Title: Odorless waste disposer unit

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a divisional of application Ser. No. 14/967,277 the title of which is Floating methanation system. 
    
    
     BACKGROUND OF THE INVENTION 
     The invention is in the technical field of waste disposer units, specifically in the field of mechanisms for reducing food waste. 
     Usually, when a waste disposer unit is installed, food waste is fed with water into this waste disposer unit stored under a kitchen sink. The food waste is grinded within the disposer in order to reduce it so that it can be flushed to the plumbing system of a residence or commercial establishment. 
     One of the problems that seem related to the current state of technology in this domain is the odor emanating. 
     SUMMARY OF THE INVENTION 
     The waste disposer unit claimed in this application addresses the problem of odor emanating from the sink by flooding the grinding chamber with water and using a swivel plug that allows the retention of water in the grinding chamber and creates a partition with clear water from the tap to isolate dirty water remaining in the grinding chamber. 
     The proposed unit has a grinding apparatus made of cutting blades, placed in front of a spherical grid, that segment the matter by tearing it up several times while it swirls in the water. The spherical grid serves as a barrier preventing large objects from going through.

     DESCRIPTION OF THE INVENTION 
     Referring to the drawings in greater detail and by reference characters thereto, there is illustrated an odorless waste disposer unit  300 . 
     In order to prevent the proliferation and emanation of disagreeable odors and to achieve the odorless grinding of waste material, the principle consists of the retention of water flooding the chopping chamber  301 , establishing a ring of clean water around a swivel plug  302  from the ultimate flow of the tap. The swivel plug  302  allows the creation of a partition with clear water from the tap serving to isolate the dirty water remaining in the grinding chamber. These elements are illustrated in  FIGS. 17A and 17C . 
     The siphon that maintains the water level is equipped with a bypass valve  303  (seen in  FIG. 17B ) that allows complete drainage when maintenance is required. The swivel plug  302  can be tilted and removed (seen in  FIG. 17C ) to facilitate the passing through of large pieces of waste. A sealing cover plug  304  ( FIG. 17D ) can be added over when one wishes to fill the sink. 
     A float  305  (shown in  FIG. 17C ) can be used to activate the mechanism when water accumulates in the sink. Because the chopping elements in the grinding chamber  301  make a fence, holding the not yet chopped matter against it, the water flowing from the tap may then rise in level and lift the float  305  that will engage the grinding motion to reduce that matter. When the matter has been evacuated from the grinding chamber  301 , the water will be free to rest to its proper level, relieving the contact from the float and stopping the motion. In this way, we have an automation potential. 
     The waste disposer unit segments the objects by slicing them, or by tearing them up several times while they swirl in the water inside the chopping chamber  301 . This process of cutting and tearing continues until the matter is reduced to fragments small enough to go through the openings in a spherical grid  306  (shown in  FIG. 17H  and  FIG. 17I ). 
     Behind the spherical grid  306 , there may be one or several back blades  307  (seen in  FIG. 17I ); their cutting edges segment the particles coming through the openings of the grid  306 . The tail edges of the blades  307  rise apart as a propeller pitch to create a vortex to pump the material when necessary. 
     This waste disposer unit can be fabricated in different sizes and adapted to commercial and industrial uses. A few possible embodiments are illustrated in  FIGS. 17E, 17F, and 17G . 
     As can be seen in  FIG. 17E , the waste disposer unit can be installed inside a recipient big enough to contain large solid matter to be grinded. Since these large objects swirl in the recipient by the impact, the turbulence and the vortex coming from the rotation of the back blades  307 , they can be torn up and shredded into particles. 
       FIG. 17G  shows another possible embodiment for industrial use. In this case, the invention can be used to extract decanted layers of sediments. 
     It will be understood that the above described embodiments are for purposes of illustration only, and that changes or modifications may be made thereto without departing from the spirit and scope of the invention.
