Description

[Technical Field]

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

[0002] A paper bag stick-type vacuum cleaner is an electric vacuum cleaner that the user grasps by a handle attached to the vacuum cleaner body to clean. A paper bag stick-type vacuum cleaner has an electric blower and a dust collection unit inside the vacuum cleaner body, and a dust collection filter is installed in the dust collection unit. Dust is sucked in through the suction nozzle via an extension tube connected to the vacuum cleaner body and collected in the dust collection filter.

[0003] In addition, a typical paper bag stick-type vacuum cleaner can also be used as a handheld vacuum cleaner by removing the extension tube connected to the vacuum cleaner body and sucking dust through the suction port of the vacuum cleaner body.

[0004] In paper bag vacuum cleaners, if dust leaks outside the dust collection filter, the dust can get into the electric blower, causing it to stop working or be damaged. As a countermeasure, a filter is often installed in front of the electric blower to prevent dust from getting in. Such an electric vacuum cleaner is disclosed in, for example, Patent Document 1. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-178936 Summary of the Invention [Problem to be solved by the invention]

[0006] The vacuum cleaner disclosed in Patent Document 1 has a structure in which a filter is placed between the dust bag and the electric blower to prevent dust from entering the motor. The filter is held in a filter frame that can slide up and down, making it easy to remove the inflated dust bag. Furthermore, the vacuum cleaner disclosed in Patent Document 1 prevents the filter frame from coming off when the filter frame is pulled out upward by abutting a convex portion of the filter frame against a grid-like rib provided at the opening in front of the electric blower.

[0007] However, in the vacuum cleaner disclosed in Patent Document 1, the filter frame has a retaining feature at the opening, so the sliding range of the filter frame is affected by the size of the opening. For example, if the same structure were to be adopted in a stick-type vacuum cleaner with a relatively small electric blower, the area of ​​the opening required in front of the electric blower would be smaller. As a result, the vertical sliding range of the filter frame would also be smaller, making it difficult to easily remove the dust bag.

[0008] An object of the present invention is to provide an electric vacuum cleaner that is not limited by the size of the electric blower, that suppresses dust from entering the electric blower, and that allows for easy removal of the dust collection filter. [Means for solving the problem]

[0009] In order to achieve the above object, the present invention provides an electric vacuum cleaner comprising: a vacuum cleaner body; an electric blower provided in the vacuum cleaner body; a dust collecting section provided in the vacuum cleaner body and having an opening for the electric blower that communicates with the electric blower; and a dust collecting filter that is detachably attached to the dust collecting section and collects dust sucked in by the suction force generated by the electric blower, wherein the dust collecting section is provided with a filter frame that can slide in a substantially vertical direction, and a protective filter that prevents dust from entering the electric blower is attached to the filter frame, the filter frame is positioned between the dust collecting filter and the opening for the electric blower, the filter frame is provided with a convex portion, and the dust collecting section is provided with a substantially rectangular recess in a position that does not overlap with the opening for the electric blower in the left-right direction, the convex portion is fitted into the recess, and the convex portion hits the upper end of the recess to prevent the filter frame from coming out. [Effects of the Invention]

[0010] According to the present invention, it is possible to provide an electric vacuum cleaner that prevents dust from entering the electric blower and allows the dust collection filter to be easily removed from inside the dust collection section. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In principle, identical elements are designated by the same reference numerals in all drawings. Furthermore, descriptions of parts having identical functions will be omitted. Note that the configurations described below are merely examples, and it is not intended that the embodiments of the present invention be limited to the specific embodiments below. [Example]

[0013] FIG. 1 is an external perspective view of a vacuum cleaner according to a first embodiment of the present invention, showing the cleaner 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 cleaner 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 cleaner used as a handheld 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, as indicated by arrows.

[0014] 1 and 2, the vacuum cleaner 1 comprises a vacuum cleaner body 10 forming an outer shell, an extension tube 20 having one end connected to the vacuum cleaner body 10 via a connecting tube 101, and a suction nozzle body 30 connected to the other end of the extension tube 20. The vacuum cleaner 1 of Example 1 is also provided with a brush part 40 on the outer periphery of the connecting tube 101. The connecting tube 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 tube 101, and this suction passage 101a communicates with the internal passage of the extension tube 20.

[0015] The extension tube 20 is connected to the vacuum cleaner main 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.

[0016] The vacuum cleaner body 10 has an outer shell formed by a lower case 10a and an upper case 10b disposed above the lower case 10a. The lower case 10a is composed of a pack chamber 10e housing a dust collection filter 120 and a motor chamber 10f (electric blower housing) housing an electric blower 14. The vacuum cleaner body 10 also includes a dust collection unit 12 that collects sucked dust, a dust collection lid 11 that opens and closes to cover the top of the dust collection unit 12, and a handle 13 that a user grasps when cleaning. The handle 13 is formed by a part of the upper case 10b, which also has an exhaust port. The dust collection lid 11 opens and closes around a pivot shaft 105 and is biased in the opening direction by a coil spring 110 (FIG. 8), which will be described later. The dust collection lid 11 also holds the dust collection unit 12 in a closed state by a dust collection lid clamp 112. The lower case 10a, which forms the underside of the dust collection section 12, is provided with a dust collection section gasket 127 (Figure 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, thereby maintaining an airtight seal inside the dust collection section 12.

