VACUUM CLEANER WITH HAND NOZZLE

Abstract

A vacuum cleaner includes a floor nozzle, a handle, a hand nozzle that can be stored at least partially in the handle, and a backbone between the floor nozzle and the handle. The vacuum cleaner further includes a motor and dustcup on the backbone. Air flow conduits define a first air flow path between the dustcup and the floor nozzle and a second air flow path between the hand nozzle and the dustcup. A flow valve is operable between an open position and a closed position based on the position of the backbone relative to the floor nozzle. When the valve is in the open position, the first air flow path is open to the floor nozzle; when the valve is in the closed position, the first air flow path is closed to the floor nozzle, focusing suction to the hand nozzle.

Description

TECHNICAL FIELD

The present disclosure relates generally to vacuum cleaners and more particularly to a vacuum cleaner having a floor nozzle and a hand nozzle.

BACKGROUND

Many types of vacuum cleaners exist, the most common types being upright and stick vacuum cleaners. Upright vacuum cleaners typically combine the motor and floor nozzle into a single assembly and have a handle that extends up from the floor nozzle to support a dustcup or bag. Upright vacuum cleaners traditionally have been known for having a large dustcup capacity and superior suction. Stick vacuum cleaners, on the other hand, have a floor nozzle, a handle that includes the dustcup and motor, and a tube between the floor nozzle and dustcup. The stick vacuum cleaner traditionally has been more lightweight and has a slim design for under-furniture reach, although has reduced dustcup capacity and suction.

SUMMARY

The present disclosure relates to a vacuum cleaner with a hand wand that can be deployed for cleaning crevices and above-floor areas. In some embodiments, the hand wand can be stored in the handle of the vacuum cleaner and may be deployed by itself or together with an extension conduit connected to the handle.

In another aspect, the present disclosure relates to a valve for directing air flow to either the floor nozzle or to the hand nozzle based on the position of the vacuum cleaner's backbone relative to the floor nozzle. For example, when the backbone is in an upright position, the valve is closed to the floor nozzle, thereby focusing suction through the hand nozzle.

The features and advantages described herein are not all-inclusive and, in particular, many additional features and advantages will be apparent to one of ordinary skill in the art in view of the drawings, specification, and claims. Moreover, it should be noted that the language used in the specification has been selected principally for readability and instructional purposes and not to limit the scope of the disclosed subject matter.

DETAILED DESCRIPTION

Disclosed is a vacuum cleaner comprising a floor nozzle, a handle, a hand nozzle stored at least partially in the handle, and a backbone between the floor nozzle and the handle. The vacuum cleaner further includes a motor and dustcup on the backbone. Air flow conduits define a first air flow path between the dustcup and the floor nozzle and a second air flow path between the hand nozzle and the dustcup. A flow valve is operable between an open position and a closed position based on the position of the backbone relative to the floor nozzle. For example, when the backbone is oriented in an upright position (e.g., 90°±5°) with respect to the floor nozzle, the flow valve is closed. In other positions (e.g., 100° to 180°) the flow valve is open. When the valve is in the open position the first air flow path is open to the floor nozzle and when the valve is in the closed position the first air flow path is substantially closed to the floor nozzle, thereby focusing suction to the hand nozzle. Storing the hand nozzle in the handle closes the second air flow path by the hand nozzle substantially forming a seal with the handle.

In some embodiments, the hand nozzle fluidly communicates with a rigid extension conduit connected to the handle when the hand nozzle is in the stored position. The extension conduit structurally connects the handle to the backbone so that the user can maneuver the vacuum cleaner when using the floor nozzle. On one hand, the user can use the hand nozzle by removing it from the stored position in the handle. Alternately, the user can remove the extension conduit from a receptacle in the top of the backbone and can use the handle to aim the extension conduit to its desired location. Storing the hand nozzle in the handle fluidly connects the hand nozzle to the extension conduit. When the extension conduit is stored in the receptacle on the dustcup, the extension conduit substantially forms a seal with the conduit, preventing air flow through the second air flow path via the hand nozzle.

Overview

One challenge associated with existing stick vacuum cleaners is not having an ability to perform above-floor cleaning. For example, stick vacuum cleaners may be made with a motor and dustcup located at or closely adjacent the handle. By doing so, the vacuum cleaner may omit a hand nozzle due to the position and weight of the motor and dustcup. Another deficiency of existing vacuum cleaners equipped with a hand nozzle is that the suction through the hand nozzle is split between the hand nozzle and the floor nozzle, resulting in insufficient suction. Additionally, the flexible tube for existing hand nozzles is part of the primary air path into the dustcup from the floor nozzle, resulting in power losses. As a result, the tube must be sized larger to accommodate larger debris picked up by the floor nozzle, which increases the overall weight of the vacuum cleaner.

