Definitions

  • the present invention relates to a vacuum cleaner, and more particularly, to a cyclone dust collector for vacuum cleaner, which can suck and collect various kinds of pollutant such as dust utilizing a cyclonic principle.
  • the generated suction force is transmitted to the suction nozzle 2 through the suction hose 3, the handle pipe 4 and through the extension pipe 5, thereby the dust-laden air is sucked through the suction nozzle 2 and introduced into the dirt collecting apparatus 1c of the canister body 1 through the extension pipe 5, the handle pipe 4 and through the suction hose 3.
  • the collected dust and various foreign matters remain inside the dirt collecting apparatus 1c while air passes through the dirt collecting apparatus 1c and is discharged outwardly from the canister body 1.
  • the conventional vacuum cleaner which uses the single-use dirt collecting apparatus 1c for collecting the dust and foreign matters should be separated from the canister body 1 when the collected dust is discarded, thereby causing the separation and the installation of the dirt collecting apparatus to be troublesome.
  • the dust and debris collected inside the dirt collecting apparatus 1c can be decayed, thereby causing a generation of an offensive smell. Furthermore, to replace the dirt collecting apparatus 1c, the canister body 1 must be disassembled, thereby being inconvenient in its maintenance.
  • a collector body 11 having an inlet pipe 12 formed at an end side thereof for sucking air and pollutant (dust, debris or the likes) and an outlet pipe 13 formed at the other end side thereof for discharging the introduced dust-laden air into the collector body 11.
  • pollutant dust, debris or the likes
  • the inlet pipe 12 is connected to the extension pipe 5 for introducing the dust sucked through the suction nozzle 2 and the outlet pipe 13 is connected to the handle pipe 4 for receiving the suction force generated by the rotation of the fan 1a.
  • a dust outlet 14 is provided in the inner circumference of the collector body 11 on which the outlet pipe 13 is arranged. The dust outlet 14 is connected to a dust box 15, thereby discharging the introduced dust into the dust box 15.
  • the dust contained in the air is rotated and advanced along the inner wall surface of the collector body 11 and discharged into the dust box 15 through the dust outlet 14 and the air is discharged outwardly through the outlet pipe 13.
  • the dust can be rotated and discharged along the collector body 11 through the dust outlet 14.
  • a cyclonic swirling part 20 comprises a plurality of cycloid guiding axial vanes 21 fixed adjacently to the inlet pipe 12 within the collector body 11 to provide the centrifugal force to the dust-laden air introduced into the collector body. That is, the plurality of cycloid guiding axial vanes 21 such as wings of electric fan extend radially and outwardly from a center axis 23 at prescribed intervals respectively, thereby causing the air, which passes through the cyclonic swirling part 20, obtaining the centrifugal force.
  • the cyclonic swirling part 20 can generate the centrifugal force by guiding the flow of air depending on the shape of the cycloid guiding axial vanes 21 during passing through spaces formed between the vanes 21, thereby the collector body provides a poor centrifugal force.
  • the centrifugal force generated during the introduction of the air is relatively weak, thereby the dust is not smoothly separated from the air to drop off in its dust collecting force.
  • the inlet pipe 12 is formed on the center of the end side of the collector body 11 and the air introduced into the collector body 11 through the inlet pipe 12 spreads the inner circumference of the cyclone during the passage of the air through the spaces between the cycloid guiding axial vanes 21 constituting the cyclonic swirling part 20 as well as the flow of air is divided into large numbers by the spaces between the cycloid guiding axial vanes 21.
  • axial blades of the cycloid guiding axial vane 21 are arranged in parallel with the flow of air to divide the flow of air into large numbers, so that the passed air is advanced and rotated along the curved surface of each cycloid guiding axial vane 21.
  • the rotary area of the dust-laden air is determined by a length of the axial vane 21.
  • the conventional axial vane 21 which has the relatively short length provides a small rotary area, thereby resulting in a small rotary power of the particles of dust.
  • the dust-laden air introduced through the inlet pipe 12 passes the cyclonic swirling part 20 from the inner circumference through the central portion of the collector body 11 during the spread procedure, and at this time, the rotary power is reduced in the central portion which has a small diameter.
  • Figure 6 is a perspective view, partly in section, of a cyclonic swirling part according to the present invention.
  • Figure 7 is a perspective view, partly in section, of a first preferred embodiment of a forward cyclone dust collector embodying the cyclonic swirling part of Figure 6.
  • Figure 8 is a sectional view taken along a line of II-II of Figure 7.
  • the cyclone dust collector 100 according to the first embodiment of the present invention includes a cyclonic swirling part 200 consisting of a screw type vane 210, which is disposed inside the collector body 110 and adopted as means for providing a rotary power to dust-laden air.
  • the screw type vane 210 forms a single air flow passage resulting in a small size of the cyclonic swirling part 200, but sufficiently provides a rotary area. It is entirely different from the conventional method of sucking the dust-laden air into the collector body 11 using the conventional cyclonic swirling part 20 having a plurality of axial vanes 21 dividing the air flow passage into large numbers.
