[0045] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0046] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0047] The air conditioner 100 of this utility model is described below with reference to the accompanying drawings.

[0048] According to the embodiment of the present utility model, the air conditioner 100, such as Figures 1-3 As shown, the air conditioner 100 includes: an air conditioner body 1, an air outlet grille 2, and a locking member 3. The air conditioner body 1 has an air outlet 11. The air outlet grille 2 covers the air outlet 11 and is detachably connected to the air conditioner body 1. The locking member 3 locks the relative position of the air outlet grille 2 and the air conditioner body 1 in the locked state. The locking member 3 has an unlocking part 3a, so that the locking state of the locking member 3 can be released by operating the unlocking part 3a with a tool, making the air outlet grille 2 detachable relative to the air conditioner body 1.

[0049] The air conditioner body 1 is provided with an air outlet 11, and an air outlet grille 2 is provided on the air outlet 11. The air outlet grille 2 not only serves as an external component of the air conditioner 100, but also guides the airflow from the air outlet 11 and has a ducting function. The air outlet grille 2 is detachably connected to the air conditioner body 1, and can be removed from the air conditioner body 1 for cleaning. This reduces the accumulation of dust on the air outlet grille 2 and helps improve the airflow performance of the air conditioner 100.

[0050] In related technologies, the connection between the air outlet grille and the air conditioner body does not meet the requirements. A protective net needs to be installed at the air outlet to isolate the impeller and other components inside the air outlet from the outside, so as to meet the requirement of preventing hands from touching the impeller. This results in an increase in assembly steps and manufacturing costs.

[0051] Therefore, this utility model also includes a locking component 3. When locked, the locking component 3 locks the relative position of the air outlet grille 2 and the air conditioner body 1. When the locking component 3 is locked, it cannot be unlocked by hand, and therefore the air outlet grille 2 cannot be removed from the air conditioner body 1 by hand. Only after unlocking the locking component 3 with the help of a tool can the operation of removing the air outlet grille 2 from the air conditioner body 1 be carried out.

[0052] Because the locking element 3 locks the relative position of the air outlet grille 2 and the air conditioner body 1, the connection effect of the locking element 3 is more stable. At this time, the air outlet grille 2 and the air conditioner body 1 are fixed as a whole. Disassembly of the air outlet grille 2 and the air conditioner body 1 requires the use of tools. Therefore, the air outlet grille 2 set at the air outlet 11 plays the role of isolating the impeller and other components inside the air outlet 11 from the outside. Users cannot directly touch the impeller inside the air conditioner body 1 from the air outlet 11 after disassembly by hand, which meets the requirement of preventing hand contact with the impeller. Thus, the protective net can be eliminated, the disassembly and assembly process can be reduced, the assembly efficiency of the air conditioner 100 can be improved, and manufacturing costs can be saved. In addition, eliminating the obstruction of the protective net at the air outlet 11 also helps to reduce the wind resistance of the air outlet 11 and increase the air volume.

[0053] It is worth noting that after the locking device 3 is released, the air outlet grille 2 and the air conditioner body 1 can remain relatively stationary or move relative to each other. Alternatively, after the locking device 3 is released, the air outlet grille 2 and the air conditioner body 1 can be switched to a state where they can be disassembled by hand. At this time, the user can disassemble and assemble the air outlet grille 2 and the air conditioner body 1 without the aid of tools, which facilitates the cleaning of the air outlet grille 2, reduces the dust accumulated on the air outlet grille 2, and helps improve the air outlet effect of the air conditioner 100.

[0054] According to the embodiment of the present utility model, the air conditioner 100, by setting the locking member 3, requires the use of tools to disassemble the air outlet grille 2 from the air conditioner body 1, which meets the requirement of preventing hands from touching the fan wheel, thereby eliminating the need for the protective net, reducing assembly steps, improving the overall assembly efficiency of the air conditioner 100, saving manufacturing costs, and also helping to increase the air volume.

[0055] In some embodiments of this utility model, the air outlet grille is located at the air outlet position, and the air outlet grille is constructed of heat-resistant materials such as ABS (Acrylonitrile Butadiene Styrene copolymer) or PC (Polycarbonate).

[0056] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the locking element 3 is constructed as a limiting pin 31, which passes through the air outlet grille 2 and the air conditioner body 1, and is interference-fitted with at least one of the air outlet grille 2 and the air conditioner body 1.

