Description

Electric vacuum cleaner {A VACUUM CLEANER}

The present invention relates to a vacuum cleaner. More particularly, it relates to a canister type vacuum cleaner having a cyclone dust box.

Conventional vacuum cleaners, especially upright type (vertical) vacuum cleaners, do not use disposable dust collecting paper packs, and are freely attached to the suction path of the vacuum cleaner body, and generate a vortex-like air flow (so-called cyclone) inside. It is known to use a cyclone dust collector provided with a cylindrical filter in the dust collecting case and allowing the dust filtered by the filter to be accumulated in the dust collecting case. This dust collector is economical since it can be used semi-permanently by the maintenance of a filter compared with a disposable carton.

MEANS TO SOLVE THE PROBLEM The present inventors earnestly examined about using such an economical dust collection efficiency cyclone type dust collector for a canister type (horizontal type) vacuum cleaner, and the canister type which installed the cyclone type dust box in the cleaner main body. Has developed a vacuum cleaner.

Conventionally, in the upright type | mold cyclone type vacuum cleaner, a dust box is detachably attached to a vacuum cleaner main body. For example, when a dust box having an inlet and an exhaust port is formed on one side, the dust box first aligns the portion to be a point, and then rotates the dust box to position the inlet and exhaust ports, respectively.

However, in such a configuration, the dust box alignment is cumbersome and not easy to use. In addition, when a cyclone type dust box is conventionally used in a canister type vacuum cleaner, since an air inlet and an exhaust port need to be located on one side side, a blower path connected to either of the inlet port or the exhaust port is provided. It is necessary to install up to the position opposite to the connector or the electric blower to which the suction hose is connected so as to turn around, and the blower becomes complicated, and the suction efficiency is deteriorated.

On the other hand, in order to solve the problem of the alignment of the dust box, in the canister type vacuum cleaner, it was devised to let the dust box in and out.

However, in such a configuration, in order to see and know the amount of dust accumulated in the dust box, it is necessary to make the dust box visible from the side of the cleaner body. Therefore, since the rear part of the cleaner body and the front wall of the suction hose are separated, the strength of the cleaner body is weak.

The present invention has been made to solve such a problem, and an object of the present invention is to provide a cyclone-type canister type vacuum cleaner which can see and know the situation inside the dust box and can suppress the deterioration of the strength of the entire vacuum cleaner. do.

In the vacuum cleaner of the present invention, a cyclone-type dust box is provided at the front of the canister type vacuum cleaner main body, and an electric blower storage chamber is formed at the rear of the vacuum cleaner main body. For example, a front wall having a connector is provided to connect the suction hose, and the rear upper portion of the cleaner body and the front wall are connected by a connecting portion extending around the side of the dust box. At least one opening is formed between the connecting portion and the bottom of the cleaner body to expose the side surface of the dust box.

It is preferable that the rear portion and the connecting portion of the cleaner body are integrally formed.

Similarly, the inner filter part 7 consists of the inner normal member 11 and the inner filter 12 which covers the circumference | surroundings of the some slit 11a formed along the longitudinal direction in the inner side normal member 11 side.

Moreover, on the outer peripheral side surface of the inner side normal member 11, the shading part 13 extended toward the inner wall of the outer side normal member 8 protrudes. A gap 35 is formed between the inner wall of the outer normal member 8 and the shade portion 13. Accordingly, the second cyclone space 27 surrounded by the inner wall of the outer normal member 8, the inner filter 12, and the shade 13 between the inner wall of the outer normal member 8 and the inner filter part 7. And a space portion 28 for collecting dust communicating with the second cyclone space 27 through the gap 35.

Like the shade portion 10, the tip portion 13a of the shade portion 13 is also bent downward so that when dust moves from the second cyclone space 27 to the space portion 28 through the gap 35, This is preferable because less dust is caught on the tip portion 13a.

As shown in FIG. 6, the outer filter part 6 and the inner filter part 7 are stuck in the state which dripped down the upper lid part 14 which closes the upper opening of the dust box main body 5. As shown in FIG.

Specifically, the intermediate lid portion 8b, which is extended on the upper portion of the outer normal member 8, is fitted to the inner wall of the upper lid portion 14 in a state where the sealing 8c is fitted. Between the middle lid part 8b and the dust box main body 5 is hermetically sealed by the seal ring 8d provided in the edge part of the intermediate lid part 8b. On the other hand, the cylindrical holder 11b which has several slits extended on the upper part of the inner side normal member 11 is inside the upper lid part 14 in the state which hold | maintained the cylindrical filter 29. Housed in Between the cylindrical holder 11b and the inner lid part 8b is hermetically sealed by the sealing 11c provided in the lower end of the outer peripheral surface of the cylindrical holder 11b.

