Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to an air guide component, an indoor unit, and an air conditioner. Background Technology

[0002] Currently, in addition to the air deflector for vertical airflow guidance, indoor air conditioners also have multiple air guide blades for horizontal airflow guidance. These multiple air guide blades are connected to a connecting rod, which, driven by the connecting rod, guides the airflow at the indoor unit's air outlet horizontally.

[0003] However, in the existing technology, the connecting rod and the guide vane usually adopt a rigid fit structure. The connecting shaft of the guide vane is directly inserted into the fitting hole of the connecting rod. In order to prevent the blade from loosening during the transmission process or due to external loads (such as vibration and impact), the fitting clearance is usually designed to be extremely small, which makes the assembly and disassembly operations extremely difficult. Utility Model Content

[0004] The main objective of this utility model embodiment is to provide an air guide assembly for an electrical control box installation structure, an indoor unit, and an air conditioner, aiming to improve the technical problem of inconvenient disassembly of the air guide blades and connecting rods in the prior art.

[0005] An embodiment of this utility model provides an air guide assembly, comprising:

[0006] A connecting rod, wherein a fixing hole and an elastic claw are provided on the connecting rod, the fixing hole extends through the connecting rod along the thickness direction, and one end of the elastic claw is connected to the connecting rod and located at the edge of the fixing hole;

[0007] The air guide vane has a connecting shaft at one end, which is inserted into the fixing hole, and the end of the connecting shaft away from the air guide vane is connected to the elastic claw.

[0008] The free end of the elastic claw is configured to be able to shift from a first position to a second position under the action of an external force and return to the first position after the external force is removed. When the free end is in the first position, the connecting shaft is locked to the elastic claw so that the connecting shaft is locked to the fixing hole.

[0009] When the free end is in the second position, the connecting shaft separates from the elastic claw, so that the connecting shaft can be pulled out of the fixing hole.

[0010] In some embodiments of this utility model, the connecting shaft includes a shaft body and a limiting part, wherein the limiting part is disposed at the end of the shaft body away from the guide vane;

[0011] When the free end is in the first position, the orthographic projection of the free end on the fixing hole is close to the center of the fixing hole, so that when the free end is in the first position, it abuts against the end of the limiting part near the shaft, and restricts the limiting part to the other side of the connecting rod.

[0012] When the free end is in the second position, the orthographic projection of the free end onto the fixing hole is outside the fixing hole, so that the free end is away from the limiting part when it is in the second position.

[0013] In some embodiments of this utility model, the limiting part is configured to deform under the action of external force, changing from a first form to a second form, and returning to the first form after the external force is removed;

[0014] When the limiting part is in the first form, the width of the limiting part is greater than the width of the fixing hole;

[0015] When the limiting part is in the second form, the width of the limiting part is smaller than the width of the fixing hole.

[0016] In some embodiments of this utility model, a deformation groove is provided on the connecting shaft. The deformation groove extends from the end of the limiting part away from the shaft body along the length direction of the connecting shaft to the shaft body, so that the limiting part can be transformed from the first form to the second form under the action of external force, and return to the first form after the external force is removed.

[0017] In some embodiments of this utility model, the width of the shaft gradually increases from one end near the limiting part to the other end near the guide vane until it is the same as the width of the fixing hole.

[0018] In some embodiments of this utility model, the shaft includes a connecting part and a main body. The connecting part is connected between the main body and the guide vane. The other end of the main body is connected to the limiting part. The width of the connecting part is greater than the width of the main body to form a stepped structure.

[0019] The fixing hole is a stepped shaft hole that mates with the shaft body.

[0020] In some embodiments of this utility model, the elastic claw is a sheet-like structure, and the thickness of the elastic claw gradually increases from the free end to the end near the connecting rod.

[0021] In some embodiments of this utility model, the elastic claw includes at least a plurality of sub-claws, which are distributed along the circumferential direction of the fixing hole and spaced apart from each other. The sub-claws are configured to be offset from a first position to a second position under the action of an external force and to return to the first position after the external force is removed.

[0022] When the sub-claw is in the first position, it is locked to the connecting shaft.

[0023] When the sub-claw is in the second position, it is separated from the connecting shaft.

[0024] In some embodiments of this utility model, an indoor unit is also provided, which includes the aforementioned air guide assembly.

