CLAIM OF PRIORITY 
       [0001]    This application claims priority to U.S. application Ser. No. 62/169,845 filed on Jun. 2, 2015, the contents of which is herein fully incorporated by reference in its entirety. 
     
    
     FIELD OF THE EMBODIMENTS 
       [0002]    The field of the invention and its embodiments relate to an apparatus that is capable of removing frozen and/or semi-frozen material from a property, treating the material, and returning it to the environment. In particular, the present invention permits the removal of ice, snow, slush, and the like from the environment and reduces it to its liquid form thereby cleansing the environment of such material. 
       BACKGROUND OF THE EMBODIMENTS 
       [0003]    When it snows, various municipalities, communities, airports, and the like spring into action to help clear the fallen snow. By clearing the snow in an expeditious manner, one can reduce disruptions to travel and other hazards that commonly plague snow fallen areas. This is especially important for areas where the snow and ice may accumulate rapidly and remain for a long period of time. 
         [0004]    Typically snow removal methods involve plowing and/or relocating the snow and ice to a less populated or other designated area, where it is then allowed to remain to melt naturally. Dump trucks, front end loaders, and other heavy equipment are often used to help assist in this removal process. However, this method of removal has its pitfalls. For example, the accumulated snow and ice remains and it often piled in areas that may take months to melt long after all other snow and ice has melted. Additionally, in populated areas, this snow takes up precious space that could be otherwise utilized. 
         [0005]    Another way snow and ice may be removed is through the use and application of chemicals to the ice and snow that disrupts the intermolecular bonds contained therein causing the snow and ice to melt. However, this cannot be performed on a grand scale and can be quite expensive. Further, there is a latency period for the effects of the applied chemicals to be seen. Even still, if it is sufficiently cold outside, the chemicals may be rendered ineffective. 
         [0006]    Thus, some entities have gone to using snow removal machines that receive collected snow in a receptacle and apply hot gases or water to the snow and ice in order to melt it. A disadvantage to such apparatus currently on the market is that they are not easily movable and are typically placed in only places that receives vast quantities of snow and high foot traffic such as a parking lot. In some instances, such apparatus requires a sewer hookup in order to get rid of the melted snow and ice. 
         [0007]    There is a need for an apparatus that is self-sufficient and portable that can effectively melt ice and snow. It is desirable to have such an apparatus be able to quickly process the snow and ice and return it to the environment. Further, such an apparatus can be brought to the snow and ice rather than have to snow and ice brought to it. The present invention meets and exceeds these objectives. 
         [0008]    Review of related technology: 
         [0009]    U.S. Pat. No. 7,958,656 pertains to a snow melter that may be used to melt snow. The snow melter includes a dump tank for receiving a quantity of snow to be melted. The melter also includes a melt tank and a heat exchanger. The melt tank separate from the dump tank. The heat exchanger heats the water in the melt tank. Water heated by the melt tank is allowed to flow from the melt tank into the dump tank to melt the snow in the dump tank. Doors may also be added to the dump tank to facilitate the removal of debris from the dump tank after use. Further, the dump tank may also have an inclinable floor to further facilitate the removal of debris from the dump tank after use. 
         [0010]    U.S. Pat. No. 4,615,129 pertains to a mobile snow-disposal unit having a vehicle including a sealable snow-collection receptacle having a water-holding internal compartment and an engine for propelling the vehicle utilizes a vacuum pump for lowering the internal pressure of the receptacle, when sealed, and a heat exchange system for routing waste heat from the engine to the internal compartment. By lowering the internal pressure of the receptacle so that the boiling temperature of water held by the internal compartment is about equal to the temperature of the waste heat entering the internal compartment, water held within the internal compartment is converted to steam for readily melting the collected snow. 
         [0011]    U.S. Pat. No. 4,164,820 pertains to a fluid containing insulated tank is mounted on a vehicle chassis having an engine driving a hydraulic system and an electric energy generating unit. The roadway cleaning apparatus, including housing contained screw conveyors, is mounted transversely of the forward end of the vehicle chassis for discharging snow and roadway debris through discharge tubes into the tank through an inlet port opened and closed by a hydraulically operated inlet port opening and closing door. Electric resistance heaters, contained by the tank and mounted thereon, melts snow and heats fluid and air contained by the tank. An agitator within the tank forms a slurry of the contents. 
