Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to an air guide door assembly and an air conditioner. Background Art

[0002] Existing wall mounted air conditioners all have an air guide door that is rotatably connected to the middle frame assembly to open or close the air outlet and to guide the air flow. However, the connection method of the existing air guide door makes it inconvenient to assemble and disassemble. Summary of the Invention

[0003] The problem that the present application solves is that the existing air guide door assembly is not convenient to assemble and disassemble.

[0004] To solve the above problems, in a first aspect, the present application provides an air guide door assembly for use in an air conditioner, comprising a door panel, a rotating shaft cylinder, and a connecting pin, wherein the rotating shaft cylinder is disposed on the door panel, and the connecting pin comprises a clamping member and a connecting shaft, wherein the clamping member is disposed within the rotating shaft cylinder, one end of the connecting shaft is connected to the clamping member, and a portion of the connecting shaft extends from an axially upward end of the rotating shaft cylinder for rotationally connecting to a middle frame assembly of the air conditioner;

[0005] The clamping piece is clamped and matched with the rotating shaft tube. The clamping piece can be deformed by external force to release the match with the rotating shaft tube. A window is opened on the side wall of the rotating shaft tube, and a part of the clamping piece is exposed from the window.

[0006] In an embodiment of the present application, applying external force to the clamping part can release the clamping fit with the rotating shaft tube. The window provided on the rotating shaft tube exposes a portion of the clamping part, making it easy for the user to apply external force to the clamping part to release the clamping fit with the rotating shaft tube without opening the rotating shaft tube. Thereafter, the connecting pin can be moved, and the connecting shaft of the connecting pin can be pulled out from the middle frame assembly of the air conditioner, and then the air guide door assembly can be removed from the middle frame assembly of the air conditioner. Conversely, when installing the air guide door assembly, the connecting pin is slid until the connecting shaft engages with the middle frame assembly, while the clamping part engages with the rotating shaft tube to secure the connecting pin and complete the installation. It can be seen that the air guide door assembly of the embodiment of the present application can achieve high loading and unloading efficiency.

[0007] In an optional embodiment, the clamping member includes a connecting seat and an elastic portion, the elastic portion and the connecting shaft are both connected to the connecting seat, the elastic portion is clamped into engagement with the rotating shaft tube, a portion of the elastic portion is exposed from the window, and the elastic portion can be deformed by external force to thereby release engagement with the rotating shaft tube.

[0008] In an alternative embodiment, the elastic portion includes an elastic arm, one end of which is connected to the edge of the connecting seat and the other end of which extends along the axis of the rotating shaft. The elastic arm is in contact with the inner wall of the rotating shaft and can deform radially relative to the rotating shaft. The elastic arm and the inner wall of the rotating shaft are engaged by a snap-fit ​​structure. In this embodiment, radially pressing the elastic arm bends and deforms the elastic arm, disengaging it from the inner wall of the rotating shaft, thereby releasing the engagement. This structure is simple, effective, and has good stability.

[0009] In an optional embodiment, the snap-fit ​​structure includes a boss provided on the spring arm and a slot provided on the inner wall of the rotating shaft tube. The boss fits into the slot to achieve a snap-fit ​​connection. The combination of the boss and the slot effectively restricts axial movement of the connecting pin. When the spring arm is depressed and deformed, the boss and the slot are effectively released. Therefore, this snap-fit ​​structure effectively switches the connecting pin between the engaged and disengaged states with the rotating shaft tube.

[0010] In an optional embodiment, the latching structure includes at least one pair of latching slots, with the two latching slots in the same pair spaced apart along the axis of the rotating shaft. In this embodiment, the two latching slots in the same pair can be considered as two gear positions. When one of the latching slots engages with the boss, the connecting shaft extends sufficiently beyond the rotating shaft to engage with the middle frame assembly, enabling the air guide door assembly to be installed on the middle frame assembly. When the other latching slot engages with the boss, the connecting shaft retracts partially or completely, disconnecting the air guide door assembly from the middle frame assembly and allowing it to be removed from the middle frame assembly. Providing two latching slots makes it easier for the user to determine whether the connecting pin has moved into position by the feel of a click.

[0011] In an optional embodiment, the inner wall of the rotating shaft cylinder is further provided with a transition groove, which is disposed between two retaining grooves in the same pair and extends in the axial direction of the rotating shaft cylinder. In this embodiment, when the boss moves between the two retaining grooves, it can slide in the transition groove. In this case, there is no need to apply a large external force to radially press the elastic arm, and the boss will not continuously abut the inner wall of the rotating shaft cylinder, thereby preventing the connecting pin from sliding smoothly. Therefore, the user can more easily slide the connecting pin in the axial direction of the rotating shaft cylinder.

