Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vacuum cleaner using a paper bag filter to collect dust, and particularly to the shape of the suction port of the paper bag filter.

Conventionally, the suction port of a paper bag filter is equipped with a separate rubber curtain to prevent the garbage inside the paper bag from flowing back when the paper bag is thrown away. Another method is to make the diameter smaller than the diameter of the main body connection part of the hose. In particular, what is closest to the present invention is to cut the suction port of the paper bag's mounting plate into 6 and 8 equal parts with radial perforations, and when setting the paper bag filter, cut the perforations with the current variable plate on the front lid. Tear it in place and use it to prevent backflow. However, the paper deforms and the backflow prevention effect is low. There is a decrease in performance due to the smaller air inlet.

The purpose of the present invention is to prevent the harmful effects of residue from the suction port on paper bags during the gluing process in the paper bag manufacturing process, to increase productivity, and to prevent the front cover from being removed when the front cover is opened when disposing of garbage. To provide a vacuum cleaner which houses a paper bag filter and eliminates dust that adheres to a current changing plate and is pulled out.

In the present invention, in order to achieve the above-mentioned purpose, instead of completely punching out the part of the paper bag at the suction opening of the paper bag, a part of the punching allowance is placed in the original place where the slag was punched out. In addition, by punching out a size that does not reduce the air intake area when attaching the front cover, it improves the productivity of paper bags and improves hygiene when disposing of garbage. done.

The interior is divided into a motor storage chamber 7, a cord winding device storage chamber 8, a collection/dust removal device storage chamber 9, a parts storage chamber 10, an exhaust chamber 11, and other chambers. Further, a handle 12 for transportation is integrally provided. Furthermore, various parts such as wheels 13, casters 14, and a bail 16 for braking the cord winding device are attached. The collection/dust removal device storage chamber 9 is provided with an outlet 17 that is open to the outside so that the dust collector 4 can be attached and detached.
A front lid device 6 is attached so as to be openable and closable. 4. The dust collection device is constructed as follows.

A fine filter 19 for dust filtration is integrally provided at the bottom of a box-shaped dust collection case 18 made of synthetic resin or the like. The fine filters 19 are divided into left and right parts at the center, and between the fine filters 19, a striking plate 20 is fixedly fixed by a screw 21 and a screw 22. That is, fine filters 19 are arranged on both sides of the striking plate 20.

Further, the fine filter 19 is formed by bending a filter material such as a nonwoven fabric or cloth into a wave shape, and the striking plate 20 is arranged without protruding beyond the height H of the wave shape. This striking plate 20 is configured to operate by engaging with a cam body of a dust removal device 5 to be described later, and to apply a strong blow to a receiving body 23 formed integrally with the dust collecting case 18 to generate vibration. ing.

Reference numeral 28 denotes a coarse filter, which is a mesh filter made of nylon, polyethylene, etc., and is formed by integrally joining the vibration receiving body 29 and the vibration transmission plate 30.

The vibration receiver 29 of the coarse filter 28 is fitted and held in the receiver 23 of the dust collection case 18 described above, and the receiver 23 is
The vibration energy generated by the impact by the impact plate 20 is sensed and transmitted through the coarse filter 30.
28 serves to transmit vibrations to the entire surface.

31 is a paper bag filter made of a filter material such as Japanese paper or nonwoven fabric.

The paper bag filter 31 is manufactured through the steps shown in FIG. First, punch a hole in a sheet of standard length, then glue it together into a cylindrical shape, then glue the inlet into the hole, and then,
Make a paper bag filter by folding and gluing both ends of the cylindrical tube. At this time, in the step of punching out the hole 76 and pasting it into a cylindrical shape, if the hole 76 is completely punched out, the 14th
As shown in the figure, the punching slag 75 gets mixed into the gluing margin 77 of the cylindrical joining part, and the gluing is insufficient, or the product is produced with the slag 75 still inside the bag, so the holes 76 are completely sealed. Do not punch out the paper bag filter 31, but attach the upper part of the mounting plate of the paper bag filter 31, the clamp 52 side when setting it to the main body, as shown in Fig. 13.

When the remaining allowance is 3mm to 30mm, if it is less than 3mm,
The position is not stable, and when fitting the mounting plate 32 into the hole 76 in the fourth step in FIG. 12, the mounting plate 32 wanders near the hole 76, so they are fitted at the same time. Further, if the length is 30 mm or more, the current changing plate 79 of the front cover 48 cannot push it completely, causing a problem of deforming the mounting plate 32.

Note that the uncut portion of the backflow prevention plate 78 is the paper bag filter 3.
It is convenient for manufacturing to shift the paper bag filter 31 by 90 degrees from the upper side of the paper bag filter 31 as a reference, and to position it on the front side when viewed from the flow direction of the manufacturing process of the paper bag filter 31.

In this embodiment, the rotational power of the cord winding device 62 also serves as a driving source for the dust removal device 5 of each filter.

The present invention has the above configuration, and its functions and effects will now be described in detail.

The vacuum cleaner of the present invention is usually equipped with a 31 paper bag filter for cleaning.

The 31 paper bag filter is installed on the 25 guide boss of the 18 dust collection case and the 32 mounting plate of the 31 paper bag filter.
When you operate a vacuum cleaner with paper bag filter 31 set in this way, which is set by aligning the 4 guide holes or placing it on the support plate 27, the dust (garbage) inhaled from the suction port 50 will be sucked into the paper bag filter 31. The air flows in from the opening 33 and enters the bag of the paper bag filter 31, where only dirt is filtered out, and the clean air flow passes through the coarse filter 28 and the fine filter 19, and then enters the exhaust chamber 11 of the main body case 1. As described above, the filtration system for the dust discharged from the exhaust port through the paper bag filter 31. Due to the structure of a three-stage filter consisting of a coarse filter 28 and a fine filter 19, there may be cases where all the dust is not completely filtered out by the first stage paper bag filter 31, or when the paper bag filter 31 is damaged. Even if there is dust that passes through the paper bag filter 31 for various reasons, it is filtered by the second-stage coarse filter 28 or the third-stage fine filter 19, so that it is discharged from the exhaust port of the main body case 1. The air flow is much cleaner than that of conventional vacuum cleaners, and it greatly contributes to sanitizing the exhaust air.

