  • Patent Document 1 Korean Laid-Open Patent Publication No. KR 10-2011-0028899A (published on March 22, 2011; hereinafter, referred to as Patent Document 1).
  • a support unit is installed on a rear surface of a door. When the door opens and closes a laundry inlet port, the support unit maintains a spaced distance between the door and a main body.
  • the support unit is brought into contact with a flat surface of a recess part recessed into a front surface of the main body, such that the spaced distance between the door and the main body is maintained. Accordingly, a ventilation gap is formed between the door and the main body.
  • the support unit serves to ventilate an inner space of the main body and outside through the ventilation gap (see FIG. 4A of Patent Document 1).
  • the support unit contacts the flat surface of the recess part of the main body when the door is opened and closed, thereby alleviating an impact transferred to the main body through the door.
  • Patent Document 1 has the following problems.
  • the support unit since the support unit has a structure protruding separately from a rear surface of a door frame, appearance of the door is spoiled.
  • the door frame protrudes outward from the recess part of the main body and is spaced apart from the recess part with the ventilation gap therebetween, the protruding structure of the door is exposed to outside through the ventilation gap even when the door is closed, thereby degrading appearance quality of the door.
  • the support unit protrudes so as to contact the flat surface inside the recess part. This causes an increase in size of the support unit and adversely affects appearance quality.
  • the support unit includes a support body and a magnet provided inside the support body, so that the support body is coupled to the main body by magnetic force. As a result, the user should pull the door harder to open the door because of attraction force of the magnet.

  • a rear surface of the door is brought into contact with the portion where the recess part starts to be recessed, by virtue of the contact portion.
  • the contact portion covers inside of the recess part. Therefore, the door window protruding from the rear surface of the door to the inner space of the main body can be covered, thereby improving appearance of the door.
  • the contact portion of the door comes in contact with the recessed portion where the recess part starts to be recessed without protruding from the rear surface of the door and also contacting a flat surface of the recess part, thereby preventing an increase in an unnecessary material cost due to an increase in size of the contact portion.
  • the contact portion has a cross section in an arcuate shape and is curved toward the front panel or recess part, so as to come in point contact or line contact with an outer circumference of the recess part. According to this, a contact area of the contact portion can be minimized when the door is closed, thereby distributing an impact, which is applied to the main body when the contact portion of the door comes in contact with the recess part of the main body, along the circumferential direction of the recess part, which may result in minimizing an impact applied to the main body.
  • the hinge unit and the locking unit are coupled to the main body and the contact portion comes in contact with an upper end of the recess part when the door is closed. Accordingly, at least three support points, like an equilateral triangle, a rectangle, and a polygon, can be formed by the contact between the door and the main body, thereby reducing vibration or shaking of the door and absorbing an impact applied to the door.
  • an arcuate curved surface of the contact portion and an arcuate curved surface of an outer circumference of the recess portion can come in point contact or line contact with each other between the door and the main body, thereby minimizing friction between the door and the main body.
  • the contact portion and the recess part are externally brought into contact with each other. Accordingly, a contact point between the contact portion and the recess part can move on the arcuate curved surface of the contact portion, thereby preventing separation between the contact portion of the door frame and the recess part of the main body so as to realize stable contact between them.
