Cyclone collector for vacuum cleaner {cyclone collector for vacuum cleaner}
[8] The present invention relates to a cyclone dust collector, and more particularly to a cyclone dust collector for vacuum cleaner suitable for use in a vacuum cleaner.
[9] In general, a cyclone collector is a device for collecting contaminants (dust, lint, scrap, etc.) contained in the air by using the cyclone principle. Cyclone dust collectors are used in various fields, and are mainly applied to vacuum cleaners for home use.
[10] Hereinafter, referring to the configuration of the cyclone dust collector according to the prior art as follows.
[11] As shown in FIGS. 1 and 2, the cyclone dust collector includes a first dust collector 10 for performing primary dust collection using an inertial force, and a second dust collector 20 for performing secondary dust collection using a centrifugal force. Is made large.
[12] Here, the first dust collector 10, the inertial dust collecting body 11 forming the body of the first dust collector, and the inlet pipe 12 for introducing external polluted air (air containing contaminants) into the inertial dust collecting body. And, it consists of a partition wall 13 for partitioning the auxiliary dust collecting part (13a) inside the inertial dust collecting body.
[13] In addition, the second dust collector 20, the cyclone body 21, the polluted air suction pipe 22 for communicating the cyclone body and the inertial dust collecting body 11 and sucks contaminated air into the cyclone body, and the It consists of an air discharge pipe 23 for discharging the purified air from the cyclone body, and a pollutant discharge port 24 for discharging the pollutant separated from the cyclone body.
[14] In addition, the first dust collector 10 and the second dust collector 20 are located in parallel in the longitudinal direction.
[15] Hereinafter, referring to FIG. 2, the operation of the cyclone dust collector according to the related art will be described.
[16] First, when the air suction unit (not shown) provided in the air discharge pipe 23 side of the second dust collector 20 is operated, air or contaminants flow into the inlet pipe 12 of the first dust collector 10, Among the pollutants, the large particles are collected by the inertial force to the lower end of the inertial dust collecting body 11, wherein the particles having a relatively large mass among the large particles collide directly with the bottom surface of the inertial dust collecting body 11 to be splashed. The particles having a relatively small mass among the large particles rotate in a direction toward the contaminated air suction pipe 22 (right direction in FIG. 2), and then bounce against the inner surface of the inertial dust collecting body 11, particularly, inertia. The collision between particles bounced from the bottom surface of the dust collecting body 11 and particles bounced from the inner surface of the dust collecting body 11 is so intense that irregular movement of the contaminants continues, and the force applied to the particles after a certain time. When it weakens, It is presented toward the dust collecting at the lower end of the inertial dust collector body (11).
[17] At the same time, the fine particles of air or non-dust collected contaminants are introduced into the second dust collector along the tangential direction of the cyclone body 21 constituting the second dust collector 20 through the contaminated air suction pipe 22. Is discharged to the outside through the air discharge pipe 23 and the fine particles are subjected to centrifugal force along the tangential direction. The fine particles subjected to the centrifugal force continue to circle and reach the pollutant outlet 24 to be collected by the secondary dust collector 13a of the first dust collector 10 through the pollutant outlet.
[18] However, the cyclone dust collector according to the prior art made as described above has the following problems.
[19] First, some of contaminants introduced into the inertial dust collecting body 11 of the first dust collector 10 and bounced against the bottom surface of the inertial dust collecting body by inertial force or some of the particles that bounce off the inner surface of the inertial dust collecting body The phenomenon of exiting the contaminated air suction pipe 22 of the second dust collector 20 occurs, which causes a problem that the dust collection efficiency of the first dust collector 10 is lowered.
[20] Second, the contaminants introduced into the inertial dust collecting body 11 of the first dust collector 10 have an irregular motion while hitting the inner wall of the inertial dust collecting body. As the number of frictions with the inner wall increases, static electricity is generated, which causes a problem that the reliability of the device is lowered.
[21] The present invention is to solve the problems of the prior art, and to improve the structure of the cyclone dust collector, to improve the dust collection efficiency of the first dust collector and to reduce the generation of static electricity of the first dust collector.