Next, when the filtered dirt adheres to the surface of the paper bag filter 31 or the fine filter 19, the ventilation resistance at that part gradually increases, and the suction power of the vacuum cleaner decreases, making the vacuum cleaner less functional. However, in the vacuum cleaner of the present invention, when the cord 62 is pulled out at the beginning of cleaning, the cord reel 62 rotates, and in conjunction with this rotational force, the face gear 37 rotates. Dust removal gear 3
9 is rotated, the dust removal plate 40 presses and slides on the back surface of the fine filter 19, vibrates, and first removes dust attached to the surface of the fine filter 19. At the same time, since the coupling gear 42 is rotating, the cam 46 operates the striking body 20 and the receiving body 23 is vibrated by impact, thereby transmitting the vibration to the entire surface of the dust collection case 18. At the same time, the vibration transmitting plate 3 passes through the vibration receiving body 29 of the coarse filter 28 fitted to the receiving body 19.
The vibration will also be transmitted to 0.

In other words, the entire surface of the dust collection case 18 and the coarse filter 28 that are in contact with the paper bag filter 31 is vibrated, and this vibration is transmitted to the back surface of the paper bag filter 31, so that the inner surface of the paper bag filter 31 is vibrated. The attached dust is also removed by the transmitted vibration.

Further, when the cord 62 is wrapped around the body after cleaning, the fine filter 19 is removed by the dust removal plate 40 attached to the dust removal gear 39. However, the cam 46 is Since the impact body 20 is not rotated and the impact body 20 is not operated, the dust removal operation of the paper bag filter 31 is not performed.

As described above, in the vacuum cleaner of the present invention, the dust attached to each filter is automatically removed in conjunction with the operation of inserting and removing the power cord 62 at the beginning and end of cleaning, so that the suction force is always strong. It is something that can be sustained.

However, if the paper bag filter 31 eventually becomes full of dust, the suction power will not recover no matter how much dust removal work is performed.

At this time, open the front cover 48. At this time, the backflow preventer 78 is in close contact with the upper part of the current transformation plate 79 of the front lid 48, so even if the front lid 48 is opened, it can be opened without drawing out dirt and contaminating the surrounding area. After the front cover is fully opened, the backflow preventer closes the opening and prevents the dirt from coming out.

First, after folding the sealing plate 35 part of the paper bag filter 31 and sealing the suction port 33 with a lid, hold the mounting plate 32 part and place the paper bag filter 31 inside the dust collection case 18 with the paper bag filter 31 still set in the main case 1. If the paper bag filter 31 is pulled out and the garbage accumulated therein is thrown away into a trash can or the like, the garbage disposal operation is completed, making it possible to dispose of garbage very easily.

Another feature of the present invention is that the paper bag filter 31 can be disposed of as follows. That is, after opening the front lid 48 and closing the inlet 32 with the seal plate 35, pull out the dust collection case 18 from the main body case 1 with the paper bag filter 31 still set, and take it to a trash can or the like. Then, by turning the dust collection case 18 upside down and dropping the paper bag filter 31 into the trash can, the garbage can be thrown away together with the paper bag filter 31. Usually, the former method is used to remove the paper bag filter 31 without removing the dust collection case 18 from the main case 1.
The method of pulling out the dust and disposing of the garbage as it is is fully functional and makes it easy to dispose of the garbage, but for example, if a large amount of heavy garbage such as metal pieces, earth and sand is sucked in,
If the paper bag filter 31 cannot withstand the weight of the garbage and if you pull it out alone, it may break and the garbage will scatter, or if the paper bag filter 31 breaks during suction due to some kind of trouble, If you try to dispose of garbage by pulling out the paper bag filter 31, the garbage will scatter outside and become unsanitary. This makes it convenient and hygienic to dispose of trash.

After the garbage disposal is finished in this way, the pocket lid 56
If you open it, take out the refill paper bag filter 31, and set it in the dust collection case 18, you can clean it again.

Next, if there is no paper bag filter 31 to replenish due to forgetting to buy one or the like, the vacuum cleaner of the present invention can function as a vacuum cleaner without setting the paper bag filter 31.

In other words, if the paper bag filter 31 is not set,
The coarse filter 28 filters out relatively large debris such as cotton dust and paper waste, and the fine filter 19 filters fine debris such as sand and dirt, similar to a conventional vacuum cleaner. It is.

To dispose of the garbage at this time, you can open the front lid 49, pull out the dust collection case 18 from the main case 1, take it to a trash can, etc., and throw away the garbage accumulated inside the dust collection case 18. It is possible.

According to this embodiment, there are the following effects.

1. When manufacturing paper bag filters, punching slag will not get mixed into the glue margin and produce defective products, improving productivity.

2. When a paper bag is set to suck up dust, the backflow preventer covers the top of the current variable plate, so dirt does not accumulate on the top of the current variable plate, so even if you open the front cover, you do not have to take out the dust, making it hygienic. Can dispose of garbage.

3. When you open the front cover, the backflow preventer will fall down under its own weight,
Close the suction port to prevent dirt from spilling out.

According to the present invention, there is an effect that productivity is excellent and furthermore, garbage can be disposed of hygienically during use.
