Abstract
Description
[Technical field]
[0001] The present invention relates to a vacuum cleaner set and a stand for a vacuum cleaner. [Background technology]
[0002] Stick-type vacuum cleaners are electric vacuum cleaners that are used by a user to hold a handle attached to the main body of the vacuum cleaner. Stick-type vacuum cleaners are equipped with an electric blower and a dust collection unit inside the main body of the vacuum cleaner, and dust is sucked in from a suction body via an extension tube connected to the main body of the vacuum cleaner and collected in the dust collection unit.
[0003] In addition, a typical stick-type vacuum cleaner can also be used as a handheld vacuum cleaner by removing the extension tube connected to the main body of the vacuum cleaner and sucking in dust through the suction port of the main body of the vacuum cleaner.
[0004] Stick-type vacuum cleaners are generally stored by standing them up on a stand. The stand may have a structure for holding a charging plug so that the vacuum cleaner can be charged simply by standing it up. Such a vacuum cleaner is disclosed in, for example, Patent Document 1. [Prior art documents] [Patent documents]
[0005] [Patent Document 1] JP 2020-72837 A Summary of the Invention [Problem to be solved by the invention]
[0006] Vacuum cleaners that use dust filters in the dust collection section need to replace the dust filter when it becomes full of dust and the suction power decreases. This requires replacement dust filters to be prepared, and securing storage space for them has been an issue.
[0007] The stand for stick-type vacuum cleaners disclosed in Patent Document 1 is a stand for stick-type vacuum cleaners that can store a stick-type vacuum cleaner, has a structure for holding a charging plug, and allows the vacuum cleaner to be charged simply by leaning it against the wall.
[0008] However, the stick type vacuum cleaner of Patent Document 1 does not use a dust collection filter in the dust collection section, and therefore does not have a structure for ensuring a storage space for the dust collection filter.
[0009] An object of the present invention is to provide a vacuum cleaner stand which ensures a storage space for a dust collection filter and improves the ease of replacing the dust collection filter, and a vacuum cleaner set including the vacuum cleaner stand. [Means for solving the problem]
[0010] In order to achieve the above-mentioned object, the present invention provides a vacuum cleaner comprising a vacuum cleaner body and a stand capable of storing the vacuum cleaner body, the support stand having a base portion, a pillar extending upward from the base portion, and a holder portion connected to the upper part of the pillar, the holder portion having a dust collecting filter storage portion for storing a dust collecting filter. Effect of the Invention
[0011] According to the present invention, it is possible to provide a stand for a vacuum cleaner which improves the workability of replacing a dust collection filter. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0013] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In principle, the same elements are given the same reference numerals in all drawings. Furthermore, explanations of parts having the same functions will be omitted. Note that the configurations described below are merely examples, and it is not intended that the embodiment of the present invention is limited to the specific embodiments described below. EXAMPLES
[0014] FIG. 1 is an external perspective view of a vacuum cleaner according to a first embodiment of the present invention, showing the state where it is stored in a stand. FIG. 2 is an external perspective view of a vacuum cleaner according to a first embodiment of the present invention, showing the state where it is used as a stick type. FIG. 3 is an external perspective view of a vacuum cleaner according to a first embodiment of the present invention, showing the state where it is used as a handy type. FIG. 4 is a cross-sectional view of a vacuum cleaner body 10 of the vacuum cleaner 1 cut along the front-rear direction. In the first embodiment, front-rear, left-right, and up-down are defined from the viewpoint of a user performing cleaning, with the vacuum cleaner 1 as a reference, as shown by the arrows.
[0015] Stick-type vacuum cleaners are electric vacuum cleaners that are used by a user to hold a handle attached to the main body of the vacuum cleaner. Stick-type vacuum cleaners are equipped with an electric blower and a dust collection unit inside the main body of the vacuum cleaner, and dust is sucked in from a suction body via an extension tube connected to the main body of the vacuum cleaner and collected in the dust collection unit.
[0016] In addition, a typical stick-type vacuum cleaner can also be used as a handheld vacuum cleaner by removing the extension tube connected to the main body of the vacuum cleaner and sucking in dust through the suction port of the main body of the vacuum cleaner.
[0017] 1 and 2, the vacuum cleaner 1 includes a vacuum cleaner body 10 that forms an outer shell, an extension tube 20 having one end connected to the vacuum cleaner body 10 via a connection tube 101, and a suction body 30 connected to the other end of the extension tube 20. The suction body 30 incorporates a rotating cleaning body (not shown) and a motor that drives the rotating cleaning body, and is supplied with power from a storage battery through a lead wire arranged on the extension tube 20.
[0018] In addition, the electric vacuum cleaner 1 of the first embodiment is provided with a brush part 40 (omitted in FIG. 1) on the outer periphery of the connecting pipe 101. The connecting pipe 101 is fixed to the front of the vacuum cleaner body 10, and a suction passage 101a through which air flows is formed inside the connecting pipe 101, and the suction passage 101a communicates with the internal passage of the extension pipe 20.
[0019] The extension tube 20 is connected to the vacuum cleaner body 10 via a connecting tube 101. When not in use, the vacuum cleaner 1 is placed on a stand 50. The upper part of the connecting tube 101 is provided with a lock button 102a that prevents the extension tube 20 from coming loose when the extension tube 20 is connected, and a button cover 102 that covers the lock button 102a.
[0020] The vacuum cleaner body 10 has an outer shell made up of a lower case 10a, an upper case 10b arranged above the lower case 10a, and a dust-collecting section case 10c arranged in front of the lower case 10a. The lower case 10a is provided with a motor chamber 10f (electric blower housing) for housing the electric blower 14, and an exhaust port. The dust-collecting section case 10c is provided with a pack chamber 10e for housing the dust-collecting filter 120.
[0021] The vacuum cleaner body 10 also includes a dust collection section 12 that collects sucked-in dust, a dust collection lid 11 that opens and closes to cover the upper part of the dust collection section 12, and a handle section 13 that is held by the user when cleaning. The dust collection section 12 is formed by a dust collection section case 10c, and a pack chamber 10e is formed within this dust collection section 12.
[0022] The handle portion 13 is formed by a part of the upper case 10b.
[0023] The dust collection lid 11 opens and closes around a rotating shaft 105, and is biased in a direction to open the dust collection lid 11 by a coil spring 110 (FIG. 8) described later. The dust collection lid 11 also holds the dust collection section 12 in a closed state by a dust collection lid clamp 112. The lower case 10a forming the lower side of the dust collection section 12 is provided with a dust collection section gasket 127 (FIG. 8), and when the dust collection lid 11 is closed, the dust collection lid 11 comes into contact with the dust collection section gasket 127 to keep the inside of the dust collection section 12 airtight.
[0024] By forming the dust collection cover 11 from a translucent material, the bulge of the dust collection filter 120 can be confirmed, and the design can be further improved.
