Abstract
Description
- 1. Field of the Invention
- This invention relates generally to central vacuum cleaners and, more particularly, to a central vacuum cleaner with a nested packaging configuration.
- 2. Description of Related Art
- Central vacuum cleaner systems are well known and in wide use. A conventional system typically includes a power unit (including the vacuum motor and dust receptacle), tubes or pipes plumbed throughout the house (typically inside the house walls), outlets at various locations throughout the house, and a vacuum tool(s) that connects to the outlet, typically via a long, flexible hose. The vacuum tool may be, for example, a powered carpet brush with a beater bar and lamp, an extension wand, a crevice tool, an upholstery tool, and so on.
- In use, one end of the hose is connected to a wall outlet and the other end is connected to a tool. The power unit is then activated and the area within reach of the flexible hose and tool may be cleaned. Dirt, dust and debris is sucked through the hose, through the tubes or pipes and to the power unit where it is filtered and collected.
- In order to provide sufficient vacuum power, filtering capability, dirt and debris collection volume, and to minimize leakage, the central vacuum power unit tends to be quite large. Conventional power units are built and shipped as a single unitary piece with a typical diameter in a range of 12-16 inches and a height in a range of 30-48 inches. Much of this volume is empty and is used only for airflow. An item of this size is very bulky and cumbersome to handle, especially when packaged. In addition, the costs associated with shipping such a large, cumbersome, air-filled item can be excessive.
- In view of these drawbacks of conventional central vacuum power units, there is a strong need for a central vacuum power unit that could be packaged and shipped in a more compact and efficient manner.
- The present invention provides a nested packaging design and method for compact and efficient packaging of a power unit of a central vacuum cleaner. The power unit is divided into components or sections that can be disassembled and nested together for shipping and handling in a much smaller configuration. The disassembled, nested and packaged central vacuum power unit of the present invention is approximately half the size of the assembled unit. Shipping, handling and storage issues associated with conventional central vacuum cleaners are minimized or eliminated by the present invention.
- Accordingly, one embodiment of the invention is a central vacuum power unit comprising at least two functional and separate components. The components are attached in a stacked assembly during operation, and are detachable for configuration in a nested assembly during non-operation.
- Another embodiment of the invention is a nested packaging assembly for a central vacuum power unit. The assembly includes a cylindrical body module, a dust bucket nested within the body module, and a motor module nested within the dust bucket.
- Another embodiment of the invention is a method for packaging a central vacuum cleaner for transit or storage. At least two functional components of the vacuum cleaner are detached and nested within each other.
- Another embodiment of the invention is a method for operation of a central vacuum cleaner. The method comprises stacking a motor module above a body module, and the body module above a dust bucket, for vacuuming operations; and nesting the motor module within the dust bucket, and the dust bucket within the body module, for shipment or storage.
- Other features and advantages of the invention will be apparent from the following detailed description, taken in conjunction with the accompanying drawings which illustrate, by way of example, various features of embodiments of the invention,

FIG. 1 is a front view of an assembled centralvacuum power unit 50 according to the present invention.Power unit 50 may be used in household or commercial applications.Power unit 50 has a cylindrical configuration, is approximately 12-16 inches in diameter and, when assembled, is approximately 40 inches in height.Power unit 50 comprises three separate, functional sections or components: acentral body module 20, adust bucket 30 attached belowbody module 20 and amotor module 40 attached abovebody module 20. - Since the components are essentially stacked one on top of the other, the assembled configuration of
FIGS. 1-3 is referred to as the “stacked assembly”. -
Body module 20 is the largest section of the power unit and is essentially a large cylinder or canister. As will be described below, the large empty volume ofbody module 20 is necessary to hold and accommodate inflation and deflation of a vacuum filter bag ormedia 15 attached therein. It comprises an upper metal tube orwrapper 24 and alower skirt 25. Avacuum inlet 10 andutility port 11 are formed in, or defined by,skirt 25.Slide latches 21 are attached to, or formed integrally with, skirt 25 for holdingdust bucket 30 in place. In one embodiment,skirt 25 comprises two plastic, semi-circular components. Filter 15 (FIGS. 2-3 ) is attached within the interior ofbody module 20 abovevacuum inlet 10 andutility port 11 and filters dust, debris, etc. from the air flow enteringpower unit 50 throughinlet 10 and/orport 11. -
