Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) The present invention relates to a vacuum cleaner in which a bag-shaped dust collection filter is removably installed in the dust collection chamber. This invention relates to a structure that allows a dust collection filter to be easily attached to a vehicle without providing an opening frame or the like.

(Prior Art) Conventionally, in this type of vacuum cleaner, a bag-shaped dust collection filter is detachably installed in the dust collection chamber, and dust is stored in the dust collection filter. To make it easier and more reliable,
For example, as described in Japanese Utility Model Publication No. 45-26455, a rigid mouth frame is glued to the opening end of a dust collection filter, and this mouth frame is attached to and removed from a holding plate provided inside the dust collection chamber. is taken.

Alternatively, as described in Utility Model Publication No. 45-36399, the dust collection filter is not provided with an opening frame,
There is also known a structure in which the open end of the dust filter is placed around the suction pipe and a retaining ring made of rubber or the like is attached to elastically retain the dust filter.

(Problems to be solved by the invention) In the above conventional structure, in addition to the dust collection filter made of a paper bag, it is necessary to use members such as a spout frame or an elastic ring made of cardboard, etc., resulting in high cost. I have a problem.

Furthermore, in the structure described in Japanese Utility Model Publication No. 45-36399, it is necessary to attach the retaining ring while the open end of the dust collecting filter is placed around the suction pipe. I had a problem that took a lot of time.

Furthermore, as described in Japanese Utility Model Publication No. 45-26455, the structure in which the mouth frame is glued to the dust collection filter lacks compatibility, and the expansion and contraction rate depending on the properties of the adhesive, adhesive strength, adhesive position, and season. Because there are many unstable factors such as changes in There was a problem in making the mouth frame smaller.

This invention was created in view of the above problems.
There are fewer parts to hold the dust collection filter in the dust collection chamber, making it cheaper, and the dust collection filter can be easily attached and removed, and it can be held securely. It is an object of the present invention to provide a vacuum cleaner which has a small amount of noise and has flexibility in terms of its size, etc.

Next, the operation of this embodiment will be explained.

The dust filter 51 is installed with the lid 41 open. At this time, as shown in FIG. 2, due to the bias of the spring 33, the suction port member 31 is tilted in a direction in which the dust collection chamber 3 side is separated from the fitting recess 25. Then, the open end 52 of the dust collecting filter 51 is placed over the end of the suction port member 31 on the dust collection chamber 3 side, that is, the mounting wall, and then the lid 41 is closed. To close the lid 41, first engage the engaging protrusion 45 with the engaging stepped portion 24 of the cleaner body 1, and then rotate the lid 41 in the clockwise direction in the figure around its front edge. let Then, the engaging claw portion 44 of the clamp 43 swings, causing the vacuum cleaner body 1
The lid body 41 is engaged with the engagement receiving portion 23 of the lid body 41.
The rear edges of both sides are the fitting step portions 22 of the vacuum cleaner main body 1.
The lid body 41 is attached to the vacuum cleaner body 1 by being fitted into the vacuum cleaner body 1.

In this state, open end 5 of dust collecting filter 51
2, over the entire circumference, the outer peripheral surface of the suction port member 31, the inner peripheral surface of the fitting recess 25 as the main body side clamping part of the vacuum cleaner main body 1, and the contact part as the lid body side clamping part of the lid body 41. The lower surface of the contact piece 46 is airtightly sandwiched,
A dust collection filter 51 is held within the dust collection chamber 3.

During cleaning, the user grips the handle 9 and slides the suction port member 31 on the surface to be cleaned.
Then, by driving the electric blower 11, the dust sucked in from the suction port member 31 is transferred to the dust collection filter 5.
It is stored in 1. Note that at this time, the valve body 35 of the suction port member 31 opens due to wind pressure.

When a certain amount of dust has accumulated in the dust collecting filter 51, the dust collecting filter 51 is discarded and replaced with a new dust collecting filter 51. To do this, first open the lid 41. To open the lid 41, first push the clamp 43 to disengage the locking claw portion 44 from the engagement receiving portion 23 of the cleaner body 1, and then push the engagement protrusion 45 of the lid 41 onto the cleaner body 1. It comes off from the engagement stepped portion 24. When the lid 41 is opened in this manner, the suction port member 31 rotates due to the bias of the spring 33, and the dust collection chamber 3 side thereof moves toward the opening 21. In this state, the cleaner body 1 and the lid 41 are not in contact with the open end 52 of the dust collection filter 51, so
By simply pinching the open end 52 to close it and pulling the dust collecting filter 51, the open end 52 comes out from the suction port member 31, and the dust collecting filter 51 comes off.

