[0002] In order to collect and discharge the condensed water generated during heat exchange in the indoor unit outdoors, a water receiving tray is generally provided in the indoor unit.

[0003] However, the inventor found that when the indoor unit is in the cooling mode, the temperature of the water collected in the water receiving tray is relatively low. After the external air enters the space between the water receiving plate and the volute tongue, it is easy to cause condensed water to form on the outer side of the water receiving tray. Since it is on the outer side of the bottom wall of the water receiving tray. The condensed water formed on the bottom wall will fall on the volute tongue, and thus will flow out of the indoor unit from the joint gaps of the components, affecting normal use.

[0068] Embodiment

[0069] The inventor found that when the indoor unit is refrigerating, the temperature of the water received in the water receiving tray is relatively low. After the external air enters the space between the water receiving plate and the volute tongue part, it is easy to cause condensed water to form on the outer side of the water receiving tray. Since it will be on the outer side of the bottom wall of the water receiving tray. The condensed water formed on the bottom wall will fall on the volute tongue part, and thus will flow out of the indoor unit from the joint gap of the components, affecting normal use.

[0070] To solve the above problems, please refer to Figure 1 , this embodiment provides an air conditioner, which includes an indoor unit 100 and an outdoor unit. Generally, the indoor unit 100 and the outdoor unit are connected through a heat exchange pipeline to realize the adjustment of the indoor environment.

[0071] Please refer to Figure 1 and Figure 2 , in this embodiment, the indoor unit 100 includes a base 110, a water receiving tray part 130, a volute tongue part 150, a middle frame 170, a guide vane mounting bracket 190, a heat exchanger 231, and a sealing cotton 233. The heat exchanger 231 is installed on the base 110, and the water receiving tray part 130 is also installed on the base 110 and is located at the bottom of the heat exchanger 231 to receive the condensed water of the heat exchanger 231. The volute tongue part 150 is arranged on the base 110. The middle frame 170 is provided with an air outlet 171. One end of the guide vane mounting bracket 190 abuts against the end of the volute tongue part 150, and the other end abuts against the upper end of the middle frame 170 where the air outlet 171 is located. The sealing cotton 233 is arranged between the guide vane mounting bracket 190 and the water receiving tray part 130 for sealing.

[0072] In this embodiment, the guide vane mounting bracket 190 is provided and abuts against the volute tongue part 150, so that the guide vane mounting bracket 190 can extend the volute tongue part 150 to increase the air outlet 171 and the manufacture of the base 110. And a sealing cotton 233 is arranged between the guide vane mounting bracket 190 and the water receiving tray part 130, so as to realize the sealing between the two by the abutting extrusion between the guide vane mounting bracket 190 and the outer wall of the water receiving tray part 130, so that external air will not enter, thus improving the problem of condensed water forming on the outer side of the water receiving tray.

[0073] It should be noted that the air deflector mounting bracket 190 can be understood as an extension of the volute tongue portion 150, and it extends to the air outlet 171 through the splicing of the air deflector mounting bracket 190, which can reduce the mold and the design difficulty of the grinding mold. Secondly, the base 110, the volute tongue portion 150, and the water receiving tray portion 130 can be integrally formed or separately processed and then assembled together.

[0074] In this embodiment, the base 110 and the water receiving plate portion are integrally formed, and the volute tongue portion 150 is installed on the water receiving tray portion 130 through a snap connection structure.

[0075] In this embodiment, the sealing cotton 233 is a sponge, which has good elasticity and a weak texture, and can achieve good sealing after being extruded. And the sponge can also absorb water. In the case of a small amount of condensation, the condensation can be absorbed by the sponge, thus avoiding flowing out of the indoor unit 100.

[0076] In this embodiment, the indoor unit 100 further includes a lower air duct housing portion and a wind blade. The lower air duct housing portion is integrally formed with the base 110 or assembled to the base 110, so as to form a volute with the volute tongue portion 150. The wind blade is rotatably installed in the volute, and an air duct is formed between the lower air duct housing portion and the volute tongue portion 150. The air duct is communicated with the air outlet 171.

[0077] Please refer to Figures 2 to 5 , in this embodiment, a rib 191 along the length direction of the air deflector mounting bracket 190 is provided on one side of the air deflector mounting bracket 190 close to the water receiving tray portion 130. The rib 191 can make the sealing cotton 233 abut against the outer wall of the water receiving tray portion 130.

[0078] In this embodiment, by providing the rib 191 on one side of the air deflector mounting bracket 190 close to the water receiving tray portion 130, the rib 191 is used to extrude the sealing cotton 233, so that the sealing between the water receiving tray portion 130 and the air deflector mounting bracket 190 is tighter.