[22] In order to achieve the above object, the present invention, in the cyclone dust collector comprising a first dust collector for performing the first dust collection using the inertial force, and a second dust collector for performing the secondary dust collection using the centrifugal force, the first It provides a cyclone dust collector, characterized in that the turbulence prevention member is included in the first dust collector so that the flow of contaminant particles flowing into the dust collector is reduced in the first dust collector.
[23] Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.
[24] 3 is a cross-sectional view taken along line II of FIG. 1 showing a cyclone dust collector according to the present invention.
[25] Prior to the description of the drawings, the cyclone dust collector has been mentioned in the prior art, and thus the description thereof will be omitted, and only the same structure as the prior art will be given the same reference numeral as in the prior art.
[26] As shown in FIG. 3, the cyclone dust collector according to the present invention includes a first dust collector 10 performing primary dust collection using an inertial force, and a second dust collector 20 performing secondary dust collection using a centrifugal force. ) And a turbulence preventing member 14 is included in the first dust collector so that the flow of contaminant particles flowing into the first dust collector is reduced in the first dust collector.
[27] At this time, the turbulence prevention member 14, as shown in Figure 3, is provided in at least one or more in the inertial dust collection body 11 forming the body of the first dust collector, collides with the pollutant particles to prevent the flow of pollutants It may be a plate-like member that interferes. Here, the plate-shaped member (hereinafter referred to as "turbulence prevention plate") is preferably provided on the bottom surface of the inertial dust collecting body 11 to have a predetermined height (height to interfere with the flow of pollutants). In order to reduce the flow of contaminants, it is preferable that the surface of the turbulence preventing plate 14 is positioned in a direction opposite to the direction of movement of the contaminants introduced into the inlet pipe 12.
[28] In addition, the cyclone dust collector according to the present invention, as shown in Figure 3, the contaminant particles flowing into the first dust collector 10, the inner bottom of the inertial dust collecting body 11 forming the body of the first dust collector. In order not to directly collide with the surface, the inertial collision plate 15 may be further provided on the inlet tube 12 side in the inertial dust collecting body. Here, the inertial collision plate is for converting the direction of the contaminant particles directly down to the bottom surface of the inertial dust collecting body 11 among the contaminants in another direction, and at a predetermined angle (an angle sufficient to allow the contaminants to flow to the turbulence plate) It is preferable to take the bent form.
[29] Hereinafter, with reference to Figure 3, the operation of the cyclone dust collector according to the present invention will be described.

After the contaminants introduced into the inlet pipe 12 hit the inertial collision plate 15 and are turned in the right direction in FIG. 3, the large particles are shorter in distance depending on the mass size of the contaminant particles. After moving and hitting the first installed turbulence blocking plate 14 in the right direction of FIG. 3, the vortex flow is converted into linear flow, and then collected by the gravity effect to the lower end of the inertial dust collecting body 11, and the particles having a small mass are (長) distance to the last direction in the right direction of Figure 3 After hitting the turbulence blocking plate 14, the vortex flow is converted into a linear flow and then collected by the lower end of the inertial dust collecting body 11 under the influence of gravity.
[31] At the same time, the fine particles of air or non-dust collected contaminants are introduced into the second dust collector along the tangential direction of the cyclone body 21 constituting the second dust collector 20 through the contaminated air suction pipe 22. Is discharged to the outside through the air discharge pipe 23 and the fine particles are subjected to centrifugal force along the tangential direction. The fine particles subjected to the centrifugal force continue to circle and reach the pollutant outlet 24 to be collected by the secondary dust collector 13a of the first dust collector 10 through the pollutant outlet.
[32] As a result, the present invention reduces the irregular flow of the pollutants introduced into the first dust collector 10 to collect the pollutants at the lower end of the inertial dust collector body 11, so that the pollutants to be inertia collected by the first dust collector are It is possible to considerably reduce the phenomenon that the first dust collector is not collected and escape to the second dust collector 20, and significantly reduce frictional static electricity between the contaminant particles and the inner wall of the inertial dust collecting body generated by the irregular flow of the pollutants.