[0025] A rib 10d is formed on the button cover 102 near the rear of the dust collection lid claw 11a that hooks onto the dust collection lid clamp 112. With this, when a user lifts the vacuum cleaner 1 by holding the handle portion 13 in use as a stick type, the dust collection lid claw 11a is pressed down by the rib 10d, so that the entire vacuum cleaner body 10 is warped, preventing the dust collection lid claw 11a from coming off the dust collection lid clamp 112.
[0026] Inside the vacuum cleaner body 10 are an electric blower 14 (Figure 4) that generates suction force, a control board 15 (Figure 4) that mounts a control device that controls the electric blower 14, and a battery pack 16 that is located behind the electric blower 14 and has multiple storage batteries that supply power to the electric blower 14.
[0027] The battery pack 16 is fixed by a battery clamp 114, and by pressing the battery attachment / detachment button 113, the battery clamp 114 moves in conjunction with the battery pack 16, releasing the fixed part of the battery pack 16 and allowing the battery pack 16 to be removed. This allows the user to operate the device for a long time by replacing multiple battery packs 16 if the user owns multiple battery packs 16. In addition, when the battery pack 16 reaches the end of its life, the user can easily replace it with a new battery pack 16.
[0028] An operation switch 17 is disposed on the handle portion 13 for turning the electric blower 14 on and off and for adjusting the suction power.
[0029] 4, dust collecting section 12 is detachably provided with disposable dust collecting filter 120 that collects and filters dust sucked from suction passage 101a. Dust collecting filter 120 is composed of a bag member 121 that is breathable and flexible and collects dust, and a support plate 122 having an inlet 122a formed in the center. Support plate 122 is inserted along a guide groove described later, and an upper portion is fixed to dust collecting section 12 by support plate clamp (support plate fixing section) 104.
[0030] The dust collecting filter 120 is attached to the dust collecting unit 12 by fixing the support plate 122 with the support plate clamp 104 .
[0031] With the central axis of suction passage 101a (central axis A of suction port 101b) horizontal, support plate 122 is inclined so that its upper portion is located further rearward than its lower portion when attached to dust collection section 12. In other words, central axis A of suction port 101b and central axis E of dust collection filter 120 and support plate 122 are not parallel, but are inclined by approximately 20° (different angles).
[0032] Between the connection pipe 101 and the dust collecting section 12, there are provided a port packing 103 which forms an inflow passage 103a, and a holding member 1030 which is arranged on the outer periphery of the port packing 103 and holds the port packing 103.
[0033] The port packing 103 is formed with an inlet passage 103a (center axis C) that connects the suction passage 101a of the connecting pipe 101 to the dust collecting unit 12, and a rear lip 103c (center axis E) that abuts against the support plate 122. The port packing 103 connects the suction passage 101a of the connecting pipe 101 to the dust collecting unit 12.
[0034] In addition, the mouth packing 103 is formed of a flexible material. For example, SBR is used as the flexible material, and a mating surface between a mold on the inflow passage 103a side and a mold on the rear lip 103c side is provided on the side of the check valve 103d, whereby a thin plate portion can be generated on the side of the check valve 103d, and the thin plate portion can serve as a thread rib to reduce the gap between the check valve 103d and the inflow passage 103a. By reducing the gap between the check valve 103d and the inflow passage 103a, dust accumulated in the dust collection filter 120 can be prevented from flowing back to the inflow passage 103a side. A lip-shaped rear lip 103c is provided at the rear end of the mouth packing 103, and airtightness is maintained by abutting against the support plate 122.
[0035] When airtightness is maintained at the inlet 122a, the mouth packing 103 does not need to be used. For example, airtightness can be maintained with an airtightness maintaining mechanism 1032 (FIG. 24) composed of a holding member 1030 and an elastic member 1031 connected to the front side (connecting pipe 101 side) of the holding member 1030. By fixing an end of the elastic member to the connecting pipe 101, the holding member 1030 connected to the elastic member can be pressed against the support plate 122 by the elastic force of the elastic member 1031. As a result, the rear side (guide member side) end of the holding member 1030 comes into contact with the support plate 122, maintaining airtightness.
[0036] Furthermore, a groove in the shape of the end of the holding member 1030 can be formed in the support plate 122. With this, the end of the holding member 1030 fits into the groove, blocking the escape route of air and further improving airtightness.
[0037] Dust sucked in from the suction port 101b of the suction passage 101a passes through the suction passage 101a and the inlet passage 103a of the mouth packing 103 together with air, and is collected in the bag member 121 of the dust collection filter 120 from the inlet port 122a of the support plate 122. The dust sucked into the bag member 121 is filtered by the bag member 121, and the air passing through the bag member 121 passes through the protective filter 180 and the electric blower opening 12b and is sucked into the electric blower 14. The protective filter 180 is disposed between the dust collection filter 120 and the electric blower opening 12b to prevent dust leaking from the bag member 121 from being sucked into the electric blower 14. The protective filter 180 is supported by a filter frame 18 that is slidable in the approximately vertical direction, and is attached to the dust collection unit 12.
[0038] Electric blower 14 includes fan 141 that generates suction force, and electric motor 143 that is connected to fan 141 via rotating shaft 142 and drives fan 141 to rotate. Rotation center line D of rotating shaft 142 of electric blower 14 is disposed at an angle that descends toward the downstream side (rear side).
[0039] A battery pack 16 that supplies power to the electric blower 14 is provided on the downstream side (rear side) of the electric blower 14.
[0040] When used as a stick-type vacuum cleaner, the suction body 30 is connected to the connection tube 101 of the vacuum cleaner body 10 via the extension tube 20 as shown in Fig. 2. The user grips the handle 13 and operates the operation switch 17 to drive the electric blower 14 and move the suction body 30 back and forth. The suction force of the electric blower 14 generates suction force in the suction body 30. Dust sucked through the suction body 30 passes through the extension tube 20 and is collected in the dust collection filter 120 of the dust collection section 12.
[0041] When using the vacuum cleaner as a handheld type electric vacuum cleaner, the extension tube 20 is removed from the connecting tube 101 of the vacuum cleaner body 10 as shown in Fig. 3. By removing the extension tube 20 from the connecting tube 101, the suction port 101b of the suction passage 101a is exposed. The user grips the handle portion 13 and operates the operation switch 17 to drive the electric blower 14 and move the connecting tube 101. Then, dust is directly sucked in through the suction port 101b, and the sucked in dust is collected in the dust collection filter 120 of the dust collection unit 12.
[0042] In a typical vacuum cleaner, support plate 122 is perpendicular to central axis A of suction port 101b, and so in this state bag member 121 can be sufficiently inflated to ensure dust collection capacity, and the top surface of the vacuum cleaner body is formed to gradually inflate upward from the suction port of the vacuum cleaner body toward the rear of the vacuum cleaner body, but when used as a handheld vacuum cleaner, there is a problem that the suction port is not visible and it is difficult to clean dust on the floor. A configuration for solving this problem will be described with reference to FIG.
