[0045] 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.

[0046] Combination Figure 1-10 As shown, an embodiment of the present disclosure provides a housing assembly for an indoor unit of an air conditioner, including a panel 10, an air inlet grille 20, a lifting rod 30 and a driving member.

[0047] Combination Figure 1 and Figure 6 As shown, the panel 10 is provided with a mounting hole 11; the air inlet grille 20 is provided at the mounting hole 11 and can move relative to the panel 10 between a closed position closing the mounting hole 11 and an open position opening the mounting hole 11; the lifting rod 30 is movably connected to the air inlet grille 20; the driving member is drivingly connected to the lifting rod 30 to drive the air inlet grille 20 to move between the closed position and the open position through the lifting rod 30, wherein the driving member includes a hydraulic cylinder or a pneumatic cylinder.

[0048] The lifting rod 30 moves to the closed position. Figure 1 As shown, the lifting rod 30 moves to the open position as shown in FIG. Figure 6 shown.

[0049] By driving the lifting rod 30 hydraulically by a hydraulic cylinder or by driving the lifting rod 30 pneumatically by a pneumatic cylinder, the stroke can be fixed, making the control of the lifting stroke more precise. At the same time, compared with ordinary motor gear wire rope transmission, the lifting rod 30 can be lifted more smoothly to avoid large shaking.

[0050] By using the housing assembly for the indoor unit of the air conditioner provided by the embodiment of the present disclosure, the driving member drives the lifting rod 30 to drive the air inlet grille 20 to move between the closed position of closing the mounting hole 11 and the open position of opening the mounting hole 11 relative to the panel 10, so that the air inlet grille 20 can be automatically lifted and lowered. The lifting rod 30 is movably connected to the air inlet grille 20, and the air inlet grille 20 can be adjusted in multiple directions, and the ability to adjust the angle of the air inlet grille 20 is enhanced, thereby improving the flexibility of cleaning and maintaining the air inlet grille 20. At the same time, by using a hydraulic cylinder or a pneumatic cylinder as a driving member, a stable and reliable power output can be provided, and the stability and precise control of the movement of the air inlet grille 20 are improved.

[0051] Optionally, combined Figure 7-10 As shown, the lifting rod 30 and the air inlet grille 20 are connected in a rolling manner.

[0052] The rolling connection can reduce the friction between the lifting rod 30 and the air inlet grille 20. When the air inlet grille 20 is adjusted in multiple directions, the air inlet grille 20 can move smoothly in multiple directions relative to the lifting rod 30, thereby improving the flexibility of the movement of the air inlet grille 20. At the same time, the reduction of friction between the lifting rod 30 and the air inlet grille 20 can also reduce noise and improve the durability of the lifting rod 30 and the air inlet grille 20.

[0053] Optionally, combined Figure 2-5 , Figure 8 and Fig.10 As shown, one of the lifting rod 30 and the air inlet grille 20 is provided with a rolling body 31 , and the other of the lifting rod 30 and the air inlet grille 20 is provided with a groove 21 . The rolling body 31 is arranged in the groove 21 and can roll relative to the groove 21 .

[0054] The rolling body 31 rolls in the groove 21, thereby achieving a rolling connection between the lifting rod 30 and the air inlet grille 20. The groove 21 can provide a stable guide for the movement of the rolling body 31, reduce the movement error caused by friction or misalignment, and enhance the structural stability.

[0055] It can be understood that the lifting rod 30 may be provided with a rolling body 31, the air inlet grille 20 may be provided with a groove 21, the rolling body 31 may be provided in the groove 21 and may roll relative to the groove 21; or the air inlet grille 20 may be provided with a rolling body 31, the lifting rod 30 may be provided with a groove 21, the rolling body 31 may be provided in the groove 21 and may roll relative to the groove 21.

[0056] The present application takes an example in which the lifting rod 30 is provided with a rolling body 31 , the air inlet grille 20 is provided with a groove 21 , and the rolling body 31 is arranged in the groove 21 and can roll relative to the groove 21 .

