusting the pressure.

As described above, the present invention uses a combination of the blowing action and suction action of air jets to prevent flies from persistently adhering to floors, carpets, etc., whereas the conventional machine uses only a suction method. It can easily suck up dust, and it can also effectively remove dust that has accumulated in the corners of a room or near walls.

Furthermore, since the air jet that causes the blow-up action uses the so-called exhaust gas as is, the power consumption is the same as that of conventional machines, making it economical.

From the above explanation, it will be easily understood that the present invention achieves the intended purpose. Further, the above explanation 811 and the drawings illustrate some preferred embodiments of the present invention, and it goes without saying that many design changes can be made without changing the gist of the present invention.