[0017] By forming the dust collection cover 11 from a semi-transparent material, the bulge of the dust collection filter 120 can be confirmed, and the design can be further improved. A rib 10d is formed on the lower case 10a near the rear of the dust collection lid claw 11a that catches on the dust collection lid clamp 112. As a result, when the user lifts the electric vacuum cleaner 1 by holding the handle 13 in use as a stick type, the rib 10d presses down on the dust collection lid claw 11a, preventing the entire vacuum cleaner body 10 from bending and causing the dust collection lid claw 11a to come off the dust collection lid clamp 112.

[0018] 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 located behind the electric blower 14 and equipped with multiple storage batteries that supply power to the electric blower 14.

[0019] The handle portion 13 is provided with an operation switch 17 for turning the electric blower 14 on and off and adjusting the suction power.

[0020] 4, dust collecting unit 12 is detachably provided with a disposable dust collecting filter 120 that collects and filters dust sucked in through suction passage 101a. Dust collecting filter 120 is breathable and flexible, and is composed of a bag member 121 that collects dust, and a support plate 122 that has an inlet 122a formed in the center. Support plate 122 is inserted along a guide groove provided in dust collecting unit 12, and its upper part is fixed to dust collecting unit 12 by support plate clamp 104.

[0021] 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 .

[0022] With the central axis of suction passage 101a (central axis A of suction port 101b) horizontal, support plate 122 is attached to dust collection unit 12 at an angle so that its upper portion is located further rearward than its lower portion. 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 tilted by approximately 20° (different angles). In addition, port gasket 103 is provided between connecting pipe 101 and dust collection unit 12. Port gasket 103 is formed by inlet passage 103a (central axis C) communicating with suction passage 101a of connecting pipe 101 and rear lip 103c (central axis E) abutting against support plate 122. In addition, port gasket 103 is formed of a flexible material. For example, by using SBR as the flexible member and providing a mating surface between the mold on the inlet passage 103a side and the mold on the rear lip 103c side on the side of the check valve 103d, a thin plate portion can be formed on the side of the check valve 103d, and this thin plate portion acts as a thread rib, making it possible to reduce the gap between the check valve 103d and the inlet passage 103a. Reducing the gap between the check valve 103d and the inlet passage 103a prevents dust accumulated in the dust collection filter 120 from flowing back into the inlet passage 103a. A lip shape is formed at the tip of the front lip 103b of the mouth packing 103, and airtightness is maintained by abutting against the support plate 122.

[0023] Dust sucked in through suction port 101b of suction passage 101a passes through suction passage 101a and inflow passage 103a of mouth packing 103 together with air, and is collected in bag member 121 of dust collection filter 120 through inflow port 122a of support plate 122. The dust sucked into bag member 121 is filtered by bag member 121, and the air that passes through bag member 121 passes through protective filter 180 and electric blower opening 12b and is sucked into electric blower 14. Protective filter 180 is disposed between dust collection filter 120 and electric blower opening 12b to prevent dust leaking from bag member 121 from being sucked into electric blower 14. Protective filter 180 is supported by filter frame 18, which is slidable in a substantially vertical direction, and is attached to dust collection unit 12.

[0024] Electric blower 14 includes fan 141 that generates suction force, and electric motor 143 that is connected to fan 141 via rotary shaft 142 and drives fan 141 to rotate. Rotation center line D of rotary shaft 142 of electric blower 14 is arranged at an angle that slopes downward toward the downstream side (rear side).

[0025] A battery pack 16 that supplies power to the electric blower 14 is provided downstream (rear) of the electric blower 14.

[0026] When used as a stick-type vacuum cleaner, the suction body 30 is connected to the connecting tube 101 of the vacuum cleaner body 10 via the extension tube 20, as shown in Figure 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 unit 12.

[0027] When using the vacuum cleaner as a handheld electric vacuum cleaner, extension tube 20 is removed from connecting tube 101 of vacuum cleaner body 10, as shown in FIG. 3. By removing extension tube 20 from connecting tube 101, suction port 101b of suction passage 101a is exposed. The user grasps handle 13 and operates operation switch 17 to drive electric blower 14 and move connecting tube 101. Dust is then sucked directly through suction port 101b, and the sucked dust is collected in dust collection filter 120 of dust collection unit 12.

[0028] 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, making it difficult to clean dust on the floor. A configuration for solving this problem will be described using Figure 4.

