Description

  The present invention relates to a vacuum cleaner provided with a dust collecting container that separates dust by a swirling airflow.

  A conventional vacuum cleaner is disclosed in Patent Document 1. In this vacuum cleaner, a dust collection container is detachably provided on an extension pipe connected to the suction port body. The dust collecting container is formed in a bottomed cylindrical shape having an open upper surface, and an inflow port through which airflow flows in a tangential direction from the extension pipe is provided on the peripheral surface. The extension pipe is provided with a cylindrical inner cylinder arranged on the central axis of the dust collecting container. The inner cylinder is provided with an opening having a filter on the peripheral surface, and communicates with the extension pipe via an outlet opening at the upper end.

  Air containing dust is sucked from the suction port body by driving the electric blower, flows through the extension pipe, and flows into the dust collecting container from the inlet. The air flowing into the dust collecting container swirls in the dust collecting container, and the dust is separated by centrifugal force. The air from which the dust has been separated flows into the inner cylinder from the opening and flows out through the outlet. The air flowing out from the outlet is exhausted to the outside through the extension pipe and the electric blower.

  Moreover, the cleaning member which an inner cylinder fits in is provided in the upper surface of a dust collecting container. When the dust collecting container is detached from the extension pipe integral with the inner cylinder, the cleaning member slides on the filter of the opening, and dust attached to the filter is removed. Then, the dust collecting container is transported, the cleaning member is removed, and the dust in the dust collecting container is discarded.

This prevents the dust from falling when the dust collection container is detached and transported, and the cleaning member can be removed together with the lid without the user touching the cleaning member. Therefore, a sanitary vacuum cleaner can be obtained.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a vacuum cleaner according to an embodiment. The electric vacuum cleaner 1 includes a main body 2 in which an electric blower 6 (see FIG. 2) is housed. An extension pipe 4 of a resin molded product is connected to the suction port body 5 facing the floor surface, and the main body 2 and the extension pipe 4 are connected by a flexible connection hose 3.

  FIG. 2 shows a longitudinal sectional view of the main body 2. An electric blower 6 is disposed below the main body 2, and a dust collecting container 10 is disposed above the electric blower 6. The dust collection container 10 is detachable by being pulled out above the main body 2 and is provided with an inlet 10a that communicates with the connection hose 3 (see FIG. 1) and allows airflow to flow in the tangential direction of the peripheral surface.

  The dust collection container 10 is formed in a bottomed cylindrical shape having a circular cross section, and the central axes of the dust collection container 10 and the electric blower 6 are inclined and arranged in a substantially straight line. An upper surface opening 10 b is opened on the upper surface of the dust collecting container 10, and the upper surface opening 10 b is closed by a detachable lid 13. A cleaning member 14 is integrally attached to the lid 13.

  An inner cylinder 11 formed integrally with the dust collection container 10 is erected at the center of the dust collection container 10. The upper end of the inner cylinder 11 is closed. An opening 11 a is formed on the peripheral surface of the inner cylinder 11, and the lower end penetrates the bottom surface of the dust collecting container 10 to form an outlet 11 b. A mesh-shaped filter 12 is provided in the opening 11a.

  A sponge-like dust collection filter 15 is disposed below the outflow port 11b. The dust collection filter 15 is held by a filter case 15 a integrated with the dust collection container 11 and faces the bottom surface of the dust collection container 10. The filter case 15a is movably attached toward the upper side in the axial direction of the dust collection container 110, and a projection 10c formed of a plurality of annular ribs projects downward on the bottom surface of the dust collection container 10.

  FIG. 3 shows a front sectional view of the dust collecting container 10 with the lid 13 removed. 4 shows a side cross-sectional view as viewed from the direction A in FIG. A packing 13a is provided on the periphery of the lid body 13, and the dust collecting container 10 has a step portion 10d formed on the periphery of the upper surface opening 10b. Thereby, the packing 13a contacts the surface facing the packing 13a of the stepped portion 10d, and the upper surface opening 10b is sealed.

  The cleaning member 14 is formed in an annular brush shape that slides on the filter 12 of the inner cylinder 11, and is held by the housing 14a. The housing 14 a is provided with a plurality of shafts 14 b that extend upward and are connected to the lid 13. Thereby, the cover body 13 and the cleaning member 14 are integrated. A groove 11c into which the shaft 14b is fitted is formed on the peripheral surface of the inner cylinder 11. The lid 13 is attached to and detached from the dust collecting container 10 by guiding the shaft 14b into the groove 11c. At this time, the cleaning member 14 slides on the filter 12 as shown in FIG.

