A canister type vacuum cleaner is generally used in a state where the bottom surface of the cleaner body is opposed to the floor surface (sideways). On the other hand, the electric vacuum cleaner is often stored in a state where the vacuum cleaner main body is set up (vertical direction). In this state, the bottom surface of the cleaner body faces sideways. By placing the vacuum cleaner body vertically, the vacuum cleaner can be stored compactly.

  A canister type vacuum cleaner often has a handle attached to the front portion of the vacuum cleaner body. The handle is for holding the vacuum cleaner body. When carrying the vacuum cleaner body with the handle, the vacuum cleaner body is arranged vertically.

JP 2011-212171 A

  In a vacuum cleaner equipped with a cyclone separator, the cyclone separator is turned upside down when the vacuum cleaner body is arranged vertically. If the main body of the vacuum cleaner is arranged vertically when the electric blower is operating, the dust collected in the dust collection chamber will flow back into the swirl chamber. There was a problem that the airflow in the swirl chamber was disturbed and the separation performance of the cyclone separation device was lowered.

  In addition, when the vacuum cleaner main body is arranged vertically, the dust collected in the dust collection chamber may reach the vicinity of the inlet of the swirl chamber. If the cyclone separator is removed from the main body of the vacuum cleaner in this state, dust will fall out from the cyclone separator. There was a problem that the main body of the vacuum cleaner and the floor were dirty and not hygienic.

  Such a problem may occur not only in a canister type vacuum cleaner but also in other types of vacuum cleaners.

  The present invention has been made to solve the above-described problems. The purpose of the present invention is to collect dust collected in the dust collection chamber in the swirl chamber even when it is disposed upside down. It is providing the cyclone separator which can prevent entering and the vacuum cleaner provided with such a cyclone separator.

  The cyclone separating apparatus according to the present invention is arranged in the first direction when the bottom surface of the storage unit is directed downward while being attached to the storage unit, and is disposed in the second direction when the bottom surface is directed sideways. A separation device that swirls dust-containing air flowing in from an inlet along a side wall to separate dust from the dust-containing air, an opening formed in the side wall, and communicates with the swirl chamber through the opening. A dust collection chamber in which dust separated in the swirl chamber is collected, and the dust collection chamber extends from the opening in both one direction and the other direction along the central axis of the swirl chamber, and surrounds the swirl chamber Is disposed in a first direction, a part of the dust collecting chamber is disposed below the opening, and when disposed in the second direction, a part of the dust collecting chamber is disposed below the opening. Is to be placed.

  An electric vacuum cleaner according to the present invention includes the cyclone separating device and a vacuum cleaner body including the cyclone separating device and a housing unit.

  According to the present invention, in the vacuum cleaner equipped with the cyclone separator and the cyclone separator, even if the garbage is disposed upside down, the dust collected in the dust collection chamber enters the swirl chamber. This can be prevented.

The connection port 21 is arranged near the rear end and one side on the upper surface of the housing unit 12.

The dust collection unit 13 is for separating garbage from dust-containing air and temporarily storing the separated garbage. The dust collection unit 13 turns dust-containing air inside to separate dust from air by centrifugal force. That is, the dust collection unit 13 has a cyclone separation function.
The specific configuration and function of the dust collection unit 13 will be described later.

  The exhaust air passage forming unit 17 forms the exhaust air passage 22. The exhaust air passage 22 is a space for guiding the air discharged from the dust collection unit 13 to the exhaust port (not shown) in the cleaner body 6. One end of the exhaust air passage forming portion 17 opens at the upper surface of the housing unit 12. The one end of the exhaust air passage forming unit 17 forms a connection port 23 with the dust collection unit 13. The connection port 23 is arranged at the center near the rear end on the upper surface of the housing unit 12. The other end of the exhaust air passage forming unit 17 forms the exhaust port.

  The electric blower 10 generates an airflow in an air passage formed in the vacuum cleaner 1 (including an air passage in the dust collecting unit 13). The electric blower 10 is disposed in the exhaust air passage 22 near the rear end of the housing unit 12.

  When the electric blower 10 starts the suction operation, an air flow (suction air) is generated in each air passage formed in the electric vacuum cleaner 1. The dust-containing air sucked from the suction port body 2 is taken into the cleaner body 6 from the hose connection port 9. The dust-containing air that has flowed into the cleaner body 6 is sent to the dust collection unit 13 from the connection port 21 via the intake air passage 20. The airflow generated inside the dust collection unit 13 will be described later. Air (clear air) discharged from the dust collection unit 13 flows into the exhaust air passage 22 and passes through the electric blower 10. The air that has passed through the electric blower 10 is then discharged from the exhaust port to the outside of the cleaner body 6.