[0012] In an optional embodiment, the elastic portion further includes a button protruding from the elastic arm, and the button extends from the window to the outer surface of the shaft tube. In this embodiment, the button is provided on the elastic portion and protrudes from the outer surface of the shaft tube, which can facilitate the user to press the elastic portion to cause deformation.

[0013] In an optional embodiment, the window is a strip-shaped hole and extends along the axial direction of the rotating shaft tube. The window is set as a strip-shaped hole to facilitate the user to directly drag the connecting pin while pressing the elastic part.

[0014] In an alternative embodiment, the shaft cylinder includes a body and a cover. The body is mounted on the door panel and has a radial opening. The cover is removably connected to the opening of the body to enclose the body and form a cavity of the shaft cylinder. In this embodiment, the shaft cylinder is configured to be removable to facilitate assembly of the connecting pin and to facilitate maintenance and replacement of the connecting pin.

[0015] In an optional embodiment, a window is opened in the cover.

[0016] In an optional embodiment, the air guide door assembly includes a plurality of connecting pins, which are spaced apart along the axial direction of the rotating shaft. The air guide door assembly is connected to the middle frame assembly via the plurality of connecting pins, which can improve the stability of the air guide door assembly.

[0017] In a second aspect, the present application provides an air conditioner, comprising a middle frame assembly and an air guide door assembly according to any one of the aforementioned embodiments, wherein the air guide door assembly is rotatably connected to the middle frame assembly via a connecting shaft of a connecting pin.

DETAILED DESCRIPTION

[0026] Currently, wall-mounted air conditioners are often equipped with an air guide door to open or close the air outlet. The air guide door assembly is connected to the middle frame assembly and can rotate relative to the middle frame assembly. Some air guide doors are directly hinged to the middle frame via a high-strength rotating shaft, while others use a transition component to connect the air guide door and the middle frame assembly. With these connection methods, removing the air guide door assembly from the middle frame assembly often requires disassembling the middle frame assembly or the air guide door assembly. Installing the air guide door assembly also requires assembling the parts of the air guide door assembly or the middle frame assembly. Therefore, existing air guide door assemblies are inconvenient to install and remove.

[0027] To address the inconvenience of installing and removing the air guide door assembly in the aforementioned related art, the present invention provides an air guide door assembly and an air conditioner equipped with the air guide door assembly. The air guide door assembly includes a connecting pin that can be slid by an external force. The sliding connecting pin can be engaged or disengaged with the middle frame assembly of the air conditioner, thereby enabling quick installation and removal of the air guide door assembly.

[0028] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0029] Figure 1 This is a schematic diagram of the assembly of the air guide door assembly 010 in one embodiment of the present application; Figure 2 This is an exploded view of the air guide door assembly 010 in one embodiment of the present application; Figure 3 for Figure 1 The enlarged view of the part III in the figure. Figures 1 to 3 As shown, the air guide door assembly 010 provided in the embodiment of the present application includes a door panel 200, a rotating shaft cylinder 100, and a connecting pin 300. The rotating shaft cylinder 100 is disposed on the door panel 200. The connecting pin 300 includes a clamping member 310 and a connecting shaft 320. The clamping member 310 is disposed within the rotating shaft cylinder 100. One end of the connecting shaft 320 is connected to the clamping member 310. A portion of the connecting shaft 320 extends from one axial end of the rotating shaft cylinder 100 for rotational connection with the middle frame assembly (not shown) of the air conditioner. In this embodiment, the door panel 200 is in the shape of an elongated plate, and the rotating shaft cylinder 100 is disposed on the edge of one side of the door panel 200 in the width direction.

