[0010] Hereinafter, an electric vacuum cleaner according to the present invention will be described with reference to the drawings. FIG. 1 is an external perspective view showing an electric vacuum cleaner according to an embodiment of the present invention. As shown in FIG. 1, the electric vacuum cleaner 1 is made up of a vacuum cleaner main body 2, an extension tube 3, and a suction mouth body 4.

[0011] The vacuum cleaner body 2 includes an electric blower 5 that generates suction force inside, a first dust collection section (first dust case) 20 that stores dust collected by the suction force of the electric blower 5, and a handle 12. The handle 12 is provided with a hand-operated switch 11 and the like.

[0012] The vacuum cleaner body 2 also includes a dust collection pipe 14 connected to the first dust collection section 20. The dust collection pipe 14 communicates with a connection port 13 of the vacuum cleaner body 2. One end of an extension tube 3 is connected to the connection port 13 of the vacuum cleaner body 2, and the other end of the extension tube 3 is connected to the suction body 4. Therefore, dust and air sucked through the suction body 4 pass through the extension tube 3, enter the vacuum cleaner body 2 from the connection port 13, and flow from the dust collection pipe 14 to the first dust collection section 20. The extension tube 3 also includes a power supply terminal (not shown) to which power is supplied from the vacuum cleaner body 2.

[0013] When the hand-operated switch 11 is operated, a main body control circuit (not shown) provided in the vacuum cleaner main body 2 controls the operation and stopping of the electric blower 5 (see FIG. 1), switching the suction power, and the operation and stopping of the electric motor (not shown) provided in the suction mouth body 4. The power source for driving the vacuum cleaner main body 2 and the suction mouth body 4 is a rechargeable battery 15. This rechargeable battery 15 is provided in the vacuum cleaner main body 2 so that it can be attached and detached freely.

[0014] Fig. 2 is a perspective view of first dust collecting unit 20 removed from vacuum cleaner body 2. Fig. 3 is a perspective view of first dust collecting unit 20 as seen from the top side of vacuum cleaner 1, opposite to Fig. 2. 2, the first dust collecting section 20 is made up of a lid 21 (side wall) and a container 22. One end (upper side) of the lid 21 is provided with hinges 23, 23 that are supported so as to be openable and closable relative to the container 22. The other end (lower side) of the lid 21 is provided with a clamp 24 that fastens the lid 21 to the container 22.

[0015] As shown in Figure 3, on the hinge portion 23 side of the container 22, there are provided a dust collection section outlet 25 that communicates with the electric blower inlet 16 (see Figure 1) of the vacuum cleaner main body 2 (see Figure 1), and a main body locking section 26 that is locked to the vacuum cleaner main body 2.

[0016] Dust collection unit outlet 25 is provided with airtight surface 25a on which a rubber member such as an elastomer is insert-molded. When first dust collection unit 20 is attached to vacuum cleaner body 2 (see FIG. 1), airtight surface 25a of dust collection unit outlet 25 and electric blower inlet 16 are connected in an airtight state.

[0017] The lid 21 is also provided with an airtight packing 21a (see FIG. 4) that contacts the edge of the container 22. The airtightness of the first dust collecting section 20 is ensured when the lid 21 is closed and in close contact with the container 22 by the clamp section 24. In this embodiment, the airtight packing 21a (see FIG. 4) is provided on the lid 21, but the airtight packing may also be provided on the container 22 side.

[0018] Lid 21 has inlet 21b that communicates with dust collection section pipe 14 (see FIG. 1) provided in vacuum cleaner body 2, and hook 21c for fixing to vacuum cleaner body 2. When hook 21c is hooked onto hook 17 (see FIG. 1) of vacuum cleaner body 2 and first dust collection section 20 is tilted toward vacuum cleaner body 2, first dust collection section 20 is fixed to vacuum cleaner body 2 by body lock 26 provided in first dust collection section 20.

