Description

Technical Field

[0001] The present invention relates to a vacuum cleaner.

Background Art

[0002] As a vacuum cleaner in which a user holds a handle portion provided on a cleaner main body to perform cleaning, there is a stick-type vacuum cleaner. The stick-type vacuum cleaner includes an electric blower and a dust collection unit in the cleaner main body, and collects dust sucked from a suction port body through an extension pipe connected to the cleaner main body in the dust collection unit.

[0003] In addition, a general stick-type vacuum cleaner can also be used as a handy-type vacuum cleaner that removes an extension pipe connected to the cleaner main body and sucks dust from the suction port of the cleaner main body.

[0004] In a stick-type vacuum cleaner, it is common that the electric blower, the dust collection unit, and the suction port are in a straight line. Such a vacuum cleaner is disclosed in, for example, Patent Document 1.

Summary of the Invention

Problems to be Solved by the Invention

[0006] When using the vacuum cleaner disclosed in Patent Document 1, the user holds the handle portion behind the cleaner main body and tilts the cleaner main body with the front side down to suck dust from the suction port of the cleaner main body.

[0007] However, in the vacuum cleaner disclosed in Patent Document 1, since the dust collection part and the suction port are arranged in a straight line, there is a problem that the dust that has once entered the dust collection part leaks out by tilting the cleaner body. In order to avoid this, it is conceivable to shift the central axis of the dust collection part and the central axis of the suction port. When the central axis of the dust collection part and the central axis of the suction port are shifted, in order to stably place the cleaner body on the floor surface, it is conceivable to provide legs on the cleaner body. In this case, when performing maintenance of the cleaner body, such as replacing the dust collection filter, a downward force is applied to the cleaner body, and there is a possibility that the cleaner body may be damaged because the legs cannot support the force, and it is necessary to prevent this.

[0008] An object of the present invention is to provide a vacuum cleaner that can prevent damage during maintenance work when the cleaner body is placed on the floor surface.

Means for Solving the Problems

[0009] In order to achieve the above object, the present invention provides a vacuum cleaner including a cleaner body, an electric blower provided in the cleaner body, a dust collection part provided in the cleaner body for collecting dust sucked by the suction force generated by the electric blower, and a battery part provided in the cleaner body for supplying power to the electric blower. In the vacuum cleaner, the battery part includes a first leg, the cleaner body includes a second leg behind the dust collection part, and the dust collection chamber includes a third leg.

Effects of the Invention

[0010] According to the present invention, damage during maintenance work when the cleaner body is placed on the floor surface can be prevented.

Mode for Carrying Out the Invention

[0012] Hereinafter, examples of the present invention will be described with reference to the drawings. For the same elements, the same reference numerals are generally given in all the drawings. Also, the description of the parts having the same function will be omitted. Note that the configurations described below are merely examples, and it is not intended that the embodiments according to the present invention be limited to the following specific forms.

Examples

[0013] FIG. 1 is an external perspective view of a vacuum cleaner in a state of being stored in a stand according to Embodiment 1 of the present invention. FIG. 2 is an external perspective view of a vacuum cleaner in a state of being used as a stick type according to Embodiment 1 of the present invention. FIG. 3 is an external perspective view of a vacuum cleaner in a state of being used as a handy type according to Embodiment 1 of the present invention. FIG. 4 is a cross-sectional view of the cleaner body 10 of the vacuum cleaner 1 cut along the front-rear direction. In Embodiment 1, the front-rear, left-right, and up-down directions are defined from the viewpoint of the user performing cleaning with the vacuum cleaner 1 as a reference, as indicated by the arrows.

[0014] There is a stick-type vacuum cleaner as an electric vacuum cleaner in which the user holds the handle portion provided on the cleaner body to perform cleaning. The stick-type vacuum cleaner includes an electric blower and a dust collection portion in the cleaner body, and collects dust sucked from the suction port body through an extension pipe connected to the cleaner body in the dust collection portion.

[0015] In addition, a general stick-type vacuum cleaner can also be used as a handy-type vacuum cleaner that removes the extension pipe connected to the cleaner body and sucks dust from the suction port of the cleaner body.

[0016] As shown in FIGS. 1 and 2, the vacuum cleaner 1 includes a cleaner body 10 that constitutes an outer shell, an extension pipe 20 having one end connected to the cleaner body 10 via a connection pipe 101, and a suction port body 30 connected to the other end of the extension pipe 20. The suction port body 30 incorporates a rotating cleaning body (not shown) and a motor that drives this rotating cleaning body, and power is supplied from a storage battery through a lead wire disposed in the extension pipe 20.

[0017] In addition, the vacuum cleaner 1 of Embodiment 1 is provided with a brush portion 40 (omitted in FIG. 1) on the outer periphery of the connection pipe 101. The connection pipe 101 is fixed in front of the cleaner body 10, and a suction passage 101a through which air flows is formed inside the connection pipe 101 and communicates with the internal passage of the extension pipe 20.

[0018] The extension tube 20 is connected to the cleaner main body 10 via the connecting tube 101. The vacuum cleaner 1 is placed on the stand 50 when not in use. At the upper part of the connecting tube 101, when the extension tube 20 is connected, there is a lock button 102a for preventing the extension tube 20 from coming out, and a button cover 102 covering the lock button 102a.

[0019] The cleaner main body 10 is composed of an outer shell formed by a lower case 10a, an upper case 10b arranged above the lower case 10a, and a dust collection part case 10c arranged on the front side of the lower case 10a. In the lower case 10a, there are a motor chamber 10f (motor blower housing part) for housing the motor blower 14 and an exhaust port is formed. In the dust collection part case 10c, a pack chamber 10e for housing the dust collection filter 120 is formed.

[0020] In addition, the cleaner main body 10 includes a dust collection part 12 for collecting the sucked dust, a dust collection lid 11 that can open and close the upper part of the dust collection part 12, and a handle part 13 that the user grips when cleaning. The dust collection part 12 is formed by the dust collection part case 10c, and a pack chamber 10e is formed in the dust collection part 12.

[0021] The handle part 13 is formed by a part of the upper case 10b.

[0022] The dust collection lid 11 opens and closes around the rotation axis 105, and is urged in the direction of opening the dust collection lid 11 by a coil spring 110 (Figure 8) described later. In addition, the dust collection lid 11 is held in a closed state of the dust collection part 12 by a dust collection lid clamp 112. The lower case 10a forming the lower side of the dust collection part 12 is provided with a dust collection part packing 127 (Figure 8). When the dust collection lid 11 is closed, the dust collection lid 11 contacts the dust collection part packing 127 to keep the airtightness inside the dust collection part 12.