[0029] 4, when the central axis of suction port 101b is A and the central position of the inlet of dust collecting filter 120 (the central position of inlet 122a of support plate 122) is B, in Example 1, central axis A of suction port 101b is positioned above central position B of the inlet of dust collecting filter 120 (the central position of inlet 122a of support plate 122). In other words, central axis A of suction port 101b is positioned closer to handle portion 13 than central position B of the inlet of dust collecting filter 120 (the central position of inlet 122a of support plate 122).

[0030] A mouth 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, sloping 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 center axis A of the suction port 101b.

[0031] 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), so that 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.

[0032] 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 irregularities, thereby improving the design.

[0033] 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 arranged so as to be offset from each other, so that 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 spills out from the inlet 122a, and the spilled dust is prevented from being discharged to the outside from the suction port 101b.

[0034] 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 unit 12, dust collected in dust collecting filter 120 can be prevented from spilling out from inlet 122a and being discharged to the outside from suction port 101b.

[0035] In the first embodiment, the user grips the handle portion 13 to operate the vacuum cleaner 1, and therefore a moment is applied to the user's hand. For this reason, it is preferable to reduce the moment applied to the user's 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 an extension line of the central axis A of the suction port 101b. In other words, the handle portion 13 of the first embodiment is configured to intersect with an extension line of the central axis A of the suction port 101b. With the above configuration 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.

[0036] In the electric vacuum cleaner 1, it is preferable to reduce ventilation loss in order to improve dust collection efficiency. Therefore, in the first embodiment, when the rotation center line of the rotation shaft 142 of the electric blower 14 is defined as D, the rotation center line D of the rotation shaft 142 of the electric blower 14 and the central axis E of the dust collecting filter 120 are configured to be parallel. With this configuration, ventilation loss from the dust collecting filter 120 to the electric blower 14 can be reduced, and dust collection efficiency can be improved. To further improve efficiency, the rotation center line D of the electric blower and the central axis E of the dust collecting filter 120 may be aligned in a straight line. In particular, in an electric vacuum cleaner equipped with a storage battery, improved dust collection efficiency can reduce the operating time of the electric blower 14, and the weight of the vacuum cleaner can be reduced by downsizing the storage battery.

[0037] Furthermore, in the electric vacuum cleaner 1, it is desirable to enlarge the dust collection section 12 to ensure a sufficient dust collection amount. However, it is preferable not to make the vacuum cleaner body 10 larger than necessary to prevent a decrease in operability. Therefore, in the first embodiment, the central axis C of the inlet passage 103a of the mouth gasket 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-to-rear direction can be reduced while ensuring the area of ​​the support plate 122. This allows the dust collection section 12 to be enlarged while reducing the length of the vacuum cleaner body 10.

[0038] Furthermore, it is desirable that the electric vacuum cleaner 1 be compact. The battery pack 16 housed in the vacuum cleaner main body 10 is larger in volume than the electric blower 14 in order to ensure battery capacity, which can easily lead to an increase in the size of the vacuum 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. This configuration can prevent the portion of the vacuum cleaner main body 10 that houses the battery pack 16 from expanding, thereby preventing the vacuum cleaner main body 10 from becoming larger. 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 is larger in volume than the electric blower 14, and therefore, in the first embodiment, the control board 15 is positioned taking into consideration the volumes of the electric blower 14 and the battery pack 16. This makes it possible to prevent the electric vacuum cleaner 1 from becoming too large.

[0039] It is also desirable that the vacuum cleaner 1 is lightweight. Weight can be reduced by providing irregularities 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 lightweight technology). It is desirable that the irregularities be thick in areas where strength is required and thin in areas where it is not, and the shape may be determined by simulation.

[0040] 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. [Example]

[0041] Next, a second embodiment will be described with reference to Figs. 5 and 6. In the second embodiment, the configurations of the dust collecting filter 120 and the dust collecting unit 12 will be described. Fig. 5 is an external perspective view of the dust collecting filter 120 according to the second 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 second embodiment of the present invention when being disposed of. The same reference numerals are used to designate components common to the first embodiment, and detailed descriptions thereof will be omitted.

[0042] 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, animal hair, plastic, or other nonwoven fabric, and a sealing 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 sealing member 123 is attached to one side of the quadrilateral support plate 122. Although the sealing member 123 is attached to the support plate 122 in the second embodiment, it may be attached by adhering it to a part of the bag member 121.

[0043] 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 catches on 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.

[0044] 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 the sealing member 123 is bonded to the upper side of the back surface of the support plate 122, it is preferable not to bond the sealing member 123 near 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 claws 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 claws of the support plate clamp 104.

[0045] Sealing member 123 includes sealing portion 124 having glue as an adhesive surface, and release paper 125 (release portion) covering the adhesive surface. Sealing portion 124 and release paper 125 are arranged with the glue as the boundary, with release paper 125 located on the front side of support plate 122 and sealing portion 124 located on the back side of support plate 122. Release paper 125 has a hooking hole 126 formed therein for hooking onto protrusion 104a provided on support plate clamp 104 of vacuum cleaner 1.

