Abstract
Description
- This invention relates generally to vacuum cleaners, and more particularly to devices that allow large debris to enter a vacuum cleaner.
- Vacuum cleaners generally include a motor assembly, a tank or other receptacle, a hose inlet on the receptacle, and a hose that attaches to the hose inlet at one end and has a nozzle at the other end. The motor of the motor assembly drives an impeller that creates a low pressure area inside the receptacle. The pressure difference between the inside and the outside of the receptacle creates a suction effect at the hose inlet, which causes dust, debris, and liquids to enter the receptacle through the hose.
- The capability of vacuum cleaners to pick up large debris has been limited to debris that is smaller than the diameter of the hose. Further, even debris that is smaller than the hose diameter may clog the hose when passing through a bend in the hose. A large diameter hose for accepting large debris may not be acceptable because it will reduce the air velocity in the hose inlet, thus reducing the efficiency of the vacuum cleaner. Hoses are often used with nozzles which may have an even smaller cross section, and further increase the likelihood of clogging. Additionally, a hose with limited bending capability to allow passage of large debris reduces the versatility of the vacuum cleaner by making it ineffective for accessing hard to reach areas. Therefore, in most instances, a vacuum cleaner operator must manually pick up large debris and dispose of it by other means.
- The debris access door eliminates the drawbacks noted above in a simple and effective manner.
- Particularly, in accordance with one aspect of the present invention, a vacuum cleaner may include a receptacle and a debris opening in air communication with the receptacle. The vacuum cleaner further includes a lid that is removably attached to the receptacle. Additionally, the vacuum cleaner includes a motor assembly in air communication with the receptacle, a door opening and closing the debris opening, and a hose inlet on the receptacle.
- In accordance with another aspect of the present invention, the debris opening may be on the receptacle.
- In accordance with another aspect the present invention, the debris opening may be in the lid.
- In accordance with another aspect of the present invention, the vacuum cleaner may include an adaptor that is removably connected to the hose inlet at one end and attached to the hose at the other end, where the debris opening is on the adaptor.
- In accordance with another aspect of the present invention, the vacuum cleaner may include an adaptor that is removably connected to the hose inlet at one end and removably connected to the hose at the other end, where the debris opening is on the adaptor.

- Referring initially to FIGS.1-4, a
vacuum cleaner 20 includes areceptacle 22, alid 24, amotor assembly 26, ahose inlet 28, adebris opening 30, and adoor 32 opening and closing the debris opening. Thelid 24 has arim 34 which is designed to fit over the edge of thereceptacle 22 for thevacuum cleaner 20. Around the periphery of thelid 24 are several latch ports 36 (shown in FIGS. 1 and 3) which cooperate with latches 38 (shown in FIGS. 1 and 3) on thereceptacle 22 in order to hold thelid 24 on the receptacle. Thelid 24 houses amotor assembly 26 that is in air flow communication with thereceptacle 22 through a filter 27 (shown in FIGS. 2 and 4). Generally, themotor assembly 26 includes an electric motor, a power cord 29 (shown in FIGS. 2 and 4) for use with an electrical outlet, an air impeller, and other associated equipment (not depicted) that create a low pressure area inside thereceptacle 22. Ahose 39 removably connects at afirst end 40 to ahose inlet 28 on thereceptacle 22. A nozzle 42 (shown in FIGS. 2 and 4) is attached at a second end 44 (shown in FIGS. 2 and 4) of thehose 39 for collecting debris. Thevacuum cleaner 20 can be lifted and moved with ahandle 45 that is placed on thevacuum cleaner 20. Additionally, thevacuum cleaner 20 can be moved with casters 46 (shown in FIGS. 2 and 4). - When the
vacuum cleaner 20 is in operation, the low pressure created in thereceptacle 22 by themotor assembly 26 creates a pressure difference between thereceptacle 22 and thenozzle 42 to cause a suction effect at thenozzle 42. Small debris enters thenozzle 42, travels through thehose 39, and is deposited into thereceptacle 22. The debris opening 30 accommodates large debris that cannot enter or that may become trapped inside of thehose 39. Thedoor 32, having atab 52, rotates about ahinge 54 to open and close the debris opening 30. As seen in FIGS. 2 and 4, the debris opening 30 has afirst end 47 of apipe section 48 with asecond end 50 opening into thereceptacle 22. A vacuum cleaner operator manually picks up large debris, opens thedoor 32, drops the debris in thereceptacle 22 through the debris opening 30, and closes thedoor 32. Although a door set on a rotating hinge is preferred, numerous other types of doors, including removable doors with various closures, and doors with other types of hinges can be used to open and close the debris opening 30. The door may also be spring loaded so that in order to open the door, the force of the spring must be overcome, for instance, by pushing or pulling the door to provide access for the debris. - Described below are other embodiments of the present invention in which certain elements in those other embodiments are identical to elements in the first embodiment. Where elements are identical, they have been given the same numbers throughout the embodiments.