[0057] The locking component 3 is constructed as a limiting pin 31. The limiting pin 31 passes through the air outlet grille 2 and the air conditioner body 1. When it is in an interference fit with at least one of the air outlet grille 2 and the air conditioner body 1, the connection between the air outlet grille 2 and the air conditioner body 1 is locked. At this time, a tool is needed to release the interference fit between the limiting pin 31 and the air outlet grille 2 and / or the air conditioner body 1 in order to unlock the locked state of the limiting pin 31 and then the air outlet grille 2 can be removed from the air conditioner body 1.

[0058] By using a limiting pin 31 to pass through the air outlet grille 2 and the air conditioner body 1, the openings on the air outlet grille 2 and the air conditioner body 1 are simple, which can reduce the manufacturing difficulty compared to using threaded fasteners to connect the air outlet grille or the air conditioner body with threads.

[0059] In some embodiments of this utility model, such as Figure 4 and Figure 6 As shown, the limiting pin 31 has an interference fit with one of the air outlet grille 2 and the air conditioner body 1, and a clearance fit with the other. When the tool releases the locked state of the limiting pin 31, it is only necessary to release the interference fit between the limiting pin 31 and one of the air outlet grille 2 and the air conditioner body 1, which simplifies the operation steps, reduces the difficulty of unlocking the locking state of the locking component 3, and facilitates the disassembly of the air outlet grille 2.

[0060] In some specific embodiments of this utility model, such as Figure 5 and Figure 6 As shown, the air outlet grille 2 is installed on the front side of the air conditioner body 1. The limiting pin 31 passes through the air outlet grille 2 and the air conditioner body 1 from front to back. The limiting pin 31 is interference-fitted with the air outlet grille 2 and clearance-fitted with the air conditioner body 1.

[0061] By interfering with the limit pin 31 and the air outlet grille 2, the interfering part of the limit pin 31 and the air outlet grille 2 is closer to the outer side than the mating part of the air conditioner body 1, and is less obstructed, providing more operating space and making it easier to use tools to unlock the locking part 3, thus reducing the difficulty of operation.

[0062] In some embodiments of this utility model, the interference fit between the limiting pin 31 and one of the air outlet grille 2 and the air conditioner body 1 is 1-3mm, which is an interference fit to prevent it from falling off; the clearance fit between the limiting pin 31 and the other of the air outlet grille 2 and the air conditioner body 1 is 0-2mm, which is a clearance fit to facilitate assembly and at the same time achieve the limiting function to prevent it from falling off.

[0063] Optionally, the interference fit of the limit pin 31 is 1mm, 1.5mm, 2mm, 2.5mm, 3mm, etc.

[0064] Optionally, the clearance fit of the limit pin 31 is 0.1mm, 0.5mm, 1mm, 1.8mm, 2mm, etc.

[0065] In some embodiments of this utility model, such as Figure 2 and Figure 4 As shown, the air conditioner body 1 includes a first mating part 12 located inside the air outlet grille 2, and the air outlet grille 2 includes a second mating part 23 located outside the first mating part 12, as shown. Figure 3 and Figure 5 As shown, the second mating part 23 has a second mating hole 231 that extends through in the inward and outward directions, and the first mating part 12 has a first mating hole 121 that is open at least on the outer side. The limiting pin 31 passes through the second mating hole 231 and the first mating hole 121 in sequence from the outside to the inside.

[0066] The air conditioner body 1 includes a first mating part 12 located inside the air outlet grille 2, and the air outlet grille 2 includes a second mating part 23 located outside the first mating part 12. Here, the inward and outward directions are with the air conditioner 100 as the reference system. The limiting pin 31 passes through the second mating part 23 of the air outlet grille 2 and the first mating part 12 of the air conditioner body 1 in sequence from the outside of the air conditioner 100 to the inside.

[0067] The second mating part 23 has a second mating hole 231 that extends in the inward and outward directions, allowing the limiting pin 31 to pass through the second mating part 23. The first mating part 12 on the first mating part 12 can be a through hole or a blind hole that opens outwards, allowing the limiting pin 31 to be inserted into the first mating part 12. At least one of the first mating hole 121 and the second mating hole 231 of the limiting pin 31 is in an interference fit.

