BRIEF DESCRIPTION OF THE DRAWINGS The above and other objectives of the invention; -will-; become apparent from the followingdescriptiontakenw in connection with the accompanying. drawings,
wherein:
FIG. 1 is a schematic illustration of one embodiment on washers and other appliances. Therefore, details ofthis=componentzare omitted here.
IH'zfiCCOl'dQ-I'ICC' withthis invention an automatic ash removaLsystem-isprovided for removing any residual ashzwhich remainsafter an incineration cycle has been completed. Ithas beenfound that the ash resulting fromefficientandcomplete burning in an incinerator ofithe;type,for example,- as shown-in the aforementionedicopendingrapplication, will be a very light, dry, particulate matter, biologically inert and nonodorous.
This residueaccrues in extremely small amounts due to the extremely efficient combustion of the trash in the chamber l2iaszwell asof combustion products therefrom. v
Theash removal system shown in FIG. 1 includes an airzcompressor20 similar, for example, to those used in common'vacuum cleaners. However, other air compressors may be utilized with this invention. Compressor'20 is connected to one end of a pipe or conduit 22 which has itsother end extending through the wall of thev incinerator.10 and terminating within chamber 12 Ma position where the air being'forced into the chamberby thecompressor will stirup the residual dustlike ash and suspend it in a desired circulation pattern. Also mote from pipe 22 is one end of a second pipe 24 which provides means for exhausting the ash-laden air. Exhaust pipe '24 -is connected at its other end, through a closed container 26iwhich-is coupled to the compressor 2.0..1This pipe .24 and container 26 become a suctionv line-for exhaust of theair from chamberl2. Within container 26 is ardust-impervious bag 28 which has one end removablyconnected to the pipe 24 50 that the ash-ladeniair from-chamber 12 .will pass into the bag 28' which will filter out the ash while permitting the cleaned air to. pass back-into thecompressor 20. The container 28is, of course, provided with anysuitable access means (not shown) whereby bags 28 may be removed and replaced when filled.
From the foregoing it will be apparent that efficient is completed, a timer of thermostat, which is set to determine a cooling period sufficient to allow the trash chamber 12 to reach close to ambient temperature, activates the compressor 20. This forces air through pipe 22 into chamber 12, causing it to circulate in the desired pattern which results in ash residue being picked up in the air stream, which ash-laden air is then suctioned out through pipe 24 into bag 28 where the ash is filtered out, and the clean air passed back to the compressor 20 for recirculation. AFter several passes, the trash chamber is essentially cleaned of residue, and at the end of the preselected time period the timer in control l6 shuts off the compressor. No personal contact with the ash, or with the incinerator, is required at any time in connection with cleaning other than to replace the bag when desired.
In the embodiment shown in FIG. 2, a suction pipe 30 has one end connected to the incinerator chamber 12, similarly to pipe 24 in FIG. 1, and the other end is connected into the upper end of a cylcone filter 32. The cyclone filter 32 is a vertically elongated container having a narrow lower neck or end portion 34 to which is secured one end of a disposal bag 36. Bag 36 is, of course, impervious to dust and may, if desired, be impervious to air. The end of pipe 30 is introduced into the cyclone filter tangential to the inner surface of the filter, as shown best in FIG. 3, so that incoming ashladen air will be made to circulate within the filter, as shown by the arrows in FIG. 3. The ash or dust in the air will spiral downwardly and eventually will deposit in the bag 36.
A compressor 20 will create the flow of air into the incinerator chamber 12 through pipe 22, as in the FIG. 1 embodiment. However, an additional coupling pipe 38 is connected at one end to the compressor 20 and has its other end inserted within the filter 32. Pipe 38 is a suction line which serves to draw the filtered air out of the cyclone filter 32 back to the compressor for recirculation. This system provides an extremely efiicient way of cleaning the incinerator. Of course, the control mechanism 16, shown in FIG. 1, also will be used with this embodiment of the invention. The only manual effort required with this system is to periodically empty or replace the bag 36.
The further embodiment of the invention illustrated in FIG. 4 includes the incinerator l0, compressor 20, pipes 30, 38 and 22, and cyclone filter 32, as in the FIG. 2 embodiment. However, instead of utilizing a disposal bag, this system embodies a pipe 40 which is connected by nut 42 or any other suitable means to the lower end portion 34 of the cyclone filter 32. The other end of pipe 40 is connectd by suitable means 44' to a drain system 46. The house water system is connected by, a pipe 48 and valve 50 into the upper end portion of filter 32 whereby,.when the valve 50 is open, water will be permitted to enter the filter 32 to flush the residual ash dust down the drain 46.
The valve 50 will, of course, be connected to the control system 16 (FIG. .1) so that it will be opened only during a cleaning cycle. It has been found that the ash produced by the described type of incinerator does not agglomerate and will not collect in traps or drain pipes so as to cause clogging. Disposal into septic tanks is also feasible. In this system no manual effort whatsoever is required in connection with incinerator clearimg.
From the foregoing it will be apparent that all of the objectives of this invention have been accomplished by the automatic incinerator cleaning systems shown and described. It is to be understood, however, that various changes in the structures shown and described may be made by those skilled in the art without departing from the spirit of the invention as expressed in the accompanying claims.
