Description

Technical Field

[0001] The present disclosure relates generally to a vacuum cleaner, and more particularly to a filter and a filter housing for a vacuum cleaner. Background Art

[0002] The vacuum cleaner is configured to remove debris from a surface to be cleaned (e.g., a floor) using suction. For example, the vacuum cleaner may include an air inlet, an air outlet, a dust cup, and a suction motor. The suction motor is configured to draw air from the air inlet into the dust cup. At least a portion of any debris entrained in the air flowing into the dust cup is deposited in the dust cup for later processing. The suction motor is configured to make air flow from the dust cup to the air outlet. The air flowing from the air outlet is returned to the surrounding environment. Therefore, in some cases, a filter may be placed in the air path at a position between the suction motor and the air outlet. The filter may be configured to capture at least a portion of any remaining debris entrained in the air before the air enters the surrounding environment. Over time, the performance of the filter may be reduced due to the collection of debris. Therefore, the filter may be replaced or cleaned to restore the performance of the filter.

[0035] The present disclosure generally relates to a vacuum cleaner. The vacuum cleaner includes: a suction motor; a filter chamber fluidly coupled to the suction motor, the filter chamber configured to receive a filter; and a filter cover selectively surrounding the filter chamber. The filter cover is configured to switch from a closed position to an open position in response to actuation of a release. The release includes a rotatable portion and a sliding portion, the sliding portion configured to slide in response to rotation of the rotating portion.

[0036] Figure 11 is an illustrative example of a vacuum cleaner 100. The vacuum cleaner 100 includes: a main body 102; an air inlet 104; an air outlet 106; a dust cup 108, which is coupled (e.g., detachably and / or pivotably coupled) to the main body 102; and a suction motor 110, which is coupled to the main body 102 and is configured to allow air to flow into the air inlet 104 through the dust cup 108 and out of the air outlet 106. A post-motor filter 112 may be disposed downstream of the suction motor 110 and upstream of the air outlet 106. In other words, the post-motor filter 112 may be disposed at a position between the suction motor 110 and the air outlet 106 along an air path 114 extending through the main body 102.

[0037] The body 102 defines a filter chamber 116 that is fluidly coupled to the suction motor 110. The post-motor filter 112 is removably disposed within the filter chamber 116. The filter chamber 116 has an open end 118 through which the post-motor filter 112 can be inserted into or removed from the filter chamber 116. The filter cover 120 can be coupled (e.g., removably or pivotably) to the body 102 so that the filter cover 120 extends over at least a portion of the filter chamber 116 and / or the post-motor filter 112 (e.g., to selectively surround at least a portion of the open end 118 of the filter chamber 116). For example, the filter cover 120 can be configured to transition between an open position and a closed position, wherein when the filter cover 120 is in the open position, the post-motor filter 112 can be removed from the filter chamber 116.

[0038] The release member 122 is configured to switch between a release position and a holding position to selectively hold the filter cover 120 in the closed position. When the release member 122 is in the holding position, the release member holds the filter cover 120 in the closed position. When the release member 122 is in the release position, the filter cover 120 can be switched to the open position.

[0039] The release member 122 includes a body release portion 124 movably coupled to the body 102 and a cover release portion 126 movably coupled to the filter cover 120. The body release portion 124 is configured to cooperate with the cover release portion 126 to selectively hold the filter cover 120 in the closed position. For example, at least a portion of the body release portion 124 can be rotatably coupled to the body 102, and at least a portion of the cover release portion 126 can be slidably coupled to the filter cover 120. In this example, the rotational movement of the body release portion 124 causes a corresponding linear movement of the cover release portion 126. The linear movement of the cover release portion 126 causes the release member 122 to switch between the holding position and the release position.

[0040] In some cases, filter cover 120 can include one or more vents 128 that define at least a portion of air outlet 106. Thus, air exiting post-motor filter 112 passes through at least one of the one or more vents 128 and into the surrounding environment. Post-motor filter 112 can be a pleated filter, a foam filter, and / or any other filter media. In some cases, post-motor filter 112 can be a high efficiency particulate air (HEPA) filter.

[0041] Figure 2 A perspective view of a vacuum cleaner 200 is shown. Figure 1 1. An example of a vacuum cleaner 100 of the present invention. As shown, the vacuum cleaner 200 includes: a nozzle 202, the nozzle defining an air inlet 204; a dust cup 206, the dust cup fluidly coupled to the nozzle 202; a suction motor 208 (schematically shown in dashed lines); and a filter cover 210, the filter cover including one or more vents 212 defining at least a portion of an air outlet 214. In some cases, the vacuum cleaner 200 can be powered by a battery 216. The battery 216 can be coupled to a handle 218. For example, and as shown, the battery 216 can be coupled to a first distal end 220 of the handle 218, wherein the first distal end 220 is opposite to a second distal end 222 of the handle 218 and the second distal end 222 is closer to the dust cup 206 than the first distal end 220.

