[0031] As Figures 1-5 shown, the present utility model provides an indoor unit structure, which includes an indoor unit housing 10 and a second water receiving tray 200. A first water receiving tray 100 is arranged inside the indoor unit housing 10. The second water receiving tray 200 is located outside the indoor unit housing 10 and is detachably connected to the indoor unit housing 10. When the second water receiving tray 200 is connected to the indoor unit housing 10, the water inlet of the second water receiving tray 200 is communicated with the water outlet of the first water receiving tray 100.

[0032] Wherein, when the second water receiving tray 200 is connected to the outdoor unit housing, the second water receiving tray 200 is communicated with the first water receiving tray 100, so that after the first water receiving tray 100 receives the condensed water of various components such as the evaporator in the indoor unit, the condensed water can flow into the second water receiving tray 200, and at the same time, the dirt in the first water receiving tray 100 also flows into the second water receiving tray 200 with the condensed water. That is, through the cooperation of the first water receiving tray 100 and the second water receiving tray 200, the condensed water and dirt in the indoor unit are discharged outside the indoor unit.

[0033] It is understandable that with the above settings, the condensed water in structures such as the evaporator in the indoor unit and the dirt in the first water receiving tray 100 flow downstream from the first water receiving tray 100 into the second water receiving tray 200. Since the second water receiving tray 200 is arranged outside the indoor unit housing 10, the second water receiving tray 200 can be cleaned without removing the ceiling, improving the cleaning efficiency and convenience of the water receiving tray of the indoor unit.

[0034] The detachable connection methods between the second water receiving tray 200 and the outdoor unit housing include, but are not limited to, plug connection, snap connection, screw connection, etc.

[0035] Meanwhile, in order to enable the first water receiving tray 100 and the second water receiving tray 200 to be naturally connected when the second water receiving tray 200 is connected to the outdoor unit housing, the side wall of the first water receiving tray 100 close to the outdoor unit housing is usually arranged, and the second water receiving tray 200 is also connected to the corresponding position on the side wall of the outdoor unit housing.

[0036] Generally, in order to enable the condensed water in the first water receiving tray 100 to flow into the second water receiving tray 200 under the action of gravity, the installation position of the first water receiving tray 100 can be relatively higher than that of the second water receiving tray 200. For example, the distance between the bottom wall of the first water receiving tray 100 and the bottom wall of the indoor unit housing 10 is 5 cm, and the bottom wall of the second water receiving tray 200 is flush with the bottom wall of the indoor unit housing 10.

[0037] Furthermore, in order to enable the condensed water in the first water receiving tray 100 to flow into the second water receiving tray 200 better, the bottom wall of the first water receiving tray 100 is inclined, and the water outlet of the first water receiving tray 100 is arranged on the relatively lower side.

[0038] Furthermore, there is a drop between the water outlet of the first water receiving tray 100 and the water inlet of the second water receiving tray 200. For example, the position of the first water receiving tray 100 is relatively higher than that of the second water receiving tray 200, and at the same time, the pipe connecting the two is inclined.

[0039] In some embodiments, a pumping component is arranged in the second water receiving tray 200. The pumping component includes a water pump 300 and a first return pipe 310. One end of the first return pipe 310 is communicated with the water outlet of the water pump 300, and the other end of the first return pipe 310 is arranged in the second water receiving tray 200 and is arranged towards the water inlet of the water pump 300.

[0040] It is understandable that by arranging the pumping component on the second water receiving tray 200 and making the second water receiving tray 200 detachably connected to the outdoor unit housing, when the pumping component needs to be cleaned, the second water receiving tray 200 can be directly removed, simplifying the conventional cleaning and maintenance steps and improving the convenience of repairing and cleaning the pumping component.

