Detailed implementation manners

[0036] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0037] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments, and are not intended to limit the present invention.

[0039] Please refer to Figures 1 to 16 , an air conditioner chassis, including a main body 1, the main body 1 at least includes a main board 11 and an interchangeable part 12 which are detachably connected; a drainage channel 124 is arranged on the interchangeable part 12, and a drainage port 1241 is arranged through the bottom of the drainage channel 124; a drainage groove is arranged on the main board 11; and an anti-seepage component is further included, and this anti-seepage component is used to connect the drainage groove and the drainage channel 124. Specifically, as Figure 10 , Figure 11 , Figure 13 and Figure 14 shown, the main board 11 and the interchangeable part 12 here are detachably connected, so that the overall structure of the air conditioner chassis is modularly designed. Thus, during the production and processing process, when the model (length) of the air conditioner chassis changes, the air conditioner chassis does not need to be re-molded as a whole, but only needs to replace the interchangeable part 12 of different models (lengths), which can greatly save production costs. The air conditioner chassis here is applied to an indoor air conditioner. During the operation of the air conditioner, water droplets will condense on the air conditioner chassis. In this embodiment, the condensed water droplets gather in the drainage groove and flow to the drainage channel 124, and finally are discharged outside the air conditioner through the drainage port 1241. The main board 11 of the air conditioner chassis here is spliced by the main board 11 and the interchangeable part 12. Therefore, there will inevitably be a gap at the connection between the main board 11 and the interchangeable part 12, so that there is a risk of water seeping out through this gap during the process of water flowing from the drainage groove to the drainage channel 124. The anti-seepage component in this embodiment overlaps on this gap, one end of which is connected to the drainage groove and the other end is connected to the drainage channel 124, so that the water flow does not pass through the gap and realizes the flow from the drainage groove to the drainage channel 124, which is convenient for drainage and avoids the phenomenon of water seeping out through the gap, and has high safety.

[0040] Furthermore, as Figure 11 and Figure 13As shown, the drain trough includes an upper drain trough 111 and a lower drain trough 112. The upper drain trough 111 is distributed on the upper side of the lower drain trough 112, and both the upper drain trough 111 and the lower drain trough 112 are connected to the drain channel 124. The anti-seepage component includes a film sheet (not shown in the figure) and a water receiving tray 114, where: the film sheet is laid on the bottom of the upper drain trough 111 and extends into the drain channel 124; the water receiving tray 114 at least includes a water guiding part 1141 and a water collecting trough 1142 formed integrally. A water guiding groove 11411 communicating with the water collecting trough 1142 is provided on the water guiding part 1141. The water guiding part 1141 is snap-fitted to the lower drain trough 112, and the water collecting trough 1142 is snap-fitted to the drain channel 124 and communicates with the drain port 1241. The simultaneous action of the upper drain trough 111 and the lower drain trough 112 here can improve the drainage efficiency of the air conditioner chassis. In other embodiments, the number of drain troughs can be set as required without specific limitation. In this embodiment, the gap between the upper drain trough 111 and the drain channel 124 is covered by the film sheet, so as to avoid water leakage from this gap. Specifically, in use, first, the main board 11 and the interchangeable part 12 are fixedly installed, and then a complete film sheet is used. One end of it is attached to the inner side surface of the upper drain trough 111, and the other end is attached to the inner side surface of the drain channel 124. In this embodiment, preferably, the film sheet is a PVC film.

[0041] For the gap between the lower drain trough 112 and the drain channel 124, it is closed by the provided water receiving tray 114. Specifically, as Figure 11 、 Figure 12 、 Figure 13 and Figure 14 shown, the water guiding part 1141 and the water collecting trough 1142 are integrally formed here, so that water in the water guiding groove 11411 will not leak during the process of flowing into the water collecting trough 1142. In this embodiment, fixing ribs 1121 are arranged in the lower drain trough 112, and a second fixing groove 11412 adapted to the fixing ribs 1121 is arranged on the back side of the water guiding part 1141; a first fixing groove 115 is arranged on the inner side surface of the main board 11, and a limiting block 1143 adapted to the first fixing groove 115 is arranged on the water guiding part 1141; a drain pipe 11421 is arranged through the bottom of the water collecting trough 1142.