Next, a new dust collection filter 51 is installed as described above, and the lid body 41 is closed.

Such replacement of the dust collection filter 51 is performed in the first
As shown in the figure, the vacuum cleaner body 1 can be placed with its bottom side facing down, but it can also be carried out with the vacuum cleaner body 1 placed upright with its rear side facing down as shown in Figure 2. You can also do that. If the work is carried out in this upright position, dust will not spill out from the open end 52, especially when removing the dust collecting filter 51 where dust has accumulated.

According to the above configuration, the opening end 52 of the dust collecting filter 51 is not provided with a mouth frame, and there is no need for a retaining ring or the like for holding the opening end 52 on the suction port member 31. Therefore, there is no need to provide a holding plate or the like for holding the mouth frame in the dust collection chamber 3, and there is no need to attach the mouth frame to the dust collection filter 51 during manufacturing, thereby providing an inexpensive vacuum cleaner. At the same time, it is possible to reduce the incidence of defective products. In the small hand-held vacuum cleaner shown in the above embodiment, if the mouth frame is provided on the dust collection filter 51, the mouth frame must be small, and the work of gluing the mouth frame during manufacturing is required. This makes it difficult to attach the dust filter 51 during use, so not providing the dust filter 51 with a mouth frame as described above is particularly effective for small vacuum cleaners.

Further, as described above, the dust collecting filter 51 can be removed by simply placing the open end 52 over the suction port member 31 and then closing the lid 41 without attaching a retaining ring to the open end 52 of the dust collecting filter 51. 51
It can be easily installed and does not require any effort.
In the attached state, the suction port member 31, the cleaner body 1, and the lid 41 are sandwiched around the entire circumference of the open end 52 of the dust collecting filter 51, so that the dust collecting filter 51 is securely attached. is maintained. Further, when removing the dust collecting filter 51, it is only necessary to open the lid body 41 and pull the dust collecting filter 51, and the operation is easy.

Furthermore, as described above, since the opening end 52 of the dust collecting filter 51 is held between the suction port member 31, the cleaner body 1, and the lid 41,
The vacuum cleaner has a large tolerance for differences in the opening area of the opening end portion 52 and has excellent compatibility.

Note that even if the spring 33 that biases the suction port member 31 is not provided, if the front end of the upper surface of the suction port member 31 is pressed, the suction port member 31 will rotate, so the dust collection filter 51 can of course be attached and removed. Ru. However, when the structure is such that the spring 33 is not provided, there is a slight problem in stability because the suction port member 31 located above must be pushed, especially when the vacuum cleaner body 1 is placed upright and the attachment/detachment work is performed. . On the other hand, if the structure is such that the suction port member 31 is biased by the spring 33 as in the above embodiment, the suction port member 31 will automatically rotate in the direction of the opening 21 when the lid body 41 is opened. The dust collecting filter 51 can be attached and detached easily and visually, and the work can be carried out in a stable state.

Further, the suction port member 31 may be detachably attached to the vacuum cleaner main body 1, for example, but as in the above embodiment,
If the suction port member 31 is rotatably supported on the cleaner body 1, it is not necessary to attach and detach the suction port member 31, and the dust collection filter 51 can be attached and detached more easily.

[Effect of idea]

According to the present invention, the opening end of the bag-shaped dust collection filter is removably covered with the mounting wall of the suction port member, and the mounting wall of the suction port member and the main body side clamping portion of the vacuum cleaner main body are connected to each other. By clamping and holding the opening with the lid body-side clamping part of the lid body that opens and closes the opening,
You can easily attach and detach the dust filter without attaching a retaining ring to the opening end, and
This dust collection filter is securely held in the dust collection chamber, and there is no need to glue a mouth frame to the dust collection filter or provide a holding plate to hold this mouth frame, reducing the incidence of defective products. In addition to being able to produce a vacuum cleaner that is both efficient and inexpensive, this dust collection filter can be installed even if there is a certain degree of difference in the opening area of the opening end of the dust collection filter, and the volume of the dust collection chamber is small. A dust collection filter can also be easily installed.
