[0001] The present invention relates to a vacuum cleaner. More specifically, the present invention relates to an electric vacuum cleaner having a basket inside a dust collecting chamber of a main body of the vacuum cleaner.

[0002]

2. Description of the Related Art Conventionally, various vacuum cleaners having a basket inside a dust collection chamber have been proposed. In particular, in recent years, a vacuum cleaner having a paper pack mounting basket provided inside the dust collection chamber has been adopted so that the paper pack can be easily attached to and detached from the dust collection chamber.

[0003] Conventionally used baskets are box-shaped so that dust can be collected inside the basket even when a paper pack is not mounted, and openings for ventilation are formed in the side walls and bottom surface of the basket. A filter or the like is attached to this opening.

In a vacuum cleaner having such a basket, when replacing the paper pack after cleaning, first, open the lid at the top of the cleaner body, take out the basket from the dust collection chamber, and remove the paper pack from the basket. Was replaced with a new one, and the basket was placed in the dust collection chamber again, and finally the lid was closed. Alternatively, when using without a paper pack, the garbage collected directly in the basket is discarded instead of the above-described exchange of the paper pack, and other operations are the same as those with the paper pack.

[0005]

However, in the case of a conventional vacuum cleaner equipped with a basket, for example, when replacing a paper pack, after removing the basket from the dust collection chamber, the lid is inadvertently left unattached while the basket is not mounted. May be closed and cleaned. In this case, there is a problem that dust and the like are directly filled in the dust collection chamber.

Further, when the lid is closed in a state where the basket is not correctly mounted at a predetermined position even when the basket is mounted in the dust collecting chamber,
The suction port (hose connection port) on the main body side of the vacuum cleaner and the connection port (hose connection port) on the basket side do not match, so that there is a disadvantage that the hose cannot be inserted.

The present invention has been made in order to solve such a problem, and it is possible to easily and reliably confirm whether or not a basket is not mounted or is not correctly mounted at a predetermined position. An object is to provide a vacuum cleaner.

Another object of the present invention is to provide a vacuum cleaner capable of accurately mounting a basket at a predetermined position when a lid is closed.

FIG. 15 is a partial plan view showing a state where the basket of the cleaner main body of FIG. 1 is mounted, and FIG. 16 shows a state where the basket of the cleaner main body of FIG. 1 is mounted. FIG. 17 is a cross-sectional explanatory view showing a state where the basket of the cleaner main body of FIG. 1 is being mounted.

The electric vacuum cleaner shown in FIG. 1 and FIGS. 7 and 8 has an electric blower 2 and a dust collecting chamber 3 inside a cleaner main body 1.
A basket 5 for mounting a paper pack 4 (see FIG. 7) is detachably provided inside the dust collection chamber 3. Further, the vacuum cleaner shown in FIG. 1 includes a mechanism 41 (hereinafter, referred to as a poker avoiding mechanism) for inhibiting the lid 6 from being fully closed when the basket 5 is not mounted at a predetermined position. . In addition, although the poker avoiding mechanism 41 is omitted in FIG. 8, it is shown in detail in FIG.

A lid 6 for opening and closing the dust collecting chamber 3 is provided at an upper portion of the cleaner body 1. In addition, the cleaner body 1
Wheels 7 are provided at a lower part of the cleaner so that the cleaner body 1 can be moved by rolling on the floor surface. Furthermore, the vacuum cleaner body 1
An opening 1a is opened at the front of the device, and a hose or the like (not shown) is connected to the opening 1a. Also,
An exhaust port 3b communicating with the electric blower 2 is formed on an inner wall surface 3a on the rear side of the dust collecting chamber 3.

As shown in FIGS. 2 to 6, the basket 5 has a substantially box shape with an upper portion and a rear portion opened.
The rear opening is an outlet 9. An upright wall (rear wall) 8 is formed at a lower opening edge of the outlet 9. Basket 5
It is made of a synthetic resin or the like. Further, the basket 5 has a handle 16 for pulling out and transporting the basket 5 and a clamp 1 for fixing the paper pack 4.
7, and a circular packing 1 for maintaining the sealing property of the basket 5 with respect to the cleaner body 1 and the paper pack 4.
4 (the details will be described later).

As shown in FIGS. 2 and 6, when the paper pack 4 is set in the basket 5, the fixing plate 10 fixed to the paper pack 4 may be fitted between the groove 15 and the clamp 17. Conversely, when the paper pack 4 is taken out and discarded, it is only necessary to rotate the clamp 17 upward.