- In a second embodiment of the present invention, as illustrated in FIGS.5-8, the debris opening 30 is in the
lid 24 instead of in the receptable 22 as shown in FIGS. 1-4. Thedebris opening 30 has a first end 47 (shown in FIGS. 6 and 8) of a pipe section 48 (shown in FIGS. 6 and 8) with a second end 50 (shown in FIGS. 6 and 8) having air flow communication within theinside receptacle 22. Thedoor 32 rotates about thehinge 54 to open and close the debris opening 30. A vacuum cleaner operator can manually pick up large debris, open thedoor 32, drop the debris inside thereceptacle 22 through the debris opening 30, and close thedoor 32. - In a third embodiment of the present invention, as illustrated in FIGS.9-12, an
adaptor 60 is removably connected to thehose inlet 28 at a first end 62 (shown in FIGS. 10 and 12) of theadaptor 60 and attached to thehose 39 at a second end 64 (shown in FIGS. 10 and 12) of theadaptor 60. Since theadaptor 60 is attached to thehose 39, it can be considered a part of thehose 39, where the first part of the hose is rigid and the second part of the hose is flexible. Theadaptor 60 comprises a primary pipe 66 (shown in FIGS. 10 and 12) and a secondary pipe 68 (shown in FIGS. 10 and 12). Thesecondary pipe 68 is attached at a first end 70 (shown in FIGS. 10 and 12) to theprimary pipe 66 and is in air flow communication with theprimary pipe 66. A second end 72 (shown in FIGS. 10 and 12) of thesecondary pipe 68 is thedebris opening 30. Thedoor 32 rotates about thehinge 54 to open and close thedebris opening 30. Thefirst end 62 of theadaptor 60 mates with thehose inlet 28 to form a friction fit, similar to the fit that a hose and hose inlet usually have on a vacuum cleaner. Theadaptor 60 can be removed from thevacuum cleaner 20 by pulling thefirst end 62 of theadaptor 60 out of thehose inlet 28. In use, a vacuum cleaner operator can manually pick up large debris, open thedoor 32, drop the debris insidedebris opening 30, and close thedoor 32. The debris will be pulled into therecepticle 22 by the suction created by the vacuum cleaner. In order to minimize clogging of thehose 39, it is advantageous to have thedebris opening 32 located adjacent thehose inlet 28. - In a fourth embodiment of the present invention, as illustrated in FIGS.13-16, an
adaptor 80 is removably connected to thehose inlet 28 at the first end 82 (shown in FIGS. 14 and 16) of theadaptor 80 and removably connected to thehose 39 at the second end 84 (shown in FIGS. 14 and 16) of the adaptor. Theadaptor 80 comprises a primary pipe 86 (shown in FIGS. 14 and 16) and a secondary pipe 88 (shown in FIGS. 14 and 16). Thesecondary pipe 88 is attached at a first end 90 (shown in FIGS. 14 and 16) to theprimary pipe 86 and is in air flow communication with theprimary pipe 86. A second end 92 (shown in FIGS. 14 and 16) of thesecondary pipe 88 is thedebris opening 30. Thedoor 32 having atab 52 rotates about thehinge 54 to open and close thedebris opening 30. Thefirst end 82 of theadaptor 80 mates with thehose inlet 28 to form a friction fit. Thefirst end 40 of thehose 39 mates with thesecond end 84 of the adaptor to form a friction fit. The friction fit at the two ends of theadaptor 80 is similar to the fit that a hose and hose inlet usually have on a vacuum cleaner. Theadaptor 80 can be removed from thevacuum cleaner 20 by pulling thefirst end 82 of theadaptor 80 out of thehose inlet 28. Theadaptor 80 can be removed from thehose 39 by pulling thehose 39 out of thesecond end 84 of theadaptor 80. As with other embodiments, a vacuum cleaner operator can manually pick up large debris, open thedoor 32, drop the debris into thedebris opening 30, and close thedoor 32. - The
adaptor 80 of FIGS. 13-16 can be sold with a vacuum cleaner or can be sold separately for use with existing vacuum cleaners. If sold separately, the ends of theadaptor 80 should be designed to mate with the hose and hose inlet of existing vacuum cleaners. - Although a tank-type vacuum cleaner has been shown in FIGS.1- 16, other types of vacuum cleaners, such as upright vacuum cleaners, back pack vacuum cleaners, etc., may be used in connection with the present invention. In such a situation, the debris opening of the present invention would be placed on such a vacuum cleaner or an adaptor, so that large debris can be placed in the receptacle of the vacuum cleaner, either directly or indirectly.
- The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, as modifications would be obvious to those skilled in the art.