It would be desirable for a compact vacuum cleaner to include a hand nozzle. It would also be desirable for all or a vast majority of suction to pass through the hand nozzle when the hand nozzle is in use and for air flow to not pass through the flexible tube when the hand nozzle is not being used. The present disclosure addresses these needs and others by providing a stick-type vacuum cleaner with a hand nozzle. In one embodiment, the vacuum cleaner includes a valve that closes air flow to the floor nozzle when the backbone is in the upright condition. In such case, suction is directed to the hand nozzle and closed to the floor nozzle. After stowing the hand nozzle, the user may tilt the backbone to its in-use position, opening the valve to the floor nozzle.

Numerous variations and embodiments will be apparent in light of the present disclosure.

Example Embodiments

FIG. 1 illustrates a side view of a vacuum cleaner 100 with a floor nozzle 120, backbone 140 with battery packs 160 and dustcup 180, and handle 200 with hand nozzle 220, in accordance with an embodiment of the present disclosure. In this example, the floor nozzle 120 is on a horizontal surface or floor 10 and the backbone 140 is in an upright position. In the upright position, the backbone 140 is substantially oriented at 90° (e.g., ±5°) to the floor 10. The hand nozzle 220 is shown in a stored condition with part of the hand nozzle 220 received in the handle 200.

The vacuum cleaner 100 includes a plurality of conduits 102a, 102b, 102c (collectively or generally, conduits 102) that define a first air flow path between the floor nozzle 120 and the dustcup 180, and a second air flow path between the hand nozzle 220 and the dustcup 180. In this example, a first flexible conduit 102a extends from the floor nozzle 120, through a pivot joint, and towards a base 140a of the backbone 140. The flexibility of the first flexible conduit 102a accommodates various positions of the backbone 140 with respect to the floor nozzle 120, including the upright position (e.g., as shown) and other positions in which the backbone 140 defines an angle from 85° to 180° with the floor 10 (and floor nozzle 120), for example. The backbone 140 can define or include a conduit between the first flexible conduit 102a and the dustcup 180. A second flexible conduit 102b extends between the backbone 140 and the hand nozzle 220. The handle 200 includes or is connected to a rigid conduit 102c that extends between the backbone 140 and the handle 200. A distal end of the rigid conduit 102c is received in a receptacle 142 at the top of the backbone 140. The receptacle 142 can be a dead end such that when the hand nozzle 220 is in the stowed position and the rigid conduit 102c is received in the receptacle 142, the second air flow path is closed at one end. For example, the rigid conduit 102c forms a seal with the receptacle 142 (a dead end) and the hand nozzle 220 forms a seal with the handle 200.

In some embodiments, the air flow through the first and/or second air flow paths is determined, at least in part, by the orientation of the backbone 140 with respect to the floor nozzle 120. For example, the first flexible conduit 102a between the floor nozzle 120 and the base 140a of the backbone 140 includes a valve 144 (not visible), such as a pinch valve, that is closed when the backbone is in the upright position. In some embodiments, the valve 144 is closed or substantially closed (e.g., at least 90% flow restriction) when the backbone 140 is substantially upright (e.g., 90°±5°). Thus, when the user removes the hand nozzle 220 from the handle 200 or the rigid conduit 102c from the receptacle 142, air flow to the dustcup 180 takes the path of least resistance and flow is concentrated through the hand nozzle 220.

In some embodiments, the air flow through the first and/or second air flow paths can be determined, at least in part, by a position of the handle 200 with respect to the backbone 140. For example, the handle 200 can telescope between a retracted or compact position and a deployed or extended position, where moving the handle 200 to the retracted position closes the first air flow path to the floor nozzle 120 and opens the second air flow path to the hand nozzle 220, and where moving the handle 200 to the deployed position (e.g., as shown in FIG. 1) closes the second air flow path to the hand nozzle 220 and opens the first air flow path to the floor nozzle 120.