         [0012]    U.S. Patent Application 2010/0313451 pertains to a snow removal vehicle that has an enclosed snow melting chamber provided with a plurality of high pressure steam jets which are connected to one or more steam generators. The enclosed snow melting chamber has a water collecting reservoir in a lower portion thereof below a bottom wall of the snow melting chamber. The bottom wall has passages to channel water from the snow melting chamber to the water collecting reservoir. The vehicle body has a front entry opening communicating with the snow melting chamber and an auger screw is mounted in the front entry opening to eject snow inside a forward end of the snow melting chamber. Snow propelling wheels are secured along at least a front end portion of the snow melting chamber to propel snow ejected from the auger along the snow melting chamber for contact by the high pressure steam to melt the snow. An outlet evacuating valve is provided to evacuate water collected in the water collecting reservoir. The vehicle may also be equipped with a hopper chute for use in a stationary mode to melt snow dumped in the chute. 
         [0013]    Various devices are known in the art. However, their structure and means of operation are substantially different from the present disclosure. The other inventions fail to solve all the problems taught by the present disclosure. At least one embodiment of this invention is presented in the drawings below and will be described in more detail herein.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0032]    The preferred embodiments of the present invention will now be described with reference to the drawings. Identical elements in the various figures are identified with the same reference numerals. 
         [0033]    Reference will now be made in detail to each embodiment of the present invention. Such embodiments are provided by way of explanation of the present invention, which is not intended to be limited thereto. In fact, those of ordinary skill in the art may appreciate upon reading the present specification and viewing the present drawings that various modifications and variations can be made thereto. 
         [0034]    Referring now to  FIG. 1 , there is a perspective view of an embodiment of the apparatus  100 . Generally, the apparatus  100  has a body  105  having a front end and a back end with a container  110  thereon, an access door  102 , an outlet  112 , wheels  104 , a control system  108 , sensors  136 , and a suction mechanism  106 . The exact appearance of the apparatus  100  may vary and there may be different locations for the parts shown and others not explicitly described herein. The apparatus  100  may take the form of a vehicle, namely an autonomous vehicle, and may be of generally a solid construction albeit for the access door  102 . This is due to the fact, as noted, that it is preferable to have the apparatus  100  operate autonomously thereby removing the need for abundant interior access and controls. 
         [0035]    The wheels  104  may each be capable of independently rotating and turning in relation to one another thereby allowing the apparatus  100  to reach virtually any area the environment to be treated. Such an environment may include roadways, parking lots, yards, sidewalks, and the like or any combination thereof. Further, the wheels  104  may have treading to help it grip and maneuver through a variety of terrains. In some instances, it may be appropriate to have the wheels  104  bear studs, chains, spikes, or other suitable mechanisms to provide traction on icy and otherwise slippery surfaces. 
         [0036]    The sensors  136  may be proximity sensors that are capable of supplying information to the apparatus  100 . The apparatus  100  may have a global positioning system (GPS), as described further below, that is used for navigational purposes to define its geographic boundary for operation. However, the GPS cannot take into account various obstacles including temporary obstacles such as an automobile. Certain sensors may be selected to enable the apparatus to readily distinguish between a buildup of snow and an obstacle that is blocking its path. 
         [0037]    Thus, the sensors  136  can determine through a variety of mechanisms known in the art whether there is an obstacle and the proper procedure to take to avoid the obstacle. In some instances, the apparatus  100  will simply avoid or go around the obstacle, whereas in other instances the apparatus  100  will re-route itself and return later to see if the obstacle has been cleared. The sensors  136  may be disposed on any surface or combination of surface of the apparatus  100   
         [0038]    In  FIG. 2 , there is a side view of the apparatus  100 . Here, shown is the access door  102 , handle  118 , control system  108 , wheels  104 , suction mechanism  106 , sensors  136 , storage  138 , and outlet  112 . The control system  108  may comprise at least an input  114  and a display  116 . 