The front wheel 18 and the rear wheel 19 are provided for smoothly moving the cleaner body 6.
The front wheel 18 is provided so as to be rotatable with respect to the housing unit 12. The front wheel 18 is disposed near the front end of the housing unit 12. A part of the front wheel 18 protrudes from the bottom surface 12 b of the housing unit 12.

  Specifically, the front wheel 18 is attached to the container 14 via the shaft 24, the attachment member 25, and the shaft 26. The shaft 24 is fixed to the container 14. The shaft 24 is disposed perpendicular to the bottom surface 12b. The front wheel 18 is rotatably provided on the attachment member 25 via a shaft 26. The attachment member 25 is rotatably provided on the container 14 via the shaft 24. The shaft 26 is always disposed horizontally with respect to the bottom surface 12b.

  The rear wheel 19 is provided to be rotatable with respect to the housing unit 12. The rear wheels 19 are disposed on both sides of the housing body 14 near the rear end of the housing unit 12. As with the front wheel 18, a part of the rear wheel 19 protrudes from the bottom surface 12 b of the storage unit 12.

  2 to 4 show a state in which the cleaner body 6 is disposed sideways. 9 is a cross-sectional view taken along the line CC of the cleaner body shown in FIG. FIG. 10 is a DD cross-sectional view of the cleaner body shown in FIG.

  “Landscape” is the direction in which the front wheels 18 and the rear wheels 19 are in contact with the floor surface (for example, a running state). When the cleaner body 6 is disposed sideways, the bottom surface 12b of the housing unit 12 faces downward and is disposed substantially parallel to the floor surface. That is, the bottom surface 12b faces the floor surface. When the cleaner body 6 is disposed sideways, the hose connection port 9 opens sideways (front).

  Usually, a user cleans by arranging the cleaner body 6 sideways. The user cleans while holding the handle 7 and moving the suction port body 2 back and forth. When moving the place to be cleaned, the user pulls the cleaner body 6 through the suction hose 5. The cleaner body 6 moves smoothly in the direction pulled by the user as the front wheels 18 and the rear wheels 19 roll on the floor surface.

  On the other hand, when cleaning is completed and the vacuum cleaner 1 is stored in a storeroom, the user arranges the vacuum cleaner body 6 in a vertical orientation. FIG. 11 is a side view showing the vacuum cleaner main body arranged vertically. 12 is a cross-sectional view of the cleaner body shown in FIG.

  “Vertical orientation” is an orientation in which at least one of the front wheel 18 and the rear wheel 19 is separated from the floor surface and the bottom surface 12b of the storage unit 12 faces sideways. In the present embodiment, the case where the bottom surface 12b is arranged slightly obliquely upward is shown. When the vacuum cleaner main body 6 is arranged vertically, the cleaner body 6 is rotated about 90 degrees from the horizontal state about the horizontal axis. When the cleaner body 6 is arranged vertically, the back surface 12c of the housing unit 12 faces the floor surface. The back surface 12c is a surface that faces backward when the cleaner body 6 is disposed sideways. When the cleaner body 6 is arranged vertically, the hose connection port 9 opens upward.

  The details of the dust collection unit 13 when the cleaner body 6 is disposed in the horizontal and vertical directions will be described later.

The dust collection unit 13 will be described in detail with reference to FIGS.

  The dust collection unit 13 has a substantially cylindrical shape as a whole. The dust collection unit 13 includes a discharge part case 27, a bypass part case 28, an inflow part case 29, and a dust collection part case 30.

  The discharge part case 27, the bypass part case 28, the inflow part case 29, and the dust collecting part case 30 are made of molded products, for example. The discharge part case 27, the bypass part case 28, the inflow part case 29, and the dust collecting part case 30 can be disassembled into the state shown in FIG. 16 or assembled into the state shown in FIG. Moreover, only the dust collection part case 30 can be removed from the state shown in FIG.

  17 is an EE cross-sectional view of the dust collection unit shown in FIG. 18 is an FF cross-sectional view of the dust collection unit shown in FIG. FIG. 19 is a cross-sectional view of the dust collection unit shown in FIG. 20 is a cross-sectional view of the dust collection unit shown in FIG. FIG. 21 is a JJ cross-sectional view of the dust collection unit shown in FIG. FIG. 22 is a plan view showing a bypass case of the dust collection unit of the electric vacuum cleaner according to Embodiment 1 of the present invention. FIG. 23 is a plan view showing an inflow portion case of the dust collection unit.

  By appropriately arranging one or more of the cases shown in 27 to 30, the dust collection unit 13 is provided with the inflow air passage 31, the bypass inflow air passage 32, the swirl chamber 33, the zero-order dust collection chamber 34, and the primary collection chamber. A dust chamber 35 and an outflow air passage 36 are formed.

