Description

Technical Field

[0001] This utility model belongs to the field of air conditioner technology, specifically relating to a protective pad and an air conditioner. Background Technology

[0002] Currently, split-type wall-mounted indoor units generally use cross-flow fan blade air supply components. Their air outlet area typically has at least one support bracket, used to connect the upper and lower structures and serve as the load-bearing component for the rotation axis of the fan blades. During air conditioner transportation and shaking, the cross-flow fan blades are prone to collision with the support bracket, leading to cracks and defects in the blades. Existing technology often avoids collisions by increasing the distance between the cross-flow fan blades and the support bracket. However, as product designs become more compact, the distance between the support bracket and the fan blades should not be too large; reducing the size of the cross-flow fan blades would decrease the airflow volume, degrading the user experience.

[0003] How to avoid collisions between the cross-flow fan blades and the support frame without changing the existing cross-flow fan blades or increasing the distance between the cross-flow fan blades and the support frame is a technical problem that urgently needs to be solved. Utility Model Content

[0004] Therefore, this utility model provides a protective pad and an air conditioner that avoids collision between the cross-flow fan blades and the support bracket without changing the existing cross-flow fan blades or increasing the distance between the cross-flow fan blades and the support bracket.

[0005] On one hand, this utility model provides a protective pad for use in an air conditioner indoor unit. The air conditioner indoor unit includes a housing, a cross-flow fan blade disposed within the housing, and an air outlet disposed within the housing. The length direction of the air outlet is a first direction, and the width direction of the air outlet is a second direction. The air outlet is provided with a support rod extending along the second direction and fixed to the housing. The air outlet is also provided with a connecting rod extending along the first direction. The support rod is located between the connecting rod and the cross-flow fan blade, and a gap is provided between the support rod and the cross-flow fan blade. The protective pad is provided with a clearance groove. The protective pad includes a first buffer portion adjacent to the clearance groove. The support rod is inserted into the clearance groove, and a portion of the protective pad is located within the gap. Of the two opposite sides of the first buffer portion, the first side abuts against the connecting rod, and the second side abuts against the cross-flow fan blade.

[0006] In some embodiments, a volute is provided inside the housing, and an airflow channel is provided between the volute and the bottom of the cross-flow fan blade. The airflow channel is in communication with the gap, and the protective pad includes a second buffer portion disposed inside the airflow channel.

[0007] In some embodiments, the end of the second buffer portion facing away from the first buffer portion is pointed in the axial direction projection of the cross-flow fan blade.

[0008] In some embodiments, the second buffer portion is arc-shaped in the projection of the cross-flow fan blade in the axial direction, and the concave surface of the second buffer portion contacts the cross-flow fan blade.

[0009] In some embodiments, the support rod is provided with a first hinge portion, the air outlet is provided with an air guide plate, the air guide plate is provided with a second hinge portion, and the second hinge portion is hingedly connected to the first hinge portion; the protective pad is provided with a receiving groove, and the first hinge portion is located in the receiving groove.

[0010] In some embodiments, the protective pad is provided with a third buffer portion. When the air guide plate opens the air outlet, the third buffer portion is disposed between the second hinge portion and the air guide plate and abuts against the air guide plate to keep the air outlet in an open state.

[0011] In some embodiments, the protective pad is provided with an opening that communicates with the receiving groove and faces a first direction.

[0012] In some embodiments, the receiving groove is in communication with the relief groove.

[0013] In some embodiments, the protective pad is elastic.

[0014] On the other hand, this utility model provides an air conditioner, including an indoor unit and the aforementioned protective pad, the protective pad being disposed inside the indoor unit.

[0015] This application provides a protective pad between the cross-flow fan blade and the support rod. The two sides of the first buffer part of the protective pad abut against the cross-flow fan blade and the connecting rod, respectively, thereby preventing collisions between the cross-flow fan blade and the support rod.

[0019] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0020] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0021] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0022] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0023] Currently, split-type wall-mounted indoor air units generally use cross-flow fan blade assembly. Their air outlet area typically has at least one support bracket to connect the upper and lower structures and serve as the load-bearing component for the rotation axis of the guide vanes. To achieve left-right airflow, a guide vane assembly is located along the lower edge of the air outlet. However, during actual transportation and drops, the axial fan blades are prone to collisions with the guide vanes or support brackets, leading to cracks and defects in the blade structure. Furthermore, after a drop, the guide vane is prone to detachment due to shaking.