[0023] The dust collection lid 11 is formed of a translucent member, so that the swelling of the dust collection filter 120 can be confirmed, and the design can be further improved.

[0024] Near the rear of the dust collection lid claw 11a caught by the dust collection lid clamp 112, a rib 10d provided on the button cover 102 is formed. When the user lifts the vacuum cleaner 1 by holding the handle portion 13 when using it as a stick type, by pressing the dust collection lid claw 11a with the rib 10d, it is possible to prevent the entire cleaner body 10 from warping and the dust collection lid claw 11a from coming off the dust collection lid clamp 112.

[0025] Inside the cleaner body 10, an electric blower 14 (Fig. 4) that generates suction force, a control board 15 (Fig. 4) on which a control device for controlling the electric blower 14 is mounted, and a plurality of battery packs 16 (battery unit) that are located on the rear side of the electric blower 14 and supply power to the electric blower 14 are provided.

[0026] The battery pack 16 is fixed by a battery clamp 114. By pressing the battery attachment / detachment button 113, the battery clamp 114 moves in conjunction, the fixed part of the battery pack 16 comes off, and the battery pack 16 can be removed. Thus, when the user owns a plurality of battery packs 16, they can operate for a long time by replacing them. Also, when the battery pack 16 reaches the end of its life, the user can easily replace it with a new battery pack 16.

[0027] On the handle portion 13, an operation switch 17 for turning the electric blower 14 on and off and adjusting the suction force is arranged.

[0028] As shown in Fig. 4, the dust collection part 12 is detachably provided with a disposable dust collection filter 120 that collects and filters the dust sucked from the suction passage 101a. The dust collection filter 120 has air permeability and flexibility, and is composed of a bag member 121 for storing dust and a support plate 122 with an inlet 122a formed in the central part. The support plate 122 is inserted along a guide groove described later, and the upper part is fixed to the dust collection part 12 by a support plate clamp (support plate fixing part) 104.

[0029] The dust collection filter 120 is attached to the dust collection unit 12 by fixing the support plate 122 with the support plate clamp 104.

[0030] With the central axis of the suction passage 101a (central axis A of the suction port 101b) horizontal, the support plate 122 is inclined so that the upper part is located behind the lower part and is attached to the dust collection unit 12. In other words, the central axis A of the suction port 101b and the central axis E of the dust collection filter 120 and the support plate 122 are not parallel, but are inclined at approximately 20° (different angles).

[0031] Also, between the connection pipe 101 and the dust collection unit 12, there are provided a mouth packing 103 that forms an inflow passage 103a, and a holding member 1030 that is disposed on the outer periphery of the mouth packing 103 and holds the mouth packing 103.

[0032] The mouth packing 103 is formed with an inflow passage 103a (central axis C) that communicates the suction passage 101a of the connection pipe 101 with the dust collection unit 12, and a rear lip 103c (central axis E) that abuts against the support plate 122. The mouth packing 103 communicates the suction passage 101a of the connection pipe 101 with the dust collection unit 12.

[0033] Also, the mouth packing 103 is formed of a flexible member. For example, using SBR as a flexible member and providing a mating surface of the mold on the inflow passage 103a side and the mold on the rear lip 103c side on the side surface of the check valve 103d, a thin plate portion can be generated on the side surface of the check valve 103d, and the clearance between the check valve 103d and the inflow passage 103a can be reduced by the thin plate portion serving as a thread rib. By reducing the clearance between the check valve 103d and the inflow passage 103a, it is possible to prevent the dust deposited on the dust collection filter 120 from flowing back to the inflow passage 103a side. A lip-shaped rear lip 103c is provided at the rear tip of the mouth packing 103, and airtightness is maintained by abutting against the support plate 122.

[0034] When maintaining airtightness at the inlet 122a, it is not necessary to use the orifice packing 103. For example, an airtightness maintaining mechanism 1032 (Fig. 24) composed of a holding member 1030 and an elastic member 1031 connected to the front side (connection pipe 101 side) of the holding member 1030 can also maintain airtightness. By fixing the end of the elastic member to the connection pipe 101, the elastic force of the elastic member 1031 can press the holding member 1030 connected to the elastic member against the support plate 122. As a result, airtightness is maintained by the contact between the rear side (guide member side) end of the holding member 1030 and the support plate 122.

[0035] Also, a groove in the shape of the end of the holding member 1030 can be formed in the support plate 122. By fitting the end of the holding member 1030 into the groove, the escape path of air can be blocked, and the airtightness can be further improved.

[0036] The dust sucked from the suction port 101b of the suction passage 101a passes through the suction passage 101a and the inflow passage 103a of the orifice packing 103 together with the air, and is collected in the bag member 121 of the dust collecting filter 120 from the inlet 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 protection filter 180 and the opening 12b for the electric blower, and is sucked by the electric blower 14. The protection filter 180 is disposed between the dust collecting filter 120 and the opening 12b for the electric blower to prevent the dust leaking from the bag member 121 from being sucked by the electric blower 14. The protection filter 180 is supported by a filter frame 18 that can slide substantially in the vertical direction and is mounted on the dust collecting portion 12.

[0037] The electric blower 14 includes a fan 141 that generates a suction force and an electric motor 143 that is connected to the fan 141 via a rotating shaft 142 and rotates the fan 141. The rotation center line D of the rotating shaft 142 of the electric blower 14 is inclined so as to descend toward the downstream side (rear side).

[0038] On the downstream side (rear side) of the electric blower 14, a battery pack 16 that supplies power to the electric blower 14 is provided.

[0039] When used as a stick-type electric vacuum cleaner, as shown in FIG. 2, a suction body 30 is connected to the connecting pipe 101 of the cleaner main body 10 via an extension pipe 20. The user holds the handle portion 13, operates the operation switch 17 to drive the electric blower 14, and moves the suction body 30 in the front-rear direction. Due to the suction force of the electric blower 14, a suction force is generated in the suction body 30. The dust sucked from the suction body 30 passes through the extension pipe 20 and is collected by the dust collection filter 120 of the dust collection portion 12.

[0040] When used as a handy-type electric vacuum cleaner, as shown in FIG. 3, the extension pipe 20 is removed from the connecting pipe 101 of the cleaner main body 10. By removing the extension pipe 20 from the connecting pipe 101, the suction port 101b of the suction passage 101a is exposed. The user holds the handle portion 13, operates the operation switch 17 to drive the electric blower 14, and moves the connecting pipe 101. Then, dust is directly sucked from the suction port 101b, and the sucked dust is collected by the dust collection filter 120 of the dust collection portion 12.

