[0044] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0045] Combination Figure 1-8 As shown, an embodiment of the present disclosure provides a housing assembly 100 of an air conditioner indoor unit.

[0046] The air conditioner includes an indoor unit and an outdoor unit connected by a connection pipe, the indoor unit includes a housing assembly 100, an indoor heat exchanger and a fan, the housing assembly 100 defines an air duct, the indoor heat exchanger and the fan are located in the air duct, and the housing assembly 100 is provided with an air inlet 11 and an air outlet. Under the action of the fan, air enters the air duct through the air inlet 11 and flows out through the air outlet.

[0047] The housing assembly 100 includes a panel 2 and an air inlet grille 1 .

[0048] The panel 2 is provided with a mounting hole; the air inlet grille 1 is provided in the mounting hole and can move relative to the panel 2 between a closed position closing the mounting hole and an open position opening the mounting hole, wherein the air inlet grille 1 defines an air inlet 11 .

[0049] When the air inlet grille 1 needs to be cleaned, the air inlet grille 1 is driven to move to the open position. After the cleaning is completed, the air inlet grille 1 is driven to return to the closed position. At this time, the air conditioner can work normally.

[0050] The panel 2 is provided with a connecting portion 21 , and the housing assembly 100 further includes a mounting structure 3 , which cooperates with the connecting portion 21 to connect the air inlet grille 1 with the panel 2 .

[0051] like Figure 7 As shown, the mounting structure 3 includes a mounting portion 31 and a connecting and matching portion 32 .

[0052] The air inlet grille 1 includes a first end 13 and a second end 14. The second end 14 is arranged opposite to the first end 13.

[0053] The mounting structure cooperates with the connecting portion to connect the air inlet grille to the panel. The mounting structure includes a mounting portion, which is disposed at the first end and can move relative to the air inlet grille in the direction of a line between the first end and the second end. When the air inlet grille moves toward the open position, the mounting portion moves relative to the air inlet grille in the direction from the second end to the first end. Figures 1 to 7 In the case of Figures 9 to 12 In the case of an engine failure, the air inlet grilles are in the closed position.

[0054] The mounting portion 31 is movably connected to the air inlet grille 1 so that the mounting portion 31 can be moved relative to the direction of the line between the first end and the second end of the air inlet grille 1 (eg Figure 1 The up and down directions in Fig.10 The up and down directions in Fig.11 In the process of the air inlet grille 1 moving toward the open position, the mounting portion 31 moves in the direction from the second end to the first end relative to the air inlet grille 1. In other words, the air inlet grille 1 moves in the direction from the first end to the second end relative to the mounting portion 31. In this way, in addition to the movement of the air inlet grille 1 toward the open position driven by the operator holding the air inlet grille 1, the air inlet grille 1 can also further move in the direction from the first end to the second end due to the sliding connection with the mounting portion 31, thereby increasing the distance between the air inlet grille 1 and the panel 2 on the line connecting the second end and the first end. In this way, the air inlet grille 1 can be prevented from interfering with the panel 2 during the opening process, thereby ensuring the smoothness of the opening process of the air inlet grille 1.

[0055] The mounting portion 31 is slidably connected to the air inlet grille 1, and the sliding direction is along the line connecting the first end and the second end (eg Figure 1 in the middle and upper directions).

[0056] The sliding connection has a simple structure and is easy to implement. Moreover, the sliding direction is on the line connecting the first end and the second end, so that when the air inlet grille 1 is opened, the air inlet grille 1 can move relative to the mounting portion 31 in the direction from the first end to the second end, so as to ensure that the air inlet grille 1 does not interfere with the panel 2.

[0057] like Figure 3 As shown, a slide rail is provided on one of the mounting portion 31 and the air inlet grille 1, and a slide groove 12 adapted to the slide rail is provided on the other of the mounting portion 31 and the air inlet grille 1. The slide rail and / or the slide groove 12 extend along the line connecting the first end and the second end, and the slide rail is arranged in the slide groove 12 and can slide relative to the slide groove 12.

