TECHNICAL FIELD OF THE INVENTION
The present invention relates to a vacuum cleaner. More particularly, the present invention relates to a vacuum cleaner having a basket for mounting a paper pack inside a dust collection chamber of a vacuum cleaner body.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, various vacuum cleaners in which a paper pack is mounted inside a dust collection chamber have been proposed. In particular, in recent years, a vacuum cleaner having a basket for mounting a paper pack is provided inside the dust collection chamber so that the paper pack can be easily attached to and detached from the dust collection chamber.
[0003]
Conventionally used baskets have a box shape 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 the bottom surface of the basket. Has a filter attached.

FIG. 1 is an explanatory perspective view of a vacuum cleaner main body according to an embodiment of the present invention in a state where a lid of the vacuum cleaner body is opened, FIG. 2 is an enlarged perspective view of the basket of FIG. 1, and FIG. 3 is a basket of FIG. 4, FIG. 4 is a side view of the basket of FIG. 1, FIG. 5 is a plan view of the basket of FIG. 1, FIG. 6 is a sectional explanatory view showing a state where a paper pack is mounted on the basket of FIG. 1, and FIG. FIG. 8 is a partially cutaway side view in a state where a basket and a paper pack are mounted on the cleaner body of FIG. 1 and FIG. 8 is a partially cutaway plan view in a state where a basket is mounted on the cleaner body of FIG.
[0014]
The vacuum cleaner shown in FIG. 1 and FIGS. 7 and 8 has an electric blower 2 and a dust collection chamber 3 inside a cleaner main body 1, and a paper pack 4 (see FIG. 7) inside the dust collection chamber 3. ) Is detachably provided.
[0015]
A lid 6 for opening and closing the dust collection chamber 3 is provided at an upper portion of the cleaner body 1. Wheels 7 are provided below the cleaner body 1 so that the cleaner body 1 can be moved by rolling on the floor. Further, a suction port 1a is opened on the front surface of the cleaner body 1, and a hose or the like (not shown) is connected to the suction port 1a. 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.
[0016]
As shown in FIGS. 2 to 6, the basket 5 has a substantially box shape with an upper portion and a rear portion opened, and has a rear opening as an outlet 9. An upright wall (rear wall) 8 is formed at the lower opening edge of the outlet 9. The basket 5 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, a clamp 17 for fixing the paper pack 4, and a seal for the basket 5 with respect to the cleaner body 1 and the paper pack 4. Is provided.
[0017]
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 taking out and discarding the paper pack 4, it is only necessary to rotate the clamp 17 upward.
[0018]
In the present embodiment, since the outlet 9 is formed on the rear surface of the basket 5, the paper pack 4 mounted inside the basket 5 can be easily discarded by natural fall through the outlet 9, As a result, convenience is improved. In addition, even if the paper pack 4 is swollen by dust or the like and becomes almost full, the paper pack 4 is stuck on the four side walls (the rear wall 8, the side wall 11 and the front wall 12 in the case of the basket 5 in FIG. 2) and cannot be removed. No defects.
[0019]
In the present embodiment, an example in which the outlet 9 is formed on the rear surface is described. However, the present invention is not limited to this. Similarly, the paper pack 4 can be easily taken out of the basket 5 through the outlet 9 and discarded.
[0020]
A connection port 13 communicating with the suction port 1a of the cleaner body 1 is formed on the front wall 12 of the basket 5, and a packing 14 is provided on the periphery of the connection port 13.
[0021]
The packing 14 shown in FIGS. 3 and 6 has an annular ring portion 14 a having a semicircular cross section that comes into contact with the fixing plate 10, and an annular ring portion fitted on the inner peripheral surface of the connection port 13 into which the hose is inserted. It is composed of a fitting portion 14b, a valve portion 14c for opening and closing the connection port 13, and an annular ring portion 14d having a semi-circular cross-section to contact the inner surface of the front wall 3c of the dust collecting chamber 3. .
[0022]
Since 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.
[0023]
Further, as shown in FIGS. 3 and 6, the basket 5 is provided with the rib 5a for receiving the semicircular maximum outer peripheral portion 14e of the ring portion 14d of the packing 14, so that the ring portion 14d is turned upside down. It can prevent catching.
[0024]
In the present embodiment, a standing wall (rear wall 8) is formed at the lower opening edge of the outlet 9 of the basket 5, so that fine dust or the like is collected in the basket 5 without being collected by the paper pack 4. However, since the dust is guarded by the rear wall 8, fine dust does not spill when the paper pack 4 is discarded (the basket 5 is tilted).