  The inflow part case 29 includes a cylindrical part 37, a conical part 38, an inflow pipe 39, a bypass air path forming part 40, and a connection part 41.

  The cylindrical portion 37 has a cylindrical shape. The cylindrical portion 37 is arranged so that the central axis is directed in the vertical direction. The conical portion 38 has a hollow conical shape with a tip portion cut off. The central axis of the conical part 38 is arranged in the vertical direction so as to coincide with the central axis of the cylindrical part 37. The conical portion 38 has an upper end connected to the lower end of the cylindrical portion 37. The conical portion 38 is provided so as to extend downward from the lower end portion of the cylindrical portion 37 so that the diameter decreases as it goes downward. The lower end portion of the conical portion 38 opens downward (center axis direction). This opening formed at the lower end of the conical portion 38 is the primary opening 42.

  A continuous space composed of the internal space of the cylindrical portion 37 and the internal space of the conical portion 38 constitutes the swirl chamber 33. The swirl chamber 33 is a space for swirling dust-containing air. The central axis of the swirl chamber 33 coincides with the central axis of the cylindrical portion 37 and the central axis of the conical portion 38.

  The inflow pipe 39 is for guiding the dust-containing air that has passed through the intake air passage 20 to the inside of the cylindrical portion 37 (the swirl chamber 33). The internal space of the inflow pipe 39 constitutes the inflow air path 31. The inflow air passage 31 is one of air passages for allowing dust-containing air to flow into the swirl chamber 33 from the intake air passage 20.

  The inflow pipe 39 has, for example, a square cylindrical shape. The inflow pipe 39 is connected to the cylindrical portion 37. One end of the inflow pipe 39 opens outward, and the other end opens inside the cylindrical portion 37. The one end of the inflow pipe 39 forms a unit inlet 43. The unit inlet 43 is an opening for taking dust-containing air into the dust collection unit 13. The other end of the inflow pipe 39 forms a main inlet 44. The main inflow port 44 is an opening for taking in the dust-containing air that has passed through the inflow air passage 31 into the cylindrical portion 37 (the swirl chamber 33).

  The inflow pipe 39 is connected to the upper part of the cylindrical portion 37. For this reason, the main inflow port 44 is formed in the upper part of the cylindrical portion 37. That is, the main inlet 44 is formed at the uppermost part of the side wall that forms the swirl chamber 33. The inflow pipe 39 is made of a straight member. The inflow pipe 39 has an axis perpendicular to the central axis of the cylindrical portion 37 and is disposed in the tangential direction of the cylindrical portion 37.

  The inflow pipe 39 has a bypass inlet 45 formed on the upper surface thereof. That is, the bypass inlet 45 is formed in the upper wall that forms the inflow air passage 31. The bypass inlet 45 is an opening for taking a part of the dust-containing air in the inflow air passage 31 into the bypass inflow air passage 32. In the dust collection unit 13, a bypass inflow air passage 32 is provided in addition to the inflow air passage 31 as an air passage for allowing dust-containing air to flow from the intake air passage 20 into the swirl chamber 33.

  The bypass inflow air passage 32 is formed by a part of each of the discharge portion case 27, the bypass portion case 28, and the inflow portion case 29. Part of the dust-containing air flowing through the inflow air passage 31 is taken into the bypass inflow air passage 32 via the bypass inflow port 45. After passing through the bypass inflow air passage 32, the dust-containing air is taken into the cylindrical portion 37 (the swirl chamber 33) from the auxiliary inlet 46.

  The bypass air path forming unit 40 is provided on the upper portion of the cylindrical portion 37 so as to surround the periphery of the cylindrical portion 37. The bypass air passage forming portion 40 is placed on the upper surface thereof so that the bypass portion case 28 is in close contact therewith. On the upper surface of the bypass air passage forming portion 40, a rising portion 47 for determining the mounting direction of the bypass portion case 28 is provided at the edge thereof.

  The bypass air passage forming portion 40 is provided with three grooves 48 that open upward. The groove 48 is formed outside the cylindrical portion 37 so as to be along the outer peripheral surface of the cylindrical portion 37. One end of the groove 48 opens into the cylindrical portion 37.

  The bypass air passage formation portion 40 forms a part (second half portion) of the bypass inflow air passage 32 by closing the upper portion of the groove 48 by the bypass portion case 28. Further, the opening at one end of the groove 48 is closed by the bypass portion case 28, thereby forming a secondary inlet 46. In the present embodiment, three auxiliary inlets 46 are provided on the side wall forming the swirl chamber 33.

  Similar to the main inlet 44, the auxiliary inlet 46 is formed at the upper part of the cylindrical portion 37. That is, the auxiliary inlet 46 is formed at the uppermost part of the side wall that forms the swirl chamber 33. The secondary inlet 46 is disposed at substantially the same height as the main inlet 44. The opening area of the secondary inlet 46 is smaller than the opening area of the main inlet 44. Dust-containing air from the bypass inflow air passage 32 flows into the cylindrical portion 37 from the tangential direction.

