[0040] In most single-flow floor-standing air conditioners on the market, the air outlet components are all fixedly assembled, making it inconvenient to disassemble them. The air outlet grille, in particular, easily accumulates dust, requiring regular removal and cleaning. This inconvenience causes significant problems for users.

[0041] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown in the figure, an air conditioner 100 provided in one embodiment of this application includes an air outlet grille 10 and an air outlet frame 20. The air outlet frame 20 has an air outlet, and the air outlet grille 10 is installed at the air outlet position to allow air to be discharged from the air conditioner 100. The air outlet grille 10 includes a grille body 11, a retaining plate 12, and a locking assembly 13. The retaining plate 12 is disposed at either the upper or lower end of the grille body 11. The locking assembly 13 is slidably disposed on the retaining plate 12. The air outlet frame 20 has a spring buckle 21, which is disposed at the position corresponding to the retaining plate 12, and the retaining plate 12 is mounted on the spring buckle 21. The air outlet frame 20 is provided with a locking groove 22 at the position corresponding to the locking assembly 13, and the locking assembly 13 is inserted into the locking groove 22 to lock the air outlet grille 10. In this embodiment, the clip 12 at the upper or lower end of the grille body 11 is installed at the snap position of the air outlet frame 20 and locked by the locking assembly 11. This application first installs the end of the grille body 11 on the air outlet frame 20 and then locks it by the locking assembly 11 to facilitate the installation and removal of the air outlet grille 11.

[0042] One end of the upper or lower part of the grille body 11 is inserted into the corresponding position of the air outlet frame 20. The air conditioner 100 of this application can be a single cross-flow floor-standing air conditioner 100. The air conditioner 100 includes an air outlet grille 10 and an air outlet frame 20 assembled together. Both the air outlet grille 10 and the air outlet frame 20 are vertically installed. The air outlet frame 20 has an air outlet, and the air outlet grille 10 is installed at the position of the air outlet. The air outlet grille 10 includes a grille body 11, a retaining plate 12, and a locking assembly 13. Either the upper or lower part of the grille body 11 is inserted into the corresponding position of the upper or lower part of the air outlet frame 20. For example, the upper part of the grille body 11 is inserted into the upper part of the air outlet frame 20, or the lower part of the grille body 11 is inserted into the lower part of the air outlet frame 20. The retaining plate 12 is provided at the other end of the upper or lower part of the grille body 11. The upper end of the grille body 11 is inserted into the upper end of the air outlet frame 20, and the retaining plate 12 is set at the lower end of the grille body 11. The air outlet frame 20 has a spring buckle 21 at the position corresponding to the retaining plate 12, and the retaining plate 12 is engaged with the spring buckle 21. The locking component 13 is slidably disposed on the retaining plate 12, and the air outlet frame 20 is provided with a locking groove 22, which is disposed at the position corresponding to the locking component 13, and the locking component 13 is inserted into the locking groove 22.

[0043] When assembling the air outlet grille 10 of the air conditioner 100 of this application, one end of the upper or lower end of the grille body 11 is first inserted into the corresponding end of the air outlet frame 20 to pre-position the air outlet grille 10 at this end. Then, the retaining plate 12 at the other end is pressed against the spring clip 21 of the air outlet frame 20 to engage the retaining plate 12 at the position of the spring clip 21, thereby initially fixing both the upper and lower ends of the grille body 11. The engagement between the spring clip 21 and the retaining plate 12 is a detachable structure. Finally, the locking assembly 13 is slid to insert the locking assembly 13 into the locking groove 22, thereby locking the air outlet grille 10.