[0024] To address the issue of fan blade damage, existing technologies typically mitigate this problem by adjusting the material thickness inside the support bracket to increase the fan blade clearance or by reducing the size of the guide vanes. However, as product designs become more compact, the clearance between the air outlet support structure and the fan blades is nearing its limit, and reducing the size of the guide vanes decreases the sweeping range, impacting the user experience. Regarding the issue of guide vanes detaching, existing technologies usually involve reinforcing the guide vane's fixation, but this makes assembly more difficult during manufacturing. Alternatively, adding adhesive tape to the outside of the guide vane can be problematic, as this tape solution is difficult to securely fix to frosted panels.

[0025] How to avoid collisions between cross-flow fan blades and support brackets without altering existing cross-flow fan blades, increasing the distance between cross-flow fan blades and support brackets, or changing the structural strength of cross-flow fan blades is a pressing technical problem that needs to be solved.

[0026] See also Figure 1-12 As shown, according to an embodiment of this utility model, a protective pad 1 is applied to an indoor unit of an air conditioner. The indoor unit includes a housing 2, a cross-flow fan 3 is disposed inside the housing 2, and an air outlet 201 is disposed in the housing 2. The length direction of the air outlet 201 is a first direction, and the width direction of the air outlet 201 is a second direction. The air outlet 201 is provided with a support rod 401 extending along the second direction and fixed to the housing 2. The air outlet 201 is also provided with a connecting rod 402 extending along the first direction. The rod 401 is located between the connecting rod 402 and the cross-flow fan blade 3. A gap is provided between the support rod 401 and the cross-flow fan blade 3. The protective pad 1 is provided with a relief groove 104. The protective pad 1 includes a first buffer part 101 adjacent to the relief groove 104. The support rod 401 is inserted into the relief groove 104. A portion of the protective pad 1 is located within the gap. Of the two opposite sides of the first buffer part 101, the first side abuts against the connecting rod 402, and the second side abuts against the cross-flow fan blade 3.

[0027] This application, by partially placing the protective pad 1 within the interval, with the two sides of the first buffer part 101 abutting against the cross-flow fan blade 3 and the connecting rod 402 respectively, avoids collisions between the cross-flow fan blade 3 and the support rod 401 when the indoor unit of the air conditioner is vibrated due to transportation, handling, drops, or other reasons. This prevents cracks or breaks in the cross-flow fan blade 3 caused by collisions with the support rod 401, ensuring the integrity of the cross-flow fan blade 3 and reducing the transportation cost of the indoor unit of the air conditioner. This application does not require increasing the distance between the cross-flow fan blade 3 and the support rod 401, nor does it require reducing the size of the cross-flow fan blade 3, effectively ensuring the compactness of the indoor unit of the air conditioner and the air volume delivered by the cross-flow fan blade 3, which is beneficial to improving the user experience.

[0028] Preferred, such as Figure 2 , Figure 3 As shown, a volute 6 is provided inside the housing 2, and an airflow channel 202 is provided at the bottom of the volute 6 and the cross-flow fan blade 3. The airflow channel 202 is connected to the spacer. The protective pad 1 includes a second buffer part 102, which is disposed inside the airflow channel 202.

[0029] Furthermore, the support rod 401 is positioned in the middle of the air outlet 201 in the first direction.

[0030] During transportation, air conditioner indoor units are generally placed according to the orientation of the air conditioner during use. The two ends of the cross-flow fan blade 3 are rotatably connected to the housing 2 (indirect or direct connection). Under the influence of gravity, combined with bumps, vibrations, or drops, the middle part of the cross-flow fan blade 3 bends downward. When the downward bending of the middle part of the cross-flow fan blade 3 is severe, it will directly cause the cross-flow fan blade 3 to contact or collide with the inner wall of the volute 6, resulting in damage to the cross-flow fan blade 3. If the cross-flow fan blade 3 is bent downward for a long time without rotating, it may cause irreversible deformation, which will make it difficult for the cross-flow fan blade 3 to rotate. This application effectively avoids contact and collision between the cross-flow fan blade 3 and the volute 6 by setting the second buffer part 102 in the air flow channel 202, thereby improving the safety of transporting the air conditioner indoor unit; it also effectively ensures the integrity of the overall structure of the cross-flow fan blade 3, avoids irreversible deformation, and is conducive to the stable rotation of the cross-flow fan blade 3.

[0031] Preferably, the two opposite surfaces of the second buffer section 102 are in contact with the inner wall surfaces of the cross-flow fan blade 3 and the volute 6, respectively.

[0032] Preferably, in the projection of the cross-flow fan blade 3 in the axial direction, the end of the second buffer portion 102 facing away from the first buffer portion 101 is pointed.

[0033] By making the end of the second buffer part 102 facing away from the first buffer part 101 pointed, it is easier for the protective pad 1 to be inserted into the air flow channel 202, thus avoiding the phenomenon that the protective pad 1 is stuck by the cross-flow fan blade 3 during installation.

