Example 1
As shown in fig. 1-7, the indoor unit of the air conditioner comprises a casing, wherein the front surface of the casing is combined with a front panel 1, and an air outlet 10 is arranged on the front panel 1; an air inlet is formed in the shell; the casing is internally provided with a volute 2, a fan is arranged in the volute 2, and a heat exchanger is arranged between the fan and the air inlet. Under the action of the fan, air enters from the air inlet and passes through the heat exchanger; air passing through the heat exchanger is discharged into the room through the air outlet 10 by a fan.
The shell is provided with a driving mechanism 3 and a sliding door component 4; the driving mechanism 3 drives the sliding door assembly 4 to slide in the peripheral direction relative to the front panel 1, thereby opening or closing the air outlet 10 on the front panel 1.
As shown in fig. 1, the sliding door assembly 4 includes a sliding door 5, and racks 6 fixed to upper and lower ends of the sliding door 5; the driving mechanism 3 is fixed with the front panel 1 of the air conditioner, and the driving mechanism 3 is matched with the rack 6 and drives the rack 6 to slide relative to the peripheral direction of the front panel 1. The driving mechanism 3 comprises a motor and a gear, the motor is preferably a stepping motor, and the driving mechanism has the advantages of large torque and stable and reliable operation, and can reduce shaking when the sliding door 5 slides. The gear is provided on the output shaft of the motor, the gear rotates on the horizontal plane, and the gear is engaged with the rack 6, whereby the rack 6 can be driven to slide when the gear rotates. The rack 6 is arc-shaped, and a plurality of first teeth which are arranged at intervals along the length direction of the rack 6 are arranged on one side of the gear, and the integral radian of the rack 6 is consistent with the radian of the sliding door 5. Second teeth meshed with the first teeth are uniformly distributed on the circumference of the gear. Thereby, the motor of the driving mechanism 3 drives the gear to rotate, and the second teeth on the gear are meshed with the first teeth on the rack 6 and drive the meshing strip to move relative to the peripheral direction of the front panel 1; i.e. the sliding door 5 is moved with respect to the circumferential direction of the front panel 1, thereby opening or closing the air outlet 10 on the front panel 1.
The front panel 1 is provided with a rolling assembly 8, and the rolling assembly 8 is positioned at one side close to the sliding door assembly 4; i.e. the rolling assembly 8 is located between the sliding door assembly 4 and the front panel 1. The rolling assembly 8 includes a roller 81, and a rotation plane of the roller 81 is parallel to a direction of the outer periphery of the front panel 1. A guide strip 7 is arranged on one side of the sliding door assembly 4 (the sliding door 5 or the rack 6) close to the front panel 1; the guide bars 7 are provided in the direction of the outer periphery of the front panel 1 and correspond to the rollers 81 on the front panel 1. The roller 81 rolls along the guide strip 7. In the present embodiment, when the roller 81 contacts the guide bar 7, the roller 81 can roll with respect to the guide bar 7, i.e., the roller 81 can roll on the sliding door assembly 4 after contacting the sliding door assembly 4. Wherein the rotation plane of the roller 81 is parallel to the direction of the outer circumference of the front panel 1, so that when the roller 81 contacts the sliding door assembly 4, the rotation direction of the roller 81 can be adapted to the movement direction of the sliding door 5, thereby facilitating the rolling of the roller 81 relative to the guide bar 7 when the sliding door 5 slides relative to the front panel 1.
The rolling assembly 8 comprises a connecting part 82, one end of the connecting part 82 is connected with the front panel 1, and the other end of the connecting part 82 is provided with a roller 81; and the roller 81 is provided at the front side of the front panel 1. The connection portion 82 is provided to ensure stability of the rolling assembly 8 mounted on the front panel 1, and to ensure that the rolling assembly 8 can maintain a stable state after contacting the sliding door assembly 4, i.e., can stably roll on the sliding door assembly 4.
In this embodiment, in the case that the sliding door 5 is operating normally, there is no space between the roller 81 and the guide bar 7; i.e. without deformation of the sliding door 5, there is no distance between the roller 81 and the guide strip 7.
In the present embodiment, in the case where the sliding door 5 is operating normally, the roller 81 is abutted against the guide bar 7, and the rolling member 8 is brought into contact with the guide bar 7 on the sliding door assembly 4, at which time the sliding door 5 can slide stably with respect to the front panel 1 to selectively open or close the opening. The contact between the roller 81 and the guide bar 7 can improve the sliding stability of the sliding door 5.
