A door assembly 100 for an air conditioner indoor unit according to an embodiment of the present disclosure is described below with reference to FIGS. 1-9.


As shown in FIGS. 3-5, the door assembly 100 for an air conditioner indoor unit according to an embodiment of the present disclosure includes a door mounting plate 1, a door 2, a guiding part 3 and a drive assembly 4. The door mounting plate 1 is provided with a receiving groove 121, and the door mounting plate 1 is further provided with a guiding groove 122, the door 2 is movable in a direction approaching and away from the door mounting plate 1, the guiding part 3 is connected to the door 2 and is located on the side of the door 2 facing the door mounting plate 1, and the guiding part 3 is movably disposed in the guiding groove 122, and the drive assembly 4 is used to drive the door 2 to move and disposed in the receiving groove 121.


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 FIGS. 5 and 6, the direction of the door 2 facing the door mounting plate 1 is backward, and the direction of the door mounting plate 1 facing the door 2 is forward, so the drive assembly 4 can drive the door 2 to move forward or backward.


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 FIGS. 3 and 4, the door mounting plate 1 includes: a frame 11 and a mounting part 12, the mounting part 12 is disposed at the frame 11 and located at the lateral middle position of the frame 11, where the lateral direction refers to the left-right direction as shown in FIG. 1, therefore, the mounting part 12 is provided in the middle of the frame 11 in the left-right direction. The receiving groove 121 and the guiding groove 122 are formed at the mounting part 12, which can reduce the number of components in the door assembly 100 for the air conditioner indoor unit, and is convenient for assembly. Meanwhile, as shown in FIG. 5, the receiving groove 121 and the guiding groove 122 can be arranged in a nested manner, which can save the internal space of the door assembly 100 for the air conditioner indoor unit, and is advantageous for the layout thereof.


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.


Optionally, as shown in FIG. 3, the bottom wall 1212 of the receiving groove 121 is provided with a protruding slot 1211. The drive assembly 4 includes a motor, a gear and a rack 41. The rack 41 can pass through the protruding slot 1211 and connect with the door 2, and thereby drive the door 2 to move up and down in the front-rear direction. At this time, the driving assembly 4 is restricted between the mounting part 12 and the frame 11, which facilitates the holding of the drive assembly 4 by the receiving groove 121, and also avoid abrasion between the drive assembly 4 and any other part in the switch assembly 100 for the air conditioner indoor unit. Further, there can be multiple protruding slots 1211 and the racks 41, and multiple racks 41 drive the door 2 to move in the front-rear direction, which is relatively stable.


Optionally, as shown in FIGS. 3-8, the guiding groove 122 is formed at the side of the mounting part 12 facing the door 2. For example, as shown in FIG. 5, the guiding groove 122 extends substantially in the front-rear direction, which likely allows a considerable length of the guiding groove 122 in the front-rear direction of the mounting part 12, which facilitates the guiding groove 122 to guide the guiding part 3, and also allows the guiding groove 122 to have a better limiting effect on the guiding part 3. At the same time, the guiding groove 122 extending substantially in the horizontal direction also facilitates the cooperation of the guiding groove 122 and the guiding part 3.


In some embodiments of the present disclosure, as shown in FIGS. 5-9, the guiding groove 121 has a ring shape and is disposed around the outer side of the receiving groove 121. Thereby, the drive assembly 4 in the receiving groove 121 can protrude from the annular hole of the guiding groove 122 without affecting the cooperation of the guiding groove 122 with the guiding part 3. In addition, the annular guiding groove 122 can limit the guiding part 3 in the axial direction and the radial direction, so that the guiding groove 122 has better limiting effect on the guiding part 3, and the movement trajectory is more precise.


Further, as shown in FIGS. 5-8, the cross-sectional area of the guiding groove 122 gradually decreases in the direction from the door 2 to the door mounting plate 1, that is, the cross-sectional area of the guiding groove 122 reaches the maximum at the end close to the door 2, which results in easy engagement between the guiding part 3 and the guiding groove 122; the cross-sectional area of the guiding groove 122 reaches the minimum at the end near the door mounting plate 1, which results in closer engagement between the guiding part 3 and the guiding groove 122 when the guiding part 3 moves towards the door mounting plate 1 along the guiding groove 122, thus further enhancing the limiting effect of the guiding groove 122 on the guiding part 3, and facilitating control of the movement trajectory of the door 2. Here, the plane in which the cross section is located is a plane formed by straight lines extending in the up-down and the left-right direction as shown in FIG. 1.


Optionally, as shown in FIGS. 5-8, the guiding groove 122 is formed by an annular first wall 1221 and an annular second wall 1222 disposed around the receiving groove 121, and the second wall 1222 is sleeved around circumferential outer side of the first wall 1221. So, in some examples, when the guiding part 3 is engaged with the guiding groove 122, the guiding part 3 can slide along the outer wall surface of the first wall 1221, and in some other examples, the guiding part 3 can slide along the inner wall surface of the first wall 1222, and in some examples, the guiding part 3 slides between the inner wall surface of the second wall 1222 and the outer wall surface of the first wall 1221. The first wall 1221 is gradually inclined radially outward in a direction from the door 2 to the door mounting plate 1, and the second wall 1222 is gradually inclined radially inwards in a direction from the door 2 to the door mounting plate 1. So, the guiding groove 122 formed by the first wall 1221 and the second wall 1222 extends in the front-rear direction in a cross-sectional view as shown in FIG. 5, with the opening facing the horn of the guiding part 3, which leads to easier engagement between the guiding part 3 and the guiding groove 122, and reduces the risk of collide with the first wall 1221 or the second wall 1222 of the guiding groove 122.


