A door assembly 100 for an air conditioner indoor unit according to an embodiment of the present disclosure is described below with reference to
As shown in
That is, the door mounting plate 1 has a receiving groove 121 in which the drive assembly 4 can be mounted, and the drive assembly 4 can cooperate with the door 2 to drive the door 2, so that the door 2 moves towards the door mounting plate 1, or the door 2 moves in a direction away from the door mounting plate 1.
The side of the door 2 facing the door mounting plate 1 is provided with the guiding part 3, and the side of the door mounting plate 1 facing the door 2 is provided with the guiding groove 122, and the guiding part 3 can cooperate with the guiding groove 122, so that the guiding part 3 can slide along the guiding groove 122 during the movement of the door 2, and the stability of the door 2 is good.
For convenience of explanation, as shown in
Thus, for the door assembly 100 according to the first embodiment of the present disclosure, the guiding part 3 can slide along the guiding groove 122 when the drive assembly 4 drives the door 2 to move forward or backward, and the door 2 can also slide along with the guiding part 3, so that the door 2 has a better stability when moving. In addition, while the guiding stricture 3 is sliding along the guiding groove 122, the guiding groove 122 can also limit the guiding part 3, thereby controlling the movement track of the door, making the movement trajectory of the door more precise.
In some embodiments of the present disclosure, as shown in
In some embodiments of the present disclosure, the receiving groove 121 is formed at a side of the mounting part 12 far from the door 2, the drive assembly 4 is disposed in the receiving groove 121, and at least one part of the drive assembly 4 passes through the bottom wall 1212 of the receiving groove 121 and then is connected to the door 2. That is to say, the drive assembly 4 may be partially connected to the door 2 after passing through the bottom wall 1212 of the receiving groove 121, or may be connected to the door 2 after thoroughly passing through the bottom wall 1212 of the receiving groove 121.