[0043] In Fig. 4, when the central axis of the suction port 101b is A and the central position of the inlet of the dust collection filter 120 (the central position of the inlet 122a of the support plate 122) is B, in the first embodiment, the central axis A of the suction port 101b is positioned above the central position B of the inlet of the dust collection filter 120 (the central position of the inlet 122a of the support plate 122). In other words, the central axis A of the suction port 101b is positioned closer to the handle part 13 than the central position B of the inlet of the dust collection filter 120 (the central position of the inlet 122a of the support plate 122). In addition, the central axis E of the dust collection filter 120 (the central axis of the inlet 122a of the support plate 122) is inclined downward toward the downstream side with respect to the central axis A of the suction port 101b.
[0044] A gasket 103 is formed between the downstream side (rear side) of the suction passage 101a and the inlet 122a of the dust collecting filter 120, and is inclined downward toward the downstream side (rear side), so that the center position B of the inlet of the dust collecting filter 120 is located below the central axis A of the suction port 101b.
[0045] According to the first embodiment, the central axis A of the suction port 101b is positioned above the central position B of the inlet of the dust collection filter 120 (the central position of the inlet 122a of the support plate 122). Therefore, when used as a handheld vacuum cleaner, the suction port 101b is easily visible from the user's line of sight, improving operability during cleaning.
[0046] Furthermore, according to the first embodiment, the upper surface of the suction port 101b is formed linearly toward the handle portion 13 side (rear side) without any unevenness, thereby improving the design.
[0047] Furthermore, according to the first embodiment, the central axis A of the suction port 101b and the central position B of the inlet of the dust collecting filter 120 are positioned so as to be offset from each other. Therefore, when the vacuum cleaner body 10 is stood upright with the suction port 101b facing downwards, the dust collected in the dust collecting filter 120 can be prevented from spilling out from the inlet 122a and being discharged to the outside from the suction port 101b.
[0048] Furthermore, in the first embodiment, when the central axis of dust collecting filter 120 is E, central axis A of suction port 101b and central axis E of dust collecting filter 120 are configured not to be parallel to each other. With this configuration, when dust collecting filter 120 is removed from dust collecting section 12, dust collected in dust collecting filter 120 spills out from inlet 122a, and the spilled dust can be prevented from being discharged to the outside from suction port 101b.
[0049] In the first embodiment, the user grips the handle portion 13 to operate the vacuum cleaner 1, so a moment is applied to the user's hand. For this reason, in the vacuum cleaner 1, it is preferable to reduce the moment applied to the hand when the user grips the handle portion 13 to operate the vacuum cleaner 1. Therefore, in the first embodiment, the handle portion 13 is configured to straddle the extension line of the central axis A of the suction port 101b. In other words, the handle portion 13 in the first embodiment is configured to intersect with the extension line of the central axis A of the suction port 101b. By configuring as described above in the first embodiment, the moment applied to the user's hand can be reduced, and the operability of the vacuum cleaner can be improved.
[0050] In the electric vacuum cleaner 1, it is preferable to reduce the ventilation loss in order to improve the dust collection efficiency. Therefore, in the first embodiment, when the rotation center line of the rotation shaft 142 of the electric blower 14 is D, the rotation center line D of the rotation shaft 142 of the electric blower 14 and the central axis E of the dust collection filter 120 are configured to be parallel. By configuring in this way, the ventilation loss from the dust collection filter 120 to the electric blower 14 can be reduced, and the dust collection efficiency can be improved. To further improve the efficiency, the rotation center line D of the electric blower and the central axis E of the dust collection filter 120 may be on a straight line. In particular, in an electric vacuum cleaner equipped with a storage battery, the operating time of the electric blower 14 can be reduced by improving the dust collection efficiency, and the weight of the electric vacuum cleaner can be reduced by miniaturizing the storage battery.
[0051] The central axis C of the inlet passage 103a of the port packing is inclined downward toward the downstream side with respect to the central axis A of the suction port 101b of the connecting pipe 101.
[0052] In addition, in the electric vacuum cleaner 1, it is desirable to enlarge the dust collection section 12 in order to ensure the amount of dust collection. However, in order to suppress the deterioration of operability, it is preferable not to enlarge the vacuum cleaner body 10 more than necessary. Therefore, in the first embodiment, the central axis C of the inlet passage 103a of the mouth packing is configured to be tilted further rearward than the central axis E of the support plate 122 of the dust collection filter 120 (approximately 25° with respect to the central axis A). In other words, the central axis C of the inlet passage 103a and the central axis E of the support plate 122 of the dust collection filter 120 are set at different angles. With this configuration, the length of the inlet passage 103a in the front-rear direction can be suppressed while ensuring the area of the support plate 122, so that the dust collection section 12 can be enlarged while suppressing the length of the vacuum cleaner body 10.
[0053] In addition, it is desirable that the electric vacuum cleaner 1 is small. The battery pack 16 stored in the vacuum cleaner body 10 has a larger volume than the electric blower 14 in order to secure the battery capacity, which is a cause of the vacuum cleaner body 10 becoming large. Therefore, in the first embodiment, when the central axis of the battery pack 16 is G, the central axis G of the battery pack 16 is positioned above the rotation center line D of the rotation shaft 142 of the electric blower 14. By configuring in this way, it is possible to prevent the part of the vacuum cleaner body 10 that stores the battery pack 16 from expanding, and it is possible to prevent the vacuum cleaner body 10 from becoming large. Furthermore, in the first embodiment, when the parallel line of the control board 15 is F, the parallel line F of the control board 15 is not parallel to the rotation center line D of the rotation shaft 142 of the electric blower 14. As described above, the battery pack 16 has a larger volume than the electric blower 14, so in the first embodiment, the control board 15 is arranged in consideration of the volumes of the electric blower 14 and the battery pack 16. This makes it possible to prevent the vacuum cleaner 1 from becoming large.
[0054] It is also desirable for the vacuum cleaner 1 to be lightweight. The weight can be reduced by providing projections and recesses on the inside of the lower case 10a and upper case 10b that form the outer shell so that the thickness of the outer shell varies (using topology weight reduction technology). It is desirable for the projections and recesses to be thick in areas where strength is required and thin in areas where it is not, and the shape may be determined by simulation.
[0055] In FIG. 4, point P1 indicates the center of gravity in the handheld state, and point P2 indicates the center of gravity in the stick state.
[0056] According to the first embodiment, the central axis E of the support plate 122 is inclined in the range of 5° to 76.5° so that the upper part of the support plate 122 is located further rearward than the lower part when the central axis A of the suction port 101b is horizontal. This makes it easier for the guide member 128 and the dust collection filter 120 to rotate toward the removal position due to their own weight when the support plate clamp 104 is opened, and dust is less likely to spill out because the inlet 122a faces upward toward the main body. Furthermore, it is preferable that the inclination is in the range of 10° to 40°. In this embodiment, the inclination is set to approximately 20°.
[0057] Next, the configurations of the dust collecting filter 120 and the dust collecting section 12 will be described with reference to Fig. 5 and Fig. 6. Fig. 5 is an external perspective view of the dust collecting filter 120 according to the first embodiment of the present invention in a folded state. Fig. 6 is an external perspective view of the dust collecting filter 120 according to the first embodiment of the present invention when being disposed of.