[0041] Generally, by arranging a water pump 300 in the second water receiving tray 200 and connecting an external water pipe to the water outlet of the water pump 300, the condensed water in the second water receiving tray 200 can be used to flush structures such as the air return opening, filter screen, and evaporator of the indoor unit. After connecting the first return water pipe 310 to the water outlet of the water pump 300 and orienting the water outlet end of the first return water pipe 310 towards the water inlet of the water pump 300, it is possible to flush when the water inlet of the water pump 300 is blocked by dust and eliminate the blockage.

[0042] For example, a three-way valve is connected to the water outlet of the water pump 300. One valve port of the three-way valve is connected to the water outlet of the water pump 300, the second valve port of the three-way valve is communicated with the water inlet of the first return water pipe 310, and the third valve port of the three-way valve is communicated with the external water pipe.

[0043] In some embodiments, the water pumping assembly further includes a first water outlet pipe 320. One end of the first water outlet pipe 320 is communicated with the water outlet of the water pump 300, and the other end of the first water outlet pipe 320 extends out of the second water receiving tray 200;

[0044] The water inlet end of the first return water pipe 310 is connected to one side of the first water outlet pipe 320 and is communicated with the first water outlet pipe 320.

[0045] It can be understood that by connecting the first water outlet pipe 320 to the water outlet of the water pump 300 and directly connecting the external water pipe to the first water outlet pipe 320, the components of the indoor unit can be flushed. At the same time, by connecting the first return water pipe 310 to the side of the first water outlet pipe 320 and making them communicate, when the water pump 300 works, the first return water pipe 310 can flush the water inlet of the water pump 300 to avoid dust blockage of the water inlet.

[0046] In some embodiments, a plurality of guide ribs are arranged in the second water receiving tray 200. The plurality of guide ribs cooperate with the side wall of the second water receiving tray 200 to form a guide channel 210, so that the water flowing into the second water receiving tray 200 from the water inlet of the second water receiving tray 200 flows along the side wall of the second water receiving tray 200 to the water pumping assembly.

[0047] Among them, the plurality of guide ribs are arranged on the bottom wall of the second water receiving tray 200. The plurality of guide ribs cooperate with the side wall of the second water receiving tray 200 to form a guide channel 210, which can avoid the disorderly flow of the condensed water flowing in from the water inlet of the second water receiving tray 200 and make it flow orderly to the water pumping assembly (water pump 300), so as to facilitate the utilization of the water pumping assembly.

[0048] In addition, the flow channel formed by the cooperation of the guide ribs and the side wall enables the condensed water entering the second water receiving tray 200 to flow along the side wall, which can increase the flow path of the condenser in the water receiving tray. Furthermore, the dust in the condensed water can precipitate in the guide channel 210, thus avoiding its precipitation near the water pumping assembly.

[0049] Generally, the pumping assembly is disposed in the middle of the second water receiving tray 200, and the diversion channel 210 is arranged around the pumping assembly.

[0050] In some embodiments, at least one diversion rib is disposed between the pumping assembly and the water inlet of the second water receiving tray 200.

[0051] That is, by arranging diversion ribs between the water inlet of the second water receiving tray 200 and the pumping assembly, the condensed water at the water inlet is prevented from flowing directly to the pumping assembly, so as to avoid dust deposition at the pumping assembly.

[0052] For example, the second water receiving tray 200 includes a bottom wall and a first side wall 201, a second side wall 202, a third side wall 203, and a fourth side wall 204 that are sequentially arranged around the bottom wall. The pumping assembly is disposed in the middle of the second water receiving tray 200. The water inlet of the second water receiving tray 200 is disposed opposite to the pumping assembly and is located on the first side wall 201. The second water receiving tray 200 has a first diversion rib 211, and the first diversion rib 211 is disposed between the pumping assembly and the first side wall 201. The second water receiving tray 200 further has a second diversion rib 212, and the second diversion rib 212 is disposed close to the fourth side wall 204. The first diversion rib 211, the second diversion rib 212, and the first side wall 201 and the fourth side wall 204 form a diversion channel 210, so that the condensed water flowing in from the water inlet of the second water receiving tray 200 flows to the pumping assembly after turning twice at least.

