LID FOR WET/DRY VACUUM CLEANER WITH INTEGRATED HOSE RETAINER
A vacuum cleaner includes a canister, a vacuum hose, a motor, an impeller, and a one piece lid. The canister defines a debris chamber and has a top. The impeller is connected to the motor and is operable to generate air flow upon operation of the motor. The one piece lid includes a hose retainer and is mounted to the top of the canister. The hose retainer includes at least two retaining tabs spaced from a central portion of the lid to define an insertion opening. The retaining tabs deflect away from a retention position in a first direction to an open position when the vacuum hose is inserted through the insertion opening. The retaining tabs are biased in a second direction towards the retention position such that the retaining tabs exert a positive retention force on the vacuum hose when positioned within the hose retainer.
The field of the disclosure relates generally to vacuum cleaners and, more particularly, to vacuum cleaner lids including an integrated hose retainer.
BACKGROUNDSome vacuum appliances, in particular vacuum cleaners, include lid-mounted motors that facilitate the movement of air using a motor and an impeller connected to the motor. Some vacuum cleaners also include hoses to facilitate collection of debris or liquids and hose storage systems to facilitate storage of the hose. Typical hose storage systems include a retention device configured to retain the hose within the hose storage system. However, at least some known retention devices loosely retain the hose within the hose storage system because the retention device does not exert a positive retention force on the hose.
Additionally, some hose storage systems require assembly by the manufacturer or the customer. Typically, the manufacturer or the customer assembles the hose storage system by fastening the retention device to a portion of the vacuum. However, the fit of the hose within the retention device and/or the hose storage system can vary based on manufacturing tolerances of the components and in the assembly process. Also, some customer assembled hose storage systems require the customer to install the retention device with screws that fasten the retention device to the vacuum cleaner. If the customer installs incorrectly, the screws might puncture the vacuum cleaner. A more reliable and more cost effective hose storage system is needed.

DETAILED DESCRIPTIONIn the illustrated embodiment, the power head 114 is detachable from the lid 110 and the vacuum cleaner 100 to facilitate use of the power head 114 apart from the vacuum cleaner 100. For example, the power head 114 may be detached from the vacuum cleaner 100 and used as a blower or other suction unit. In alternative embodiments, the power head 114 may not be detachable from the lid 110 or the vacuum cleaner 100. Rather, the power head 114 may be integrally formed with the lid 110 and/or the vacuum cleaner 100.
Although the vacuum cleaner 100 is shown and described with reference to a wet/dry vacuum cleaner, the vacuum cleaner 100 and features thereof may be embodied in vacuum cleaners other than wet/dry vacuum cleaners including, for example and without limitation, canister vacuum cleaners, backpack vacuum cleaners, and upright vacuum cleaners.
The vacuum cleaner 100 includes a vacuum cleaner hose 122 and a plurality of vacuum cleaner accessories 124. As used herein, the term “vacuum cleaner hose” or “hose” refers to a component of a vacuum cleaner that is connected, directly or indirectly, to a vacuum cleaner inlet port or outlet port to direct airflow or suction generated by the vacuum cleaner. Examples of vacuum cleaner hoses and accessories may include, for example and without limitation, vacuum hoses, vacuum conduits, vacuum wands or tubes, and surface cleaning tools. In the illustrated embodiment, a proximal end 126 of the vacuum cleaner hose 122 is extends from the inlet 104 and permits fluid communication between a surface to be cleaned and the vacuum cleaner 100. Additionally, one or more vacuum cleaner accessories 124 may extend from a distal end 128 of the vacuum cleaner hose 122 and permit fluid communication between the surface to be cleaned and the vacuum cleaner hose 122 and/or the vacuum cleaner 100. The vacuum cleaner hose 122 includes a hose diameter 130. In the illustrated embodiment, the hose diameter 130 is about 2.392 inches to about 2.408 inches. In alternative embodiments, the hose diameter 130 may be any length that enables the vacuum cleaner 100 to operate as described herein.