[0068] In some embodiments of this utility model, such as Figure 3 As shown, the unlocking part 3a is formed as a tool hole 311 and penetrates the side wall of the limiting pin 31, and the second mating part 23 has a tool clearance opening 241 that is disposed opposite to the tool hole 311.

[0069] When the tool unlocks the locked state of the limit pin 31, it can be inserted through the tool clearance port 241 to contact the limit pin 31. The second mating part 23 is located outside the first mating part 12. Therefore, the tool clearance port 241 is provided on the second mating part 23 to avoid the operation path of the tool, provide operable space, and reduce the difficulty of operation.

[0070] Furthermore, the tool clearance opening 241 is directly opposite the tool hole 311. A tool inserted through the tool clearance opening 241 can smoothly enter the tool hole 311, thereby contacting the interior of the limiting pin 31. The tool cooperates to release the interference fit with the first mating hole 121 and / or the second mating hole 231, thereby releasing the locking state of the locking member 3. For example, when the tool is inserted into the tool hole 311, the tool can abut against the inner wall surface of the limiting pin 31, driving the limiting pin 31 to move outward to release the interference fit with the first mating hole 121 and / or the second mating hole 231, thereby releasing the locking state of the locking member 3.

[0071] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the two ends of the air outlet grille 2 along its length are the first end 21 and the second end 22, respectively. The second mating part 23 is provided at the second end 22. The tool hole 311 is open in a direction away from the first end 21. The tool clearance opening 241 is located on the side of the tool hole 311 away from the first end 21.

[0072] The two ends of the air outlet grille 2 along its length are the first end 21 and the second end 22, respectively. Therefore, the space between the first end 21 and the second end 22 is the main body of the air outlet grille 2. By opening the tool hole 311 in a direction away from the first end 21, the interference between the tool and the air outlet grille 2 during use can be reduced, making it easier to operate.

[0073] In some embodiments of this utility model, such as Figure 2 As shown, the first end 21 is the upper end of the air outlet grille 2, the second end 22 is the lower end of the air outlet grille 2, the second mating part 23 is provided at the second end 22, and the locking member 3 connects the lower end of the air outlet grille 2 and the lower end of the air conditioner body 1. The operating height is low, which makes it easy to operate.

[0074] like Figure 3 and Figure 6 As shown, the tool hole 311 is open downwards, and the tool clearance opening 241 is located below the tool hole 311, which can reduce the contact of water droplets and other contaminants with the limit pin 31 and can protect the limit pin 31.

[0075] In some embodiments of this utility model, such as Figure 3 As shown, the second mating hole 231 is constructed as a polygonal hole, and the limiting pin 31 includes a polygonal portion 312 that mates with the second mating hole 231, and the polygonal portion 312 mates within the polygonal hole.

[0076] The polygonal portion 312 of the limiting pin 31 cooperates with the polygonal hole to restrict the rotation of the limiting pin 31 relative to the second mating portion 23, thereby making the installation stability of the limiting pin 31 stronger and ensuring that the tool hole 311 of the limiting pin 31 and the tool clearance hole are aligned.

[0077] The following is a reference appendix. Figures 3-6 This invention describes the process of locking and unlocking the limiting pin 31 according to a specific embodiment of the present invention.

[0078] The air conditioner body 1 includes a first mating part 12 located inside the air outlet grille 2, and the air outlet grille 2 includes a second mating part 23 located outside the first mating part 12. The second mating part 23 has a second mating hole 231 that extends in the inward and outward directions. The first mating part 12 has a first mating hole 121 that is open at least on the outer side. The limiting pin 31 is interference-fitted with the second mating hole 231, and the limiting pin 31 is clearance-fitted with the first mating hole 121. The mating of the limiting pin 31 and the second mating hole 231 is located on the outer side, with less obstruction, providing a larger operating space, making it easier to use tools to unlock the locking member 3, and reducing the difficulty of operation.

[0079] like Figure 3 As shown, a mounting platform 24 protruding outward is formed on the second mating part 23. A second mating hole 231 is formed on the mounting platform 24. A cavity is formed inside the mounting platform 24, which communicates with the second mating hole 231 located on the rear side. A tool clearance opening 241 communicating with the cavity is formed on the side of the mounting platform 24 away from the first end 21. An installation clearance opening 242 is formed on the end face of the mounting platform 24 facing outward. The limiting pin 31 passes through the second mating part 23 from front to back, is inserted through the installation clearance opening 242 of the mounting platform 24, passes through the internal cavity of the mounting platform 24, and then mates with the second mating hole 231.