[0044] Understandably, one end of the grille body 11, either the upper or lower end, is inserted into the corresponding position of the air outlet frame 20. Specifically, this can be achieved through a pin and a socket connection. For example, a pin portion 14 can be provided at the upper end of the grille body 11 (see...). Figure 10 An insertion hole is provided at the position corresponding to the pin part 14 on the air outlet frame 20 to realize the insertion connection between the air outlet frame 20 and the grille body 11. Alternatively, the pin part 14 can be provided on the air outlet frame 20, and the insertion hole can be provided at the upper end of the grille body 11. During assembly, the insertion hole on the grille body 11 is simply fitted onto the pin part 14 on the air outlet frame 20.

[0045] like Figure 2 As shown, in an optional embodiment, the retaining plate 12 is disposed at the lower end of the grille body 11, and the upper end of the grille body 11 is inserted into the upper end of the air outlet frame 20 via the pin portion 14. In this embodiment, the grille body 11, the pin portion 14, and the retaining plate 12 can be integrally formed, for example, the grille body 11, the pin portion 14, and the retaining plate 12 can be integrally injection molded plastic parts. Assembling the grille body 11, the pin portion 14, and the retaining plate 12 as an integrally formed component can reduce the number of parts and the assembly process.

[0046] Please refer to Figure 4 , Figure 10 , Figure 11 and Figure 12 As shown, in an optional embodiment, the air conditioner 100 further includes a pressure plate 30, which is fixedly mounted on the air outlet frame 20. At least one elastic buckle 15 is provided at the center of the grille body 11. The pressure plate 30 has a snap-fit ​​post 31 adapted to the elastic buckle 15.

[0047] Specifically, the air conditioner 100 also includes a pressure plate 30 fixedly installed on the air outlet frame 20, and the pressure plate 30 has a snap-fit ​​post 31. At least one elastic buckle 15 is provided on the grille body 11, located near the middle of the grille body 11, facing the pressure plate 30, and used to snap the snap-fit ​​post 31. Since the air outlet grille 10 is relatively long, fixing only the upper and lower ends of the air outlet grille 10 does not provide high stability. Therefore, an additional positioning point is added near the middle of the air outlet grille 10. In this embodiment, the air outlet grille 10 is positioned at three locations: the upper end, the lower end, and the middle, allowing the air outlet grille 10 to be stably fixed to the air outlet frame 20. The pressure plate 30 can be fixed to the air outlet frame 20 using screws. A cover plate is also provided on the pressure plate 30. Since the pressure plate 30 is fixed with screws, the user can directly see the screws on the pressure plate 30 through the air outlet grille 10; therefore, a cover plate is provided to cover the pressure plate 30. In some embodiments, the pressure plate 30 can be integrally formed with the air outlet frame 20.

[0048] Please refer to Figure 11 and Figure 12 As shown, the elastic buckle 15 includes an elastic wall 151 and two fixed walls 152, with the elastic wall 151 positioned between the two fixed walls 152. One end of the elastic wall 151 is connected to one fixed wall 152, and the other end is connected to the other fixed wall 152. The elastic wall 151 forms an elastic fastening groove 153 with an arc-shaped cross-section, and the outer diameter of the locking post 31 is adapted to the diameter of the arc-shaped elastic fastening groove 153. The arc-shaped elastic wall 151 has an inlet 154 through which the locking post 31 enters the elastic fastening groove 153. When the locking post 31 is engaged, the inlet 154 deforms to allow the locking post 31 to enter. After the locking post 31 has entered, the inlet 154 returns to its initial state, thus securing the locking post 31 within the elastic fastening groove 153.

[0049] During assembly, align the snap-fit ​​post 31 on the pressure plate 30 with the inlet 154 of the elastic fastening groove 153, and then press the corresponding position of the air outlet grille 10 to fasten the snap-fit ​​post 31 into the elastic fastening groove 153. In this embodiment, the elastic buckle 15 and the air outlet grille 10 are integrally injection molded. Two fixed walls 152 are respectively connected to the inward-facing side of the air outlet grille 10. A connecting wall 155 is also provided on the elastic wall 151, with one end of the connecting wall 155 connected to the inward-facing side of the air outlet grille 10 and the other end connected to the elastic wall 151.