[0042] Figure 3 Show Figure 2 2 is a perspective exploded view of a portion of a vacuum cleaner 200. As shown, the vacuum cleaner 200 includes: a body 300, the body defining a filter cavity 302, the filter cavity being configured to removably receive a filter 304 (e.g., a post-motor filter); and a release 306 for selectively coupling the filter cover 210 to the body 300. For example, the release 306 can be configured to transition between a release position (e.g., the filter cover 210 can be removed from the body 300) and a retaining position (e.g., the release 306 is configured to prevent the filter cover 210 from being removed from the body 300). As shown, the filter cover 210 is configured to at least partially surround the filter cavity 302, thereby retaining the filter 304 within the filter cavity 302. The body 300 can be a one-piece or multi-piece body.

[0043] The release member 306 includes a body release portion 308 and a cover release portion 310. As shown, the body release portion 308 includes a protrusion 312 and a rotating ring 314. The protrusion 312 is configured to rotate with the rotating ring 314. The rotating ring 314 is configured to rotate around the actuation rotation axis 316. The cover release portion 310 includes a latch 318, which is configured to move linearly along a latch axis 320. The latch axis 320 can extend substantially (e.g., 1%, 2%, 3%, 4%, or 5%) parallel to the actuation rotation axis 316. The latch 318 is configured to selectively engage one or more latch buckles 322 of the body 300 (e.g., formed by the body 300 or coupled to the body 300) to selectively couple the filter cover 210 to the body 300. The latch 318 is configured to switch between a locked position and an unlocked position in response to the rotational movement of the rotating ring 314 around the actuation rotation axis 316. For example, the protrusion 312 may be configured to engage (eg, contact) the latch 318 such that rotational movement of the protrusion (due to rotation of the rotating ring 314 ) transitions the latch 318 between the locked position and the unlocked position.

[0044] As shown, the latch 318 is biased toward the unlocked position (or out of engagement with one or more latch catches 322) using a biasing mechanism 324 (e.g., a spring). Thus, in these cases, the protrusion 312 is configured to engage the latch 318 when the release member 306 is in the retaining position, and is configured to substantially not engage the latch 318 when the release member 306 is in the releasing position. In other words, the engagement between the protrusion 312 and the latch 318 prevents the latch 318 from disengaging from the one or more latch catches 322 due to the biasing force of the biasing mechanism 324.

[0045] Figure 4 An exploded perspective view of the filter cover 210 is shown. As shown, the filter cover 210 includes a latch cavity 400 and a cover 402 configured to surround the latch cavity 400. The latch cavity 400 is configured to movably receive at least a portion of the latch 318. For example, the latch 318 can be slidable within the latch cavity 400 in response to rotation of at least a portion of the body release portion 308 (e.g., the rotating ring 314).

[0046] As shown, the latch 318 includes an actuated portion 406 configured to engage with a body release portion 308 (e.g., a protrusion 312) ( Figure 4A ) engagement; and an actuating portion 408, the actuating portion being configured to selectively engage with the body 300 (eg, one or more latch catches 322) ( Figure 4B) engagement. The actuation portion 408 may include a base region 410, a first leg 412 extending from the base region 410, and a second leg 414 extending from the base region 410. The first leg 412 is spaced apart from the second leg 414 along a separation axis 416 extending transversely to (e.g., perpendicular to) the latch axis 320 to form a biasing mechanism region 418, which is configured to receive at least a portion of the biasing mechanism 324. As also shown, the actuation portion 406 extends from the base region 410 of the actuation portion 408 in a direction opposite to the first leg 412 and the second leg 414. Thus, in some cases, the latch 318 may be described as generally having a Y-shape. In some cases, the first tab 413 may extend from the first leg 412 and the second tab 415 may extend from the second leg 414. The first tab 413 and the second tab 415 may be configured to selectively engage the corresponding latch buckle 322 ( Figure 3 ). As shown, filter cover 210 has a generally arcuate shape, and in some cases, latch 318 can have a corresponding arcuate shape.

[0047] The base region 410 can include one or more angled shoulders 420 that are angled in a direction extending generally along the separation axis 416 (or generally away from the latch axis 320). For example, the base region 410 can include a plurality of angled shoulders 420, wherein each angled shoulder 420 extends over at least a portion of a corresponding one of the first leg 412 or the second leg 414. The one or more angled shoulders 420 can be configured to facilitate sliding of the latch 318 within the latch cavity 400 (e.g., by reducing the risk of binding).