[0053] That is, the diversion channel 210 formed by the cooperation of multiple diversion ribs and the side walls of the second water receiving tray 200 in the second water receiving tray 200 has at least two turning points. By setting the turns multiple times, the dust in the condensed water is deposited at the turning points, preventing it from concentrating near the pumping assembly.

[0054] In some embodiments, the second water receiving tray 200 further includes a first water outlet and a second water outlet. Both the first water outlet and the second water outlet are disposed on the side wall of the second water receiving tray 200, and the second water outlet is located between the first water outlet and the bottom wall of the second water receiving tray 200.

[0055] Among them, the water inlet, the first water outlet, and the second water outlet of the second water receiving tray 200 are all disposed on the side wall of the second water receiving tray 200. In order to enable the condensed water to drain out of the second water receiving tray 200 under the action of gravity, the installation positions of the first water outlet and the second water outlet are both lower than the water inlet of the second water receiving tray 200. At the same time, the second water outlet is located between the first water outlet and the bottom wall of the second water receiving tray 200. The first water outlet serves as a gravity water outlet, and the second water outlet serves as a sewage outlet.

[0056] In some embodiments, the second water outlet can also be directly disposed on the bottom wall of the second water receiving tray 200.

[0057] In some embodiments, a first water inlet portion 240 is provided at the water inlet of the second water receiving tray 200. The first water inlet portion 240 can be plugged into the water outlet of the outdoor unit housing, so that the first water receiving tray 100 is communicated with the second water receiving tray 200. That is, while the first water inlet portion 240 communicates the first water receiving tray 100 with the second water receiving tray 200, it also improves the connection stability between the second water receiving tray 200 and the outdoor unit housing. The first water inlet portion 240 can be a pipe.

[0058] In some embodiments, a first water outlet portion 220 is provided at the first water outlet. The first water outlet portion 220 can be a pipe.

[0059] In some embodiments, a second water outlet portion 230 is provided at the second water outlet. The second water outlet portion 230 can be a pipe.

[0060] In some embodiments, a plug-in member 250 is provided on one side of the second water receiving tray 200, and a plug-in groove is provided on the indoor unit housing 10. The plug-in member 250 is plugged into the plug-in groove to connect the second water receiving tray 200 to the indoor unit housing 10.

[0061] That is, the second water receiving tray 200 is plugged into the indoor unit housing 10 through the plug-in member 250 and the plug-in groove, realizing the detachable connection between the second water receiving tray 200 and the indoor unit housing 10.

[0062] Generally, in order to match the thickness of the indoor unit housing 10, the plug-in member 250 is usually provided in a sheet-like structure.

[0063] In some embodiments, a plurality of anti-slip protrusions 251 are provided on the plug-in member 250.

[0064] That is, by providing the anti-slip protrusions 251 on the plug-in member 250, the connection stability between the plug-in member 250 and the plug-in groove can be improved.

[0065] In some embodiments, the outdoor unit structure further includes a water receiving tray cover 800. The water receiving tray cover 800 is covered on the second water receiving tray 200 and cooperates with the second water receiving tray 200 to form a receiving space.

[0066] It can be understood that on the one hand, the water receiving tray cover 800 can form a shield for the second water receiving tray 200 to prevent impurities from falling into the second water receiving tray 200, and on the other hand, it can also protect components such as the water pump 300 provided in the receiving space.

[0067] Generally, the water receiving tray cover 800 and the second water receiving tray can be connected by detachable connection methods such as buckles and screws.

[0068] In some embodiments, the present utility model further provides an air duct machine, which includes the indoor unit structure described above. Since this air duct machine includes the indoor unit structure of the above embodiments or combined embodiments, it thus has at least some or all of the beneficial effects of the above indoor unit structure, which will not be elaborated here one by one.

[0069] The above are only the optional embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model under the application concept of the present utility model, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