[0050] Please refer to Figure 6 and Figure 13As shown, in an optional embodiment, the snap-on 21 on the air outlet frame 20 has a free end 211 and a fixed end 212 connected together. The fixed end 212 is fixedly connected to the air outlet frame 20, and the free end 211 is elastically engaged with the latch plate 12.

[0051] Specifically, the spring clip 21 has a free end 211 and a fixed end 212. The fixed end 212 is connected to the lower end of the air outlet frame 20, and the free end 211 is located on the side of the fixed end 212 closer to the retaining plate 12. The spring clip 21 is inclined to provide sufficient elasticity for elastic deformation. When installing the air outlet grille 10, the retaining plate 12 will compress and deform the free end 211 of the spring clip 21, causing it to deform towards the fixed end 212. After the retaining plate 12 is installed in place, the free end 211 returns to its initial state. In some embodiments, the lower end of the air outlet grille 10 and the spring clip 21 are interference-fitted in the vertical direction. The interference amount is designed according to the size and weight of the unit. The interference amount ranges from 3mm to 6mm. At this time, after the free end 211 of the spring clip 21 is engaged with the retaining plate 12, the free end 211 cannot return to its initial state. The spring clip 21 is in a slightly deformed state, providing a certain elastic force to the retaining plate 12.

[0052] Please refer to Figure 7 As shown, in an optional embodiment, the latch 12 includes a first guide ramp 121 and a second guide ramp 122 disposed opposite to each other. The free end 211 of the snap 21 has a fourth guide ramp for guiding the second guide ramp 122 and a third guide ramp 213 for guiding the first guide ramp 121.

[0053] Specifically, the first guide slope 121 is used in conjunction with the third guide slope 213, and the second guide slope 122 is used in conjunction with the fourth guide slope 214. During assembly, the first guide slope 121 of the locking plate 12 first abuts against the third guide slope 213 of the spring clip 21. Then, the user presses the locking plate 12 so that the first guide slope 121 of the locking plate 12 slides along the third guide slope 213 until it slides into place. When removing the air outlet grille 10, first slide the locking assembly 13 out of the locking groove 22 to unlock the air outlet grille 10. Then, pull the lower end of the air outlet grille 10 outward. During the process of pulling out the lower end of the air outlet grille 10, the second guide slope 122 of the locking plate 12 abuts against the fourth guide slope 214 of the spring clip 21. Then, the second guide slope 122 of the locking plate 12 slides out along the fourth guide slope 214 until the locking plate 12 is completely slid out. Then, the user can pull out the upper end of the air outlet grille 10. This application provides a first guide slope 121 and a third guide slope 213 to facilitate the locking plate 12 to engage with the spring clip 21; and a second guide slope 122 and a fourth guide slope 214 to facilitate the separation of the locking plate 12 from the spring clip 21, thereby enabling convenient disassembly and assembly of the air outlet grille 10 and facilitating the user's disassembly and assembly of the air outlet grille 10 in the future.

[0054] Please refer to Figure 5 , Figure 8 and Figure 9 As shown, in an optional embodiment, the locking assembly 13 includes a limiting pin 131 and a toggle button 132 connected to each other. The locking plate 12 has a sliding groove 123, and the toggle button 132 is slidably disposed in the sliding groove 123. The sliding direction of the toggle button 132 is up and down. The limiting pin 131 is inserted into the locking groove 22 to lock the lower end of the air outlet grille 10.