  The connection part 41 is provided so as to protrude outward from the cylindrical part 37. The connection part 41 exhibits a ring shape as a whole. The connecting portion 41 is disposed at a substantially intermediate height of the cylindrical portion 37.

The dust collection unit case 30 includes a bottom 49, an outer wall 50, and a partition wall 51.
The bottom 49 has a circular shape as a whole. The outer wall portion 50 has a cylindrical shape with a larger diameter than the cylindrical portion 37. The outer wall portion 50 is provided so as to stand upright from the edge portion of the bottom portion 49. That is, the outer wall portion 50 and the bottom portion 49 form a cylindrical member that is closed on one side (lower side). The partition wall portion 51 has a cylindrical shape with a smaller diameter than the cylindrical portion 37. The partition wall portion 51 is disposed inside the outer wall portion 50. The partition wall 51 is provided so as to stand upright from the upper surface of the bottom 49. For this reason, in the dust collecting unit case 30, two spaces separated by the partition wall 51 are formed inside.

  The upper end part of the partition part 51 contacts the outer peripheral surface of the cone part 38 from below. Of the space formed inside the partition wall portion 51, a portion excluding the conical portion 38 forms the primary dust collection chamber 35. The primary dust collection chamber 35 communicates with the swirl chamber 33 through the primary opening 42. Part of the dust separated from the dust-containing air in the swirl chamber 33 falls into the primary dust collection chamber 35 through the primary opening 42 and is collected. The primary dust collection chamber 35 covers the lower part of the cone part 38, and is arrange | positioned so that the circumference | surroundings may be surrounded.

  The upper end part of the outer wall part 50 contacts the edge part of the connection part 41 from the downward direction. A continuous space having a cylindrical shape is formed between the outer wall portion 50 and the partition wall portion 51 and between the outer wall portion 50 and each part of the cylindrical portion 37 and the conical portion 38. This continuous space is a zero-order dust collection chamber 34. The zero-order dust collecting chamber 34 is closed by the connecting portion 41 on the upper side and the bottom portion 49 on the lower side. The zero-order dust collection chamber 34 is disposed so as to surround the lower portion of the cylindrical portion 37 and the periphery of the conical portion 38 (that is, the periphery of the swirl chamber 33). The zero-order dust collection chamber 34 is disposed so as to surround the primary dust collection chamber 35.

  The zero-order opening 52 is provided on the side wall that forms the swirl chamber 33. The swirl chamber 33 communicates with the zero-order dust collection chamber 34 through the zero-order opening 52. The zero-order opening 52 is formed on the downstream side of the main inlet 44 and the auxiliary inlet 46. Further, the zero-order opening 52 is formed on the upstream side of the primary opening 42. For example, the zero-order opening 52 is provided from the lower end portion of the cylindrical portion 37 to the upper end portion of the conical portion 38. The bottom 49 of the dust collecting unit case 30 is disposed below the zero-order opening 52. For this reason, the zero-order dust collection chamber 34 is disposed so as to extend from the zero-order opening 52 in one direction (downward in FIG. 17) along the central axis of the swirl chamber 33. Further, the connecting portion 41 is disposed above the zeroth order opening 52. For this reason, the zero-order dust collection chamber 34 is disposed so as to extend from the zero-order opening 52 in the other direction (upward in FIG. 17) along the central axis of the swirl chamber 33.

The bypass part case 28 includes a bottom part 53, a side wall part 54, and a discharge part 55.
The bottom portion 53 has a plate shape whose outer shape follows the inner surface of the rising portion 47. When the bypass portion case 28 is appropriately disposed with respect to the inflow portion case 29, the bottom portion 53 closes the upper portion of the cylindrical portion 37 and the upper portion of the groove 48. That is, the upper wall of the swirl chamber 33 is formed by the bottom 53. The upper wall of the rear half of the bypass inflow air passage 32 and the upper edge of the auxiliary inlet 46 are formed by the bottom 53.

  The side wall portion 54 is provided so as to stand upright from the bottom portion 53. The side wall portion 54 is continuously formed so as to surround the C-shaped space formed on the bottom portion 53. The bypass part case 28 is covered with a discharge part case 27 from above. The upper part of the C-shaped space is closed by the discharge part case 27, thereby forming a part (front half part) of the bypass inflow air passage 32.

A first bypass opening 56 and a second bypass opening 57 are formed in the bottom portion 53.
The first bypass opening 56 is an opening for taking the dust-containing air in the inflow air passage 31 into the first half of the bypass inflow air passage 32. The first bypass opening 56 is disposed, for example, immediately above the bypass inlet 45.

