Description

Vacuum cleaner {ELECTRIC CLEANER}

The present invention relates to a vacuum cleaner, and more particularly, to a vacuum cleaner having a basket for attaching a paper pack inside a dust collecting chamber of a cleaner body.

Background Art Conventionally, various vacuum cleaners in which paper packs are provided inside a dust collecting chamber have been proposed.

In particular, in recent years, a vacuum cleaner having a basket for attaching a paper pack is adopted in the dust collecting chamber so that the paper pack can be easily detached from the dust collecting chamber.

The conventionally used basket has a box shape so that dust can be collected inside the basket even when no paper pack is mounted, and a packing of a rubber product for preventing dust leakage is installed on the outer circumference of the upper edge of the basket.

Moreover, a large opening is formed in the side wall and bottom of a basket, and the filter etc. are attached.

In the vacuum cleaner provided with such a basket, when disposing of the paper pack after cleaning, the basket is removed from the dust collecting chamber, the clamp for fixing the paper pack is removed from the dust box, and the basket is turned upside down.

In addition, even when the carton is not used, the basket is taken out of the dust collecting chamber when the dust is discarded.

However, in the conventional vacuum cleaner, when the basket is installed in the dust collecting chamber, the flat outer circumferential surface of the packing at the top edge of the basket needs to be closely adhered to the inner wall of the dust collecting chamber of the cleaner body. It was difficult to set the basket with one touch because the basket was roughly held in hand and inserted into the dust chamber by pushing the basket downward to a predetermined position.

If there is no basket at a predetermined position (particularly, the position in the width direction of the cleaner body in the width direction), the hose is not inserted or the leak occurs first because the center of the hose insertion hole of the cleaner body and the suction port of the basket are displaced. there is a problem.

In addition, even when the basket is taken out, there is a problem that the packing of the basket is in close contact with the vacuum cleaner body, so that it is not easy to separate it with one touch.

The present invention has been made to solve such a problem, and an object of the present invention is to provide an electric vacuum cleaner that can easily and reliably install and remove a basket.

The vacuum cleaner shown in FIGS. 1 and 7 to 8 has an electric blower 2 and a dust collecting chamber 3 inside the cleaner main body 1, and a paper pack 4 inside the dust collecting chamber 3 (FIG. The basket 5 for attaching 7) is detachably installed.

In the upper part of the vacuum cleaner main body 1, the cover 6 for opening and closing the dust collecting chamber 3 is provided.

Moreover, the wheel 7 is provided in the lower part of the cleaner main body 1 so that the cleaner main body 1 may be rolled and moved on the floor surface.

Moreover, the suction inlet 1a is open in the front surface of the cleaner main body 1, and a hose etc. (not shown) are connected to this suction inlet 1a.

Moreover, the exhaust port 3b which communicates with the said electric blower 2 is formed in the inner wall surface (rear wall) 3a of the rear side of the dust collecting chamber 3.

As shown in Figs. 2 to 6, the basket 5 has a substantially box shape in which the upper part and the rear part are opened, and the rear opening is the take-out opening 9.

A mouth wall (rear wall) 8 is formed at the edge of the lower opening of the outlet 9.

The basket 5 is made of synthetic resin or the like.

In addition, the basket 5 has a handle 16 for pulling out and transporting the basket 5, a clamp 17 for fixing the carton 4, and the cleaner body 1 and the carton 4. The circular packing 14 for maintaining the sealing property of the basket 5 is provided.

As shown in FIG. 2 and FIG. 6, when the carton 4 is set in the basket 5, the fixing plate 10 fixed to the carton 4 may be sandwiched between the groove 15 and the clamp 17. .

On the contrary, when the paper pack 4 is taken out and discarded, only the clamp 17 is rotated upward.

The basket 5 of this embodiment presupposes using and installs the carton 4, and removes the packing 42 (refer FIG. 11) provided in the upper edge of the conventional basket 41, and also the cleaner main body A space | interval 24 (refer FIG. 8) is formed between 1 and the side wall 11 of the basket 5. As shown in FIG.

In addition, when the basket 5 is released from a certain position (height), the basket 5 slides in a predetermined position inside the dust collecting chamber 3 of the cleaner body, and the width of the cleaner body 1 is increased. The left and right positioning mechanisms 41 for positioning the basket in the right and left directions, and the front and rear and top and bottom positioning mechanisms 31 and 32, which will be described later, are provided.

By adopting such a structure, the basket 5 can be easily and securely installed at a predetermined position without being completely pushed into the dust collecting chamber 3 of the cleaner body 1, and the handle (when pulling out) 16) can be easily pulled up.

First, the left and right positioning mechanism 41 will be described.

9-13, the left-right positioning mechanism 41 extends downward from the handle 16 provided in the upper part of the front wall 12 of the basket 5, and front surface 3c of the dust collecting chamber 3 is shown. A pair of ribs 42a and 42b abutting on the left and right ends of the ribs 34 of () and the front surface of the dust collecting chamber 3 along the width direction of the cleaner body 1 to guide the basket 5. It consists of ribs 34 extending upward from the top edge of the wall 3c.