An intake pipe 15 protrudes from the side of the dust box 2, and the front end side opening 16 of the intake pipe 15 is formed at the center of the width direction of the vacuum cleaner main body 4 (FIG. 1 and FIG. 1). It is formed in the approximate center part of the width direction of the dust box 2 so that it may be connected directly with FIG.

In addition, in the vicinity of the inferior opening 17 of the intake pipe 15 on the inner surface of the dust box 2, the guide rib 18 is extended in the direction along the inner surface of the dust box 2, so that such a guide is provided. The flow direction of the cyclone generated inside the dust box 2 through the intake pipe 15 to the inside of the dust box 2 by the ribs 18 (for example, in the clockwise direction in FIG. 8). ). For this reason, the air containing the dust sucked in the intake pipe 15 shown in FIG. 8 turns in the dust box 2, and can bring high dust collection efficiency.

In addition, as shown in FIG. 6, the bottom cover 21 is attached to the bottom of the dust box main body 5 freely opened and closed by a hinge 20 provided below the handle 19. This bottom cover 21 presses the upper part of the lever 22 provided below the intake pipe 15, so that the clamp 23 formed in the lower end of the lever 22 has the hook ring 24 on the bottom cover 21 side. ), The lower end opening of the dust box main body 5 is opened.

The type and material of the outer filter 9 and the inner filter 12 are not particularly limited in the present invention. For example, a mesh filter may be provided on the outer circumference of a normal body which is a passage of filtered air. A filter or the like arranged in a tubular shape is employed. Moreover, other filters, such as the filter which provided the filter paper filter fold | folded in the shape of a pleat, can be employ | adopted.

Next, each flow of dust and air in the vacuum cleaner of the present embodiment will be described.

Turn along the inner wall of the house. Specifically, in the first cyclone space 25 surrounded by the inner wall of the dust box main body 5, the outer filter 9, and the shade 10, the air is turned into the outer filter 9 while turning. The large dust (rough dust) is accumulated in the space portion 26 of the bottom of the dust box main body 5 through the gap 34 between the inner wall of the dust box main body 5 and the shade 10.

Similarly, the air which flowed inside the outer filter 9 also turns. Specifically, in the second cyclone space 27 surrounded by the outer normal member 8, the inner filter 12, and the shade 13, air flows inside the inner filter 12 while turning, The dust is deposited in the space portion 28 of the bottom of the dust box body 5 through the gap 35 between the outer normal member 8 and the shade portion 13.

Moreover, since the packing 36 is provided in the bottom cover 21 in order to close the clearance gap between the bottom edge of the outer side normal member 8, and the bottom cover 21, the space part along the bottom cover 21 is provided. No air leaks from the space 26 to the space 28.

The dust filtered by the dust box body 5 is filtered again by the cylindrical filter 29 inside the upper lid 14, and then dust box than the exhaust port 30 behind the upper lid 14. (2) After going out, it is put into the electric blower 3 through the connecting passage 31 shown in FIG. 7 and filtered through the exhaust filter 32 in the electric blower 3, It is discharged to the outside through the mesh of the mesh-shaped exhaust port 24 and the rear wheel 1b or 1c which were formed.

11 and 14, since the lower side of the bag-shaped case cover 44 is closed by the case cover lower 47, even if the case cover 44 is viewed from below through the opening 39, the case The reinforcement ribs etc. inside the cover 44 are not seen, and the appearance improves. In addition, since the case cover 44 is reinforced by the case cover row 47, the strength is greatly improved.

The vacuum cleaner of the present invention can be seen by seeing the dust inside the dust box 2 from the outside if at least the dust box body 5 (see FIG. 5) of the dust box 2 is transparent or translucent. In addition, in consideration of the design of the entire vacuum cleaner, when the entire dust box 2, the case upper 43 and the handle 52 (see FIG. 13) of the vacuum cleaner body 1 are made transparent or translucent, the appearance becomes more beautiful. It is desirable because it gives a light and light impression.

However, when the transparent handle 52 is attached as shown in Fig. 13, the screw boss 43a on the case upper 43 side, and the reinforcing ribs (not shown) of the screw boss are visible from the outside, which is poor in appearance. not. Thus, by wrapping the outer circumference of the screw boss 43a with a smoother ordinary rib 53, the strength and appearance of the attachment portion of the handle 52 can be improved. Normally, the rib 53 is fitted into a groove portion (not shown) formed in the handle 52 cross section.