  The second bypass opening 57 is an opening for taking dust-containing air in the first half of the bypass inflow air passage 32 into the second half of the bypass inflow air passage 32. For example, the second bypass opening 57 is disposed immediately above the end of the groove 48.

  The discharge part 55 is for discharging the air in the swirl chamber 33 out of the swirl chamber 33. The internal space of the discharge part 55 constitutes the first half part of the outflow air passage 36. The outflow air passage 36 is an air passage through which the air in the swirl chamber 33 flows out of the dust collection unit 13.

  The discharge part 55 is provided in the central part of the bottom part 53. The discharge part 55 opens on the upper surface side of the bottom part 53 and projects downward from the bottom part 53. When the bypass portion case 28 is appropriately attached to the inflow portion case 29, the discharge portion 55 is disposed so as to protrude from the upper wall of the swirl chamber 33 into the swirl chamber 33.

  The discharge portion 55 has a cylindrical shape at a portion above a predetermined intermediate position. A portion below the intermediate position of the discharge portion 55 has a hollow conical shape whose diameter decreases as it goes downward. The discharge portion 55 is arranged in the vertical direction so that the central axis coincides with the central axis of the cylindrical portion 37. The internal space of the discharge unit 55, the swirl chamber 33, the zero-order dust collection chamber 34, and the primary dust collection chamber 35 are arranged substantially concentrically in the dust collection unit 13. That is, the central axes of the internal space of the discharge unit 55, the swirl chamber 33, the zero-order dust collection chamber 34, and the primary dust collection chamber 35 are arranged on the same straight line. The lower end of the discharge part 55 is arrange | positioned at the same height as the upper part of the 0th-order opening 52, for example.

  A large number of fine holes are provided in the discharge portion 55. This fine hole constitutes the discharge port 58. The discharge port 58 is an opening for discharging the air in the swirl chamber 33 to the outside of the swirl chamber 33. The discharge port 58 is disposed at a position above the zero-order opening 52. The discharge port 58 is also arranged at the same height as the main inlet 44 and the sub inlet 46. However, the discharge port 58 is not formed in a portion of the discharge portion 55 that directly faces the main inlet 44. A discharge port 58 is formed in a portion of the discharge portion 55 that directly faces the sub-inlet 46.

  The discharge part case 27 is composed of a case body arranged at the uppermost part of the dust collection unit 13. The discharge part case 27 includes a lid part 59 and a discharge part 60.

  When the discharge part case 27 is appropriately disposed with respect to the bypass part case 28, the lid part 59 closes the C-shaped space on the bottom part 53 from above. That is, the upper wall of the front half portion of the bypass inflow air passage 32 is formed by the lid portion 59.

  The discharge part 60 is for switching the traveling direction of the air that has passed through the inside of the discharge part 55 and discharging it outside the dust collection unit 13. The internal space of the discharge part 60 forms the second half part of the outflow air passage 36. The discharge pipe 61 includes a discharge unit 55 and a discharge unit 60.

  The discharge unit 60 has a cylindrical shape bent into an L shape. The discharge part 60 opens with one end facing downward and the other end facing sideways. One end of the discharge unit 60 is connected to the upper end of the discharge unit 55. Further, on the other end side of the discharge part 60, the central axis is arranged orthogonal to the central axis of the swirl chamber 33 and parallel to the central axis of the inflow pipe 39. The other end of the discharge part 60 forms a unit outlet 62. The unit outlet 62 is an opening through which air flows out from the dust collection unit 13. The unit outlet 62 opens in the same direction as the unit inlet 43. The unit outlet 62 is disposed at a position higher than the unit inlet 43.

Next, the function of the dust collection unit 13 having the above configuration will be specifically described.
Cleaning is performed in a state in which the dust collection unit 13 is appropriately attached to the storage unit 12. When the dust collection unit 13 is appropriately attached to the storage unit 12, the dust collection unit 13 is disposed in the storage unit 15a. At this time, the unit inlet 43 is connected to the connection port 21. The unit outlet 62 is connected to the connection port 23.

  When the user performs cleaning, the dust collection unit 13 is disposed sideways. When the dust collection unit 13 is disposed sideways, the swirl chamber 33 is disposed obliquely with the central axis aligned with the inclination of the upper surface of the storage unit 12. For example, the central axis of the swirl chamber 33 has a certain value in which the angle with the horizontal plane is not less than 0 degrees and not more than 45 degrees (θ1 shown in FIG. 9).

  When the dust collection unit 13 is disposed sideways, the zero-order opening 52 is disposed on the side of the central axis of the swirl chamber 33. As described above, the zero-order dust collection chamber 34 extends from the portion where the zero-order opening 52 is formed in one direction (bottom 49 side) along the central axis of the swirl chamber 33. For this reason, when the dust collection unit 13 is disposed horizontally, a part of the zero-order dust collection chamber 34 is disposed below the zero-order opening 52.

