The embodiments of the present disclosure will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary, and the embodiments of the present disclosure will be described in detail below.
An air conditioner indoor unit 100 according to embodiments of the present disclosure will be described below with reference to FIGS. 1 to 23. The air conditioner indoor unit 100 may be a wall-mounted air conditioner indoor unit. The following description of the present disclosure will be described by taking an example in which the air conditioner indoor unit 100 is the wall-mounted air conditioner indoor unit.
As shown in FIGS. 1 to 8, the air conditioner indoor unit 100 according to the embodiments of the present disclosure includes a housing 1, an inner air deflector 2, an outer air deflector 3 and an outer driving device 4.
As shown in FIGS. 2 and 3, the housing 1 includes a first accommodating portion 11 having a first accommodating space and a second accommodating portion 12 having a second accommodating space. The first accommodating portion 11 has an air outlet 111 (as shown in FIG. 4), and the second accommodating space is located at a front side of the first accommodating space. The inner air deflector 2 is pivotally disposed in the first accommodating space, and the outer air deflector 3 is pivotally disposed in the second accommodating space. Two outer driving devices 4 are respectively disposed at a left side and a right side of the housing 1 to drive the outer air deflector 3 to rotate between a second closed position and a second open position.
As shown in FIG. 3, the first accommodating portion 11 having the first accommodating space and the second accommodating portion 12 having the second accommodating space are located at a front side of the housing 1, and the second accommodating space is located at the front side of the first accommodating space. The inner air deflector 2 is rotatably disposed in the first accommodating portion 11 for controlling opening and closing of the air outlet 111, and the outer air deflector 3 is rotatably disposed in the second accommodating portion 12, thereby reducing a difference between a size of the outer air deflector 3 and a size of the inner air deflector 2. The inner air deflector 2 is located at a rear side of the outer air deflector 3, and in a case where the inner air deflector 2 and the outer air deflector 3 are both in a closed state, the outer air deflector 3 shields the inner air deflector 2. In this case, a front surface of the outer air deflector 3 is flush with a front surface of the housing 1, which effectively ensures an aesthetic appearance of the air conditioner indoor unit 100. Herein, it will be noted that, in the description, when a user faces the air conditioner indoor unit 100, a direction toward the user is referred to as "front", and conversely, a direction away from the user is referred to as "rear". Therefore, the second accommodating space is located at the front side of the first accommodating space, and in the case where the inner air deflector 2 and the outer air deflector 3 are both in the closed state, the outer air deflector 3 is located at a front side of the inner air deflector 2.
For the air conditioner indoor unit 100 according to the embodiments of the present disclosure, the housing 1 has the first accommodating portion 11 and the second accommodating portion 12; the inner air deflector 2 rotates in the first accommodating portion 11, and the outer air deflector 3 rotates in the second accommodating portion 12; in the case where the inner air deflector 2 and the outer air deflector 3 are closed, the inner air deflector 2 is located at the rear side of the outer air deflector 3, and is shielded by the outer air deflector 3. As a result, the difference between the size of the outer air deflector 3 and the size of the inner air deflector 2 is reduced, and an aesthetic appearance of the housing 1 of the air conditioner indoor unit 100 is ensured.
According to some embodiments of the present disclosure, the housing 1 includes an outer cover 13, and a left side cover 131 and a right side cover 132 that are respectively disposed at a left side and a right side of the outer cover 13. As shown in FIG. 5, the first accommodating portion 11 is disposed on the outer cover 13. By providing the first accommodating portion 11 at a front of the outer cover 13, it is possible to effectively ensure mounting space of the inner air deflector 2, to facilitate to increase a length of the inner air deflector 2, to reduce the difference between the size of the inner air deflector 2 and the size of the outer air deflector 3 is reduced, and to improve an air guiding effect. The second accommodating portion 12 is jointly constituted by the outer cover 13, the left side cover 131 and the right side cover 132, thereby ensuring mounting space of the outer air deflector 3.
In some optional embodiments, referring to FIG. 3, the housing 1 may further include a panel 15 and a base 16. The panel 15 is located at a side of the outer cover 13 (e.g., a right side in FIG. 3), and the base 16 is fixed to a lower end of the outer cover 13.
