The invention provides a rotating mechanism of an air outlet frame and a cabinet air conditioner provided with the rotating mechanism of the air outlet frame.

Here, referring to fig. 1, the rotation mechanism 10 of the air-out frame is installed for the air-out frame 30, and when the cabinet air conditioner is operated, the air-out frame can rotate along with the rotation mechanism 10 of the air-out frame to guide the air to different angles. The rotation angle of the air-out frame can be determined according to the user requirement, for example, the rotation angle is 60 °, 90 °, 120 °, 150 °, 180 ° or 360 °, so as to realize the large-angle rotation of the air-out frame 30.

In the embodiment of the present invention, referring to fig. 1, fig. 2 and fig. 3, a rotating mechanism 10 of an air-out frame includes a chassis 11, a first rolling member 12 and a turntable 13, where the chassis 11 has an upper surface and a lower surface, and a plurality of first mounting grooves 110 are arranged on an upper surface 11 a; the first rolling element 12 is arranged in the first mounting groove 110; the turntable 13 is positioned above the chassis 11 and supported by the first rolling member 12; and the rotating disc 13 is limited and mounted on the chassis 11, and the first rolling element 12 is used for the rotating disc 13 to rotate relative to the chassis 11.

Specifically, the cabinet air conditioner has a body 20, and a rotation mechanism 10 of the air-out frame is located between the body 20 and the air-out frame 30. The chassis 11 is mounted on the body 20, and the air outlet frame 30 is mounted on the rotary table 13. It should be understood that, the rotating mechanism 10 of the air-out frame has a through hole 11b (for example, a through hole 11b is formed in the middle of the chassis 11 and the rotary disc 13) for communicating the body 20 with the air-out frame, when the cabinet air conditioner is in operation, after the blower introduces air outside the cabinet air into the cabinet air, the air exchanges heat with the heat exchanger, then passes through the through hole 11b, and finally is led out by the air-out frame 30.

The rotation of the rotary disk 13 may be driven by a driving device, for example, a rack is disposed on the rotary disk 13, the driving device includes a motor and a gear disposed on the motor, and the gear is engaged with the rack to drive the rotary disk 13 to rotate. Of course, the driving device can also directly drive the air outlet frame to rotate.

During the assembly process, the chassis 11 is first mounted on the body 20, for example, fixedly connected to the inner wall of the body 20, the first rolling member 12 is then placed in the first mounting groove 110, the rotary disk 13 is placed on the chassis 11, and the air outlet frame 30 is then mounted on the rotary disk 13. In the process, the rotating mechanism 10 of the air outlet frame is convenient to rotate and assemble, the disassembly and the maintenance are simple, the replacement of parts is convenient, and the reliability is high.

In addition, in order to prevent the turntable 13 from deviating from the rotating track during rotation, the turntable 13 is mounted on the chassis 11 in a limited manner. For example, the lower surface of the rotary disk 13 is provided with an annular protrusion, the upper surface 11a of the chassis 11 is provided with an annular groove 112 corresponding to the protrusion, and the rotary disk 13 can rotate relative to the chassis 11 under the cooperation of the annular protrusion and the annular groove 112. There are various ways of securing the turntable 13 to the chassis 11, as will be explained in the following.

According to the technical scheme, the plurality of first rolling parts 12 are arranged on the base plate 11, so that the rotary table 13 can rotate relative to the base plate 11, the large-angle rotation of the air outlet frame 30 can be met, and the air supply range of the air conditioner is enlarged.

Referring to fig. 3, 4, 5 and 7, when the cabinet air conditioner is operated, impurities in air inevitably enter the first mounting groove 110 (the first mounting groove 110 has an opening, a groove bottom and side walls, the first mounting groove 110 has an upward opening, the groove bottom is disposed opposite to the opening, and the side walls connect the groove bottom and extend upward; the first mounting groove 110 may be a circular groove having one circular side wall, or the first mounting groove 110 may be a square groove having four side walls), for example, dust or other foreign materials, etc. In this way, the first rolling member 12 may be prevented from rolling, so that the friction of the turntable 13 is increased, which is not favorable for the rotation of the turntable 13. In this embodiment, in order to avoid the influence of dust or other impurities on the rolling of the first rolling member 12, a boss 111 is disposed at the bottom of the first mounting groove 110, a gap is formed between the boss 111 and at least one side wall of the first mounting groove 110, and the boss 111 bears the first rolling member 12. Even if dust enters the first mounting groove 110 due to long-term use of the cabinet air conditioner, a gap is formed between the boss 111 and at least one side wall of the first mounting groove 110, and the gap can contain the dust or other impurities, so that the interference of the dust or other impurities can be effectively avoided.

The boss 111 may be located at the middle of the bottom of the first mounting groove 110, or at the connection between the bottom and the side wall.

In this embodiment, referring to fig. 7, in order to facilitate dust to enter the gap at the fastest speed to avoid forming a dead angle region (dust is deposited at the boundary between the bottom and the sidewall), the gap formed between the boss 111 and the sidewall of the first mounting groove 110 is annularly disposed. In this way, even if a part of dust is deposited on the surface of the first rolling member 12, the dust on various positions on the surface of the first rolling member 12 can rapidly enter the gap during the rolling of the first rolling member 12, and the dust or foreign matters can be prevented from being deposited on the dead corner area.

The first rolling members 12 are individually placed in the first mounting groove 110, and the first rolling members 12 may be ball-shaped balls, and the plurality of ball-shaped balls jointly support the turntable 13, and roll together when the turntable 13 rotates, so that the turntable 13 rotates.

