Description

Technical Field

[0001] This application relates to the field of product testing technology, such as a method and apparatus, testing system, and storage medium for testing air outlet grilles. Background Technology

[0002] Currently, in pursuit of greater air volume and longer air delivery distance, existing cabinet air conditioners typically feature large indoor unit air outlet grilles, resulting in insufficient strength of the grille bars. Furthermore, the grille is made of injection-molded material, which has insufficient heat resistance. During heating operation, the air outlet grille is prone to twisting, deformation, or even partial breakage due to concentrated thermal stress.

[0003] The related technology discloses an air conditioner air outlet panel assembly, including an air outlet panel, an air outlet grille fixedly disposed at the air outlet position of the air outlet panel and covering the air outlet; the air outlet grille includes a grille mesh and a surrounding rib fixedly disposed around the grille mesh; the outer surface of the surrounding rib protrudes from the surface of the grille mesh, and the surrounding rib includes an inner protruding rib located inside the air outlet, the inner protruding rib being flush with the outer surface of the air outlet panel.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] While the above solution increases the strength of the air outlet grille by reinforcing ribs, the design of these ribs relies on engineering experience and requires thermal deformation testing using prototype parts. Designing an air outlet grille based on engineering experience introduces significant uncertainty, necessitating repeated modifications and improvements during the verification process. This results in high R&D costs and a long development cycle for the air outlet grille.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0013] Optionally, the deformation degree of the air outlet grille is determined based on the deformation degree of all longitudinal bars, including: obtaining the number of non-conforming longitudinal bars; calculating the proportion of the non-conforming number to the total number; if the proportion is greater than a proportion threshold, determining that the deformation degree of the air outlet grille does not meet the usage requirements; if the proportion is less than or equal to the proportion threshold, determining that the deformation degree of the air outlet grille meets the usage requirements.

[0014] Optionally, the actual number of horizontal bars can be determined based on the degree of deformation, including: if the degree of deformation of the air outlet grille does not meet the usage requirements, determining that the number of horizontal bars is insufficient; increasing the number of horizontal bars until the degree of deformation of the air outlet grille meets the usage requirements.

[0019] The method, apparatus, testing system, and storage medium for testing air outlet grilles provided in this disclosure can achieve the following technical effects:

[0020] By determining the number of horizontal bars, the overall structural design of the air outlet grille is established. Based on the actual operating conditions of the air outlet, the degree of deformation of the current structural design is assessed. The acceptable level of deformation is then used to determine whether the current number of horizontal bars meets the strength requirements.

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0039] In the disclosed embodiments, the terminal device refers to an electronic device with wireless connectivity.

[0040] Combination Figure 1 As shown in the figure, this disclosure provides a schematic diagram of the structure of an air outlet grille, which includes a plurality of longitudinal grilles distributed in the horizontal direction and a plurality of transverse grilles distributed in the vertical direction.

[0041] in, Figure 1 The air outlet grille 10 shown consists of several longitudinal grilles 11 and three transverse grilles 12. It should be noted that for air outlet grilles with more transverse grilles 12 and fewer longitudinal grilles 11, the same solution can be used to perform air outlet grille testing after replacing the two.

[0042] Combination Figure 1 The present disclosure provides a method for testing air outlet grilles, as shown in the illustration. Figure 2 As shown, the above method includes:

[0043] S210, the processor obtains the number of horizontal bars.

[0044] S220: The processor determines the structure of the air outlet grille based on the number of horizontal bars.

[0045] S230: The processor determines the degree of deformation of the air outlet grille arranged according to the structural scheme based on the operating condition information of the air outlet.

[0046] S240: The processor determines the actual number of transverse bars based on the degree of deformation.