The poker avoiding mechanism 41 is for confirming not only the presence or absence of the basket 5 but also whether or not the basket 5 is at a predetermined position. For example, as shown in FIG. 1 and FIGS. A holder 42 fixed to the front inner wall of the dust collecting chamber 3 of the cleaner main body 1, and the holder 42 swings in the front-rear direction of the cleaner main body 1, that is, a position interposed between the lid 6 and the cleaner main body 1. And a lever 43 provided to be able to swing between a position where the dust collection chamber 3 is closed by retreating to the inside of the dust collection chamber 3, and one end 43 a of the lever 43 is cleaned with the lid 6. And a spring 44 for urging the lever 43 in a direction to move the lever 43 to a position interposed between the main body 1 and the other end 43b of the lever 43. Of the end 43a into the dust collection chamber 3 And it is adapted to.

In the present embodiment, the lever 43 is connected to the dust collection chamber 3
Although the present invention is not limited to this configuration, the lever 43 may be configured to swing inward and outward of the dust collection chamber 3 if the lever 43 swings inward and outward. 43 may be provided on the side of the dust collection chamber 3.

Shafts 46 formed on both sides of the lever 43
Are rotatably supported by the holder 42. Spring 44
Is built in the holder 42 in a compressed state so as to urge the other end 43b of the lever 43 outward. The spring 44 only needs to apply a rotational urging force to the lever 43, and various springs such as a torsion coil spring may be employed.

When the basket 5 is not mounted in the dust collection chamber 3 by the poker avoiding mechanism 41, FIGS.
As shown in FIG. 14, one end 43a of the lever 43
Is urged by a spring 44, and pivots around a shaft 46, which is a fulcrum, to a position above the main body opening end 45. If the lid 6 is to be closed in this state, since the lever 43 is sandwiched between the lid 6 and the main body opening end 45, the lid 6 is not fully closed. Therefore, the user can easily and surely confirm that the basket 5 is not yet mounted in the dust collection chamber 3 because the lid 6 is not fully closed.

Moreover, even when the basket 5 is not correctly mounted at a predetermined position inside the dust collecting chamber 3, the lever 43 is sandwiched between the lid 6 and the main body opening end 45, so that the lid 6 is in the fully closed state. Does not. For example, when the basket 5 is mounted so as to be biased in the front-rear direction, the lever 43 rotates and is sandwiched between the lid 6 and the main body opening end 45.

Also, when the basket 5 is mounted eccentrically in the vertical direction, the lever 43 swings. Specifically, as shown in FIG. 16, the tapered portion 36 a of the projection 36 projecting from the bottom surface of the dust collection chamber 3 presses the concave portion 35 on the bottom surface of the basket 5 toward the suction port 1 a (front side). Therefore, the basket 5 is inserted straight down to the middle of the dust collecting chamber 3, but is pushed forward by the tapered portion 36a. Therefore, also when the basket 5 is mounted eccentrically in the vertical direction, the lever 43 reacts in the same manner as in the case of the front-rear direction.

Further, even when the basket 5 is mounted eccentrically in the left-right direction (the width direction of the main body), the basket 5 has tapered portions (for example, tapered portions at the lower ends on both sides of the basket 5 shown in FIG. 3). Therefore, the lever 43 swings.

On the other hand, when the basket 5 is correctly mounted on the dust collecting chamber 3 at a predetermined position, the other end 43
When b is pressed by the basket 5, the lever 43 rotates about the shaft 46, and one end 43a of the lever 43 is disengaged from the opening end 45 of the main body and retracts inside the dust collection chamber 3. Therefore, the lid 6 can be completely closed.

It is to be noted that the poker avoiding mechanism of the present invention is not limited to a basket for mounting a paper pack as in the present embodiment,
Needless to say, the attachment state can be checked even for a basket without a paper pack.

As shown in FIGS. 16 and 17, a pushing portion 47 for pushing the basket 5 into a predetermined position in the dust collecting chamber 3 is provided on the inner surface of the lid 6. Therefore, the basket 5 can be pushed into the interior of the dust collection chamber 3 simply by closing the lid 6, and can be easily and reliably set at a predetermined position.

In addition, at least a part of the inner wall of the dust collecting chamber 3 is formed as an inclined part which is inclined in a forward direction toward the bottom of the dust collecting chamber 3, for example, the tapered portion 36a and the dust collecting chamber 3 Is formed with a tapered portion 40a of the rib 40 on the rear side. Therefore, simply pushing the basket 5 into the interior of the dust collecting chamber 3 by the pushing portion 47 pushes the basket 5 toward the suction port 1a by the tapered portions 36a and 40a, so that the basket 5 can be accurately set at a predetermined position. The lever 43 is in the retracted position (body opening end 45).
(Position deviating from the position), and the lid 6 is closed.

On the front wall 12 of the basket 5, there is formed a connection port 13 communicating with the suction port 1a of the cleaner body 1, and a packing 14 is provided on the periphery of the connection port 13.

