Field of the Invention
The present disclosure relates to a system and apparatus for compacting trash in a household application.
Description of the Related Art
There has long been an interest in reducing landfill volume. Methods currently in use to accomplish this goal include reducing the amount of trash generated, increasing recycling of materials that may be recycled, and compressing trash volume.
U.S. Pat. No. 6,135,637 discloses a compressible trash bag having a series of vertical air slots made up of fine perforations on the upper portions of both walls that break open from stress of compression to allow excess air inside the bag to discharge to the outside atmosphere.
U.S. Pat. No. 5,690,248 discloses a nested bag assembly for containing material requiring handling and compaction that reduces the risk of rupture during compaction.
JP08002604, Chinese Patent Appl. Publ. No. 2,579,843, United Kingdom Patent Appl. Publ. No. 2,447,612, and United Kingdom Patent Appl. Publ. No. 2,470,578 disclose systems and apparatuses that use inflatable air bags to compact trash.
While the above efforts have attempted to solve various problems with respect to trash compacting, there remains a need for a simple, low maintenance, inexpensive trash compacting system and apparatus that is suitable for home use.
A trash compacting apparatus comprising a container, an air pump, one or more inflatable air bladders, a controller unit, and an interface unit is disclosed herein. The apparatus may further comprise an air distributor. The apparatus may operate as a standard trash container and may further comprise a lid. The apparatus may be operated by the user or by a programmable controller unit to inflate the air bladders, thereby compressing trash contained within the apparatus and reducing the total volume of the trash.
A trash compacting apparatus comprising a container, an air pump, one or more inflatable air bladders, a controller unit, and an interface unit is disclosed herein. The apparatus may further comprise an air distributor, a load plate, a load sensor, and a pressure sensor. The apparatus may operate as a standard trash container and may further comprise a lid. The apparatus may be operated by the user or by a programmable controller unit to inflate the air bladders, thereby compressing trash contained within the apparatus and reducing the total volume of the trash.
Design
Some embodiments of the compacting trash apparatus disclosed herein generally mimic ordinary trash containers, and comprise a container for holding trash, a base, an air pump, air bladders, an air distributor, a load plate, a load sensor, and a pressure sensor. Some embodiments may further comprise a lid. The trash compacting apparatus may use an external power source, such as electricity or battery power. In some embodiments, the trash compacting apparatus may be electrically powered and further comprise an electrical pump. The electrical pump inflates air bladders inside the container, thereby compressing the trash and reducing the total trash volume. This allows the user to add more trash into the container. In some embodiments, the trash compacting apparatus may be powered by a pneumatic system, wherein the apparatus may be connected to an external air pump and may use a series of valves to control the pressure in the air bladders.
In some embodiments, the air bladders may be shaped as circular trapezoids, wherein multiple air bladders may cover the circumference of a circular container. Each air bladder may include a nozzle that plugs into an air distributor, and may include a metallic or polymer layer to protect the air bladder from being punctured during normal operation and to improve its durability.
A primary air pump may be used to inflate the air bladders, wherein the primary air pump pumps air into the air bladder, increasing the pressure within each air bladder and causing each air bladder to expand. In some embodiments, an external air pump or centralized pneumatic system may be employed.
In some embodiments, each air bladder may further comprise a valve that may be closed when the air bladder is inflated and may be opened to the atmosphere to release air on account of the natural pressure difference between the air bladder and the atmosphere.
In some embodiments, a secondary air pump may also be used to deflate the air bladders after use to compact trash, wherein the secondary air pump removes air from the air bladders and vents it into the atmosphere and wherein the secondary air pump may be the same air pump as the primary air pump or may alternatively be a different air pump than the primary air pump. In some embodiments, a vacuum pump may be used to deflate the air bladders after use to compact trash.
In some embodiments, an air distributor may be used to distribute air between separate air bladders, allowing the apparatus to maintain approximately equal air pressure in all the air bladders and thereby preventing a given air bladder from exceeding its pressure limit. In some circumstances, this may promote more efficient operation of the system by adjusting for trash objects that may be limiting a specific air bladder from inflating by inflating surrounding air bladders instead of the air bladder that has been obstructed by a trash object.
In some embodiments, a pressure sensor may be used to measure the air pressure in the trash compacting apparatus to regulate and control the air pressure in the system.
In some embodiments, a load sensor may be used to measure the weight of trash contained in the container to determine whether the weight has reached or exceeded a predetermined threshold.
The container may be configured to use disposable or reusable garbage bags.
In some embodiments, a controller unit may control the timing of compression, air pump power consumption, and other system parameters that promote the successful and efficient operation of the trash compacting apparatus. The controller unit may also present information to the user via an interface, such as a visual display, or an auditory, tactile, or other interface. The controller unit may be connected to the Internet to present information to the user via electronic mail or one or more other forms of electronic communication. The controller unit may also receive information from the user to determine how and when to operate the system.
Operation
In some embodiments, all the air bladders are deflated and deployed toward the sides of the container to allow for maximum volume for trash input. After trash is inserted into the container, the user may close and lock the lid and activate the trash compacting apparatus. This process may also be automated, for example at a certain time of day. In some embodiments, the lid may have an automatic locking system to improve safety and functionality. Upon completion of trash compaction, the air bladders may be deflated again as described above, and the lid may be unlocked.
The disclosure and examples above are intended to be illustrative and are not intended to limit or otherwise restrict the invention. Numerous variations and modifications will become apparent to those skilled in the art upon full appreciation of the above disclosure.