[0047] The method for testing air outlet grilles provided in this disclosure can assist designers in grille design by determining whether the number of transverse grilles is sufficient. In the illustrated air outlet grille, the transverse grilles primarily reinforce the longitudinal grilles to prevent them from deforming due to heat. However, while adding too many transverse grilles can effectively prevent thermal deformation of the longitudinal grilles, it increases manufacturing costs while affecting aesthetics. Therefore, by obtaining the number of transverse grilles, the overall structural scheme of the air outlet grille is determined. Based on the actual operating conditions of the air outlet that the air outlet grille will face, the degree of deformation of the current structural scheme is determined. By assessing the acceptable degree of deformation, it is determined whether the current number of transverse grilles meets the strength requirements.

[0048] The operating condition information for the air outlet can be the air conditioner's extreme heating process, i.e., the operating process during which the air outlet temperature is highest. Alternatively, it can be the operating process where most users adjust the air outlet temperature to its maximum during use. The acceptable level of deformation includes whether it affects the angle of the airflow from the outlet, or whether the degree of deformation is perceptible to the naked eye.

[0049] Optionally, the processor determines the structural scheme of the air outlet grille based on the number of horizontal bars, including: the processor determining the distribution rule of the horizontal bars based on the boundary conditions of the air outlet grille; and the processor determining the structural scheme of the grille based on the number and distribution rule of the horizontal bars.

[0050] The boundary conditions include the length, width, and installation method of the grille.

[0051] This allows for accurate determination of the deformation degree of the air outlet grille. Based on the width of the grille, the required number and distribution of longitudinal bars can be determined. Based on the length of the grille, the strength requirements for each node of the longitudinal bars can be determined. Furthermore, the installation method of the grille reveals the overall stress distribution on the entire grille. Based on the stress distribution of the longitudinal bars, a suitable number and distribution pattern of transverse bars are selected from a pre-set database to ensure that the stress distribution at each node meets its usage requirements. For example, the transverse bars can cover as many nodes prone to high temperatures as possible; or the transverse bars can be evenly distributed. This results in a complete structural scheme for the air outlet grille.

[0052] Optionally, the processor determines the distribution rule of the transverse gratings based on the number of longitudinal gratings and the boundary conditions of the air outlet grille. The processor then determines the structural scheme of the grille based on the number of transverse gratings and their distribution rule.

[0053] This allows for accurate determination of the deformation degree of the air outlet grille. Based on the number of longitudinal bars and the boundary conditions of the air outlet grille, the stress on the longitudinal bars can be determined more quickly. Then, based on the stress on the longitudinal bars and the number of transverse bars, a suitable distribution rule for the transverse bars is selected, thus obtaining a complete structural scheme for the air outlet grille.

[0054] The distribution of the horizontal bars can be uniform along the vertical direction. Alternatively, the spacing between the horizontal bars can be arithmetic or geometrically equal, starting from the top or bottom surface of the air outlet grille. Another option is that the spacing between the horizontal bars can be arithmetic or geometrically equal, extending from the center plane of the air outlet grille towards the top or bottom surface. The specific distribution rule can be set by the user according to their needs.

[0055] Optionally, the processor determines the degree of deformation of the air outlet grille arranged according to the structural scheme based on the operating condition information of the air outlet, including: the processor determining the temperature distribution at the air outlet based on the operating condition information of the air outlet; the processor obtaining the degree of deformation of each longitudinal grille based on the temperature distribution; and the processor determining the degree of deformation of the air outlet grille based on the degree of deformation of all longitudinal grilles.

[0056] This allows for a better assessment of whether the strength of the air outlet grille meets usage requirements. Based on the operating conditions of the air outlet, the temperature distribution at the outlet under the current conditions is determined. This allows for the determination of the deformation degree of each longitudinal grille under that temperature distribution. Based on the deformation degree of each longitudinal grille bar, the overall deformation degree of the air outlet grille is determined. Since the temperature distribution at the air outlet varies under different operating conditions, and to ensure testing efficiency, the test can be conducted under the condition with the highest local temperature.

[0057] Optionally, the processor determines the degree of deformation of each longitudinal grid strip based on the temperature distribution, including: the processor calculates the thermal deformation of each longitudinal grid strip according to the temperature distribution. Longitudinal grid strips with thermal deformation greater than or equal to a deformation threshold are identified as unqualified.