[0019] FIG. 4 is a perspective view of the first dust collecting section 20 with the cover 21 open. As shown in Figure 4, the container 22 of the first dust collection unit 20 is configured to accommodate a paper carton 50. The container 22 is provided with an arm 55 for mounting the paper carton 50 and a paper carton holder 56 for fixing the paper carton 50 to the arm 55. The paper carton 50 is made up of a paperboard 52 forming an opening 51 and a bag 53 for containing dust. The paperboard 52 is inserted into the arm 55 described above. The bag 53 is made of nonwoven fabric or the like and has a filtering function.

[0020] The cover 21 has a paper pack connection part 27 at approximately the center thereof, which connects to the opening 51 of the paper pack 50. The paper pack connection part 27 has an opening 28 at approximately the center thereof, and a packing 27a around the periphery of the opening 28.

[0021] Opening 28 of paper pack connecting portion 27 communicates with inlet 21b (see Figures 2 and 3) provided on the outer surface of lid body 21. Inlet 21b is not located approximately in the center of lid body 21, so inlet 21b and opening 28 communicate with each other via lid flow path 29.

[0022] The inlet 21b is located to the right or left of the center of the lid body 21 (side wall) (in this embodiment, it is located to the right of the center), in order to generate a cyclone flow when the second dust collection section 100 described later is attached and used.

[0023] The opening 51 of the paper bag 50 and, accordingly, the opening 28 of the first dust collecting unit 20 are located approximately in the center so that dust can flow in from the center and spread evenly inside the paper bag 50, thereby efficiently collecting dust inside the paper bag 50. "Approximately in the center" means that the opening 51 is located to correspond to the opening 28, which is located approximately in the center of the lid 21 in the left-right and up-down directions. Therefore, the inlet 21b and the opening 28 (opening 51) are located in different places on the side of the dust collecting unit facing the vacuum cleaner body 2, so that both the first dust collecting unit 20 that can accommodate the paper bag 50 and the second dust collecting unit (cyclone-type dust collecting unit) 100 (see FIG. 12) that separates and collects dust inside the dust case by cyclone flow can be installed.

[0024] FIG. 5 is a perspective view showing a state in which the paper pack is lifted up from the dust collecting unit shown in FIG. As shown in FIG. 5, the arm 55 is pivotally supported on the container 22 and rises upward from the shaft 55a. When the paper carton 50 is placed inside as shown in FIG. 4, the paper carton holding portion 56 contacts the stopper 60 so that the paper carton 50 (paperboard 52) is held substantially horizontally. As a result, when the lid 21 is closed, the packing 27a provided on the paper carton connecting portion 27 and the paperboard 52 of the paper carton 50 come into contact to maintain airtightness. The arm 55 may be provided with a spring on the shaft 55a so that the arm 55 rises when the lid 21 is opened. By providing a spring, the arm 55 is biased by the spring so that it rises when the lid 21 is closed, and the paperboard 52 is pressed against the packing 27a provided on the paper carton connecting portion 27, thereby improving airtightness.

[0025] Fig. 6 is a perspective view of the paper pack 50 removed from the arm 55, and Figs. 7 and 8 show the removed paper pack 50. Fig. 7 shows the paper pack 50 with the paper pack holding part 56 attached, and Fig. 8 shows the paper pack 50 alone. As shown in Fig. 6, the container 22 of the first dust collecting section 20 is provided with the stopper 60 described above and a flow straightening wall 70 on the opposite side of the stopper 60 (on the dust collecting section outlet 25 side). In this embodiment, the stopper 60 has vertical ribs, but since the purpose is to keep the paper pack 50 horizontal, horizontal ribs may also be used.

[0026] The flow straightening wall 70 is formed in a plate shape and is formed so as to extend across the left and right side surfaces of the container 22. In addition, a notch 80 is formed in the lower part (bottom side of the container 22) of the flow straightening wall 70. The area of ​​this notch 80 is equal to or larger than the dust collection section outlet 25.