[0030] Optionally, the air guide door assembly 010 includes a plurality of connecting pins 300, which are arranged at intervals along the axial direction of the rotating shaft tube 100. The air guide door assembly 010 is connected to the middle frame assembly through the plurality of connecting pins 300, which can improve the stability of the air guide door assembly 010. In this embodiment, two sections of rotating shaft tubes 100 are provided on the door panel 200, with a total of three connecting pins 300. The three connecting pins 300 are located at both ends and the middle of the door panel 200 in the length direction. Among them, the clamping parts 310 of the two connecting pins 300 are provided on the same section of the rotating shaft tube 100 ( Figure 1 The right section) is located at both ends of the shaft tube 100, and the other connecting pin 300 is located at the other section of the shaft tube 100 ( Figure 1 Furthermore, in this embodiment, two buttons 210 are provided at both ends of the door panel 200. The two buttons 210 are detachably connected to the door panel 200. The connecting shafts 320 of the two connecting pins 300 at both ends of the door panel 200 extend from the rotating shaft cylinder 100 and are then inserted into the buttons 210, thereby improving the stability of the connecting pins 300. Figure 4 for Figure 2 The enlarged view of the local IV in the middle is as follows: Figure 4 As shown, the two buttons 210 are inserted into the housings 211 at both ends of the door panel 200 by plugging and are detachably connected to the housings 211 by snapping. The connecting shaft 320 of the middle connecting pin 300 extends out of the rotating shaft tube 100 and can be inserted into the end plate 111 of the adjacent rotating shaft tube 100, which can also improve stability.

[0031] In this embodiment, the end plate 111 of the rotating shaft tube 100 has a through-hole through which the connecting shaft 320 extends, which also serves to radially limit the connecting shaft 320. A gap is formed between the button 210 and the end plate 111 of the rotating shaft tube 100. The connecting shaft 320 exposed in this gap can be rotatably connected to the middle frame assembly. In this embodiment of the present application, the connecting shaft 320 of the connecting pin 300 located in the middle is also exposed by the gap between the end plates 111 of the two adjacent rotating shaft tubes 100, thereby also being rotatably connected to the middle frame assembly.

[0032] In the embodiment of the present application, the clip 310 of the connecting pin 300 can be engaged with the rotating shaft tube 100, thereby fixing the connecting pin 300 relative to the rotating shaft tube 100. In this state, the connecting shaft 320 protrudes from the rotating shaft tube 100, thereby being able to engage with the middle frame assembly. The clip 310 can be deformed by external force, thereby being disengaged from the rotating shaft tube 100. In the embodiment of the present application, a window 121 is provided on the rotating shaft tube 100, exposing a portion of the clip 310, and the user can apply force to the clip 310 through the window 121 to deform it, thereby disengaging it from the rotating shaft tube 100. After disengagement, the connecting pin 300 can be axially slid so that the connecting shaft 320 is withdrawn from the middle frame assembly, thereby achieving the removal of the air guide door assembly 010 from the middle frame assembly. As can be seen, when disassembling the air guide door assembly 010 provided in the embodiment of the present application, there is no need to remove the air guide door assembly 010 or any components on the middle frame assembly. Instead, the air guide door assembly 010 can be removed efficiently by simply applying force to the clip 310 through the window 121 and sliding the connecting pin 300. Similarly, installing the air guide door assembly 010 simply requires moving the air guide door assembly 010 to a position that mates with the middle frame assembly, then pushing the connecting pin 300 to insert the connecting shaft 320 into the hole in the middle frame assembly. Furthermore, in this embodiment, a drive shaft 220 is also provided on the door panel 200. The drive shaft 220 can be transmission-connected to the air conditioner's drive assembly, allowing the drive assembly to drive the door panel 200 to rotate about the connecting shaft 320.

[0033] like Figure 2 As shown, the shaft cylinder 100 of this embodiment includes a cylinder body 110 and a cover body 120. The cylinder body 110 is fixedly arranged on the door panel 200. The cylinder body 110 has a radial opening. The cover body 120 is detachably connected to the opening of the cylinder body 110 to enclose the cylinder body 110 to form a cavity of the shaft cylinder 100. In this embodiment, the shaft cylinder 100 is configured to be detachable, which is convenient for assembling the connecting pin 300 and also convenient for maintenance and replacement of the connecting pin 300. Specifically, one side of the cylinder body 110 is opened to form an opening, and the length of the opening is equivalent to the length of the cylinder body 110, and the cover body 120 is in the shape of an arc plate, which is also equivalent to the length of the cylinder body 110. As shown Figure 4 As shown, the inner side of the opening edge of the cylinder 110 is provided with a buckle portion 112 for engaging with the buckle groove 125 (see FIG. Figure 6 ) to achieve the installation and fixation of the cover body 120.

[0034] Figure 5 This is a schematic diagram of the inner side of the cover 120 in one embodiment of the present application; Figure 6 for Figure 5 An enlarged view of a local VI. Figure 5 and Figure 6As shown, a window 121 is provided in the cover 120. Furthermore, the window 121 is a strip-shaped hole extending axially along the shaft cylinder 100. This strip-shaped hole facilitates the user to directly drag the connecting pin 300 while pressing the elastic portion. In this embodiment, the window 121 is a waist-shaped hole with curved contours at both ends.

