Description

Electric vacuum cleaner

The present invention relates to a vacuum cleaner provided with a cyclone type dust collector.

In recent years, vacuum cleaners equipped with a cyclone type dust collecting device that separates relatively large dust by centrifugal force by swirling the sucked air in the dust collecting container and deposits it on the bottom of the dust collecting container have become widespread. Patent Document 1 discloses a related art related thereto.

The vacuum cleaner described in Patent Document 1 includes a main body with a built-in electric blower. A connection pipe is connected to the suction port facing the surface to be cleaned, and a flexible hose is connected to the main body. A cyclone type dust collector is disposed between the connection pipe and the hose at the upper end of the connection pipe.

The dust collector includes a detachable dust collecting container (dust cup) formed in a bottomed cylindrical shape having a circular cross section with an opening surface on the upper surface. Above the dust collection container, a cyclone main body is provided in which a portion of the opening surface of the upper surface of the dust collection container is fitted. The cyclone main body is provided with an inflow port (air outlet) on the peripheral surface thereof for communicating with the connection pipe and allowing air from the connection pipe to flow in the circumferential tangential direction. In the dust collecting container, a swirling airflow is formed by the air flowing from the inlet.

In the dust collection container, an inner cylinder (exhaust cylinder) having an airflow outlet (exhaust port) opened on the peripheral surface is coaxially arranged. The inner cylinder is attached so as to hang from the cyclone body, and a filter is provided at the outlet of the peripheral surface. The cyclone body communicates with a hose connected to the body of the vacuum cleaner. The dust collecting device can attach and detach the dust collecting container to the cyclone main body and the inner cylinder.

In the vacuum cleaner configured as described above, the dust on the surface to be cleaned is sucked together with the air from the suction port body by driving the electric blower. The air sucked from the suction port body flows into the dust collecting container of the dust collecting device from the inlet through the connection pipe. The air that has flowed into the dust collecting container swirls within the dust collecting container, and large dust is separated by centrifugal force and accumulated on the bottom of the dust collecting container.

When the airflow from which large dust has been removed flows into the inner cylinder through the outlet, fine dust is collected by the mesh (filter) at the outlet. The airflow from which fine dust has been removed flows out of the cyclone body, that is, the dust collector. The air flowing out from the dust collector passes through the hose and the electric blower in the main body and is exhausted to the outside. Thereby, the surface to be cleaned can be cleaned.

Dust accumulated in the dust collecting container can be discarded by removing the dust collecting container from the dust collecting device. And when removing a dust container from a dust collector, the cleaning means provided in the location corresponding to the outer peripheral surface of an inner cylinder slides the outer side of an inner cylinder, and cleans the mesh of an outflow port. Thereby, the dust adhering to the mesh can be scraped off from the mesh surface and collected in the dust collecting container.

In another conventional technique, there is an electric vacuum cleaner in which a cyclone type dust collector is disposed in front of the electric blower inside the main body.

Japanese Patent No. 3850738

However, in the conventional vacuum cleaner, when the dust container is removed from the dust collector, the ring-shaped cleaning portion stops at the bottom of the mesh portion of the inner cylinder and stays there. As a result, hair-like dust, lint, and cotton-like dust entangled with the mesh are sandwiched between the inner cylinder and the cleaning portion. These dusts cannot be separated from the surface of the mesh and can accumulate on the surface of the mesh. As a result, when the dust accumulated in the dust collecting container is discarded, it is necessary for the user to directly remove the dust accumulated on the surface of the mesh with a cleaning tool such as a brush or by hand, which is very troublesome.

Furthermore, if dust accumulates on the surface of the mesh, the momentum of the swirling airflow in the dust collecting container may be weakened. Thereby, there existed a problem that the dust collection power of a dust collector fell.

The present invention has been made in view of the above points, and can eliminate the user's annoyance when discarding the dust accumulated in the dust collecting container and can improve the dust collecting power. It aims at providing a simple vacuum cleaner.

In order to solve the above problems, a vacuum cleaner according to the present invention is a detachable dust collector that is formed in a bottomed cylindrical shape having a circular cross section with an opening surface on the upper surface and an airflow inlet is provided on the peripheral surface. A container, an inner cylinder that is arranged coaxially with the dust collecting container and opens an airflow outlet to the peripheral surface, and a mesh is provided at the outlet, and a disk portion that extends radially outward from the inner cylinder A partition member that has a cylindrical portion extending vertically from the periphery of the disc portion and forms an air flow path between the inner surface of the dust collecting container and partitions the dust collecting container up and down, An electric vacuum cleaner provided with a cyclone type dust collecting device that swirls an airflow flowing into the dust collecting container from an inflow port to drop the dust into the dust collecting container, wherein the partition member is disposed on the inner cylinder. Along with the outer peripheral surface of the inner cylinder, it is detachably provided. It is characterized in that provided as integrally with the partition member cleaning unit that slides the positions of the outer circumferential surface of the inner tube when in proximity to detach the partition member from the inner cylinder Te.

According to this configuration, by removing the partition member from the inner cylinder, the cleaning unit slides on the outside of the inner cylinder and cleans the surface of the mesh at the outlet. Accordingly, there is no possibility that dust in the form of fibers such as hair, lint, or cotton entangled with the mesh is caught between the inner cylinder and the cleaning unit. These dusts are prevented from accumulating on the surface of the mesh.

Further, in the vacuum cleaner having the above-described configuration, the partition member includes a claw portion that is detachably engaged with the inner cylinder, and the inner cylinder locks the claw portion of the partition member. It is characterized by comprising a locking groove formed continuously over the outer peripheral surface of the inner cylinder.

According to this configuration, the partition member engages with any portion in the circumferential direction of the inner cylinder via the claw portion. Therefore, the user's troublesomeness when discarding the dust accumulated in the dust collecting container is further eliminated.

Further, in the electric vacuum cleaner having the above-described configuration, the partition member includes a column portion extending along an outer peripheral surface of the inner cylinder from the disk portion to the cleaning section in order to support the cleaning section, and the inner cylinder includes A frame portion that divides the outflow port into a plurality of portions, and a circumferential direction of the claw portion in the locking groove at a location where the locking groove overlaps the column portion with the frame portion in the radial direction of the inner cylinder It is characterized by including a stopper portion that provides resistance to movement.

According to this configuration, when the claw portion is engaged with the position of the stopper portion of the locking groove, the frame portion of the inner cylinder and the support column portion of the partition member overlap in the radial direction of the inner cylinder. Therefore, since the outlet of the inner cylinder and the column portion of the partition member do not overlap with each other in the radial direction of the inner cylinder, a reduction in the dust collecting force of the dust collector is prevented.

Further, in the vacuum cleaner having the above-described configuration, the partition member is attached to the dust collector of the dust container and the partition member comes into contact with the inner bottom surface of the dust container and is removed from the inner cylinder. In order to attach to the inner cylinder, a protruding portion extending from the disk portion toward the inner bottom surface of the dust collecting container is provided.

According to this configuration, even when the partition member is not sufficiently attached to the inner cylinder, the attachment of the partition member to the inner cylinder is completed together with the dust container being attached to the dust collector. Therefore, the problem of mounting the partition member on the inner cylinder is solved, and the reduction of the dust collecting power of the dust collecting device is prevented.

Further, in the electric vacuum cleaner having the above-described configuration, the cleaning unit is configured in a ring shape that is close to the outer peripheral surface of the inner cylinder and holds the inner cylinder in the radial direction.

This configuration improves the strength of the cleaning part. Therefore, since the cleaning capability of the cleaning portion with respect to the inner cylinder is improved, the action of preventing the fibrous dust from accumulating on the surface of the mesh at the outlet is further improved.

According to the configuration of the present invention, the dust that forms fibers such as hair, lint, and cotton entangled with the mesh at the outlet is not caught between the inner cylinder and the cleaning unit, and the dust is Is prevented from depositing. Accordingly, it is possible to provide a vacuum cleaner that can eliminate the troublesomeness of the user when the dust accumulated in the dust collecting container is discarded and can improve the dust collecting power.