[0057] Optionally, combined Figure 8 and Fig.10As shown, the rolling body 31 is a sphere, which is arranged at the bottom of the lifting rod 30; the groove 21 is a hemispherical groove 21, which is arranged on the side of the air inlet grille 20 facing the lifting rod 30, and the ball is arranged in the hemispherical groove 21 and can roll relative to the hemispherical groove 21.

[0058] A sphere is arranged at the bottom of the lifting rod 30, and a hemispherical groove 21 is correspondingly arranged on the air inlet grille 20. A rolling matching structure is adopted between the sphere and the hemispherical groove 21. The movement friction coefficient of the sphere in the hemispherical groove 21 is low, and the sphere can freely rotate in different directions along the circumference of the hemispherical groove 21 in the hemispherical groove 21, thereby improving the flexibility of angle adjustment.

[0059] Meanwhile, when there are multiple lifting rods 30 , even if the lifting rods 30 are not synchronized during the lifting process, the angle of the air inlet grille 20 can be adjusted by rotating the sphere to avoid damage to the lifting rods 30 or the air inlet grille 20 .

[0060] Optionally, combined Figure 8 and Fig.10 As shown, the center of the rolling body 31 is located in the groove 21 , and the opening 211 of the groove is smaller than the diameter of the rolling body 31 .

[0061] The center of the rolling body 31 is located in the groove 21, and the opening 211 of the groove is smaller than the diameter of the rolling body 31, which can limit the rolling body 31 in the groove 21, improve the stability of the rolling body 31 in the groove 21 and the tightness of the rolling connection, and reduce the probability of the rolling body 31 escaping from the groove 21, thereby improving the connection stability between the lifting rod 30 and the air inlet, and enhancing the safety of the structure.

[0062] Optionally, combined Figure 4 and Figure 8 As shown, a groove wall 212 of the groove 21 is provided with a cutout 213 .

[0063] A notch 213 is provided on the groove wall 212 of the groove 21 to allow the groove 21 to deform to a certain extent during installation, so that the rolling body 31 can be more easily embedded in the groove 21, reducing the difficulty of installation and the possibility of component damage during installation.

[0064] Optionally, combined Figure 5-7 As shown, the lifting rod 30 is a telescopic rod, and the telescopic direction of the telescopic rod is along the line connecting the closed position and the open position.

[0065] The telescopic rod can adjust the length as needed, so that the air inlet grille 20 can be flexibly changed between the closed position and the open position to adapt to different spaces and usage requirements. When the air inlet grille 20 is in the closed position, the telescopic rod can be retracted to the shortest length, saving space and making the housing assembly more compact. When the telescopic rod drives the air inlet grille 20 to move from the closed position to the open position, the telescopic rod can be quickly unfolded, increasing the flexibility of use.

[0066] Optionally, the telescopic rod comprises a plurality of telescopic sections, which are sequentially fitted along the connecting line direction of the closed position and the open position and can slide relatively. The telescopic function of the telescopic rod is achieved by fitting and sliding the plurality of telescopic sections.

[0067] Optionally, the housing assembly for the indoor unit of the air conditioner further includes a flexible member, and the flexible member is connected between the lifting rod 30 and the air inlet grille 20 .

[0068] The lifting rod 30 is movably connected to the air inlet grille 20 through the flexible member. The use of the flexible member enables the air inlet grille 20 to better meet the cleaning and maintenance requirements at different angles. At the same time, the flexible member can provide a buffer between the air inlet grille 20 and the lifting rod 30, reduce the impact and vibration during the movement, and improve stability.

[0069] The flexible member may be a steel wire rope or the like.

[0070] Optionally, combined Figure 1 and Figure 6 As shown, there are multiple lifting rods 30, and the multiple lifting rods 30 are divided into a first group of lifting rods 32 and a second group of lifting rods 33. The air inlet grille 20 includes a first end 22 and a second end 23. The first group of lifting rods 32 is arranged at the first end 22; the second end 23 is arranged opposite to the first end 22, and the second group of lifting rods 33 is arranged at the second end 23.