[0046] 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, with the exposed adhesive surface facing the front surface of support plate 122, and the adhesive surface of sealing portion 124 is attached to support plate 122. Inlet 122a of support plate 122 is covered and closed by sealing portion 124, so that spilling of dust from inlet 122a can be prevented even when dust collection filter 120 is disposed of, enabling hygienic handling.

[0047] It is preferable that the sealing portion 124 closes the inlet 122a of the support plate 122 when the dust collection filter 120 is removed from the dust collection unit 12 of the vacuum cleaner 1. The removal operation of the dust collection filter 120 will be described with reference to FIG.

[0048] Fig. 7 is a view showing a state in which the dust collecting filter 120 is being removed from the dust collecting unit 12 of the vacuum cleaner 1 according to the second 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.

[0049] When attaching dust collection filter 120 to dust collection unit 12 of vacuum cleaner 1, dust collection lid 11 is opened, support plate 122 of folded dust collection filter 120 (FIG. 5) is inserted into the guide portion so that it faces the outlet portion of mouth packing 103, and the upper portion of support plate 122 is hooked onto the claw portion of support plate clamp 104 and fixed in place. Also, hook hole 126 formed in release paper 125 is hooked onto protrusion 104a of support plate clamp 104. Thereafter, dust collection lid 11 is closed.

[0050] As shown in FIG. 8 , the dust collection lid 11 is biased in the opening direction by a coil spring 110. Two coil springs 110 are arranged side by side in the left-right direction. One lower tip 110a of the coil spring 110 is hooked onto the fixed part 106 of the vacuum cleaner 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. Furthermore, the upper tip 110b of the coil spring 110 on the dust collection lid 11 side is bent toward the dust collection part 12. As a result, 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 tip of the coil spring, making attachment easy.

[0051] An inner wall 12a of the dust collecting unit 12, which is separated from the electric blower 14, has a communication opening 151 that communicates with the space housing the control board 15. In the electric vacuum cleaner 1, the control software written in the control board 15 may need to be rewritten for maintenance or troubleshooting. In the second embodiment, a tool can be inserted through the communication opening 151 to rewrite the control software. The communication opening 151 is positioned outside the dust collecting unit packing 127, making it unrelated to the airtight structure of the dust collecting unit 12. During normal use, the communication opening 151 needs to be closed to prevent the user from touching the control board 15. Therefore, in the second embodiment, a label 152 is affixed to cover the communication opening 151. The label 152 indicates the model of the dust collecting filter 120 attached to the dust collecting unit 12. The user can purchase a replacement dust collecting filter 120 by checking the model number indicated on the label 152. Furthermore, since the user can easily confirm the model, it is possible to prevent the wrong model of dust collection filter 120 from being mistakenly attached. The affixed surface of label 152 is inclined so that the upper side is rearward relative to the lower side with respect to a line perpendicular to the rotation center line D of rotation shaft 142 of electric blower 14 (see FIG. 4). This makes it easy for the user to see the model printed on label 152. Similarly, the affixed surface of label 152 is inclined so that the upper side is rearward relative to the lower side with respect to a line perpendicular to parallel line F of control board 15 (see FIG. 4). This makes it easy to determine the position of the control software rewriting connector (not shown) on control board 15, improving workability. Therefore, the affixed surface of label 152 is not perpendicular to rotation center line D of rotation shaft 142 of electric blower 14 and parallel line F of control board 15.

[0052] 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 the user from accidentally putting their fingers into the electric blower 14 while ensuring an air inflow path.

[0053] When the electric blower 14 is driven and suction force is generated, the bag member 121 of the dust-collecting 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 supported by the filter frame 18. As shown in FIG. 9 , the filter frame 18 has a lattice portion 18a with a large opening in the front-to-rear direction, and the protective filter 180 is supported in contact with the front surface of the lattice portion 18a. This prevents the bag member 121 and the protective filter 180 from directly blocking the inlet of the electric blower 14, making it easier to maintain suction force. The filter frame 18 also has a top opening 18b and a side opening 18c. This makes it easier to maintain suction force by drawing air through the surrounding openings, even if the lattice portion 18a, which has an opening in the front-to-rear direction, is blocked by the bag member 121.

[0054] When electric blower 14 is driven and suction force is generated, dust collection lid 11 is bent inward due to negative pressure. On the inside of dust collection lid 11, there is provided contact portion 111 that comes into contact with lower case 10a of vacuum cleaner body 10 when dust collection lid 11 is bent. When electric blower 14 is driven, contact portion 111 comes into contact with lower case 10a, thereby preventing dust collection lid 11 from opening.

[0055] 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 (Figure 7).

