Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to a fresh air rainproof cover and an air conditioner. Background Technology

[0002] The air intake end of an air conditioning unit's fresh air duct is usually located outdoors and needs to be equipped with a rain cover to prevent rainwater from entering the duct. These rain covers typically have a grille structure, which provides some protection against insects and dust.

[0003] Currently, rain covers on the market are usually of an integrated structure, relying on ultrasonic welding technology to weld the cover and grille into a whole, which is difficult to operate and has a high production cost. Summary of the Invention

[0004] The problem solved by this invention is that existing fresh air rainproof covers are difficult to produce and have high production costs.

[0005] To address the aforementioned problems, this invention provides a new type of rainproof cover that is easy to manufacture and has lower costs.

[0006] An embodiment of the present invention provides a fresh air rainproof cover, including a cover shell and a grille. The cover shell has an air inlet. One of the grille and the cover shell is provided with an elastic buckle, and the other one is provided with a locking hole. The grille covers the air inlet, and the elastic buckle engages with the locking hole.

[0007] The new air rain cover provided in this embodiment of the invention uses a snap-fit ​​mechanism between the grille and the cover shell, replacing the ultrasonic welding process of existing rain covers, which greatly reduces the difficulty of production and assembly and lowers production costs.

[0008] In an optional embodiment, the elastic buckle is disposed on the grille, and the snap hole is disposed through the side wall of the air inlet.

[0009] In an optional embodiment, the elastic buckle extends into the air inlet and engages with the locking hole.

[0010] The elastic buckle extends into the air inlet and engages with the locking hole. The cover protects the buckle, preventing it from being exposed to the environment and extending the service life of the rain cover.

[0011] In an optional embodiment, a groove is recessed on the inner sidewall of the air inlet, the groove extending from the end wall of the air inlet to the locking hole, and the groove is used to guide the elastic buckle to slide.

[0012] The inner wall of the air inlet is recessed with a groove that extends to the locking hole. In practical applications, when the grille is placed on the air inlet of the cover, the buckle can slide along the groove to the locking hole to achieve quick positioning and further reduce the difficulty of installation.

[0013] In an optional embodiment, a reinforcing protrusion is provided on the outer wall of the air inlet corresponding to the position of the locking hole, and the locking hole extends through the reinforcing protrusion.

[0014] The reinforcing protrusions strengthen the structure of the snap-fit ​​joint, prevent water from flowing into the snap hole from the outer wall of the cover, and extend the length of the snap hole to prevent it from protruding and being exposed, thus providing further protection for the snap-fit.

[0015] In an optional embodiment, the end wall of the air inlet is recessed with a receiving annular groove, the receiving annular groove is connected to the inner side wall of the air inlet, and the grille is at least partially embedded in the receiving annular groove.

[0016] During assembly, the buckle extends from the air inlet into the housing and engages with the buckle hole. Simultaneously, the grille extends into the air inlet and embeds into the storage ring groove. The grille serves to catch water dripping from the outer wall of the air inlet of the housing, guiding the water on the housing to flow smoothly down and preventing water on the outer wall of the housing from entering the fresh air duct through the air inlet.

[0017] In an optional embodiment, the grille is hemispherical, and the grille is provided with a bottom end and a top end, and the radius of the cross-section of the grille gradually decreases from the bottom end to the top end.

[0018] The grille is hemispherical, with its bottom end covering the air inlet of the enclosure. Water dripping from the outer wall of the air inlet can flow smoothly along the curved outer wall of the grille to the top and then drip off smoothly, avoiding water accumulation on the grille and reducing the risk of water being sucked into the fresh air duct.

[0019] In an optional embodiment, the grid is provided with a plurality of horizontal ribs and a plurality of vertical ribs in an alternating manner. The plurality of horizontal ribs are distributed at intervals from the bottom end to the top end, and one end of each of the plurality of vertical ribs is evenly distributed at intervals in the circumferential direction at the bottom end, and the other end of each of them converges at the top end.

[0020] Multiple longitudinal ribs are evenly spaced at one end around the bottom circumference, and their other ends converge at the top, serving to guide the water flowing from the outer wall of the air inlet to the top of the grille, directing this water to flow down quickly and preventing it from accumulating at the air inlet. Furthermore, the multiple grille openings formed by the evenly distributed longitudinal and transverse ribs achieve uniform air intake in multiple directions.

[0021] In an optional embodiment, the elastic buckle protrudes from the end wall of the bottom end, and the bottom end extends into the air inlet.

[0022] An embodiment of the present invention also provides an air conditioner, including the aforementioned fresh air rainproof cover. The fresh air rainproof cover includes a cover shell and a grille. An air inlet is provided on the cover shell. One of the grille and the cover shell is provided with an elastic buckle, and the other one is provided with a locking hole. The grille covers the air inlet, and the elastic buckle engages with the locking hole. Attached Figure Description

Detailed Implementation

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Please see Figure 1 , Figure 2 and Figure 3 , Figure 1 The diagram shown is a structural schematic of a fresh air rain cover 100 provided in this embodiment. Figure 2 The diagram shown is a structural schematic of the casing. Figure 3 The diagram shown is a structural schematic of the grille.

