The invention provides an indoor unit of an air conditioner, which can be selected as a floor type indoor unit of the air conditioner or a vertical hanging type indoor unit of the air conditioner and the like; the present invention is described by taking a floor type air conditioner indoor unit as an example, but the present invention is not limited thereto. The indoor unit of the air conditioner is provided with an air inlet, an air outlet and a heat exchange air duct communicated with the air inlet and the air outlet, and the air outlet usually extends along the vertical direction. The indoor unit of the air conditioner also typically includes an indoor heat exchanger disposed in the heat exchange duct, and the indoor heat exchanger is used for adjusting the temperature of indoor air, such as cooling or heating. The air-conditioning indoor unit also comprises a wind wheel arranged in the heat exchange air duct, and the wind wheel is used for driving air to flow; wherein, the wind wheel can be selected as a cross flow wind wheel and is arranged on the air outlet side of the indoor heat exchanger. When the indoor unit of the air conditioner works, the wind wheel drives indoor air to flow and drives the indoor air to enter the heat exchange air channel from the air inlet, and the flowing air flows to the air outlet after heat exchange of the indoor heat exchanger and is sent out through the air guide frame 10.
In an embodiment of the present invention, as shown in fig. 1 to 5, the indoor unit of an air conditioner further includes: the air guide frame 10 is rotatably arranged at the air outlet, and a mounting hole 11 is formed in the bottom of the air guide frame 10; the gear box 20 is arranged below the air guide frame 10; the rotating part 30 is rotatably installed on the gear box 20, and the upper end of the rotating part 30 protrudes out of the top of the gear box 20 and is fixedly matched with the installation hole 11 so as to drive the wind guide frame 10 to rotate; a plurality of bearings 40, an axis of the bearing 40 extending in a lateral direction, the plurality of bearings 40 being provided at intervals on a peripheral side of the rotor 30; the bearing 40 comprises an inner ring 41 and an outer ring 42 which can rotate relatively, the inner ring 41 is fixedly matched with the gear box 20, and the outer ring 42 is abutted to the bottom of the air guide frame 10; or, the inner ring 41 is fixedly matched with the wind guide frame 10, and the outer ring 42 abuts against the top of the gear box 20.
In this embodiment, the air guiding frame 10 is rotatably disposed at the air outlet of the air conditioning indoor unit, and the rotation axis of the air guiding frame 10 extends along the longitudinal direction to change the air supply direction of the air conditioning indoor unit in the horizontal direction. The gear box 20 is used for supporting the air guide frame 10, and specifically, the gear box 20 includes a bottom case and a top cover. The rotating member 30 is installed in the gear box 20, and the top of the rotating member 30 protrudes out of the top cover, so as to be fixedly matched with the wind guiding frame 10 and then drive the wind guiding frame 10 to rotate. The gravity of the wind guiding frame 10 directly acts on the rotating member 30, and if the rotating member 30 contacts the gear box 20 to form a frictional resistance, the wind guiding frame 10 increases the frictional resistance. The bearing 40 may be a ball bearing 40, and includes an inner ring 41 and an outer ring 42 coaxially disposed, and the inner ring 41 and the outer ring 42 are rotatable with each other by the balls. The number of the bearings 40 may be two, or 3 or more, and if the number of the bearings 40 is two, the two bearings 40 may be divided into two opposite sides in the circumferential direction of the rotating member 30. The bearing 40 is arranged between the wind guide frame 10 and the gear box 20, the installation mode can be that an inner ring 41 of the bearing 40 is fixedly matched with the wind guide frame 10, and the bottom of an outer ring 42 is in rolling contact with the gear box 20; the inner cavity of the bearing 40 and the top of the gear box 20 fixed on the gear box 20 can be also provided, and the top of the outer ring 42 is in rolling contact with the wind guide frame 10.
When the inner race 41 of the bearing 40 is fixed to the air guide frame 10, the gravity of the air guide frame 10 acts on the gear box 20 through the outer race 42, and since the outer race 42 is in rolling contact with the gear box 20, the friction force generated between the outer race 42 and the gear box 20 has little influence on the rolling of the outer race 42, and the air guide frame 10 can smoothly rotate. If the inner ring 41 of the bearing 40 is fixed to the top of the gear box 20, the gravity of the air guide frame 10 directly acts on the outer ring 42 of the bearing 40, and the outer ring 42 is in rolling contact with the air guide frame 10, so that the friction force between the air guide frame 10 and the outer ring 42 due to scraping has little influence on the rolling of the outer ring 42, and the air guide frame 10 can smoothly rotate. The two bearings 40 are respectively disposed on two sides of the rotating member 30 in the circumferential direction and are coaxially disposed, so that the two outer rings 42 roll to support the rotation of the wind guide frame 10, thereby improving the smoothness and stability of the rotation of the wind guide frame 10.
The air conditioner indoor unit of the invention supports the wind guide frame 10 to rotate by arranging the plurality of bearings 40 between the wind guide frame 10 and the gear box 20 and by the rolling contact of the outer ring 42 of the bearings 40 and the wind guide frame 10 or the gear box 20, thereby avoiding the direct contact friction between the wind guide frame 10 and the gear box 20, improving the smoothness and stability of the rotation of the wind guide frame 10 and reducing the noise.
It should be noted that, if directional indications (such as up, down, left, right, front, and back … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative positional relationship between the components, the movement situation, and the like in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indications are changed accordingly.