[0056] The bag member 121 expands and sticks to the inner wall of the dust collecting unit 12, particularly to the filter frame 18 on the electric blower 14 side. However, in the configuration of Example 2, as shown in Figures 10(A) and 10(B), the filter frame 18 is slidable in a substantially vertical direction. Therefore, when the dust collecting filter 120 is pulled upward, the filter frame 18 also slides upward, making it easy to pull up the dust collecting filter 120. Furthermore, in Example 2, a raised shape 18d is provided on the upper part of the filter frame 18 (Figure 9). As a result, when the bag member 121 expands to the point where it sticks to the filter frame 18, the bag member 121 slips under the raised shape 18d. Therefore, when the dust collecting filter 120 is pulled out, the raised shape 18d is pushed upward, making it easier for the filter frame 18 to slide (Figures 10(A) and (B)).

[0057] The filter frame 18 has a protrusion 18e, and the inner wall 12a of the dust collecting unit 12 on the electric blower 14 side has a recess 12c, which is a substantially rectangular groove (FIG. 9). The recess 12c is larger in the vertical direction than the protrusion 18e, and the filter frame 18 is provided in the dust collecting unit 12 so 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 abuts on the upper end surface of the recess 12c to prevent it from coming out. The position of the recess 12c does not overlap with the electric blower opening 12b in the horizontal direction. This means that the size of the recess 12c in the vertical direction, and therefore the sliding range of the filter frame 18, is not easily affected by the size of the electric blower opening 12b. In Example 1, the recess 12c is provided on the electric blower 14 side of the inner wall 12a, but it may also be provided on the side of the inner wall 12a. For example, if the horizontal size of the electric blower opening 12b occupies most of the inner wall 12a on the electric blower 14 side, there will be a limit to the space available for providing the recess 12c in the inner wall 12a on the electric blower 14 side, but this problem can be avoided by providing the recess 12c in the inner wall 12a on the side surface.

[0058] Furthermore, because the hook holes 126 formed in the release paper 125 are hooked onto the protrusions 104a of the support plate clamp 104, when the dust collection filter 120 is pulled upward, the release paper 125 is turned up from the seal portion 124, and the seal portion 124 is further pulled and folded back toward the 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.

[0059] The dust collection filter 120 in the second embodiment is a disposable dust collection filter that is replaced when it becomes full of dust. Therefore, it is necessary to have replacement dust collection filters on hand, but there is a risk that a user may forget to buy one. Therefore, a sensor that detects when 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 depending on the number of times the dust collection filter 120 has been replaced. For example, a home server may be installed and 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 retailer. [Example]

[0060] A third embodiment will be described with reference to Figs. 11 to 15. In the third embodiment, the configuration of the dust collecting unit 12 will be described. Fig. 11 is an exploded perspective view of the vacuum cleaner 1 in which the connecting pipe 101 and the dust collecting unit 12 according to the third embodiment of the present invention are disassembled. Fig. 12 is an exploded perspective view of the connecting pipe 101 according to the third embodiment of the present invention with the button cover 102 removed. Fig. 13 is a perspective view of the connecting pipe 101 in the state shown in Fig. 12 with the button cover 102 attached thereto. Fig. 14 is a perspective view of the port packing 103 according to the third embodiment of the present invention as seen from the front. Fig. 15 is a perspective view of the port packing 103 according to the third embodiment of the present invention as seen from the rear. Configurations common to the first and second embodiments are designated by the same reference numerals, and detailed descriptions thereof will be omitted.

[0061] A port packing 103 is attached to the front of the dust collecting unit 12 from the inside of the dust collecting unit 12, and a connecting pipe 101 is attached to the outside (front side) of the dust collecting unit 12. The end of the connecting pipe 101 comes into contact with a front lip 103b of the port packing 103. Because 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.

[0062] A dust collection unit gasket 127 is disposed on the upper opening edge of the lower case 10a, which forms the underside of the dust collection unit 12, to come into contact with the dust collection lid 11 when the dust collection lid 11 is closed to keep the dust collection unit 12 airtight. The front of the dust collection unit gasket 127 is disposed between the support plate clamp 104 and the dust collection lid clamp 112, and the rear of the dust collection unit gasket 127 is disposed behind the filter frame 18. A gasket fixing portion 127a is formed at the front end of the dust collection unit gasket 127 (FIGS. 11 and 12).

[0063] A button cover 102 is disposed above the connecting pipe 101, covering the lock button 102a and the upper part of the dust collection lid clamp 112. When the dust collection lid clamp 112 is disposed above the connecting pipe 101, the dust collection lid clamp 112 covers a packing fixing portion 127a at the front end of the dust collection unit packing 127. As a result, the packing fixing portion 127a is sandwiched between the lower case 10a and the button cover 102 from above and below, and the front of the dust collection unit packing 127 is fixed to the lower case 10a (FIG. 13).

[0064] In this embodiment, the dust collection lid 11 has a claw portion facing forward and is hooked by the dust collection lid clamp 112. However, the dust collection lid 11 may have a claw portion facing backward and a claw receiver 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 this case, the dust collection lid clamp 112 can be omitted.