As shown in
The power head retention device 138 and the power head pin retainer 140 extend from the power head platform 146 and are positioned on opposite sides of the power head platform 146. In the illustrated embodiment, the power head retention device 138 includes a latch. In alternative embodiments, the power head retention device 138 includes any device that facilitates retaining the power head 114 on the lid 110. The power head pin retainer 140 includes two pin receiving holes 150 configured to receive and retain a plurality of pins (not shown) on the power head 114. The power head 114 includes a latching pin (not shown) with a shape complementary to the power head retention device 138. In order to insert the power head 114 onto the lid 110, the pins on the power head 114 are inserted into the pin receiving holes 150 and the power head 114 is rotated such that the latching pin on the power head 114 is inserted into the power head pin retainer 140. The power head pin retainer 140 is then latched onto the latching pin on the power head 114, securing the power head 114 to the lid 110.
An integrally formed lid disc 152 extends from the power head platform 146. The lid disc 152 includes an inner diameter 154 coupled to the power head platform 146 and an outer diameter 156. The hinge mechanisms or latches 118a and 118b and the hose retainer 132 are coupled to the outer diameter 156 and positioned around the outer diameter 156. A hose retention track 158 is a generally circular track circumscribing the power head platform 146 and configured to retain and store the vacuum cleaner hose 122. The hose retention track 158 includes an inner track diameter 160 and an outer track diameter 162. The inner track diameter 160 is defined by the power head platform 146, the power head retention device 138, and the power head pin retainer 140. The outer track diameter 162 is defined by the hinge mechanisms or latches 118a and 118b, the hose retainer 132, and the outer diameter 156 of the lid disc 152. The lid disc 152 supports the vacuum cleaner hose 122 when it is stored in the hose retention track 158. As such, the hose storage system 131 includes the hose retainer 132, the power head pin retainer 140, the power head platform 146, the hinge mechanisms or latches 118a and 118b, and lid disc 152, all of which facilitate storage and retention of the vacuum cleaner hose 122 when it is stored in the hose storage system 131.
The retaining tabs 168 and the retain tab support prongs 166 are configured to exert a positive retention force on the vacuum cleaner hose 122 when it positioned within the hose retainer 132. Specifically, the retaining tabs 168 are configured to deflect away from a retention position to an open position upon insertion of the vacuum cleaner hose 122 through the insertion opening 169. The retention position is the configuration shown in
In the illustrated embodiment, the retaining tab support prongs 166 extend from the lid disc 152 and the retaining tabs 168 extend from the retaining tab support prongs 166. The retaining tab support prongs 166 are spaced apart from each other and define two prong holes 170 therebetween. The prong holes 170 enable the retaining tabs 168 to be molded and integrally formed with the lid 110 during the manufacturing process. Specifically, the prong holes 170 are positioned relative to the retaining tabs 168 and the retaining tab support prongs 166 such that the retaining tabs 168 may be manufactured in an injection mold with a single direction of motion. In the illustrated embodiment, the retaining tab support prongs 166 and the retaining tabs 168 have an arcuate or curved shape commentary to a cylindrical shape of the vacuum cleaner hose 122 such that an overall shape of the hose retainer 132 is complementary to the cylindrical shape of the vacuum cleaner hose 122.
In the illustrated embodiment, the retaining tab support prongs 166 extend from the lid disc 152 in a direction 174 substantially parallel to a plane of the lid disc 152. The retaining tabs 168 extend from the retaining tab support prongs 166 in a direction 176 substantially perpendicular the plane of the lid disc 152. The retaining tabs 168 include a vertical portion 178 and a curved portion 180. The vertical portion 178 extends from the retaining tab support prongs 166 and the curved portion 180 extends from the vertical portion 178.
During operations, vacuum cleaner hose 122 is inserted into the hose retention area 164 for storage. The insertion angle 188 allows the retaining tabs 168 to flex outwards or in a direction 200 away from the retention position to the open position during the insertion process. The retaining tabs 168 are biased to the retention position and return to the retention position after the vacuum cleaner hose 122 is inserted into the hose retention area 164. In the illustrated embodiment, the insertion angle 188 is about 185 degrees to about 195 degrees. More particularly, the insertion angle 188 is about 190 degrees. If the insertion angle 188 is greater than 195 degrees or less than 185 degrees, the retaining tabs 168 may collapse inwards during the insertion process.