[0048] As shown, the latch cavity 400 can have a first latch cavity width 422 and a second latch cavity width 424, the first latch cavity width 422 being less than the second latch cavity width 424. For example, the second latch cavity width 424 can be at least two times greater than the first latch cavity width 422. The first latch cavity width 422 can generally correspond to the maximum width of the actuated portion 406 of the latch 318, and the second latch cavity width 424 can generally correspond to the maximum width of the actuated portion 408 of the latch 318. In some cases, the latch cavity 400 can have one or more cavity inclined regions 426 that correspond to a corresponding one of the one or more inclined shoulders 420.

[0049] Figure 5A cross-sectional view of the filter cover 210 is shown with the cover 402 removed therefrom for clarity. As shown, a second tab 415 extends from the second leg 414 (the first tab 413 may be similar to the second tab 415). The second tab 415 includes a tab top surface 502 that is offset from the leg top surface 504 of the second leg 414 by an offset distance 506. The offset distance 506 may be, for example, at least one-third, at least one-quarter, or at least one-eighth of the maximum leg thickness 508.

[0050] The second tab 415 is configured to extend at least partially from the latch cavity 400 to engage the corresponding latch catch 322 ( Figure 3 ). For example, at least a portion of the second tab 415 can extend through a cavity opening 510 that extends within one or more side walls 512 that define the latch cavity 400. The biasing mechanism 324 can bias the latch 318 in a direction that urges the first tab 413 and the second tab 415 to not engage with the corresponding latch catch 322. The first tab 413 can have a substantially similar configuration as the second tab 415.

[0051] Figure 6 314. As shown, the rotating ring 314 has an inner diameter 600 and an outer diameter 602 and defines an open area 604. The open area 604 can be configured to receive at least a portion of the body 300 ( Figure 3 ). As also shown, the protrusion 312 can include one or more protrusion inclined regions 606 such that the protrusion length 608 is non-constant along at least a portion of the protrusion width 610. The rotating ring 314 can also include one or more rotating guides 612 configured to guide the rotating ring 314 to rotate about the actuation rotation axis 316. For example, the one or more rotating guides 612 can be received in a corresponding track 614 ( Fig. 6A ). Track 614 may include a pawl 616 configured to resist (but not prevent) initial rotation of rotating ring 314. This configuration may prevent accidental rotation of rotating ring 314. In some cases, one or more rotating guides 612 may be configured to engage a biasing mechanism.

[0052] Figure 7 A perspective view of filter 304 is shown. As shown, filter 304 includes filter media 700 (e.g., pleated filter media) coupled to filter frame 702. Filter media 700 may be HEPA filter media. In some cases, and as shown, filter 304 may have an arcuate shape.

[0053] The filter medium 700 has a dirty air side 704 and a clean air side 706 opposite the dirty air side 704. The filter frame 702 includes a first end cap 708, a second end cap 710, and a filter support 712 extending between the first end cap 708 and the second end cap 710. The filter support 712 extends along the dirty air side 704 of the filter medium 700 and includes one or more air passages 714. The filter support 712 may also include one or more retaining protrusions 716 and at least one spring-loaded retainer 718. The one or more retaining protrusions 716 are configured to be received in the body 300 ( Figure 3 ) in a corresponding container, and at least one spring-loaded retainer 718 can be configured to push one or more retaining protrusions 716 into the corresponding container.

[0054] Figure 8 An exploded view of filter 304 is shown. As shown, each of first end cap 708 and second end cap 710 defines a filter cavity 800 and 802 for receiving a portion of filter media 700. In some cases, filter media 700 can be adhesively coupled to end caps 708 and 710 using a cap adhesive 801 disposed within filter cavities 800 and 802. For example, cap adhesive 801 disposed within end caps 708 and 710 can be a two-part adhesive, such as an epoxy resin mixed with a multifunctional hardener.

[0055] The filter support 712 includes a first coupling surface 804 and a second coupling surface 806 on opposite sides of the filter support 712. At least a portion of the first coupling surface 804 and the second coupling surface 806 extend between at least a portion of the first end cap 708 and the second end cap 710. The first coupling surface 804 and the second coupling surface 806 of the filter support 712 can be adhesively coupled to the filter medium 700 using a support adhesive 803. For example, the support adhesive 803 that couples the filter medium 700 to the first coupling surface 804 and the second coupling surface 806 can be a hot melt adhesive.

[0056] In some cases, the cap adhesive 801 that couples the filter media 700 to the end caps 708 and 710 can be different from the support adhesive 803 that couples the filter media 700 to the filter support 712. For example, the cap adhesive 801 that couples the filter media 700 to the end caps 708 and 710 can be a two-part adhesive, such as an epoxy mixed with a multifunctional hardener, and the support adhesive 803 that couples the filter media 700 to the filter support 712 can be a hot melt adhesive.