[0027] As shown in Figures 7 and 8, the paper carton 50 is made up of a paperboard 52 that forms an opening 51 and a bag body 53 that collects dust, and the paperboard 52 has a hole 52a (see Figure 8). This hole 52a is provided to secure and hold the paper carton 50 in a predetermined position in the paper carton holding part 56. When the paperboard 52 of the paper carton 50 is inserted into the paper carton holding part 56, a protrusion 57 (see Figure 9) of the paper carton holding part 56 fits into the position of the hole 52a provided in the paperboard 52. The paper carton holding part 56 also has a handle 58 (see Figure 7) to make it easier to lift the paper carton 50. Having such a paper carton holding part 56 has the effect of making it easier to remove the paper carton 50.

[0028] Next, the flow of dust and air when they are sucked in in the first dust collecting section 20 of this embodiment will be described with reference to the cross-sectional view of Fig. 9. Fig. 9 is a cross-sectional view taken along the line AA shown in Fig. 2. As shown in FIG. 9, when the vacuum cleaner 1 starts operating, the air (see the bold arrow) passes through the suction body 4 (see FIG. 1), the extension tube 3 (see FIG. 1), and the dust collection pipe 14 (see FIG. 1) and enters the first dust collection section 20 through the inlet 21b. The air that enters through the inlet 21b passes through the cover flow path 29 and enters the paper bag 50 through the opening 28 (see FIG. 4). A flow straightening wall 70 is provided to prevent the air that has passed through the paper bag 50 from going directly to the dust collection section outlet 25. Therefore, the air that has passed through the paper bag 50 passes through the cutout 80 provided below the flow straightening wall 70, passes through the dust collection section outlet 25, and flows toward the electric blower 5 side (motor side) of the vacuum cleaner body 2. The flow straightening wall 70 has the effect of opening (inflating) the paper bag 50, allowing the paper bag 50 to be used effectively (to collect a large amount of dust).

[0029] As described above, by providing the paper bag 50 to the first dust collection unit 20 that is detachable from the vacuum cleaner body 2, the paper bag 50 can be easily replaced and can be disposed of without touching the dust collected in the paper bag 50. Furthermore, because the first dust collection unit 20 is detachable, the first dust collection unit 20 can be washed, which is also effective from a hygienic standpoint.

[0030] FIG. 10 is a cross-sectional view taken along the line BB shown in FIG. As shown in Fig. 10, inlet 21b and opening 28 are on different axes in the cross section taken along line BB in Fig. 3. Inlet 21b is also used in the cyclone type second dust collecting unit 100 shown in Fig. 12, and is therefore located off-center. On the other hand, opening 28 is an opening used only in the paper pack type first dust collecting unit 20, and is located approximately in the center in the cross section taken along line BB in Fig. 3 to spread the paper pack evenly and efficiently collect dust.

[0031] The vacuum cleaner 1 of this embodiment is equipped with a paper bag 50 used in conventional mobile floor (canister type) paper bag vacuum cleaners, and therefore has a large capacity for the first dust collection section 20 (see FIGS. 1 to 10). By using a ready-made paper bag 50 with a large capacity, a large amount of dust can be collected, eliminating the need to make a new dedicated paper bag.

[0032] Furthermore, for ease of use of the vacuum cleaner main body 2, a new small paper bag may be made and the first dust collecting unit 20 may be set small, but this does not change the invention of providing a paper bag in the first dust collecting unit 20 that is detachable from the vacuum cleaner main body 2.

[0033] Fig. 11 shows a state in which a second dust collecting unit 100 different from the first dust collecting unit 20 is attached to the vacuum cleaner body 2. Fig. 12 is an exploded perspective view of the second dust collecting unit according to this embodiment. Fig. 13 is a cross-sectional view of the second dust collecting unit according to this embodiment. 11, the electric vacuum cleaner 1 of this embodiment can be used by replacing the first dust collecting section 20 with the second dust collecting section 100. In other words, the electric vacuum cleaner 1 is made compatible with the first dust collecting section 20 and the second dust collecting section (cyclone dust collecting section) 100 of a conventional stick-type cyclone vacuum cleaner, allowing the user to select the dust collecting method.