         [0039]    The input  114  is preferably a touch sensitive keyboard which enables the input of commands and other directives into the apparatus  100 . Navigational mechanisms on the input  114  may further provide assistance in making adjustments to the apparatus  100 . The display  116  may be a liquid crystal display (LCD) or other suitable interface for communicating the operations and settings of the apparatus  100 . An electronic device such as a lap top computer, desktop computer, multimedia player, gaming system, smart phone, smart watch, and the like or any combination thereof. The electronic device may be capable of communicating with the control system  108  thereby enabling remote monitoring and/or control of the apparatus  100  via the electronic device. 
         [0040]    The storage  138  may be individual inlets or drawers within the body  105  of the apparatus  100 . The storage  138  may store any necessary materials for the apparatus  100  including the aforementioned chains, etc. to be used for traction purposes. Other items such as snow/ice scraping and cleaning tools may be stored therein until needed. 
         [0041]      FIG. 3  demonstrates at least some of the internal components of the apparatus  100  via a cutaway side view of the apparatus  100 . The suction mechanism  106  resides in the lower portion of the apparatus  100 . Namely, the suction mechanism  106  provides a conical or similarly shaped extension that extends below the main structure of the apparatus. The suction mechanism  106  preferably uses a motor to and an air pump to generate a partial vacuum thereby enabling frozen and/or semi-frozen  120  to be brought into the apparatus  100 . 
         [0042]    In some embodiments there are additional suction mechanisms positioned around the apparatus  100 . For example, a suction mechanism may exist on the roof structure or on top of the apparatus  100 . Such a mechanism may have a sensory device that is capable of recognizing snow fall thereby enabling it to capture snow before it makes ground fall. In some embodiments, the roof top suction mechanism is activated by information received from or a built in wireless weather device, such as an application, that provides information about the current weather state of the environment to the apparatus  100 . 
         [0043]    In other embodiments, other appropriate mechanisms and methods for creating suction may also be employed. In some instances, the suction mechanism  106  is capable of being articulated to collect the frozen and/or semi-frozen material  120 . This may be used to further compensate for differences in elevation of the landscape. The apparatus  100  may be capable of adjusting the articulation of the suction mechanism  106  as it progresses through its route or course. 
         [0044]    In addition, a plowing mechanism may be required to disperse some level of ice and snow to permit travel of the apparatus through an environment. The plow may be articulating to change the amount of snow plowed in order to provide proper clearance and ensure enough material is suctioned via the suctioning mechanism  106 . 
         [0045]    Internally, there is at least one compartment and preferably two compartments. When the frozen and/or semi-frozen material  120  enters the first compartment  113 , it is subjected to a heating element  130  which begins to melt the material. A first hinged door  137  prevents the material (both in current and processed form) from exiting the first compartment  113  through the same opening it entered via the suction mechanism  106 . The heating element  130  may be any type of heating element including ceramic heaters, electrical lighting, composite heaters, and the like or combinations thereof. Most embodiments would provide some form of electric based heating. 
         [0046]    In other embodiments, there are solar panels that can supply electrical energy to the thermally regulated heaters. This allows the apparatus  100  to expend less electrical energy than needed. However, in such embodiments, any electrical battery may be recharged through a regenerative braking process. 
         [0047]    The heating elements  130  may be arranged in various formats including but not limited to linear arrangements, tiered arrangements, intermittent arrangements, and the like or any combination thereof. As the frozen and/or semi-frozen material  120  begins to melt it passes into the second compartment  115  via a second hinged door  137 . In some embodiments, this second hinged door may be a screen door that allows liquid to pass therethrough while preventing larger debris from passing into this second compartment  115 . In the second compartment  115  the frozen and/or semi-frozen material  120  continues to be heated until it is completely melted. The first compartment  113  and the second compartment  115  are both graded in a way that directs the processed flow to a transport system  131 . 
         [0048]    The transport system  131  is essentially a piping network that takes the processed material  128  from the compartments to the outlet  112 . The transport system  131  may be pressurized in order to allow for the adequate dispersal of the processed material  128  through the outlet  112 . The transport system  131  may have mechanisms in place to help screen the processed flow to remove and debris not already captured by the system in general. For example, the hinged doors  137  may have a ridge underneath them to trap larger material while letting the liquid flow over the top in addition to the screen features noted above. Further, when the frozen and/or semi-frozen material  120  is first brought in by the suction mechanism  106  there may be a catch for heavier materials that would fall off from the suction flow before even reaching the first compartment  113 . 
