Description

[Detailed explanation of the idea] This invention relates to a vacuum cleaner.

In vacuum cleaners, a filter is generally provided at the exhaust port to capture fine dust contained in the exhaust air or to disperse and exhaust the exhaust air.

As a means to hold the filter, a filter made of urethane or the like is glued to the inner surface of the exhaust port formed in the main body case that houses the electric blower, or to the inner surface of the exhaust grate of the exhaust cover attached to the main body case. cannot replace a clogged filter.

In addition, when attaching the exhaust cover to the main body case, the filter is held between the two, but since the filter is held between hard members, it tends to deform, resulting in a gap. It has the disadvantage that the exhaust air is emitted along with fine dust.

Also, for example, Utility Model Application Publication No. 49-61853 and Utility Model Application Publication No. 4
As described in Publication No. 9-61855, an exhaust filter having a frame around the exhaust cover is fitted to the exhaust cover to prevent fine dust from being discharged from between the exhaust filter and the exhaust cover. However, in all of these, the frame body is not elastic and the pressure of the exhaust air is quite strong, so when used for a long time, the outer circumference of the exhaust filter deforms and fine dust is discharged.

This idea was devised in view of these points, and was designed to make it easier to clean and replace the filter on the exhaust side, and to connect the main body case and the exhaust cover without creating any gaps. The purpose is to

This idea makes it easy to clean or replace the filter by removably attaching the filter to the exhaust cover that opens and closes the exhaust port of the main body case, and when the exhaust port of the main case is closed with the exhaust cover, The filter of the exhaust cover is elastically joined to the soft member provided at least around the exhaust port of the main body case, thus preventing the soft member and the filter from deforming, preventing the generation of gaps, and releasing fine dust. It is designed to prevent this from happening.

A first embodiment of this invention will be explained based on FIGS. 1 to 4.

Reference numeral 1 denotes a main body case that houses an electric blower 2 and a cord reel 3. A dust case 5 that houses a filter 4 is detachably connected to this main body case 1 by a clamp 6.

The back of the main body case 1 is formed with an exhaust grate 7 which is an exhaust port, and on the inner surface of the exhaust grate 7 is a filter 8 made of urethane or the like with a coarse mesh whose main purpose is to muffle noise rather than capture fine dust. Further, a soft member 9 made of urethane or the like is attached to the circumference of the exhaust grid 7 while being fitted into the annular rib 10 .

Then, an exhaust cover 12 with an exhaust grate 11 formed thereon is provided.

A soft filter 13 made of urethane or the like with a dense mesh is provided along the inner surface of the exhaust grid 11 for the purpose of capturing fine dust.

This exhaust cover 12 has a hinge pin 14 protruding inward on its lower edge that is fitted into a bearing 15 formed on the back surface of the main body case 1, and a pawl 16 formed on the upper edge of the main body case 1. It is connected to the main body case 1 by resiliently engaging with a locking hole 17 formed on the back surface of the main body case 1.

Further, a handle 18 is formed on the upper surface of the exhaust cover 12.

A hook 19 is formed on the inner surface of the exhaust gas M12 to pierce the filter 13 and hold the filter 13 in a detachable manner.

In such a configuration, the exhaust air is exhausted from the filter 8, the exhaust grid 7, the filter 13, and the exhaust grid 11 in this order.

When the exhaust lid 12 is closed, the periphery of the filter 13 and the soft member 9 are elastically pressed against each other, and the two are less likely to be deformed due to permanent deformation and less likely to form a gap.

Moreover, when the exhaust filter 13 is pressed toward the exhaust cover 12 side by the wind pressure of the exhaust air during cleaning and tries to shrink in the thickness direction, the soft member 9 causes the exhaust filter 13 to close due to its elasticity.
The exhaust filter 13 and the soft member 9 always maintain their close contact with each other.

Therefore, the exhaust air always passes through the filter 13, and fine dust is ultimately captured by the filter 13.

The filter 13 can be separated from the exhaust gas i12 by removing the claw 16 of the exhaust cover 12 from the main body case 1, and can be replaced or dusted.

Next, a second embodiment of this invention will be explained based on FIG.

The same parts as in the previous embodiment are designated by the same reference numerals, and the description thereof will be omitted.

In this embodiment, an annular rib 20 is formed around the exhaust grid 7 of the main body case 1, and a filter 21, which is a soft member that covers the entire surface of the exhaust grid 7, is fitted into the annular rib 20. The peripheral edges of the filter 22 supported by M12 hooks 19 are joined together while being elastically deformed.

Therefore, fine dust is captured by the two filters 21 and 22, and the effect of purifying the exhaust air is promoted.

Other operations are similar to those in the previous embodiment. Since this device is configured as described above, the exhaust filter can be replaced or dust removed by opening the exhaust cover.
The exhaust cover is opened and closed many times, but by elastically bonding the soft member of the main body case and the filter detachably attached to the inner surface of the exhaust cover, gaps are generated due to deformation between the soft member and the filter. In addition, even if the thickness of the exhaust filter changes due to compressive force from the exhaust air, the soft member follows the change in thickness due to its elasticity, so that the adhesion between the two is always maintained. This has the effect of being able to effectively trap fine dust contained in the wind.
