The laundry treatment apparatus includes a receiving unit for providing a laundry receiving space, an introduction port for allowing the receiving unit to communicate with the outside of the laundry treatment apparatus, a door for opening and closing the introduction port, an actuation unit provided at the door such that the actuation unit reciprocates between a first position and a second position, and a fixing unit for fixing the door to the introduction port using an attractive force when the actuation unit is positioned at the first position and for separating the door from the introduction port when the actuation unit is positioned at the second position. ## Claims ### Claim 1 A laundry treatment apparatus comprising: a receiving unit configured to receive laundry; an introduction port configured to allow the receiving unit to communicate with an outside of the laundry treatment apparatus; a door configured to open and close the introduction port; an actuation unit comprising: an actuation body provided at the door and configured to move between a first position and a second position; and a magnetic body fixed to the actuation body; and a fixing unit that is configured to fix the door to the introduction port by an attractive force based on the actuation unit being positioned at the first position, and that is configured to separate the door from the introduction port based on the actuation unit being positioned at the second position, the fixing unit comprising a magnet fixed to the receiving unit and configured to apply an attractive force to the magnetic body based on the actuation body being moved to the first position, wherein the actuation unit further comprises a non-magnetic body fixed to the actuation body, and the non-magnetic body is configured to face the magnet based on the actuation body being moved to the second position. ### Claim 2 (depends on 1) The laundry treatment apparatus according to claim 1, further comprising: an actuation body receiving unit that is provided in the door and that is configured to receive the actuation body; and an actuation body support unit provided in the actuation body receiving unit and that is configured to push the actuation body to the first position while elastically supporting the actuation body. ### Claim 3 (depends on 1) The laundry treatment apparatus according to claim 1, further comprising: a cabinet configured to provide a space to receive the receiving unit; and a through hole provided in the cabinet and configured to communicate with the introduction port. ### Claim 4 (depends on 1) The laundry treatment apparatus according to claim 1, further comprising: a cabinet; a drawer provided in the cabinet and configured to provide a space to receive the receiving unit; and a through hole provided in the drawer, the through hole being located above the door for allowing the door to be hingedly rotated toward an outside of the drawer. ### Claim 5 (depends on 4) The laundry treatment apparatus according to claim 4, wherein: the fixing unit is fixed to the receiving unit, and the actuation unit is configured to move in a width direction of the door or in a height direction of the door. ### Claim 6 (depends on 5) The laundry treatment apparatus according to claim 5, wherein the actuation unit is configured to move in a width direction of the door. ### Claim 7 (depends on 5) The laundry treatment apparatus according to claim 5, wherein the actuation unit is configured to move in a height direction of the door. ### Claim 8 A laundry treatment apparatus comprising: a receiving unit configured to receive laundry; an introduction port configured to allow the receiving unit to communicate with an outside of the laundry treatment apparatus; a door configured to open and close the introduction port; an actuation unit comprising: an actuation body provided at the door and configured to move between a first position and a second position; and a magnetic body fixed to the actuation body; and a fixing unit that is configured to fix the door to the introduction port by an attractive force based on the actuation unit being positioned at the first position, and that is configured to separate the door from the introduction port based on the actuation unit being positioned at the second position, the fixing unit comprising a magnet fixed to the receiving unit and configured to apply an attractive force to the magnetic body based on the actuation body being moved to the first position, wherein the magnetic body comprises a first magnetic body and a second magnetic body fixed to the actuation body such that the first magnetic body and the second magnetic body are spaced apart from each other by a predetermined distance, and the magnet comprises a first magnet configured to face the first magnetic body based on the actuation body being positioned at the first position, and a second magnet configured to face the second magnetic body based on the actuation body being positioned at the first position. ### Claim 9 (depends on 8) The laundry treatment apparatus according to claim 8, wherein the actuation unit further comprises a non-magnetic body provided between the first magnetic body and the second magnetic body such that the non-magnetic body is configured to face the first magnet or the second magnet based on the actuation body being moved to the second position. ### Claim 10 A laundry treatment apparatus comprising: a receiving unit configured to receive laundry; an introduction port configured to allow the receiving unit to communicate with an outside of the laundry treatment apparatus; a door configured to open and close the introduction port; an actuation unit provided at the door and configured to move between a first position and a second position; and a fixing unit that is configured to fix the door to the introduction port by an attractive force based on the actuation unit being positioned at the first position, and that is configured to separate the door from the introduction port based on the actuation unit being positioned at the second position, wherein: the fixing unit comprises a magnetic body fixed to the receiving unit, and the actuation unit comprises: an actuation body provided at the door and configured to move between the first position and the second position; and a magnet fixed to the actuation body and configured to apply an attractive force to the magnetic body based on the actuation body being moved to the first position, and the fixing unit further comprises a non-magnetic body fixed to the receiving unit such that the non-magnetic body is configured to face the magnet based on the actuation body being moved to the second position.
