Description

Technical Field

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

[0002] At present, some air conditioners on the market are equipped with air guide plates with rotating shafts that are spliced ​​together. The splicing of such air guide plates is completed by two plates, and the rotating shaft of the air guide plates is formed by the natural buckling of two half shafts.

[0003] During the operation of the air deflector, the rotating shaft is prone to opening in the locking direction, causing the air deflector to be unable to rotate normally. Summary of the Invention

[0004] The problem solved by the present invention is that the rotating shaft of the air guide plate is easy to open.

[0005] In order to solve the above problems, the present invention provides an air guide plate, which can avoid the opening of the rotating shaft and is convenient for disassembly and assembly.

[0006] An embodiment of the present invention provides an air deflector, comprising an outer guide plate and an inner lining plate, wherein the outer guide plate and the inner lining plate are detachably connected, a first half-shaft is provided on the outer guide plate, and a second half-shaft is provided on the inner lining plate, wherein the first half-shaft and the second half-shaft are aligned and buckled to form a cylindrical rotating shaft;

[0007] One of the first half-shaft and the second half-shaft is provided with a locking block, and the other is provided with a locking groove. The locking groove includes a guide sliding section and a locking section connected at an angle. The locking block is embedded in the locking section. When the locking block slides into the guide sliding section along the locking section, the first half-shaft and the second half-shaft are staggered and engaged. When the locking block moves along the guide sliding section in a direction away from the locking section, the first half-shaft and the second half-shaft are released from the staggered engagement.

[0008] In actual use, when the air deflector needs to be disassembled, the aligned first and second half-axles are pushed in opposite directions in the extension direction, which drives the locking block to slide from the locking section into the guide section. The locking section releases the locking block, and the first and second half-axles are then separated in the extension direction of the guide section. During this process, the locking block can slide out along the guide section. Therefore, the air deflector provided by this embodiment can avoid the need for a rotating shaft opening, and the disassembly process is convenient and quick.

[0009] In an optional embodiment, the two side walls of the locking section are spaced apart in the engagement direction of the first half-shaft and the second half-shaft, and the locking block contacts the side wall of the locking section on a side close to the guide slide section.

[0010] The locking block is embedded in the locking section and is limited by the two side walls of the locking section in the fastening direction to achieve locking, thereby preventing the first half-shaft and the second half-shaft from separating in the fastening direction.

[0011] In an optional embodiment, an extension direction of the guide sliding section is parallel to a fastening direction of the first semi-shaft and the second semi-shaft.

[0012] When joining the wind deflector, align the locking block with the guide section and slide it in until the locking block slides into the locking section, and the first half-shaft and the second half-shaft are staggered and buckled.

[0013] In an optional embodiment, an extension direction of the locking segment is parallel to an extension direction of the cylindrical rotating shaft.

[0014] The extension direction of the locking section is parallel to the extension direction of the cylindrical rotating shaft, which avoids the need for the locking block to slide into the locking section in the state of misaligned fastening, and affects the connection structure between the outer air guide plate and the inner lining plate.

[0015] In an optional embodiment, a guide sliding wall is provided at the connection between the guide sliding section and the locking section, and the guide sliding wall forms an angle with both the guide sliding section and the locking section.

[0016] The guide sliding wall is the chamfer at the corner of the guide sliding section and the locking section. The guide sliding wall prevents the locking block from getting stuck at the corner when sliding from the guide sliding section into the locking section and when sliding from the locking section into the guide sliding section.

[0017] In an optional embodiment, the locking block is convexly provided on the inner wall of the first half-shaft, a slot seat is convexly provided on the second half-shaft, the locking slot is concavely provided on the slot seat, and the slot seat extends into the first half-shaft.

[0018] The locking block is convexly arranged on the inner wall of the first half shaft, and the groove seat extends into the first half shaft to cooperate with the locking block. The cooperating structure is accommodated in the cylindrical rotating shaft, thereby hiding the cooperating structure, improving the aesthetics and preventing interference with the rotation process of the air guide plate.

[0019] In an optional embodiment, there are multiple locking blocks, including a first locking block and a second locking block, and the first locking block and the second locking block are spaced apart in the radial direction of the first half-axis. There are multiple slot seats, including a first slot seat and a second slot seat, and the first locking block cooperates with the first slot seat, and the second locking block cooperates with the second slot seat.

[0020] In an optional embodiment, the side wall of the first groove seat on which the locking groove is recessed and the side wall of the second groove seat on which the locking groove is recessed face away from each other in the radial direction of the second semi-shaft.

