Purifier and garbage disposer

Abstract

A purifier to purify exhaust gas includes a case, a plurality of metal sheets disposed in the case, a catalyst held to each of the metal sheets, partition plates disposed between the respective metal sheets, a metallic pipe disposed piercing through the metal sheets, and a catalyst heater disposed in the metallic pipe. The plurality of metal sheets are arranged at predetermined intervals, and each of the metal sheets has at least one through-hole. The partition plates serve to partition the spaces between the respective metal sheets. The exhaust gas is circulated through the spaces between the respective metal sheets and then passes through the through-holes and is exhausted from the outlet of the case. In this way, it is possible to increase the number of metal sheets without increase of the pressure loss and to enlarge the outer diameter of same.

1 . A garbage disposer capable of purifying exhaust gas, comprising: 
 a storage section to store garbage;    a main heater to heat said storage section; and    a purifier connected to said storage section, said purifier for purifying exhaust gas, said purifier including:    (a) a case having an inlet and an outlet;    (b) a plurality of thin plates disposed in said case, said thin plates being arranged at predetermined intervals, and each of said thin plates having at least one through-hole;    (c) a catalyst held to each of said thin plates;    said catalyst having a function of purifying the exhaust gas;    (d) partition plates disposed between the respective thin plates,    said partition plates partitioning the spaces between the respective thin plates; and    (e) a catalyst heater to heat each of said thin plates,    wherein the exhaust gas enters into said case from said inlet, and passes through the spaces formed between the respective thin plates, and each of said through-holes, and is exhausted from said outlet.    
     
     
         2 . The garbage disposer of  claim 1 , 
 wherein said purifier includes a temperature detector, and    when said temperature detector detects abnormal combustion in said purifier, the operation of at least one of said main heater and said catalyst heater is discontinued.    
     
     
         3 . The garbage disposer of  claim 1 , 
 wherein said purifier further comprises a pipe,    said catalyst heater is installed in said pipe;    said plurality of thin plates are fixed around said pipe;    said through-hole and said partition plate are disposed in positions such that the exhaust gas is circulated through the spaces;    said thin plates are made of metal;    said pipe is also made of metal; and    the catalyst has a function of deodorizing the exhaust gas.    
     
     
         4 . The garbage disposer of  claim 1 , 
 wherein said partition plate is bonded to each of said thin plates.    
     
     
         5 . The garbage disposer of  claim 1 , 
 wherein at least one of said partition plate and said through-hole is formed by cutting and raising said thin plate.    
     
     
         6 . The garbage disposer of  claim 1 , further comprising: 
 wire netting disposed along the periphery of said thin plates; and    a heat insulating material disposed around said wire netting,    wherein each of said thin plates is substantially circular in shape;    said case is substantially cylindrical in shape; and    said wire netting and said heat insulating material are disposed in said case.    
     
     
         7 . The garbage disposer of  claim 1 , 
 wherein said partition plate includes a plurality of partition plates;    said through-hole includes a plurality of through-holes;    a plurality of spaces separated by said plurality of partition plates are formed between the respective thin plates;    said spaces are respectively connected to said through-holes;    the exhaust gas enters into said case from said inlet, and is separately circulated passing through respective ones of said spaces and said through-holes and is exhausted from said outlet.    
     
     
         8 . The garbage disposer of  claim 1 , 
 wherein said purifier further comprises:    an inlet pipe disposed at said inlet;    an outlet pipe disposed at said outlet;    a low-temperature catalyst that functions at a lower temperature as compared with the catalyst mentioned earlier; and    said low-temperature catalyst is disposed in at least one of said inlet pipe and said outlet pipe.