The dust collector 20 and the electric blower 6 are connected by a duct 12.

On the upper part of the dust collecting device 20, a cover portion 21 that is continuous with the main body cover 11 and forms the exterior of the main body portion 2 is provided. On the upper surface of the cover portion 21, a grip portion 21a that is gripped by the user is provided. The dust collector 20 is detachable from the main body 2 by gripping and lifting the grip 21 a.

As shown in FIGS. 2 and 3, the dust collecting device 20 includes a cover part 21, a dust collecting container 22, a filter holding part 23, a dust removing part 24, an inner cylinder 30, and a partition member 40.

The dust collecting container 22 is made of a transparent resin, and is disposed at the lower part of the dust collecting device 20. The dust collecting container 22 is formed in a bottomed cylindrical shape with a circular cross section having an opening surface 22a on the upper surface. The front peripheral surface of the dust collecting container 22 is provided with an inflow port 22b formed so as to extend in the circumferential tangential direction. The inflow port 22b communicates with the connection port 11a and the airflow from the connection hose 3 (see FIG. 1) flows in. An airflow flows into the dust collecting container 22 in a circumferential tangential direction through the inlet 22 b, and a swirling airflow is formed in the dust collecting container 22. Thereby, the cyclone type dust collector 20 is formed, and dust contained in the airflow is separated and removed by centrifugal force and collected.

The filter holding unit 23 is disposed above the dust collecting container 20 and above the dust collecting device 20. The filter holding unit 23 holds a filter 23a formed by a pleated filter or the like. The filter 23 a has a circular shape in plan view and is arranged coaxially with the dust collection container 22. The entire upper surface of the filter holding part 23 is covered with the cover part 21 and communicates with a dust collector exhaust port 21 b provided at the rear part of the cover part 21. The dust collector exhaust port 21b communicates with a duct 12 provided between the dust collector 20 and the electric blower 6, and an airflow from which dust is removed by the dust collector 20 flows out.

The dust removing unit 24 is provided at a location on the upper surface of the filter holding unit 23 and includes a vibration unit 24a. The vibration unit 24a is disposed above the filter 23a, and is rotatable about an axis that is coaxial with the filter 23a. The vibration part 24a abuts on the top of the pleats of the filter 23a while rotating and moving along the circumferential direction of the filter 23a by a motor or manually. The dust removing unit 24 rotates the vibrating unit 24a so that the vibrating unit 24a sequentially repels the top of the filter 23a to vibrate the filter 23a, and removes and removes dust adhering to the surface.

The inner cylinder 30 is provided so as to protrude from the lower surface of the filter holding portion 23 into the dust collecting container 22 below. The inner cylinder 30 is arranged coaxially with the dust collection container 22, and an air outlet 31 of the air flow in the dust collection container 22 is opened on the peripheral surface. The airflow swirling in the dust collection container 22 flows out of the dust collection container 22 through the outlet 31 and reaches the filter 23a.

The partition member 40 is provided outside and below the inner cylinder 30. The partition member 40 is provided detachably with respect to the inner cylinder 30. The partition member 40 forms an air flow path between the inner surface of the dust collection container 22 and partitions the inside of the dust collection container 22 up and down.

In the vacuum cleaner 1 having such a configuration, when the electric blower 6 is driven by a switch operation of the operation unit 10, air containing dust is sucked from the suction port body 5. The air sucked from the suction port body 5 flows into the dust collecting device 20 and the dust collecting container 22 through the extension pipe 4 and the connection hose 3 and through the inlet 22b. At this time, the dust sucked together with the air is separated from the air flow by the centrifugal force of rotation and collected in the dust collecting container 22.

The air guided into the dust collecting container 22 flows out from the outlet 31 and passes through the filter holder 23 through the inner cylinder 30. At this time, relatively fine dust that has not been separated in the dust collection container 22 is collected on the upstream (downside) surface of the filter holding unit 23 in the air flow direction, and falls into the dust collection container 22 or the filter holding unit 23. Adhere to the surface. The air that has passed through the filter holder 23 flows out of the dust collector 20 through the dust collector exhaust port 21b.

Subsequently, detailed configurations of the inner cylinder 30 and the partition member 40 will be described with reference to FIGS. 4 to 8 in addition to FIG. 4 is a vertical sectional side view of the inner cylinder 30 and the partition member 40, and FIG. 5 is a perspective view of the inner cylinder 30 and the partition member 40, showing a state in which the partition member 40 is removed from the

inner cylinder

30, 6 is a vertical cross-sectional side view showing an engagement portion of the inner cylinder 30 and the partition member 40, FIG. 7 is a horizontal cross-sectional partial plan view showing a locking groove of the inner cylinder 30, and FIG. 8 is a perspective view of the inner cylinder 30 and the partition member 40. The state which attached the partition member 40 with respect to the inner cylinder 30 is shown in figure.

The inner cylinder 30 includes an outlet 31, a frame part 32, a mesh 33 and a locking groove 34 as shown in FIGS. 4 and 5.

The outlet 31 is divided into a plurality of frames 32. The frame portion 32 extends in the vertical direction to form a plurality of vertically long rectangular outlets 31. The frame portion 32 includes a frame portion 32 a having a relatively wide width and a frame portion 32 b having a relatively narrow width in the circumferential direction of the inner cylinder 30. Four wide frame portions 32 a are provided along the circumferential direction of the inner cylinder 30 at least every 90 °.

The outlet 31 is provided with a mesh 33 for collecting dust. The mesh 33 is provided on the outer peripheral surface or inner peripheral surface of the inner cylinder 30 so as to cover the outlet 31.

The locking groove 34 is provided at the lower part of the outer peripheral surface of the inner cylinder 30 as shown in FIGS. The locking groove 34 is formed by a concave portion that is recessed inward in the radial direction, and is formed continuously over the entire outer peripheral surface of the inner cylinder 30. When the partition member 40 is attached to the inner cylinder 30, the locking groove 34 of the inner cylinder 30 locks a claw portion 46 described later of the partition member 40.

As shown in FIGS. 4 and 5, the partition member 40 includes a disk part 41, a cylindrical part 42, a protruding part 43, a cleaning part 44, a column part 45, and a claw part 46.

The disc portion 41 is formed in a disc shape extending from the lower end of the inner cylinder 30 toward the radially outer side. The cylindrical portion 42 is formed in a cylindrical shape extending upward and downward from the periphery of the disc portion 41.

The protruding portion 43 communicates with the inner cylinder 30 and protrudes downward from the lower surface of the disc portion 41 and extends toward the inner bottom surface of the dust collecting container 22. When the partition member 40 is attached to the inner cylinder 30 and the dust collecting container 22 is attached to the dust collecting device 20, the projecting portion 43 is configured to just contact the inner bottom surface of the dust collecting container 22. That is, the protrusion 43 brings the partition member 40 into contact with the inner bottom surface of the dust collection container 22 while the dust collection container 22 is attached to the dust collector 20, and the partition member 40 removed from the inner cylinder 30 is attached to the inner cylinder 30. Install it against.

The projecting portion 43 having such a configuration forms a columnar portion having a circular cross section standing at the center in the radial direction below the partition member 40, and the airflow can be smoothly swung around the columnar portion. Further, the fine dust that has fallen into the inner cylinder 30 from the filter 23 a by the dust removal of the filter 23 a (see FIG. 2) by the dust removing portion 24 is collected inside the protruding portion 43. The protrusion 43 prevents fine dust from flowing into the airflow in the dust collecting container 22.

The cleaning unit 44 is supported by a support column 45 that extends upward from the upper surface of the disk unit 41, and is configured to be close to the outer peripheral surface of the inner cylinder 30. The cleaning unit 44 is formed in, for example, a ring shape that is close to the outer peripheral surface of the inner cylinder 30 and holds the inner cylinder 30 radially inward. The cleaning unit 44 slides on the outer peripheral surface of the inner cylinder 30 when the partition member 40 is removed from the inner cylinder 30. A brush-like member that contacts the surface of the mesh 33 of the inner cylinder 30 may be provided on the inner peripheral surface of the cleaning unit 44. Moreover, the cleaning part 44 may be comprised with the some circular-arc-shaped member arrange | positioned so that the circumference | surroundings of the inner cylinder 30 may be enclosed.

