Control unit of laundry processing apparatus
A control unit of a laundry treatment apparatus is provided in which shaking of a knob may be reduced or prevented and a tactile manipulation response of the knob may be improved. The control unit may include a board provided in a control panel of the laundry treatment apparatus, an encoder mounted in the board and having a projected rotation shaft, a supporter mounted in the board or the control panel and having a hollow unit disposed outside the rotation shaft, a knob having a connecting shaft coupled to the rotation shaft, and a bushing mounted in the hollow unit and rotatably supporting at least one of the connecting shaft or the rotation shaft.
1. A control unit of a laundry treatment apparatus, comprising:
a board provided in a control panel of the laundry treatment apparatus;
an encoder mounted in the board and having a projected rotation shaft;
a supporter mounted in the board or the control panel and having a hollow unit disposed outside the rotation shaft;
a knob having a connecting shaft coupled to the rotation shaft; and
a bushing mounted in the hollow unit and rotatably supporting at least one of the connecting shaft or the rotation shaft, wherein the bushing comprises:
a mounting unit mounted in the hollow unit; and
a contact unit extending from the mounting unit and rotatably comming in contact with the connecting shaft or the rotation shaft, wherein the mounting unit comprises:
an outer circumference unit disposed on an outer circumference of the hollow unit; and
a connection unit connecting the outer circumference unit and the contact unit.
2. The control unit of the laundry treatment apparatus as claimed in claim 1 , wherein the bushing includes a plastic material or a metal material having a lubricative property.
3. A control unit of a laundry treatment apparatus, comprising:
a board provided at a control panel of the laundry treatment apparatus;
an encoder coupled the board and having a rotation shaft projecting therefrom;
a supporter coupled to the board or the control panel and having a hollow unit positioned outside the rotation shaft;
a knob having a connecting shaft coupled to the rotation shaft; and
a bushing mounted in the hollow unit and rotatably supporting at least one of the connecting shaft or the rotation shaft, wherein the bushing comprises:
a mounting unit mounted in the hollow unit; and
a contact unit extending from the mounting unit and rotatably contacting the connecting shaft or the rotation shaft, wherein the mounting unit comprises:
an outer circumference unit disposed on an outer circumference of the hollow unit;
an inner circumference unit disposed on an inner circumference of the hollow unit; and
a connection unit connecting the outer circumference unit the inner circumference unit, and the contact unit.
4. The control unit of the laundry treatment apparatus as claimed in claim 1 , wherein the mounting unit has a plurality of incision units formed therein, arranged in a circumferential direction, the plurality of incision units being spaced apart from each other.
5. The control unit of the laundry treatment apparatus as claimed in claim 1 , wherein the contact unit resiliently supports the connecting shaft or the rotation shaft.
6. A control unit of a laundry treatment apparatus, comprising:
a board provided at a control panel of the laundry treatment apparatus;
an encoder coupled the board and having a rotation shaft projecting therefrom;
a supporter coupled to the board or the control panel and having a hollow unit positioned outside the rotation shaft;
a knob having a connecting shaft coupled to the rotation shaft; and
a bushing mounted in the hollow unit and rotatably supporting at least one of the connecting shaft or the rotation shaft, wherein the bushing comprises:
a mounting unit mounted in the hollow unit; and
a contact unit extending from the mounting unit and rotatablv contacting the connecting shaft or the rotation shaft, wherein the contact unit is inclined from the mounting unit to the connecting shaft or the rotation shaft.
7. A control unit of a laundry treatment apparatus, comprising:
a board provided at a control panel of the laundry treatment apparatus;
an encoder coupled the board and having a rotation shaft projecting therefrom;
a supporter coupled to the board or the control panel and having a hollow unit positioned outside the rotation shaft;
a knob having a connecting shaft coupled to the rotation shaft; and
a bushing mounted in the hollow unit and rotatably supporting at least one of the connecting shaft or the rotation shaft wherein the bushing comprises:
a mounting unit mounted in the hollow unit; and
a contact unit extending from the mounting unit and rotatably contacting the connecting shaft or the rotation shaft, wherein the contact unit includes a rib projected toward the connecting shaft or the rotation shaft along an inner circumference of the mounting unit.
8. The control unit of the laundry treatment apparatus as claimed in claim 7 , wherein a slot is formed at the end of the contact unit.