  • the cyclonic swirling part 200 of the cyclone dust collector 100 includes an outer body 220 mounted on the inner wall surface of a collector body 110, a central shaft 230 formed integrally with the central portion of the outer case body 220, and the screw type vane 210 formed spirally along the inner circumference of the outer body from the outer surface of the center axis 230.
  • the cyclonic swirling part 200 has the single air flow passage by the above structure. The dust-laden air introduced into the collector body 110 rotates and advances along the air flow passage.
  • cyclonic swirling part 200 may be constructed without the center axis 230 disposed on the central portion of the screw type vane 210.
  • the screw type vane 210 may be formed along the inner wall surface of the collector body 110 or along the inner wall surface of the outer body 220 constituting the cyclonic swirling part 200, and it can be formed on any other locations. It will be recognized that there are other equivalent ways of locating the cyclone dust collector 100 besides the way of locating between the extension pipe 5 and the handle pipe 4, but this embodiment refers to the above structure.
  • the fan 1a When a user manipulates the controller 4a of the handle pipe 4 to operate the fan motor 1b, the fan 1a received the driving force from the fan motor 1b is rotated, thereby causing generating a suction force. The generated suction force is transmitted to the suction nozzle 2 through the suction hose 3, the handle pipe 4, cyclone dust collector 100 and through the extension pipe 5.
  • the dust-laden air sucked through the suction nozzle 2 is introduced into the collector body 110 through an inlet pipe 120.
  • the flow of dust-laden air is guided by the screw type vane 210 during passing through the cyclonic swirling part 200, thereby generating a rotary power. That is, the screw type vane 210 extending spirally between the center axis 230 and the outer body 220 of the cyclonic swirling part 200 provides the flow of air with the rotary power.
  • the air passed through the cyclonic swirling part 200 is discharged outwardly through the outlet pipe 130 arranged on the other end of the collector body 110, rotating along the inner circumference of the collector body 110. At this time, the dust contained in the air is influenced by a centrifugal force, because of its gravity.
  • the dust with the specific gravity is separated from the air and moved toward the outlet pipe 130 portion, rotating along the inner wall surface of the collector body 110.
  • the dust separated from the air is discharged into a dust box 150 through a dust outlet 140 during rotating along the inner wall surface of the collector body 110, while the air is discharged toward the handle pipe 4 through the outlet pipe 130.
  • the cyclone dust collector is constructed for improving the rotary power of the air introduced into the cyclone dust collector.
  • the air outflow portion 121 of the inlet pipe 120 is directed to a inflow portion 211 of the screw type vane 210 constituting the cyclonic swirling part 200.
  • the second embodiment of the dust collector adopting the screw type vane 210 is illustrated.
  • the inlet pipe 120 is arranged eccentrically on the collector body 110, so that the inlet pipe 120 is disposed on the same line as the inflow portion 211 of the screw type vane 210.
  • the dust-laden air which is introduced into the collector body 110 through the inlet pipe 120 is directly delivered to the inflow portion 211 of the screw type vane 210, and a distance, that the rotary power is applied to the dust-laden air by the screw type vane 210, is maximized.
  • the rotary power of the dust-laden air rotating along the inner wall surface of the collector body 110 through the cyclonic swirling part 200 is generated more strongly, thereby improving the separating efficiency of the dust from the air.
  • FIG. 12 and 13 a third embodiment for improving the rotary power of the air is illustrated.
  • the inlet pipe 120 is arranged centrally on the collector body 110 not eccentrically, but it has the same or more improved effect of rotary power.
  • a distance between the air outflow portion of the inlet pipe 120 and the air inflow portion of the cyclonic swirling part 200 is shortened to a minimum, thereby resulting in minimizing the diffusion of the dust-laden air passing through the space.
  • the inlet pipe 120 is arranged eccentrically on the end side of the collector body 110 in state that the distance between the air outflow portion of the inlet pipe 120 and the inflow portion of the cyclonic swirling part 200 is minimized.
  • the air outflow portion of the inlet pipe 120 is located as shown in Figure 15. It will be appreciated that other equivalent constructions of cyclone dust collector having the cyclonic swirling part 200 can be used, but it is preferable that the outflow portion of the inlet pipe 120 is structured as shown in Figure 15.
  • the improved air flow passage structure inside the collector body of the cyclone dust collector has the following effects.
  • the flow of air is not divided into large numbers but is formed in a single, thereby leading to a concentration of the suction force to largely increase the rotary power of the introduced air. Therefore, the dust can be smoothly separated from the air, thereby sharply reducing the resistance of the air to eliminate the cause of a noise.
  • the bulky foreign matters which are introduced into the collector body can be smoothly discharged into the dust box of the collector body, thereby preventing a stop of the air flow passage to solve problems such as the suction impossibility.
  • the cyclonic swirling part with a smaller size has a sufficient area for the rotation, thereby improving the rotary power.
