Through the structure as such, the accuracy in detecting dryness of laundry is enhanced, and an optimal controlling of the clothing dryer may be possible. ## Claims ### Claim 1 A clothing dryer, comprising: a cabinet; a drying tub positioned at an inner side of the cabinet and configured to accommodate laundry; a plurality of moisture detecting sensor units provided at an inside the drying tub to detect moisture of laundry; and a sensor partition wall provided in between the plurality of moisture detecting sensor units to prevent a foreign substance from being stuck in between the plurality of moisture detecting sensor units. ### Claim 2 (depends on 1) The clothing dryer of claim 1, wherein: the plurality of moisture detecting sensor units each comprises a moisture detection sensing part exposed to an inside of the drying tub; and a fixing-bent part bent from one end portion of the moisture detection sensing part to fix the moisture detection sensing part. ### Claim 3 (depends on 2) The clothing dryer of claim 2, further comprising: a filter member provided in between the drying tub and a duct communicating with the drying tub and through which air passed through an inside the drying tub is discharged, to filter a foreign substance, wherein the moisture detecting sensor unit is provided on the filter member. ### Claim 4 (depends on 3) The clothing dryer of claim 3, wherein: the filter member comprises a filter member body forming an exterior appearance of the filter member; an air discharging port provided at the filter member body in the shape of a hollow hole such that the air passed through an inside the drying tub is discharged; and a sensor mounting part provided on the filter member body and at which the moisture detecting sensor unit is disposed. ### Claim 5 (depends on 4) The clothing dryer of claim 4, wherein: the sensor mounting part comprises a first mounting part at which the moisture detection sensing part is mounted; and a second mounting part provided at one end portion of the first mounting part and at which the fixing-bent part is insertedly mounted. ### Claim 6 (depends on 5) The clothing dryer of claim 5, wherein: the second mounting part is open toward a lower side thereof such that accumulated moisture is discharged therethrough. ### Claim 7 (depends on 2) The clothing dryer of claim 2, wherein: the sensor partition wall comprises at least one moisture detection sensing part partition wall configured to divide the plurality of moisture detection sensing parts such that no foreign substance is stuck in between the plurality of moisture detection sensing parts. ### Claim 8 (depends on 2) The clothing dryer of claim 2, wherein: the sensor partition wall comprises at least one fixing part partition wall configured to divide the plurality of fixing-bent parts such that no foreign substance is stuck in between the plurality of fixing-bent parts. ### Claim 9 (depends on 1) The clothing dryer of claim 1, wherein: the plurality of moisture detecting sensor units comprise a pair of the moisture detecting sensor units provided in parallel to each other. ### Claim 10 (depends on 2) The clothing dryer of claim 2, wherein: the plurality of fixing-bent parts comprise a hook inclination surface inclined in a direction opposite to an insertion direction in which the fixing bent part is inserted into the second mounting part to prevent the plurality of fixing-bent parts from being separated at the time of when the plurality of fixing-bent parts are being inserted into the filter member. ### Claim 11 (depends on 2) The clothing dryer of claim 2, wherein: the plurality of moisture detecting sensor units further comprise a terminal connecting part bent from the other end portions of the moisture detection sensing parts to detect dryness of laundry and deliver the detected dryness of laundry to a control unit. ### Claim 12 A clothing dryer, comprising: a cabinet; a drying tub disposed at an inner side of the cabinet to accommodate laundry; a plurality of moisture detecting sensor units including a plurality of moisture detection sensing parts exposed toward an inside of the drying tub, and a plurality of fixing-bent parts extendedly formed from the plurality of moisture detecting sensor units such that the plurality of moisture detecting sensor units are fixed, to detect dryness of laundry accommodated at an inside the drying tub; and at least one sensor partition wall configured to divide the plurality of moisture detecting sensor units from each other, wherein the at least one sensor partition wall comprises at least one moisture detection sensing part partition wall dividing the plurality of moisture detection sensing parts from each other; and at least one fixing-hook part partition wall dividing the plurality of fixing-bent parts from each other. ### Claim 13 (depends on 12) The clothing dryer of claim 12, further comprising: a first space at which the plurality of fixing-bent parts are mounted, and provided at one side thereof with a discharging opening to prevent moisture in the air inside the drying tub from being accumulated, wherein the at least one fixing-hook part partition wall is provided as to divide the first space. ### Claim 14 (depends on 13) The clothing dryer of claim 13, wherein: the first space is divided by the at least one fixing-hook part partition wall. ### Claim 15 (depends on 14) The clothing dryer of claim 14, wherein: the plurality of fixing-bent parts are disposed at the first spaces that are divided by the at least one fixing-hook part partition wall. ### Claim 16 (depends on 12) The clothing dryer of claim 12, further comprising: a filter member provided in between the drying tub and a duct communicating with the drying tub and through which air passed through an inside the drying tub is discharged, to filter a foreign substance, wherein the plurality of moisture detecting sensor units are disposed on the filter member. ### Claim 17 (depends on 12) The clothing dryer of claim 12, wherein: the plurality of moisture detection sensing parts are formed in a circumferential direction corresponding to a rotational direction of the drying tub. ### Claim 18 (depends on 12) The clothing dryer of claim 12, wherein: the plurality of fixing-hook units are disposed as to be spaced apart from each other with respect to left and right directions.