[0058] The dust collecting filter 120 includes a quadrilateral support plate 122 having an inlet 122a and made of cardboard, plastic, or the like, a breathable bag member 121 made of paper, cloth, nonwoven fabric such as animal hair, plastic, or the like, and a seal member 123 attached to the support plate 122. The bag member 121 is adhered to the back surface side of the support plate 122. In the second embodiment, the seal member 123 is attached to one of the quadrilateral support plate 122. Although the seal member 123 is attached to the support plate 122 in the second embodiment, it may be attached by adhering to a part of the bag member 121.
[0059] The bonded portion between the bag member 121 and the support plate 122 does not extend over the entire support plate 122, and the outer periphery of the support plate 122 is not bonded to the bag member 121. The bag member 121 is bonded around the opening of the support plate 122. When the support plate 122 is attached to the dust collecting unit 12 of the vacuum cleaner 1, it is caught and fixed by the claws of the support plate clamp 104. However, if the bag member 121 is bonded up to the outer periphery of the support plate 122, the support plate 122 cannot be caught by the claws of the support plate clamp 104, and there is a risk that the claws of the support plate clamp 104 may damage the bag member 121. For this reason, in the second embodiment, the outer periphery of the support plate 122 is not bonded to the bag member 121. The portion where the support plate 122 and the bag member 121 are not bonded must be at least one side of the support plate 122, i.e., the side that is hooked onto the claw portion of the support plate clamp 104, but the other sides may be bonded up to the end of the support plate 122.
[0060] The sealing member 123 is attached to the back surface side of the support plate 122 in a portion where the support plate 122 and the bag member 121 are not bonded. In the second embodiment, the sealing member 123 is attached to the upper side of the back surface of the support plate 122. When bonding the sealing member 123 to the upper side of the back surface of the support plate 122, it is preferable not to bond the vicinity of the end of the support plate 122. The reason for this is that the upper side of the support plate 122 is caught and fixed by the claw portion of the support plate clamp 104, so in order to avoid damaging the sealing member 123, it is preferable not to bond the support plate 122 and the sealing member 123 to the portion that is caught by the claw portion of the support plate clamp 104.
[0061] The seal member 123 includes a seal portion 124 having a glue as an adhesive surface, and a release paper 125 (release portion) covering the adhesive surface. The seal portion 124 and the release paper 125 are arranged such that the release paper 125 is located on the front side of the support plate 122 and the seal portion 124 is located on the back side of the support plate 122, with the glue as a boundary. The release paper 125 is formed with a hook hole 126 for hooking onto a protrusion 104a provided on the support plate clamp 104 of the vacuum cleaner 1. The release paper 125 may be fixed to a component other than the support plate 122. Furthermore, the fixing method may be such that an adhesive portion is provided on the release paper 125 and the release paper 125 is attached to the fixed component, or a mechanism is provided for sandwiching the release paper 125 between the fixed components. By providing a seal member fixing portion for fixing the release paper 125, a part of the seal member 123 that seals the opening of the support plate 122 can be fixed, and the opening can be sealed when replacing the dust collection filter.
[0062] When release paper 125 of sealing member 123 is peeled off from below (the hook hole 126 side), the adhesive surface of sealing portion 124 is exposed. Then, sealing portion 124 is folded back over the upper part of support plate 122, the exposed adhesive surface faces the front surface of support plate 122, and the adhesive surface of sealing portion 124 is affixed to support plate 122. Inflow port 122a of support plate 122 is covered and blocked by sealing portion 124, so that spilling of dust from inflow port 122a can be suppressed even when dust collection filter 120 is disposed of, and the dust collection filter 120 can be handled hygienically.
[0063] It is preferable that the sealing portion 124 closes the inlet 122a of the support plate 122 when the dust collecting filter 120 is removed from the dust collecting part 12 of the vacuum cleaner 1. The removal operation of the dust collecting filter 120 will be described with reference to Figs. 7 to 11.
[0064] FIG. 7 is a diagram showing a state in which the dust collecting filter 120 is removed from the dust collecting unit 12 of the vacuum cleaner 1 according to the first embodiment of the present invention. FIG. 8 is an enlarged view of the main part of FIG. 7 showing the opening operation function of the dust collecting lid 11 and the structure of the guide member 128. FIG. 9 is an exploded perspective view of the vacuum cleaner 1 according to the first embodiment of the present invention in a state in which the filter frame 18 and the protective filter 180 are removed. FIG. 10 is a perspective view of the vacuum cleaner 1 according to the first embodiment of the present invention as seen from the rear side. FIG. 11 is a side view showing the operation of the filter frame 18 when the dust collecting filter 120 with the bag member 121 inflated is pulled out, where (A) shows a state before the dust collecting filter 120 is pulled out and (B) shows a state after the dust collecting filter 120 is pulled out.
[0065] The dust collecting section 12 is provided with a guide member 128 that guides the support plate 122 of the dust collecting filter 120. The guide member 128 is formed in a U-shape when viewed from the front. The guide member 128 is provided with an insertion portion 128a into which the support plate 122 of the dust collecting filter 120 is inserted, and a guide groove 128b that guides the support plate 122 inserted from the insertion portion 128a downward. The insertion portion 128a is formed to widen upward so that the support plate 122 can be easily inserted. A rotating shaft 128c that rotatably supports the guide member 128 is provided on both the left and right sides below the guide member 128. When the angle between the mounting position and the removal position of the guide member 128 is in the range of 5° to 25°, the dust collecting filter 120 can be removed. Furthermore, if the angle is in the range of 10° to 20°, the operability of the dust collection filter 120 is improved, and dust is less likely to spill out during a series of operations for replacing the dust collection filter 120. In this embodiment, the angle is set to 13.5°.
[0066] Furthermore, when the guide member 128 is in the removal position, if the shortest distance between the fixing portion of the release paper 125 and the filter support plate is 0 mm or more and 20.0 mm or less, the dust collecting filter 120 can be removed. Furthermore, if the shortest distance is 2.8 mm or more and 14.6 mm or less, the operability of the dust collecting filter is improved and dust is less likely to spill during the series of operations for replacing the dust collecting filter. In this embodiment, it is 7.1 mm.
[0067] When the dust collection filter 120 is attached to the dust collection unit 12 of the vacuum cleaner 1, the dust collection lid 11 is opened, and the support plate 122 of the folded dust collection filter 120 (FIG. 5) is inserted along the insertion portion 128a and the guide groove 128b of the guide member 128, and is made to face the outlet portion of the mouth packing 103. Then, the guide member 128 is rotated forward, and the upper portion of the support plate 122 is hooked onto the claw portion of the support plate clamp 104 and fixed. Also, the hook hole 126 formed in the release paper 125 is hooked onto the protrusion portion 104a of the support plate clamp 104. Then, the dust collection lid 11 is closed.