[0065] A lead wire (not shown) that supplies power to the suction nozzle is wired between the dust collection unit packing 127 and the lower case 10a. By attaching the dust collection unit packing 127 to the lower case 10a side, the lead wire is not visible to the user, ensuring a stylish design.

[0066] Furthermore, 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 for the front inlet and the rear motor inlet, while the lowered left and right sides widen 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.

[0067] As shown in Figures 14 and 15, the mouth gasket 103 includes 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 part 103e that connects the check valve 103d to the rear lip 103c.

[0068] 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.

[0069] The check valve 103d operates to open downstream (rearward) with the check valve connection portion 103e as a fulcrum. By making the check valve connection portion 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 move toward the rear lip 103c than if the check valve connection portion 103e and the check valve 103d were on the same plane. Furthermore, a pair of intra-passage protrusions 103f are provided on the left and right sides of the inflow passage 103a of the mouth packing 103, protruding toward the side away from the inflow passage 103a. Furthermore, an intra-passage protrusion 103f is also provided in a position diagonal to the check valve connection portion 103e in the inflow passage 103a. The intra-passage protrusions 103f prevent the check valve 103d from opening upstream (forward). This prevents dust collected in the bag member 121 of the dust collecting filter 120 from leaking out. 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 vibration of the check valve 103d. Furthermore, by arranging an intra-passage protrusion 103f at the position where the check valve rib 103g is located, it is possible to prevent the check valve 103d from bending toward the front lip 103b due to the weight of dust. The intra-passage protrusion 103f is bent toward the front lip 103b in an L-shape, so that when the port packing 103 is pulled toward the rear lip 103c, the port packing 103 gets caught on the intra-passage protrusion 103f, making it difficult for the port packing 103 to come off. The end face of the intra-passage protrusion 103f on the front lip 103b side is chamfered, which reduces flow path loss during suction and reduces the likelihood of the sucked dust getting caught on the intra-passage protrusion 103f. The rear lip 103c has an outer lip 103j and an inner lip 103i. When the dust collecting filter 120 is attached, each lip flexes, ensuring 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 collecting filter 120 is attached smaller than the outer diameter of the inlet 122a of the dust collecting filter 120, it is possible to reduce flow path loss and dust getting caught in the support plate 122. The mouth packing 103 has a spill prevention rib 103h on the inside of the inner lip 103i.By making the outer diameter of spill prevention rib 103h smaller than the outer diameter of inlet 122a of dust collection filter 120, when suction port 101b is facing downward, dust accumulated on dust collection filter 120 is caught by spill prevention rib 103h, reducing the backflow of dust toward suction passage 103a. Note that intra-passage protrusion 103f may be provided on lower case 10a, and a through-hole may be provided in port packing 103. In this case, intra-passage protrusion 103f can be formed from the hard material of lower case 10a, thereby improving the effect of suppressing dust leakage.

[0070] The connecting pipe 101 can be connected to an extension pipe 20. To connect the extension pipe 20 to the connecting pipe 101, the extension pipe 20 is inserted into the connecting pipe 101. When the extension pipe 20 is inserted into 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.

[0071] 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). [Example]

[0072] Example 4 will be described with reference to Figures 16 and 17. Figure 16 is a bottom view of the electric vacuum cleaner 1 according to Example 4 of the present invention as seen from below. Figure 17 is a left side view of the electric vacuum cleaner 1 according to Example 4 of the present invention as seen from the left. The same reference numerals are used to designate components common to Examples 1 to 3, and detailed descriptions thereof will be omitted.

[0073] The electric vacuum cleaner 1 described in Examples 1 to 3 drives the electric blower 14 with power supplied from the battery pack 16. Therefore, when the charge capacity of the battery pack 16 decreases, it is necessary to charge it. As shown in Fig. 16, a DC jack 19 for charging the battery pack 16 is provided at the bottom of the electric vacuum cleaner 1.

[0074] A charging terminal 60 is connected to the DC jack 19 when charging the battery pack 16. When the charging terminal 60 is inserted into the DC jack 19, the charging terminal 60 protrudes from the bottom surface (outer periphery) of the vacuum cleaner body 10. If the vacuum cleaner 1 is placed on floor Y with the charging terminal 60 connected to the DC jack 19, the charging terminal 60 may come into contact with the floor Y, which may damage the charging terminal 60 or scratch the floor Y.

[0075] Therefore, in the electric vacuum cleaner 1 of this embodiment, a lower body protrusion 10c that protrudes downward is provided at the bottom of the lower case 10a of the vacuum cleaner body 10.

[0076] When the lowest rear end of the vacuum cleaner 1 (battery pack 16) is connected in a straight line to the main body lower protrusion 10c, a space is formed between the lowest rear end of the vacuum cleaner 1 (battery pack 16) and the main body lower protrusion 10c. In other words, when the vacuum cleaner 1 is placed on floor surface Y, a space is formed between the lowest rear end of the vacuum cleaner 1 (battery pack 16) and the main body lower protrusion 10c, away from the floor surface Y. When the DC jack 19 is placed in this space, the charging terminal 60 will not come into contact with the floor surface Y even when connected to the DC jack 19.