[0025] In some embodiments of this utility model, an air conditioner is also provided, which includes the above-described air guide assembly.

[0026] The present invention provides an air guide assembly, an indoor unit, and an air conditioner. The air guide assembly has an elastic claw on the side of the connecting rod away from the air guide blade. The elastic claw can be offset between a first position and a second position under the action of external force, thereby locking and separating from the connecting shaft. This allows the air guide blade to be locked and connected or separated from the connecting rod, which ensures the connection stability between the air guide blade and the connecting rod and also realizes the quick assembly and disassembly of the air guide blade and the connecting rod.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] like Figures 1-3As shown, this utility model provides an air guide assembly 10, which includes a connecting rod 100 and an air guide blade 200. The connecting rod 100 is provided with a fixing hole 120 and an elastic claw 110. The fixing hole 120 penetrates the connecting rod 100 along its thickness direction. One end of the elastic claw 110 is connected to the connecting rod 100 and is located at the edge of the fixing hole 120. One end of the air guide blade 200 is provided with a connecting shaft 300, which is inserted into the fixing hole 120 and is located away from the air guide blade. One end of the fan blade 200 is connected to the elastic claw 110; the free end of the elastic claw 110 is configured to be offset from a first position to a second position under the action of an external force, and to return to the first position after the external force is removed. When the free end is in the first position, the connecting shaft 300 is locked to the elastic claw 110 so that the connecting shaft 300 is locked to the fixing hole 120; when the free end is in the second position, the connecting shaft 300 is separated from the elastic claw 110 so that the connecting shaft 300 can be pulled out of the fixing hole 120.

[0037] It should be noted that the end of the elastic claw 110 connected to the connecting rod 100 is a fixed end, and the other end is a free end.

[0038] Understandably, after the connecting shaft 300 passes through the fixing hole 120, as the connecting shaft 300 continues to extend into the fixing hole 120, the portion of the connecting shaft 300 protruding from the fixing hole 120 contacts the elastic claw 110 to lock into place. Since the end of the connecting shaft 300 furthest from the guide vane 200 is locked to the other side of the connecting rod 100 by the elastic claw 110, the connecting shaft 300 cannot be pulled out of the fixing hole 120, thus locking the connecting shaft 300 to the connecting rod 100, thereby connecting the guide vane 200 to the connecting rod 100. 0; When it is necessary to separate the connecting rod 100 and the guide vane 200, the free end of the elastic claw 110 is offset to the second position, so that the elastic claw 110 is separated from the connecting shaft 300, and the connecting shaft 300 can be pulled out of the fixing hole 120, so that the guide vane 200 can be separated from the connecting rod 100; that is, by allowing the free end of the elastic claw 110 to be offset to the first position and the second position, this utility model can not only ensure the connection stability between the guide vane 200 and the connecting rod 100, but also realize the quick assembly and disassembly of the guide vane 200 and the connecting rod 100.

[0039] In some embodiments, the connecting rod 100 is generally provided with a plurality of spaced-apart fixing holes 120, and each fixing hole 120 is provided with a corresponding elastic claw 110. The elastic claw 110 is provided at the end of the connecting rod 100 away from the air guide blade 200, so that after being locked and connected with the connecting shaft 300, the connecting rod 100 and the air guide blade 200 are locked and connected.

[0040] In one embodiment, the elastic claw 110 is a sheet-like structure, with one end connected to the connecting rod 100 and the other end able to shift under external force.

[0041] In some embodiments, the elastic claw 110 has a sheet-like structure, and the thickness of the elastic claw 110 gradually increases from the free end to the end near the connecting rod 100.

[0042] Understandably, by gradually increasing the thickness of the elastic claw 110 from the free end to the end near the connecting rod 100, the strength of the elastic claw 110 is improved, and breakage caused by repeated offsets is avoided.

[0043] In some embodiments, the resilient claw 110 includes at least a plurality of sub-claws 111, which are distributed along the circumferential direction of the fixing hole 120 and spaced apart from each other. The sub-claws 111 are configured to be offset from a first position to a second position under the action of an external force and to be reset to the first position after the external force is removed. When the sub-claws 111 are in the first position, they are locked to the connecting shaft 300. When the sub-claws 111 are in the second position, they are separated from the connecting shaft 300.