  When the suction operation of the electric blower 10 is started in a state where the dust collection unit 13 is disposed sideways, the dust-containing air passes through the intake air passage 20 and reaches the connection port 21. The dusty air that has reached the connection port 21 passes through the connection port 21 and the unit inlet 43 and flows into the inflow air passage 31. Part of the dust-containing air that has flowed into the inflow air passage 31 goes straight along the central axis of the inflow pipe 39. The dust-containing air passes through the main inlet 44 and flows into the swirl chamber 33. This route is indicated by a solid arrow as a route a in the figure.

  On the other hand, the other part of the dust-containing air that has flowed into the inflow air path 31 enters the path b from the middle of the path a. Specifically, a part of the dust-containing air flowing through the inflow air passage 31 reaches the bypass inlet 45 while changing its traveling direction upward. This dust-containing air passes through the bypass inlet 45 and flows into the first half of the bypass inlet air passage 32.

  The dust-containing air that has flowed into the bypass inflow air passage 32 moves through the C-shaped space surrounded by the side wall portion 54 and reaches the second bypass opening 57. The dust-containing air moves downward through the second bypass opening 57 and flows into the latter half of the bypass inflow air passage 32. The dust-containing air that has passed through the second bypass opening 57 moves in the groove 48. In the groove 48, the dust-containing air moves in the direction in which the air is swirling in the swirl chamber 33 (the swirling direction). The dust-containing air that has reached one end of the groove 48 passes through the auxiliary inlet 46 and flows into the swirl chamber 33.

  The traveling direction of the dust-containing air flowing into the bypass inflow air passage 32 is greatly bent inside the inflow pipe 39. Among the dust flowing through the inflow air passage 31, dust having a large inertia force, that is, relatively large dust other than fine dust, is generated from the airflow for flowing into the bypass inflow air passage 32 before reaching the bypass inlet 45. It will come off. Only fine dust having a relatively small inertial force passes through the bypass inlet 45 and flows into the bypass inflow air passage 32. Garbage other than fine dust passes through the inflow air passage 31 and is taken into the swirl chamber 33 from the main inflow port 44.

  The dust-containing air that has passed through the main inlet 44 flows into the swirl chamber 33 along the inner wall of the swirl chamber 33. Similarly, the dust-containing air that has passed through the auxiliary inlet 46 flows into the swirl chamber 33 along the inner wall of the swirl chamber 33. The dust-containing air taken into the swirl chamber 33 from the main inlet 44 and the sub-inlet 46 forms a swirl airflow that rotates in one direction along the side wall in the swirl chamber 33. The whirling airflow flows downward due to the path structure and gravity while forming a forced vortex region near the central axis and a free vortex region outside the central vortex region.

  The dust-containing air flows into the swirl chamber 33 from the main inlet 44 and the sub-inlet 46 so as to push the swirl airflow in the swirl chamber 33 sequentially from the rear. That is, the dust-containing air newly taken into the swirl chamber 33 flows into the swirl chamber 33 so as to accelerate the swirl airflow already formed in the swirl chamber 33. By providing the bypass inflow air passage 32, the turning force in the turning chamber 33 can be increased. For this reason, the function (separation performance) which isolate | separates refuse improves significantly.

  In addition, when the bypass inflow air passage 32 is provided, the flow velocity of air necessary for ensuring a predetermined turning force can be reduced as compared with the case where the bypass inflow air passage 32 is not provided. By providing the bypass inflow air passage 32, airflow noise can be suppressed, and the noise of the apparatus can be reduced.

  Centrifugal force acts on the dust flowing into the swirl chamber 33. For example, relatively large waste such as fiber waste and hair (hereinafter, such waste is also referred to as “garbage α”) falls in the swirl chamber 33 while being pressed against the inner wall of the swirl chamber 33 by the centrifugal force. . When the waste α reaches the height of the zeroth order opening 52, it is separated from the swirling airflow. The garbage α passes through the zero-order opening 52 and enters the zero-order dust collection chamber 34. The zero-order dust collection chamber 34 is provided so as to extend downward from the zero-order opening 52. Therefore, the dust α that has entered the zero-order dust collection chamber 34 from the zero-order opening 52 falls in the zero-order dust collection chamber 34 while moving in the same direction as the air swirling direction in the swirl chamber 33. Then, the garbage α reaches the lowermost part of the zero-order dust collection chamber 34 and is collected.

  Garbage that has not entered the zero-order dust collection chamber 34 from the zero-order opening 52 proceeds further downward while swirling in the swirl chamber 33. Relatively small waste such as sand waste and fine fiber waste (hereinafter, such waste is also referred to as “garbage β”) passes through the primary opening 42. And garbage (beta) falls in the primary dust collection chamber 35, and is collected.