Motor module 40 is attached abovebody module 20. For ease of repair and replacement, all factory serviceable electronics and active mechanical components are housed withinmodule 40, including avacuum motor 17 and associated electrical controls and mounting hardware.Motor 17 is a conventional motor mounted and configured for operation withinmodule 40 in a manner familiar to those of ordinary skill in the art.User interface 41 is formed on the exterior ofmodule 40, and may include items such as an on/off switch, a debris level indicator, a motor service indicator, a motor power indicator and a vacuum level indicator. Motor module also includes an air passage and an exhaust port to exhaust air flowing upward frombody module 20. A detachable or integrally-formedmuffler 18 is typically provided on the exterior ofmodule 40 around the exhaust port. Asecondary filter 16 may also be provided inmotor module 40. -
Dust bucket 30 is attached belowbody module 20 to capture and accumulate dirt, debris, etc. that is removed byfilter 15 from the air flowing throughpower unit 50.Dust bucket 30 may be attached and configured in alternative ways that are known or will be apparent to those of skill in the art. Importantly, where afilter 15 is interposed between anair inlet 10 andoutlet 18, thedust bucket 30 should be configured and oriented in a manner that captures dirt and debris thatfilter 15 removes from the airflow. - Central
vacuum power unit 50 is typically assembled on site at the time of installation. When completely assembled,body module 20 may be attached or hung on a wall or other structure, withmotor module 40 attached abovebody module 20 anddust bucket 30 attached belowbody module 20. This design assures that, when assembled on site, all modules are properly aligned to compress gaskets that are integral to the modules and prevent or minimize leakage during operation ofunit 50. - During operation of
motor 17, as shown inFIG. 2 , vacuumed debris and air entersbody module 20 ofpower unit 50 atinlet 10. Alternatively, for local applications, vacuumed debris and air may enterpower unit 50 via a flexible hose and tool attached atutility port 11. The air flows in an upward direction frominlet 10 and/orport 11 to exhaustport 18 inmotor module 40.Filter 15, interposed therebetween, inflates and filters dust and debris from the airflow and keeps it in the space belowfilter 15.Secondary filter 16 is mounted abovefilter media 15 and provides additional filtering and acts as a backup in the event that filtermedia 15 fails, or debris, etc. gains access to the space abovefilter 15 during installation, maintenance, inspection, etc. ofpower unit 50. Filtered air is exhausted frompower unit 50 viamuffler 18. - When
motor 17 is turned off, as shown inFIG. 3 , filter 15 deflates and collapses into the lower portion ofbody module 20 and partially intodust bucket 30. The deflation and collapse offilter 15 may be assisted by an integral weight. During this motion, dust and debris attached to the lower surface offilter 15 detaches and falls intodust bucket 30, where it is collected and held. - Two slide latches 21
couple dust bucket 30 tobody module 20. Whendust bucket 30 becomes full of dust and debris, latch levers 21 formed on the upper portions oflatches 21 are rotated down, thereby lowering latch hooks 23 formed on the lower portions oflatches 21. Withhooks 23 lowered,bucket 30 can be removed and emptied of the dust and debris collected therein. Once emptied,bucket 30 is reattached by placing it onhooks 23 and rotating latch levers 22 upward to raisehooks 23 andsecure bucket 30 belowbody module 20. - The components of
power unit 50 are easily disassembled and nested together for storage or packaging and shipping. As shown inFIG. 4 ,dust bucket 30 andmotor module 40 are easily detached fromcentral body module 20. The three components are then oriented as shown inFIG. 5 to compactly nest together. Essentially,motor module 40 is nested withindust bucket 30, and these two components are in turn nested withinbody module 40. -
Motor module 40, which is the heaviest and most dense component, is placed at the bottom in an upright orientation. Next,dust bucket 30 is flipped upside down and placed overmotor module 40, which nests within the hollow interior ofbucket 30. Lastly,body module 20 is placed over and aroundbucket 30 in an upright orientation to yield the compactly nested configuration illustrated inFIG. 6 . Latch hooks 23 may be secured underneathmotor module 40 anddust bucket 30, and rotated upward, to cinch and secure the three components together. - The nested packaging configuration illustrated in
FIG. 6 , referred to as the “nested assembly”, is much more compact than that of conventional power units, and permits a significant reduction in packaging size and bulk. Preferably, it occupies approximately half or less of the space of the assembled, stacked assembly ofFIGS. 1-3 . - Other components and accessories associated with
power unit 50, such as thedetached muffler 18, associated mounting hardware, wall mounting plates and pipe/hose attachment items, can be placed inside ofbody module 20 on top ofdust bucket 30. In this manner, they do not cause an increase in the packaging size. Other packaging items such as plastic bags, cardboard and foam inserts, etc., can be added to the stack to prevent damage during shipping. - The particular embodiments of the invention described in this document should be considered illustrative, rather than restrictive. Modification to the described embodiments may be made without departing from the spirit of the invention as defined by the following claims.