Specifically, as shown in fig. 1 and 2, a mounting ring 12 annularly disposed in the mounting hole 11 is protruded from a bottom of the air guide frame 10, a mounting post 121 is protruded from an outer peripheral wall of the mounting ring 12, the mounting post 121 is fixedly engaged with the inner ring 41, and a bottom of the outer ring 42 abuts against a top of the gear box 20. In this embodiment, the mounting ring 12 extends along the circumferential direction of the mounting hole 11, the mounting posts 121 are protruded from the two back sides of the mounting ring 12, and the inner rings 41 of the two bearings 40 are fixedly engaged with the mounting posts 121. After the rotating member 30 is matched with the mounting hole 11, the outer rings 42 of the two bearings 40 abut against the top of the gear box 20, thereby realizing the fixed mounting of the bearings 40 and the wind guide frame 10,
in practical application, as shown in fig. 2, the bottom of the outer ring 42 protrudes from the bottom of the mounting ring 12, and the bottom of the air guide frame 10 is provided with a yielding groove 13 corresponding to the top of the outer ring 42. In the embodiment, the bottom of the outer ring 42 protrudes from the bottom of the mounting ring 12, so that the mounting ring 12 is prevented from contacting the gear box 20, and the rotation of the air guide frame 10 is smoother. The avoiding groove 13 can prevent the outer ring 42 from directly contacting the bottom of the wind guide frame 10, so that the bottom of the outer ring 42 separates the wind guide frame 10 from the gear box 20, and a gap is formed between the top of the outer ring 42 and the wind guide frame 10, so that the rotation of the wind guide frame 10 can be effectively supported by the rolling contact of the outer ring 42 and the gear box 20, and the smoothness of the rotation of the wind guide frame 10 is improved.
In one embodiment, as shown in fig. 2, the outer peripheral wall of the mounting ring 12 is further protruded with protection ribs 122 located at both lateral sides of the bearing 40. In the embodiment, the protection ribs 122 are protruded from both lateral sides of each bearing 40, and the protection ribs 122 are used to ensure stable rolling of the outer ring 42, reduce the obstruction of the foreign objects to the rolling of the outer ring 42, and further improve the stability of the rotation of the air guide frame 10. The protective ribs 122 may be integrally formed with the mounting ring 12 to improve the connection strength and the production efficiency.
Specifically, as shown in fig. 1 and 2, the top of the gear box 20 is protruded with a guide ring 21 annularly provided to the rotating member 30, and the bearing 40 is located on the inner peripheral side of the guide ring 21. In the present embodiment, the guide ring 21 extends along the circumferential direction of the rotating member 30 to provide a limit guide for the bearing 40 and prevent the bearing 40 from shifting during rolling. When the bearing 40 is in contact with the guide ring 21, the bearing 40 is in line contact with the guide ring 21, so that the influence on the rolling of the outer ring 42 can be reduced, and the outer ring 42 can naturally turn along the guide ring 21, thereby enabling the rotation of the air guide frame 10 to be more stable.
In an embodiment, a plurality of mounting shafts are disposed on the top of the gear box 20, the mounting shafts are disposed at intervals on the periphery of the rotating member 30, the inner ring 41 is fixedly engaged with the mounting shafts, and the outer ring 42 abuts against the bottom of the wind guide frame 10. In the present embodiment, the axis of the mounting shaft extends in the transverse direction, and the inner ring 41 is fixedly engaged with the mounting shaft, i.e., the inner ring 41 is fixed relative to the gear box 20. The outer ring 42 abuts against the bottom of the wind guide frame 10, that is, the outer ring 42 is in rolling contact with the wind guide frame 10, so that the bearing 40 can separate the wind guide frame 10 from the gear box 20 and effectively support the wind guide frame 10 to rotate, thereby realizing the fixed installation of the bearing 40 and the gear box 20.
Specifically, the top of the outer ring 42 protrudes from the top of the rotating member 30, and a gap is formed between the bottom of the outer ring 42 and the top of the gear box 20. In the embodiment, the top of the outer ring 42 protrudes from the top of the rotating member 30, so that the gravity of the wind-guiding frame 10 acts on the bearing 40 and does not act on the rotating member 30, thereby reducing the stress load of the rotating member 30 and ensuring the stable rotation of the rotating member 30. The clearance between the outer ring 42 and the gear box 20 can prevent the outer ring 42 from directly contacting the gear box 20, so that the outer ring 42 can roll smoothly.
In practical application, a guide ring annularly arranged in the mounting hole 11 is convexly arranged at the bottom of the air guide frame 10, and the bearing 40 is located on the inner peripheral side of the guide ring. In the present embodiment, the guiding ring extends along the circumferential direction of the mounting hole 11 to perform a limiting guiding function on the bearing 40, so as to prevent the wind guiding frame 10 from being cheaper than the bearing 40 during the rotation process. When the guide ring is in contact with the bearing 40, the bearing 40 is in line contact with the guide ring, and the influence on the rotation of the outer ring 42 can be reduced, so that the rotation of the air guide frame 10 is more stable.
In an embodiment, as shown in fig. 1 and 2, a mounting table 14 is protruded from a bottom of the wind guide frame 10, and the mounting hole 11 is opened in the mounting table 14. In this embodiment, in combination with the above-described embodiment of the mounting ring 12, the mounting ring 12 may be annularly disposed on the mounting base 14. The mounting table 14 can increase the hole wall area of the mounting hole 11, thereby increasing the matching area of the mounting hole 11 and the rotating member 30, and enhancing the matching strength of the rotating member 30 and the wind-guiding frame 10.
The present invention further provides an air conditioner, which includes an outdoor unit and an indoor unit, and the specific structure of the indoor unit of the air conditioner refers to the above embodiments. The air conditioner outdoor unit is connected with the air conditioner indoor unit through a refrigerant pipe.
The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