  When the airflow swirling in the swirl chamber 33 reaches the lowermost part of the swirl chamber 33, the traveling direction is changed upward, and the airflow rises along the central axis of the swirl chamber 33. Garbage α and dust β are removed from the air that forms this updraft. The airflow (clean air) from which the waste α and the waste β are removed passes through the discharge port 58 and is discharged out of the swirl chamber 33. The air discharged from the swirl chamber 33 passes through the outflow air passage 36 and reaches the unit outlet 62. Then, the clean air sequentially passes through the unit outlet 62 and the connection port 23 and is sent to the exhaust air passage 22.

  As the electric blower 10 performs the suction operation, the dust α is accumulated in the zero-order dust collection chamber 34. The garbage β is accumulated in the primary dust collection chamber 35. The dust α and the dust β can be easily discarded by removing the dust collecting unit case 30 from the dust collecting unit 13.

  When cleaning is completed and the electric vacuum cleaner 1 is stored, the dust collection unit 13 is arranged vertically. When the dust collection unit 13 is disposed vertically, the swirl chamber 33 is disposed, for example, such that the central axis faces the vertical direction.

  When the dust collection unit 13 is disposed vertically, the bottom 49 is disposed above the connection portion 41. When the dust collection unit 13 is arranged vertically, the dust in the zero-order dust collection chamber 34 falls and moves from the space on the bottom 49 side to the space on the connection portion 41 side.

  As described above, the zero-order dust collection chamber 34 extends in the other direction along the central axis of the swirl chamber 33 (on the connection portion 41 side) from the portion where the zero-order opening 52 is formed. In the present embodiment, a case where the connection portion 41 and the portion closest to the connection portion 41 in the zero-order opening 52 are separated by a distance L is shown as an example (see FIG. 12). For this reason, when the dust collection unit 13 is arranged vertically, a space having a height L is formed between the zeroth order opening 52 and the connection portion 41 in the zeroth order dust collection chamber 34. Even when the dust collection unit 13 is disposed vertically, a part of the zero-order dust collection chamber 34 is disposed below the zero-order opening 52.

  The cyclone separation device having the above configuration reliably prevents the dust collected in the zero-order dust collection chamber 34 from entering the swirl chamber 33 even when the cyclone separation device is disposed upside down. be able to. That is, even if the dust collection unit 13 is arranged vertically, the dust in the zero-order dust collection chamber 34 can be reliably retained in the zero-order dust collection chamber 34. Even if the dust collection unit 13 is removed from the storage unit 12, dust does not spill from the dust collection unit 13.

The dust collecting unit 13 having the above-described configuration is effective for the electric vacuum cleaner 1 that is easily arranged in the vertical direction when stored.
For example, when the horizontal projection area of the cleaner body 6 when arranged vertically is smaller than the horizontal projection area of the cleaner body 6 when arranged horizontally, the cleaner body 6 is arranged vertically. Thus, the vacuum cleaner 1 can be stored in a compact manner. The dust collection unit 13 having the above configuration can be a particularly effective means in such a case.

  Even when the horizontal projection area of the vacuum cleaner main body 6 when placed sideways is small to some extent, the suction pipe 3 and the suction hose 5 may take up space when the vacuum cleaner 1 is stored. For example, when the hose connection port 9 is formed on the front surface 12a of the housing unit 12 as in the case of the electric vacuum cleaner 1, the suction hose 5 is disposed on the side of the cleaner body 6 when the cleaner body 6 is disposed sideways. Protrudes. If the hose connection port 9 opens upward when the vacuum cleaner main body 6 is arranged vertically, the suction hose 5 and the like will not interfere when the vacuum cleaner 1 is stored. The dust collection unit 13 having the above configuration can be an effective means even in such a case.

  In the present embodiment, the case where both the main inlet 44 and the auxiliary inlet 46 are provided as the inlet for taking the dust-containing air into the swirl chamber 33 has been described. This is an example. Only one inflow port may be formed on the side wall forming the swirl chamber 33.

  The distance L between the connecting portion 41 and the portion of the zero-order opening 52 that is closest to the connecting portion 41 is arbitrarily set. For example, in the zero-order dust collection chamber 34, the volume of the space (the space on the bottom 49 side) extending in one direction from the zero-order opening 52 along the central axis of the swirl chamber 33 is the space (the connection portion 41 side) extending in the other direction. The volume of the space) may be smaller.