In addition, when the sliding door 5 is deformed in a special case, since the roller 81 is abutted against the guide bar 7 on the sliding door assembly 4 (the sliding door 5 or the rack 6), a gap between the sliding door assembly 4 and the front panel 1 can be ensured to effectively limit the deformation amount of the sliding door 5. At this time, the rolling member 8 rolls with respect to the guide bar 7 by the roller 81 to achieve the rolling of the rolling member 8 with respect to the sliding door assembly 4 and to avoid friction or collision between the sliding door assembly 4 and the front panel 1.
The sliding door assembly 4 provided in this embodiment can make the sliding door assembly 4 contact with the front panel 1 through the rolling assembly 8 disposed on the front panel 1 and the guiding strip 7 when sliding relative to the front panel 1, i.e. the relative movement mode of the contact portion between the sliding door assembly 4 and the front panel 1 is changed into a rolling mode, which avoids the damage caused by friction or direct collision between the sliding door assembly 4 and the front panel 1, and ensures that the sliding door 5 can slide stably relative to the front panel 1, and the service life of the sliding door 5 can be prolonged.
In addition, in the present embodiment, a plurality of rolling assemblies 8 are disposed on the front panel 1, and the plurality of rolling assemblies 8 are disposed on the front panel 1 at intervals, so that the plurality of rolling assemblies 8 provide protection to the front panel 1 throughout, and friction or collision between the sliding door 5 and the front panel 1 is avoided.
In addition, the guide bar 7 is provided with a convex rib, the convex rib is matched with the side surface of the roller 81, and the roller 81 rolls along the convex rib. Further, the two convex ribs are arranged in parallel along the extending direction of the guide strip, and the roller rolls along the end surfaces of the two convex ribs; the plurality of convex ribs are arranged, so that the processing and the forming are convenient on one hand; on the other hand, the roller can be limited in multiple axial directions so as to improve the rolling stability.
Further, an upper barrier strip is arranged on the upper side of the guide strip 7, and a lower barrier strip is arranged on the lower side of the guide strip; at least part of the rollers are positioned between the upper barrier strip and the lower barrier strip so as to limit the rollers along the direction of the rotation axis of the rollers, thereby ensuring the effectiveness of rolling and effectively avoiding rolling failure caused by separation of the rollers and the guide strips.
The sliding door 5 provided in this embodiment can make the manner of relative movement between the sliding door assembly 4 (sliding door 5 or rack 6) and the front panel 1 which are abutted by rolling contact with the guide bar 7 through the rolling assembly 8 provided on the front panel 1 when sliding relative to the front panel 1 becomes the rolling manner, thereby avoiding damage caused by friction or direct collision between the sliding door 5 or rack 6 and the front panel 1, ensuring that the sliding door 5 can slide stably relative to the front panel 1, and prolonging the service life of the sliding door 5.
Example two
The present embodiment is the same as the first embodiment in principle, and differs in that: in the case of normal operation of the sliding door 5, there is a space between the roller 81 and the guide bar 7, i.e., in the case where the sliding door assembly 4 (sliding door 5 or rack 6) is not deformed, there is a space between the roller 81 and the guide bar 7.
In the present embodiment, in the case where the sliding door 5 is normally operated, there is a space between the roller 81 and the guide bar 7, that is, the rolling member 8 does not come into contact with the sliding door assembly 4 (the sliding door 5 or the rack 6), and at this time, the sliding door 5 can be stably slid with respect to the front panel 1 to selectively open or close the opening.
In addition, when the sliding door assembly 4 (the sliding door 5 or the rack 6) is deformed under special conditions, the rolling assembly 8 can roll relative to the sliding door 5 or the rack 6 by abutting the roller 81 on the guide strip 7 on the sliding door assembly 4 (the sliding door 5 or the rack 6) and rolling relative to the guide strip 7 by the roller 81, and the function of friction or collision between the sliding door 5 or the rack 6 and the front panel 1 is avoided. At the same time, a gap between the sliding door assembly 4 (sliding door 5 or rack 6) and the front panel 1 can be ensured, and the deformation amount of the sliding door assembly 4 (sliding door 5 or rack 6) can be effectively limited. At the same time, the sliding stability of the sliding door 5 can be improved.
The sliding door 5 provided in this embodiment can be deformed when the sliding door assembly 4 (sliding door 5 or rack 6) is slid relative to the front panel 1, and can be made to roll by rolling contact between the rolling assembly 8 provided to the front panel 1 and the guide bar 7, i.e., the manner of relative movement between the sliding door assembly 4 (sliding door 5 or rack 6) and the front panel 1 can be made to roll, which avoids damage caused by friction or direct collision between the sliding door assembly 4 (sliding door 5 or rack 6) and the front panel 1, and ensures that the sliding door 5 or rack 6 can stably slide relative to the front panel 1, and can prolong the service life of the sliding door 5.
