Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a vacuum cleaner, and particularly to a vacuum cleaner with excellent productivity and ease of handling.

[Prior art]

Conventionally, the handle for transporting the main body of a vacuum cleaner can be roughly divided into a fixed handle, which is either integrated with the main body case or attached as a separate part, and a handle that rotates with one end of the handle fixed on a shaft. There is a rotating handle that can be rotated freely, but while the former has fewer parts and is easier to assemble, the handle protrudes from the main body of the vacuum cleaner, or the main body case has to be hollowed out in order to install the handle. However, it has disadvantages such as a decrease in design, and the fact that the main body is stiff due to the handle, making it difficult to handle.

Secondly, since the latter has a rotatable handle, it can be stored in a part of the main body when the handle is not in use, giving it an excellent design, and it also requires less storage space and is smaller. In short, it is extremely easy to handle.

However, compared to a fixed handle, in order to rotate it,
It has drawbacks such as an increased number of parts and a time-consuming assembly.

[Purpose of the invention]

In view of the above points, the present invention focuses on the rotatable lid body that opens and opens the opening of the passenger compartment among other mechanical parts constituting the vacuum cleaner, and the advantages of the rotary handle. The aim is to improve assembly efficiency, which is a drawback, while maintaining the same characteristics.

[Summary of the invention]

The key points are that a part of the vacuum cleaner case that houses the motor, cord reel, etc. is provided with an opening where the dust collection means can be detachably attached, and a rotatable lid body that can open and close the opening. In the vacuum cleaner which has a rotatable rotating handle provided on the case of the main body of the vacuum cleaner, the rotating shaft of the lid body and the rotating shaft of the rotating handle are configured to be the same.

At this time, the paper bag filter 22 is set so as to be airtightly held within the dust collection case 9 by the action of the connection backing 23 provided at the connection port 21 portion.

This paper bag filter 22 has a system in which the dust is introduced into the bag through the intake port 26, filtered by the bag-like filtration part 25, and accumulated inside the bag, and then taken out as is and thrown away together with the bag. This is a filter.

Reference numeral 42 denotes a damping plate formed of a substantially U-shaped flat plate arranged so as to apply impact vibration to the fruit case 9. This dust removal plate 42 is held by a partition plate 43, and transmits the rotation of the cord reel 4 to a reel gear 44, a reduction gear 45, and a dust removal gear 46, so that the dust removal plate 42 is connected to a tension spring 4.
The spring force of 7 is configured to collide with the protrusions 48 and 49 of the dust collection case 9, and apply a strong impact force to the entire surface of the dust collection case, especially when pulling out the power cord 3. There is. At this time, the protrusion 48 of the dust collection case 9,
49, the groove inside the case has a side surface 32 of the cage 28.
Since the bosses 50 and 51 provided in the cage 2 are in contact with each other, the cage 2
8 is also configured to apply a strong impact.

The above is an explanation of the structure of one embodiment of the vacuum cleaner according to the present invention.Next, the functions and effects thereof will be described.The vacuum cleaner according to the present invention usually has the following structure as shown in FIG.
The dust collection case 9 and the paper bag filter 22 are used in combination. When motor 2 is operated in this state, the suction port,
Through an extension pipe and a hose (not shown), a flow of air containing air flows into the paper bag filter 22 from a suction port 19 provided in the lid 14 as shown by the arrow. The garbage flowing in here is filtered by the bag-like filtration part 25, and then the dust collection case 9
Since it is further filtered in the slow-returning part 11, the final collection efficiency of the inhaled dust is 99 to 99.75%, showing excellent performance. If cleaning is continued in this manner, the suction strength will gradually decrease as the airflow resistance increases as dirt adheres to each filter part (9), but the vacuum cleaner of this embodiment , by using the pulling and retracting action of the power cord during the cleaning operation.
Since the structure is configured to dynamically remove dust adhering to each filtration section, the air permeability of each filtration section can be restored and cleaning can be continued efficiently and with strong suction power again. To explain this point in more detail, Figure 6 shows the power cord 3
' As the power cord 3 is pulled out, the rotational force of the cord reel 40 is transmitted to the dust removal gear 4.
6 rotates in the direction of the arrow. The dust removal gear 46 has a blade 52 that horizontally pulls the dust removal plate 42 away.
7 (Fig. 6 (b)) and further rotate the dust removal gear 46, the blade 52 comes off and the dust removal plate 42 collides with the protrusion 48 of the dust collection case 9 (Fig. 6 (b)). (
B)). At this time, a strong impact is also applied to the boss 50 of the cage 28, and the various boxes are removed. Here, 5
3.54 are bosses for holding the dust removal plate 42 on the partition plate 43, and 55 are bosses for fixing the tension spring 47 to the partition (10) plate 43.

Next, FIG. 7 shows a case where the power cord 3 is wound up.

To prevent entrainment, the dust removal gear 46 rotates in the direction of the arrow, and the dust removal plate 42 rotates while extending the tension spring 47 using the outer periphery of the protrusion 48 of the dust collection case 9 as a fulcrum.
(b)) When the dust removal gear 46 further rotates, the blade 52 comes off from the dust removal plate 42 and rotates under the force of the tension spring 47, so that the end portion 56 of the dust removal plate 42 collides with the protrusion 49. At the same time, an impact is applied to the boss 51 of the cage 28, and the dust is removed from each filter surface.

When the inside of the paper bag filter 22 is full of dust after continuing cleaning as described above, when the clamping device is operated, as shown in FIG. Due to the spring force, the paper bag filter 22 protrudes upward from the opening 16 of the dust collection case 9. Therefore, in this state, the mounting plate 27 of the paper bag filter 22 is located immediately above the dust collection case 9 (1
1) Since it is in a position where it can be held, it can be easily taken out.

On the other hand, when moving the main body during cleaning or after cleaning, raise the rotating handle 8 and carry it, and when storing the main body, fold down the handle to prevent the handle from getting tangled in hoses, etc. It is easy to handle and can be conveniently stored even in narrow storage spaces.

In this example, the lid and rotating handle are attached to the top of the main body, but a lid with an opening on the side as shown in Fig. 8 (b) can also have a similar configuration. can do. In this case, when compared to the conventional example in Fig. 8 (a), not only is the main body smaller, but also there is no nozzle and ease of handling is improved when considering the operation of attaching and detaching the hose to the suction port. It can be easily thought of.

Further, the dust collecting means may not be constructed in the case shape as in this embodiment, but may instead be a paper bag made of filter paper formed into a bag shape.

Therefore, according to this embodiment, (12) (1) By configuring the rotating shaft of the lid body for opening and closing the passenger compartment opening and the rotating handle to be the same, the rotating shaft and the bearing portion are shared. As a result, the number of required parts can be reduced.

(2) Very easy to assemble because the lid, one-knob needle, and main case are assembled by inserting only one rotation shaft.

(3) Since only one hinge is required for each of the lid and rotating handle, the hinge does not protrude from the main body in two places, and the main body of the vacuum cleaner does not become large, making it easy to handle. Not only that, but also the appearance design is good.

〔Effect of the invention〕

According to the present invention, it is possible to provide a vacuum cleaner with excellent productivity and ease of handling.