[0080] like Figure 3 As shown, the limiting pin 31 includes a capping portion 313, a polygonal portion 312, and a cylindrical portion 314 arranged sequentially along the axial direction. The second mating hole 231 is constructed as a polygonal hole, and the polygonal portion 312 of the limiting pin 31 is interference-fitted with the polygonal hole. The first mating hole 121 is constructed as a round hole, and the cylindrical portion 314 of the limiting pin 31 is inserted into the round hole.

[0081] like Figure 3 and Figure 5As shown, the mounting clearance opening 242 is a polygonal hole, and the cross-sectional shape of the cover part 313 is a polygon with the same shape as the mounting clearance opening 242. The cover part 313 is embedded in the mounting clearance opening 242 and makes the outer end face of the limiting pin 31 flush with the outer end face of the mounting platform 24, which can improve the installation stability of the limiting pin 31. Furthermore, the outline of the limiting pin 31 and the air outlet grille 2 is not easily visible from the outside, which can improve the overall integrity of the air outlet grille 2.

[0082] like Figure 5 As shown, the polygonal portion 312 not only has an interference fit with the second mating hole 231, but a portion of the polygonal portion 312 is also located within the cavity of the mounting platform 24. The polygonal portion 312 contacts and has an interference fit with the mounting platform 24, which can improve the stability of the fit between the limit pin 31 and the air outlet grille 2. Figure 5 As shown, the limiting pin 31 has at least one outwardly protruding mating rib 315 on the polygonal portion 312. The mating rib 315 contacts and engages with the inner wall of the mounting platform 24, which can improve the stability of the engagement between the limiting pin 31 and the air outlet grille 2.

[0083] like Figure 3 As shown, the unlocking part 3a is formed as a tool hole 311 and penetrates the side wall of the polygonal part 312 away from the first end 21. The tool hole 311 is directly opposite to the tool clearance opening 241 on the mounting table 24. The tool extends into the tool clearance opening 204 and enters the tool hole 311. The tool can abut against the inner wall surface of the limiting pin 31 away from the first mating part 12, thereby driving the limiting pin 31 to move outward to release the interference fit with the second mating hole 231, thereby releasing the locking state of the locking member 3.

[0084] In some embodiments of this utility model, the locking member 3 is constructed as a threaded fastener, which includes a head and a rod. The rod passes through the air outlet grille 2 and the air conditioner body 1, and is in clearance fit with one of the air outlet grille 2 and the air conditioner body 1, and in thread fit with the other. The head is located on the outside of the rod, and the unlocking part 3a is formed on the head.

[0085] When a threaded fastener passes through the air outlet grille 2 and the air conditioner body 1, and engages with one of the threads of the air outlet grille 2 or the air conditioner body 1, the connection between the air outlet grille 2 and the air conditioner body 1 is locked. At this time, a tool is needed to release the threaded fastener from the thread engagement of the air outlet grille 2 or the air conditioner body 1 in order to unlock the locked state of the threaded fastener and then remove the air outlet grille 2 from the air conditioner body 1.

[0086] The threaded fastener has strong connection stability, and the unlocking part 3a is formed on the head, making it relatively simple to unlock the threaded fastener using tools.

[0087] In some embodiments of this utility model, such as Figure 8and Figure 9 As shown, the air outlet grille 2 is connected to the air conditioner body 1 by a quick-release structure 5 to limit the relative position of the air outlet grille 2 and the air conditioner body. The quick-release structure 5 is configured to allow the air outlet grille 2 to be manually removed from the air conditioner body 1 when the locking member 3 is released.

[0088] The quick-release structure 5 can include the mating structure of the pin 25 and the socket 13 described below, or the mating structure of the third mating part 28 and the fourth mating part 161, or the mating structure of the elastic arm 14 and the supporting part 26, etc.

[0089] The connection between the air outlet grille 2 and the air conditioner body 1 via the quick-release mechanism 5 means that the user can connect the air outlet grille 2 to the air conditioner body 1 without tools using the quick-release mechanism 5, and the user can also remove the air outlet grille 2 from the air conditioner body 1 by touching the connection of the quick-release mechanism 5 without tools. This makes the installation and removal of the air outlet grille 2 simpler, facilitates cleaning of the air outlet grille 2, reduces dust accumulation on the air outlet grille 2, and helps improve the airflow performance of the air conditioner 100.