[0034] Preferred, such as Figure 2 , Figure 3 As shown, in the projection of the cross-flow fan blade 3 in the axial direction, the second buffer part 102 is arc-shaped, and the concave surface of the second buffer part 102 is in contact with the cross-flow fan blade 3.

[0035] By setting the concave surface of the second buffer portion 102 to face the cross-flow fan blade 3, the contact area between the second buffer portion 102 and the cross-flow fan blade 3 is increased, thereby increasing the effective area between the second buffer portion 102 and the cross-flow fan blade 3, and thus improving the protective performance of the second buffer portion 102 on the cross-flow fan blade 3.

[0036] Preferably, the radius of the concave surface of the second buffer section 102 is the same as the radius of the distribution circle of the cross-flow fan blade 3.

[0037] Preferred, such as Figure 2 , Figure 3 and Figure 9 , Figure 10 , Figure 11 As shown, the support rod 401 is provided with a first hinge part, the air outlet 201 is provided with an air guide plate 5, the air guide plate 5 is provided with a second hinge part, and the second hinge part is hingedly connected to the first hinge part; the protective pad 1 is provided with a receiving groove 105, and the first hinge part is located in the receiving groove 105.

[0038] In this application, "up and down" and "left and right" refer to the orientation when observing the indoor unit of the air conditioner from the front of the air-conditioned room.

[0039] By setting the receiving groove 105, on the one hand, interference between the protective pad 1 and the first hinge and the second hinge can be avoided; on the other hand, the first hinge and the second hinge are locked in the receiving groove 105, and the receiving groove 105 limits the protective pad 1, preventing the protective pad 1 from moving up, down, left and right, which can improve the stability of the protective pad 1 and effectively prevent the phenomenon that the protective pad 1 will not be able to effectively protect the cross-flow fan blade 3 when the air conditioner indoor unit is transported, vibrated, or dropped.

[0040] Preferred, such as Figure 2 , Figure 3 and Figure 9 , Figure 10 , Figure 11 As shown, the protective pad 1 is provided with a third buffer part 103. When the air guide plate 5 opens the air outlet 201, the third buffer part 103 is disposed between the second hinge part and the air guide plate 5 and abuts against the air guide plate 5 to make the air outlet 201 open.

[0041] When installing the protective pad 1, the air guide plate 5 needs to be opened and installed from the air outlet 201. After the protective pad 1 is installed, the third buffer part 103 is locked between the second hinge part (which is also the first hinge part) and the air guide plate 5. Since the air outlet 201 is in the open state, on the one hand, the third buffer part 103 can prevent the air guide plate 5 from shaking, and plays a role in limiting the air guide plate 5, so as to prevent the air guide plate 5 from vibrating and deforming or even falling off during the transportation of the air conditioner indoor unit; on the other hand, the opening of the air outlet 201 makes it easy to observe the setting of the protective pad 1 when installing the air conditioner, and prevent forgetting to remove the protective pad 1.

[0042] Furthermore, since both the first hinge and the second hinge are located within the receiving groove 105, it is equivalent to a portion of the support rod 401 being located within the receiving groove 105. The support rod 401 abuts against the side wall of the receiving groove 105, thereby limiting the protective pad 1, thus improving the stability of the protective pad 1, and consequently improving the stability of the air guide plate 5.

[0043] The inclusion of the receiving slot 105 also facilitates personnel operation of the protective pad 1, improving assembly efficiency.

[0044] Preferred, such as Figure 2 , Figure 3 and Figure 9 , Figure 10 , Figure 11 As shown, the protective pad 1 is provided with an opening, which communicates with the receiving groove 105 and faces the first direction.

[0045] By providing an opening that faces the first direction, the installation of the protective pad 1 is facilitated. Specifically, when installing the protective pad 1, the first hinge portion of the protective pad 1 is inserted into the receiving groove 105 through the opening.

[0046] Preferred, such as Figure 2 , Figure 3 and Figure 9 , Figure 10 , Figure 11 As shown, the receiving groove 105 is connected to the relief groove 104.

[0047] By connecting the receiving groove 105 with the relief groove 104, it is convenient to install the protective pad 1. After the first hinge part is inserted into the receiving groove 105, the protective pad 1 is moved in a direction away from the cross-flow fan blade 3, so that the support rod 401 can be inserted into the relief groove 104.

[0048] Preferably, the protective pad 1 is elastic.