[0021] The side walls of the locking grooves of the first slot seat and the second slot seat are respectively arranged to face away from each other in the radial direction of the second half shaft. When the first locking block cooperates with the first slot seat and the second locking block cooperates with the second slot seat, the first slot seat and the second slot seat realize radial limitation of the two locking blocks.

[0022] In an optional embodiment, a snap ring is vertically provided on the outer guide plate, and a buckle is provided on the inner lining plate. The buckle is clamped on the snap ring, and when the locking block slides into the guide sliding section along the locking section, the buckle is disengaged from the snap ring.

[0023] When the locking block slides along the locking section into the guide section, the buckle and the snap ring disengage. As the locking block slides out along the guide section, the outer guide plate and the inner lining plate can be smoothly separated, making disassembly easy and the two parts do not interfere with each other. When the locking block slides along the guide section, the buckle and the snap ring are aligned. When the locking block slides along the locking section away from the guide section, the buckle engages the snap ring, achieving synchronous engagement of the two parts.

[0024] An embodiment of the present invention also provides an air conditioner, comprising the above-mentioned air guide plate, wherein the air guide plate comprises an outer guide plate and an inner lining plate, the outer guide plate and the inner lining plate are detachably connected, a first half-shaft is provided on the outer guide plate, and a second half-shaft is provided on the inner lining plate, the first half-shaft and the second half-shaft are aligned and buckled to form a cylindrical rotating shaft; one of the first half-shaft and the second half-shaft is provided with a locking block, and the other is provided with a locking groove, the locking groove comprises a guide sliding section and a locking section connected at an angle, the locking block is embedded in the locking section, when the locking block slides into the guide sliding section along the locking section, the first half-shaft and the second half-shaft are staggered and buckled, and when the locking block moves along the guide sliding section in a direction away from the locking section, the first half-shaft and the second half-shaft are released from the staggered buckling.

DETAILED DESCRIPTION

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0035] See also Figure 1 , Figure 1 Shown is a cross-sectional view of the air guide plate 100 provided in this embodiment.

[0036] The air deflector 100 provided in this embodiment includes an outer guide plate 110 and an inner lining plate 130. The outer guide plate 110 and the inner lining plate 130 are detachably connected. A first semi-axle 111 is provided on one side of the outer guide plate 110 and is coplanar with the first semi-axle 111. A second semi-axle 131 is provided on one side of the inner lining plate 130 and is coplanar with the inner lining plate 130. The first semi-axle 111 and the second semi-axle 131 are aligned and engaged to form a cylindrical rotating shaft. The air deflector 100 is applied to an air conditioner. In actual use, the cylindrical rotating shaft is connected to the air direction adjustment device of the air conditioner. Driven by the adjustment device, the air deflector 100 rotates to adjust the air outlet direction of the air conditioner.

[0037] It is understood that "locking" refers to the state in which the two opposite side walls of the first semi-shaft 111 and the two opposite side walls of the second semi-shaft 131 are in contact with each other, forming a cylindrical rotating shaft. "Aligned locking" refers to the state in which the ends of the first semi-shaft 111 and the second semi-shaft 131 meet preset dimensional requirements. For example, in this embodiment, the lengths of the first semi-shaft 111 and the second semi-shaft 131 are equal. In the aligned locking state, the ends of the first semi-shaft 111 are flush with the ends of the second semi-shaft 131. "Misaligned locking" refers to the state in which the ends of the first semi-shaft 111 and the second semi-shaft 131 do not meet the preset dimensional requirements. In this embodiment, in the misaligned locking state, the ends of the first semi-shaft 111 are misaligned with the ends of the second semi-shaft 131.

[0038] See also Figure 2 and Figure 3 , Figure 2 FIG. 1 is a schematic diagram of the exploded structure of the air guide plate 100 provided in this embodiment. Figure 3 Shown Figure 2 A magnified schematic diagram of area A in the middle.

[0039] In this embodiment, a locking block 113 is provided on the first half shaft 111, and a locking groove 133 is provided on the second half shaft 131. The locking groove 133 includes a guide sliding section 1331 and a locking section 1333 connected at an angle. The locking block 113 is embedded in the locking section 1333. The side wall of the locking section 1333 serves to limit the locking block 113 in the engagement direction between the first half shaft 111 and the second half shaft 131. The guide sliding section 1331 is used to guide the locking block 113 to slide into the locking section 1333.

[0040] In other embodiments, the positions of the locking block 113 and the locking slot 133 may be swapped, that is, the locking block 113 may be disposed on the second semi-shaft 131 , and the locking slot 133 may be disposed on the first semi-shaft 111 .