With this configuration, when the basket 5 is inserted into the dust collecting chamber 3, the pair of ribs 42a and 42b on the basket 5 side have left and right ends of the ribs 34 on the cleaner body 1 side. By pinching, the left and right positioning of the basket 5 can be performed.

Further, the left and right positioning mechanisms 41 may be a combination of a pair of ribs 42a and 42b and ribs 34 extending in the main body width direction as in the present embodiment, or a combination of convex portions and holes. do.

Here, as a comparative example, when the right and left positioning of the basket 5 is considered to be performed on the side wall 11 of the basket 5, there is a problem that the side wall 11 of the basket 5 is bent and the positioning is difficult.

On the other hand, as in the present embodiment, since the handle 16 itself exhibits the reinforcing effect of the basket 5, it is difficult to deform, so that positioning is made in the vicinity of the handle forming portion and near the suction port 1a. Since the error is small, the basket 5 can be positioned reliably, and the suction port 1a of the cleaner main body 1 and the connection port 13 of the basket 5 can be reliably matched.

Moreover, in this embodiment, since the taper parts 43a and 43b which become narrow on both ends of the rib 34 on the dust-collecting chamber 3 side toward the upper end are provided, the basket 5 is attached. In this case, the pair of ribs 42a and 42b on the handle 16 side are guided against the tapered portions 43a and 43b, so that the basket 5 can be easily mounted.

In addition, although not shown, if the taper part which becomes small in thickness as it goes to the lower end is formed in the mutually opposing surface of the pair of ribs 42a and 42b by the said handle 16 side, Since both edges of the 34 are guided abut, the basket 5 can be easily attached as described above.

The tapered portions 43a and 43b at both ends of the rib 34 and the tapered portions (not shown) of the pair of ribs 42a and 42b may be formed on either rib or are formed on both ribs. You may also do it.

Moreover, in this embodiment, as shown to FIGS. 10-13, the taper part (a illustration of taper part 43a) 43b (or pair of rib 42a, 42b) of the both ends of the said rib 34 is shown. When the basket 5 is mounted by guiding), a final left and right positioning mechanism 44 for final left and right positioning is also provided.

The final left and right positioning mechanism 44 is orthogonal to the pair of ribs 45a and 45b extending along the main body width direction at the bottom of the handle 16 on the basket 5 side. It consists of a pair of ribs 46a and 46b extending upward from the upper edge of the front wall 3c of the dust collecting chamber 3 along the front-back direction of the cleaner body 1.

As shown in FIG. 13, in the lower part of the handle 16 of the basket 5, a pair of ribs 45a and 45b are formed integrally with each of the pair of ribs 42a and 42b, which will be described later. It constitutes 33.

By the final left and right positioning mechanism 44, when the basket 5 is inserted to the inside of the dust collecting chamber 3, positioning of the basket 5 in the left and right direction together with the left and right positioning mechanism 41 is performed. This can be done more reliably.

Hereinafter, the front and rear, up and down positioning mechanisms 31 and 32 will be described in detail.

As shown in FIG. 9, the 1st front and rear, top and bottom positioning mechanism 31 is a rib 33 extended downward from the handle 16 provided in the upper part of the front wall 12 of the said basket 5, and a basket. (5) is composed of ribs 34 extending upward from the upper edge of the front wall 3c of the dust collecting chamber 3.

Here, the rib 34 is a common component to the first front and rear positioning mechanism 31 and the left and right positioning mechanism 41.

On the other hand, the second front, rear, top and bottom positioning mechanism 32 is upward from the recessed portion 35 formed outside the bottom wall 25 of the basket 5 and the bottom face 37 of the dust collecting chamber 3. The rib 36 is extended.

By this structure, first, the front, back, up and down positioning mechanism 31 performs positioning of the basket 5 and the vacuum cleaner main body 1 in the front and rear and up and down directions.

The ribs 33 on the basket 5 side sandwich the ribs 34 on the front wall 3c of the dust collecting chamber 3, so that the basket 5 is driven by the electric blower 2 when the electric blower 2 is in operation. Pulling to the (2) side is prevented.

The first front, rear, top and bottom positioning mechanisms 31 may be a combination of the ribs 33 and the ribs 34 as in the present embodiment, or may be a combination of the convex portions and the holes.

Positioning in the front-rear direction is made by the ribs 36 of the bottom surface 37 of the dust collecting chamber 3 by the second front, rear, top and bottom positioning mechanisms 32 as well as the first front, top, bottom positioning mechanisms 31. By sandwiching the recess 35 outside the bottom wall 25 of the basket 5, positioning of the basket 5 and the cleaning main body 1 in the front and rear and up and down directions is performed.

In addition, it is possible to prevent the basket 5 from being pulled toward the electric blower 2 during the operation of the electric blower 2 as described above by the second before and after positioning mechanism 32.