[0068] The dust collection lid 11 is biased in an opening direction by a coil spring 110 as shown in FIG. 8. Two coil springs 110 are arranged side by side in the left-right direction. One lower end 110a of the coil spring 110 is hooked on the fixed part 106 of the vacuum cleaner body 10, and the other upper end 110b is in contact with the dust collection lid 11. With this configuration, the dust collection lid 11 is biased in an opening direction. In addition, the upper end 110b of the coil spring 110 on the dust collection lid 11 side is bent toward the dust collection part 12 side. With this, during manufacturing and assembly, after the coil spring 110 is attached to the fixed part 106, the bent part acts as a guide when attaching the dust collection lid 11 while holding down the end of the coil spring, making it easy to attach.
[0069] Further, the rotation shaft 128c of the guide member 128 is provided rotatably at the position of the front inner wall 12d of the dust collecting unit 12. The front inner wall 12d of the dust collecting unit 12 is inclined downward from the front to the rear with respect to the central axis A (see FIG. 4) of the suction port 101b. In this embodiment, the rotation shaft 128c is disposed on the inclined front inner wall 12d.
[0070] For example, when replacing the dust collection filter 120, dust may spill from the inlet 122a of the support plate 122, fall downward, and accumulate near the rotating shaft 128c. If dust accumulates near the rotating shaft 128c, the guide member 128 becomes difficult to rotate. Therefore, in this embodiment, the rotating shaft 128c is disposed on the inclined front inner wall 12d. In this embodiment, dust that spills from the inlet 122a and falls downward does not remain on the rotating shaft 128c, but moves below the rotating shaft 128c along the inclined front inner wall 12d, so that the rotating operation of the guide member 128 can be stabilized.
[0071] The inner wall 12a of the dust collecting section 12, which is separated from the electric blower 14, is formed with a communication opening 151 that communicates with the space in which the control board 15 is housed. In the vacuum cleaner 1, the control software written in the control board 15 may be rewritten for maintenance or to improve malfunctions. In this embodiment, a tool can be inserted through the communication opening 151 to rewrite the control software. The communication opening 151 is arranged outside the dust collecting section packing 127, so that it is not related to the airtight structure of the dust collecting section 12. During normal use, the communication opening 151 needs to be closed so that the user does not touch the control board 15. Therefore, in this embodiment, a label 152 is attached so as to close the communication opening 151. The model of the dust collecting filter 120 attached to the dust collecting section 12 is written on the label 152. The user can purchase a replacement dust collecting filter 120 by looking at the model written on the label 152. In addition, since the user can easily confirm the model, it is possible to prevent a dust collecting filter 120 of a different model from being mistakenly attached. The affixed surface of the label 152 is inclined with respect to a line perpendicular to the rotation center line D of the rotation shaft 142 of the electric blower 14 so that the upper side is rearward relative to the lower side (see FIG. 4). This makes it easy for the user to see the model written on the label 152. Similarly, the affixed surface of the label 152 is inclined with respect to a line perpendicular to the parallel line F of the control board 15 so that the upper side is rearward relative to the lower side (see FIG. 4). This makes it easy to grasp the position of the control software rewriting connector (not shown) on the control board 15, improving workability. Therefore, the affixed surface of the label 152 is not perpendicular to the rotation center line D of the rotation shaft 142 of the electric blower 14 and the parallel line F of the control board 15.
[0072] Moreover, an opening 12b for the electric blower is formed in the inner wall 12a of the dust collecting section 12, and the opening 12b for the electric blower is located in front of the electric blower 14. The opening 12b for the electric blower has a lattice shape to prevent a user from accidentally putting his / her fingers into the electric blower 14 while ensuring an air inflow path.
[0073] When the electric blower 14 is driven and a suction force is generated, the bag member 121 of the dust collection filter 120 expands due to the suction airflow, and dust is collected in the bag member 121. The downstream side of the bag member 121 is held by the filter frame 18. As shown in FIG. 9, the filter frame 18 has a lattice portion 18a having a large opening in the front-rear direction, and the protective filter 180 is supported in contact with the front surface of the lattice portion 18a. As a result, even if the bag member 121 expands, it abuts against the lattice portion 18a in a manner sandwiching the protective filter 180, so that the bag member 121 and the protective filter 180 are prevented from directly blocking the inlet portion of the electric blower 14, and the suction force can be easily maintained. The filter frame 18 also has an upper surface opening 18b and a side surface opening 18c. As a result, even if the lattice portion 18a having an opening in the front-rear direction is blocked by the bag member 121, the suction force can be easily maintained by sucking in air from the surrounding openings.
[0074] In addition, dust collection lid 11 and dust collection case 10c are each provided with ribs or convex shapes from the front to the rear of vacuum cleaner 1. As a result, even if bag member 121 expands, bag member 121 abuts against the convex shapes and does not expand any further, preventing the bag member from sticking to dust collection lid 11 and dust collection case 10c and blocking the flow path, and making it difficult for the suction power to decrease. In other words, by forming a concave shape that becomes the flow path using ribs and convex shapes in dust collection part 11 and dust collection case 10c, it is possible to easily maintain the suction power even when bag member 121 expands.
[0075] When the electric blower 14 is driven and suction force is generated, the dust collection lid 11 is bent inward due to negative pressure. The inside of the dust collection lid 11 is provided with a contact portion 111 that comes into contact with the dust collection case 10c of the vacuum cleaner body 10 when the dust collection lid 11 is bent. When the electric blower 14 is driven, the contact portion 111 comes into contact with the dust collection case 10c, thereby preventing the dust collection lid 11 from opening.
[0076] When the bag member 121 becomes full of dust and the dust collection filter 120 needs to be replaced, the dust collection lid 11 is rotated open, the support plate 122 hooked on the claw portion of the support plate clamp 104 is shifted from the position of the claw portion, and the dust collection filter 120 is pulled upward (FIG. 7).
[0077] The bag member 121 swells and sticks to the inner wall of the dust collecting section 12, particularly to the filter frame 18 on the electric blower 14 side. In the configuration of the second embodiment, the filter frame 18 can slide in a substantially vertical direction as shown in Figs. 11(A) and 11(B). When the dust collecting filter 120 is pulled out upward, the filter frame 18 also slides upward, and the dust collecting filter 120 can be easily pulled up. Furthermore, in this embodiment, a raised shape 18d is provided on the upper part of the filter frame 18 (Fig. 9). As a result, when the bag member 121 swells to the extent that it sticks to the filter frame 18, the bag member 121 slips under the raised shape 18d, so that when the dust collecting filter 120 is pulled out, the raised shape 18d is pushed upward, and the filter frame 18 can slide easily (Figs. 11(A) and (B)).
[0078] The filter frame 18 is provided with a protrusion 18e, and the inner wall 12a of the dust collecting unit 12 on the electric blower 14 side is provided with a recess 12c, which is a groove of a substantially rectangular shape (FIG. 9). The recess 12c is larger in the vertical direction than the protrusion 18e, and the filter frame 18 is provided on the dust collecting unit 12 in such a manner that the protrusion 18e fits into the recess 12c. This allows the filter frame 18 to slide in the vertical direction, and when the filter frame 18 is pulled out, the protrusion 18e hits the upper end surface of the recess 12c to prevent it from coming off. The position of the recess 12c does not overlap with the electric blower opening 12b in the horizontal direction. This makes it difficult for the size of the recess 12c in the vertical direction, and therefore the sliding range of the filter frame 18, to be affected by the size of the electric blower opening 12b. In this embodiment, the recess 12c is provided on the electric blower 14 side of the inner wall 12a, but it may be provided on the side of the inner wall 12a. For example, if the left-right size of opening 12b for the electric blower occupies most of inner wall 12a on the electric blower 14 side, the space available for providing recess 12c in inner wall 12a on the electric blower 14 side will be limited; however, this problem can be avoided by providing recess 12c in inner wall 12a on the side surface.