[0041] One end of the guide section 1331 is connected to one end of the locking section 1333. An opening is provided at the end of the guide section 1331 away from the locking section 1333, into which the locking block 113 slides. During assembly of the outer guide plate 110 and the inner lining plate 130, the locking block 113 is slid through the opening of the guide section 1331 into the guide section 1331 and then along the guide section 1331 toward the locking section 1333. During this process, the two side walls of the first half-shaft 111 gradually approach the two side walls of the second half-shaft 131.

[0042] When the locking block 113 slides into the locking section 1333 and connects to one end of the guide sliding section 1331, the first half shaft 111 and the second half shaft 131 are staggered and engaged, that is, the two ends of the first half shaft 111 are staggered with the two ends of the second half shaft 131, and the two side walls of the first half shaft 111 are opposite to the two side walls of the second half shaft 131, and are respectively in contact or nearly in contact.

[0043] Afterwards, the outer guide plate 110 and the inner lining plate 130 are pushed in a staggered direction toward the direction in which the two ends of the first half shaft 111 and the second half shaft 131 are flush. During this process, the locking block 113 slides along the locking section 1333 toward the end away from the guide sliding section 1331 until the first half shaft 111 and the second half shaft 131 are aligned and engaged with each other, thus completing the assembly of the outer guide plate 110 and the inner lining plate 130, and the first half shaft 111 and the second half shaft 131 form a cylindrical rotating shaft.

[0044] In this embodiment, the two side walls of the locking segment 1333 are spaced apart in the engagement direction between the first and second half-shafts 111, 131. The locking block 113 contacts the side wall of the locking segment 1333 on the side closest to the guide section 1331. The locking block 113 is restrained by the side walls of the locking segment 1333, thereby ensuring that the distance between the side walls of the first and second half-shafts 111, 131 remains constant in the engagement direction.

[0045] When the air deflector 100 needs to be disassembled into the outer guide plate 110 and the inner lining plate 130, the first half-shaft 111 and the second half-shaft 131 are displaced and pushed, causing the locking block 113 to slide along the locking section 1333 toward the guide slide section 1331. During the sliding process, the first half-shaft 111 and the second half-shaft 131 are always in a displaced and engaged state. By providing a connection structure between the outer guide plate 110 and the inner lining plate 130, when the locking block 113 slides to the end where the locking section 1333 connects to the guide slide section 1331, the outer guide plate 110 and the inner lining plate 130 are disconnected. At this time, the first half-shaft 111 and the second half-shaft 131 are separated in a direction opposite to the engagement direction. During this process, the locking block 113 slides along the guide slide section 1331 in a direction away from the locking section 1333. When the locking block 113 slides into the guide slide section 1331 , the outer guide plate 110 is separated from the inner lining plate 130 , and the disassembly of the air guide plate 100 is completed.

[0046] In this embodiment, to facilitate assembly and disassembly, the extending direction of the guide section 1331 is parallel to the engagement direction of the first half-shaft 111 and the second half-shaft 131. During assembly, as the locking block 113 slides along the guide section 1331 toward the locking section 1333, the first half-shaft 111 and the second half-shaft 131 move toward each other. In other embodiments, the extending direction of the guide section 1331 can also be set to form a certain angle with the engagement direction of the first half-shaft 111 and the second half-shaft 131. In this case, as the locking block 113 slides along the guide section 1331 toward the locking section 1333, the first half-shaft 111 and the second half-shaft 131 move toward each other at an oblique angle.

[0047] In this embodiment, the extension direction of the locking segment 1333 is parallel to the extension direction of the cylindrical shaft, that is, the extension direction of the locking segment 1333 is perpendicular to the extension direction of the guide slide segment 1331. In other embodiments, the extension direction of the locking segment 1333 can also be set to form a certain angle with the extension direction of the cylindrical shaft. In this case, when the locking block 113 slides from the guide slide segment 1331 into one end of the locking segment 1333, the first half-shaft 111 and the second half-shaft 131 do not achieve misaligned engagement. When the locking block 113 slides along the locking segment 1333 away from the guide slide segment 1331 to a certain position, the first half-shaft 111 and the second half-shaft 131 directly achieve aligned engagement.

[0048] See also Figure 4 and Figure 5, Figure 4 FIG. 1 is a schematic structural diagram of the inner lining plate 130. Figure 5 Shown Figure 4 Schematic diagram of the enlarged area B.

[0049] In order to prevent the locking block 113 from getting stuck during the process of sliding from the guide section 1331 into the locking section 1333 or from the locking section 1333 into the guide section 1331, in this embodiment, a guide wall 1332 is provided at the connecting corner between the guide section 1331 and the locking section 1333, and the guide wall 1332 forms an angle with the guide section 1331 and the locking section 1333.