[0041] In a general electric vacuum cleaner, since the support plate 122 is perpendicular to the central axis A of the suction port 101b, in that state, the upper surface of the cleaner main body is formed to gradually bulge upward as it goes from the suction port of the cleaner main body to the rear of the cleaner main body so that the bag member 121 can bulge sufficiently and the dust collection capacity can be ensured. Therefore, when used as a handy-type electric vacuum cleaner, there is a problem that the suction port cannot be seen and it is difficult to clean the dust on the floor surface. A configuration for solving this problem will be described with reference to FIG. 4.

[0042] In FIG. 4, when the central axis of the suction port 101b is A and the central position of the inlet of the dust collecting 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 collecting 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 on the handle portion 13 side with respect to the central position B of the inlet of the dust collecting filter 120 (the central position of the inlet 122a of the support plate 122). Further, the central axis E of the dust collecting filter 120 (the central axis of the inlet 122a of the support plate 122) is inclined so as to descend toward the downstream side with respect to the central axis A of the suction port 101b.

[0043] Since a mouth packing 103 that is inclined downward toward the downstream side (rear side) is formed between the downstream side (rear side) of the suction passage 101a and the inlet 122a of the dust collecting filter 120, the central position B of the inlet of the dust collecting filter 120 is positioned below the central axis A of the suction port 101b.

[0044] According to the first embodiment, since the central axis A of the suction port 101b is positioned above the central position B of the inlet of the dust collecting filter 120 (the central position of the inlet 122a of the support plate 122), when used as a handy type electric vacuum cleaner, the suction port 101b is more visible from the user's line of sight, and the operability during cleaning can be improved.

[0045] Further, according to the first embodiment, since the upper surface of the suction port 101b is formed linearly toward the handle portion 13 side (rear side) without unevenness, the design property can be improved.

[0046] Furthermore, according to the first embodiment, since the central axis A of the suction port 101b and the central position B of the inlet of the dust collecting filter 120 are displaced from each other, when the cleaner main body 10 is stood up so that the suction port 101b is at the bottom, it is possible to suppress the dust collected by the dust collecting filter 120 from spilling out from the inlet 122a and the spilled dust from being discharged to the outside from the suction port 101b.

[0047] Furthermore, in Example 1, when the central axis of the dust collection filter 120 is E, the central axis A of the suction port 101b and the central axis E of the dust collection filter 120 are configured not to be parallel. By configuring it in this way, when the dust collection filter 120 is taken out from the dust collection unit 12, it is possible to suppress the dust collected on the dust collection filter 120 from spilling out from the inflow port 122a and the spilled dust from being discharged to the outside from the suction port 101b.

[0048] In Example 1, since the user grips the handle portion 13 to operate the vacuum cleaner 1, a moment is applied to the user's hand. Therefore, 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. Thus, in Example 1, 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 of Example 1 is configured to intersect the extension line of the central axis A of the suction port 101b. By configuring as described above in Example 1, the moment applied to the user's hand can be reduced, and the operability of the vacuum cleaner can be improved.

[0049] In the vacuum cleaner 1, in order to improve the dust collection efficiency, it is preferable to reduce the ventilation loss. Thus, in Example 1, 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 it 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. In order 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 a vacuum cleaner equipped with a storage battery, by improving the dust collection efficiency, the operating time of the electric blower 14 can be reduced, and the weight of the vacuum cleaner due to the miniaturization of the storage battery can be reduced.

[0050] The central axis C of the inflow passage 103a of the orifice 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.

[0051] In addition, in the vacuum cleaner 1, in order to ensure the dust collection amount, it is desirable to increase the size of the dust collection unit 12. However, in order to suppress a decrease in operability, it is preferable that the cleaner main body 10 is not made larger than necessary. Therefore, in the first embodiment, the central axis C of the inlet passage 103a of the mouth packing is configured at an angle (substantially 25° with respect to the central axis A) that is further rearward than the central axis E of the support plate 122 of the dust collection filter 120. That is, 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. By adopting such a configuration, it is possible to suppress the length in the front-rear direction of the inlet passage 103a while ensuring the area of the support plate 122, so that the size of the dust collection unit 12 can be increased while suppressing the length of the cleaner main body 10.

[0052] In addition, it is desirable that the vacuum cleaner 1 is small in size. The battery pack 16 housed in the cleaner main body 10 is larger in volume than the electric blower 14 in order to ensure the battery capacity, which tends to increase the size of the cleaner main body 10. 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 suppress the swelling of the portion of the cleaner main body 10 that houses the battery pack 16, and to suppress the increase in size of the cleaner main body 10. Further, 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 made 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 is larger in volume than the electric blower 14. Therefore, 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. Thereby, an increase in size of the vacuum cleaner 1 can be suppressed.

[0053] In addition, it is desirable that the vacuum cleaner 1 is lightweight. By providing irregularities on the inner sides of the lower case 10a and the upper case 10b that form the outer shell so that the wall thickness of the outer shell changes (by topology lightweighting technology), the weight can be reduced. It is desirable that the irregularities have a thick wall in the portions where strength is required and a thin wall in the unnecessary portions, and the shape may be determined by simulation.

[0054] Note that point P1 in FIG. 4 indicates the center of gravity in the handy state, and point P2 indicates the center of gravity in the stick state.

[0055] Also, according to the first embodiment, in a state where the central axis A of the suction port 101b is horizontal, the central axis E of the support plate 122 is configured to incline within a range of 5° to 76.5° such that the upper part of the support plate 122 is located behind the lower part. As a result, when the support plate clamp 104 is opened, the guide member 128 easily rotates toward the removal position due to the self-weight of the guide member 128 and the dust collection filter 120, and the inflow port 122a faces upward of the main body, so that dust is less likely to spill. Furthermore, an inclination within a range of 10° to 40° is desirable. In this embodiment, the inclination is set to approximately 20°.

[0056] Next, with reference to FIGS. 5 and 6, the configuration of the dust collection filter 120 and the dust collection unit 12 will be described. FIG. 5 is an external perspective view of the folded dust collection filter 120 according to the first embodiment of the present invention. FIG. 6 is an external perspective view of the dust collection filter 120 when it is discarded according to the first embodiment of the present invention.

[0057] The dust collection filter 120 includes a quadrilateral support plate 122 made of cardboard, plastic, etc. having an inflow port 122a, a breathable bag member 121 made of non-woven fabric such as paper, cloth, animal hair, or plastic material, and a seal member 123 attached to the support plate 122. The bag member 121 is adhered to the back side of the support plate 122. In the second embodiment, the seal member 123 is attached to any one piece of the quadrilateral support plate 122. Also, in the second embodiment, although the seal member 123 is attached to the support plate 122, it may be attached by adhering to a part of the bag member 121.