[0034] 12, the second dust collecting section 100 is made up of an outer cylinder 130, an inner cylinder 140, a filter case 133 that houses the dust filter 32, and a bottom lid 131. The filter case 133 is disposed on the upper part of the outer cylinder 130, and the bottom lid 131 is disposed on the lower part. The inner cylinder 140 is provided inside the outer cylinder 130 and is concentric with the outer cylinder 130.

[0035] The outer cylinder 130 has a generally cylindrical shape with openings at the top and bottom, and is provided with an inlet portion 138 on the side through which dust-containing air (gas) flows in from the dust collection pipe 14. The dust-containing air that flows in from the inlet portion 138 is configured to become a swirling airflow along the inner circumferential surface of the outer cylinder 130. The air that flows into the outer cylinder 130 from the dust collection pipe 14 becomes an airflow around the central axis of the outer cylinder 130, and swirls inside the outer cylinder 130 around the central axis. This swirling airflow separates dust contained in the air by centrifugal force in the dust separation unit 110A (see FIG. 13).

[0036] The bottom lid 131 is rotatably attached via a hinge to the outer periphery of the outer cylinder 130. The bottom lid 131 is also provided with a mechanism for locking the bottom lid 131 to the outer cylinder 130.

[0037] The upper surface of filter case 133 has a lid structure and is divided into filter case upper part (upper lid) 133a and filter case lower part 133b. Filter case lower part 133b is formed integrally with the upper part of outer cylinder 130 and houses dust filter 132. Filter case lower part 133b and filter case upper part 133a are connected by a hinge mechanism.

[0038] The dust trapping filter 132 is pleated (mountain-folded) to increase the ventilation area, and is adhered to a circular frame 132a.

[0039] The inner cylinder 140 is substantially cylindrical and is disposed so as to be substantially concentric with the outer cylinder 130. The inner cylinder 140 is configured to include an upper inner cylinder 141 having an intake section 142 provided at the top, and an umbrella section 144 provided at the bottom.

[0040] As shown in Figure 13, the intake section (filter section) 142 of the upper inner cylinder 141 is formed by a lattice-like frame (ribs). The intake section 142 is a roughly cylindrical part. In this embodiment, the frame (ribs) extend in the vertical direction, but it may also be a lattice-like frame (ribs) in the vertical and horizontal directions. A mesh member is formed over the outer peripheral surface of the intake section 142. The upper inner cylinder 141 also has an opening 141b in the upward direction.

[0041] Umbrella portion 144 is provided in a generally cylindrical shape and is integrally and concentrically with upper inner cylinder 141. The inside of upper inner cylinder 141 and umbrella portion 144 are fluidly connected by filter portion 185. Filter portion 185 is made of a mesh member. Furthermore, umbrella portion 144 has a mechanism that slides up and down to assist in the discharge of trash when discarding.

[0042] The sliding mechanism of the umbrella portion 144 forms a spring seat in the convex portion on the underside of the upper inner cylinder 141, and the inside of the cylinder (concave portion 44d) at the center of the umbrella portion 144 serves as a support for the compression spring 147, transmitting the downward elastic force of the compression spring 147 to the umbrella portion 144. Therefore, the compression spring 147 is covered by the cylinder at the center of the umbrella portion 144. A convex portion 149 on the underside of the upper inner cylinder 141 is inserted into the concave portion 144d via the compression spring 147.

[0043] The second dust collection unit 100 has a space for separating and collecting dust between the outer cylinder 130 and the inner cylinder 140. That is, in the space formed by the outer cylinder 130 and the inner cylinder 140, a dust separation unit 110A is provided in the upper part and a dust collection unit 110B is provided in the lower part. The dust separation unit 110A is a space that separates dust from the air that carries the dust. The dust collection unit 110B is a space that collects and stores the dust.

