Grease filter

Abstract

A grease filter capable of reducing a pressure loss generated while air passes through the grease filter, and cooking apparatus are provided. The grease filter includes an inflow portion configured for oil particles to be introduced therethrough, and a channel provided to discharge air current and oil particles, which are introduced through the inflow portion, to an outside, wherein the channel includes an upper channel disposed in parallel while spaced apart in a predetermined distance to form the inflow portion, and a lower channel comprising a direction changing portion provided to change a direction of the air current and the oil particles introduced through the inflow portion, and a guide portion having a predetermined angle to guide the oil particles and the air current having been changed in direction by the direction changing portion.

What is claimed is: 
     
         1 . A grease filter, comprising:
 an inflow portion configured for oil particles to be introduced therethrough; and   a channel provided to discharge air and oil particles, which are introduced through the inflow portion, to an outside, and   wherein the channel comprises:
 an upper channel disposed in parallel, while spaced apart a predetermined distance, to form the inflow portion; and 
 a lower channel comprising a direction changing portion provided to change a direction of the air current and the oil particles introduced through the inflow portion, and a guide portion having a predetermined angle to guide the oil particles and the air current, of which the direction is changed by the direction changing portion. 
   
     
     
         2 . The grease filter of  claim 1 , wherein the guide portion is formed in an obtuse angle with respect to the direction changing portion. 
     
     
         3 . The grease filter of  claim 1 , wherein the upper channel comprises:
 an inflow guide formed in a predetermined angle to form the inflow portion, and a multiple-surface portion extending from the inflow guide to maximize a contact surface of the oil particles.   
     
     
         4 . The grease filter of  claim 3 , wherein the multiple-surface portion is provided in plural. 
     
     
         5 . The grease filter of  claim 3 , wherein the multiple-surface portion comprises an inner angle formed by having each surface of the multiple-surface portion meet one another, and
 the inner angle is formed to be equal to or greater than 90 degrees   
     
     
         6 . The grease filter of  claim 3 , wherein the multiple-surface portion is formed in a way to surround an outer side of the guide portion of the lower channel. 
     
     
         7 . The grease filter of  claim 3 , wherein the channel comprises a discharging portion configured to discharge the oil particles and the air current to an outside, and
 the discharging portion is formed between the guide portion of the lower channel and at least one surface of the multiple-surface portion of the upper channel.   
     
     
         8 . The grease filter of  claim 7 , wherein the guide portion and the at least one surface of the multiple-surface portion forming the discharging portion are disposed in parallel to each other. 
     
     
         9 . The grease filter of  claim 7 , wherein a width of the guide portion and a width of the at least one surface of the multiple-surface portion forming the discharging portion are gradually narrowed toward the outside. 
     
     
         10 . The grease filter of  claim 3 , wherein an end portion of the multiple-surface portion is diverged to be disposed opposite each other. 
     
     
         11 . A cooking apparatus, comprising:
 a heating apparatus;   a body provided with the heating apparatus at an upper side thereof;   a suction portion provided to intake oil particles and air, which are generated through the cooking portion, from a side of the body; and   a grease filter configured to capture oil particles that are taken in through the suction portion,   wherein the grease filter comprises:
 an inflow portion configured for oil particles and air current to be introduced therethrough, and 
 a panel provided for the oil particles and the air current that are introduced through the inflow portion to be discharged to an outside, and 
   wherein the panel, comprises:
 an upper channel provided in parallel while being spaced apart in a predetermined distance to form the inflow portion, and 
 a lower channel comprising a direction changing portion provided to change a direction of the oil particles and the air current that are introduced through the inflow portion, and a guide portion having a predetermined angle to guide the oil particles and the air current, of which the direction is changed by the direction changing portion. 
   
     
     
         12 . The cooking apparatus of  claim 11 , wherein the suction portion is configured to extend formed from the one side of the body upward, and comprises
 a plurality of suction holes formed to intake the oil particles and the air current, which are generated from the heating apparatus, sideways.   
     
     
         13 . The cooking apparatus of  claim 11 , wherein the guide portion is formed in an obtuse angle with respect to the direction changing portion. 
     
     
         14 . The cooking apparatus of  claim 11 , wherein the multiple-surface portion is provided in plural, and comprises an inner angles formed as each surface of the multiple-surface portion meets one another, and
 the inner angle is formed to be equal to or greater than  90  degrees.   
     
     
         15 . The cooking apparatus of  claim 11 , wherein the channel comprises a discharging portion configured to discharge the oil particles and the air current to an outside, and
 the discharging portion is formed between the guide portion and at least one surface of the multiple-surface portion.   
     
     
         16 . A filter to discharge a gas and particles that are introduced, comprising:
 a first channel for inflow of the gas and the particles; and   a second channel comprising:
 a direction changing portion to change a direction of the gas and the particles introduced through the first channel, and 
 an angled guide portion to guide the particles and the gas.