[0058] The adhered portion of the bag member 121 and the support plate 122 does not extend over the entire support plate 122, and the outer peripheral portion of the support plate 122 is not adhered to the bag member 121. The bag member 121 is adhered around the opening of the support plate 122. When the support plate 122 is mounted on the dust collection portion 12 of the vacuum cleaner 1, it is caught and fixed by the claw portion of the support plate clamp 104. However, if the bag member 121 is adhered up to the outer peripheral end of the support plate 122, the claw portion of the support plate 122 and the support plate clamp 104 cannot be hooked, and there is also a risk of damaging the bag member 121 with the claw portion of the support plate clamp 104. For this reason, in the second embodiment, the outer peripheral portion of the support plate 122 is not adhered to the bag member 121. The portion where the support plate 122 and the bag member 121 are not adhered needs to be at least one side of the support plate 122, that is, the side caught by the claw portion of the support plate clamp 104, but the other sides may be adhered up to the ends of the support plate 122.

[0059] The seal member 123 is attached to the back surface side of the support plate 122 at the portion where the support plate 122 and the bag member 121 are not adhered. In the second embodiment, it is the upper side of the back surface of the support plate 122. When adhering the seal member 123 to the upper side of the back surface of the support plate 122, it is preferable not to adhere near the ends of the support plate 122. The reason for this is that since the upper side of the support plate 122 is caught and fixed by the claw portion of the support plate clamp 104, in order not to damage the seal member 123, it is preferable not to adhere the portion caught by the claw portion of the support plate clamp 104 between the support plate 122 and the seal member 123.

[0060] The seal member 123 includes a seal portion 124 having an adhesive surface which is glue, 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 on the front side of the support plate 122 and the seal portion 124 is on the back side of the support plate 122 with the glue as the boundary. A hook hole 126 for hooking onto a protrusion 104a provided on the support plate clamp 104 of the vacuum cleaner 1 is formed in the release paper 125. The release paper 125 may be fixed to components other than the support plate 122. Further, the fixing method may be to provide an adhesive portion on the release paper 125 and attach it to the component to be fixed, or to provide a mechanism for sandwiching the release paper 125 with the component to be fixed. By providing a seal member fixing portion for fixing such a release paper 125, a part of the seal member 123 for sealing the opening of the support plate 122 can be fixed, and the opening can be sealed when replacing the dust collection filter.

[0061] When the release paper 125 of the seal member 123 is peeled off from below (the hook hole 126 side), the adhesive surface of the seal portion 124 is exposed. Then, the seal portion 124 is folded back at the upper part of the support plate 122, the exposed adhesive surface is opposed to the front surface of the support plate 122, and the adhesive surface of the seal portion 124 is attached to the support plate 122. Since the inlet 122a of the support plate 122 is covered and blocked by the seal portion 124, it is possible to suppress dust from leaking out of the inlet 122a even when the dust collection filter 120 is discarded, and it can be handled hygienically.

[0062] It is preferable that the closing of the inlet 122a of the support plate 122 by the seal portion 124 operates when the dust collection filter 120 is taken out from the dust collection portion 12 of the vacuum cleaner 1. The operation of taking out the dust collection filter 120 will be described with reference to FIGS. 7 to 11.

[0063] FIG. 7 is a view showing a state in which the dust collection filter 120 is taken out from the dust collection unit 12 of the vacuum cleaner 1 according to Embodiment 1 of the present invention. FIG. 8 is an enlarged view of a main part of FIG. 7 showing the opening operation function of the dust collection lid 11 and the structure of the guide member 128. FIG. 9 is an exploded perspective view of a state in which the filter frame 18 and the protection filter 180 are removed from the vacuum cleaner 1 according to Embodiment 1 of the present invention. FIG. 10 is a perspective view of the vacuum cleaner 1 according to Embodiment 1 of the present invention as viewed from the rear side. FIG. 11 is a side view showing the operation of the filter frame 18 when pulling out the dust collection filter 120 in a state where the bag member 121 is inflated, where (A) shows a state before pulling out the dust collection filter 120 and (B) shows a state after pulling out the dust collection filter 120.

[0064] The dust collection unit 12 is provided with a guide member 128 for guiding the support plate 122 of the dust collection 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 collection filter 120 is inserted, and a guide groove 128b for guiding 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. Rotating shafts 128c for rotatably supporting the guide member 128 are provided on both the left and right sides below the guide member 128. The dust collection filter 120 can be removed when the angle formed by the mounting position and the removal position of the guide member 128 is in the range of 5° to 25°. Further, when it 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 during a series of operations of replacing the dust collection filter 120. In this embodiment, it is set to 13.5°.

[0065] Also, when 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 in a state where the guide member 128 is in the removal position, the dust collection filter 120 can be removed. Further, when it is 2.8 mm or more and 14.6 mm or less, the operability of the dust collection filter is improved, and dust is less likely to spill during a series of operations of replacing the dust collection filter. In this embodiment, it is set to 7.1 mm.

[0066] When attaching the dust collection filter 120 to the dust collection unit 12 of the vacuum cleaner 1, open the dust collection lid 11, insert the support plate 122 of the folded dust collection filter 120 (Fig. 5) along the insertion part 128a and the guide groove 128b of the guide member 128, and make it face the outlet part of the mouth packing 103. Then, rotate the guide member 128 forward, hook and fix the upper part of the support plate 122 on the claw part of the support plate clamp 104. Also, hook the hook hole 126 formed in the release paper 125 on the protrusion 104a of the support plate clamp 104. Then, close the dust collection lid 11.

[0067] As shown in Fig. 8, the dust collection lid 11 is biased in the opening direction by the coil spring 110. The coil springs 110 are arranged in two side-by-side positions in the left-right direction. One lower tip 110a of the coil spring 110 is hooked on the fixing part 106 of the cleaner main body 10, and the other upper tip 110b is in contact with the dust collection lid 11. With this configuration, the dust collection lid 11 is biased in the opening direction. Also, the upper tip 110b of the coil spring 110 on the dust collection lid 11 side is bent toward the dust collection unit 12 side. Thereby, during manufacturing and assembly, after attaching the coil spring 110 to the fixing part 106, when attaching the dust collection lid 11 while pressing the tip of the coil spring, the bent part serves as a guide, making it easy to attach.

[0068] Also, the rotation shaft 128c of the guide member 128 is provided rotatably at the position of the front inner wall 12d of the dust collection unit 12. The front inner wall 12d of the dust collection unit 12 is inclined so as to descend 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 arranged on the inclined front inner wall 12d.