[0077] According to the fourth embodiment, even when the charging terminal 60 is connected to the DC jack 19 and the battery pack 16 is being charged, the charging terminal 60 does not come into contact with the floor surface Y, thereby preventing damage to the charging terminal 60 and scratches on the floor surface Y. [Example]

[0078] Fig. 18 is an exploded perspective view of the vacuum cleaner 1 according to the fifth embodiment of the present invention, with the connecting pipe 101, the lower case 10a, and the upper case 10b disassembled. Fig. 19 is a perspective view of the pack chamber 10e according to the fifth embodiment of the present invention, with the dust collection section gasket 127 removed. The same reference numerals are used for the components common to the first to fourth embodiments, and detailed descriptions thereof will be omitted.

[0079] The vacuum cleaner body 10 includes a dust collection unit 12 that collects sucked dust, a dust collection lid 11 that forms the upper part of the dust collection unit 12 and can be opened and closed to cover it, and a pack chamber 10e that forms the lower part of the dust collection unit 12. The dust collection lid 11 opens and closes around a pivot shaft 105, and a dust collection lid clamp 112 (locking mechanism) holds the dust collection unit 12 in a closed state. The pack chamber 10e includes a dust collection unit gasket 127 (airtightness maintaining member). When the dust collection lid 11 is closed, the dust collection lid 11 comes into contact with the dust collection unit gasket 127 to maintain airtightness within the dust collection unit 12. The pack chamber 10e is made of a flexible material, which minimizes factors that could cause air leakage and makes it easier to maintain airtightness. In this embodiment, the dust collection unit gasket 127 is made of a flexible material, but it is not limited to a flexible material as long as it can maintain airtightness within the dust collection unit 12 by contacting the dust collection lid 11.

[0080] If the contact between dust collection lid 11 and dust collection unit gasket 127 becomes misaligned, it will be impossible to maintain airtightness inside dust collection unit 12. However, if dust collection lid 11 and dust collection lid clamp 112 were provided as separate parts from pack chamber 10e, tolerances would become too large and airtightness could no longer be maintained. Therefore, in the vacuum cleaner 1 of this embodiment, the fixing parts of dust collection lid 11 and dust collection lid clamp 112 are each provided in pack chamber 10e, and the mounting structure for the parts necessary to ensure airtightness of dust collection unit 12 is concentrated in pack chamber 10e. This minimizes tolerances in the airtight space, making it easier to maintain airtightness.

[0081] The rear of the pack chamber 10e is provided with a vibration-isolating rubber 144 (vibration absorbing member). The vibration-isolating rubber 144 fixes at least a part of the electric blower 14, ensuring airtightness from the dust collecting section 12 to the electric blower 14 and absorbing vibrations of the electric blower 14.

[0082] In the electric vacuum cleaner 1 described in Examples 1 to 4, a suction motor (not shown) provided in the suction body 30 is driven by power supplied from the battery pack 16, which rotates a rotating brush (not shown) provided in the suction body. Therefore, power must be supplied from a control board 15 housed in a motor chamber 10f (electric blower housing) through a connection pipe 101 and an extension pipe 20. The conductive parts must be hidden from the standpoint of safety and design. A conductive part 108 is disposed in the pack chamber 10e between a side wall 107a that contacts the dust collection unit gasket 127 and the outer shell of the pack chamber 10e. A wiring opening 153 that communicates with the space housing the control board 15 is formed in the inner wall 12a of the dust collection unit 12, which is separated from the electric blower 14. By routing the wiring from the wiring opening 153 through the conductive part 108, the wiring and the wiring opening 153 can be hidden by the dust collection unit gasket 127, ensuring safety and design. By locating wiring opening 153 outside dust collection unit packing 127, it is possible to ensure airtightness without having a configuration that is unrelated to the airtight configuration of dust collection unit 12. It is also desirable for vacuum cleaner 1 to be small. By not providing any parts to hide the wiring, but instead hiding it with dust collection unit packing 127, which is essential to dust collection unit 12, and the outer shell of dust collection unit 12, the number of parts is reduced, making it smaller and lighter.

[0083] Dust collection section packing 127 is fixed by being sandwiched between side wall 107a and packing fixing rib 107b. Generally, ribs need to stand flat to prevent molding defects such as sink marks, but providing side wall 107a and packing fixing rib 107b on dust collection lid 11 could significantly impair the design of vacuum cleaner 1. Therefore, in vacuum cleaner 1 of this embodiment, pack chamber flat surface 109 is provided in pack chamber 10e, and side wall 107a and packing fixing rib 107b are provided on pack chamber flat surface 109, thereby achieving a structure that does not impair the design. [Example]

