DETAILED DESCRIPTION

(11) The snow melter machine and apparatus of the present disclosure generally consists of a body, preferably an insulated body, that houses a several components directed to transporting and melting snow and ice, followed by transporting the melted water to a place where it can be more easily stored in liquid water form. In more sophisticated models the body houses electrical components such as signaling relays, feedback mechanisms, thermometers, various pressure monitoring devices, volumetric measuring devices, and other components. The present disclosure discloses new and improved structural features for snow removal and ease of transport. Particularly the performance, durability, workability, and convenience of the present device is not present in other snow removal devices currently on the market as they cannot be used to relocate large amounts of snow and ice in a liquid form to a desired location. Also, due to the relatively compact and lightweight design, the snow melter machine of the present disclosure represents a significant advancement in ease of use over other, similar devices.

(12) Referring now to FIG. 1, a preferred embodiment of snow removal machine 10 of the present disclosure includes a body 11, snow input port 20 located at proximal end 18, reservoir area 30 located at distal end 19, axel 12 and wheels 13. Within body 11 resides snow compartment 15 which also functions as a heating element in certain preferred embodiments. The body 11 also may have handles 14 for better control of the device 10 and use in combination with wheels 13.

(13) Looking now with more specify to FIGS. 5, 6, 8, 9 snow input port or hopper 20 preferably comprises at least snow inlet 21 and an output (closes at 25) to main body 11 and compartment 15. In a preferred embodiment, inlet 21 is specifically adapted to complement the output of a conventional snowblower, easing the operation of the device, in such an embodiment the port 20 comprises a baffle 22 and an air flow exit slit 27, such devices causing snow to be deflected downward and into the remaining space in the snow input port 20 while quickly moving air flows through the exit slit 27 to allow for smooth flow from the snowblower. In other embodiments port 20 has a removable top 28 making it more compatible with traditional snow removal devices such as shovels. In a preferred embodiment, port 20 also comprises actuating flaps 23, 25 and ramp 24. Transition chamber flap 23 and hot chamber flap 25 can preferably be spring loaded or mechanically actuated. When mechanically actuated flaps 23, 25 may preferably be independently actuatable or may move simultaneously in response to a signal. In a preferred embodiment, the transition flap 23 remains open until a signal is given by the user or by an automatic signal based on outside measurements and the hot chamber flap 25 remains closed (as show in FIG. 9), preventing flow from port 20 into the main body 11. Upon signaling, the transition flap 23 closes and hot chamber flap 25 opens thereby preventing additional flow of snow and ice into the space 29 defined by flaps 23, 25 and ramp 24 while snow and ice in such space flows into the heated chamber 15. After space 29 is cleared, flap 25 closes, and flap 23 opens allowing additional flow of snow and ice into space 29. Preferably, in certain embodiments, monitor sensors connected to control circuitry, capable of detecting the snow charge inside of the snow port 20 are built into the port. These sensors and control circuits are preferably paired to the mechanically actuated flaps 23, 25.

(14) Looking now to FIGS. 2, 5, 7 reservoir area 30 is shown in greater detail. Reservoir area 30 preferably contains a pump 31, which is capable of pumping melted snow and ice out of body out through hose 35. In certain embodiments reservoir area 30 comprises two screens 32, 33 which define a secondary buffering area 34. Screen 32 is preferably a coarse screen for filtering out large rocks, sticks, unmelted ice, and other solids and screen 33 is preferably a fine screen for filtering sand and other smaller solids. Screens 32, 33 are preferably removable for simple cleaning of the device after use and for preventing corrosion of the screens. In certain preferred embodiments the meltwater reservoir 30 contains a volumetric measuring device that measures the levels of meltwater within the reservoir. In such embodiments water levels may selectively signal to control circuits located elsewhere in the snow melting machine 10, specifically, the transition 23 and hot chamber 25 flaps may preferably move in response to water levels in the reservoir are below a certain threshold level. Volumetric monitors may also selectively control operation of the pump 31, which may be selectively shut off when water levels are below a threshold level to conserve energy and heat.

(15) Looking now to the specific operation of the snow melting machine 10, the machine may be adapted to operation with a 240 volt domestic electronic circuit, or adapted to use with a gasoline engine. The machine's general structure relates to the body 11, and insulated chamber 15, wherein snow charge input through snow port 20 is melted using a infrared radiant heater. Insulated chamber 15 is preferably surrounded by high-performance furnace insulation with very low thermal conductivity. The thickness of such insulation is selected to minimize power loss to the atmosphere. Preferably the heater or heating element is a 13.5 kW infrared heater and is powered by a 240, 50 am electrical circuit. In certain embodiments, portable means of providing electricity to the snow melting machine are also contemplated, such as portable electronic generators.

(16) The machine's snow port 20 is at the proximal end of a tilted, internal snow ramp formed within body 11 and insulated chamber 15 which allows energy to be saved by virtue of the operation of gravity. Within the snow port 20 and chamber 15, monitor sensors detect snow charge and servo control circuitry closes flap 23 and opens flap 25 allowing snow to pass into chamber 15. Flap 25 then is closed and the radiant heater or heating element is energized and remains energized until monitor sensors indicate no solid snow remains in chamber 15. Water then drains from chamber 15 into reservoir 30 through gratings 32, 33 and to pump 31. Pump 31 is preferably an electric pump operated by a level switch in the reservoir and transfers water to a domestic drain or other disposal area preferably through a hose 35.

(17) The foregoing is illustrative of the present invention and is not to be construed as limiting thereof. Although exemplary embodiments of this invention have been described, those skilled in the art will readily appreciate that many modifications are possible in the exemplary embodiments without materially departing from the novel teachings and advantages of this invention. Accordingly, all such modifications are intended to be included within the scope of this invention as defined in the claims. The invention is defined by the following claims, with equivalents of the claims to be included therein.