[0044] It is understandable that by setting multiple sub-claws 111, multiple positions of the limiting part 320 are abutted, thereby improving the stability of the limiting part 320 by the elastic claw 110 and avoiding the situation where a single sub-claw 111 abutting a single position is prone to displacement and thus causing limiting failure.

[0045] In some embodiments, the length of the connecting shaft 300 is greater than the length of the fixing hole 120, so that the connecting shaft 300 has sufficient length to connect with the elastic claw 110 after passing through the fixing hole 120.

[0046] For example, the length of the connecting shaft 300 is greater than the sum of the length of the fixing hole 120 and the length of the elastic claw 110.

[0047] In some embodiments, the connecting shaft 300 includes a shaft body 310 and a limiting portion 320. The limiting portion 320 is disposed at one end of the shaft body 310 away from the guide vane 200. When the free end is in the first position, the orthographic projection of the free end on the fixing hole 120 is close to the center of the fixing hole 120, so that when the free end is in the first position, it abuts against the end of the limiting portion 320 near the shaft body 310, thus limiting the limiting portion 320 to the other side of the connecting rod 100. When the free end is in the second position, the orthographic projection of the free end on the fixing hole 120 is outside the fixing hole 120, so that when the free end is in the second position, it is away from the limiting portion 320.

[0048] Understandably, the free end abuts against the end of the limiting part 320 near the shaft 310, that is, the free end of the elastic claw 110 abuts against the end of the limiting part 320, thereby preventing the limiting part 320 from moving toward the connecting rod 100, and thus preventing the connecting shaft 300 from being pulled out of the fixing hole 120; wherein, to make the orthographic projection of the free end in the first position close to the center of the fixing hole 120, the elastic claw 110 needs to be tilted, with its free end close to the center of the fixing hole 120, so as to ensure that the free end can abut against the end of the limiting part 320 when in the first position, restricting the limiting part 320 from moving toward the fixing hole 120. The movement of 0 prevents the connecting shaft 300 from being pulled out of the fixing hole 120; the orthographic projection of the free end in the second position is located outside the fixing hole 120. The purpose is to ensure that the free end is away from the limiting part 320 when the free end is in the second position, so that the limiting part 320 can move toward the fixing hole 120 and disengage from the fixing hole 120, thereby allowing the connecting shaft 300 to separate from the fixing hole 120; at the same time, it also ensures that during the process of the connecting shaft 300 being inserted into the fixing hole 120, the limiting part 320 can move smoothly to the side of the free end away from the connecting rod 100, ensuring that the free end can be located at the end of the limiting part 320 after reset.

[0049] In some embodiments, the limiting part 320 is configured to deform under the action of an external force, changing from a first form to a second form, and returning to the first form after the external force is removed; when the limiting part 320 is in the first form, the width of the limiting part 320 is greater than the width of the fixing hole 120; when the limiting part 320 is in the second form, the width of the limiting part 320 is less than the width of the fixing hole 120.

[0050] For example, during the process of inserting the connecting shaft 300 into the fixing hole 120, the limiting part 320 is first switched to the second form so that it can pass smoothly through the fixing hole 120. After passing through the fixing hole 120, it is restored to the first form and restricted to the other side of the fixing hole 120. At the same time, an external force is applied to the elastic claw 110 so that its free end is in the second position, ensuring that the limiting part 320 can move smoothly to the side of the elastic claw 110 away from the connecting rod 100. After it is determined that the limiting part 320 has moved to the side of the elastic claw 110 away from the connecting rod 100, the external force on the elastic claw 110 is removed so that it is reset to the first position and abuts against the end of the limiting part 320, thus completing the connection between the connecting shaft 300 and the connecting rod 100.

[0051] During the process of pulling the connecting shaft 300 out of the fixing hole 120, the limiting part 320 is switched to the second form, the free end of the elastic claw 110 is moved to the second position, and the connecting shaft 300 is pulled out directly.

[0052] It is understandable that when the limiting part 320 is in the first form, its width is greater than the width of the fixing hole 120, and it cannot pass through the fixing hole 120. Then, when the limiting part 320 passes through the fixing hole 120 in the second form, the external force is removed to restore it to the first form, so as to ensure that the connecting shaft 300 can easily disengage from the fixing hole 120. At the same time, since its width is greater than the width of the fixing hole 120, and the free end is close to the center of the fixing hole 120 when it is in the first position, it can be ensured that the free end can abut against the end of the limiting part 320 when it is in the first position.

