Abstract

The application relates to a mesh cover and an outdoor device, the mesh cover comprising a cover body, the cover body being provided with a heat exchange hole penetrating through in a first direction, and at least one side surface of the cover body in the first direction being provided with a hydrophobic coating. The mesh cover is provided with the hydrophobic coating on at least one side surface of the cover body in the first direction. The hydrophobic coating is arranged on the surface of the cover body, so that liquid is not easy to adhere to the surface, and the liquid can slide in the form of water beads on the surface of the cover body, thereby avoiding the formation of ice columns on the surface of the cover body.

Description

Technical Field

[0001] This application relates to the field of air conditioning equipment technology, and in particular to a mesh cover and outdoor equipment. Background Technology

[0002] Typically, a heat pump air conditioner consists of an indoor unit and an outdoor unit. When the air conditioner is in heating mode, the heat exchanger of the outdoor unit absorbs heat from the outside. Therefore, moisture in the external environment will condense and frost on the outdoor unit. Especially in cold regions, where the air temperature is very low and the outside environment is humid or rainy / snowy, moisture in the air will frost and ice on the air outlet grille during the outdoor unit's heating operation. If the freezing situation continues to worsen, the grille will be blocked or covered by ice, reducing the effective heat exchange area and thus reducing the heating capacity. Utility Model Content

[0003] Therefore, it is necessary to provide a mesh cover and outdoor equipment to address the problem of frost and ice formation on the air outlet mesh cover caused by moisture in the air.

[0004] A mesh cover, the mesh cover comprising:

[0005] The cover has heat exchange holes that extend through it in a first direction, and a hydrophobic coating is provided on at least one side surface of the cover in the first direction.

[0006] In one embodiment, the hydrophobic coating is made of fluoride and silicon dioxide.

[0007] In one embodiment, the hydrophobic coating is configured to be deposited on the surface of the cover via an electrophoretic process.

[0008] In one embodiment, the cover includes two ends disposed opposite each other in a third direction intersecting a first direction, and a middle portion located between the two ends, at least one of the ends and the middle portion having a height difference in the first direction.

[0009] In one embodiment, at least one of the ends has a smooth surface transition with the middle portion.

[0010] In one embodiment, at least one of the surfaces between the end and the middle portion is curved.

[0011] In one embodiment, the cover includes a plurality of support beams spaced apart along a second direction, each of the support beams extending longitudinally along a third direction, and the heat exchange holes are formed between two adjacent support beams. The first direction, the second direction, and the third direction intersect each other but are not coplanar.

[0012] In one embodiment, the cover further includes fixed beams, all of which extend longitudinally along the second direction and are connected to each of the supporting beams.

[0013] In one embodiment, the fixed beam further includes two assembly beams, which are spaced apart along the third direction. Each of the support beams is connected to the two assembly beams at both ends of the third direction, and at least one assembly beam has a mounting hole at at least one end in the second direction.

[0014] In one embodiment, the mesh cover further includes two crossbeams, which are spaced apart along the second direction. Each assembly beam is located between the two crossbeams at both ends in the second direction. Each crossbeam has two fixing holes spaced apart along the third direction, and each fixing hole is aligned with one of the mounting holes.

[0015] In one embodiment, the cover further includes two reinforcing beams, the diameter of which is larger than that of the supporting beam. The two reinforcing beams are spaced apart along the second direction, and all the supporting beams are located between the two reinforcing beams. Each reinforcing beam is connected to the two assembly beams at both ends in the third direction.

[0016] In one embodiment, the cover further includes a side beam, at least one of the reinforcing beams extending longitudinally along a curve, the side beams extending longitudinally along the third direction, and the two ends of the side beams being connected to the reinforcing beams respectively.

[0017] An outdoor device comprising a net as described in any of the preceding claims.

[0018] The aforementioned mesh cover has a hydrophobic coating on at least one side surface in the first direction. By applying this hydrophobic coating, liquids are less likely to adhere to the surface, allowing them to form droplets and slide off, thus preventing the formation of icicles. Simultaneously, the hydrophobic coating possesses low adhesion properties, which helps snow to slide off automatically under gravity or wind force, reducing manual snow removal and maintenance work.