[0079] In addition, because the hook hole 126 formed in the release paper 125 is hooked on the protrusion 104a of the support plate clamp 104, when the dust collection filter 120 is pulled upward, the release paper 125 is rolled up from the seal portion 124, and the seal portion 124 is further pulled and folded back toward the front surface of the support plate 122, so that the seal portion 124 adheres to the surface of the support plate 122 and closes the inlet 122a. This makes it possible to prevent dust from spilling out from the inlet 122a.
[0080] The dust collection filter 120 in this embodiment is a disposable dust collection filter that is replaced when it becomes full of dust. For this reason, it is necessary to prepare replacement dust collection filters, but there is a risk that the purchase of a new one may be forgotten. Therefore, a sensor that detects that the dust collection filter 120 has been replaced may be provided in the vacuum cleaner 1, and a dust collection filter 120 may be automatically ordered according to the number of times the dust collection filter 120 has been replaced. For example, a home server may be installed, and the home server may be wirelessly connected to the vacuum cleaner 1, and the home server may receive information from the vacuum cleaner 1 that the dust collection filter 120 has been replaced, and place an order with the store.
[0081] The configuration of the dust collecting section 12 will be described with reference to Figs. 12 to 16. Fig. 12 is an exploded perspective view of the vacuum cleaner 1 with the dust collecting section 12 disassembled according to the first embodiment of the present invention. Fig. 13 is an exploded perspective view of a state in which the button cover 102 is removed from the connecting pipe 101 according to the first embodiment of the present invention. Fig. 14 is a perspective view of a state in which the button cover 102 is attached to the connecting pipe 101 from the state shown in Fig. 13. Fig. 15 is a perspective view of the port packing 103 according to the first embodiment of the present invention as seen from the front. Fig. 16 is a perspective view of the port packing 103 according to the first embodiment of the present invention as seen from the rear.
[0082] An extension pipe 20 is connected to a connection pipe 101 located at the front of the vacuum cleaner body 10. During cleaning in an electric vacuum cleaner, the reaction force from the surface to be cleaned is transmitted to the connecting tube 101 via the suction body 30 and the extension tube 20, so it is necessary to ensure the strength between the vacuum cleaner body 10 and the connecting tube 101.
[0083] To solve this problem, in this embodiment, the connecting pipe 101 located at the front of the vacuum cleaner body 10 is formed integrally with the dust collection section case 10c that forms the dust collection section 12, thereby ensuring strength between the vacuum cleaner body 10 and the connecting pipe 101.
[0084] In addition, in the vacuum cleaner 1 of this embodiment, the central axis C (see FIG. 4) of the inflow passage 103a is inclined downward from the front to the rear, so it is difficult to integrally form the inflow passage 103a connecting the connecting pipe 101 and the dust collecting unit 12 as the dust collecting unit case 10c. Therefore, in this embodiment, a holding member 1030 that forms the inflow passage 103a is provided. Then, a port packing 103 is inserted inside the holding member 1030. The port packing 103 covered by the holding member 1030 is attached from the inside of the dust collecting unit 12.
[0085] An end of the connecting pipe 101 comes into contact with a front lip 103b of the port packing 103. Since the port packing 103 is made of a flexible material, when the front lip 103b comes into contact with the connecting pipe 101, airtightness can be ensured between the suction passage 101a and the inlet passage 103a.
[0086] A cosmetic cover 10g is provided on the front side of the dust collection unit case 10c so as to cover the front side of the dust collection unit case 10c. A cutout portion 101c is formed at the position where the holding member 1030 of the dust collection unit case 10c is provided, and a part of the holding member 1030 is exposed from the cutout portion 101c. A fixing protrusion 10g1 is formed on the inner surface (upper side) of the cosmetic cover 10g. When the cosmetic cover 10g is attached to the front side of the dust collection unit case 10c, the fixing protrusion 10g1 is inserted into the cutout portion 101c, and the fixing protrusion 10g1 contacts and presses the holding member 1030, so that the holding member 1030 is fixed between the connection pipe 101 and the dust collection unit 12. In addition, a lead wire (not shown) for supplying power to the suction body 30 is arranged on the front side of the dust collection unit case 10c, and the lead wire is covered by the cosmetic cover 10g.
[0087] A dust collection section gasket 127 is disposed on the upper opening edge of the dust collection section case 10c to come into contact with the dust collection lid 11 when the dust collection lid 11 is closed to keep the dust collection section 12 airtight. The front of the dust collection section gasket 127 is disposed between the support plate clamp 104 and the dust collection lid clamp 112, and the rear of the dust collection section gasket 127 is disposed behind the filter frame 18. A gasket fixing portion 127a is formed on the front end of the dust collection section gasket 127 (FIGS. 12 and 13).
[0088] Button cover 102 is disposed above connecting pipe 101, covering the lock button 102a and the upper part of dust collection lid clamp 112. When dust collection lid clamp 112 is disposed above connecting pipe 101, dust collection lid clamp 112 covers packing fixing part 127a at the front end part of dust collection part packing 127. As a result, packing fixing part 127a is sandwiched from above and below by dust collection part case 10c and button cover 102, and the front part of dust collection part packing 127 is fixed to dust collection part case 10c (FIG. 14).
[0089] In this embodiment, the dust collection lid 11 has a claw portion facing forward and is hooked by the dust collection lid clamp 112, but the dust collection lid 11 may have a claw portion facing backward and a claw receiving portion provided on the button cover 102 for hooking, so that the user can directly place their hand on the dust collection lid 11 to open it. In that case, the dust collection lid clamp 112 can be omitted.
[0090] A lead wire (not shown) for supplying power to the suction port is wired between the dust collection unit packing 127 and the dust collection unit case 10c. Since the dust collection unit packing 127 is attached to the dust collection unit case 10c side, the lead wire is not visible to the user, ensuring a good design.
[0091] In addition, the dust collection unit packing 127 has a shape in which the left and right sides are lowered and the front and rear sides are raised. This ensures the paths of the front inlet and the rear motor inlet, while the left and right sides are lowered, widening the range of the dust collection lid 11, making it easier for the user to approach the dust collection unit 12 when the dust collection lid 11 is opened, and facilitating replacement of the dust collection filter 120.
[0092] As shown in Figures 15 and 16, the mouth gasket 103 is provided with a front lip 103b that contacts the end of the connecting pipe 101, a rear lip 103c that is larger in diameter than the front lip 103b and that contacts the support plate 122 of the dust collecting filter 120, a check valve 103d that prevents dust collected in the bag member 121 of the dust collecting filter 120 from leaking out, and a check valve connection portion 103e that connects the check valve 103d and the rear lip 103c.