[0057] As also shown, the second end cap 710 (the first end cap 708 may have a similar configuration) has a mounting sidewall 808, a first support member sidewall 810 extending from the mounting sidewall 808, and a second support member sidewall 812 extending from the mounting sidewall 808. The first support member sidewall 810 extends along the dirty air side 704 of the filter medium 700, and the second support member sidewall 812 extends along the clean air side 706 of the filter medium 700. The filter medium 700 extends from the first support member sidewall 810 to the second support member sidewall 812. In some cases, the filter medium 700 may directly contact both the first support member sidewall 810 and the second support member sidewall 812. The cap adhesive 801 may be disposed between the filter medium 700 and the mounting sidewall 808. This configuration can allow the cap adhesive 801 to fill the gaps between the filter media 700 and the sidewalls 808, 810, and 812 of the second end cap 710 while allowing the filter media 700 to extend from the first support member sidewall 810 to the second support member sidewall 812 (which can maximize the surface area of ​​the filter media 700). In other words, the filter media thickness 814 of the filter media 700 can generally correspond to the sidewall separation distance 816 extending between the first support member sidewall 810 and the second support member sidewall 812 (e.g., within 1%, 2%, 3%, 4%, or 5% of the sidewall separation distance). The filter media thickness 814 extends from the dirty air side 704 to the clean air side 706 of the filter media 700. The filter media thickness 814 can be, for example, about 10.7 millimeters (mm) (e.g., within 1%, 2%, 3%, 4%, or 5% thereof). The end cap thickness 818 can be, for example, about 15 mm.

[0058] Cap adhesive 801 may be a two-part adhesive, such as an epoxy mixed with a multifunctional hardener to allow time for filter media 700 to be positioned within second end cap 710 before the adhesive cures. When assembling filter 304, filter media 700 may be adhesively coupled to filter support 712, for example, prior to adhesively coupling to first end cap 708 and second end cap 710. If pleated filter media 700 is used, hot melt glue may be applied across the pleats before filter media 700 is coupled to filter support 712, which may increase the stiffness of filter media 700.

[0059] Fig. 9An illustrative example of a filter 900 having a filter medium 902 and an end cap 904 is shown. As shown, a first adhesive 906 extends along a first side wall 908, and a second adhesive 907 extends along a second side wall 909. The first side wall 908 extends along a dirty air side 910 of the filter medium 902, and the second side wall 909 extends along a clean air side 911 of the filter medium 902. Thus, the filter thickness 912 is limited by the first adhesive thickness 914 and / or the second adhesive thickness 915, which can reduce the overall surface area of ​​the filter 900 (when compared to the surface area of ​​the filter 900). Figure 7 For example, filter 304 can have approximately 37.5% more effective filtration area when compared to filter 900 (assuming filters 304 and 900 have substantially the same overall dimensions). Filter thickness 912 can be, for example, 7.5 mm, first adhesive thickness 914 can be approximately 3.5 mm, and second adhesive thickness 915 can be approximately 1.5 mm.

[0060] An example of a vacuum cleaner according to the present disclosure includes: a suction motor; a body, the body defining a filter cavity, the filter cavity being fluidly coupled to the suction motor and being configured to receive a filter; a filter cover, the filter cover being removably coupled to the body, the filter cover extending over at least a portion of the filter cavity; and a release member, the release member being configured to transition between a release position and a retention position to removably couple the filter cover to the body. The release member includes: a body release portion, at least a portion of the body release portion being rotatably coupled to the body; and a cover release portion, at least a portion of the cover release portion being slidably coupled to the filter cover, wherein rotational movement of the body release portion causes corresponding linear movement of the cover release portion to transition the release member between the release position and the retention position.

[0061] In some cases, the cover release portion may include a latch and the filter cover may include a latch cavity, the latch being slidable in the latch cavity. In some cases, the latch may include an actuated portion configured to engage the body release portion and an actuated portion configured to selectively engage with the body, the latch being configured to slide in the latch cavity in response to the body release portion rotating. In some cases, the actuated portion may include a first leg and a second leg, the first leg being spaced apart from the second leg. In some cases, the first tab may extend from the first leg and the second tab may extend from the second leg. In some cases, at least a portion of the first tab and at least a portion of the second tab may be configured to selectively engage the corresponding latch buckle of the body. In some cases, the tab top surface of the second tab may be offset from the leg top surface of the second leg. In some cases, the latch may be biased in a direction that causes the first tab and the second tab to disengage from the corresponding latch buckle.