[0058] The mounting portion 31 may be provided with a slide rail, and the air inlet grille 1 may be provided with a slide groove 12, or the air inlet grille 1 may be provided with a slide groove 12, and the air inlet grille 1 may be provided with a slide rail. The slide rail is provided in the slide groove 12 and can slide along the extension direction of the slide rail and / or the slide groove 12 to guide the mounting portion 31 to slide relative to the air inlet grille 1 along the connecting direction of the first end and the second end, thereby avoiding jamming or misalignment during the sliding process.

[0059] Optionally, the air inlet grille 1 is provided with a limiting structure, and in the open position, the mounting portion 31 abuts against the limiting structure to limit the extreme position of the mounting portion 31 and prevent the mounting portion 31 from continuing to move toward the closed position relative to the air inlet grille 1.

[0060] Among them, the connecting and matching part 32 is arranged on the air inlet grille 1, and the connecting part 21 cooperates with the connecting and matching part 32 to connect the air inlet grille 1 with the panel 2. When the air inlet grille 1 moves toward the open position, the connecting and matching part 32 moves toward the open position relative to the connecting part 21.

[0061] When the air inlet grille 1 needs to be opened, that is, when the air inlet grille 1 needs to be opened to the open position, the air inlet grille 1 is held by hand to drive the air inlet grille 1 to move toward the open position, and the connecting fitting portion 32 moves toward the open position with the air inlet grille 1 relative to the connecting portion 21. In this way, in addition to the movement of the air inlet grille 1 toward the open position driven by the operator holding the air inlet grille 1 by hand, the air inlet grille 1 can also further move toward the open position due to the movement of the connecting fitting portion 32 toward the open position. In this way, the air inlet grille 1 can avoid interference with the panel 2 during the opening process, thereby ensuring the smoothness of the opening process of the air inlet grille 1.

[0062] The air inlet grille 1 is movably connected to the panel 2, such as a rotating connection or a sliding connection.

[0063] In a specific embodiment, Figure 3 As shown, one of the connecting fitting part 32 and the connecting part 21 includes a rotating shaft 321, and the other of the connecting fitting part 32 and the connecting part 21 includes an axial hole 211. The rotating shaft 321 is arranged in the axial hole 211 and can rotate relative to the axial hole 211 so that the connecting part 21 is rotatably connected to the connecting fitting part 32.

[0064] The rotating shaft 321 is matched with the shaft hole 211 , and the rotation connection between the air inlet grille 1 and the panel 2 is realized through the cooperation between the rotating shaft 321 and the shaft hole 211 .

[0065] The connection matching portion 32 is disposed at the first end portion 13 ; the second end portion 14 is detachably connected to the panel 2 .

[0066] The second end portion 14 and the panel 2 can be connected in various ways such as snap connection, screw connection, or magnetic connection.

[0067] When the air inlet grille 1 needs to be opened, the second end portion 14 is first removed from the panel 2, and the rotating shaft 321 is rotated relative to the shaft hole 211 to rotate the air inlet grille 1 to the open position so as to clean the air inlet grille 1.

[0068] In a specific embodiment, the open position is located below the closed position, so that in the open position, the air inlet grille 1 is at a lower height, which is convenient for the operator to clean. At this time, the connection direction of the closed position and the open position is the up-down direction. Figure 1 As shown, the second end portion 14 of the air inlet grille 1 is rotated downward around the first end portion 13 to reach the open position.

[0069] like Figure 3As shown, the mounting structure 3 further includes a rotating shaft 321 provided on the air inlet grille 1, the rotating shaft 321 is fixedly provided on the mounting portion 31, the mounting structure 3 further includes a first mounting plate 33 and a second mounting plate 34, the first mounting plate 33 and the second mounting plate 34 are connected and a fold is formed at the connection, the rotating shaft 321 is provided on the first mounting plate 33, and the second mounting plate 34 is fixedly provided on the mounting portion 31. For example, the mounting portion 31 is provided with a first buckle 3121 and a second buckle 3122 which are arranged opposite to each other, the first buckle 3121 and the second buckle 3122 enclose an installation space, and the second mounting plate 34 is clamped in the installation space.

[0070] The mounting portion 31 includes a third mounting plate 311 and a fourth mounting plate 312. The fourth mounting plate 312 is connected to the third mounting plate 311 and a folded angle is formed at the connection. The first mounting plate 33 and the second mounting plate 34 are located in the accommodation space surrounded by the third mounting plate 311 and the fourth mounting plate 312. The fourth mounting plate 312 is provided with a through hole 3111. The rotating shaft 321 passes through the accommodation space through the through hole 3111 and then extends into the shaft hole 211. The first buckle 3121 and the second buckle 3122 are provided on the fourth mounting plate.