[0042] When in use, when the water guiding part 1141 is clamped to the lower drain trough 112, the fixing protrusion is embedded in the second fixing groove 11412, and the limiting block 1143 is embedded in the first fixing groove 115. At the same time, the water collecting trough 1142 is clamped in the drainage channel 124, and the drain pipe 11421 is embedded in the drain port 1241. Here, the drain pipe 11421, the second fixing groove 11412 and the limiting block 1143 can respectively cooperate with the main board 11 to realize the fixed installation of the water receiving tray 114 on the main board 11. It should be noted that when the water guiding part 1141 is installed in the lower drain trough 112, the water guiding part 1141 is closely attached to the upper inner wall of the lower drain trough 112, and the upper inner wall of the lower drain trough 112 extends to the upper side of the water guiding groove 11411, which can prevent the water droplets on the inner wall of the main board 11 from seeping into the gap between the water guiding part 1141 and the lower drain trough 112, thus causing water to seep out from the gap between the lower drain trough 112 and the drainage channel 124. In this embodiment, the water droplets on the main board 11 under the upper drain trough 111 all gather in the water guiding groove 11411.

[0043] On the one hand, the water receiving tray 114 here can be used to cover the gap between the lower drain trough 112 and the drainage channel 124, that is, to achieve the purpose of guiding the water flow in the lower drain trough 112 into the drainage channel 124, thus avoiding the phenomenon of water seepage from the gap between the lower drain trough 112 and the drainage channel 124; on the other hand, the water receiving tray 114 is integrally formed by the water guiding part 1141 and the water collecting trough 1142, and its structural strength is high. During use, the water collecting trough 1142 is clamped in the drainage channel 124, that is, connected to the interchange part 12, while the water guiding part 1141 and the limiting block 1143 are both connected to the main board 11. Therefore, the water receiving tray 114 can realize the fixed connection of the interchange part 12 and the main board 11, increasing the structural stability after the assembly of the interchange part 12 and the main board 11.

[0044] It should be noted that in other embodiments, in order to prevent water flow from seeping into the gap between the lower drain trough 112 and the drainage channel 124 due to water seeping from the gap between the water guiding part 1141 and the lower drain trough 112, during use, a film sheet can be first attached in the lower drain trough 112. One end of the film sheet is attached to the lower drain trough 112, and the other end is attached into the drainage channel 124; finally, the water receiving tray 114 is installed. In this way, even if water seeps from the gap between the water guiding part 1141 and the lower drain trough 112, this part of the water flow can flow along the film sheet in the lower drain trough 112 to the drainage channel 124 and be discharged from the air conditioner through the gap between the outer wall of the drain pipe 11421 and the inner wall of the drain port 1241.

[0045] One end of the above-mentioned film sheet is attached to the main board 11 and the other end is attached to the interchange part 12, which can further improve the structural stability after the assembly of the main board 11 and the interchange part 12 on the basis of the water receiving tray 114.

[0046] It should be noted that in some embodiments, the anti-seepage component only includes a film sheet, which is laid at the bottom of the drainage groove and extends to the drain port 1241. Specifically, film sheets are attached to both the upper drainage groove 111 and the lower drainage groove 112, and the other ends of the film sheets extend into the drainage channel 124 until the drain port 1241, that is, the inner walls of the drainage channel 124, the upper drainage groove 111, and the lower drainage groove 112 are all attached with film sheets, and the film sheets can block and seal the gaps between the upper drainage groove 111 and the drainage channel 124 and between the lower drainage groove 112 and the drainage channel 124, effectively preventing water seepage. In other embodiments, the anti-seepage component only includes a water receiving tray 114, that is, during use, water receiving trays 114 are installed in the upper drainage groove 111 and the lower drainage groove 112 respectively. It should be emphasized that the shape of the water receiving tray 114 installed in the upper drainage groove 111 can be adaptively adjusted according to the shape of the upper drainage groove 111, and it is only necessary to ensure that the water receiving tray 114 is fixed to the upper drainage groove 111 and one end of the water receiving tray 114 extends into the drainage channel 124.