FIGS. 2 and 3 illustrate side views of the vacuum cleaner 100 of FIG. 1 with the backbone 140 in the upright position and the hand nozzle 220 in a deployed position, in accordance with an embodiment of the present disclosure. In these examples the hand nozzle 220 includes a first rigid section 224 and a second rigid section 226 oriented transversely to the first rigid section 224 to define angle β from 60° to 100°, such as about 75° when in the stowed position (e.g., as shown in FIG. 2). When stowed in the handle 200 (e.g., shown in FIG. 1), the first rigid section 224 abuts and is partly received in a half channel defined by a vertical portion 200a of the handle 200 where it can function as part of the handle 200 for lifting or moving the vacuum cleaner 100. The second rigid section 226 is received in a hollow horizontal or generally horizontal portion 200b and forms a seal with the handle 200, which fluidly communicates with the rigid conduit 102c. Here, the hand nozzle 220 includes a pivot joint 222 between the first and second rigid sections 224, 226, enabling the user to pivot the second rigid section 226 as desired for a particular cleaning task.

FIGS. 4 and 5 illustrate side views of a vacuum cleaner 100 with the backbone 140 in an upright position and the hand nozzle 220 in a deployed position together with the handle 200 and rigid conduit 102c, in accordance with an embodiment of the present disclosure. The rigid conduit 102c has been removed from the receptacle 142 at the top of the backbone 140, such as by pressing a release button or catch 143 and pulling upward on the handle 200. The rigid conduit 102c fluidly connects to the handle and provides an extension of the hand nozzle 220. In use, the pivot joint 222 enables the user to use the previously horizontal portion 200b of the handle 200 as a grip to direct the rigid conduit 102c to the desired location.

FIG. 6 illustrates a top and rear perspective view of a hand nozzle 220, in accordance with an embodiment of the present disclosure. The hand nozzle 220 includes first rigid section 224 and second rigid section 226 joined at a pivot joint 222 that includes part of the air flow path. In one embodiment, the first rigid section 224 has a cylindrical geometry and the second rigid section 226 a flattened cylinder shape, such as an elliptical or rectangular cross-sectional shape.

FIG. 7 illustrates a side view and FIG. 8 illustrates a rear cross-sectional view of a hand nozzle 220, in accordance with another embodiment of the present disclosure. Air flow is shown using broken lines. The hand nozzle 220 includes first rigid section 224 and second rigid section 226 joined at a pivot joint 222 that includes part of the air flow path, similar to embodiments discussed above. In one embodiment, the first rigid section 224 has a cylindrical geometry and the second rigid section 226 a flattened cylinder shape, such as an elliptical or rectangular cross-sectional shape. As can be seen in FIG. 8, part of the air flow passes laterally through the pivot joint 222 between the first and second rigid sections 224, 226.

FIGS. 9 and 10 show a side and front perspective views, respectively, of a valve 144 configured as a pinch valve, in accordance with an embodiment of the present disclosure. In FIG. 9 the backbone 140 is in an upright position with respect to the floor nozzle 120. The valve 144 is shown in the closed position in FIG. 9 and is shown in an open position in FIG. 10. A length of flexible conduit 102d is between the floor nozzle 120 and a conduit 102e extending through or connecting to the backbone 140. In one example, the flexible conduit 102d is housed within a lower portion of the backbone 140, such as being positioned above the hinge 126 and below the dustcup 180 (shown in FIG. 1). The flexible conduit 102d is shown as connecting to the first flexible conduit 102a, but it can continue to the floor nozzle 120 in place of the first flexible conduit 102a in some embodiments. In this example, the valve 144 is configured as a pinch valve that includes a pinch bar 146 configured to pivot against the flexible conduit 102d, closing the air flow pathway through it. In this example, the pinch bar 146 is attached at its ends to a yoke 148 that is pivotably connected to the hinge 126 or pivot point between the floor nozzle 120 and backbone 140. As the backbone 140 moves towards the upright position, the yoke 148 contacts stops 128 that prevent further pivot of the yoke 148 as the backbone 140 proceeds to the upright position, causing the pinch bar 146 to collapse the flexible conduit 102d. To ensure the flexible conduit 102d returns to the open position when moving the backbone 140 to the in-use position, the flexible conduit 102d optionally includes a loop 145 around the pinch bar 146.