Referring to fig. 2 and 3, in the above embodiment, the rotary plate 13 is rotatable with respect to the base plate 11, and the shape of the rotary plate 13 may be a semicircular arrangement, an annular arrangement, an arc arrangement, or the like, in which the through hole 11b is formed in the middle. Since the first rolling members 12 are disposed on the upper surface 11a, in order to facilitate the rotation of the turntable 13, the first rolling members 12 are prevented from interfering with the edge of the turntable 13, so as to affect the rotation of the turntable 13, and in the embodiment, the turntable 13 is preferably disposed in a ring shape. The chassis 11 may have various shapes, and the shape thereof may be substantially equivalent to the turntable 13. But also to facilitate rotation of the turntable 13, the chassis 11 is preferably arranged annularly.

With continued reference to fig. 3 and 7, in a preferred embodiment, the first rolling elements 12 may also be rollers arranged in a cylindrical manner, which rollers extend in the radial direction of the chassis 11. For spherical ball, the contact surface of roller and carousel 13 is bigger, and when carousel 13 was placed on the roller, carousel 13 was more steady, was difficult for rocking, and the rotation effect is better.

Referring to fig. 3, in a preferred embodiment, in order to limit the rotation of the rotary table 13 on the chassis 11, the upper surface 11a is protruded with a surrounding plate 14 arranged along the circumferential direction of the chassis 11, and the surrounding plate 14 is sleeved on the outer circumference of the rotary table 13 or sleeved by the inner ring of the rotary table 13. For example, a shroud 14 is provided on the inner periphery of the chassis 11, and the turntable 13 is fitted around the shroud 14. For another example, a shroud 14 is disposed around the outer periphery of the chassis 11, and the shroud 14 covers the turntable 13. The enclosure 14 is arranged to define the rotation path of the turntable 13 and to prevent the turntable 13 from deviating from the chassis 11 during rotation.

Referring to fig. 3 and 6, in the above embodiment, during the rotation of disk 13, enclosing plate 14 generates friction force on disk 13, thereby affecting the rotation of disk 13. In this embodiment, in order to make the rotation of the rotary disk 13 smoother, a second mounting groove 140 is disposed on a side wall of the enclosure plate 14 facing the rotary disk 13, and a second rolling member 15 for rotating the rotary disk 13 is disposed in the second mounting groove 140. In this way, when the rotary disk 13 rotates, the second rolling member 15 rolls, so that the sliding friction is replaced by the rolling friction, and the friction force applied when the rotary disk 13 rotates is greatly reduced.

Referring to fig. 3 and 6, considering that the cabinet air conditioner is in operation, the magazines in the air inevitably enter the second mounting groove 140, such as dust or other impurities, and thus the second rolling members 15 may be prevented from rolling, so that a large friction force is generated on the rotary plate 13, and the rotation of the rotary plate 13 is not facilitated. In this embodiment, an annular groove 112 is formed in a side wall of the second mounting groove 140 (the second mounting groove 140 also has an opening, a groove bottom, and side walls, the second mounting groove 140 is open toward the rotary plate 13, the groove bottom is opposite to the opening, the side walls are located between the groove bottom and the opening, the second mounting groove 140 may be a circular groove having an annular side wall, the first mounting groove 110 may be a square groove having four side walls, and the side wall of the second mounting groove 140 surrounded by the annular groove 112 supports the second rolling element 15. Therefore, when dust enters the second mounting groove 140, the annular groove 112 can receive dust or other impurities due to the existence of the annular groove 112, so that interference of the dust or other impurities can be effectively avoided. The second rolling elements 15 may be arranged spherically or cylindrically.

In one embodiment, with continued reference to fig. 6, the second rolling member 15 is provided in a cylindrical shape extending downward from the top. Therefore, the contact surface between the second rolling piece 15 and the side wall of the rotating disk 13 is large, the rotating disk 13 is not easy to shake, and the rotation is more stable.

Referring to fig. 2 and 3, the chassis 11 is to be fixed to the body 20 of the cabinet, and the enclosure 14 is disposed at the outer periphery of the chassis 11 to facilitate the fixing of the chassis 11, for example, the enclosure 14 is integrally formed with the chassis 11, and the chassis 11 is connected to the body 20. On the other hand, if the enclosure 14 is arranged on the inner periphery of the chassis 11, the perimeter of the enclosure 14 is smaller (compared with the enclosure 14 arranged on the outer periphery of the chassis 11), the second mounting groove 140 is arranged on the inner wall of the enclosure 14, the rigidity of the enclosure 14 is greatly influenced, and when the rotary disk 13 rotates, the enclosure 14 is pressed, so that the enclosure 14 may be cracked; further, since the circumferential length of the apron 14 provided on the inner circumferential edge of the chassis 11 is short, a large number of second rollers 15 cannot be provided, and the rotational resistance of the turntable 13 is large due to the small number of second rollers 15. Therefore, in the present embodiment, the enclosing plate 14 is disposed at the outer periphery of the chassis 11.

Referring to fig. 2, it is contemplated that turntable 13 may not be stable enough to be retained on chassis 11 by enclosure 14, because turntable 13 may be dislodged from chassis 11 during rotation if turntable 13 jolts, thereby causing an accident. On the basis of the above embodiment, in order to further enhance the reliability of installing the rotating disc 13 on the chassis 11, an annular cover plate 16 extending along the periphery of the enclosing plate 14 is installed at the upper end of the enclosing plate 14, and the rotating disc 13 is limited between the chassis 11 and the annular cover plate 16. In this way, the turntable 13 is restricted in both the lateral and longitudinal directions, and the reliability when the turntable 13 is rotated is higher.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all equivalent structural changes made by using the contents of the present specification and the drawings, or any other related technical fields, which are directly or indirectly applied to the present invention, are included in the scope of the present invention.