[0031] The fresh air rain cover 100 provided in this embodiment is applied to an air conditioner and installed at the outdoor end of the fresh air duct of the air conditioner. It is used to introduce outdoor fresh air while preventing rainwater and insects from entering the fresh air duct.

[0032] The fresh air rain cover 100 provided in this embodiment includes a cover 110 and a grille 130. The cover 110 has an air inlet 111 and a connecting joint 113 for connecting the fresh air duct. The air inlet 111 is connected to the connecting joint 113 through the inside of the cover 110, and is used to introduce outdoor air into the fresh air duct.

[0033] The grille 130 is equipped with a flexible buckle 131, and the cover 110 is equipped with a locking hole 115. The grille 130 is engaged with the locking hole 115 on the cover 110 via the flexible buckle 131, thereby sealing the air inlet 111 and achieving an insect-proof effect. Understandably, in practical applications, the air inlet 111 of the cover 110 points towards the ground to prevent rainwater from entering.

[0034] In other embodiments, the positions of the elastic buckle 131 and the buckle hole 115 can be interchanged, that is, the buckle hole 115 is provided on the grille 130 and the elastic buckle 131 is provided on the cover 110.

[0035] Furthermore, in other embodiments, other snap-fit ​​structures can be used. For example, hooks are provided on both the cover 110 and the grille 130, and the two hooks hold each other to achieve the installation and fixation of the grille 130 on the cover 110.

[0036] In the actual production and assembly process, the operator can quickly install the grille 130 by snapping the elastic buckle 131 on the grille 130 into the corresponding buckle hole 115 on the cover 110. Compared with the ultrasonic welding process used in the existing rain cover, the operation is more convenient and faster, and saves production costs.

[0037] Furthermore, the grille 130 and the cover 110 are fastened together, so that if the grille 130 is damaged by weathering as the usage time increases, a new grille 130 can be easily and quickly replaced, thus avoiding the scrapping of the entire fresh air rain cover 100.

[0038] Considering that the lifespan of the buckle will be shortened rapidly when it is exposed to wind and sun in the outdoor environment, in this embodiment, the elastic buckle 131 extends into the air inlet 111 and engages with the buckle hole 115.

[0039] The elastic buckle 131 extends into the air inlet 111 and engages with the buckle hole 115 provided on the side wall of the air inlet 111. That is, the elastic buckle 131 is protected by the cover 110, avoiding direct sunlight and wind and rain, thus greatly extending its service life.

[0040] In order to achieve precise alignment between the elastic buckle 131 and the locking hole 115 and further simplify the installation operation, in this embodiment, a locking groove 117 is recessed on the inner side wall of the air inlet 111. The locking groove 117 extends from the end wall of the air inlet 111 to the locking hole 115 and is used to guide the elastic buckle 131 to slide.

[0041] In practical applications, during the process of covering the air inlet 111 with the grille 130, the elastic buckle 131 is aligned with one end of the end wall of the air inlet 111 connected to the slot 117, so that the elastic buckle 131 extends into the slot 117 and gradually slides into the cover 110 along the slot 117. During this process, the size is preset to ensure that the elastic buckle 131 undergoes elastic deformation due to the force of the bottom wall of the slot 117. When the elastic buckle 131 slides along the slot 117 to the locking hole 115, the elastic buckle 131 releases its elastic potential energy, the elastic buckle 131 locks into the locking hole 115, the elastic deformation is restored, and the installation of the grille 130 on the cover 110 is completed.

[0042] When the grille 130 needs to be disassembled for replacement, the elastic buckle 131 is applied to the end of the clip hole 115 on the outer side wall of the cover 110 with a force pointing inward to the cover 110, and at the same time the grille 130 is pulled in the direction of exiting the air inlet 111. When the elastic buckle 131 exits the clip hole 115, it loses the limiting effect of the clip hole 115, and exits the air inlet 111 along the clip groove 117 under the action of the grille 130, thereby completing the disassembly of the grille 130.

[0043] Furthermore, considering that the structural strength is low at the location where the card hole 115 is opened on the cover 110, in this embodiment, a reinforcing protrusion 118 is provided on the outer side wall of the air inlet 111 on the cover 110 at the location corresponding to the card hole 115, and the card hole 115 extends through the reinforcing protrusion 118.

[0044] The reinforcing protrusion 118 strengthens the structural strength of the locking hole 115, ensuring the reliability of the locking structure between the elastic buckle 131 and the locking hole 115. Furthermore, the reinforcing protrusion 118 extends the locking hole 115, preventing the elastic buckle 131 from protruding from the locking hole 115 and being exposed to the external environment due to the locking hole 115 being too short.

