The ice maker includes a case for protecting a cooling space to which cold air is supplied, an ice making assembly for making ice by using the cold air in the cooling space, an ice bucket for containing the ice made by the ice making assembly in the cooling space, a discharge assembly having an insulation space which is provided as a path through which the ice contained in the ice bucket is discharged to the outside of the case, and a deodorizing filter placed on a cold air channel that allows the cold air to go by the ice bucket after the cold air coming from the ice making assembly passes through the insulation space. ## Claims ### Claim 1 An ice maker for a refrigerator, comprising: a case for protecting a cooling space to which cold air is supplied; an ice making assembly for making ice by using the cold air in the cooling space; an ice bucket located in the cooling space configured for storing the ice made by the ice making assembly; a discharge assembly located outside the cooling space and comprising an insulation space, wherein the discharge assembly is configured to provide a path through which the ice stored in the ice bucket is discharged to the outside of the case; and a deodorizing filter placed in a path of a cold air channel that is configured to allow the cold air to circulate from the insulation space to the ice bucket after the cold air circulates from the ice making assembly to the insulation space via the cold air channel, wherein the discharge assembly comprises an insulation case having at least one insulation wall which is configured to form the insulation space, wherein the insulation case is configured to discharge the cold air circulating through the insulation space to the outside of the case through a discharge port formed at one side of the insulation wall, wherein the ice maker further comprises a partition installed between the ice making assembly and the discharge assembly, wherein the cooling space is spatially separated from the insulation space by the partition, and wherein the deodorizing filter is disposed in the insulation space, and wherein the partition comprises a ventilator configured to provide the cold air channel formed between the cooling space and the insulation space. ### Claim 2 (depends on 1) The ice maker of claim 1, wherein the discharge assembly comprises a heater for increasing a temperature of the cold air before discharging the cold air to the outside of the case through the discharge port. ### Claim 3 (depends on 1) The ice maker of claim 1, wherein the deodorizing filter is accommodated in a filter case that is attached to the insulation case and located in the insulation space. ### Claim 4 A method for deodorizing an odor of an ice maker used in a refrigerator, the method comprising: making ice by an ice making assembly using cold air, wherein the ice making assembly is located in a cooling space protected by a case; storing the ice made by the ice making assembly in the cooling space, wherein the ice is stored in an ice bucket; deodorizing the cold air circulating from the ice making assembly to an insulation space formed by a discharge assembly via a cold air channel by using a deodorizing filter placed in a path of the cold air channel; and allowing the cold air deodorized by the deodorizing filter to circulate from the insulation space to the ice bucket via the cold air channel, wherein the discharge assembly is located outside the cooling space and comprises an insulation case having at least one insulation wall which is configured to form the insulation space, wherein the insulation case is configured to discharge the cold air circulating through the insulation space to the outside of the case through a discharge port formed at one side of the insulation wall, wherein the ice maker further comprises a partition installed between the ice making assembly and the discharge assembly, wherein the partition spatially separates the cooling space from the insulation space, wherein the deodorizing filter is disposed in the insulation space, and wherein the partition comprises a ventilator configured to provide the cold air channel between the cooling space and the insulation space. ### Claim 5 (depends on 4) The method of claim 4, further comprising: increasing a temperature of the cold air before discharging the cold air to the outside through the discharge port. ### Claim 6 (depends on 4) The method of claim 4, further comprising: dispensing the ice to the outside of the case through the insulation space of the discharge assembly. ### Claim 7 A refrigerator, comprising: a freezer compartment located within a main body of the refrigerator; a refrigeration compartment located within the main body of the refrigerator; a case located within the refrigeration compartment, wherein the case is configured for protecting a cooling space to which cold air is supplied; an ice making assembly for making ice by using the cold air in the cooling space; a bucket located in the cooling space for storing the ice made by the ice making assembly; a discharge assembly located outside the cooling space and comprising an insulation space, wherein the discharge assembly is configured to provide a path through which the ice stored in the ice bucket is discharged to the outside of the case; and a deodorizing filter placed in a path of a cold air channel that is configured to allow the cold air to circulate from the insulation space to the ice bucket after the cold air circulates from the ice making assembly to the insulation space, wherein the discharge assembly comprises an insulation case having at least one insulation wall which is configured to form the insulation space, wherein the insulation case is configured to discharge the cold air circulating through the insulation space to the outside of the case through a discharge port formed at one side of the insulation wall, wherein the refrigerator further comprises a partition installed between the ice making assembly and the discharge assembly, wherein the partition makes the cooling space spatially separated from the insulation space, wherein the deodorizing filter is disposed in the insulation space, and wherein the partition comprises a ventilator configured to provide the cold air channel between the cooling space and the insulation space. ### Claim 8 (depends on 7) The refrigerator of claim 7, wherein the discharge assembly comprises a heater for increasing a temperature of the cold air before discharging the cold air to the outside of the case through the discharge port. ### Claim 9 (depends on 7) The refrigerator of claim 7, wherein the deodorizing filter is accommodated in a filter case that is attached to the insulation case and located in the insulation space. ### Claim 10 (depends on 7) The refrigerator of claim 7, further comprising: a dispenser integrated within a refrigeration compartment door, wherein the refrigerator compartment door is configured to isolate the refrigeration compartment from a surrounding environment and to provide access to the refrigeration chamber, and wherein the dispenser is aligned with the discharge assembly for receiving ice and discharging ice to the outside of the case. ### Claim 11 (depends on 7) The refrigerator of claim 7, wherein the freezer compartment is below the refrigeration compartment. ### Claim 12 (depends on 1) The ice maker of claim 1, wherein the cooling space is outside the insulation space.