The column part 45 extends along the outer peripheral surface of the inner cylinder 30 upward from the upper surface of the disk part 41 to the cleaning part 44 in order to support the cleaning part 44. Four struts 45 are provided every 90 ° along the circumferential direction of the inner cylinder 30. Then, when the partition member 40 attached to the inner cylinder 30 is rotated in the circumferential direction, all the column portions 45 and the frame portion 32a of the inner cylinder 30 can be brought into an overlapping state in the radial direction of the inner cylinder (see FIG. 8). The column portion 45 is substantially the same width as the frame portion 32a in the circumferential direction of the inner cylinder 30, or slightly narrower than the frame portion 32a.

As shown in FIGS. 4 to 6, the claw portion 46 is provided on the upper surface of the disc portion 41 and at a position corresponding to the outer peripheral surface of the lower end of the inner cylinder 30. The claw portion 46 protrudes upward from the upper surface of the disc portion 41 and can be displaced in a radial direction of the inner cylinder 30, that is, a direction approaching or separating from the outer peripheral surface of the inner cylinder 30 by elastic deformation. The claw portion 46 engages with the locking groove 34 of the inner cylinder 30 in a so-called snap-fit structure so that the partition member 40 can be freely attached to and detached from the inner cylinder 30.

Here, the locking groove 34 is provided with a stopper portion 34a shown in FIG. 7 in at least one place in the circumferential direction. On both sides of the stopper portion 34a in the circumferential direction, there are provided steps 34b such that the stopper portion 34a has a size that can just accommodate the claw portion 46 in the circumferential direction. A slope 34c is formed with respect to the inner peripheral surface of the locking groove 34 on the outer side in the circumferential direction with respect to the stopper portion 34a of each of the two steps 34b.

Accordingly, when the partition member 40 attached to the inner cylinder 30 is rotated so that the claw portion 46 engaged with the locking groove 34 on the outer side in the circumferential direction of the stopper portion 34a is moved toward the stopper portion 34a, the claw portion 46 is rotated. Moves while elastically deforming radially outward at the position of the slope 34c, exceeds the step 34b, and fits in the stopper portion 34a. When the claw portion 46 is accommodated in the stopper portion 34a, the stopper portion 34a becomes resistance to movement of the claw portion 46 in the circumferential direction in the locking groove 34 by the action of the step 34b. However, when the partition member 40 is rotated in the circumferential direction with respect to the inner cylinder 30 with a sufficient force while the claw portion 46 is accommodated in the stopper portion 34a, the claw portion 46 is elastically deformed radially outward to form the step 34b. It is removed from the stopper part 34a.

The stopper portion 34a moves in the circumferential direction of the claw portion 46 in the locking groove 34 at a position where the column portion 32 of the partition member 40 overlaps the frame portion 32a of the inner tube 30 in the radial direction of the inner tube 30. It becomes resistance. That is, when the claw portion 46 is engaged with the locking groove 34 and accommodated in the stopper portion 34a, all the column portions 45 and the frame portion 32a can be overlapped in the radial direction of the inner cylinder as shown in FIG. (See FIG. 8).

As described above, in the electric vacuum cleaner 1 provided with the cyclone type dust collecting device 20, the partition member 40 is detachably provided to the inner cylinder 30. Further, a cleaning unit 44 configured to be close to the outer peripheral surface of the inner cylinder 30 and sliding on the outer peripheral surface of the inner cylinder 30 when the partition member 40 is removed from the inner cylinder 30 is integrated with the partition member 40. It is provided as. Thereby, by removing the partition member 40 from the inner cylinder 30, the cleaning unit 44 slides outside the inner cylinder 33 to clean the surface of the mesh 33 of the outlet 31. Therefore, hair, lint, and cotton-like dust that is entangled with the mesh 33 is not caught between the inner cylinder 30 and the cleaning unit 44. These dusts can be prevented from accumulating on the surface of the mesh 33. As a result, when the vacuum cleaner 1 discards the dust accumulated in the dust collecting container 22, it is not necessary for the user to directly remove the dust accumulated on the surface of the mesh 33, and the troublesomeness can be eliminated.

