Description

Automatic dust collection device for vacuum cleaners {AUTOMATIC DUST COLLECTING DEVICE OF VACUUM CLEANER}

The present invention relates to a vacuum cleaner, and more particularly, to an automatic dust collecting device of a vacuum cleaner for automatically collecting dust into a dust collecting box after cleaning is completed.

Generally, the vacuum cleaner is mainly used for cleaning corners and other places where general brooms or other cleaning tools are difficult to clean in a house, a car, or other places. It is a device to remove dust.

Such a conventional cleaner divides the inside of the casing 100 of the vacuum cleaner by the separating plate 101 as shown in FIG. 1, and generates a suction force for collecting dust on one side and a dust collecting part for collecting dust on one side. It consists of a suction force generator.

The dust collector separates the suction pipe 111 for sucking air containing dust from the outside, the suction port 112 connected to the suction pipe 111 and communicates with the air including dust sucked through the suction port 112. To the upper side is composed of a filter member 113 and a dust collecting box 114 for collecting dust separated by the filter member on the lower side.

An air passage 115 is formed to communicate with the inside of the filter member 113 to transfer air to the suction force generating unit, and the dust collected on the upper side of the dust collector 114 flows to the bottom or the bottom. An inclined plate 114a is provided to prevent the accumulated dust from scattering.

The suction force generating unit may penetrate through the separation plate 101 and suck the air separated from the filter member 113 through the air passage 115 and through the suction hole 102. One side wall of the casing 100 is formed with a blowing fan 120 sealed to the separation plate 101 and a discharge hole 103 for discharging the air sucked from the blowing fan 120 to transmit suction force. .

By such a configuration, the conventional vacuum cleaner filters the air containing dust sucked through the suction port 112 connected to the suction pipe 111 by the filter member 113 and the remaining dust is inclined plate formed at the lower side. It flows down along 114a and is collected in the dust collecting box 114, and the filtered air passes through the suction hole 102 of the separation plate 101 via an air passage 115 formed in communication with the inside of the filter. It is discharged to the outlet 121 through the blowing fan 120.

However, the bagless vacuum cleaner should not reduce the suction power even when the dust is not emptied. However, in the case of a combination type using a four-filter type filter on the air flow path, the suction resistance decreases as the flow resistance increases as the dust is still sucked. If you continue to operate with the dust filled, the probability of re-contaminating the house is increased, and if the filter capacity is increased to reduce the trouble of emptying the dust collector often, the cleaner body becomes large.

According to the present invention devised to solve the above-mentioned problems, the automatic dust collection apparatus for automatically collecting the dust collected in the dust collector to the outside of the cleaner body after cleaning using a bagless type vacuum cleaner An object of the present invention is to provide an automatic dust collecting device of a vacuum cleaner that does not need to be separated frequently to prevent re-contamination of the flow path resistance and the collecting guide part generated from the filter member.

The pair of stop projections 18 are provided on the separating plate 2 and the dust collecting unit rear wall 16 formed on the inner wall of the dust collecting unit.

The operation of the vacuum cleaner to which the automatic dust collecting device according to the present invention is applied will now be described. First, in the cleaning mode, as shown in Fig. 2, the flow path switching member 3a of the flow path switching valve 3 is raised. When the blower fan 20 is operated while the first common air path 17a communicates with the suction hole 4 through the second common air path 17b, the suction force of the blower fan 20 is reduced by the suction hole 4. ), The common air flow path 17b and the first common air flow path 17a act on the cleaning intake port 11 so that air containing dust is sucked into the dust collecting chamber C through the cleaning intake port 11, Dust contained in the air sucked by the filter member 13 installed in the dust collecting chamber C is collected. The collected dust flows down the inclined plate 15 formed at the lower side of the filter member 13 to be collected in the dust collector 14, and the filtered air is first and second common air through the interior of the filter member 13. The cleaning mode is performed while being sucked into the suction hole 4 of the separation plate 2 through the flow paths 17a and 17b and discharged through the blower fan 20 to the discharge port 5.

In the dust collection mode, as shown in Fig. 8, the cleaning inlet 11 is placed on the dust collecting box 31 while the vacuum cleaner having completed the cleaning operation as described above is placed on the dust collecting box 30. When the inlet for the collection 33 is in communication with the dust collecting inlet 7 and the dust collecting air outlet 36 of the base 32, the opening and closing member 6a of the intake opening and closing valve 6 for collecting dust Is pushed up by the opening projection 37 to open the dust collecting inlet 7 and the second common air passage 17b and the dust collecting air outlet 36 communicate with each other through the dust collecting inlet 7. . In this state, the flow path switching member 3a of the flow path switching valve 3 is lowered so that the first common air flow path 17a and the second common air flow path 17b are blocked by the flow path switching member 3a. When the blower fan 20 is operated after the common air path 17a and the dust collection air path 21 are connected to each other, the suction force of the blower fan 20 is reduced through the second common air path 17b. 7), so that the air inside the support part 32 of the dust collecting box 30 removes the air outlet 36 for removing dust, the air inlet 7 for removing dust, and the second common air path 17b, It is sucked to the rear of the blowing fan 20 via the suction hole 4, and is injected into the filter member 13 through the dust collecting air passage 21, the first common air passage 17a, the filter member 13 Dust and dust collected on the dust collecting chamber (C), such as dust and dust collector (14) attached to the filter member 13 while passing through) for cleaning suction port 11 and dust collection Through the air inlet 33 is introduced into the granular portion 31 of the dust box (30).

The air containing the dust sucked into the granular portion 31 of the dust collecting box 30 is supported by the suction portion of the blowing fan 20 in the air flow space 31a of the granular portion 31. The dust is collected while passing through the dust collecting filter member 35 in the process of flowing into the internal air flow space (32a) of the dust. The dust filtered air outlet 36 for collecting dust in the interior of the support (32), The dust collecting suction port 7, the second common air flow path 17b, the suction hole 4, and the blowing fan 20 flow back to the rear of the blowing fan 20, and the above-described dust collecting process is repeated. Done.

As described above, according to the present invention, since the filter is always kept clean after cleaning, there is no decrease in suction power, no smell due to decay of contaminants, and the dust storage space can be designed to be small, thereby reducing the size of the cleaner body. This is hygienic because the user does not have to shake off the fine filter directly.