The packing 14 shown in FIGS. 3 and 6
A ring-shaped ring portion 14a having a semicircular cross-section that comes into contact with the fixing plate 10, an annular fitting portion 14b fitted on the circumferential surface of the connection port 13 into which the hose is inserted, and the connection port 13 And a ring portion 14d having a semicircular cross-section and in contact with the inner surface of the front wall 3c of the dust collecting chamber 3.

When the ring portion 14a contacts the fixed plate 10 without any gap, the space between the front wall 12 and the fixed plate 10 is hermetically sealed. At the same time, the ring portion 14d comes into contact with the inner wall of the dust collecting chamber 3 without any gap, thereby hermetically sealing the space between the inner wall of the dust collecting chamber 3 and the front wall 12.

Further, as shown in FIGS. 3 and 6, since the basket 5 is provided with a rib 5a for receiving the semicircular maximum outer peripheral portion 14e of the ring portion 14d of the packing 14, the ring portion 14d is provided. It can prevent turning over and catching.

Further, in the present embodiment, the basket 5
A handle 16 and the clamp 17 are provided on the front wall 12 of the vehicle. Specifically, a handle 16 having an arched shape is fixed to the front wall 12 of the basket 5 by claws 18 (see FIG. 3) projecting downward from both ends of the handle 16. Inside the space surrounded by the handle 16,
The clamp 17 has a pair of shafts 19 projecting from both sides.
(See FIG. 3).
As shown in FIG. 6, the clamp 17 is constantly urged by a spring 20 in a direction to clamp the fixed plate 10.

With such a structure, when the paper pack 4 is discarded, it is performed as follows. First, with the paper pack 4 attached to the basket 5, the basket 5 is pulled out from the cleaner body 1 with the handle 16, and while holding the handle 16 by hand, the clamp 17 on the front wall 12 is rotated upward. Remove it. In the present embodiment, since the rear surface of the box-shaped basket 5 is the outlet 9, and the handle 16 is attached to the front end of the basket 5, the back of the basket 5 is lowered when the handle 16 is held. As a result, paper pack 4
Can be easily disposed of by natural fall. Therefore, the paper pack 4 can be easily discarded without turning the basket 5 upside down while holding the handle 16 by hand. Further, the clamp 17 can be operated with one hand with the hand holding the handle 16, which is convenient.

On the other hand, when replacing the paper pack 4,
The paper pack 4 is mounted on the basket 5 outside the cleaner main body 1, and then the basket 5 can be easily mounted on the cleaner main body 1 by holding the handle 16.

The vacuum cleaner of the above-described embodiment is provided with a flicker avoiding mechanism 41 for confirming whether or not the basket 5 is at a predetermined position. It also has a function to confirm the presence or absence of a paper pack that does not close. For example, as shown in FIG. 7, a protrusion 17 a is provided to project upward from the clamp 17, and when the paper pack 4 is not mounted, the protrusion 17 a hits a rib 48 provided on the inner surface of the cover 6 to hold the cover 6. It does not have to close.

Further, conventionally, when a basket with a filter is used without a paper pack, the suction performance has been reduced due to clogging of the filter due to dust or the like. In the present embodiment, the suction performance is prevented from lowering. As shown in FIGS. 2 and 4, at least one ventilation opening 22 is formed in at least the side wall 11 of the basket 5 on the assumption that the paper pack 4 is used.

As shown in FIG. 8, a slight gap 24 is formed between the basket 5 and the inner side wall 23 of the dust collecting chamber 3 of the cleaner body 1. Therefore, the opening 22 of the side wall 11 of the basket 5 communicates with the electric blower 2 through the gap 24 and the exhaust port 3b. With this configuration, a flow path of air to the opening 22 is secured, so that the air can be uniformly sucked into the inside of the paper pack 4 and dust can be collected not only on the rear surface but also on the side surface of the paper pack 4, and the suction performance is reduced. Can be prevented.

The opening 22 can be formed in the bottom wall 25 of the basket 5 shown in FIG. 2 and FIGS. 7 and 8. In this case as well, it is possible to prevent the suction performance from being lowered as described above. Instead of forming the opening 22 in the wall 25, FIG.
And the paper pack 4 and the bottom wall 2 as shown in FIGS.
By protruding the planar protrusion 26 to prevent the close contact with 5,
Deterioration of suction performance can be prevented without dust or dust spilling from the basket 5 to the dust collection chamber 3.

[0040]

According to the first aspect of the present invention, by providing the mechanism for avoiding poker, it is possible to determine whether or not the basket is not mounted or is not correctly mounted at a predetermined position. , Can be easily and surely confirmed by whether or not the lid can be fully closed.

According to the third aspect of the present invention, since the pushing portion for pushing the basket into the interior of the dust collecting chamber is provided, the basket can be easily and reliably set at the predetermined position only by closing the lid. Can be.