[0079] In this embodiment, the water receiving tray portion 130 includes a first side plate and a second side plate arranged oppositely and a bottom plate connected between the first side plate and the second side plate. The first side plate extends obliquely towards the direction of the middle frame 170, and the second side plate is arranged obliquely. In this way, the condensed water on the heat exchanger 231 can fall on the first side plate and be guided to the bottom plate through the first side plate. Generally, drainage holes are provided on the bottom plate, and the water flowing to the bottom plate can flow to the outside through the drainage holes and the drainage pipeline.

[0080] In this embodiment, the rib 191 is provided at a position corresponding to the front end of the bottom wall of the air deflector mounting bracket 190 and the water receiving tray portion 130.

[0081] Since the water receiving tray part 130 is connected to a drain pipe for draining water outdoors, generally only the bottom of the water receiving tray part 130 will have condensation over a large area, and generally condensation will form on the outer side of the bottom wall of the water receiving tray part 130. In this embodiment, the convex rib 191 is arranged at a position corresponding to the front end of the bottom wall of the water receiving tray part 130 on the air guide plate mounting bracket 190, so that the sealing cotton 233 abuts against the front end of the bottom surface of the water receiving tray part 130, thereby avoiding the formation of condensation on the outer side of the bottom wall of the water receiving tray part 130, and sealing can be achieved with a small amount of sealing cotton 233.

[0082] Please refer to Figures 2 to 5 , in this embodiment, the convex rib 191 includes a first convex rib 193 and a second convex rib 195 that are arranged at intervals in the width direction of the air guide plate mounting bracket 190. A plurality of connecting ribs 197 are arranged at intervals in the length direction of the air guide plate mounting bracket 190 between the first convex rib 193 and the second convex rib 195. One ends of the plurality of connecting ribs 197 are all connected to the first convex rib 193, and the other ends are connected to the second convex rib 195.

[0083] In this embodiment, the convex rib 191 is set as two sealing ribs arranged in a complicated way, so that double-layer sealing can be realized, and the sealing cotton 233 corresponding to the interval can be made to protrude inward, so that the sealing effect is better and it is convenient for installation.

[0084] In some embodiments of the present application, the sealing cotton 233 includes a first sealing cotton and a second sealing cotton. The first sealing cotton is arranged on the outer side of the water receiving tray part, and the second sealing cotton is arranged on the inner side of the air guide plate mounting bracket. This can solve the problem of condensation on the outer side of the water receiving tray part and the inner side of the air guide plate mounting bracket while solving the sealing problem. After assembly, the first sealing cotton and the second sealing cotton abut against each other to solve the sealing problem.

[0085] Please refer to Figures 4 to 7 , in this embodiment, a first connecting part 199 is arranged on one side in the width direction of the air guide plate mounting bracket 190, and a second connecting part 201 is arranged on the other side. The water receiving tray part 130 is provided with a third connecting part 131 corresponding to and connected to the first connecting part 199. The volute tongue part 150 is provided with a fourth connecting part 151 connected to the second connecting part 201. The first connecting part 199 is correspondingly connected to the third connecting part 131, and the second connecting part 201 is correspondingly connected to the fourth connecting part 151.

[0086] In this embodiment, the first connecting part 199 and the second connecting part 201 are arranged on the air guide plate mounting bracket 190, the third connecting part 131 is arranged on the water receiving tray part 130, and the fourth connecting part 151 is arranged on the volute tongue part 150, so that better connection can be achieved.

[0087] Please refer to Figures 4 to 7, in this embodiment, the first connecting portion 199 includes a first connecting frame 203. The first connecting frame 203 is connected to the air deflector mounting frame 190 and extends towards the water receiving tray portion 130. A first hook hole 205 is provided on the first connecting frame 203. The second connecting portion 201 includes a first connecting body 207 and a first hooking portion 209. One end of the first connecting body 207 is connected to the air deflector mounting frame 190, and the other end extends towards the volute tongue portion 150. The first hooking portion 209 is provided on the first connecting body 207 and extends in the first direction. The third connecting portion 131 includes a second connecting body 133 and a second hooking portion 135. One end of the second connecting body 133 is connected to the water receiving tray, and the other end extends towards the direction close to the air deflector mounting frame 190. The second hooking portion 135 is connected to the second connecting body 133 and extends in the second direction. The first direction is opposite to the second direction. The fourth connecting portion 151 includes a second connecting frame 153, and a second hook hole 155 is provided on the second connecting frame 153. When the air deflector mounting frame 190 moves along the first direction, the first hooking portion 209 can be hooked in the first hook hole 205, and the second hooking portion 135 can be hooked in the second hook hole 155.