[0045] Additionally, considering that in practical applications, rainwater will flow down the outer wall of the housing 110 to the air inlet 111, to prevent rainwater from accumulating at the end wall of the air inlet 111 and being drawn into the fresh air duct, please refer to [further details needed]. Figure 2 In this embodiment, a receiving annular groove 119 is recessed on the end wall of the air inlet 111. The receiving annular groove 119 is connected to the inner side wall of the air inlet 111, and the grille 130 is at least partially embedded in the receiving annular groove 119.

[0046] In this embodiment, the grille 130 is plate-shaped, and the elastic buckle 131 protrudes from one side edge of the grille 130. When the elastic buckle 131 is engaged, the grille 130 is completely embedded in the receiving annular groove 119, that is, the side of the grille 130 away from the elastic buckle 131 is flush with the end wall of the air inlet 111. The grille 130 being embedded in the receiving annular groove 119 is equivalent to providing a certain degree of sealing for the periphery of the air inlet 111, which can greatly prevent rainwater from accumulating on the end wall of the air inlet 111.

[0047] To further prevent rainwater backflow, this embodiment also provides another fresh air rain cover 100, please refer to [link / reference needed]. Figure 4 , Figure 4 The diagram shown is a structural schematic of another fresh air rain cover 100 provided in this embodiment.

[0048] The grille 130 of the new air rain cover 100 is hemispherical, that is, the grille 130 is provided with a bottom end 133 and a top end 135 respectively, and the radius of the cross-section of the grille 130 gradually decreases from the bottom end 133 to the top end 135.

[0049] The elastic buckle 131 protrudes from the end wall of the bottom end 133. The elastic buckle 131 extends into the air inlet 111 through the slot 117 and engages with the slot 115. The bottom end 133 is embedded in the receiving ring groove 119. It can be seen that, since the end wall of the bottom end 133 is embedded in the receiving ring groove 119, the outer wall of the bottom end 133 is connected to the end wall of the air inlet 111.

[0050] In practical applications, when rainwater on the outer wall of the air inlet 111 flows to the end wall of the air inlet 111, under the receiving and guiding effect of the outer wall of the bottom end 133 of the grille 130, the rainwater can smoothly slide down along the curved outer surface of the grille 130, causing the rainwater to flow quickly to the top end 135 of the grille 130 and then drip down quickly.

[0051] The grille 130 is provided with a plurality of horizontal ribs 137 and a plurality of vertical ribs 139 interlaced. The plurality of horizontal ribs 137 are distributed at intervals from the bottom end 133 to the top end 135. One end of each of the plurality of vertical ribs 139 is evenly distributed at intervals around the bottom end 133, and the other end of each of them converges at the top end 135.

[0052] Multiple longitudinal ribs 139 serve to guide rainwater. Since these ribs extend from the bottom 133 to the top 135 and converge there, in practical applications, rainwater flowing from the end wall of the air inlet 111 to the bottom 133 is rapidly directed downwards by the ribs 139, and converges at the top 135, forming larger water droplets. These droplets then easily drip off the top 135 under gravity. Furthermore, the uniform distribution of the ribs 139 ensures even upward airflow around the grille 130, thereby increasing the air intake volume.

[0053] It is understood that in this embodiment, the hemispherical grille 130 is not strictly a hemisphere, but rather a structure with an outer wall that is curved, corresponding to the shape of the air inlet 111. For example, when the air inlet 111 is rectangular, the grille 130 can be a square pyramid structure.

[0054] In summary, the fresh air rain cover 100 provided in this embodiment achieves the snap-fit ​​between the grille 130 and the cover 110 by setting elastic buckles 131 on the grille 130 and corresponding snap holes 115 on the cover 110 for snapping the elastic buckles 131. Compared with the existing rain cover which uses ultrasonic welding, it has the advantages of being more convenient to operate and lower in cost.

[0055] Furthermore, the elastic buckle 131 extends into the inside of the cover 110 and engages with the buckle hole 115, thus protecting the elastic buckle 131 from direct sunlight and wind and rain, and greatly extending its service life.

[0056] In addition, the grille 130 is embedded in the receiving ring groove 119, which plays a certain role in sealing the inner wall and end wall of the air inlet 111. The grille 130 also plays a role in receiving and guiding rainwater on the end wall of the air inlet 111, preventing rainwater from accumulating on the end wall of the air inlet 111, thereby preventing rainwater from being sucked into the fresh air duct through the air inlet 111.

[0057] Therefore, the fresh air rain cover 100 provided in this embodiment has the characteristics of being easier to process, having lower production costs, longer service life, and better water absorption resistance.

[0058] This embodiment also provides an air conditioner, including the aforementioned fresh air rain cover 100. A connecting joint 113 on the cover 110 of the fresh air rain cover 100 connects to the outdoor end of the air conditioner's fresh air duct, guiding outdoor fresh air into the duct while preventing rain and insects from entering. Therefore, the air conditioner provided in this embodiment has the advantages of easier processing, lower production costs, longer service life, and better water absorption resistance.

[0059] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