[0093] Since the mouth packing 103 is formed of a flexible material, when the rear lip 103c comes into contact with the support plate 122, airtightness can be ensured between the inflow passage 103a and the inflow port 122a.
[0094] The check valve 103d operates to open downstream (rearward) with the check valve connection part 103e as a fulcrum. By making the check valve connection part 103e convex toward the rear lip 103c and concave toward the front lip 103b with respect to the check valve 103d, it is easier to operate toward the rear lip 103c than when the check valve connection part 103e and the check valve 103d are on the same surface. In addition, a pair of intra-passage protrusions 103f protruding toward the side where the inflow passage 103a is not provided is provided on the left and right in the inflow passage 103a of the mouth packing 103. Furthermore, the intra-passage protrusions 103f are also provided at diagonal positions with respect to the check valve connection part 103e in the inflow passage 103a. The intra-passage protrusions 103f suppress the check valve 103d from opening upstream (front). This makes it possible to suppress the leakage of dust collected in the bag member 121 of the dust collection filter 120. A check valve rib 103g is provided on the front lip 103b side of the check valve 103d to ensure the rigidity of the check valve 103d, thereby suppressing noise caused by the vibration of the check valve 103d. Furthermore, by arranging a passage protrusion 103f at the position where the check valve rib 103g is arranged, it is possible to prevent the check valve 103d from bending toward the front lip 103b due to the weight of dust. The passage protrusion 103f is bent toward the front lip 103b at an L angle, so that when the port packing 103 is pulled toward the rear lip 103c, the port packing 103 gets caught by the passage protrusion 103f, making it difficult for the port packing 103 to come off. The end face of the passage protrusion 103f on the front lip 103b side is chamfered, which reduces flow path loss during suction and reduces the amount of suctioned dust getting caught by the passage protrusion 103f. The rear lip 103c includes an outer lip 103j and an inner lip 103i. When the dust collection filter 120 is attached, each lip flexes to ensure airtightness between the mouth packing 103 and the support plate 122. By making the inner diameter of the tip of the inner lip 103i when the dust collection filter 120 is attached smaller than the outer diameter of the inlet 122a of the dust collection filter 120, it is possible to reduce flow path loss and dust catching at the support plate 122. The mouth packing 103 includes a spill prevention rib 103h on the inside of the inner lip 103i.By making the outside diameter of the spill prevention rib 103h smaller than the outside diameter of the inlet 122a of the dust collection filter 120, when the suction port 101b is facing downward, dust accumulated on the dust collection filter 120 is caught by the spill prevention rib 103h, and the dust can be reduced from flowing back toward the suction passage side 103a. Note that the intra-passage protrusion 103f may be provided on the lower case 10a, and a through hole may be provided in the port packing 103. In that case, the intra-passage protrusion 103f can be formed of the hard material of the lower case 10a, so that the effect of suppressing dust leakage can be improved.
[0095] The connecting pipe 101 can be connected to the extension pipe 20. When connecting the extension pipe 20 to the connecting pipe 101, the extension pipe 20 is inserted into the inside of the connecting pipe 101. When the extension pipe 20 is inserted into the inside of the connecting pipe 101, the end of the extension pipe 20 comes into contact with the front lip 103b of the mouth packing 103. This ensures airtightness between the internal passage of the extension pipe 20 and the inlet passage 103a of the mouth packing 103.
[0096] In this embodiment, a flexible mouth gasket 103 is provided between the connecting pipe 101 and the dust collecting section 12, thereby ensuring airtightness between the suction passage 101a of the connecting pipe 101 and the inlet passage 103a of the mouth gasket 103, between the internal passage of the extension pipe 20 and the inlet passage 103a of the mouth gasket 103, and between the inlet passage 103a of the mouth gasket 103 and the inlet 122a of the support plate 122 (dust collecting filter 120).

When the vacuum cleaner 1 is placed on the floor surface Y, the main body central projection 10i and the main body rear projection 10j come into contact with the floor surface Y. When the vacuum cleaner 1 is placed on the floor surface Y, the main body front projection 10h is floating above the floor surface Y, and the vacuum cleaner 1 is supported by the main body central projection 10i and the main body rear projection 10j.
[0101] When replacing the dust collection filter 120, the user places his / her hands on the dust collection case 10c. In other words, when the user places his / her hands on the dust collection case 10c, a force is applied downward to the dust collection case 10c. Therefore, in this embodiment, a main body front protrusion 10h is provided to receive the force applied to the dust collection case 10c when replacing the dust collection filter 120. When a force is applied to the dust collection case 10c, the main body front protrusion 10h comes into contact with the floor surface Y and supports the vacuum cleaner 1 together with the main body center protrusion 10i and the main body rear protrusion 10j.
[0102] In this embodiment, the main body rear projection 10j (first leg) is provided on the bottom surface of the battery pack 16, the main body central projection 10i (second leg) is provided on the bottom surface behind the dust collecting unit 12, and the main body front projection 10h (third leg) is provided on the front bottom surface of the dust collecting unit 12. The arrangement positions are not limited to those in this embodiment.
[0103] According to this embodiment, a front body protrusion 10h, a central body protrusion 10i, and a rear body protrusion 10j are provided which protrude downward from the bottom of the vacuum cleaner 1 (vacuum cleaner body 10), and these are arranged in a line in the front-to-rear direction of the vacuum cleaner 1 (vacuum cleaner body 10), so that the dust collection filter 120 can be replaced while the vacuum cleaner 1 is stabilized. EXAMPLES
[0104] A third embodiment will be described with reference to FIG. 1 and FIG. 19 to FIG. 22. In the third embodiment, the configuration of the stand will be described. FIG. 19 is an external perspective view of the stand 50 according to the third embodiment of the present invention as seen from the left front. FIG. 20 is a front view of the stand 50 according to the third embodiment of the present invention as seen from the front. FIG. 21 is an external perspective view of the upper part of the stand 50 according to the third embodiment of the present invention as seen from the left front. FIG. 22 is an external perspective view of the upper part of the stand 50 according to the third embodiment of the present invention as seen from the right rear. FIG. 23 is an external perspective view of the dust collection filter storage box 54 as seen from the left front. In FIG. 19 to FIG. 22, the front-rear, left-right, and up-down directions are determined based on the stand 50. When the electric vacuum cleaner 1 is used as a reference, the up-down directions shown in FIG. 19 to FIG. 22 coincide with the front-rear direction of the electric vacuum cleaner 1, and the up-down directions shown in FIG. 19 to FIG. 22 coincide with the up-down direction of the electric vacuum cleaner 1.
[0105] The stand 50 is composed of a base portion 51 that is placed on the floor surface, a support pillar 52 that is connected to the base portion 51 and extends upward from the base portion 51, and a holder portion 53 that is connected to the upper portion of the support pillar 52.
