Abstract

PROBLEM TO BE SOLVED: To raise durability of a filter by a method wherein, in that which shakes off dust stuck to each fold of a formed filter, a material harder than a filter material is used, and a wavy diaphragm is attached to the formed filter to be knocked with a duster rod conforming to an irregularity of each fold. SOLUTION: Though dust-containing air sucked by suction force of a blower is filtered with a formed filter 6, the formed filter is constituted in a box type by attaching many folds 6F crosswise in a filter fitting frame. In this case, duster rods 10X-12X are protruded from respective tip front parts of duster plates 10S-12S fitted to front surfaces of respective gears 10-12 rotates by linking with a motor. Further, a wavy diaphragm 7 is attached to an inside surface of each fold 6F of the formed filter 6. The diaphragm 7 is formed wherein a comparatively hard material such as a plastic board or the like is used, and formed so that the irregularity of the waveform continues crosswise conforming to the irregularity of each fold 6F. Thereby, durability of the filter 6 is raised.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filter for removing dust (dust) adhering to a formed filter used in a dust collector or a vacuum cleaner.

[0002]

2. Description of the Related Art Conventionally, there are various types of dust removers for removing dust adhering to a filter, such as a pulsedet type, a backwash type, and a vibration type. No.-65720 and 62-561
As can be seen in Japanese Patent Publication No. 22, a vibrating dust remover that applies a vibration to a filter to wipe off the filter is relatively simple in structure and can be used easily, and thus is widely used in small dust collectors and vacuum cleaners.

[0003]

However, all of the above-mentioned vibration type dust removers hit each fold of the filter by rotating a fly stick (vibrator), and dust attached by the vibration at the time of hitting. There are various problems that the filter cannot be sufficiently vibrated as a whole and that the filter is damaged because it is configured to be removed.

That is, since the filter itself is made of a relatively soft material, when the individual folds are vibrated by hitting with a pounding stick, the vibration (shock) occurs only in the individual folds. However, the generated vibrations are absorbed into the folds by the buffering action of the filter material, so that the rate of transmission of the vibrations to other adjacent folds is extremely small, and the other folds are large. Since there is no vibration, there is a problem that a sufficient vibration force, that is, a sufficient removal force cannot be obtained.

Furthermore, since the dust is repeatedly removed by repeatedly hitting each fold with a fly stick, the surface of the soft filter may be cut or worn out immediately, resulting in a hole in the filter surface.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a filter capable of exhibiting an excellent dust removing effect by vibrating a filter more greatly by using a flycatcher rod and preventing the filter from being easily damaged by repeatedly hitting the flycatcher rod. It is.

[0007]

Means taken by the present invention to solve the above-mentioned technical problems are as follows.

[0008] A dust removing device for a filter, wherein each of the folds of a formed filter in which peaks and valleys are alternately successively hit is vibrated by hitting the folds with a fly bar, thereby removing dust adhering to each fold.

(1) On the surface of the formed filter hit by the above-mentioned brush bar, a corrugated vibrating plate having a cross section bent substantially in a corrugated shape according to the unevenness of each continuous fold using a material harder than the filter material is used. Installing. (Claim 1)

(2) The corrugated diaphragm to be mounted on the surface of the forming filter is divided into a plurality of blocks, and these blocks are mounted side by side with a slight space between adjacent blocks. (Claim 2)

(3) The depth of the waveform of the corrugated diaphragm is made smaller than the fold depth of the peaks and valleys forming each fold of the formed filter, and a space is provided between each fold and the corrugated diaphragm. thing. (Claim 3)

(4) The corrugated diaphragm is made of a relatively hard material such as metal or plastic.
(Claim 4)

According to the first aspect of the present invention, since the diaphragm is made of a harder material than the molded filter, the fly stick is more impacted on the corrugated diaphragm. Can generate large vibrations
In addition, compared to the case where the individual folds of the formed filter are vibrated, since the corrugated diaphragm is constituted by a plurality of corrugated portions, the hatching bar hits one corrugated portion of the corrugated diaphragm. At the same time, the vibration spreads to other waveform portions, so that the formed filter can be vibrated over a wide range, and the filter can be vibrated over a wide range for each waveform. It is possible to increase the surplus effect and exhibit an excellent dust removing action.

According to the means according to the second aspect described in the above (2), if the area of the corrugated diaphragm is made large and the number of corrugations is increased, the vibration is attenuated on the way and reaches every corner of the diaphragm (filter). In some cases, vibration cannot be transmitted sufficiently.However, the waveform diaphragm is divided into a plurality of blocks. This makes it possible to reliably vibrate the corrugated diaphragm in each block unit and to vibrate the filter to which it is attached more strongly, thereby exhibiting an excellent dust removing effect.

According to the third aspect of the present invention, since a space (space) is provided between each fold of the formed filter and the corrugated diaphragm, each fold of the formed filter can be removed. The purified air flow filtered by passing through the space can be smoothly suctioned to the blower side through this space, and the corrugated diaphragm supports to make sure that the folds of the forming filter are pressed against each other by the pressure of the inflow air flow. In order to prevent this, it is possible to secure a passage for the purified airflow.

According to the fourth aspect of the present invention, since the corrugated diaphragm is made of a relatively hard material such as metal or plastic, the impact of hitting with a fly stick is provided. In addition to protecting the flexible filter from vibrations, the vibrations of the fly stick can be reliably transmitted to the filter side to achieve an excellent dust removing effect.

As described above, the above (1) to (1)
By solving the above technical problem by means of (4),
The problem of the conventional technique can be solved.