[0069] For example, when replacing the dust collecting filter 120, dust may spill from the inlet 122a of the support plate 122 and fall downward, accumulating near the rotation shaft 128c. When dust accumulates near the rotation shaft 128c, it becomes difficult for the guide member 128 to rotate. Therefore, in this embodiment, the rotation shaft 128c is disposed on the inclined front inner wall 12d. In this embodiment, the dust that spills from the inlet 122a and falls downward does not stay on the rotation shaft 128c but moves downward along the rotation shaft 128c along the inclined front inner wall 12d, so that the rotation operation of the guide member 128 can be stabilized.

[0070] On the inner wall 12a of the dust collection part 12 partitioned from the electric blower 14, a communication opening 151 is formed which communicates with the space for housing the control board 15. In the electric vacuum cleaner 1, the control software written on the control board 15 may be rewritten for maintenance or defect improvement. In this embodiment, it is configured such that a tool can be inserted through the communication opening 151 to rewrite the control software. Note that the communication opening 151 is arranged outside the dust collection part packing 127, so that it has nothing to do with the airtight structure of the dust collection part 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 pasted so as to close the communication opening 151. On the label 152, the model of the dust collection filter 120 to be installed in the dust collection part 12 is described. The user can purchase the replacement dust collection filter 120 by looking at the model described on the label 152. Also, since the user can easily confirm the model, it is possible to prevent the dust collection filter 120 of a different model from being mistakenly installed. The pasting surface of the label 152 is inclined so that the upper side is on the rear side with respect to the lower side with respect to the line orthogonal to the rotation center line D of the rotation shaft 142 of the electric blower 14 (see Fig. 4). Thereby, the model described on the label 152 is made easy for the user to see. Similarly, the pasting surface of the label 152 is inclined so that the upper side is on the rear side with respect to the lower side with respect to the line orthogonal to the parallel line F of the control board 15 (see Fig. 4). Thereby, the position of the control software rewriting connector (not shown) on the control board 15 becomes easy to grasp, and the workability can be improved. Therefore, the pasting surface of the label 152 is not orthogonal 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.

[0071] Also, an opening 12b for the electric blower is formed in the inner wall 12a of the dust collection part 12, and the opening 12b for the electric blower is located on the front side of the electric blower 14. The opening 12b for the electric blower has a lattice shape in order to prevent the user from accidentally putting a finger into the electric blower 14 while securing an air inflow path.

[0072] When the electric blower 14 is driven to generate a suction force, the bag member 121 of the dust collection filter 120 bulges due to the suction airflow, and dust is collected on 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 includes a lattice portion 18a having a large opening in the front-rear direction, and the protection filter 180 is supported in contact with the front surface of the lattice portion 18a. Thus, even when the bag member 121 bulges, it abuts against the lattice portion 18a in a form that sandwiches the protection filter 180, preventing the bag member 121 and the protection filter 180 from directly blocking the inlet portion of the electric blower 14, and making it easier to sustain the suction force. Further, the filter frame 18 has an upper surface opening 18b and a side surface opening 18c. Thus, even when the lattice portion 18a having an opening in the front-rear direction is blocked by the bag member 121, it is possible to easily sustain the suction force by sucking air from the surrounding openings.

[0073] In addition, ribs or convex shapes are provided on the dust collection lid 11 and the dust collection case 10c from the front to the rear of the vacuum cleaner 1, respectively. Thus, even when the bag member 121 bulges, the bag member 121 abuts against the convex shape and does not bulge further, preventing the bag member from sticking to the dust collection lid 11 and the dust collection case 10c and blocking the flow path, and making it difficult for the suction force to decrease. In other words, by forming a concave shape serving as a flow path using ribs and convex shapes on the dust collection portion 11 and the dust collection case 10c, it is possible to easily sustain the suction force even when the bag member 121 bulges.

[0074] When the electric blower 14 is driven to generate a suction force, the dust collection lid 11 bends inward due to the negative pressure. Inside the dust collection lid 11, a contact portion 111 that contacts the dust collection portion case 10c of the cleaner main body 10 when the dust collection lid 11 bends is provided. In a state where the electric blower 14 is driven, since the contact portion 111 contacts the dust collection portion case 10c, the opening of the dust collection lid 11 is suppressed.

[0075] 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).

[0076] 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)).

[0077] The filter frame 18 is provided with a convex portion 18e, and a concave portion 12c, which is a substantially rectangular groove, is provided on the inner wall 12a on the side of the electric blower 14 of the dust collection portion 12 (FIG. 9). The concave portion 12c is significantly larger than the convex portion 18e in the substantially vertical direction, and the filter frame 18 is provided in the dust collection portion 12 in such a manner that the convex portion 18e fits into the concave portion 12c. As a result, the filter frame 18 is slidable in the substantially vertical direction, and when the filter frame 18 is pulled out, the convex portion 18e hits the upper end surface of the concave portion 12c to prevent it from coming off. Note that the position of the concave portion 12c does not overlap with the electric blower opening 12b in the left - right direction. Thereby, the substantially vertical size of the concave portion 12c, and thus the sliding range of the filter frame 18, are less likely to be affected by the size of the electric blower opening 12b. In this embodiment, the concave portion 12c is provided on the side of the inner wall 12a on the side of the electric blower 14, but it may be provided on the side surface side of the inner wall 12a. For example, when the size of the electric blower opening 12b in the left - right direction occupies most of the inner wall 12a on the side of the electric blower 14, there is a limit to the space for providing the concave portion 12c on the inner wall 12a on the side of the electric blower 14, but this problem can be avoided by providing the concave portion 12c on the inner wall 12a on the side surface side.

[0078] Further, since 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 wound from the seal portion 124, and further the seal portion 124 is pulled and folded back to the surface side of the support plate 122, and the seal portion 124 adheres to the surface of the support plate 122 to block the inflow port 122a. Thereby, it is possible to suppress dust from leaking out from the inflow port 122a.

[0079] The dust collection filter 120 of this embodiment is a disposable dust collection filter that is replaced when it becomes full of dust. Therefore, it is necessary to prepare a dust collection filter for replacement, but there is a risk of forgetting to buy it. Thus, a sensor for detecting that the dust collection filter 120 has been replaced in the vacuum cleaner 1 may be provided, and the dust collection filter 120 may be automatically ordered according to the number of replacements of the dust collection filter 120. For example, a home server may be installed, the home server and the vacuum cleaner 1 may be wirelessly connected, and the home server may receive information that the dust collection filter 120 has been replaced from the vacuum cleaner 1 and place an order with the retailer.

[0080] The configuration of the dust collection unit 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 collection unit 12 according to Embodiment 1 of the present invention disassembled. FIG. 13 is an exploded perspective view of the state in which the button cover 102 is removed from the connection pipe 101 according to Embodiment 1 of the present invention. FIG. 14 is a perspective view of the state in which the button cover 102 is attached to the connection pipe 101 from the state of FIG. 13. FIG. 15 is a perspective view of the mouth packing 103 according to Embodiment 1 of the present invention as viewed from the front. FIG. 16 is a perspective view of the mouth packing 103 according to Embodiment 1 of the present invention as viewed from the rear.

[0081] An extension pipe 20 is connected to a connection pipe 101 located in front of the cleaner main body 10. In a vacuum cleaner, during cleaning, the reaction force from the surface to be cleaned is transmitted to the connection pipe 101 through the suction port body 30 and the extension pipe 20, so it is necessary to ensure the strength between the cleaner main body 10 and the connection pipe 101.

[0082] To solve this problem, in this embodiment, the connection pipe 101 located in front of the cleaner main body 10 is integrally formed with a dust collection unit case 10c that forms the dust collection unit 12, ensuring the strength between the cleaner main body 10 and the connection pipe 101.

[0083] In addition, in the vacuum cleaner 1 of the present embodiment, since the central axis C (see FIG. 4) of the inflow passage 103a is inclined so as to descend from the front to the rear, it is difficult to integrally form the inflow passage 103a connecting the connection pipe 101 and the dust collection unit 12 as the dust collection unit case 10c. Therefore, in the present embodiment, a holding member 1030 for forming the inflow passage 103a is provided. And, the mouth packing 103 is inserted inside the holding member 1030. The mouth packing 103 covered by the holding member 1030 is attached from the inside of the dust collection unit 12.

[0084] The end of the connection pipe 101 contacts the front lip 103b of the mouth packing 103. Since the mouth packing 103 is formed of a flexible member, when the front lip 103b contacts the connection pipe 101, airtightness can be ensured between the suction passage 101a and the inflow passage 103a.

[0085] On the front side of the dust collection unit case 10c, a decorative cover 10g is provided so as to cover the front side of the dust collection unit case 10c. A notch 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 notch 101c. Fixed protrusions 10g1 are formed on the inner surface (upper side) of the decorative cover 10g. When the decorative cover 10g is attached to the front side of the dust collection unit case 10c, the fixed protrusions 10g1 are inserted into the notch 101c, and the fixed protrusions 10g1 contact and press 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 port body 30 is arranged on the front side of the dust collection unit case 10c, and the lead wire is covered by the decorative cover 10g.

[0086] At the upper opening edge of the dust collection unit case 10c, when the dust collection lid 11 is closed, a dust collection unit packing 127 for contacting the dust collection lid 11 to maintain the airtightness of the dust collection unit 12 is arranged. The front of the dust collection unit packing 127 is arranged between the support plate clamp 104 and the dust collection lid clamp 112, and the rear of the dust collection unit packing 127 is arranged behind the filter frame 18. A packing fixing portion 127a is formed at the front end of the dust collection unit packing 127 (FIGS. 12 and 13).

[0087] Above the connecting pipe 101, a button cover 102 is arranged to cover above the lock button 102a and the dust collection lid clamp 112. When the dust collection lid clamp 112 is arranged above the connecting pipe 101, the dust collection lid clamp 112 covers the packing fixing part 127a at the front end of the dust collection part packing 127. Thereby, the packing fixing part 127a is clamped from above and below by the dust collection part case 10c and the button cover 102, and the front of the dust collection part packing 127 is fixed to the dust collection part case 10c (FIG. 14).

[0088] In this embodiment, the dust collection lid 11 is provided with claw portions facing forward and is structured to be hooked by the dust collection lid clamp 112. However, the claw portions of the dust collection lid 11 may be provided facing backward, and a claw receiving portion may be provided on the button cover 102 to be hooked, so that the structure allows the user to directly open the dust collection lid 11 by hand. In that case, the dust collection lid clamp 112 can be omitted.

[0089] A lead wire (not shown) for supplying power to the suction port is wired between the dust collection part packing 127 and the dust collection part case 10c. Since the dust collection part packing 127 is attached to the dust collection part case 10c side, the lead wire is not visible to the user, and the designability can be ensured.

[0090] Also, the dust collection part packing 127 has a shape in which the left and right sides are lowered downward and the front and rear sides are raised upward. Thereby, while securing the paths of the front inlet and the rear motor inlet part, the left and right sides are lowered, so that the range of the dust collection lid 11 becomes wider, and when the dust collection lid 11 is opened, the user can easily approach the dust collection part 12 and easily replace the dust collection filter 120.

[0091] As shown in FIGS. 15 and 16, the mouth packing 103 includes a front lip 103b that contacts the end of the connecting pipe 101, a rear lip 103c that has a larger diameter than the front lip 103b and contacts the support plate 122 of the dust collecting filter 120, a check valve 103d that suppresses the leakage of the dust collected in the bag member 121 of the dust collecting filter 120, and a check valve connecting portion 103e that connects the check valve 103d and the rear lip 103c.

[0092] Since the mouth packing 103 is formed of a flexible member, when the rear lip 103c contacts the support plate 122, airtightness can be ensured between the inflow passage 103a and the inlet 122a.

[0093] The check valve 103d operates to open toward the downstream side (rear side) with the check valve connection part 103e as a fulcrum. The check valve connection part 103e is convex toward the rear lip 103c side and concave toward the front lip 103b side with respect to the check valve 103d, so that it is easier to operate in the direction of the rear lip 103c compared to the case where the check valve connection part 103e and the check valve 103d are on the same plane. Also, in the inflow passage 103a of the mouth packing 103, passage protrusions 103f protruding toward the side without the inflow passage 103a are provided in pairs on the left and right. Further, the passage protrusions 103f are also provided at diagonal positions with respect to the check valve connection part 103e in the inflow passage 103a. The passage protrusions 103f suppress the opening of the check valve 103d toward the upstream side (front side). Thereby, it is possible to suppress the leakage of the dust collected on the bag member 121 of the dust collecting filter 120. A check valve rib 103g is provided on the front lip 103b side of the check valve 103d, and by ensuring the rigidity of the check valve 103d, noise due to the vibration of the check valve 103d is suppressed. Further, by arranging the passage protrusions 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 side due to the weight of the dust. The passage protrusions 103f are bent toward the front lip 103b side at L, and when the mouth packing 103 is pulled in the direction of the rear lip 103c, the mouth packing 103 is caught by the passage protrusions 103f, and the mouth packing 103 is less likely to come off. The end face on the front lip 103b side of the passage protrusions 103f is chamfered, reducing the flow path loss during suction and reducing the likelihood of the sucked dust being caught by the passage protrusions 103f. The rear lip 103c includes an outer lip 103j and an inner lip 103i. When the dust collecting filter 120 is attached, each lip bends to ensure the airtightness between the mouth packing 103 and the support plate 122. By making the inner diameter of the tip of the inner lip 103i smaller than the outer diameter of the inlet 122a of the dust collecting filter 120 when the dust collecting filter 120 is attached, the flow path loss and the catching of dust on the support plate 122 can be reduced. The mouth packing 103 is provided with an anti-spill rib 103h inside the inner lip 103i.By making the outer diameter of the spill prevention rib 103h smaller than the outer diameter of the inlet 122a of the dust collection filter 120, when the suction port 101b faces downward, the dust deposited on the dust collection filter 120 can be caught by the spill prevention rib 103h, reducing the backflow of dust in the direction of the suction passage side 103a. Note that the in-duct protrusion 103f may be provided on the lower case 10a, and the mouth packing 103 may be configured to have a through-hole. In that case, since the in-duct protrusion 103f can be formed of the hard material of the lower case 10a, the effect of suppressing dust leakage can be enhanced.

