DETAILED DESCRIPTION

Embodiments of the present disclosure will be described in detail below. The embodiments described with reference to 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 the embodiments of the present disclosure will be described below with reference to FIGS. 1 to 22. The air conditioner indoor unit 100 may be a wall-mounted air conditioner indoor unit. In the following description of the present disclosure, for example, 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 and an outer air deflector 3.
As shown in FIGS. 2 to 4, 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, and the inner air deflector 2 is pivotable between a first closed position in the first accommodating space and a first open position where the air outlet 111 is open. The outer air deflector 3 is pivotable between a second closed position in the second accommodating space and a second open position where the second accommodating space is open. In a case where the inner air deflector 2 is at the first closed position and the outer air deflector 3 is at the second closed position, the inner air deflector 2 is located at a rear side of the outer air deflector 3 and is shielded by the outer air deflector 3.
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 on a front side of the housing 1, and the second accommodating space is located on a front side of the first accommodating space. The inner air deflector 2 is pivotally provided in the first accommodating portion 11 for controlling an opening and closing of the air outlet 111. The outer air deflector 3 is pivotally provided in the second accommodating portion 12, thereby reducing a dimension difference between the outer air deflector 3 and the inner air deflector 2. The inner air deflector 2 is located on the rear side of the outer air deflector 3, and in a case where both the inner air deflector 2 and the outer air deflector 3 are in a closed state, the outer air deflector 3 shields the inner air deflector 2. In this case, a front side surface of the outer air deflector 3 is flush with a front side 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 of the present disclosure, when a user faces the air conditioner indoor unit 100, a direction toward the user is referred to as "front", and a direction away from the user is referred to as "rear". Therefore, the second accommodating space is located on the front side of the first accommodating space, and in the case where both the inner air deflector 2 and the outer air deflector 3 are in the closed state, the outer air deflector 3 is located on the 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 pivots in the first accommodating portion 11, and the outer air deflector 3 pivots 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 on the rear side of the outer air deflector 3 and is shielded by the outer air deflector 3, which reduces the dimension difference between the outer air deflector 3 and the inner air deflector 2 and ensures an aesthetic appearance of the housing 1 of the air conditioner indoor unit 100.
According to some embodiments of the present disclosure, as shown in FIG. 3, 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, so as to form an airflow Coanda effect and improve an air blowing distance of the air conditioner indoor unit 100; moreover, it is possible to facilitate that air from the air outlet 111 is blown upward in a case where the outer air deflector 3 is opened and then falls freely to form a shower type blowing, thereby improving comfort of the user.
Further, according to some embodiments of the present disclosure, as shown in FIG. 3, the outer plate rear panel 38 is configured in a shape inclined toward the outer plate front panel 37 along a direction from a pivot end to a free end. That is, the outer plate rear panel 38 has an arc-shaped portion recessed toward the outer plate front panel 37, which further ensures the airflow Coanda effect, improves the air blowing distance of the air conditioner indoor unit 100, and further ensures that the air from the air outlet 111 is blown upward in the case where the outer air deflector 3 is opened, and then falls freely to form the shower type blowing, thereby improving the comfort of the user.
According to some embodiments of the present disclosure, as shown in FIGS. 16 to 19, an inner side of the outer plate front panel 37 is provided with a fixing plate 371, and the fixing plate 371 has a second through hole 372. The outer plate rear panel 38 has a sliding portion 35 and a slot. The sliding portion 35 is slidably provided with a sliding member 365. The sliding member 365 is provided with a sliding rod 361. An end of a rotating arm 43 has a first insertion hole 431, and the end of the rotating arm 43 is inserted into the slot. The sliding rod 361 passes through the first insertion hole 431 and the second through hole 372 sequentially to pivotally connect the rotating arm 43 to the outer air deflector 3. With such arrangement, a smooth pivoting of the outer air deflector 3 is effectively ensured, and a situation of jamming during the pivoting of the outer air deflector 3 is avoided.