[0030] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0031] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and 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 of this application.

[0032] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0033] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0035] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0036] See Figure 1 and Figure 2 , Figure 1The diagram shows a structural schematic of a mesh cover according to an embodiment of this application. The mesh cover provided in this embodiment includes a cover body 10, which is the main structure of the mesh cover. The mesh cover can be applied to the ventilation system of outdoor equipment. The ventilation system has ventilation holes. The cover body 10 can cover the air outlet of the main unit to protect the ventilation holes and prevent foreign objects from entering the ventilation system, which would cause the outdoor equipment to malfunction.

[0037] The cover 10 has heat exchange holes 11 extending along the first direction X. These holes 11 are connected to air outlets, allowing airflow from the main unit's outlet to be discharged into the external environment. Furthermore, at least one surface of the cover 10 in the first direction X is coated with a hydrophobic coating. This coating prevents liquids from adhering to the cover, allowing them to form droplets and slide off, thus preventing icicle formation. The hydrophobic coating also exhibits low adhesion, facilitating the automatic sliding of snow by gravity or wind, reducing manual snow removal and maintenance.

[0038] It should be noted that "at least one side" refers to the different locations where water droplets condense on the mesh cover depending on the orientation of the mesh cover. Therefore, depending on the actual usage requirements, a hydrophobic coating can be applied to the surface of the cover 10 on the side where water droplets are easily condensed. Alternatively, a hydrophobic coating can be applied to both sides of the cover 10 in the first direction X, or a hydrophobic coating can be applied to the entire exposed surface of the cover 10.

[0039] In some embodiments of this application, the hydrophobic coating includes fluoride and silicon dioxide. After the cover 10 is manufactured, the charged fluoride-nano silicon dioxide composite material can be deposited onto the surface of the metal cover 10 by electrophoresis and penetrates into the pores and edges of the cover 10 to form a uniform hydrophobic coating without affecting the breathability and protective performance of the cover 10.

[0040] The hydrophobic coating, constructed from a fluoride-nano silica composite, possesses low surface tension, making it difficult for water droplets or snow to adhere to its surface. Instead, water droplets form spherical beads and slide off, or snow layers loosely slide off, effectively reducing water stains and snow accumulation, and lowering the likelihood of residual liquid freezing into ice. Simultaneously, the low surface tension of the hydrophobic coating also prevents contaminants from accumulating on it. When the mesh cover is used in outdoor equipment, rainwater can wash away surface contaminants, enhancing the mesh cover's self-cleaning ability.

[0041] In some embodiments of this application, the cover 10 includes two end portions 12 disposed opposite each other in a third direction Z intersecting the first direction X, and a middle portion 13 located between the two end portions 12, and at least one end portion 12 and the middle portion 13 have a height difference in the first direction X. The middle portion 13 refers to the middle part of the cover 10 in the third direction Z. The middle portion 13 can be the exact center of the cover 10 in the third direction Z, or it can be any other part located between the two end portions 12. The middle portion 13 can be an endpoint, a line, or a plane. Specifically... Figure 1 In one embodiment, the cover 10 is composed of multiple support beams 20 spaced apart along the second direction Y. The middle part 13 is the line connecting the endpoints of all the support beams 20 in the middle of the third direction Z, while the end part 12 is the line connecting the endpoints of all the support beams 20 in the same segment in the third direction Z.

[0042] Furthermore, each end 12 and the middle part 13 have a height difference in the first direction X, thus making the cover 10 have a convex structure in the middle, that is, the cover 10 has an arch shape. In practical applications, the arch-shaped net cover can be used for the drain outlet or ventilation system of outdoor equipment with top air outlet, etc., to ensure smooth airflow while minimizing the accumulation of debris. It is understandable that, depending on the actual installation method of the net cover, only one end 12 and the middle part 13 may have a height difference in the first direction X, but in this case, the cover 10 is also an arched structure.