[0058] In this way, quantifying thermal deformation makes judging the deformation of the grille simpler. If the thermal deformation is greater than or equal to the deformation threshold, it is determined that the deformation of the current longitudinal grille is too great and cannot meet the user's needs. That is, in the current state, the deformation of the longitudinal grille has affected the air outlet angle, or the user can visually observe that the longitudinal grille has deformed.

[0059] Optionally, the thermal deformation can be the deformation angle or deformation distance of the grid strips. The deformation angle is defined by taking the intersection of the transverse and longitudinal grid strips at room temperature as the vertex, the initial position of the longitudinal grid strip at room temperature as one side of the deformation angle, and the position of the longitudinal grid strip when it deviates from its initial position as the other side of the deformation angle. The deformation distance is the point furthest perpendicularly from the initial position of a single longitudinal grid strip in its deformed state, or the distance of a line segment projected vertically onto a single horizontal plane.

[0060] Specifically, taking the deformation distance as an example, the point furthest from the initial position of a single longitudinal grid bar under deformation is considered as the thermal deformation. If the perpendicular distance from any point on the longitudinal grid bar to its initial position is greater than the deformation threshold, the longitudinal grid bar is determined to not meet the usage requirements. The deformation threshold ranges from [2.8, 3.5] mm, specifically, it can be 2.9 mm, 3 mm, or 3.25 mm.

[0061] Combination Figure 3 As shown, this disclosure provides another method for testing air outlet grilles, including:

[0062] S310, the processor obtains the number of horizontal bars.

[0063] The S320 processor determines the structure of the air outlet grille based on the number of horizontal bars.

[0064] The S330 processor determines the degree of deformation of the air outlet grille arranged according to the structural scheme based on the operating condition information of the air outlet.

[0065] In the S340, if the deformation of the air outlet grille does not meet the usage requirements, the processor adjusts the distribution of the horizontal grille bars according to the temperature distribution.

[0066] In the S350, if the deformation of the adjusted air vent grille does not meet the usage requirements, the processor determines that the number of horizontal grille bars is insufficient.

[0067] S360, the processor controls the increase in the number of horizontal bars.

[0068] The method for testing air outlet grilles provided in this disclosure avoids unnecessary increases in the number of horizontal grilles. When the deformation of the air outlet grille does not meet usage requirements, the distribution of the horizontal grilles is optimized and adjusted based on the temperature distribution to better approximate nodes with significant deformation. The temperature distribution can be determined based on the operating conditions of the air outlet, or it can be the temperature distribution during simulation or actual testing. If the temperature distribution during actual simulation or testing differs from the temperature distribution determined based on the operating conditions of the air outlet, the temperature distribution during simulation or actual testing is updated to reflect the current operating conditions of the air outlet to improve the accuracy of subsequent parameter calls. If the deformation of the adjusted air outlet grille still does not meet usage requirements, it is determined that the current number of horizontal grilles is insufficient to meet the requirements. In this case, the number of horizontal grilles is increased; the increase can be one, or multiple grilles can be added depending on the actual deformation. No specific limitation is made. For example, if the deformation of the vertical grille exceeds the upper limit of deformation, two horizontal grilles are added. The upper limit of deformation is greater than the deformation threshold.

[0069] Combination Figure 4 As shown, this disclosure provides another method for testing air outlet grilles, including:

[0070] S410, the processor obtains the number of horizontal bars.

[0071] The S420 processor determines the structure of the air outlet grille based on the number of horizontal bars.

[0072] The S430 processor obtains the number of defective vertical grilles based on the operating conditions of the air outlet.

[0073] S440, the processor calculates the percentage of defective items out of the total number of items.

[0074] S450, the processor determines whether the ratio value is greater than the ratio threshold. If yes, proceed to step S461; otherwise, proceed to step S470.

[0075] The S460 processor determines the degree of deformation of the air vent grille to meet usage requirements.

[0076] S470, the processor determined that the deformation of the air vent grille did not meet the usage requirements.