Referring to FIGS. 3 and 8, the inner air deflector 2 is hollow inside, and includes an inner plate rear panel 22 and an inner plate front panel 21 connected to each other. The inner plate front panel 21 is configured as an arc-shaped panel protruding rearward, so as to form the airflow Coanda effect, and improve the air blowing distance of the air conditioner indoor unit 100; moreover, it is possible to facilitate that the air from the air outlet 111 is blown upward in the case where the inner air deflector 2 is opened, and then falls freely to form the shower type blowing, thereby improving the comfort of the user. As shown in FIG. 3, the inner plate rear panel 22 and the inner plate front panel 21 are both configured as arc-shaped panels protruding rearward, and have different radians. The radian of the inner plate rear panel 22 is greater than the radian of the inner plate front panel 21, thus effectively ensuring a strength of the inner air deflector 2.
According to some embodiments of the present disclosure, referring to FIG. 5, the housing 1 includes an outer cover 13, and a left side cover 131 and a right side cover 132 located on a left side and a right side of the outer cover 13 respectively. As shown in FIG. 5, the first accommodating portion 11 is located on the outer cover 13. By providing the first accommodating portion 11 on a front side of the outer cover 13, an installation space of the inner air deflector 2 is effectively ensured, which helps to lengthen a length of the inner air deflector 2, reduce the dimension difference between the inner air deflector 2 and the outer air deflector 3, and 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. With such arrangement, an installation space of the outer air deflector 3 is ensured. Optionally, in some embodiments, the housing 1 may further include a panel 15 and a base 16. The panel 15 is located on a side of the outer cover 13 (e.g., a right side shown in FIG. 3), and the base 16 is fixed to a lower end of the outer cover 13.
Optionally, in some embodiments, a thickness of an upper end of the inner air deflector 2 is greater than a thickness of a lower end thereof in a case where the inner air deflector 2 is at the first closed position. Referring to FIGS. 3 and 8, in a case where the inner air deflector 2 is closed, the thickness of the upper end thereof is greater than the thickness of the lower end thereof, which effectively ensures the strength of the inner air deflector 2 and prevents the inner air deflector 2 from cracking during pivoting. Herein, it will be noted that, in a case where the inner air deflector 2 is closed, an end of the inner air deflector 2 proximate to the exterior of the air conditioner indoor unit 100 and at a relatively high position is referred to as the "upper end" (i.e., the pivot end), and an end of the inner air deflector 2 proximate to the interior of the air conditioner indoor unit 100 and at a relatively low position is referred to as the "lower end" (i.e., the free end).
According to some embodiments of the present disclosure, as shown in FIG. 4, the first accommodating portion 11 includes a first arc panel 112, a first left side plate 113 and a first right side plate 114. The first arc panel 112 is located on a side of the housing 1, and the first arc panel 112 inclines rearward from bottom to top, which ensures that an arc shape of the first arc panel 112 is consistent with the inner air deflector 2, improves a fit degree between the inner air deflector 2 and the first arc panel 112 in a case where the inner air deflector 2 is closed, and reduces a gap between the inner air deflector 2 and the outer cover 13. The first left side plate 113 and the first right side plate 114 are respectively located at a left side and a right side of the first arc panel 112. The first left side plate 113, the first right side plate 114, and the first arc panel 112 define the first accommodating space, and the inner air deflector 2 is pivotally located in the first accommodating space.
Optionally, in some embodiments, as shown in FIG. 4, a first inner plate mounting column 1131 and a second inner plate mounting column 1141 are oppositely provided on the first left side plate 113 and the first right side plate 114, and both sides of the upper end of the inner air deflector 2 are pivotally connected to the first inner plate mounting column 1131 and the second inner plate mounting column 1141. Optionally, in an example shown in FIG. 5, an inner plate mounting hole may be formed on each of the first left side plate 113 and the first right side plate 114, an end of the first inner plate mounting column 1131 and an end of the second inner plate mounting column 1141 are each inserted and fixed in a corresponding inner plate mounting hole, and another end of the first inner plate mounting column 1131 and another end of the second inner plate mounting column 1141 are exposed and pivotally connected to the inner air deflector 2, thus effectively ensuring a fixing reliability of the inner air deflector 2.