         [0049]    Once the processed material  128  reaches the outlet  112 , fluid dispersal mechanisms  126  are positioned a varying configurations to return the processed material  128  to the environment. The outlet  112  may simply deposit the processed material  128  immediately under the apparatus  100 . In some cases, the processed material  128  may be directed away from this area and be dispensed outwards from the apparatus  100 . In other embodiments, a dumping mechanism may be employed to remove either some or all of the processed material from the apparatus. This would enable the container to be raised at an angle allowing the processed material to flow out therefrom. 
         [0050]    In some embodiments the processed material  128  has a chemical agent added at some point along the process. Such a chemical agent may be liquid de-icers known in the art that prevents the processed material from refreezing. Further, solid form de-icers may be added via the outlet  112  to the surrounding environment. 
         [0051]    The apparatus  100  and its components operates by way of an energy source  134  which may manifest itself as a combustion engine and/or battery operated motor and/or batteries. This energy source should provide ample energy to run any and all of the systems associated with the apparatus  100 . 
         [0052]    Referring now to  FIG. 4 , there is an exemplary screen that a user may encounter upon accessing the display  116  (see  FIG. 2 ) that enables the user to modify and otherwise manipulate the apparatus. 
         [0053]    Here, the screen  200  has a display screen  240 . Located on the display screen  240  are a number of selectable icons which may direct the user to a secondary screen(s) or may open up a menu for selections to be made. The screen may be touch sensitive and support touchscreen technologies. An input  114  (see  FIG. 2 ) may also assist the user in navigating and otherwise interacting with the apparatus. The shown icons are meant to be exemplary only and the actual icons may be the same or different as described. Further, the functionality and menu tree associated with each icon may be the same or different and some functionality described under one icon may actually reside under another. As noted, this screen may also be reached from an electronic device employing a web or mobile based application and providing the same functionality and control. 
         [0054]    The set course  205  enables a user to modify, create, delete, or otherwise makes changes to a course setting of the apparatus. The course may be set initially via coordinates, geo-fencing, or the like or some combination thereof. In some instances, one may have to manually guide the apparatus through the desired course in order to for the apparatus to “learn” the course. Once the course is set, is can be saved in a system memory and be modified at a future time and date as needed. Multiple course profiles may be capable of being stored thus enabling quick one touch selection of a desired area for the apparatus to treat. The set course feature operates in conjunction with the sensors  136  discussed in  FIG. 1 . This enables complete automation of the apparatus thereby saving an individual or municipality time, effort, and expense. The apparatus  100  can simply be deployed as needed and complete the task at hand. The modify settings  210  can be used to modify most any general settings as applicable to 
         [0055]    the apparatus. This may include the particular treatment(s) to be applied to the frozen and/or semi-frozen material, the amount of suction generated by the suction mechanism, the speed at which the apparatus is to travel, sensitivity settings, and the like or any combination thereof. Some such functionality has been otherwise discussed herein and other functionality may be prescribed that is not specifically contemplated herein but is contained under the purview of this invention. 
         [0056]    The set schedule  215  allows for a fixed schedule to be set for the apparatus to operate under. Thus, a real time clock, stored in the on-board programming, may enable the apparatus to treat certain areas at certain dates and times dependent on the scheduled settings. Course selections may be selected from under this setting to allow for importing of saved courses enabling certain courses to be run during a certain time or date. 
         [0057]    The check status  220  enables the user to graphically view any of the systems in order inspect the apparatus as a whole to ensure that the apparatus is functioning correctly. Various system readouts such as fluid levels, fuel or battery levels, temperatures, and the like can be viewed and modified as need be. 
         [0058]    The maintenance  225  enables warnings or alerts to be broadcast to the user to signify that an action needs to be taken in order to ensure the proper functioning of the apparatus. Such warnings may include a lack of required fluids, a caught or stuck component, a non-operative component, or other malfunction recognized by the system. 
         [0059]    The open access door  230  enables any locking mechanism to be released enabling the access door to be opened. This provides access to the interior of the apparatus but also can prevent unintentional opening of the access door which could result in injury or decreased performance by the apparatus (i.e. loss of suction). 
         [0060]    The start  235  enables the apparatus to start running a specific protocol in conjunction with the aforementioned settings, courses, etc. 