Referring now to FIGS. 11-15, a valve 144 configured as a scissor-type pinch valve is shown in various views, in accordance with an embodiment of the present disclosure. FIG. 11 is a top, rear, and side view showing the valve 144 in an open position; FIG. 12 is a top, front, and side view showing the valve 144 in an open position; FIG. 13 is a side and front perspective view showing the valve 144 in a closed position where the flexible conduit 102d is omitted to more clearly show other components of the valve 144; FIGS. 14 and 15 are side views showing the valve 144 in open and closed positions, respectively. Note that in FIG. 15 the flexible conduit 102d is illustrated in an uncompressed or open state rather than being pinched closed between the valve 144 as it would be during operation of the valve 144. The closed position of the flexible conduit 102d is illustrated in broken lines. FIGS. 11-15 will be discussed concurrently below.

As noted above, the valve 144 is configured as a scissor-type pinch valve and includes a first pinch bar 146a on a first yoke 148a and a second pinch bar 146b on a second yoke 148b, where each pinch bar 146 extends laterally between arms of the respective yoke 148. Each pinch bar 146 can be a roller in some embodiments. A length of flexible conduit 102d is between the first and second pinch bars 146a, 146b. In this example, the flexible conduit 102d connects to another flexible conduit 102a, which extends at least partially through the first and second frame portions 130, 132 between the floor nozzle 120 and the backbone 140 (shown, e.g., in FIGS. 1 and 10).

The first frame portion 130 is pivotably connected to a second frame portion 132 at a pivot point or hinge 126. The first and second frame portions 130, 132 can be made of rigid materials such as metal or plastic. The first frame portion 130 is generally oriented in a horizontal position and connects to the floor nozzle 120. The second frame portion 132 extends from the first frame portion 130 to define an angle α from 0° to about 100°. As shown in FIGS. 11-15, the first frame portion 130 is oriented at an angle α from about 80° to about 100°. It will be appreciated that the second frame portion 132 can pivot downward so that the angle α between these components is larger, such as an angle α of 120°, 135°, or even 180°. The second frame portion 132 can be part of the backbone 140 or can connect to the backbone 140. In some embodiments, the flexible conduit 102d fluidly connects to the backbone 140 using a connector 150, such as a tubing connector having a slip fit, compression fitting, weld, adhesive, clamp, or other suitable connection.

In this example, the connector 150 connects to the flexible conduit 102d using a hose clamp 152 and has a tapered section 154 that can be received in the conduit of the backbone 140. An upper end portion of the second frame portion 132 is secured to a body 151 of the connector 150, such as by fasteners. As a result, the second frame portion 132 pivots together with the backbone 140 during use of the vacuum cleaner 100. The flexible conduit 102d is also secured to the flexible conduit 102a using a hose clamp 152.

The first yoke 148a of the first pinch bar 146a is attached to the first frame portion 130 at the pivot or hinge 126, such as a fastener, bushing, or other connection. The second yoke 148b of the second pinch bar 146b is attached to the second frame portion 132 by a fastener 149. The first yoke 148a crosses the second yoke 148b. In some embodiments, one or both yokes 148 are pivotably connected to the respective frame portion. In other embodiments, yokes 148a, 148b are fixedly attached to the respective frame portion 130, 132. As the second frame portion 132 is moved to an upright position, such as an angle α from ˜85°-95° with the first frame portion 132, the second yoke 148b contacts the pivot fastener 127 and the first yoke 148a contacts stops 128 on the first frame portion 130 to cause the pinch bars 146 to move towards one another (e.g., as shown in FIG. 13) and squeeze closed the flexible conduit 102d.

FIGS. 14 and 15 illustrate the valve 144 in an open position and a closed position, respectively. In FIG. 14, the second frame portion forms an angle α of about 95° with the first frame portion 130. As a result, the first yoke 148a and second yoke 148b remain in an open position, thereby permitting the flexible conduit 102d to be open for air flow therethrough. In FIG. 15, the second frame portion 132 has moved to the upright position and slightly beyond, where the angle α between the first frame portion 130 and second frame portion 132 is about 85°. In this position, the first and second yokes 148a, 148b have pivoted towards one another, closing the first and second pinch bars 146a, 146b on the flexible conduit 102d, closing it (as shown in broken lines). In moving to the position shown in FIG. 15, first yoke 148a rotates until making contact with the first frame portion 130, such as at stops 128 (shown in FIG. 13). As the second frame portion 132 rotates about pivot 126, a base 155a of the first yoke 148a contacts the base 155b of the second yoke 148b and functions as a cam to pivot the second yoke 148b at a greater rotational rate. As a result, the first and second pinch bars 146a, 146b move towards one another to close the flexible conduit 102d. Other mechanisms can be used to close the pinch bar(s) 146. Loop 145 discussed above can be similarly employed in the embodiment shown in FIGS. 11-15.