Optionally, in some embodiments, as shown in FIG. 3, the upper end of the inner air deflector 2 is configured as an arc-shaped end, so as to be pivotally connected to the first accommodating portion 11, thus effectively ensuring that the inner air deflector 2 is pivotally fixed to the first accommodating portion 11. An extension length of the inner plate rear panel 22 is less than an extension length of the inner plate front panel 21, and a lower end of the inner plate front panel 21 is bent rearward and covers a lower end of the inner plate rear panel 22, thus effectively ensuring a smoothness of an air outlet surface of the inner plate front panel 21 (e.g., an upper end in FIG. 3), and improving an air outlet volume of the air outlet 111. A bending angle of the lower end of the inner plate front panel 21 is within a range of 30 to 80 degrees inclusive, optionally about 60 degrees, which is not limited thereto. With such arrangement, it may facilitate an integral molding of the inner plate rear panel 22 and the inner plate front panel 21, which makes the manufacturing process simple.
According to some embodiments of the present disclosure, as shown in FIGS. 3 and 5, the housing 1 further includes an inner plate mounting plate 14 provided on the outer cover 13, and a rear end of the inner plate mounting plate 14 is connected to a top portion of the first arc panel 112. The inner air deflector 2 is fixed on the inner plate mounting plate 14, a lower end of a front portion of the inner plate mounting plate 14 extends downwardly to form a fastener 142, and a top portion of the outer cover 13 has a clamping groove 143. The fastener 142 cooperates with the clamping groove 143, so that the inner plate mounting plate 14 is installed on the top portion of the outer cover 13, e.g., a front side of the top portion of the outer cover 13. However, it is not limited thereto. Optionally, a clamping groove 143 may be provided on the lower end of the front portion of the inner plate mounting plate 14, and a fastener 142 may be provided on the top portion of the outer cover 13. Thus, a stability of fixing of the inner plate mounting plate 14 is ensured through the cooperation of the fastener 142 and the clamping groove 143, which makes the manufacturing process simple. A front surface of the inner plate mounting plate 14 is inclined forward from bottom to top to define a top region of the first accommodating portion 11. Thus, the inner plate mounting plate 14 and the outer cover 13 may be injection-molded separately, so that the inner plate mounting plate 14 and the outer cover 13 may be easily demolded to facilitate the manufacturing and assembly.
Further, as shown in FIG. 5, the top portion of the first accommodating space of the first accommodating portion 11 is open, and the inner plate mounting plate 14 is provided on the top portion of the first accommodating portion 11, so as to define the top region of the first accommodating space, which may further ensure that the inner plate mounting plate 14 and the outer cover 13 can be injection-molded separately. As a result, the outer cover 13 and the inner plate mounting plate 14 may be easily demolded to facilitate the manufacturing and assembly.
According to some embodiments of the present disclosure, as shown in FIG. 5, a rear end of the inner plate mounting plate 14 is connected to the top portion of the outer cover 13, so that the inner plate mounting plate 14 and the top portion of the outer cover 13 define the top region of the first accommodating portion 11, thereby ensuring an installation space of the inner air deflector 2.
Further, as shown in FIGS. 2 and 5, a middle portion of the inner plate mounting plate 14 is provided with an inner plate pivot base 141, and the inner air deflector 2 has an inner plate rotating shaft, and the inner plate rotating shaft cooperates with the inner plate pivot base 141, so as to pivotally position the inner air deflector 2 on the inner plate mounting plate 14. With such arrangement, it may effectively ensure that the inner air deflector 2 pivots between the first closed position in the first accommodating space and the first open position where the air outlet 111 is open.
Further, in embodiments of the present disclosure, as shown in FIGS. 4 to 7, front sides of the left side cover 131 and the right side cover 132 have a left concave portion 1311 and a right concave portion 1321 respectively.