[0071] The cross section of the rotating shaft 321 is circular or non-circular.

[0072] When the cross section of the rotating shaft 321 is circular, the rotation center of the rotating shaft 321 is fixed during the opening process of the air inlet grille 1, but since the air inlet grille 1 moves toward the open position relative to the mounting portion 31, the total amplitude of the movement of the air inlet grille 1 toward the open position is one of the operator driving the air inlet grille 1 toward the open position, and the other is the movement of the air inlet grille 1 relative to the mounting portion 31 in the direction from the first end to the second end. Therefore, the amplitude of the movement of the air inlet grille 1 toward the open position is large, which can avoid interfering with the panel 2.

[0073] like Figure 5 and Figure 6As shown, the cross section of the rotating shaft 321 may also be non-circular, for example, elliptical. In this way, during the movement of the air inlet grille 1 toward the open position, the rotation center of the rotating shaft 321 moves toward the open position, driving the air inlet grille 1 to further move toward the open position. The total amplitude of the movement of the air inlet grille 1 toward the open position is that the operator drives the air inlet grille 1 to move toward the open position, the air inlet grille 1 moves relative to the mounting portion 31 in the direction from the first end to the second end, and the rotation center of the rotating shaft 321 moves toward the open position. Therefore, the amplitude of the movement of the air inlet grille 1 toward the open position is further increased compared to the amplitude when the cross section of the rotating shaft 321 is circular, ensuring that the air inlet grille 1 does not interfere with the panel 2 during the opening process. In other words, when the connecting and matching portion 32 is the rotating shaft 321 and the connecting portion 21 is the shaft hole 211, during the movement of the air inlet grille 1 toward the open position, the rotation center of the rotating shaft 321 moves toward the open position, so that the air inlet grille 1 also moves toward the open position with the movement of the rotation center of the rotating shaft 321, so as to avoid interference between the air inlet grille 1 and the panel 2.

[0074] When the connecting fitting portion 32 is the shaft hole 211 and the connecting portion 21 is the rotating shaft 321, during the movement of the air inlet grille 1 toward the open position, the rotation center of the shaft hole 211 moves toward the open position, and thus the air inlet grille 1 also moves toward the open position along with the movement of the rotation center of the shaft hole 211, so as to avoid interference between the air inlet grille 1 and the panel 2.

[0075] Optionally, the connecting fitting portion 32 includes a rotating shaft 321, and the connecting portion 21 includes an axial hole 211, wherein the size of the rotating shaft 321 in a preset direction in the closed position is greater than the size of the rotating shaft 321 in the preset direction in the open position, and the preset direction is a line from the closed position to the open position.

[0076] In the closed position, the dimension of the rotating shaft 321 in the preset direction is L1, and in the open position, the dimension of the rotating shaft 321 in the preset direction is L2, and L1 is greater than L2. In this way, when the air inlet grille 1 is opened, the rotating shaft 321 rotates in the shaft hole 211, and the rotation center of the rotating shaft 321 moves toward the open position, and the air inlet grille 1 moves toward the open position as the rotation center of the rotating shaft 321 moves.

[0077] Optionally, the cross section of the rotating shaft 321 is elliptical.

[0078] On the one hand, the elliptical shape can realize smooth rotation of the rotating shaft 321 in the shaft hole 211, avoiding large resistance or even jamming during the rotation of the rotating shaft 321. On the other hand, the elliptical shape can ensure that the size of the rotating shaft 321 in the preset direction in the closed position is larger than the size of the rotating shaft 321 in the preset direction in the open position.

[0079] It can be understood that the cross section of the rotating shaft 321 may not be an ellipse. For example, the cross section of the rotating shaft 321 may be a rectangle with chamfered corners at four corners.

[0080] Optionally, in the closed position, the major axis direction of the ellipse is a preset direction, such as Fig.12 As shown; in the open position, the minor axis direction of the ellipse is the preset direction, such as Figure 6 shown.