[0071] The arrangement of multiple lifting rods 30 allows independent control of different parts of the air inlet grille 20, which can improve the accuracy and flexibility of adjustment. Multiple lifting rods 30 can also provide better support and enhance the strength and rigidity of the air inlet grille 20 structure.

[0072] By dividing the lifting rods 30 into two groups, with the first group of lifting rods 32 and the second group of lifting rods 33 respectively arranged at the first end 22 and the second end 23 opposite to the air inlet grille 20, the opening angle and position of the air inlet grille 20 can be more finely controlled, thereby improving the balance and accuracy of the movement of the air inlet grille 20.

[0073] Optionally, combined Figure 1 and Figure 6 As shown, the first group of lifting rods 32 and the second group of lifting rods 33 are staggered.

[0074] The staggered arrangement of the first group of lifting rods 32 and the second group of lifting rods 33 can provide better force distribution and reduce the load of the single group of lifting rods 30, thereby improving the stability and durability of the entire housing assembly.

[0075] Optionally, combined Figure 1 and Figure 6 As shown, there are multiple lifting rods 30 in the first group of lifting rods 32, and the multiple lifting rods 30 in the first group of lifting rods 32 are arranged in sequence along the length direction of the first end 22, and there is only one lifting rod 30 in the second group of lifting rods 33.

[0076] The plurality of lifting rods 30 in the first group of lifting rods 32 are sequentially arranged along the length direction of the first end portion 22, and the opening and closing angle and position of the air inlet grille 20 can be more finely adjusted at the first end portion 22. The number of the lifting rod 30 in the second group of lifting rods 33 is one, and a stable support can be provided at the second end portion 23 of the air inlet grille 20.

[0077] Optionally, combined Figure 1 and Figure 6 As shown, there are two lifting rods 30 in the first group of lifting rods 32 , and the two lifting rods 30 are respectively located at the two ends of the first end 22 in the length direction, and the second group of lifting rods 33 is arranged in the middle of the second end 23 in the length direction.

[0078] There are three lifting rods 30, wherein two lifting rods 30 in the first group of lifting rods 32 are respectively located at the two ends of the length direction of the first end portion 22, and one lifting rod 30 in the second group of lifting rods 33 is located in the middle of the length direction of the second end portion 23, so that the three lifting rods 30 are distributed in a triangular shape on the air inlet grille 20, which can improve the consistency of the lifting of the lifting rods 30 and enable the air inlet grille 20 to maintain a stable rise and fall.

[0079] Optionally, combined Figure 1 As shown, the housing assembly for the indoor unit of the air conditioner also includes a detection element 40 and a controller. The detection element 40 is arranged on the air inlet grille 20 and / or the panel 10, and is used to detect the position of the air inlet grille 20 relative to the panel 10; the controller is connected to both the detection element 40 and the driving member, and is used to control the driving member to drive the lifting rod 30 to drive the air inlet grille 20 to move to the preset position when the detection element 40 detects that the air inlet grille 20 is not in the preset position; wherein the preset position is an open position or a closed position.

[0080] The detection element 40 can be a position sensor such as a micro switch. The position of the air inlet grille 20 relative to the panel 10 is detected by the detection element 40, and the detection information is transmitted to the controller. The controller controls the driving member to drive the lifting rod 30 to drive the air inlet grille 20 to move according to the position information of the air inlet grille 20. When the air inlet grille 20 needs to be operated to be lowered, the controller controls the driving member to drive the lifting rod 30 to drive the air inlet grille 20 to move to the open position. When the air inlet grille 20 needs to be operated to be raised, the controller controls the driving member to drive the lifting rod 30 to drive the air inlet grille 20 to move to the closed position. The setting of the detection element 40 can play a fault-tolerant role.