[0035] In this embodiment, the clamping member 310 of the connecting pin 300 is clamped with the rotating shaft tube 100 through a clamping structure. The clamping structure includes a boss 313 provided on the clamping member 310 and a clamping groove 122 provided on the inner wall of the rotating shaft tube 100. The boss 313 can be embedded in the clamping groove 122 to achieve a clamping fit. The matching form of the boss 313 and the clamping groove 122 can effectively limit the axial movement of the connecting pin 300, and when the connecting pin 300 is deformed, the boss 313 can be effectively disengaged from the clamping groove 122. Therefore, this clamping structure can better realize the switching between the two states of matching / disengaging the connecting pin 300 and the rotating shaft tube 100. As shown in FIG. Figure 5 and Figure 6 As shown, the slots 122 are disposed on the inner side of the cover 120, specifically on one or both sides of the window 121 in the width direction. In this embodiment, the cover 120 is provided with at least one pair of slots 122. The two slots 122 in the same pair are disposed on the same side of the window 121, and the two slots 122 in the same pair are spaced apart in the axial direction of the rotating shaft cylinder 100. In this embodiment, the two slots 122 in the same pair can be considered as two gear positions. When one slot 122 engages with the boss 313, the connecting shaft 320 extends sufficiently beyond the rotating shaft cylinder 100 to engage with the middle frame assembly, enabling the air guide door assembly 010 to be installed thereon. When the other slot 122 engages with the boss 313, the connecting shaft 320 partially or completely retracts, disconnecting the air guide door assembly 010 from the middle frame assembly and allowing it to be removed from the middle frame assembly. The provision of two slots 122 makes it easier for the user to determine whether the connecting pin 300 has been moved into position by a feel of a click.

[0036] Optionally, two pairs of slots 122 may be provided on the cover 120 , and the two pairs of slots 122 are respectively located on both sides of the window 121 in the width direction.

[0037] like Figure 6As shown in , the inner wall of the rotating shaft cylinder 100 (specifically, the cover body 120) is further provided with a transition groove 123. The transition groove 123 is provided between the two clamping grooves 122 in the same pair and extends in the axial direction of the rotating shaft cylinder 100. In this embodiment, when the boss 313 moves between the two clamping grooves 122, it can slide in the transition groove 123. At this time, it is not necessary to use a large external force to radially press the clamping member 310. The boss 313 will not continuously abut the inner wall of the rotating shaft cylinder 100, causing the connecting pin 300 to slide smoothly, making it easier for the user to slide the connecting pin 300 in the axial direction of the rotating shaft cylinder 100. In other words, the transition groove 123 plays a role of giving way, preventing the boss 313 from abutting against the inner wall due to elastic force, causing large friction resistance.

[0038] It can be understood that in other optional embodiments of the present application, the card slots 122 may not be set in pairs, but only one may be set; the transition groove 123 may also be omitted. As long as the user continues to press down to keep the card connector 310 deformed and slides the connecting pin 300 at the same time, the connecting pin 300 can also be moved in the rotating shaft tube 100.

[0039] In this embodiment, the outer edge of the cover 120 is further provided with a snap-fit ​​groove 125 for engaging with the snap-fit ​​portion 112 on the barrel 110 to secure the cover 120. When the cover 120 needs to be removed, the cover 120 is squeezed from both sides to cause an appropriate amount of deformation, thereby releasing the snap-fit ​​groove 125 from the snap-fit ​​portion 112.

[0040] In this embodiment, a limiting portion 124 is further provided on the inner side of the cover 120 . After the cover 120 is installed in place, the limiting portion 124 is used to abut the end of the connecting pin 300 to limit the connecting pin 300 from excessively retracting into the shaft tube 100 .

[0041] The connecting pin 300 provided in the embodiment of the present application is described in detail below.

[0042] Figure 7 Schematic diagram of a connecting pin 300 in one embodiment of the present application. Figure 7 As shown, the connecting pin 300 provided in the embodiment of the present application includes a clamping member 310 and a connecting shaft 320 connected to the clamping member 310. The clamping member 310 includes a connecting seat 311 and an elastic portion, and the elastic portion and the connecting shaft 320 are both connected to the connecting seat 311. The connecting seat 311 is equivalent to the main body of the clamping member 310, and plays a supporting role for the connecting shaft 320 and the elastic portion. In this embodiment, one side of the connecting seat 311 abuts against the inner wall of the cylinder body 110 of the rotating shaft cylinder 100, and the other side is provided with an elastic portion, which abuts against the inner wall of the cover body 120 of the rotating shaft cylinder 100 and can be engaged with the inner wall of the cover body 120.