[0090] When the locking component 3 is in the locked state, it cannot be unlocked by hand, and therefore the air vent grille 2 cannot be removed from the air conditioner body 1 by hand. Only after unlocking the locking component 3 with the help of a tool, so that the air vent grille 2 and the air conditioner body 1 are restored to a state where they can be detached by hand, can the quick-release mechanism 5 be driven by hand to remove the air vent grille 2 from the air conditioner body 1.

[0091] By setting a locking component 3, the air outlet grille 2 can be disassembled and reassembled from the air conditioner body 1 by hand after the locking component 3 is unlocked with a tool, which facilitates the cleaning of the air outlet grille 2. Furthermore, since the disassembly of the air outlet grille 2 from the air conditioner body 1 requires the use of tools, the requirement of preventing hand contact with the fan wheel is met, thereby eliminating the need for a protective net, reducing assembly steps, improving the overall assembly efficiency of the air conditioner 100, saving manufacturing costs, and also helping to increase airflow.

[0092] In some embodiments of this utility model, such as Figure 7 and Figure 8 As shown, the two ends of the air outlet grille 2 along its length are a first end 21 and a second end 22, respectively. The air outlet grille 2 moves along the direction from the second end 22 to the first end 21 so that the first end 21 can be inserted into the air conditioner body 1, as shown. Figure 2 and Figure 6 As shown, the locking member 3 is inserted through the second end 22 and the air conditioner body 1 in the inward and outward directions of the air outlet grille 2 to present a locked state, so as to restrict the movement of the air outlet grille 2 in the direction from the first end 21 to the second end 22 so that the first end 21 is disengaged from the air conditioner body 1.

[0093] By inserting the locking member 3 through the second end 22, the first end 21 of the air outlet grille 2 that cooperates with the air conditioner body 1, and both ends of the length of the air outlet grille 2 that cooperate with the air conditioner body 1, the installation stability of the air outlet grille 2 can be improved.

[0094] In some embodiments of this utility model, the user can move the air outlet grille 2 along the direction from the second end 22 to the first end 21 without the aid of tools so that the first end 21 is inserted into the air conditioner body 1. After the insertion is completed, the air outlet grille 2 is assembled and connected to the air conditioner body 1. However, even in this connected state, the user can still remove the air outlet grille 2 from the air conditioner body 1 without the aid of tools.

[0095] Therefore, the locking member 3 is in a locked state, which restricts the movement of the air outlet grille 2 from the first end 21 to the second end 22, and locks the connection between the air outlet grille 2 and the air conditioner body 1. When the locking member 3 is in the locked state, the air outlet grille 2 cannot move from the first end 21 to the second end 22, so the air outlet grille 2 cannot be removed from the air conditioner body 1 by hand.

[0096] In some embodiments of this utility model, such as Figure 2 , Figure 7 and Figure 8 As shown, the first end 21 is the upper end of the air outlet grille 2, and the second end 22 is the lower end of the air outlet grille 2. The first end 21 has an upwardly extending pin 25. The air conditioner body 1 includes a bottom-open socket 13, and the pin 25 is inserted into the socket 13 from bottom to top. Figure 2 , Figure 9 and Figure 10 As shown, the air outlet grille 2 is located at the front of the air conditioner body 1. The air conditioner body 1 has an elastic cantilever 14 with its lower end fixed and its upper end able to swing elastically in the front-back direction below the air outlet 11. The lower end of the air outlet grille 2 has a support portion 26, and the upper end of the elastic cantilever 14 has a support portion 141 supported at the bottom of the support portion 26.

[0097] The air vent grille 2 moves from bottom to top so that the upper pin 25 is inserted into the socket 13, so that the first end 21 is inserted into the air conditioner body 1. The lower end of the air vent grille 2 is supported by the elastic cantilever 14, so that the upper end of the air vent grille 2 remains in the state of being inserted into the air conditioner body 1.

[0098] The bottom of the support part 26 is supported by the elastic cantilever 14. The elastic cantilever 14 can swing in the front and back direction to avoid the installation and disassembly path of the air outlet grille 2. Compared with a fixed support, it is easier for the user to disassemble and assemble the air outlet grille 2 and the air conditioner body 1 by hand.