[0055] Specifically, the slide groove 123 penetrates the retaining plate 12, its length is longer than the toggle button 132, and its width is adapted to the width of the toggle button 132, so that the toggle button 132 can slide up and down in the slide groove 123. The toggle button 132 is exposed to the outside for the user to operate from the outside. The connection between the toggle button 132 and the limiting pin 131 can be a snap-fit ​​connection. When assembling the locking assembly 13, the toggle button 132 is inserted into the slide groove 123; the limiting pin 131 is placed inside the retaining plate 12 and aligned with the toggle button 132; then the toggle button 132 is snapped onto the limiting pin 131, so that the locking assembly is installed in the slide groove 123, and the locking assembly 13 can slide in the slide groove 123. When the user locks the device, the toggle button 132 can be moved up and down from the outside. This movement causes the limit pin 131 to slide up and down, inserting or removing it from the locking groove 22, thereby locking and releasing the lower end of the air vent grille 10. It should be noted that a slide rail can also be provided on the limit pin 131, and a sliding groove adapted to this slide rail can be provided on the locking plate 12. The two slide rails make the entire locking assembly slide more smoothly.

[0056] Please refer to this again. Figure 8 As shown, in this embodiment, the outer surface of the toggle button 132 has multiple protrusions 1321. When the user toggles the toggle button 132, their hand presses against it, and the friction between the hand and the outer surface of the toggle button 132 causes it to slide. The protrusions 1321 on the outer surface of the toggle button 132 increase the friction between the hand and the toggle button 132, facilitating the user's movement of the toggle button 132. Understandably, other structures that increase friction, such as a frosted surface, can also be provided on the outer surface of the toggle button 132. It should be noted that protrusions can also be provided on the outer surface of the toggle button 132, protruding outwards to facilitate direct toggle by hand. The specific structure can be designed according to actual needs and is not limited here.

[0057] Please refer to Figure 5 , Figure 6 and Figure 13As shown, in an optional embodiment, the air outlet frame 20 includes a frame 23, a mounting plate 24, and an inner plate 25. Both the mounting plate 24 and the inner plate 25 are fixedly mounted on the lower end of the frame 23. A spring clip 21 is disposed on the mounting plate 24, and a locking groove 22 is disposed on the inner plate 25. In this embodiment, the air outlet frame 20 is an assembled structure, composed of the frame 23, the mounting plate 24, and the inner plate 25. The mounting plate 24 is fixed to the lower end of the frame 23 by screws, so that the spring clip 21 on the mounting plate 24 corresponds to the position of the locking plate 12, thereby engaging the locking plate 12 with the spring clip 21. The inner plate 25 can be fixed to the mounting plate 24 or the frame 23 by screws, and the locking groove 22 on the inner plate 25 corresponds to the position of the locking assembly 13, so that the locking assembly 13 can slide into and out of the locking groove 22. In an optional embodiment, the locking groove 22 and the inner plate 25 are integrally injection molded. Mounting plate 24 and spring clip 21 are integrally injection molded. Mounting plate 24 has a recessed cavity 241, and spring clip 21 is disposed in the recessed cavity 241. Mounting plate also has a handle indicator 242, which is located below locking groove 22 and is used to indicate to the user that this is the disassembly position.

[0058] Please refer to Figure 2 and Figure 3 As shown, the air conditioner 100 also includes a lower panel 40 and a housing 50. The air outlet frame 20 is disposed inside the housing 50, and the lower panel 40 is detachably mounted on the housing 50, and the lower panel 40 blocks the lower end of the air outlet frame 20.

[0059] Specifically, the housing 50 is rectangular in shape and includes a rear box 51, a panel 52, a top cover 53, and a chassis 54. The rear box 51, panel 52, top cover 53, and chassis 54 are assembled together to form a box structure with internal accommodating space. The air outlet frame 20 is disposed inside the housing 50, and the lower panel 40 is mounted on the panel 52 of the housing 50. The lower panel 40 is positioned directly opposite the lower end of the air outlet grille 10 to block the lower end of the air outlet grille 10. The lower panel 40 and the panel 52 are connected by a snap-fit ​​mechanism to achieve a detachable connection between the two. When removing the air outlet grille 10, the user needs to first remove the lower panel 40, then slide the locking assembly 13 out of the locking groove 22, then pull the clip 12 out of the spring clip 21, and finally completely remove the air outlet frame 20.