  When the dust collection unit 13 is disposed sideways, the space on the bottom 49 side is disposed below the space on the connection portion 41 side. The dust collects in the space on the bottom 49 side when the electric blower 10 is operating. For this reason, garbage is accumulated in the space on the bottom 49 side while being compressed. On the other hand, the dust moves to the space on the connection portion 41 side when the dust collection unit 13 is arranged vertically. At this time, the garbage is not compressed. For this reason, by making the volume of the space on the connection portion 41 side larger than the volume of the space on the bottom portion 49 side, it is possible to reliably prevent dust from entering the swirl chamber 33.

  Further, if the dust in the zero-order dust collection chamber 34 does not reach the height of the zero-order opening 52 when cleaning is completed, the user can arrange the cleaner body 6 in the vertical direction with peace of mind. It is not necessary to check whether dust has entered the swirl chamber 33 after the vacuum cleaner main body 6 is arranged vertically, and the usability during transportation and storage can be improved.

Embodiment 2. FIG.

The vacuum cleaner 1 according to the present embodiment is the first embodiment in that the central axis of the swirl chamber 33 is disposed obliquely when the cleaner body 6 (dust collecting unit 13) is disposed vertically. It differs from the disclosed configuration. Further, the position where the zero-order opening 52 is formed is different from the configuration disclosed in the first embodiment.
Other configurations are the same as the configurations disclosed in the first embodiment.

  When the cleaner body 6 is disposed sideways, the bottom surface 12b of the housing unit 12 faces downward and is disposed substantially parallel to the floor surface. If the dust collection unit 13 is properly attached to the storage unit 12, the swirl chamber 33 is disposed obliquely with the central axis aligned with the inclination of the upper surface of the storage unit 12. This is the same as in the first embodiment.

  When the dust collection unit 13 is disposed sideways, the zero-order opening 52 is disposed above the central axis of the swirl chamber 33. For example, when the dust collection unit 13 is appropriately attached to the storage unit 12, the zero-order opening 52 is disposed at a position opposite to the position where the storage unit 12 is disposed with respect to the central axis of the swirl chamber 33. Is done. That is, the 0th-order opening 52 opens obliquely upward. When the dust collection unit 13 is disposed sideways, a part of the zero-order dust collection chamber 34 is disposed below the zero-order opening 52.

  When the cleaner body 6 is arranged vertically, the back surface 12c of the storage unit 12 faces downward and is arranged substantially parallel to the floor surface. In this Embodiment, the case where the bottom face 12b and the back surface 12c of the accommodating unit 12 are substantially orthogonal is shown. For this reason, when the cleaner body 6 is disposed vertically, the central axis of the swirl chamber 33 is disposed obliquely. For example, the central axis of the swirl chamber 33 has a certain value with an angle between the vertical plane and 0 ° or more and 45 ° or less (θ2 shown in FIG. 26). When the bottom surface 12b and the back surface 12c are orthogonal, θ2 = θ1.

  When the dust collection unit 13 is disposed vertically, the zero-order opening 52 is disposed above the central axis of the swirl chamber 33. The zero-order opening 52 opens obliquely to the side. Even when the dust collection unit 13 is disposed vertically, a part of the zero-order dust collection chamber 34 is disposed below the zero-order opening 52.

  The cyclone separator having the above-described configuration is sufficient to accommodate dust in the zero-order dust collecting chamber 34 in both cases where the dust collection unit 13 is disposed in the horizontal direction and in the vertical direction. Capacity can be secured.

  When the dust collection unit 13 is disposed sideways, dust can be collected in a portion of the zero-order dust collection chamber 34 disposed below the straight line K in FIG. The straight line K is a horizontal straight line that passes through the lower end of the zero-order opening 52 when the dust collection unit 13 is disposed sideways. When the dust collection unit 13 is arranged vertically, dust can be collected in a portion of the zero-order dust collection chamber 34 arranged below the straight line M in FIG. The straight line M is a horizontal straight line that passes through the lower end of the zero-order opening 52 when the dust collection unit 13 is arranged vertically.

Also in the present embodiment, each modification disclosed in the first embodiment may be applied.
For example, the horizontal projection area of the cleaner body 6 when it is arranged vertically may be smaller than the horizontal projection area of the cleaner body 6 when it is arranged horizontally. The same effects as those disclosed in the first embodiment can be obtained.

  In the first and second embodiments, the case has been described in which the dust collection unit 13 is disposed horizontally during cleaning and the dust collection unit 13 is disposed vertically during storage. The present invention can be arranged in both the direction in which the dust in the zero-order dust collection chamber 34 falls in one direction along the central axis of the swirl chamber 33 and the direction in which the dust falls in the other direction along the central axis of the swirl chamber 33. It can be applied to a cyclone separator. In the first and second embodiments, the one direction has been described as the horizontal direction, and the other direction has been described as the vertical direction.

  In the first and second embodiments, the canister type vacuum cleaner 1 has been described. The present invention can also be applied to other types of vacuum cleaners.