[0050] Considering aesthetics and preventing interference with the rotation of the air deflector 100, in this embodiment, a locking block 113 is protruding from the inner wall of the first half-shaft 111. A recess 135 is protruding from the second half-shaft 131. The locking slot 133 is recessed on one side of the recess 135, which extends into the first half-shaft 111. When the first and second half-shafts 111, 131 are aligned and engaged to form a cylindrical shaft, the recess 135 engages with the locking block 113 within the cylindrical shaft.

[0051] See also Figure 6 and Figure 7 , Figure 6 FIG. 1 is a schematic structural diagram of the outer guide plate 110 at a first viewing angle. Figure 7 FIG. 1 is a schematic structural diagram of the outer guide plate 110 at a second viewing angle.

[0052] In this embodiment, there are multiple locking blocks 113, including a first locking block and a second locking block. The first locking block and the second locking block are spaced apart in the radial direction of the first semi-shaft 111. In practice, the first locking block and the second locking block are respectively disposed on the inner wall of the first semi-shaft 111, near the sidewalls on both sides. The multiple first locking blocks are sequentially spaced apart in the extension direction of the first semi-shaft 111, and the multiple second locking blocks are sequentially spaced apart in the extension direction of the first semi-shaft 111.

[0053] Correspondingly, there are multiple slot seats 135, including a first slot seat and a second slot seat. The first slot seat and the second slot seat are respectively arranged on the inner wall of the second half-shaft 131 near the side walls. The first slot seats are sequentially spaced apart in the extension direction of the second half-shaft 131, and the second slot seats are sequentially spaced apart in the extension direction of the second half-shaft 131. Locking slots 133 are recessed in each of the first and second slot seats. The first locking blocks respectively engage with the locking slots 133 recessed in the first slot seats, and the second locking blocks respectively engage with the locking slots 133 recessed in the second slot seats.

[0054] In addition, the side wall of one side of the recessed locking groove 133 on the first groove seat and the side wall of the recessed locking groove 133 on the second groove seat diverge from each other in the radial direction of the second half shaft 131. In actual application, the first locking block is limited by the bottom wall of the first groove seat, and the second locking block is limited by the bottom wall of the second groove seat, thereby realizing radial limitation of both sides of the first half shaft 111 and preventing the first half shaft 111 from deforming and causing its two sides to shrink inward.

[0055] Please refer to Figure 4 and Figure 7 A snap ring 115 is provided on the outer guide plate 110, and a buckle 137 is provided on the inner lining plate 130. The buckle 137 is clamped on the snap ring 115. When the locking block 113 slides into the guide sliding section 1331 along the locking section 1333, the buckle 137 is disengaged from the snap ring 115.

[0056] During the assembly of the air guide plate 100, the locking block 113 is first slid into the guide section 1331 of the locking groove 133. When the locking block 113 slides into the locking section 1333, the buckle 137 on the inner lining plate 130 is aligned with the snap ring 115 on the outer guide plate 110. Then, the outer guide plate 110 and the inner lining plate 130 are pushed so that the locking block 113 slides along the locking section 1333 in the direction away from the guide section 1331. When the first half shaft 111 and the second half shaft 131 are aligned and engaged, the buckle 137 is just snapped into the snap ring 115, thereby realizing the connection between the outer guide plate 110 and the inner lining plate 130.

[0057] During the process of disassembling the air guide plate 100, the outer guide plate 110 and the inner lining plate 130 are pushed so that the locking block 113 slides along the locking section 1333 toward the guide sliding section 1331. During this process, the buckle 137 gradually withdraws from the snap ring 115. When the locking block 113 slides to the end where the locking section 1333 connects to the guide sliding section 1331, the buckle 137 just completely withdraws from the snap ring 115, and the outer guide plate 110 and the inner lining plate 130 are disconnected. Then, the first half-shaft 111 and the second half-shaft 131 are pried apart in the direction opposite to the fastening direction until the locking block 113 slides out of the guide sliding section 1331, completing the disassembly of the outer guide plate 110 and the inner lining plate 130.

[0058] In summary, the air guide plate 100 provided in this embodiment can avoid the opening of the cylindrical shaft, ensure smooth rotation, and is convenient for disassembly and assembly, so as to facilitate replacement and reuse of components.

[0059] This embodiment also provides an air conditioner, including the aforementioned air guide plate 100. The air guide plate 100 can avoid the cylindrical shaft opening. Therefore, the air conditioner provided by this embodiment has the characteristics of stable and reliable air guiding process, long service life, and repeatable maintenance and utilization.

[0060] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the scope defined by the claims.