  In the vacuum cleaner 1 configured as described above, when the electric blower 6 is driven, air containing dust is sucked from the suction port body 5 and guided to the dust collecting container 10 via the extension pipe 4 and the connection hose 3. The airflow flowing into the dust collecting container 10 from the inflow port 10a turns and dust is separated by centrifugal force.

  The air from which the dust has been separated flows into the inner cylinder 11 through the filter 12 in the opening 11a. At this time, fine dust contained in the airflow is collected by the filter 12. The air flowing through the inner cylinder 11 passes through the dust collection filter 15 through the outlet 11b. Thereby, fine dust that has not been separated in the dust collecting container 10 is collected by the dust collecting filter 15. The air that has passed through the dust collection filter 15 is guided to the electric blower 6 and exhausted to the outside.

  The dust collection filter 15 is opposed to the bottom surface of the dust collection container 10 through the gap 10 (see FIG. 2) by the protrusion 10c. For this reason, the airflow spreads from the outlet 11b due to the gap D, and the dust can be collected by the dust collection filter 15 having a wider cross-sectional area than the outlet 11b. Therefore, maintenance due to clogging of the dust collection filter 15 can be reduced. Each annular protrusion 10c is provided with a notch or a hole for allowing airflow to flow from the inner peripheral side to the outer peripheral side.

  When dust accumulates in the dust container 10, the dust container 10 is detached from the main body 2 and transported to a disposal place, and the lid 3 is removed. At this time, the cleaning member 14 slides on the filter 12 and the dust attached to the filter 12 falls into the dust collecting container 10. And the dust in the dust container 10 is discarded. When the lid 13 is attached, the cleaning member 14 slides again with the filter 12 and dust remaining on the filter 12 is removed. The dust container 10 with the lid 13 is attached to the main body 2.

  Further, the dust collection filter 15 in which fine dust is accumulated is washed with water. At this time, the filter case 15a is moved up and down. As a result, the sponge-like dust collection filter 15 repeats the expanded state shown in FIG. 1 and the state reduced by the pressing of the protrusion 10c as shown in FIG. Accordingly, dust that has entered the dust collection filter 15 can be easily removed, and the dust collection filter 15 can be drained easily.

  According to this embodiment, the inner cylinder 11 has the outflow port 11 b that passes through the bottom surface of the dust collection container 10 and opens the lower end, and covers the cover 13, the filter 12, and the slide that covers the upper surface opening 10 b of the dust collection container 10. The moving cleaning member 14 is integrally provided. Thus, when removing and transporting the dust collecting container 10, the dust is prevented from falling from the upper surface opening 10 b, and the filter 12 is cleaned by attaching and detaching the cleaning member 14 without the user touching the cleaning member 14. can do. Therefore, the vacuum cleaner 1 which can clean the filter 12 hygienically and easily can be obtained.

  Moreover, since the dust collecting filter 15 integral with the dust collecting container 10 is provided below the outlet 11b, failure of the electric blower 6 due to the dust that has passed through the filter 12 flowing into the electric blower 6 can be reduced. . Moreover, the dust which falls from the inner surface of the filter 12 at the time of conveyance of the dust collecting container 10 is collected, fall is prevented, and the more sanitary vacuum cleaner 1 can be obtained.

  Although the upper surface of the inner cylinder 11 is closed, it may be opened and closed by the lid body 13. Thereby, the dust on the dust collection filter 15 can be discarded through the inner cylinder 11. Further, when the dust collection filter 15 is expanded and contracted by the movement of the filter case 15a, the dust that has entered the inside of the dust collection filter 15 can be exposed to the surface and discarded.

  Moreover, the electric blower 6 and the dust collecting container 10 may be arranged side by side in the horizontal direction and connected via a duct. However, when the central axes of the dust collection container 10 and the electric blower 6 are arranged on a substantially straight line as in the present embodiment, the air flow path between the dust collection container 10 and the electric blower 6 can be shortened. As a result, the pressure loss can be reduced to increase the dust absorption capability, and the main body 2 can be downsized.

  Moreover, since the heavy electric blower 6 is disposed below the dust collection container 10, the main body 2 can stably prevent the overturn. In addition, since the central axes of the dust collection container 10 and the electric blower 6 are inclined, the main body 2 can be formed lower and more stable.