[0043] In this embodiment, the elastic portion includes an elastic arm 312, one end of which is connected to the connecting seat 311, and the other end extends along the axis of the rotating shaft tube 100. The elastic arm 312 is attached to the inner wall of the rotating shaft tube 100 (specifically, the inner wall of the cover body 120) and can be deformed in the radial direction of the rotating shaft tube 100. The boss 313 in the snap-fit ​​structure is provided on the elastic arm 312, and the boss 313 can be embedded in the snap-fitting groove 122 provided on the inner wall of the cover body 120 to achieve snap-fitting. A portion of the elastic arm 312 is exposed from the window 121. In this embodiment, by radially pressing the elastic arm 312 through the window 121, the elastic arm 312 can be bent and deformed, so that it disengages from the inner wall of the rotating shaft tube 100, thereby releasing the fit. This structure is simple, effective, and has good stability.

[0044] In an optional embodiment, the elastic portion further includes a button 314 protruding from the elastic arm 312. The button 314 extends from the window 121 to the outer surface of the rotating shaft cylinder 100. In this embodiment, the button 314 is provided on the elastic portion and protrudes from the outer surface of the rotating shaft cylinder 100, making it easier for the user to press the elastic portion to deform it. The button 314 is configured as a circular button 314, with a width slightly smaller than the width of the window 121. In this embodiment, the boss 313 is adjacent to the button 314. When the button 314 slides in the window 121, the boss 313 can engage with or move out of the slot 122 adjacent to the window 121 of the cover 120. As can be seen, the air guide door assembly 010 provided in this embodiment of the application utilizes a deformable connecting pin 300 and provides the window 121 in the rotating shaft cylinder 100. This allows the user to install and remove the air guide door assembly 010 by moving the connecting pin 300 without disassembling the rotating shaft cylinder 100 or the air conditioner's middle frame assembly.

[0045] In this embodiment, the elastic portion is deformed by the bending of the elastic arm 312, so that the clamping member 310 can selectively engage or disengage with the rotating shaft tube 100. In other optional embodiments, the elastic portion can also be deformed by a spring: for example, a movable plate is provided on the connecting seat 311, the plate is connected to the connecting seat 311 by a spring, the plate is engaged with the cover 120, and a portion is exposed from the window 121. The plate can be pressed away from the window 121 by an external force, and the plate can also abut against the inner wall of the cover 120 under the thrust of the spring to achieve a clamping fit. This structure can also achieve switching between engagement / disengagement between the clamping member 310 and the rotating shaft tube 100.

[0046] In summary, the air guide door assembly 010 provided in the embodiment of the present application includes a door panel 200, a rotating shaft cylinder 100, and a connecting pin 300 disposed on the rotating shaft cylinder 100. The connecting pin 300's clip 310 is located within the rotating shaft cylinder 100, and its connecting shaft 320 extends outside the rotating shaft cylinder 100 for rotational connection with the air conditioner's middle frame assembly. Because the clip 310 is deformable, applying an external force to the clip 310 can cause it to deform and release its engagement with the rotating shaft cylinder 100. The window 121 provided in the rotating shaft cylinder 100 exposes a portion of the clip 310, making it easier for the user to apply external force to release the clip 310 from the rotating shaft cylinder 100 without opening the rotating shaft cylinder 100. The connecting pin 300 can then be moved, and its connecting shaft 320 can be removed from the air conditioner's middle frame assembly, allowing the air guide door assembly 010 to be removed from the air conditioner's middle frame assembly. Conversely, when installing the air guide door assembly 010, the connecting pin 300 is slid onto the connecting shaft 320 to engage with the middle frame assembly, while the clamping member 310 is simultaneously engaged with the rotating shaft tube 100 to secure the connecting pin 300 and complete the installation. It can be seen that the air guide door assembly 010 of the present embodiment can achieve high assembly and disassembly efficiency.

[0047] The air conditioner provided in the embodiment of the present application includes the air guide door assembly 010 provided in the embodiment of the present application, and therefore also has the characteristic of easy assembly and disassembly of the air guide door assembly 010.

[0048] Although the present application is disclosed as above, the present application is not limited thereto. Any person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present application. Therefore, the scope of protection of the present application shall be based on the scope defined by the claims.