[0077] The method for testing air outlet grilles provided in this disclosure avoids excessive horizontal grille deformation due to deformation in small areas. By obtaining the number of defective vertical grilles and calculating the proportion of defective grilles to the total number, it is determined whether excessively deformed vertical grilles will affect the overall airflow effect or appearance. If the proportion is less than or equal to a proportion threshold, it is determined that the current number of deformed vertical grilles does not affect the overall airflow effect or appearance of the air outlet grille. That is, the current number of horizontal grilles is appropriate, and the structure of the air outlet grille is appropriate. If the proportion is greater than the proportion threshold, it is determined that the current number of deformed vertical grilles will affect the overall airflow effect or appearance of the air outlet grille. That is, the current number of horizontal grilles is inappropriate, and the structure of the air outlet grille does not meet the usage requirements. The proportion threshold ranges from [25, 40]%, specifically 28%, 30%, or 33%.

[0078] Optionally, the processor determines the actual number of horizontal bars based on the degree of deformation, including: if the degree of deformation of the air outlet grille does not meet the usage requirements, the processor determines that the number of horizontal bars is insufficient. The processor increases the number of horizontal bars until the degree of deformation of the air outlet grille meets the usage requirements.

[0079] In this way, the system can automatically increase the number of horizontal bars and conduct relevant tests to obtain the most suitable number of horizontal bars. This effectively avoids the significant uncertainties associated with designing air outlet grilles based on engineering experience, thus improving the practicality and efficiency of the design.

[0080] Combination Figure 5 As shown, this disclosure provides another method for testing air outlet grilles, including:

[0081] S510, the processor obtains the number of horizontal bars.

[0082] In the S520, the processor determines the structural scheme of the air outlet grille based on the number of horizontal bars.

[0083] The S530 processor obtains the number of defective vertical grilles based on the operating conditions of the air outlet.

[0084] S540, the processor calculates the percentage of defective items out of the total number of items.

[0085] S550, the processor determines whether the ratio value is greater than the ratio threshold. If yes, proceed to step S551; otherwise, proceed to step S552.

[0086] S551, the processor determined that the deformation of the air vent grille did not meet the usage requirements.

[0087] S560, the processor determines whether the number of distribution state adjustments is less than the threshold. If yes, proceed to step S561; otherwise, proceed to step S562.

[0088] S561, the processor adjusts the distribution state of the horizontal grid bars according to the temperature distribution; and then returns to step S530.

[0089] S562, the processor controls the number of horizontal bars to increase by one.

[0090] The S552 processor determines the degree of deformation of the air vent grille to meet usage requirements.

[0091] The S553 processor sends the air vent grille design to the user.

[0092] The method for testing air outlet grilles provided in this disclosure can effectively reduce the R&D cost and shorten the R&D cycle of air outlet grille design. The corresponding structural scheme of the air outlet grille is determined automatically by the number of horizontal grilles. Based on the operating conditions of the air outlet, the number of defective vertical grilles is obtained to determine whether the current structural scheme meets the usage requirements. If the proportion of defective vertical grilles to the total number of vertical grilles is greater than a threshold, the structure of the air outlet grille is optimized. If the optimization still fails to meet the usage requirements, the number of horizontal grilles is increased by one. To avoid multiple optimizations of the air outlet grille structure, it is determined whether the number of adjustment cycles is less than a threshold. If the number of adjustments is greater than or equal to the threshold, it is considered that the optimization limit of the current number of horizontal grilles has been reached. At this time, structural optimization is no longer performed, and the number of horizontal grilles is increased. If the proportion of defective vertical grilles to the total number of vertical grilles is less than or equal to a threshold, the current structure is deemed suitable, and the current air outlet grille structural scheme is sent to the user. The number of horizontal grilles can be tested starting from 0.

[0093] Optionally, if the proportion of defective longitudinal bars to the total number of longitudinal bars is less than or equal to a threshold, the processor reduces the number of transverse bars and then re-evaluates. If the exhaust grille structure cannot meet the usage requirements, the processor outputs the exhaust grille structure before reducing the number of transverse bars, to avoid having too many transverse bars initially during the initial evaluation.