[0099] For example, the process of installing the air vent grille 2 into the air conditioner body 1 is as follows: Figure 11As shown, the air vent grille 2 is tilted at a certain angle relative to the air conditioner body 1. The upper end of the air vent grille 2 is inserted into the socket 13 of the air conditioner body 1 from bottom to top. Then, the elastic cantilever 14 can swing forward to avoid the lower end of the air vent grille 2 moving backward. After the lower end of the air vent grille 2 moves into place, the elastic cantilever 14 is supported from below on the bottom of the support part 26, thereby limiting the position of the air vent grille 2. Next, the locking member 3 is inserted into the second end 22 and the air conditioner body 1 along the inside and outside direction of the air vent grille 2 to present a locked state, so as to restrict the movement of the air vent grille 2 along the direction from the first end 21 to the second end 22 so that the first end 21 is disengaged from the air conditioner body 1.

[0100] Similarly, the process of removing the air vent grille 2 from the air conditioner body 1 is as follows: First, use a tool to unlock the locking mechanism 3. Then, drive the bottom of the air vent grille 2 forward to break free from the limit of the elastic cantilever 14, and then detach the air vent grille 2 from the air conditioner body 1 from top to bottom.

[0101] In some embodiments of this utility model, such as Figure 8 As shown, the pin 25 has a limiting inclined surface 251, and the insertion hole 13 has a stop inclined surface 131 inside. The stop inclined surface 131 and the limiting inclined surface 251 cooperate to restrict the downward movement of the pin 25 and improve the insertion and engagement stability of the pin 25.

[0102] In some embodiments of this utility model, such as Figure 2 As shown, the width direction of the air outlet grille 2 is left-right. The width of the air outlet grille 2 in the left-right direction is greater than 1 / 2 of the overall width of the air conditioner 100 in the left-right direction. There are two elastic cantilever arms 14 arranged in the left-right direction. The two elastic cantilever arms 14 extend from bottom to top in a direction away from each other, so that the lower ends of the two elastic cantilever arms 14 are close to each other and the upper ends are far apart. Figure 9 As shown, the lower end of the air vent grille 2 has two support portions 26, which correspond to the upper ends of the two elastic cantilever arms 14 respectively, and the locking member 3 is located between the two support portions 26.

[0103] Two flexible cantilever arms 14 are provided, spaced apart in the left-right direction. Each of the two flexible cantilever arms 14 cooperates with a corresponding support part 26, which can improve the support stability of the air outlet grille 2. The locking member 3 is located between the two support parts 26, which can improve the connection stability of the air outlet grille 2.

[0104] The lower end of the elastic cantilever 14 is a fixed end, and the upper end of the elastic cantilever 14 is a free end. The two elastic cantilever arms 14 extend from bottom to top in a direction away from each other, so that the fixed ends of the two elastic cantilever arms 14 are close to each other, and the free ends of each elastic cantilever arm 14 are far apart. The structure of the elastic cantilever arm 14 allows the free end of the elastic cantilever arm 14 to swing elastically in the vertical direction. The upper end of the elastic cantilever arm 14 is supported on the bottom of the support part 26, which can improve the limiting effect on the air outlet grille 2 in the vertical direction.

[0105] In some embodiments of this utility model, the distance from the support part 141 to the end face where the insertion hole 13 is located in the vertical direction is less than the distance from the support part 26 to the first end 21. With this design, after the air outlet grille 2 is installed, it will press down on the elastic cantilever 14, and the elastic cantilever 14 will generate an upward elastic force, pushing the air outlet grille 2 upward, thereby limiting the air outlet grille 2 in the vertical direction, improving the assembly stability of the air outlet grille 2, and reducing the gap between the upper end of the air outlet grille 2 and the air conditioner after insertion, thus improving the overall integrity.

[0106] In some embodiments of this utility model, the interference fit between the air outlet grille 2 and the elastic arm is 3-6mm.

[0107] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the air conditioner body 1 includes a first mating part 12 located below the air outlet 11, and the air outlet grille 2 includes a second mating part 23 located in front of the first mating part 12. The locking member 3 passes through the second mating part 23 and the first mating part 12 from front to back. The lower part of the air outlet grille 2 is also provided with a limiting groove 27, which is set higher than the supporting part 26. The air conditioner body 1 also includes a protruding protrusion 15, and the limiting groove 27 is sleeved on the protrusion 15 to limit the relative movement of the air outlet grille 2 and the air conditioner body 1 in the vertical and horizontal directions.