[0047] In this embodiment, as Figure 8 , Figure 10 , Figure 13 and Figure 15 shown, a first extension plate 1111 is arranged at the bottom of the upper drainage groove 111, and the first extension plate 1111 overlaps with the interchange part 12 and extends into the drainage channel 124. Further, a closing plate 1242 is arranged on the side wall of the drainage channel 124 to cooperate with the first extension plate 1111. During use, the first extension plate 1111 overlaps on the upper side of the closing plate 1242 and extends into the drainage channel 124. On the one hand, it can increase the connection area between the interchange part 12 and the main board 11 and improve the structural stability after the interchange part 12 and the main board 11 are installed; on the other hand, it can guide the water flow in the upper drainage groove 111 through the first extension plate 1111 so that it can better flow into the drainage channel 124. In other embodiments, a film sheet may not be provided in the upper drainage groove 111, but the first extension plate 1111 and the closing plate 1242 are used to prevent the water flow in the upper drainage groove 111 from seeping out through the gap between the upper drainage groove 111 and the drainage channel 124.

[0048] As Figure 10 and Figure 14 shown, a second extension plate 126 is arranged at the bottom of the drainage channel 124, and the second extension plate 126 is distributed near the drain port 1241; when the water collecting groove 1142 is clamped to the drainage channel 124, the second extension plate 126 is distributed on the upper side of the water collecting groove 1142, and the second extension plate 126 extends above the water collecting groove 1142. In this embodiment, the second extension plate 126 is arranged to incline downward, which can smoothly guide the water flow in the drainage channel 124 into the water collecting groove 1142.

[0049] In this embodiment, as Figure 9 , Figure 10 , Figure 15 and Figure 16 shown, the interchange part 12 includes a second seat body 122; a limiting groove 125 is arranged at the first end of the second seat body 122; a limiting rib 116 adapted to the limiting groove 125 is arranged at the first end of the main board 11, and the limiting rib 116 is snapped into the limiting groove 125. Further, a plurality of convex strips 3 are arranged on the outer side surface of the limiting groove 125 and the outer side surface of the limiting rib 116. In this embodiment, the limiting rib 116 is integrally formed with the main board 11 and is a flanging 221 at the end of the main board 11, and the limiting rib 116 extends along the direction away from the back side of the main board 11. The plurality of convex strips 3 are evenly distributed at intervals, which can effectively improve the structural strength of the limiting rib 116 and the limiting groove 125, so that the interchange part 12 and the main board 11 can be disassembled and assembled multiple times without being damaged, which is beneficial to the maintenance and repair of the equipment.

[0050] As Figure 11 shown, a first fixing screw hole 123 is arranged on the second seat body 122, and a second fixing screw hole 113 corresponding to the first fixing screw hole 123 one by one is arranged on the main board 11. When in use, after the main board 11 and the interchange part 12 are assembled, the first fixing screw hole 123 and the corresponding second fixing screw hole 113 are coaxial, and the interchange part 12 and the main board 11 are fixedly connected by screws or bolts, which is convenient for the disassembly and assembly of the main board 11 and the interchange part 12.

[0051] This embodiment also provides an air conditioner, which includes a fresh air base 2 and the above-mentioned air conditioner chassis; the fresh air base 2 is detachably connected to the interchange part 12. The air conditioner here has strong airtightness, and the phenomenon of water seepage in the air conditioner chassis can be avoided during use. At the same time, a fresh air device can be installed through the fresh air base 2, which helps to improve the air quality of the indoor space.