[0025]
The height of the rear wall 8 (in other words, the size of the outlet 9) is not particularly limited in the present invention. It may be left so that it is not high enough.
[0026]
When the outlet 9 is formed in the side wall 11, dust and the like do not spill into the dust collecting chamber 3 as described above, except for the vicinity of the lower end of the side wall 11.
[0027]
Further, in the present embodiment, since the outlet 9 is formed on the rear surface portion (that is, the side close to the electric blower 2), the outlet 9 communicates between the electric blower 2 and the paper pack 4. Thereby, the suction performance can be improved.
[0028]
Further, in the present embodiment, a handle 16 and the clamp 17 are provided on the front wall 12 of the basket 5. 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, a clamp 17 is swingably mounted by a pair of shafts 19 (see FIG. 3) projecting from both sides. As shown in FIG. 6, the clamp 17 is constantly urged by a spring 20 in a direction to clamp the fixed plate 10.
[0029]
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 the clamp 17 on the front wall 12 is rotated upward while holding the handle 16 with the hand. Remove it. In this embodiment, the rear surface of the basket 5 is lowered when the handle 16 is held because the rear surface of the basket 5 is the outlet 9 and the handle 16 is attached to the front end of the basket 5. As a result, the 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. In addition, the clamp 17 can be operated with one hand with the hand holding the handle 16, which is convenient.
[0030]
On the other hand, when replacing the paper pack 4, the paper pack 4 can be 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. it can.
[0031]
As shown in FIG. 6, the position of the handle 16 is located on the foremost side (the front wall 12 side) of the basket 5. Therefore, when the basket 5 attached to the cleaner body 1 is pulled up, Due to the center of gravity of the basket 5, the rear side of the basket 5 (the rear wall 8 side) is inclined downward. As a result, the suction opening 21 of the paper pack 4 is directed upward, so that dust and dust are less likely to leak when the basket 5 is transported.
[0032]
In addition, since the clamp 17 is rotated while the rear side of the basket 5 is tilted as described above, the paper pack 4 can be easily dropped through the outlet 9 on the rear side of the basket 5. Can be.
[0033]
By arranging the handle 16 and the clamp 17 of the basket 5 as described above, it is possible to improve the convenience of taking out, attaching, and transporting the basket 5, and attaching and discarding the paper pack 4. Moreover, in the conventional basket, a rubber packing for preventing dust from leaking is provided on a peripheral edge of an upper end of the basket so that dust can be collected without a paper pack. Since it is intended to be used with no packing, there is no packing, and mounting and dismounting become easier.
[0034]
Further, in the related art, when a basket with a filter is used without a paper pack, suction performance has been reduced due to clogging of the filter due to dust or the like.In the present embodiment, however, in order to prevent a reduction in suction performance, 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.
[0035]
The present invention does not particularly limit the shape, the number, and the arrangement of the ventilation openings 22. Therefore, the shape of the opening 22 may be a round hole as shown in FIG. 4 or a square hole. As shown in FIG. 4, the number of the openings 22 may be such that about 16 small-diameter holes are formed in each side wall, or one large-diameter hole is formed in each side wall 11 to form the periphery of the hole. A reinforcing rib may be formed on the base. Further, the arrangement of the openings 22 may be such that a plurality of openings 22 are regularly arranged vertically and horizontally, as shown in FIG. 4, or may be dispersedly arranged.
[0036]
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 such a 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 accumulated not only on the rear surface but also on the side surface of the paper pack 4, thereby reducing the suction performance. Can be prevented.
[0037]
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 a decrease in suction performance as described above. Instead of forming the opening 22, as shown in FIGS. 2 and 7 to 8, if a sheet-like projection 26 for preventing the close contact between the paper pack 4 and the bottom wall 25 is protruded, the collection from the basket 5 is performed. It is possible to prevent the suction performance from lowering without spilling dust or dirt into the dust chamber 3.
[0038]
As described above, the use of the paper pack 4 and the provision of the ventilation openings 22 and the planar protrusions 26 make it possible to compare with a conventional vacuum cleaner in which a filter is attached to a basket without using a paper pack. As a result, the filter is not clogged, the suction performance can be prevented from lowering, and the number of parts can be reduced to reduce costs.
[0039]
【The invention's effect】
According to the present invention, by forming an outlet for a paper pack on the side portion or the rear surface portion of the basket, it is easy to remove the paper pack even when it is full, and it is opened when the paper pack is discarded. It becomes possible to drop naturally from the part where it fell, and convenience is improved.