[0053] In some embodiments, a deformation groove 301 is provided on the connecting shaft 300. The deformation groove 301 extends from the end of the limiting part 320 away from the shaft body 310 along the length direction of the connecting shaft 300 to the shaft body 310, so that the limiting part 320 can be transformed from a first form to a second form under the action of external force, and return to the first form after the external force is removed.

[0054] It is understandable that by opening the deformation groove 301 on the shaft 310, the two sides of the shaft 310 can be pressed together, thereby causing the limiting part 320 to deform, and the width of the limiting part 320 after deformation is smaller than the width before deformation.

[0055] It should be noted that the deformation groove 301 extends to the middle of the shaft 310 at most, so as to reduce the impact of opening the deformation groove 301 on the strength of the shaft 310.

[0056] In some embodiments, the width of the shaft 310 gradually increases from one end near the limiting portion 320 to the other end near the guide vane 200 until it is the same as the width of the fixing hole 120.

[0057] It is understandable that the deformation groove 301 is opened from the end of the limiting part 320 away from the shaft 310 to the shaft 310, and the width of the part of the shaft 310 without the deformation groove 301 gradually increases from the end of the shaft 310 near the deformation groove 301 to the end of the shaft 310 near the connecting rod 100, thereby increasing the strength of the shaft 310 and reducing the impact of opening the deformation groove 301 on the shaft 310.

[0058] In some embodiments, the maximum width of the shaft 310 is limited to the same width as the fixing hole 120 to ensure that the shaft 310 can be properly inserted into the fixing hole 120.

[0059] In some embodiments, the shaft 310 includes a connecting portion 312 and a main body portion 311. The connecting portion 312 is connected between the main body portion 311 and the guide vane 200. The other end of the main body portion 311 is connected to the limiting portion 320. The width of the connecting portion 312 is greater than the width of the main body portion 311 to form a stepped structure. The fixing hole 120 is a stepped shaft hole that mates with the shaft 310.

[0060] It is understandable that by setting the shaft 310 and the fixing hole 120 into a stepped structure that cooperates with each other, when the connecting shaft 300 is connected to the fixing hole 120, the connecting part 312 abuts against the stepped surface on the fixing hole 120, thereby restricting the connecting part 312 from moving away from the guide vane 200. Meanwhile, the limiting part 320 abuts against the elastic claw 110, which can restrict the limiting part 320 from moving towards the side closer to the guide vane 200. Thus, limiting is formed at both ends of the connecting shaft 300, restricting the vertical movement of the connecting shaft 300 and reducing the swaying amplitude of the guide vane 200.

[0061] Specifically, the fixing hole 120 includes a first sub-hole 121 and a second sub-hole 122 connected in sequence. The first sub-hole 121 is located on the side of the second sub-hole 122 that is close to the air guide vane 200. The width of the first sub-hole 121 is greater than the width of the second sub-hole 122. A first stepped surface is formed between the first sub-hole 121 and the second sub-hole 122. A second stepped surface is formed between the connecting part 312 and the main body part 311. When the connecting shaft 300 is connected to the fixing hole 120, the first stepped surface abuts against the second stepped surface to restrict the connecting shaft 300 from moving toward the side away from the air guide vane 200.

[0062] In some embodiments, the present invention also provides an indoor unit, which includes the above-mentioned air guide assembly 10. Since the indoor unit includes the above-mentioned air guide assembly 10, that is, includes some or all of the above-mentioned air guide assembly 10 embodiments, the air conditioner has the beneficial effects of some or all of the above-mentioned air guide assembly 10 embodiments, which will not be described in detail here.

[0063] In some embodiments, the present invention also provides an air conditioner that includes the air guide assembly 10 described above. Since the air conditioner has the air guide assembly 10, that is, includes some or all of the embodiments of the air guide assembly 10, the corresponding air conditioner has the beneficial effects of some or all of the embodiments of the air guide assembly 10.

[0064] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made based on the contents of the present utility model specification and drawings under the application concept of the present utility model, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
