Tip resistant wet/dry vacuum
The present invention provides a wet/dry vacuum cleaner, or a kit for modifying an existing wet/dry vacuum, that includes a hose that is connected to a lower portion of the vacuum such that a pulling force applied to the hose will be applied to the lower portion of the vacuum, thereby preventing the vacuum from tipping over as the unit is pulled around an area using the hose.
The present invention relates to a tip resistant wet/dry vacuum, and in particular to a tip-resistant vacuum and a kit for modifying a vacuum to prevent tipping.
BACKGROUND OF THE INVENTIONWet/dry vacuum cleaners typically include an upright cylindrical housing having an upper portion that contains the power head or motor assembly for generating suction, and a lower portion or canister for collecting debris and water. The power head is positioned at the top of the canister to allow a suction force to be create within the canister, while preventing water and/or debris collected in the lower portion of the housing from interfering with and possibly causing damage to the motor assembly. Existing wet/dry vacuum cleaners also include a hose or other device for directing the suctioning force of the motor assembly to collect and deliver debris to the canister. Like the motor assembly, the hose must be connected to the top of the lower portion or to the upper portion of the housing to prevent water and/or debris from interfering with the suctioning force.
Such a configuration can disadvantageously result in tipping of the vacuum for several reasons. Since the power head on the vacuum contains the motor, fan, and other components for creating suction, the typical wet/dry vacuum is extremely top heavy. This top heavy condition may become less sever as debris is collected, however most canisters continue to remain unstable even with the heaviest loads. Most wet/dry vacuums include casters or wheels to facilitate movement of the vacuum cleaner. As a result, most users will pull on the hose, rather than the vacuum cleaner, to move the vacuum around a room. Since the pulling force is being applied at the top of the unit, tipping of the vacuum can easily occur when the canister is empty or when the casters are unable to roll as a result of a blockage, such as cord interference.
Accordingly, there remains a need for an improved wet/dry vacuum that is tip resistant.
SUMMARY OF THE INVENTIONThe present invention generally provides a tip resistant wet/dry vacuum that includes a housing having an upper portion containing a motor assembly for creating a suction force within the housing, and a lower portion having a collection tank adapted to retain fluid and/or debris therein. The lower portion includes a top end, a bottom end, and a sidewall extending therebetween. At least one caster is mated to the lower portion of the housing to allow rolling movement of the housing. The vacuum further includes a hose that is coupled to the sidewall adjacent the bottom end of the lower portion of the housing such that a pulling force applied to the hose will be transferred to the bottom end of the lower portion of the housing to prevent tipping of the housing. The hose further includes an outlet adapted to deposit fluid and/or debris adjacent to the top end of the lower portion of the housing wherein the fluid and/or debris is collected in the collection tank.
In one embodiment, the outlet of the hose can be coupled to a port formed in the sidewall adjacent to the top end of the lower portion of the housing and in communication with the collection tank, and a portion of the hose can be connected to the sidewall adjacent to the bottom end of the lower portion of the housing. The vacuum can also include a mating element for mating a portion of the hose to the sidewall adjacent to the bottom end of the lower portion of the housing. The mating element can optionally be removably matable to the sidewall of the housing. Suitable examples of mating elements for use with the present invention include a clip, a cord, a bracket, a strap, a tab, and a fastener.
In another embodiment, the outlet of the hose can be coupled to a port formed in the sidewall adjacent the bottom end of the lower portion of the housing. An extension hose is preferably disposed within the lower portion of the housing, and it includes a first end coupled to the port and a second end disposed adjacent the top end of the lower portion of the housing for delivering fluid and/or debris to the collection tank. A mating element, such as an L- or U-shaped connector, a clip, a bracket, a cord, a strap, a tab, and a fastener, can be provided for mating a portion of the second end of the extension hose to an internal surface of the sidewall adjacent the top end of the lower portion of the housing.
The present invention also provides a kit for creating a tip-resistant wet/dry vacuum. The kit preferably includes a connector member having a first end adapted to mate to a hose on a wet/dry vacuum, and a second end adapted to mate to an extension hose. The connector member is preferably configured to be disposed within an opening formed in a sidewall of a wet/dry vacuum. The kit also includes an extension hose having a first end adapted to mate to the second end of the connector member, and a second, open end for delivering fluid and/or debris to a collection chamber formed in a wet/dry vacuum. A mating element can be provided for mating a portion of the second end of the extension hose to an inner sidewall of a housing in a wet/dry vacuum to allow fluid and/or debris to be delivered to the collection chamber in the wet/dry vacuum. The mating element can be, for example, an L- or U-shaped connector, a clip, a bracket, a cord, a strap, a tab, and a fastener. In another embodiment, rather than including an extension hose, the kit can include a housing having a lumen extending therethrough, and the mating element can be effective to mate the housing to an inner or outer sidewall of an existing wet/dry vacuum. The kit can also optionally include a sealing member, such as a cap, that is adapted to seal an existing inlet port on a wet/dry vacuum.
BRIEF DESCRIPTION OF THE DRAWINGSThe invention will be more fully understood from the following detailed description taken in conjunction with the accompanying drawings, in which:
The present invention provides a wet/dry vacuum cleaner having, or a kit for modifying an existing wet/dry vacuum to have, a hose that is connected to a sidewall of the vacuum adjacent to a bottom end of the vacuum such that a pulling force applied to the hose will be applied to the bottom portion of the vacuum, thereby preventing the vacuum from tipping over during use as the unit is pulled around an area using the hose. As an initial matter, it is worth noting that although an exemplary embodiment of a vacuum cleaner will be described in some detail, the collection tank, motor assembly, casters, and other components are not essential to the invention and these components are merely described for illustration purposes. Thus, a person skilled in the art will appreciate that the vacuum can have virtually any configuration, shape, and it can include a variety of components and features known in the art.