[0084] A sixth embodiment will be described with reference to FIGS. 20 to 23. In the sixth embodiment, another method of attaching a dust collecting filter to a dust collecting unit will be described. FIG. 20 is a perspective view of a vacuum cleaner 1 (a dust collecting filter type vacuum cleaner) according to a sixth embodiment of the present invention. (a) shows the vacuum cleaner main body, and (b) shows the vacuum cleaner stored in a stand 50. FIG. 21 is a perspective view of a dust collecting filter case 500 according to the sixth embodiment of the present invention. (a) shows the dust collecting filter case stored in the dust collecting unit 12, and (b) shows the components after sliding and rotating to pull the dust collecting filter case out of the dust collecting chamber. FIG. 22 is a cross-sectional view taken along the line AA in FIG. 20. (a) shows the state before the dust collecting filter mounting portion of the dust collecting filter case is stored in the dust collecting chamber, and (b) shows the state after the dust collecting filter mounting portion is stored in the dust collecting chamber. FIG. 23 is a diagram showing a series of operations for removing a dust collecting filter according to the sixth embodiment of the present invention. (a) shows the state in which the dust collection lid 11 is closed, which is the state during normal cleaning, (b) shows the state in which the dust collection lid 11 is open, (c) shows the state in which the dust collection filter case has been pulled out, (d) shows the state in which the dust collection filter mounting part has been rotated so that the opening of the dust collection filter faces forward instead of downward, and (e) shows the state in which the dust collection filter has been removed from the dust collection filter case.

[0085] In this embodiment, the dust collecting section 12 further includes a dust collecting filter case 500 for fixing and positioning the dust collecting filter 120 as shown in FIG.

[0086] The dust collecting filter case 500 includes a first guide portion 501 provided on the lower case 10a, a second guide portion 502 provided on the first guide portion 501, and a dust collecting filter attachment portion 503 provided on the second guide portion 502. The first guide portion 501, the second guide portion 502, and the dust collecting filter attachment portion 503 are each provided to be slidable in the vertical direction. The dust collecting filter attachment portion 503 is also attached to the second guide portion 502 so that it can rotate about a rotation axis H. With this configuration, when replacing the dust collecting filter 120, the dust collecting filter attachment portion 503 can be pulled out of the dust collecting unit 12, and then the orientation of the opening 503a of the dust collecting filter attachment portion 503 can be changed. As a result, even if the inlet 122a of the dust collection filter 120 in the dust collection unit 12 is facing downward from the horizontal direction when cleaning the floor or storing it in the stand 50, when the dust collection filter 120 is removed from the dust collection filter mounting unit 503, the inlet 122a of the dust collection filter 120 can be made to face upward from the horizontal direction, thereby preventing dust from spilling out.

[0087] Here, the direction in which the dust collection filter case is pulled out to the outside of the dust collection chamber is not limited to the upward direction as in this embodiment, and the sliding direction of each part constituting the dust collection filter case is not limited to the vertical direction. For example, the dust collection filter case may be structured to be pulled out in the left-right direction.

[0088] Furthermore, in this embodiment, the operation of pulling out the dust collection filter case is a two-step process in which the dust collection filter is pulled out of the dust collection chamber by linear sliding, and then the dust collection filter mounting part is rotated to change the orientation of the dust collection filter, but the sliding trajectory is not limited to a linear one, and the process is not limited to two steps.

[0089] For example, the dust filter may slide along a substantially circular or elliptical path, and the orientation of the dust filter may change simultaneously with the sliding.

[0090] Dust collection filter mounting portion 503 has opening 504 so as not to block inlet 122a of dust collection filter 120. Dust collection filter mounting portion 503 is also fitted with dust spill prevention lid 506 sandwiching compression spring 505, and dust spill prevention lid 506 closes opening 504 of dust collection filter mounting portion 503 by the elastic force of compression spring 505 unless an external force is applied.

[0091] Here, the means by which dust spill prevention cover 506 closes opening 504 of dust collection filter attachment portion 503 is not limited to the means using compression spring 505 as in this embodiment. For example, other types of springs such as tension springs or torsion springs may be used, or a mechanism that does not use elastic force, such as a link mechanism, may also be used.

[0092] Dust spill prevention lid 506 is provided with receiving rib 507. As a result, when dust collection filter case 500 is stored in the dust collection chamber, it comes into contact with push-out protrusion 508 provided on the vacuum cleaner body, and only dust spill prevention lid 506 is pushed aside in the direction that opens opening 504 of dust collection filter attachment part 503.

[0093] With the above configuration, opening 504 is open when dust collection filter attachment portion 503 is inside the dust collection chamber, and opening 504 is closed by dust spill prevention cover 506 in other states, thereby preventing dust from spilling out.

[0094] 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 to clearly explain the present invention, and the present invention is not necessarily limited to those including all of the described configurations. Furthermore, it is possible to replace part of the configuration of one embodiment with the configuration of another embodiment, or to add the configuration of another embodiment to the configuration of one embodiment. Furthermore, it is possible to add, delete, or replace part of the configuration of each embodiment with other configurations. [Explanation of symbols]