[0094] The connecting pipe 101 can connect 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 contacts the front lip 103b of the mouth packing 103. Thereby, airtightness between the internal passage of the extension pipe 20 and the inflow passage 103a of the mouth packing 103 can be ensured.

[0095] In this embodiment, since the flexible mouth packing 103 is provided between the connecting pipe 101 and the dust collection part 12, airtightness can be ensured between the suction passage 101a of the connecting pipe 101 and the inflow passage 103a of the mouth packing 103, between the internal passage of the extension pipe 20 and the inflow passage 103a of the mouth packing 103, and between the inflow passage 103a of the mouth packing 103 and the inlet 122a of the support plate 122 (dust collection filter 120).

[0096] According to this embodiment, since the dust collection part 12 and the connecting pipe 101 are integrally formed, the strength against the reaction force from the surface to be cleaned during cleaning can be ensured.

Embodiment

[0097] Embodiment 2 will be described with reference to FIGS. 17 and 18. FIG. 17 is a perspective view of the vacuum cleaner 1 according to Embodiment 2 of the present invention as seen obliquely from the front left. FIG. 18 is a left side view of the vacuum cleaner 1 according to Embodiment 4 of the present invention as seen from the left side. The components common to Embodiment 1 are denoted by the same reference numerals, and the detailed description thereof is omitted.

[0098] In the vacuum cleaner 1 described in the first embodiment, the electric blower 14 is driven by the electric power supplied from the battery pack 16. Therefore, when the charging capacity of the battery pack 16 decreases, it is necessary to perform charging. As shown in FIG. 17, a DC jack 19 for charging the battery pack 16 is provided on the main body central protrusion 10i that protrudes downward from the bottom of the vacuum cleaner 1 (the cleaner main body 10). The DC jack 19 is arranged facing forward of the vacuum cleaner 1. When placed on the stunt 50, a charging terminal is connected to the DC jack 19. Further, a fixing groove 10k extending in the front-rear direction is formed in the main body central protrusion 10i. The function of the fixing groove 10k will be described later.

[0099] In the vacuum cleaner 1, when replacing the dust collection filter 120, the cleaner main body 10 is placed on the floor surface Y. In the vacuum cleaner 1 of the present embodiment, in addition to the above-described main body central protrusion 10i (the second leg portion), a main body front protrusion 10h (the third leg portion) that protrudes downward from the bottom of the vacuum cleaner 1 and a main body rear protrusion 10j (the first leg portion) are provided. When the vacuum cleaner 1 is placed on the floor surface Y, the main body central protrusion 10i and the main body rear protrusion 10j come into contact with the floor surface Y. In a state where the vacuum cleaner 1 is placed on the floor surface Y, the main body front protrusion 10h floats from the floor surface Y, and the vacuum cleaner 1 is supported by the main body central protrusion 10i and the main body rear protrusion 10j.

[0100] When replacing the dust collection filter 120, the user will put a hand on the dust collection unit case 10c side. That is, when the user puts a hand on the dust collection unit case 10c side, a force is applied below the dust collection unit case 10c. Therefore, in the present embodiment, the main body front protrusion 10h is provided to receive the force applied to the dust collection unit case 10c when replacing the dust collection filter 120. When a force is applied to the dust collection unit 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 central protrusion 10i and the main body rear protrusion 10j.

[0101] In this embodiment, the rear protrusion 10j (first leg portion) of the main body is provided on the lower surface of the battery pack 16, the central protrusion 10i (second leg portion) of the main body is provided on the lower surface behind the dust collection portion 12, and the front protrusion 10h (third leg portion) of the main body is provided on the front lower surface of the dust collection portion 12. Note that the arrangement position is not limited to the position of this embodiment.

[0102] According to this embodiment, the front protrusion 10h, the central protrusion 10i, and the rear protrusion 10j of the main body that protrude downward from the bottom of the vacuum cleaner 1 (main body 10 of the vacuum cleaner) are provided, and these are arranged side by side in the front-rear direction of the vacuum cleaner 1 (main body 10 of the vacuum cleaner). Therefore, the dust collection filter 120 can be replaced with the vacuum cleaner 1 in a stable state.

Embodiment

[0103] Embodiment 3 will be described with reference to FIGS. 1, 19 to 22. In Embodiment 3, the configuration of the stand will be described. FIG. 19 is an external perspective view of the stand 50 according to Embodiment 3 of the present invention as viewed from the left front. FIG. 20 is a front view of the stand 50 according to Embodiment 3 of the present invention as viewed from the front. FIG. 21 is an upper external perspective view of the stand 50 according to Embodiment 3 of the present invention as viewed from the left front. FIG. 22 is an upper external perspective view of the stand 50 according to Embodiment 3 of the present invention as viewed from the right rear. FIG. 23 is an external perspective view of the dust collection filter storage box 54 as viewed from the left front. In FIGS. 19 to 22, the front-rear, left-right, and up-down directions are defined with the stand 50 as a reference. When the vacuum cleaner 1 is used as a reference, the up-down directions shown in FIGS. 19 to 22 coincide with the front-rear directions of the vacuum cleaner 1, and the front-rear directions shown in FIGS. 19 to 22 coincide with the up-down directions of the vacuum cleaner 1.

[0104] The stand 50 includes a base portion 51 placed on the floor surface, a support column 52 connected to the base portion 51 and extending upward from the base portion 51, and a holder portion 53 connected above the support column 52.