[0106] 1, the vacuum cleaner 1 is stored in the stand 50 by standing it up with its front facing downward. The holder portion 53 is provided with a main body receiving portion 531 that receives the vacuum cleaner main body 10 of the vacuum cleaner 1, a main body storing portion 532 in which the lower portion of the vacuum cleaner main body 10 is stored, and a protrusion receiving portion 533 that receives the main body central protrusion 10i. The main body receiving portion 531 is formed in a curved shape so as to come into contact with the decorative cover 10g of the vacuum cleaner main body 10.
[0107] The projection receiving portion 533 is provided with a fixing rib 534 that is inserted into a fixing groove 10k (see Figs. 7, 10, 17, and 18) provided in the main body central projection 10i when the vacuum cleaner 1 is stored in the stand 50, and fixes the vacuum cleaner 1. The projection receiving portion 533 is also provided with a charging terminal 60 that connects to the DC jack 19 provided in the main body central projection 10i and charges the battery pack 16 when the vacuum cleaner 1 is stored in the stand 50. A wiring storage portion 521 is provided behind the support pillar 52, and a wiring fixing portion 537 is provided behind the holder portion 53, and stores wiring electrically connected to the DC jack 19. The wiring storage portion 521 is formed behind the support pillar 52 so as to extend in the vertical direction.
[0108] The vacuum cleaner of this embodiment uses a disposable dust collection filter 120. The dust collection filter 120 is replaced when the filter becomes full of dust and the suction power decreases. For this reason, a replacement dust collection filter must be prepared for the vacuum cleaner, and securing a storage space for the replacement dust collection filter has been an issue. Therefore, in this embodiment, a space for storing the replacement dust collection filter 120 is secured in the holder portion 53 of the stand 50. Note that, in this embodiment, the stand 50 also functions as a charging stand provided with a charging terminal 60, but is not limited to this, and may not have the charging terminal 60.
[0109] The dust collection filter storage box 54 is provided on the left side surface (outer peripheral surface) of the holder part 53, and is supported rotatably so as to protrude from the storage space 535 to the outside of the holder part 53. The dust collection filter storage box 54 includes a storage section 541 that is open at the top and stores a plurality of dust collection filters 120, a front cutout section 542 in which the front surface is cut out, a rotation shaft 543 that rotates the dust collection filter storage box 54, and a regulating protrusion 544 that stops the rotating dust collection filter storage box 54 at a predetermined position, which are provided in front and behind the left lower part (outer lower part) of the dust collection filter storage box 54. The regulating protrusion 544 is disposed on the inside of the rotation shaft 543. The regulating protrusion 544 is also formed with an inclined section 544a that is inclined from the top to the bottom so as to descend outward.
[0110] A rotation restricting portion 536 that comes into contact with the restricting protrusion 544 is formed on the left side (outer periphery) of the holder portion 53 as shown in Fig. 22. Although the rotation restricting portion 536 is shown only on the rear side of the holder portion 53 in Fig. 22, a similar rotation restricting portion is also provided on the front side.
[0111] In the storage section 541 of this embodiment, a total of six folded dust collection filters 120 are stored, three in the front-rear direction and two in the up-down direction. The outer periphery of the dust collection filter storage box 54 is higher in the up-down direction than the height of the two dust collection filters 120 stacked in the up-down direction, and the dust collection filters 120 are hidden when the dust collection filter storage box 54 is stored. The replacement dust collection filters 120 are sold in a package of six dust collection filters. Therefore, in this embodiment, the six packaged dust collection filters are designed to fit directly into the storage section 541. The remaining amount of dust collection filters 120 can be checked through the front cutout portion 542.
[0112] When removing the dust collection filter 120 from the storage section 541, the dust collection filter storage box 54 is rotated around the rotation shaft 543 as a fulcrum. The dust collection filter storage box 54 rotates so that the upper part 54a protrudes outward from the holder section 53. By rotating, the dust collection filter storage box 54 can be rotated to a removal position where the dust collection filter 120 can be removed and a storage position. The upper part 54a of the dust collection filter storage box 54 is formed so as to be inclined downward from the outer periphery side toward the inner periphery side. By configuring in this way, the rotation trajectory of the dust collection filter storage box 54 can be made small, and interference with the holder section 53 can be suppressed when the dust collection filter storage box 54 rotates.
[0113] When the dust collection filter storage box 54 rotates, the inclined portion 544a of the restricting protrusion 544 comes into contact with the rotation restricting portion 536, and the rotation of the dust collection filter storage box 54 stops. At this time, it is preferable that the center of gravity of the dust collection filter storage box 54 is positioned above the vertical center of the dust collection filter storage box 54. If the center of gravity of the dust collection filter storage box 54 is positioned above, the dust collection filter storage box 54 can be maintained in an outwardly open state, and the dust collection filter 120 can be easily removed from the storage portion 541.
[0114] In particular, with the shape of this embodiment, when three dust collecting filters 120 are stored in the dust collecting filter storage box 54, the center of gravity of the dust collecting filter storage box 54 and the dust collecting filter 120 is closest to the holder portion 53. Even in this case, since the center of gravity is located outside the rotation axis, the dust collecting filter storage box 54 can be maintained in an outwardly open state, making it easy to remove the dust collecting filter 120 from the storage portion 541.
[0115] When removing the dust collection filter 120 stored in the lower stage of the storage section 541, it can be removed by inserting a finger through the front cutout section 542 and pulling it upward.
[0116] Furthermore, in order to make it easy to remove the dust collection filter 120 from the storage section 541, the height H from the floor surface of the dust collection filter storage box 54 is preferably set to 70 cm or more. This allows the storage box 54 to be located close to the user's hands, making it easy to remove the dust collection filter 120.
[0117] In addition, the maximum protrusion amount of the dust collection filter storage box 54 when opened outward is preferably set inside the extension line L of the base part 51 so as not to protrude from the extension line L of the base part 51. There is a possibility that the stand 50 will be installed close to a wall. If the maximum protrusion amount of the dust collection filter storage box 54 is set not to protrude from the extension line L of the base part 51, the dust collection filter 120 can be taken out of the dust collection filter storage box 54 even if the stand 50 is installed close to a wall.
[0118] According to this embodiment, since the dust collecting filter 120 is stored in the stand 50, the workability of replacing the dust collecting filter 120 can be improved.
[0119] In this embodiment, the dust collecting filter storage box 54 is rotated around the rotation axis 543 as a fulcrum, but the present invention is not limited to a rotational system, and may be configured such that the dust collecting filter storage box 54 is moved by a slide between a storage position and a removal position for removing the replacement dust collecting filter 120.
[0120] The present invention is not limited to the above-mentioned embodiment, and various modifications are included. For example, the above-mentioned embodiment has been described in detail to easily explain the present invention, and is not necessarily limited to those having all the configurations described. In addition, it is possible to replace a part of the configuration of one embodiment with the configuration of another embodiment, and it is also possible to add the configuration of another embodiment to the configuration of one embodiment. In addition, it is possible to add, delete, or replace a part of the configuration of each embodiment with another configuration. [Explanation of symbols]
