Food garbage disposer

Abstract

Disclosed herein is a food garbage disposer including: a reaction vessel which includes a hopper into which food garbage is introduced, a heating tank filed with heat-medium oil to heat the hopper, and at least one heater to heat the heat-medium oil in the hopper; an automatic filter which includes an automatic injection nozzle and filters vapor discharged from the reaction vessel; a condenser which condenses the vapor passed through the automatic filter and separate the vapor into condensed water and air; a condensed-water purifier which purifies the condensed water produced by the condenser and supplies the purified water to the automatic injection nozzle of the automatic filter; a deodorizer which purifies and deodorizes the air produced by the condenser; and an air circulation adjuster which mixes the air passed through the deodorizer with external air and reintroduces the mixed water into the reaction vessel. With this configuration, the food garbage disposer is improved in not only preventing an offensive odor from generating since the condensed water produced in the condenser is utilized for filtering the vapor discharged out of the reaction vessel, but also automating a full operation thereof since temperature of the reaction vessel is automatically controlled to facilitate drying and decomposition of the food garbage.

 a condenser which condenses the vapor passed through the automatic filter and separate separates the vapor into condensed water and air; 
 a condensed-water purifier which purifies the condensed water produced by the condenser and supplies the purified water to the automatic injection nozzle of the automatic filter; 
 a deodorizer which purifies and deodorizes the air produced by the condenser; and 
 an air circulation adjuster which mixes the air passed through the deodorizer with external air and reintroduces the mixed water air into the reaction vessel. 
 
     
     
       2. The food garbage disposer according to  claim 1 , further comprising a controller which controls the heater according to a temperature change inside the hopper so that temperature of the heat-medium oil is adjusted to facilitate drying and decomposition of the food garbage. 
     
     
       3. The food garbage disposer according to  claim 1 , wherein the reaction vessel comprises a hopper temperature sensor to sense temperature inside the hopper; and a heat-medium oil temperature sensor to sense temperature of the heat-medium oil. 
     
     
       4. The food garbage disposer according to  claim 1 , wherein the deodorizer comprises a heat supply tube and a catalyst tube,
 the heat supply tube being mounted while penetrating the heating tank. 
 
     
     
       5. The food garbage disposer according to  claim 1 , wherein the condenser comprises a plurality of cooling pipes and at least one cooling fan to cool the plurality of cooling pipes. 
     
     
       6. The food garbage disposer according to  claim 4 , wherein the cooling pipe comprises at least one lattice contact mesh placed therein, and a coil-shaped aluminum pin attached to an outer circumference thereof. 
     
     
       7. The food garbage disposer according to  claim 1 , further comprising a rotary stirring impeller placed inside the hopper of the reaction vessel and stirring the food garbage. 
     
     
       8. The food garbage disposer according to  claim 6 , wherein
 the stirring impeller comprises an impeller shaft having one end coupled to a lateral wall of the hopper, and 
 the one end of the impeller shaft is coupled to the lateral wall of the hopper by a plurality of gland packings and a packing cover allowing the gland packing to be adjusted with an adjusting bolt. 
 
     
     
       9. The food garbage disposer according to  claim 8 , wherein the one end of the impeller shaft is provided with an oil-seal to prevent a leakage that may leak from the hopper from being introduced into a bearing for allowing the impeller shaft to rotate, and a falling hole to make the leakage fall down to prevent the leakage from reaching the bearing. 
     
     
       10. The food garbage disposer according to  claim 1 , wherein the air circulation adjuster comprises:
 a rotary wing which is perpendicularly attached to assist air circulation; 
 a check valve which is placed above the rotary wing and prevents the vapor produced in the reaction vessel from flowing backward; 
 a rotation guide structure which reintroduces the air produced from the deodorizer into the reaction vessel; 
 an inhale/exhaust pipe which is coupled to a bottom of the air circulation adjuster and through which air is inhaled and exhausted; and 
 an air purifying filter which is detachably coupled to an end part of the inhale/exhaust pipe. 
 
     
     
       11. The food garbage disposer according to  claim 1 , wherein the automatic filter comprises:
 a filtering box through which the vapor discharged from the reaction vessel passes; 
 a filter which filters the vapor passed through the filtering box; and 
 a gear pump which is provided for injecting the condensed water through the automatic injection nozzle. 
 
     
     
       12. The food garbage disposer according to  claim 6 , wherein the condensed-water purifier comprises:
