The present invention relates to a cyclone dust collector that can collect various foreign matters using the cyclone principle, and more particularly, to a cyclone dust collector provided with a cleaning liquid supply device to supply a cleaning liquid into the cyclone body. It is about.                         

In general, a cyclone dust collector is a device that discharges air out of the pollutants rotating with air by using centrifugal force and separates only the pollutants (dust, lint, scrap, etc.) from the air.

Various types of cyclone dust collectors using the same principle have been proposed, and among them, a cyclone dust collector having a cleaning liquid supply device for supplying the cleaning liquid to the inside of the cyclone body to improve dust collection performance An example will be described with reference to the accompanying drawings.

1 is a cross-sectional view schematically showing a cyclone dust collector according to the prior art, Figure 2 is a state diagram of the cyclone dust collector according to the prior art.

As shown in FIG. 1, the cyclone dust collector according to the related art is connected to the cyclone body 100 having a vertical cylindrical shape in a vertical direction, and tangentially connected to an upper end of the circumferential surface 100b of the cyclone body 100. Suction channel 110, foreign matter discharge pipe 120 connected to the dust collector 180 from the lower end of the peripheral surface (100b), and discharge flow channel formed through the center of the upper surface (100a) of the cyclone body (100) 130).

At this time, the suction channel 110 is connected to suck the air and various foreign matter from the outside, the discharge side of the discharge channel 130 is installed, for example, suction force generating means (not shown) consisting of a fan and a motor, etc. In connection with the space, the suction force generated by the rotation of the fan is transferred into the cyclone body 100.

Therefore, when the suction force is transmitted through the discharge flow path tube 130, the suction force is transferred to the suction flow path tube 110 through the cyclone body 100, so that various foreign substances and air from the outside flow into the suction flow path. It is sucked into the cyclone body 100 through the tube 110.

At this time, air and various foreign substances introduced into the cyclone body 100 through the suction flow path 110 are separated along each other while turning along the inner wall surface of the cyclone body 100.

This is because the suction flow path 110 is connected in a tangential direction to the circumferential surface (100b) of the cyclone body 100, the air and various foreign substances introduced into the cyclone body (100) is The air that is pivoted along the inner wall surface of the cyclone body 100, in which the mass is almost neglected, is separated from various foreign matters as it is hardly subjected to centrifugal force.

In addition, as described above, various foreign matters separated from the air move downward by riding on the inner wall surface of the cyclone body 100 by its own weight, and the foreign substance discharge pipe connected to the lower end of the circumferential surface 100b of the cyclone body 100. It is discharged to the dust collector 180 through 120.

Air separated from the foreign matter is collected is discharged to the space in which the suction force generating means is installed through the discharge flow path tube 130 while forming a rising air flow rising from the lower side in the cyclone body (100).

On the other hand, in the process of introducing foreign matter into the cyclone body 100, the fine dust itself is extremely insignificant because the separation by the centrifugal force is not made smoothly does not flow to the bottom of the cyclone body (100) While continuously turning on the upper side of the cyclone body 100, the generation of static electricity is intensified as the friction between the fine dust and the cyclone body 100 is continuously made, and due to the static electricity, the cyclone body ( 100) There was a problem in that the swirl flow of the fine dust turning along the inner wall is lowered, resulting in a lower dust collection efficiency.

In order to solve this problem, for example, a reservoir 190 for accommodating a cleaning liquid, such as water, and a water supply pipe 191 connected to the suction flow pipe 110 of the cyclone body 100 from the reservoir 190, It is connected to the water supply pipe 191 is provided with a separate cleaning solution supply device consisting of a pumping means (195) for supplying the cleaning solution in the reservoir 190 to the suction flow path pipe 110, the cyclone body 100 inside By supplying the washing liquid to the micro-dust inside the cyclone body 100 to increase the weight by giving a greater centrifugal force to the fine dust, it was possible to easily collect.

However, according to the conventional washing liquid supply structure, there were the following problems.

That is, as shown in Figure 2, the washing liquid of the reservoir 190 is injected into the suction flow path 110 of the cyclone body 100 through the water supply pipe 191 is supplied to the cyclone body 100 inside the In this case, due to the strong suction force by the suction force generating means for generating the turning force inside the suction flow channel 110, a portion of the cleaning liquid supplied from the water supply pipe 191 is the upper surface (100a) of the cyclone body 100 Agglomerated inside to form a droplet (192, 水滴), the droplet 192 is moved along the upper surface (100a) to the discharge flow path tube 130 side, the droplet (192) moved to the discharge flow path tube 130 side. ) Is discharged to the space in which the suction force generating means is installed through the discharge flow path tube 130 by the suction air generated by the cyclone body 100 and the suction force generated by the suction force generating means.

As a result, the cleaning liquid is introduced into various components such as a motor constituting the suction force generating means, thereby causing damage to the suction force generating means, thereby preventing the introduction of the cleaning liquid into the space where the suction force generating means is located. In order to require a separate sealing means, there was a problem of decrease in productivity due to the increase in the number of parts and the complexity of the structure.

In addition, as the cyclone body 100 becomes smaller, the moving distance of the droplets becomes shorter, so that the water droplets agglomerated on the inner upper surface 100a of the cyclone body 100 are installed along the discharge flow path tube 130. As the discharge phenomenon is further intensified, it has contributed to the miniaturization of the cyclone dust collector.

The present invention has been made to solve the above-mentioned conventional problems, the present invention is a cyclone dust collector to minimize the discharge of the cleaning liquid supplied into the cyclone body to the suction force generating means side through the discharge flow channel For the purpose of providing

In order to achieve the above object, according to the present invention, the cyclone body of the substantially cylindrical shape having a length in the vertical direction, and is installed to cover the outer surface of the lower surface and the circumferential surface of the cyclone body to the inside of the cyclone body A dust collecting tube for collecting foreign substances discharged from the body, a suction flow channel through which external air containing foreign substances flows into the inner lower portion of the cyclone body, and penetrated through the upper surface of the cyclone body to discharge air toward the suction force generating means; A foreign matter discharge hole formed in the circumferential surface of the cyclone body to discharge the discharge flow path tube, the foreign matter centrifuged in the cyclone body and the cleaning liquid to the dust collecting side, and the cleaning liquid into the cyclone body through the suction flow pipe.