In some embodiments of the present disclosure, as shown in FIGS. 3-5, the door 2 includes a baseplate 21 and a cover plate 22, and the cover plate 22 is disposed at a side of the baseplate 21 away from the door mounting plate 1, and the cover plate 22 is removable relative to the baseplate 21, wherein the guiding part 3 is disposed at a side of the baseplate 21 adjacent to the door mounting plate 1. That is, after the cover 22 is fitted to the baseplate 21, the cover 22 and the baseplate 21 can be separated. For example, the baseplate 21 and the cover plate 22 can be separated, the guiding part 3 can be mounted at the baseplate 21, and then the cover plate 22 can be mounted at the baseplate 21 to make the door 2 more beautiful, thus improving the mounting efficiency of the guiding part 3 and the door 2 without affecting the appearance of the door 2.


Further, as shown in FIGS. 3-5, a protrusion part 211 protruding toward the cover plate 22 is disposed at the central portion of the baseplate 21, and the side of the protrusion part 211 away from the cover plate 22 is provided with a mounting groove 2111, and the guiding part 3 is disposed in the mounting groove 2111. That is to say, the mounting groove 2111 is formed in the middle of the baseplate 21 and can extend toward the cover plate 22, the opening of the mounting groove 2111 faces the door mounting plate 1, and the guiding part 3 is mounted at the baseplate 21 through the mounting groove 2111.


Further, as shown in FIGS. 3-5, the guiding part 3 includes a bottom wall 31 and a peripheral wall 32 circumferentially disposed around the bottom wall 31, the bottom wall 31 and a portion of the peripheral wall 32 are received in the mounting groove 2111, and the peripheral wall 32 is movably disposed in the guiding groove 122. That is, the guiding part 3 is formed in a cylindrical shape with the opening facing the door mounting plate 1, and the bottom wall 31 of the guiding part 3 can protrude into the mounting groove 2111 and be mounted at the bottom wall of the mounting groove 2111, so that the extension length of the peripheral wall 32 of the guiding part 3 in the front-rear direction is increased, thus facilitating the engagement and the limitation between the guiding part 3 and the guiding groove 122, so that the movement trajectory of the door 2 can be better controlled.


In some examples of the disclosure, the baseplate 21 and the guiding part 3 are detachably connected. Thereby, the baseplate 21 and the guiding part 3 can be easily mounted and dismounted. For example, as shown in FIG. 5 and FIG. 6, a groove 311 is formed in the bottom wall 31 of the guiding part 3, and a snap protrusion 2112 is formed at a side of the protrusion part 211 facing the door mounting plate 1, enabling efficient mounting and dismounting between the bottom 21 and the guiding part 3 through the engagement between snap protrusion 2112 and groove 311.


In some embodiments of the present disclosure, the door assembly of the air conditioner indoor unit further includes a guide ring 6 disposed at an opening side of the guiding groove 122 facing the door 2, and the inner peripheral wall of the guide ring 6 gradually tilts inward radially in a direction towards the switch. Here, the inner peripheral wall refers to the inner wall surface of the guide ring 6 facing the guiding part 3 when the guiding part 3 is engaged with the guiding groove 122. That is, the guide ring 6 is disposed between the guiding groove 122 and the door 2, and as shown in FIG. 5, while the door 2 is moving forward and backward, the guiding part 3 can be engaged with the guide ring 6 so as to slide towards the guiding groove 122 along the inner wall surface of the guide ring 6, so that the guiding part 3 can be more easily fitted to the guiding groove 122. The inner wall surface of the guide ring 6 extends obliquely downward while the guide ring 6 is extending forward and backward, so that after the guiding part 3 enters the guiding groove 122 along the guide ring 6, the guide ring 6 can cooperate with the guiding groove 122 to jointly limit the guiding part 3, thereby better control the movement of the door 2.


Optionally, as shown in FIGS. 5-9, the guide ring 6 may extend from rear to the front, and in the front-rear direction, the length of the second wall 1222 plus guide ring 6 is greater than the length of the first wall 1221, therefore, the guide ring 6 can increase the guiding length of the guiding part 3 in the front-rear direction, thus facilitating the movement of the door 2 between the open position and the closed position. Further, when the door 2 is moving between the open position and the closed position, the guiding part 3 can always cooperate with the guide ring 6 to avoid the problem that the guiding part 3 may offset after sliding out of the guiding groove 122 during the moving process, leading to difficult future engagement with the guiding groove 122.


Optionally, the outer peripheral wall of the guiding part 3 is parallel to the inner peripheral wall of the guide ring 6. It should be noted that the outer peripheral wall of the guiding part 3 refers to the outer wall surface of the guide ring 6 facing the guiding part 3 when the guiding part 3 is engaged with the guiding groove 122. So, the outer wall surface of the guiding part 3 is parallel to the inner wall surface of the guide ring 6, thus enabling the guiding part 3 to better slide along the inner wall surface of the guide ring 6.


Optionally, the inner peripheral wall of the guide ring 6 is provided with a positioning protrusion 61, and the positioning protrusion 61 can reduce the fit clearance between the guide ring 6 and the guiding part 3, and further limit the guiding part 3, thus improving the limiting effect of the guide ring 6 on the guiding part 3, so as to further control the movement of the door 2 between the open position and the moving position, and the guiding part 3 can be prevented from shaking.