[0081] Optionally, combined Figure 1 As shown, the detection element 40 is disposed adjacent to the lifting rod 30 .

[0082] The detection element 40 is disposed adjacent to the lifting rod 30, and the detection element 40 can more accurately detect the position of the air inlet grille 20. The detection element 40 is disposed next to the lifting rod 30 to detect whether the air inlet grille 20 moves to a preset position. When it is detected that the lifting rod 30 does not move to the preset position, the controller controls the driving member to drive the lifting rod 30 to continue to work to the preset position.

[0083] Optionally, there are multiple detection elements 40 , and the multiple detection elements 40 correspond one-to-one to the multiple lifting rods 30 .

[0084] The plurality of detection elements 40 independently detect the position information of the plurality of lifting rods 30 , respectively, so that the position of the air inlet grille 20 can be controlled more accurately.

[0085] It can be understood that by driving the lifting rod 30 hydraulically or by driving the lifting rod 30 pneumatically, the stroke can be fixed, making the control of the lifting stroke more precise. When the driving member adopts a hydraulic cylinder or a pneumatic cylinder, there is no need to set up a micro switch for position determination, which can save components.

[0086] Optionally, the housing assembly for the indoor unit of the air conditioner also includes a self-locking device, the air inlet grille 20 includes a grille body and a locking fitting portion provided on the grille body; the self-locking device includes a locking portion, the locking portion is provided on the panel 10 and can move relative to the panel 10 between a locking position that cooperates with the locking fitting portion and an unlocking position that is separated from the locking fitting portion; wherein, in the locked position, the force applied by the locking portion to the locking fitting portion has at least a component force from the open position toward the closed position.

[0087] The air inlet grille 20 can be stably locked in the closed position by the self-locking device. In the locked position, the force applied by the locking portion to the locking mating portion has at least a force component from the open position toward the closed position, so that the self-locking device can apply a force to the air inlet grille 20 from the open position toward the closed position, and bear the gravity of the air inlet grille 20.

[0088] Among them, in the locked position, the force applied by the locking part to the locking matching part may have a component force from the open position to the closed position, or the force applied by the entire locking part to the locking matching part may be applied from the open position to the closed position. When the force applied by the entire locking part to the locking matching part is applied from the open position to the closed position, the lifting motor can be in a state of being completely free of force, which can more effectively enhance the reliability of the self-locking device.

[0089] Optionally, the self-locking device further comprises a driving assembly, which is drivingly connected to the locking portion and is used to drive the locking portion to move between a locking position and an unlocking position.

[0090] By driving the locking portion to move between the locking position and the unlocking position through the driving assembly, the operating accuracy and response speed of the self-locking device can be improved, and the reliability of the self-locking device can be improved.

[0091] Optionally, the drive assembly comprises a stepper motor.

[0092] By using a stepper motor to drive the locking part to move between the locked position and the unlocked position, a fixed number of steps can be preset to accurately control the moving position of the locking part. By using a stepper motor to drive the locking part to move between the locked position and the unlocked position, a precise driving force can be provided for the locking part, thereby improving the stability of locking and unlocking.

[0093] Optionally, the controller is connected to both the detection element 40 and the drive assembly, and is used to control the drive assembly to drive the locking portion to move toward the locking position when the detection element 40 detects that the air inlet grille 20 is in the closed position.

[0094] When the detection element 40 detects that the air inlet grille 20 is in the closed position, the controller controls the driving assembly to drive the locking part to move toward the locking position, locking the air inlet grille 20 and the panel 10. Through the cooperation of the detection element 40 and the controller, the position of the air inlet grille 20 is monitored and controlled in real time, which improves the intelligence level of the self-locking device and ensures the safety of operation.

[0095] Optionally, the number of the self-locking devices is equal to the number of the lifting rods 30 and corresponds one to one.

[0096] The number of the lifting rods 30 is equal to and corresponds to the number of the self-locking devices, which can improve the self-locking effect of the air inlet grille 20 .