As shown in FIGS. 12 and 13, according to some embodiments of the present disclosure, the air conditioner indoor unit 100 further includes two outer driving devices 4. The two outer driving devices 4 are respectively disposed at the left side and the right side of the housing 1 to drive the outer air deflector 3 to rotate between the second closed position and the second open position. In some specific examples, as shown in FIGS. 14 and 15, each outer driving device 4 includes a motor 41, a connecting rod 42 and a rotating arm 43. The motor 41 is mounted at a side portion of the outer cover 13. The connecting rod 42 is connected to the motor 41, and is driven to rotate by the motor 41. An end of the rotating arm 43 is pivotally connected to the connecting rod 42, and the other end of the rotating arm 43 is pivotally connected to the outer air deflector 3.
In some optional embodiments, referring to FIG. 14, the outer driving device 4 further includes a transmission assembly 45. The transmission assembly 45 is disposed between the motor 41 and the connecting rod 42, and includes a plurality of gears engaged with each other to adjust driving force output by the motor 41 to the connecting rod 42.
For example, in examples shown in FIGS. 12 to 15, each outer driving device 4 further includes a connecting rod housing 44; the motor 41 is connected to the transmission assembly 45, the transmission assembly 45 is connected to the connecting rod 42, and the connecting rod 42 is rotatably connected to the rotating arm 43; the connecting rod 42 and the rotating arm 43 are disposed in the connecting rod housing 44, and the other end of the rotating arm 43 extends out of the connecting rod housing 44, and is pivotally connected to the outer air deflector 3. The motor 41 may also be directly connected to the connecting rod 42, but a large driving force of the motor is required. Through the connection between the motor 41 and the transmission assembly 45, the transmission assembly 45 may connect to the connecting rod 42 and amplify the driving force of the motor, thereby reducing costs of the motor 41.
In some optional embodiments, referring to FIG. 15, the transmission assembly 45 includes a first gear 451, a second gear 452, and a third gear 453 and a fourth gear 454 engaged with each other. The first gear 451 is sleeved on a motor shaft of the motor 41, and the second gear 452 is connected to a rotating shaft of the connecting rod 42 to drive the connecting rod 42 to rotate. The third gear 453 is engaged with the first gear 451, and the fourth gear 454 is engaged with the second gear 452, thereby effectively ensuring transmission efficiency of the transmission assembly 45.
Further optionally, an outer diameter D1 of the first gear 451, an outer diameter D2 of the second gear 452, an outer diameter D3 of the third gear 453, and an outer diameter D4 of the fourth gear 454 satisfy that D4 is less than D1, D1 is less than D2, and D2 is less than D3 (D4 < D1 < D2 < D3). With this arrangement, it is easy to amplify the driving force of the outer driving device 4 and reduce the cost of the motor 41. Of course, the present disclosure is not limited thereto. The number of the gears used in the transmission assembly 45 and a ratio among the outer diameters of the gears may also be determined according to a specific design.
In some further embodiments of the present disclosure, referring to FIG. 13 and in combination with FIGS. 16 to 19, an inner surface of the outer air deflector 3 has sliding portions 35. As shown in FIG. 17, left and right ends of the inner surface of the outer air deflector 3 are each provided with a sliding portion 35. The sliding portion 35 is slidably provided with a sliding member 36, and the sliding member 36 has a sliding rod 361. The other end of the rotating arm 43 has an insertion hole 431, and the sliding rod 361 is rotatably inserted into the insertion hole 431. As a result, it is possible to effectively ensure flexibility of the sliding rod 361 and the rotating arm 43, and support of the rotating arm 43 when the outer air deflector 3 is opened.
In some specific embodiments, as shown in FIGS. 17 to 20, the sliding member 36 is plate-shaped, but is not limited thereto. A surface of the sliding member 36 facing the outer air deflector 3 has a positioning groove 362, and the sliding portion 35 has a positioning protrusion 351. Referring to FIG. 17, the sliding portion 35 is provided with two positioning protrusions 351, and the two positioning protrusions 351 are opposite in an up-down direction. Through sliding of the positioning protrusions 351 in the positioning groove 362, sliding of the sliding member 36 on the sliding portion 35 is achieved. Thus, the sliding member 36 drives the outer air deflector 3 to rotate, and manufacturing process is simple.
As shown in FIG. 19, a positioning portion 363 is disposed at a side of the sliding member 36 away from an air deflector, that is, the positioning portion 363 is disposed at a side of the sliding member 36 facing an interior of the air conditioner indoor unit 100. An extension axis of the positioning portion 363 is parallel to the sliding member 36, and the positioning groove 362 is defined by the positioning portion 363 and the sliding member 36. In this way, fixing reliability of the sliding member 36 is effectively ensured, materials are saved, and costs are reduced.