[0052] Specifically, as Figures 1 to 9 shown, the fresh air base 2 at least includes a first seat body 21, a first connecting plate 23 is arranged at one end of the first seat body 21, a first clamping convex 231 is arranged on the outer side surface of the first connecting plate 23, and the first clamping convex 231 is arranged in a ring along the outer edge of the first connecting plate 23; it also includes a plurality of first rib plates 232, and the plurality of first rib plates 232 are arranged on the outer side surface of the first connecting plate 23 and are distributed in the area defined by the first clamping convex 231. As Figure 1As shown, the first card projection 231 here is arranged in a closed shape around the first connecting plate 23. On the one hand, it can act on the first connecting plate 23 to increase the structural strength of the first connecting plate 23; on the other hand, it extends in a direction away from the outer side surface of the first connecting plate 23 to form a convex structure. This convex structure facilitates the assembly of the fresh air base 2 and the interchangeable part 12, and is convenient for installation and disassembly. In addition, several first rib plates on the first connecting plate 23 cooperate with the first card projection 231 to further improve the structural strength of the first connecting plate 23, which can effectively improve the service life of the fresh air base 2. Further, in this embodiment, several first rib plates are evenly spaced. The evenly spaced several first rib plates make the structural strength of each area on the first connecting plate 23 tend to be the same, and the structural stability is good. Preferably, the end of the first rib plate 232 abuts against the inner side surface of the first card projection 231. The first rib plate and the first card projection 231 are integrally formed. The first rib plate extends to the first card projection 231 to form a support for it, so that the structural strength of the first card projection 231 is strengthened, which can ensure the stability of the fresh air base 2 after installing the fresh air equipment and the safety of the assembly of the fresh air base 2 and the interchangeable part 12; at the same time, the first card projection 231 with improved structural strength can ensure that the fresh air base 2 is not easily damaged structurally after being disassembled and assembled with the interchangeable part 12 for multiple times, which is convenient for the maintenance of the fresh air equipment and the interchangeable use of the fresh air base 2, and has strong practicability.

[0053] Further, as Figure 1 and Figure 2 shown, the other end of the first base body 21 is provided with a shaping plate 22. The area composed of the shaping plate 22, the first base body 21 and the first connecting plate 23 is an installation cavity. In this embodiment, the fresh air equipment is installed in the installation cavity. The first base body 21, the first connecting plate 23 and the shaping plate 22 here all provide support for the fresh air equipment and fix it in the installation cavity, which can improve the stability of the installation of the fresh air equipment; at the same time, the installation cavity here is convenient for the quick positioning and assembly of the fresh air equipment. As Figure 2 shown, in this embodiment, the outer edge of the shaping plate 22 is provided with a flanging 221, and several third rib plates 222 are arranged on the outer side surface of the shaping plate 22. The several third rib plates 222 here are evenly spaced. The flanging 221 and the third rib plates 222 in this embodiment are both beneficial to improving the structural strength of the shaping plate 22.

[0054] In this embodiment, the inner side surface of the first base body 21 is the inner side surface of the bottom of the installation cavity. As Figure 1As shown in the figure, a longitudinal reinforcing plate 212 and a transverse reinforcing plate 213 are respectively arranged on the inner side surface of the first base body 21. The longitudinal reinforcing plate 212 and the transverse reinforcing plate 213 are vertically and cross - distributed, so that the structural strength of part or all of the inner side surface area of the first base body 21 is enhanced, which is beneficial to improving the safety after the fresh - air base 2 is assembled with the fresh - air equipment, and enhancing the structural strength of the fresh - air base 2, thereby helping to extend the service life of the fresh - air base 2. In this embodiment, the longitudinal reinforcing plate 212, the transverse reinforcing plate 213 and the first base body 21 are integrally formed.

[0055] Furthermore, mounting screw holes 24 are arranged on the shaping plate 22 and / or the first base body 21 and / or the first connecting plate 23. The mounting screw holes 24 are used to fixedly install the fresh - air equipment in the installation cavity through screws or bolts. In this embodiment, specifically, as Figure 1 shown, in order to facilitate the fixation of the fresh - air equipment, mounting screw holes 24 are arranged on the shaping plate 22, the first base body 21 and the first connecting plate 23. In this embodiment, a anti - misalignment notch 25 is arranged on the first base body 21. The anti - misalignment notch 25 facilitates the quick and correct installation of the fresh - air equipment. In this embodiment, the mounting screw holes 24 on the first base body 21 are arranged at the bottom of the anti - misalignment notch 25. The structure is simple and convenient for processing.