[0043] Specifically, when installing the net cover, the height of the middle part 13 of the cover body 10 can be higher than the two ends 12, so that when debris falls onto the cover body 10, the debris located on the middle part 13 of the cover body 10 or towards the two ends 12 of the cover body 10 will slide off under the action of gravity or wind, thus preventing debris from accumulating on the cover body 10.

[0044] Furthermore, the synergistic effect of the arch structure and hydrophobic coating makes it difficult for debris to adhere to the mesh surface, allowing it to fall off naturally with rain or wind. Simultaneously, in cold environments, snow easily slides off under gravity or wind, preventing structural damage caused by excessive snow accumulation. This structure significantly reduces the frequency of manual cleaning and improves the stability of equipment operation.

[0045] In some embodiments, the surface between at least one end 12 and the middle portion 13 is smoothly transitioned, so that debris, rainwater and snow on the surface of the cover 10 can more easily slide off the surface of the cover 10, forming a natural drainage and snow removal path, and making it less likely for debris or rain and snow to accumulate.

[0046] In some embodiments, at least one surface between the end 12 and the middle portion 13 is curved, resulting in the entire cover 10 having a semi-elliptical or semi-circular structure; alternatively, the surface between the end 12 and the middle portion 13 may be parabolic. In other embodiments, the surface between the end 12 and the middle portion 13 may be flat, depending on the wind direction and frequency of rain and snow at the actual installation location of the net, in which case the entire net will be V-shaped. In still other embodiments, the surface of the cover 10 may also be flat. It is understood that the shape of the cover 10 can be selected according to actual usage requirements and is not limited here.

[0047] In some embodiments of this application, the cover 10 includes a plurality of support beams 20 spaced apart along the second direction Y. Each support beam 20 extends longitudinally along the third direction Z. The first direction X, the second direction Y, and the third direction Z intersect each other but are not coplanar. Each support beam 20 is a cylinder with a diameter of 2.5 mm, and the distance between two adjacent beams is 20 mm, so that heat exchange holes 11 are formed between two adjacent support beams 20.

[0048] It is understandable that the surface of the cover 10 refers to the surface formed by all the supporting beams 20 on the same side in the first direction X. Depending on the different structures of the cover 10, the supporting beams 20 can be straight or curved. When all the supporting beams 20 are straight, the surface of the cover 10 is planar; when all the supporting beams 20 are curved, the surface of the cover 10 forms a planar surface. Figure 1 The arched structure shown.

[0049] In some embodiments, see Figure 1 To improve the overall structural strength of the enclosure 10, the enclosure 10 also includes fixed beams 21. Each fixed beam 21 extends longitudinally along the second direction Y and is connected to each support beam 20. The fixed beams 21 can be connected to the support beams 20 by welding or integral molding, thus connecting all the support beams 20 into a single unit and improving the structural strength of the enclosure 10. Optionally, the fixed beams 21 are cylinders with a diameter of 2.5 mm, and multiple fixed beams 21 are arranged at intervals along the third direction Z. This strengthens the structure of the enclosure 10 and also reduces the size of the heat exchange holes 11, preventing users from directly contacting the internal structure of the enclosure.

[0050] In some embodiments, the fixed beam 21 further includes two assembled beams 22, which are spaced apart along the third direction Z, and each of the support beams 20 is connected to the two assembled beams 22 at both ends of the third direction Z.

[0051] In some embodiments, see Figure 3 and Figure 4 The fixed beam 21 also includes two assembly beams 22, which are spaced apart along the third direction Z. Each support beam 20 is connected to the two assembly beams 22 at both ends in the third direction Z. Each assembly beam 22 has a mounting hole 30 at at least one end in the second direction Y. The assembly beams 22, like the fixed beam 21, not only fix the multiple support beams 20 to improve the overall structural strength of the cover 10, but also, through the four mounting holes 30 on the two assembly beams 22, fix the entire cover 10 formed by the support beams 20, fixed beams 21, and assembly beams 22 to outdoor equipment or other mounting foundations.