Further, two limiting strips 364 are disposed at the side of the sliding member 36 away from the air deflector. The two limiting strips 364 are perpendicular to the extension axis of the positioning portion 363, and are disposed at both ends of the positioning groove 362 to limit positions of the positioning protrusions 351 in the positioning groove 362.
In some optional embodiments, as shown in FIG. 19, the positioning portion 363 includes an extension column 3631 and two extension pieces 3632. A cross section of the extension column 3631 substantially has a circular shape, and an end of the extension column 3631 is flush with the sliding member 36. That is, in FIG. 19, a left end of the extension column 3631 is flush with a left end of the sliding member 36. The sliding rod 361 is coaxially connected to an end of the extension column 3631, and the two extension pieces 3632 are disposed parallel to each other at both sides of the extension column 3631, and extend from the sliding member 36 in a direction away from the air deflector. That is to say, the two extension pieces 3632 extend toward the interior of the air conditioner indoor unit 100, and a distance between the two extension pieces 3632 is smaller than a diameter of the extension column 3631. As a result, it is possible to prevent the extension column 3631 from falling off, and to ensure fixing reliability of the extension column 3631. The positioning groove 362 is defined by the extension pieces 3632 and the sliding member 36.
Referring to FIGS. 17 and 19, when the outer air deflector 3 and the outer driving device 4 are mounted, the sliding member 36 moves toward a center of the outer air deflector 3. After the sliding rod 361 is aligned with a hole in a side plate of the outer air deflector 3, the sliding member 36 is pushed toward the connecting rod 42, so that the connecting rod 42 is hinged with the outer air deflector 3. During disassembly, the sliding member 36 may be pushed in a direction away from the connecting rod 42 with force. Specifically, as shown in FIG. 19, a back surface of the sliding member 36 is provided with the positioning portion 363, and the positioning groove 362 is defined by the positioning portion 363 and a side surface of the sliding member 36. Left and right ends of the positioning groove 362 are provided with the limiting strips 364, and an upper edge and a lower edge of the sliding portion 35 on a rear side plate of the outer air deflector 3 are provided with the positioning protrusions 351. During mounting, the positioning protrusions are located in the positioning groove 362, and the connection between the rotating arm 43 and the outer air deflector 3 is achieved through left and right sliding of the sliding member 36 on the sliding portion 35.
In some optional embodiments, the sliding rod 361 and the extension column 3631 are metal pieces, the sliding member 36 and the extension pieces 3632 are plastic pieces, and the sliding rod 361, the extension column 3631, the sliding member 36 and the extension pieces 3632 are integrally formed by means of injection molding. Therefore, strength of the sliding rod 361 and the extension column 3631 is ensured, assembly is easy, and manufacturing process is simple.
As shown in FIG. 5, according to some embodiments of the present disclosure, a left recessed portion 1311 and a right recessed portion 1321 are respectively disposed at a front side of the left side cover 131 and a front side of the right side cover 132. After the left side cover 131 and the right side cover 132 are assembled to the outer cover 13, the left recessed portion 1311, the right recessed portion 1321 and the outer cover 13 jointly define the second accommodating portion 12. An outer plate mounting column 1312 is further disposed at each of the front side of the left side cover 131 and the front side of the right side cover 132, and a lower end of the outer air deflector 3 is pivotally connected to the outer plate mounting column 1312. Referring to FIGS. 4 to 7, the left side cover 131 and the right side cover 132 are respectively fixed to a left end and a right end of the outer cover 13, and an outer plate mounting column 1312 is further disposed at each of the front side of the left side cover 131 and the front side of the right side cover 132. The lower end of the outer air deflector is pivotally connected to the outer plate mounting column 1312. The lower end of the outer air deflector 3 is pivotally connected to the outer plate mounting column 1312, and the outer air deflector 3 is pivotally fixed in the second accommodating space, so that the mounting space of the outer air deflector 3 is ensured, and the outer air deflector 3 is easy to be installed.
According to some specific embodiments of the present disclosure, as shown in FIGS. 3 and 21, the outer air deflector 3 is hollow inside, and includes an outer plate rear panel 38 and an outer plate front panel 37 connected to each other. The outer plate rear panel 38 has an arc-shaped plate protruding toward the outer plate front panel 37. As a result, an airflow Coanda effect is formed, and an air supply distance of the air conditioner indoor unit 100 is increased. Moreover, it is possible to facilitate that air from the air outlet 111 is blown upward and then falls freely to form shower-style blowing when the outer air deflector 3 is opened, and in turn, to improve comfort of the user.