[0056] Furthermore, in order to stably install the fresh - air equipment, a positioning plane 241 is arranged at the open end of the mounting screw hole 24. The positioning plane 241 can effectively increase the fixed - connection area between the fresh - air equipment and the fresh - air base 2, and can effectively improve the installation stability of the fresh - air equipment.

[0057] In this embodiment, preferably, the shaping plate 22, the first base body 21 and the first connecting plate 23 are integrally formed. The fresh - air base 2 is formed by die pressing, with high processing efficiency and high structural strength.

[0058] As Figure 1 shown, a notch 211 is penetrated and arranged on the first base body 21. The notch 211 facilitates the routing of the fresh - air duct.

[0059] As Figure 2 shown, in order to facilitate the fixed connection between the fresh - air base 2 and the interchangeable part 12, a fifth fixing screw hole 233 is penetrated and arranged on the first connecting plate 23; a sixth fixing screw hole (not shown in the figure) is arranged on the first convex 231. During use, when the first convex 231 is assembled with the interchangeable part 12, the fresh - air base 2 and the interchangeable part 12 are fixedly connected by setting screws or bolts in the fifth fixing screw hole 233 and the sixth fixing screw hole, which is convenient for the disassembly and assembly of the fresh - air base 2.

[0060] In this embodiment, as Figure 4 、 Figure 5 、 Figure 7 and Figure 9As shown, a second connecting plate 121 is disposed at the first end of the second body 122, and a second engaging convex 1211 adapted to the first engaging convex 231 is disposed on the outer side surface of the second connecting plate 121; the second engaging convex 1211 is arranged in a ring along the outer edge of the second connecting plate 121; a plurality of second rib plates 1212 are disposed on the outer side surface of the second connecting plate 121, and the plurality of second rib plates 1212 are distributed in the area defined by the second engaging convex 1211; the first engaging convex 231 is sleeved outside the second engaging convex 1211, or the second engaging convex 1211 is sleeved outside the first engaging convex 231; the first rib plate 232 and the second rib plate 1212 are staggered. In this embodiment, the first engaging convex 231 cooperates with the second engaging convex 1211. Preferably, the second engaging convex 1211 is disposed on the second connecting plate 121 in a closed shape, and the outer shape of the second engaging convex 1211 is adapted to the outer shape of the first engaging convex 231.

[0061] In this embodiment, taking the example that the second engaging convex 1211 is sleeved outside the first engaging convex 231 for illustration.

The area enclosed by the closed shape of the second engaging convex 1211 here is larger than the area enclosed by the closed shape of the first engaging convex 231, and after the first connecting plate 23 and the second connecting plate 121 are assembled, the outer side surface of the first engaging convex 231 is attached to the inner side surface of the second engaging convex 1211, making the structure more firm after the first engaging convex 231 and the second engaging convex 1211 are assembled. For the convenience of assembling the first engaging convex 231 and the second engaging convex 1211, there is an assembly gap between the second rib plate 1212 and the inner side surface of the second engaging convex 1211, and the width of the assembly gap is larger than the thickness of the first engaging convex 231.

[0063] As Figure 5 shown, the first rib plate 232 and the second rib plate 1212 are staggered, so that the first rib plate 232 and the second rib plate 1212 form a grid-like structure in the cavity defined by the first connecting plate 23, the first engaging convex 231, the second connecting plate 121 and the second engaging convex 1211, with high strength.

[0064] In this embodiment, a third fixing screw hole 12111 corresponding to the sixth fixing screw hole is arranged on the second clamping projection 1211. During use, after the first clamping projection 231 and the second clamping projection 1211 are assembled, the sixth fixing screw hole and the corresponding third fixing screw hole 12111 are coaxial. Further, a fourth fixing screw hole (not shown in the figure) corresponding to the fifth fixing screw hole 233 is penetratingly arranged on the second connecting plate 121. During use, after the first clamping projection 231 and the second clamping projection 1211 are assembled, the fifth fixing screw hole 233 and the corresponding fourth fixing screw hole are coaxial. This facilitates the use of screws or bolts to fixedly connect the fresh air base 2 and the interchangeable part 12, making it convenient for disassembly and assembly.