In the illustrated embodiment, the insertion width 196 is about 78% to about 82% of the hose diameter 130. The insertion width 196 dictates how far the retaining tabs 168 will flex in the direction 200 during the insertion process. If the insertion width 196 is less than about 78% of the hose diameter 130, the retaining tabs 168 will be subjected to high stress that can cause the retaining tabs 168 to deform or break during the insertion process. If the insertion width 196 is greater than about 82% of the hose diameter 130, the retaining tabs 168 may not adequately retain the vacuum cleaner hose 122 within the hose retention area 164.
During operations, vacuum cleaner hose 122 is removed from the hose retention area 164 for insertion into the inlet 104 and use to clean a surface to be cleaned. The retaining angle 190 dictates the extraction force required to remove the vacuum cleaner hose 122 from the hose retention area 164. In the illustrated embodiment, the retaining angle 190 is about 50 degrees to about 60 degrees. More particularly, the retaining angle 190 is about 55 degrees. If the retaining angle 190 is less than about 50 degrees, the retaining tabs 168 may not adequately retain the vacuum cleaner hose 122 within the hose retention area 164. If the retaining angle 190 is greater than about 60 degrees, the force necessary to extract the vacuum cleaner hose 122 from the hose retention area 164 may be too high such that the vacuum cleaner 100 would need to be held in place during the extraction process.
The curved portion radius 186 of this embodiment is a radius between about 90% to about 95% of a radius of the vacuum cleaner hose 122 (half of the hose diameter 130). The retaining tabs 168 exert a constant compression force on the vacuum cleaner hose 122 when the vacuum cleaner hose 122 is stored in the hose retention area 164 because the curved portion radius 186 is smaller than the radius of the vacuum cleaner hose 122. Accordingly, the constant compression force enhances the retention capability of the hose retainer 132.
The hose retainers 132 described herein create a positive retention force on the vacuum cleaner hose 122. Specifically, the retaining angle 190 causes the retaining tabs 168 to extend over the hose retention area 164 creating a positive retention of the vacuum cleaner hose 122. Additionally, the curved portion radius 186 is smaller than the radius of the vacuum cleaner hose 122 exerting a constant compression force on the vacuum cleaner hose 122 when the vacuum cleaner hose 122 is stored in the hose retention area 164. As such, the vacuum cleaner hose 122 is retained in the hose retention area 164 by a combination of the constant compression force and the positive retention force on the vacuum cleaner hose 122. Additionally, the insertion angle 188 and the insertion width 196 are configured to allow the vacuum cleaner hose 122 to be inserted into the hose retention area 164 without excessive stress and strain to the retaining tabs 168. The ribs 204 provide structural support to the retaining tab 168 and increases the retention force applied to the vacuum cleaner hose 122.
Example embodiments of vacuum cleaning systems are described above in detail. The vacuum cleaning systems are not limited to the specific embodiments described herein, but rather, components of the vacuum cleaning systems may be used independently and separately from other components described herein. For example, the hose retainer described herein may be used with a variety of vacuum cleaning systems, including and without limitation, vehicular vacuum cleaning systems, wet/dry vacuum cleaners, canister vacuum cleaners, upright vacuum cleaners, and backpack vacuum cleaners.
Embodiments disclosed enable enhanced vacuum cleaner performance without requiring significant or expensive modifications to other components of a vacuum cleaner. Thus, the disclosed hose retainer may be readily incorporated into existing vacuum cleaner designs. The hose retainers described herein create a positive retention force on the vacuum cleaner hose. Specifically, a retaining angle causes retaining tabs of the hose retainer to extend over a hose retention area creating a positive retention force on the vacuum cleaner hose. Additionally, a curved portion radius of a curved portion of the retaining tabs is smaller than a radius of the vacuum cleaner hose, exerting a constant compression force on the vacuum cleaner hose when the vacuum cleaner hose is stored in the hose retention area. As such, the vacuum cleaner hose is retained in the hose retention area by a combination of the constant compression force and the positive retention force on the vacuum cleaner hose. Additionally, an insertion angle and an insertion width are configured to allow the vacuum cleaner hose to be inserted into the hose retention area without excessive stress and strain to the retaining tabs. The ribs formed within the retaining tabs provide structural support and increase the retention force applied to the vacuum cleaner hose.