[0108] The lower end of the air outlet grille 2 protrudes forward to form a limiting groove 27. During the installation of the air outlet grille 2 on the air conditioner body 1, the limiting groove 27 is sleeved on the protrusion 15. The protrusion 15 and the limiting groove 27 are engaged, thereby limiting the relative movement of the air outlet grille 2 relative to the air conditioner body 1 in the vertical and horizontal directions, which can improve the installation stability of the air outlet grille 2 relative to the air conditioner body 1.

[0109] In some embodiments of this utility model, such as Figure 9 and Figure 10 As shown, the upper end of the elastic cantilever 14 also has a stop portion 142 that stops in front of the support portion 26, and the lower end of the air outlet grille 2 is recessed to form the support portion 26.

[0110] The elastic cantilever 14 not only supports the bottom of the support part 26 from bottom to top, but also stops the support part 26 on the front side, which can limit the forward movement of the air outlet grille 2, reduce the possibility of the air outlet grille 2 tilting forward from top to bottom and detaching from the air conditioner body 1, and further restrict the air outlet grille 2 from detaching from the air conditioner body 1.

[0111] In some embodiments of this utility model, such as Figure 10 As shown, the front surface of the stop portion 142 is formed as a first guide slope 1421, which extends rearward from bottom to top to guide the support portion 26 over to the rear side of the upper end of the elastic cantilever 14. The rear surface of the stop portion 142 is formed as a second guide slope 1422, which extends forward from bottom to top to guide the support portion 26 over to the front side of the upper end of the elastic cantilever 14. The inclination angle of the first guide slope 1421 and / or the second guide slope 1422 relative to the vertical line is greater than 15°. The front surface of the support portion 26 is formed as a third guide slope, which inclines rearward from top to bottom. The inclination angle of the front surface of the support portion 26 relative to the vertical line is greater than 15°. The rear surface of the support portion 26 is formed as a fourth guide slope, which inclines forward from top to bottom. The inclination angle of the rear surface of the support portion 26 relative to the vertical line is greater than 15°.

[0112] The flexible cantilever 14 is also located in the front stop support 26. By forming guide slopes on the front and rear surfaces of the stop part 142 and the front and rear surfaces of the support 26, the air outlet grille 2 can be easily disassembled and assembled.

[0113] The front surface of the gear shift 142 is formed as a first guide slope 1421, and the rear surface of the support 26 is formed as a fourth guide slope. Both the first guide slope 1421 and the fourth guide slope extend forward from top to bottom. When the support 26 moves backward, the fourth guide slope contacts the first guide slope 1421, and the drive elastic cantilever 14 of the support 26 swings backward. The angle between the fourth guide slope and the first guide slope 1421 makes it easier for the support 26 to pass over the gear shift 142 and enter the rear side of the gear shift 142.

[0114] The rear surface of the gear position 142 is formed as a second guide slope 1422, and the front surface of the support portion 26 is formed as a third guide slope. The second guide slope 1422 and the third guide slope rib extend from top to bottom and rearward. When the support portion 26 moves forward, the third guide slope contacts the second guide slope 1422, and the drive elastic cantilever 14 of the support portion 26 swings forward. The angle between the third guide slope and the second guide slope 1422 makes it easier for the support portion 26 to pass over the gear position 142 and enter the front side of the gear position 142.

[0115] In some embodiments of this utility model, such as Figure 12 and Figure 13 As shown, the air outlet grille 2 has a rearward protruding third mating part 28 in the middle of its length direction, and the air outlet 11 has a crossbeam 16 extending along the width direction of the air outlet grille 2 and opposite to the third mating part 28. The crossbeam 16 has a fourth mating part 161. The third mating part 28 is engaged with the fourth mating part 161 by the movement of the air outlet grille 2 relative to the air conditioning body 1 from front to back.

[0116] The air vent grille 2 not only mates with the air conditioner body 1 at both ends along its length, but also mates with the air conditioner body 1 in the middle along its length. This improves the assembly stability of the air vent grille 2 and reduces the occurrence of the air vent grille 22 protruding in the middle, thereby reducing the gap between the air vent grille 2 and the air outlet 11 and improving the overall integrity.