Moreover, as shown in FIG. 9, in order to guide the back side of the basket 5, the guide part protruding to the curved surface part 39 of the back of the basket 5, and the back wall 3a of the dust collecting chamber 3, Since the guide mechanism 38 which consists of ribs 40 is provided, the said basket 5 can be prevented from inclining when the basket 5 is injected into the dust collecting chamber 3.

Moreover, in this embodiment, as shown in FIG. 6, the connection port 13 connected to the suction port 1a of the said vacuum cleaner main body 1 is formed in the front wall 12 of the basket 5, The said connection port The packing 14 is provided in the circumferential edge of 13.

The packing 14 shown in FIG. 3 and FIG. 6 has a circular annular ring portion 14a having a semi-circular cross section in contact with the fixed plate 10, and a circular shape fitted to the inner circumferential surface of the connection port 13 into which the hose is inserted. A semicircular cross section contacting the annular fitting portion 14b, the valve portion 14c for freely opening and closing the connection port 13 and the inner surface of the front wall 3c of the dust collecting chamber 3 The circular ring-shaped ring portion 14d is formed.

By contacting the fixing plate 10 without any gap between the ring portions 14a, the gap between the front wall 12 and the fixing plate 10 is hermetically sealed.

At the same time, the gap between the inner wall of the dust collecting chamber 3 and the front wall 12 is hermetically sealed by the ring 14d contacting the inner wall of the dust collecting chamber 3 without any gap.

3 and 6, since the basket 5 is provided with ribs 5a for supporting the semicircular maximum outer peripheral portion 14e of the ring portion 14d of the packing 14, the ring portion 14d is provided. ) Can be prevented from tipping or jamming.

Moreover, in this embodiment, the handle 16 and the said clamp 17 are provided in the front wall 12 of the basket 5.

Specifically, an arcuate handle 16 is fixed to the front wall 12 of the basket 5 by a protrusion 18 (see FIG. 3) protruding downward from both ends of the handle 16. have.

Inside the space surrounded by the handle 16, the clamp 17 is freely swinged by a pair of shafts 19 (see Fig. 3) protruding from both sides.

As shown in FIG. 6, the clamp 17 is always applied with a force in the direction in which the fixing plate 10 is fitted by the spring 20.

In the case where the paper pack 4 is discarded by such a structure, it is performed as follows.

First, with the cartons 4 installed in the basket 5, the basket 5 is pulled out from the cleaner body 1 by holding the handle 16, and the handle 16 is held by the hand on the front wall 12 side. Rotate the clamp (17) upwards to remove it.

In this embodiment, since the rear surface of the box-shaped basket 5 is used as the outlet 9, and the handle 16 is provided in the front end of the basket 5, when the handle 16 is caught, the basket 5 is carried out. The back of the goes down.

As a result, the paper pack 4 can be easily discarded by natural fall.

Therefore, it is possible to easily dispose of the cartons 4 without holding the handle 16 by hand and reverse the basket 5.

In addition, the clamp 17 can be operated by one hand holding the handle 16, which is convenient.

On the other hand, in the case of replacing the carton 4, the carton 4 is attached to the basket 5 outside the cleaner body 1, and then the handle 16 is held by the handle 5 to hold the basket 5 in the cleaner body 1. It can be easily attached to.

Furthermore, in the past, when the basket with a filter is used without a carton, the suction performance has been reduced by clogging of the filter by dust or the like. However, in the present embodiment, as shown in Figs. 2 and 4 in order to prevent a decrease in the suction performance. Assuming that the carton pack 4 is used, at least one opening 22 for ventilation is formed in at least the side wall 11 of the basket 5.

Moreover, as shown in FIG. 8, the some clearance gap 24 is formed between the basket 5 and the inner side wall 23 in the dust collection chamber 3 of the vacuum cleaner main body 1. As shown in FIG.

Therefore, the opening 22 of the side wall 11 of the basket 5 communicates with the electric blower 2 via the gap 24 and the exhaust port 3b.

This configuration ensures a flow path of air to the opening 22, so that it can be sucked evenly inside the carton 4, and dust can be collected not only on the back side but also on the side of the carton 4, thereby preventing deterioration of suction performance. There is a number.

The opening 22 can also be formed in the bottom wall 25 of the basket 5 shown in Figs. 2 and 7 to 8, and in that case as well, it is possible to prevent the deterioration of suction performance. Instead of forming the opening 22 in the bottom wall 25, as shown in Figs. 2 and 7 to 8, in order to prevent the paper pack 4 and the bottom wall 25 from coming into close contact with each other, the planar protrusions ( By protruding 26), it is possible to prevent deterioration of suction performance without dust, dust, or the like coming out of the basket 5 to the dust collecting chamber 3.

According to the present invention, since the right and left positioning mechanisms for the baskets are provided, the baskets can be attached and detached easily and reliably.

In addition, by providing the front and rear and top and bottom positioning mechanisms for the basket, the basket can be attached and detached easily and reliably.