[0044] In such a sliding mechanism, the state in which compression spring 147 is closest to its natural length is the state in which umbrella portion 144 protrudes the most from outer cylinder 130, and when bottom lid 131 is closed, compression spring 147 is compressed. Therefore, when bottom lid 131 is unlocked to dispose of trash, compression spring 147 is extended to a state close to its natural length, causing umbrella portion 144 to protrude downward and pushing out dust inside umbrella portion 144 into the external space.

[0045] When a user operates the hand-operated switch 11 (see FIG. 11) to start operation, the electric blower 5 (see FIG. 11) is activated and sucks air through the suction body 4 (see FIG. 11). The air containing dust and other particles sucked through the suction body 4 (see FIG. 11) flows into the dust collection pipe 14 (see FIG. 11) provided in the vacuum cleaner body 2 and reaches the inlet 138 (see FIGS. 11 and 12) of the second dust collection section 100. The dust separated by centrifugal force is transported by gravity and a portion of the airflow through the inlet of the dust collection section 110B (see FIG. 13) between the outer cylinder 130 and the umbrella section 144 and into the dust collection section 110B (see FIG. 13).

[0046] Because upper inner cylinder 141 and the inside of umbrella portion 144 are fluidly connected by filter portion 185, light dust such as cotton fluff and hair is carried by the flow from the inside of umbrella portion 144 toward upper inner cylinder 141, and because the downstream side of filter portion 85 (inside upper inner cylinder 141) is under negative pressure (pressure lower than atmospheric pressure), it is compressed and deposited on the upstream side of filter portion 85. On the other hand, heavy dust such as pebbles accumulates near the bottom of dust collection portion 110B. As the vacuum cleaner 1 continues to be used, even more light dust is compressed, and the dust deposits in a doughnut shape.

[0047] Then, the flow that flows into the inside of the inner tube 140 from the intake section 142 and the flow that flows from the inside of the umbrella section 144 toward the upper inner tube 141 merge together, pass through the dust trapping filter 132, and flow into the electric blower inlet 16 of the vacuum cleaner body 2 (see Figure 11).

[0048] As described above, the vacuum cleaner 1 of this embodiment includes the electric blower 5 and the first dust collecting unit 20 that stores dust collected by the suction force of the electric blower 5, and can be fitted with a second dust collecting unit 100 that has a different shape from the first dust collecting unit 20 in place of the first dust collecting unit 20. In this way, by providing the detachable first dust collecting unit 20 with, for example, a paper pack 50, it becomes possible to replace the paper pack 50 simply and hygienically.

[0049] In this embodiment, the first dust collecting unit 20 is a dust collecting unit to which the paper pack 50 can be attached, and the second dust collecting unit 100 is a cyclone type dust collecting unit. This allows the paper pack 50 to be attached, so it can be disposed of without swelling with dust, and because the first dust collecting unit 20 is detachable, it can be washed, which is also effective from a hygienic standpoint.

[0050] In this embodiment, the first dust collection unit 20 has an inlet 21b through which dust flows in and an opening 28 through which dust enters the paper pack 50. This makes it possible to collect dust in the paper pack 50 even if the first dust collection unit 20 is detachable.

[0051] In this embodiment, the inlet 21b is located to the right or left of the center of the lid 21 (side wall) of the first dust collecting unit 20, and the opening 28 is located approximately in the center of the lid 21. This allows a cyclone flow to be generated, and makes it possible to interchange the paper bag type first dust collecting unit 20 and the cyclone type second dust collecting unit 100.

[0052] The present invention is not limited to the above-described embodiment, and can be modified as appropriate within the scope of the present invention. For example, in the above-described embodiment, the paper bag-type first dust collecting unit 20 and the cyclone-type second dust collecting unit 100 are interchangeable, but both the first dust collecting unit and the second dust collecting unit may be paper bag-type, with one compatible with a regular paper bag and the other compatible with a smaller paper bag.