[0117] When the air outlet grille 2 is installed on the air conditioner body 1, the air outlet grille 2 is tilted at a certain angle relative to the air conditioner body 1. The upper end of the air outlet grille 2 is inserted into the socket 13 of the air conditioner body 1 from bottom to top, and the lower part of the air outlet grille 2 moves backward relative to the air conditioner body 1. The third mating part 28 and the fourth mating part 161 are designed to be snapped together in the front and back direction, which can reduce the difficulty of operation.

[0118] In some other embodiments of this utility model, the third mating part 28 is engaged with the fourth mating part 161 by the upward movement of the air outlet grille 2 relative to the air conditioning body 1.

[0119] When the air outlet grille 2 is installed on the air conditioner body 1, its upper end is inserted into the socket 13 of the air conditioner body 1 from bottom to top. The third mating part 28 can be inserted and mated with the fourth mating part 161 as the air outlet grille 2 moves upward, which can reduce the difficulty of operation.

[0120] In some embodiments of this utility model, such as Figure 12 and Figure 13 As shown, the fourth mating part 161 is constructed as a column extending in the vertical direction, and the third mating part 28 is constructed as a fastener with an open rear side. The air outlet grille 2 moves relative to the air conditioning body 1 from front to back, and the fastener engages with the column rearward. Figure 2 and Figure 11 As shown, a decorative panel 17 is also provided on the outside of the crossbeam 16. The decorative panel 17 has a through hole 171, and the fastener can pass through the through hole 171 to fasten and engage with the column on the back side of the decorative panel 17.

[0121] In some embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 11As shown, the air conditioner 100 also includes a lower panel 4, which is mounted on the air conditioner body 1 and located below the air outlet 11. The lower panel 4 covers the elastic cantilever 14 and the locking member 3.

[0122] The bottom panel 4 can improve the overall integrity of the air conditioner 100, and can protect the rear elastic cantilever 14 and locking member 3, prevent accidental contact, and reduce contamination of the elastic cantilever 14 and locking member 3.

[0123] In some embodiments of this utility model, the air conditioner 100 further includes a locking mechanism, which has a locked state and an unlocked state. The locking mechanism can be switched between the locked state and the unlocked state by hand. In the locked state, the locking mechanism restricts the disassembly of the air outlet grille 2 relative to the air conditioner body 1.

[0124] The connection stability between the air outlet grille 2 and the air conditioner body 1 can be improved by setting a locking mechanism.

[0125] In some embodiments of this application, the air outlet grille 2 and the air conditioner body 1 can be disassembled and connected by hand. Users can assemble and connect the air outlet grille 2 and the air conditioner body 1 without the aid of tools. By setting a locking mechanism, after the air outlet grille 2 and the air conditioner body 1 are connected, the state of the locking mechanism is manually switched to the locked state, which provides a secondary guarantee for the installation of the air outlet grille 2. This improves the situation where the air outlet grille 2 accidentally falls off during the process of locking the connection between the locking member 3 and the air conditioner body 1, and can improve the stability of operation.

[0126] Furthermore, the locking mechanism can be switched manually, so even if the locking mechanism is in the locked state, the user can still switch the locking mechanism without tools and then remove the air vent grille 2 from the air conditioner body 1.

[0127] For example, the locking mechanism is constructed as a slider that slides on the air conditioner body 1. Manually driving the movement of the slider can drive the state switching of the locking mechanism. When the slider is in the locked state, at least a portion of the slider cooperates with the air outlet grille 2 to restrict the movement of the air outlet grille 2 in the vertical and horizontal directions, thereby restricting the disassembly of the air outlet grille relative to the air conditioner body 1.

[0128] In some embodiments of this utility model, the locking mechanism and the locking member 3 are independent of each other; and / or, during the connection process of the air outlet grille 2, the step of the locking mechanism switching from the unlocked state to the locked state is located before the step of the locking member 3 locking; during the disassembly overload of the air outlet grille 2, the step of the locking mechanism switching from the locked state to the unlocked state is located after the step of the locking member 3 unlocking.

[0129] The locking mechanism is only a safety device for the assembly connection of the air vent grille 2, and therefore does not interfere with the locking element 3, which is the main locking component. The state switching of the locking element 3 is the main factor in whether the air vent grille 2 can be removed.