[0052] Specifically, in some embodiments, see [link to relevant documentation]. Figure 5 and Figure 6 The mesh cover also includes two crossbeams 23, which are spaced apart along the second direction Y. Each assembled beam 22 is positioned between the two crossbeams 23 at both ends in the second direction Y. Each crossbeam 23 has two fixing holes spaced apart along the third direction Z, and each fixing hole is aligned with one of the mounting holes 30. That is, the four fixing holes on the two crossbeams 23 are aligned with the four mounting holes 30 on the two fixing beams 21. Furthermore, the mesh cover also includes fasteners such as bolts, which pass through the fixing holes and mounting holes 30, thereby fixing the assembled beams 22 to the crossbeams 23.

[0053] The fixing of the crossbeam 23 to the assembly beam 22 not only increases the structural strength of the entire mesh enclosure but also improves the flexibility of its assembly. In practical use, different mounting structures can be installed on the crossbeam 23 to allow it to be fixed to outdoor equipment or other mounting foundations. Specifically… Figure 5 and Figure 6 In one embodiment, the crossbeam 23 is also provided with assembly holes 32 at both ends in the third direction Z. The assembly holes 32 can be used with fasteners such as bolts to fix the crossbeam 23 to outdoor equipment or other installation foundations.

[0054] Furthermore, in order to facilitate the alignment of the mounting hole 30 and the fixing hole, a positioning groove 31 is provided on the crossbeam 23, and the fixing hole is located at the bottom of the positioning groove 31. The end 12 of the assembly beam 22 in the second direction Y can extend into the positioning groove 31 so as to quickly position the assembly beam 22 through the positioning groove 31, thereby facilitating the alignment of the fixing hole and the mounting hole 30.

[0055] In some embodiments of this application, the cover 10 further includes two reinforcing beams 24, the diameter of which is larger than that of the support beams 20. The two reinforcing beams 24 are spaced apart along the second direction Y, and all the support beams 20 are located between the two reinforcing beams 24. Each reinforcing beam 24 is connected to two assembly beams 22 at both ends in the third direction Z. Since the diameter of the reinforcing beams 24 is larger than that of the support beams 20, it can improve the overall structural strength of the cover 10 compared to the support beams 20. Furthermore, since the reinforcing beams 24 are located on both sides of the cover 10, their excessively large diameter can prevent them from affecting the size of the heat exchange holes 11. Optionally, the diameter of the reinforcing beams 24 is 6 mm.

[0056] In some embodiments of this application, the cover 10 further includes side beams 25, at least one reinforcing beam 24 extending longitudinally along a curve, and the side beams 25 extending longitudinally in the third direction Z. The two ends of the side beams 25 are connected to the reinforcing beams 24 respectively, so as to supplement the strength of the curved reinforcing beams 24 through the side beams 25. Specifically, each reinforcing beam 24 and each supporting beam 20 extend longitudinally along an arc, so that a height difference is formed between the end 12 and the middle 13 of the cover 10, ultimately forming an arched cover 10. The side beams 25 can strengthen the structure of the arched cover 10, improving the structural strength of the entire mesh cover.

[0057] This application also provides an outdoor device that includes a mesh cover as described in any of the above embodiments. Optionally, the outdoor device is an outdoor unit of an air conditioner. Since the outdoor device includes all the technical features of the aforementioned mesh cover, it possesses all the technical effects of the aforementioned mesh cover, which will not be elaborated further here.

[0058] The aforementioned mesh cover has at least the following advantages:

[0059] The cover 10 has a hydrophobic coating on at least one side surface in the first direction X. By applying the hydrophobic coating to the surface of the cover 10, liquids are less likely to adhere to its surface, allowing liquids to form droplets and slide off the surface of the cover 10, thus preventing the formation of icicles. At the same time, the hydrophobic coating has a certain degree of low adhesion, which helps snow to slide off automatically under the action of gravity or wind, reducing manual snow removal and maintenance work.

[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