The motor assembly 14 in the upper portion 10a of the housing can have virtually any configuration, and a variety of motor assemblies 14 are known in the art and can be used with the present invention. A typical motor assembly 14 includes a power head, which contains the motor, fan, an other components for creating a vacuum force within the tank 12. A power cord 15 is connected to the motor assembly 14 for supplying power to the motor assembly 14. The motor assembly 14 also preferably includes an automatic shut-off valve (not shown) that is effective to deactivate the motor when the vacuum 10 tips over. This feature is generally required with wet/dry vacuums to prevent fluid and/or debris from interfering with or causing damage to the motor assembly 14. Moreover, most wet/dry vacuums require a floating ball or other device that is effective to shut off the motor assembly 14 when the collection tank 12 is full. This mechanism will also prevent fluid and/or debris from interfering with the delivery of fluid and/or debris from the hose 16 to the collection tank 12.
The lower portion 10b of the housing can also have a variety of configurations, but in general it includes a top end 12a and a bottom end 12b that extends between a sidewall which forms the collection tank 12 for collecting fluid and/or debris. A hose 16 is coupled to an outlet 20 that is formed in the sidewall of the housing, and it is in communication with the tank 12. The hose 16 can have virtually any configuration, but in general it includes an inlet end 16a for receiving fluid and/or debris, and an outlet end 16b for delivering the fluid and/or debris to the collection tank 12. A person skilled in the art will appreciate that the hose 16 can have any configuration, and it can be formed from one or more lengths of hoses that are connected to one another. Moreover, the term “hose” is also intended to include a variety of detachable and interchangeable nozzles and hoses that can be attached to either the inlet end 16a of the hose 16 or to the outlet 20 formed in the lower portion 10b of the housing. The lower portion 10b of the housing also preferably includes one or more casters or wheels 18 coupled thereto, and preferably mated to the bottom end 12b of the housing, for allowing the vacuum 10 to roll during use.
As is further illustrated in
In order to provide a hose 16 that is coupled near the bottom end 12b of the vacuum 10, the vacuum 10 must be adapted such that the fluid and/or debris is still deposited into the tank 12 adjacent to the top end 12a of the lower portion 10b of the housing. This is necessary in order to prevent the fluid and/or debris from interfering with the suction force created by the motor assembly 14 and applied to the hose 16. Accordingly, the present invention provides several exemplary techniques for depositing fluid and/or debris adjacent to the top end 12a of the lower portion 10b of the housing, while allowing at least a portion of the hose 16 to remain connected to the lower portion 10b of the housing adjacent to the bottom end 12b to prevent tipping of the vacuum 10 during use. While virtually any technique can be used to redirect debris from the bottom end 12b of the lower portion 10b of the housing to the top end 12a of the lower portion 10b of the housing,

A person skilled in the art will appreciate that, while the hose in each of
In another embodiment of the present invention, the extension hose 117, 217, and clip 222, L-shaped bracket 124, or other mating element, can be provided as a kit to allow a person to modify an existing wet/dry vacuum to provide a tip-resistant wet/dry vacuum. In an exemplary embodiment, the kit preferably includes a connector member (not shown), similar to outlets 20, 120, and 220 shown in
A person skilled in the art will appreciate that the kit can include a variety of components not shown or described herein, as long as the components are effective to allow an existing wet/dry vacuum to be modified such that the pulling force applied to the hose will be transferred to the bottom end of the housing. By way of non-limiting example, the kit can include a housing that is adapted to mate to an outer or inner surface of an existing wet/dry vacuum, and that includes a lumen extending therethrough that is effective to direct debris from a hose connected to the bottom end of the housing to the top end of the housing for delivery into the collection tank.
As shown, the vacuum 310 generally includes an upper portion 310a that contains a motor assembly 314, and a lower portion 310b that includes a collection tank 312, and one or more casters or wheels 318 disposed under the lower portion 310b. An outlet port 320 is formed in the lower portion 310b of the housing and it is in communication with the collection tank 312 and with the motor assembly 314 such that the motor assembly 314 is effective to create a suction force within the collection tank 312 and a hose 316 coupled to the outlet port 320. The outlet port 320, rather than being positioned adjacent to the bottom of the lower portion 310b of the unit, is formed at the top end 312a of the lower portion 310b of the housing, as is standard on existing wet/dry vacuums. Unlike prior art vacuums, however, a clip 322, similar to clip 222 shown in
The clip 322 can have virtually any configuration, but like clip 222 shown in
A person skilled in the art will appreciate that a variety of other techniques can be used to provide a wet/dry vacuum wherein the pulling force applied to the hose will be transferred to the base of the unit, rather than to the upper portion of the housing, as is done in existing wet/dry vacuums. By way of non-limiting example, a cord can be provided and attached to a portion of the hose. The opposed end of the cord can then be attached to the base of the unit such that the length of the cord extending between the hose and the vacuum is shorter than the length of the hose extending from the attachment point of the cord to the vacuum. As a result, when a pulling force is applied to the hose, the cord, rather then portion of the hose attached to the vacuum, will receive the pulling force. The force will thus be applied to the base of the unit, thereby preventing the unit from tipping over as the vacuum is pulled around an area using the hose.
One skilled in the art will appreciate further features and advantages of the invention based on the above-described embodiments. Accordingly, the invention is not to be limited by what has been particularly shown and described, except as indicated by the appended claims.