         [0061]    Referring now to  FIGS. 5-6 , there is another embodiment of the present invention. Here, the embodiment is shown in a perspective view as well as a cutaway side view, respectively, showing a possible configuration of the internals of the embodiment. This embodiment may be intended to be a vehicle that can be remotely controlled, much like a drone, and be used to automatically, or under remote guidance, clear snow falls, ice, slush, and effectively dispose of the said materials. This device may be of particularly assistance the elderly or infirm in urban environments. Further, such a device may permit areas with large snow falls to remove the snow without simply piling it up. 
         [0062]    Generally, the apparatus  100  has a front end  101 , back end  103 , wheels  104 , camera/directional system  146 , conveyor  142 , tiller/blade  144 , piping  160 , compartment  162 , vents  148 , nozzles  140 , body  105 , heater  158 , chute  152 , and supports  156 . 
         [0063]    In practice, as the blade  144  rotates, it picks up snow/slush/ice/etc. off the sidewalk, driveway, or other ground surface and loads it on to a conveyer  142 . The collected material is then moved up towards the top of the conveyer  142  by the rotary action of the conveyor  142 . When the material reaches the top of the conveyer  142 , it falls from the conveyor  142  into an internal compartment  162  having a piping system  160 . The piping system  160  is heated by an internally circulating fluid and to begin melting the material. In addition, there is a set of nozzles  140  that direct steam or heated liquids at the snow, both melting the material and also vaporizing some of it into the atmosphere via the vents  148 . 
         [0064]    Generally, the heating/melting is controlled by a heating system  158  comprising at least one (preferably two) immersion heaters and at least one generator. The generator(s) supplies electricity for the electric motors that power the apparatus  100  and operate the blade  144  and the conveyor  142 . It is also intended to supply electricity to the two immersion heaters. 
         [0065]    The immersion heater is part of a closed-circuit system that supplies heated fluid to the melting pipes. The fluid may be a water/anti-freeze mixture so that the apparatus  100  can be started even if left out in freezing (below 32° F.) conditions. Because this system is a closed circuit, none of the fluid is released into the environment. Further, the immersion heater may help to melt snow/ice/etc. to steam. This steam is directed onto incoming snow, helping melt it and at the same time some of the steam is vaporized into the atmosphere via the vents  148 . In one particular embodiment the apparatus  100  further comprises at least one solar panel  150 . Often, on the day following a snow storm, the sun is shining and the solar panel  150  can augment the power of the electrical generator. In some embodiments, multiple solar panels may be utilized and may be capable of being maneuvered into a position to best utilize each of the panels. For example, in one embodiment of the apparatus  100 , there are two solar panels  150  that may be slid out horizontally from one another. Not only does this double the area of solar panels  150  available for collecting solar energy, but it also allows sunlight to directly heat the interior of the apparatus  100 . With appropriate cover, this can obtain extra heating for the apparatus  100  through the greenhouse effect. 
         [0066]    In another embodiment of the present invention the side panels or storage panels  154  on the apparatus  100  allow for the storage of equipment such as containers of gas for the electrical generator. Another use for the storage panels  154  is a place to locate batteries for storing electricity. These may be lithium-ion batteries like the Tesla Powerwall batteries, or more conventional lead acid batteries. Another potential use of the storage panels  154  may be to house forms that allow the melted snow/ice/etc. to be frozen into blocks shaped like large Lego® blocks or other conveniently shaped blocks. When the apparatus  100  is operating in sub-zero temperatures, simply pumping the melted snow into appropriately shaped forms will produce the ice bricks. These ice bricks can then be stacked out of the way. As ice is one tenth the volume of freshly fallen snow, this is another way in which the vehicle can solve the problem of getting the snow removed and prevent unwanted build up. 
         [0067]    When the apparatus is intended to be operated remotely, a unit housing sensing equipment  146  such as cameras, laser radar and GPS equipment, similar to that found on Google&#39;s autonomous vehicles may be employed to not only direct the pathway of the apparatus  100  but to help the apparatus  100  avoid obstacles as well. 
         [0068]    Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made only by way of illustration and that numerous changes in the details of construction and arrangement of parts may be resorted to without departing from the spirit and the scope of the invention.