[0049] When the protective pad 1 is not elastic, the cross-flow fan blade 3 is in direct contact with the solid structure, which can prevent the cross-flow fan blade 3 from shaking during the movement of the air conditioner indoor unit; furthermore, the protective pad 1 is made to be elastic, so that when the air conditioner indoor unit experiences a large vibration, such as a drop, the protective pad 1 can cushion the cross-flow fan blade 3 and improve the protection of the cross-flow liquid distribution.

[0050] Furthermore, the protective pad 1 can be made of rubber or silicone, or it can be made of pearl cotton, which can take into account both cushioning performance and structural strength requirements.

[0051] The connecting rod 402 is equipped with sweeping blades, and the protective pad 1 can also prevent the cross-flow fan blade 3 from contacting or colliding with the sweeping blades.

[0052] During the fall of the indoor unit, the cross-flow fan blade 3 bends and deforms in the middle, colliding with the support rod 401 or the sweeping blades, causing the cross-flow fan blade 3 to crack. By making the protective pad 1 elastic, the protective pad 1 can absorb the impact energy, effectively preventing the cross-flow fan blade 3 from cracking due to collision when the indoor unit falls, while limiting the deformation size of the fan blade and improving structural reliability.

[0053] During the fall of the indoor unit of the air conditioner, the air guide plate 5 shakes and falls off. The two sides of the second buffer part 102 abut against the cross-flow fan blade 3 and the volute 6 respectively. The clearance groove 104 cooperates with the support rod 401, and the receiving groove 105 cooperates with the first hinge part to limit the protective pad 1. This double protection ensures the stable fixation of the protective pad 1, prevents the air guide plate 5 from shaking and falling off, and also avoids the protective pad 1 from shifting or falling off during transportation or installation.

[0054] Installation process of protective pad 1: First, rotate the air guide plate 5 of the air conditioner counterclockwise towards the inside of the air outlet 201 so that the air outlet 201 is fully exposed in front of the operator; Second, confirm the gap position between the connecting rod 402 and the cross-flow fan blade 3 to ensure that the protective pad 1 can be inserted smoothly.

[0055] Third, insert the protective pad 1 into the airflow channel 202 through the gap between the connecting rod 402 and the cross-flow fan blade 3 from the left side of the support rod 401 of the air guide plate 5; Fourth, adjust the position of the protective pad 1 so that the convex arc surface of the second buffer part 102 fits against the inner arc surface of the volute 6, and the lower part of the third buffer part 103 contacts the lower inclined surface of the air outlet 201, ensuring that the protective pad 1 is stably embedded in the airflow channel 202. Fifth, move the protective pad 1 to the right side of the connecting rod 402 until the left side of the receiving groove 105 contacts the left side of the connecting rod 402, thereby limiting the protective pad 1 in the lateral direction; Sixth, fix the left and right movement of the protective pad by the cooperation of the receiving groove 105 of the protective pad 1 and the connecting rod 402, preventing it from shifting during transportation or falling. Seventh, drag the protective pad 1 outward along the receiving groove 105. At this time, the third buffer part 103 abuts against the air guide plate 5, so that the connecting rod 402 enters the relief groove 104. The first hinge part abuts against the front and rear (position when the person stands in front of the indoor unit) side walls of the receiving groove 105 in the receiving groove 105 to achieve further limiting.

[0056] After the third buffer section 103 comes into contact with the air guide plate 5, the air guide plate 5 is squeezed and limited to prevent it from shaking or falling off during transportation.

[0057] Specifically, the protective pad 1 has a rectangular overall shape. The lower side of the first buffer part 101 is provided with a support rib. The support rib is in contact with the connecting rod 402 to ensure that the protective pad 1 is stably connected with the connecting rod 402 at the air outlet 201.

[0058] Furthermore, such as Figure 11As shown, the overall thickness of the protective pad 1 is preferably h≥5mm, the overall length L≥50mm, the length L1 of the relief groove 104 structure in the front-to-back direction is ≥10mm, and the width d of the receiving groove 105 is ≥5mm.

[0059] This utility model also provides an air conditioner, including an indoor unit and the aforementioned protective pad 1, wherein the protective pad 1 is disposed inside the indoor unit.

[0060] The cross-flow fan blades 3 are well protected during transportation and drops. The protective pad 1 does not require modification of the existing fan blades or air guide plate 5 structure. The indoor unit of the air conditioner in this application is relatively compact, meeting the industry's requirements for lightweight and high reliability.

[0061] In a simulated drop test with the protective pad 1 installed in the indoor unit of the air conditioner, the protective pad 1 effectively absorbed the impact energy of the cross-flow fan blade 3, and the blade remained intact; the air guide plate 5 did not shake or fall off due to the support of the receiving groove 105 and the connecting rod 402.

[0062] It will be readily understood by those skilled in the art that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0063] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