[0081] Thus, when the air inlet grille 1 moves toward the open position, the connecting fitting portion 32 moves toward the open position with the maximum amplitude relative to the connecting portion 21, or the rotation center of the rotating shaft 321 moves toward the open position with the maximum amplitude.

[0082] In some embodiments, the connecting mating portion 32 includes an axial hole 211, and the connecting portion 21 includes a rotating shaft 321, wherein the size of the axial hole 211 in a preset direction in the closed position is greater than the size of the axial hole 211 in the preset direction in the open position, and the preset direction is a line connecting the closed position to the open position.

[0083] In the closed position, the size of the shaft hole 211 in the preset direction is L3, and in the open position, the size of the shaft hole 211 in the preset direction is L4, and L3 is greater than L4. In this way, when the air inlet grille 1 is opened, the shaft hole 211 rotates with the air inlet grille 1, and the rotation center of the shaft hole 211 moves toward the open position, and the air inlet grille 1 moves toward the open position with the movement of the rotation center of the shaft hole 211.

[0084] Optionally, the cross section of the shaft hole 211 is elliptical.

[0085] Optionally, the connection fitting portion 32 is movably connected to the air inlet grille 1 and can move relative to the air inlet grille 1 in the direction of a line connecting the closed position and the open position.

[0086] In this way, during the opening process of the air inlet grille 1, the air inlet grille 1 can move relative to the connecting fitting portion 32, and the movement direction is from the closed position toward the open position, so that the air inlet grille 1 moves further toward the open position, thereby better ensuring that the air inlet grille 1 does not interfere with the panel 2 during the opening process.

[0087] Optionally, the connection fitting portion 32 is slidably connected to the air inlet grille 1 .

[0088] Optionally, the housing assembly 100 further includes a support structure 4 , which is disposed on the panel 2 and is used to support the connection mating portion 32 in the open position.

[0089] like Figure 6As shown, during the opening process of the air inlet grille 1, the rotation center of the connecting fitting part 32 moves toward the open position. In order to limit the movement of the rotation center, a support structure 4 is provided to support the connecting fitting part 32 in the open position and limit the connecting fitting part 32 from continuing to move toward the open position, thereby fixing the position of the connecting fitting part 32 and avoiding the instability of the position of the connecting fitting part 32, which causes the air inlet grille 1 to be unable to stabilize in the open position.

[0090] When the connection fitting portion 32 is a rotating shaft 321 and the connection portion 21 is a shaft hole 211, the support structure 4 includes at least a portion of the hole wall of the shaft hole 211. Along the direction from the closed position to the open position, the rotating shaft 321 and the at least a portion of the hole wall of the shaft hole 211 are arranged in sequence. In this way, when the air inlet grille 1 moves toward the open position, the rotation center of the rotating shaft 321 moves toward the open position, so that the rotating shaft 321 abuts against the at least a portion of the hole wall of the shaft hole 211, and the at least a portion of the hole wall of the shaft hole 211 plays a supporting role for the rotating shaft 321, limiting the rotating shaft 321 from continuing to move toward the open position. In the closed position, the support structure is also used to support the connection fitting portion to prevent the connection fitting portion from rotating, thereby stabilizing the air inlet grille in the closed position and preventing the air inlet grille from moving toward the open position.

[0091] In addition to using the hole wall of the shaft hole 211, the support structure 4 can also be provided with a supporting component other than the shaft hole 211 separately, for example, the supporting component is a convex rib, and in the open position, the connecting fitting portion 32 abuts against the convex rib.

[0092] When the connection matching portion 32 is the shaft hole 211 and the connection portion 21 is the rotating shaft 321, the support structure 4 includes at least a portion of the surface of the rotating shaft 321. Along the direction from the closed position to the open position, the shaft hole 211 and the at least a portion of the surface of the rotating shaft 321 are sequentially arranged. In this way, when the air inlet grille 1 moves toward the open position, the rotation center of the shaft hole 211 moves toward the open position, so that the shaft hole 211 abuts against the at least a portion of the surface of the rotating shaft 321, and the at least a portion of the surface of the rotating shaft 321 plays a supporting role for the shaft hole 211, limiting the shaft hole 211 from continuing to move toward the open position.

[0093] There are multiple mounting structures, and the multiple mounting structures are arranged in sequence along the length direction of the first end. Figure 2 As shown, the number of mounting structures is two.