[0088] In this embodiment, the air deflector mounting frame 190 is installed by setting hooks. In this way, the installation can be achieved by sliding the air deflector mounting frame 190, and the installation is more convenient.

[0089] During assembly, first align the first hooking portion 209 with the first hook, and align the second hooking portion 135 with the second hook hole 155. Then push the air deflector mounting frame 190 in the first direction. In this way, while the first hooking portion 209 can be hooked in the first hook hole 205, the second hooking portion 135 will be installed in the second hook hole 155. After installing the middle frame 170, the middle frame 170 will restrict the air deflector mounting frame 190 from moving in the second direction, thereby preventing it from falling off. This makes the assembly simpler.

[0090] Please refer to Figure 5 、 Figure 8 and Figure 9 , in this embodiment, a first card slot 211 is provided on the side of the air deflector mounting frame 190 close to the volute tongue portion 150. An avoidance notch 213 is provided on the upper side wall of the first card slot 211. The base 110 is provided with a clamping boss 111. The clamping boss 111 can be clamped in the first card slot through the avoidance notch 213, so that the end of the air deflector mounting frame abuts against the end of the volute tongue portion.

[0091] In this embodiment, by setting the cooperation of the clamping boss 111 and the first card slot, it can be ensured that the side of the air deflector mounting frame 190 close to the volute tongue portion 150 can be spliced with the volute tongue portion 150 relatively more tightly, thereby avoiding air volume loss and preventing the air at the air outlet 171 from flowing into the internal gap through the splicing gap between the air deflector mounting bracket and the volute tongue portion 150 to form condensation.

[0092] It should be noted that before the first hook - setting part and the second hook - setting part are connected, the clamping boss 111 is made to correspond to the avoidance notch 213. After the air deflector mounting bracket 190 is pushed to move, the clamping boss 111 will be clamped in the clamping groove, so as to realize the end - positioning of the air deflector mounting bracket 190, and thus abut against the end of the volute tongue part 150, so as to realize the sealing between the two and reduce the splicing gap.

[0093] In this embodiment, a clamping part 215 is provided at one end of the air deflector mounting bracket 190 close to the upper side of the air outlet 171. A second clamping groove 217 is provided on the clamping part 215. An inward first folding edge 173 is provided on the upper side of the middle frame 170 close to the air outlet 171. The first folding edge 173 is clamped in the second clamping groove 217.

[0094] Please refer to Figure 5 、 Figure 8 and Figure 9 , in this embodiment, by providing the clamping part 215 at the position of the air deflector mounting bracket 190 close to the upper side of the air outlet 171 and providing the second clamping groove 217 on the clamping part 215, the inward first folding edge 173 on the middle frame 170 can be relatively positioned and fixed, so as to realize the sealed installation between the air deflector mounting bracket 190 and the middle frame 170.

[0095] In this embodiment, a sealing rib 216 is provided at the position of the air deflector mounting bracket 190 close to the first folding edge 173. The sealing rib 216 is arranged along the length direction of the air deflector mounting bracket 190. The end of the first folding edge 173 abuts against the sealing rib 216. This can achieve sealing and prevent external air flow from flowing in.

[0096] In this embodiment, the indoor unit 100 further includes a panel 250. The panel 250 is installed on the outer side of the middle frame 170, and an inward second folding edge 251 is provided at one end of the panel 250 close to the upper side of the air outlet 171. The second folding edge 251 overlaps with the end of the air deflector mounting bracket 190, and the thickness of the second folding edge 251 gradually decreases, and it is inserted between the first folding edge 173 and the air deflector mounting bracket 190.

[0097] In this embodiment, the second folding edge 251 is provided on the panel 250, so that the second folding edge 251 overlaps with the end of the air deflector mounting bracket 190, so as to realize the splicing between the air deflector mounting bracket 190 and the panel 250 and reduce the splicing gap.

[0098] Further, a first lapping groove is formed at the end of the second hemming edge 251, and a second lapping groove is provided on the air deflector mounting bracket 190. When lapping the grooves, the ends of the first hemming edge 173 and the air deflector mounting bracket 190 become thinner, so that the end of the panel 250 laps on the second lapping groove, and the end of the air deflector mounting bracket 190 laps on the first lapping groove, achieving lapping between the two, thereby enabling better sealing.