[0105] As shown in FIG. 1, the vacuum cleaner 1 is stored upright on the stand 50 with the front facing downward. The holder portion 53 includes a main body receiving portion 531 for receiving the main body 10 of the vacuum cleaner 1, a main body storage portion 532 for storing the lower portion of the main body 10 of the vacuum cleaner 1, and a projection receiving portion 533 for receiving the main body central projection 10i. The main body receiving portion 531 is formed in a curved shape so as to contact the decorative cover 10g of the main body 10 of the vacuum cleaner 1.

[0106] 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 on the main body central projection 10i when the vacuum cleaner 1 is stored in the stand 50 to fix the vacuum cleaner 1. Further, the projection receiving portion 533 is provided with a charging terminal 60 that connects to a DC jack 19 provided on the main body central projection 10i when the vacuum cleaner 1 is stored in the stand 50 to charge the battery pack 16. A wiring storage portion 521 is provided behind the support column 52, and a wiring fixing portion 537 is provided behind the holder portion 53, which stores the wiring electrically connected to the DC jack 19. The wiring storage portion 521 is formed behind the support column 52 so as to extend in the vertical direction.

[0107] The vacuum cleaner of this embodiment uses a disposable dust collection filter 120. The dust collection filter 120 is replaced when the dust is full and the suction force decreases. Therefore, it is necessary to prepare a replacement dust collection filter for the vacuum cleaner, and it has been a problem to secure a storage place for it. Therefore, in this embodiment, a storage place for the replacement dust collection filter 120 is secured in the holder portion 53 of the stand 50. In this embodiment, the stand 50 also functions as a charging stand provided with the charging terminal 60, but it is not limited to this, and it may not have the charging terminal 60.

[0108] On the left side surface (outer peripheral surface) of the holder portion 53, there is provided a dust collection filter storage box 54 that is rotatably supported so as to protrude from the storage space 535 to the outside of the holder portion 53. The dust collection filter storage box 54 includes a storage portion 541 that is open at the top and stores a plurality of dust collection filters 120, a front cutout portion 542 with a cutout in the front surface, a rotation shaft 543 provided respectively before and after the lower left side (outer lower side) of the dust collection filter storage box 54 for rotating the dust collection filter storage box 54, and a regulating projection 544 for stopping the rotating dust collection filter storage box 54 at a predetermined position. The regulating projection 544 is disposed inside the rotation shaft 543. Further, an inclined portion 544a that inclines downward and outward from above to below is formed on the regulating projection 544.

[0109] On the left side (outer peripheral side) of the holder portion 53, a rotation regulating portion 536 that abuts against the regulating projection 544 as shown in FIG. 22 is formed. In FIG. 22, only the rotation regulating portion 536 on the rear side of the holder portion 53 is illustrated, but the rotation regulating portion is similarly provided on the front side.

[0110] In the storage portion 541 of the present embodiment, three folded dust collection filters 120 are stacked in the front - rear direction and two - stage stacked in the vertical direction, for a total of six dust collection filters being stored. The outer peripheral side of the dust collection filter storage box 54 is higher in the vertical direction than the height of two - stage stacking of the dust collection filters 120 in the vertical 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 with six dust collection filters packaged. Therefore, in the present embodiment, the six packaged dust collection filters are directly accommodated in the storage portion 541. The remaining amount of the dust collection filter 120 can be confirmed through the front cutout portion 542.

[0111] When removing the dust collection filter 120 from the storage section 541, the dust collection filter storage box 54 is rotated about the rotation axis 543 as a fulcrum. The dust collection filter storage box 54 rotates such that the upper portion 54a protrudes outside the holder portion 53. By rotating, the dust collection filter storage box 54 can rotate between a removal position where the dust collection filter 120 can be removed and a storage position. The upper portion 54a of the dust collection filter storage box 54 is formed to be inclined so as to slope downward from the outer peripheral side toward the inner peripheral side. By configuring in this way, the rotation locus of the dust collection filter storage box 54 can be made small, and when the dust collection filter storage box 54 rotates, interference with the holder portion 53 can be suppressed.

[0112] When the dust collection filter storage box 54 rotates, the inclined portion 544a of the regulating projection 544 contacts the rotation regulating portion 536, and the rotation of the dust collection filter storage box 54 stops. At this time, it is preferable to position the center of gravity of the dust collection filter storage box 54 above the central portion in the vertical direction of the dust collection filter storage box 54. When the center of gravity of the dust collection filter storage box 54 is positioned upward, the dust collection filter storage box 54 can maintain an open state to the outside, and it becomes easier to remove the dust collection filter 120 from the storage section 541.

[0113] In particular, in the shape of the present embodiment, in a state where three dust collection filters 120 are stored in the dust collection filter storage box 54, the center of gravity positions of the dust collection filter storage box 54 and the dust collection filter 120 are closest to the holder portion 53. Even in this case, since the center of gravity is positioned outside the rotation axis, the dust collection filter storage box 54 can maintain an open state to the outside, and it has become easier to remove the dust collection filter 120 from the storage section 541.

[0114] When removing the dust collection filter 120 stored in the lower stage of the storage section 541, it can be taken out by passing a finger through the front notch portion 542 and pulling it upward.

[0115] Furthermore, in order to facilitate the removal of the dust collection filter 120 from the storage unit 541, the height H from the floor surface of the dust collection filter storage box 54 is preferably 70 cm or more. Thereby, since the storage box 54 is positioned around the user's hand, the dust collection filter 120 can be easily removed.

[0116] Also, the maximum protrusion amount when the dust collection filter storage box 54 opens outward is preferably set inside the extension line L of the base portion 51 so as not to protrude from the extension line L of the base portion 51. The stand 50 may be installed close to the wall. If the maximum protrusion amount of the dust collection filter storage box 54 is made not to protrude from the extension line L of the base portion 51, the dust collection filter 120 can be removed from the dust collection filter storage box 54 even when the stand 50 is installed close to the wall.

[0117] According to this embodiment, since the dust collection filter 120 is stored in the stand 50, the workability of replacing the dust collection filter 120 can be improved.

[0118] Note that, in this embodiment, the dust collection filter storage box 54 is configured to rotate the dust collection filter storage box 54 with the rotation shaft 543 as a fulcrum, but it is not limited to the rotation method, such as a method of moving the dust collection filter storage box 54 by sliding to a storage position and a take-out position for taking out the replacement dust collection filter 120.

[0119] The present invention is not limited to the above-described embodiments and includes various modifications. For example, the above-described embodiments have been described in detail for easy understanding of the present invention and are not necessarily limited to those having all the configurations described. Also, a part of the configuration of one embodiment can be replaced with the configuration of another embodiment, and the configuration of another embodiment can be added to the configuration of one embodiment. Also, for a part of the configuration of each embodiment, addition, deletion, or replacement with other configurations is possible.