Further, the vacuum cleaner 1 includes a claw portion 46 for the partition member 40 to be detachably engaged with the inner cylinder 30, and the inner cylinder 30 is configured to lock the claw portion 46 of the partition member 40. 30 is provided with a locking groove 34 formed continuously over the entire circumference of 30 outer peripheral surfaces. As a result, the partition member 40 is engaged via the claw portion 46 with respect to any location in the circumferential direction of the inner cylinder 30. Therefore, the vacuum cleaner 1 can further eliminate the troublesomeness of the user when the dust accumulated in the dust collecting container 22 is discarded.

Further, the vacuum cleaner 1 includes a column portion 45 that extends along the outer peripheral surface of the inner cylinder so that the partition member 40 supports the cleaning portion 44, and the inner cylinder 30 includes a frame portion 32 a that divides the outlet 31. I have. A stopper portion 34a that serves as a resistance to movement of the claw portion 46 in the circumferential direction in the locking groove 34 at a position where the locking groove 34 overlaps the column portion 45a with the frame portion 32a in the radial direction of the inner cylinder 30 is provided. I have. Accordingly, when the claw portion 46 is engaged with the position of the stopper portion 34 a of the locking groove 34, the frame portion 32 a of the inner cylinder 30 and the column portion 45 of the partition member 40 overlap with each other in the radial direction of the inner cylinder 30. . Therefore, the vacuum cleaner 1 can prevent the outflow port 31 of the inner cylinder 30 and the column part 45 of the partition member 40 from overlapping with respect to the radial direction of the inner cylinder 30, and the dust collecting power of the dust collector 20 is reduced. Can be disturbed.

In addition, the vacuum cleaner 1 attaches the partition member 40 to the inner cylinder 30, which is detached from the inner cylinder 30 by the partition member 40 coming into contact with the inner bottom surface of the dust container 22 as the dust collector 22 is attached to the dust collector 20. In order to be mounted, a projecting portion 43 extending from the disc portion 41 toward the inner bottom surface of the dust collecting container 22 is provided. Thereby, even if the mounting of the partition member 40 to the inner cylinder 30 is insufficient, the mounting of the partition member 40 to the inner cylinder 30 is completed together with the mounting of the dust collecting container 22 to the dust collector 20. Therefore, the vacuum cleaner 1 can solve the problem of mounting the partition member 40 on the inner cylinder 30, and can prevent a decrease in the dust collecting power of the dust collecting device 20.

Furthermore, since the vacuum cleaner 1 is configured in a ring shape in which the cleaning part 44 is close to the outer peripheral surface of the inner cylinder 30 and holds the inner cylinder 30 radially inward, the strength of the cleaning part 44 is improved. Therefore, the cleaning capability of the cleaning unit 44 with respect to the inner cylinder 30 can be improved. As a result, it is possible to further improve the action of preventing the fibrous dust from accumulating on the surface of the mesh 33 of the outlet 31.

And according to the structure of the said embodiment of this invention, the dust which makes | forms fibrous forms, such as the hair, the thread waste, and cotton which were entangled with the mesh 33 of the outflow port 31, is pinched | interposed between the inner cylinder 33 and the cleaning part 44. This prevents the dust from accumulating on the surface of the mesh 33. Therefore, it is possible to provide the vacuum cleaner 1 that can eliminate the troublesomeness of the user when the dust accumulated in the dust collecting container 22 is discarded and can improve the dust collecting power.

The embodiment of the present invention has been described above, but the scope of the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention.

For example, the vacuum cleaner 1 is a so-called canister type in which the suction port body 5 is connected to the main body portion 2 including the electric blower 6 via the connection hose 3.
