Optionally, the water inlet 101 is disposed at a position lower than the water outlet 102. When the setting position of the water inlet 101 is lower than that of the water outlet 102, the condensed water must flow from the water inlet 101 to the water outlet 102 along the hollow pipeline, and due to the action of gravity in the flowing process, the condensed water must be completely filled in the hollow pipeline with the lower position, so that the condensed water can continue to flow upwards, and the condensed water cannot flow out from the water outlet 102 until the whole pipeline of the air return grid 1 is completely filled with the condensed water.

Like this, the comdenstion water can flow from low to high along return air grid 1 pipeline, the comdenstion water can be full of return air grid 1 pipeline completely, make no gas in the return air grid 1 pipeline, make the temperature of return air grid 1 more be close to the temperature of comdenstion water, and then increase the temperature difference between return air grid 1 and the air that flows through return air inlet 11, thereby make return air grid subassembly and the air that flows through return air inlet 11 fully carry out the heat exchange, make full use of the cold volume of comdenstion water, and then improve the utilization degree of comdenstion water, better reduction air conditioner's energy consumption and the refrigerating capacity that improves the air conditioner.

The other end of the drain pipe extends to the outside of the air conditioner and comprises a through hole, and the other end of the drain pipe extends to the through hole on the shell of the air conditioner and does not exceed the through hole. Of course, the other end of the drain pipe may extend outside the air conditioner, that is, the drain pipe may leak out of a portion of the air conditioner. Illustratively, as shown in fig. 3, a through hole is formed in the housing of the air conditioner, one end of the drain pipe is communicated with the water outlet of the water pump, and the other end of the drain pipe extends to the through hole in the housing of the air conditioner, so that water can be drained out of the air conditioner.

Therefore, by the design that the water outlet 102 is connected with the water drainage pipe 5, condensed water after heat exchange in the air return grid 1 can be drained in time, the precooling efficiency of the air return grid 1 is improved, and the refrigerating efficiency of the air conditioner is further improved.

Referring to fig. 2, an embodiment of the present disclosure provides an air conditioner including an indoor unit. The indoor unit comprises a shell 6, an evaporator 7, a fan 9, a condensed water pan 8 and a return air grid assembly for the air conditioner in the embodiment.

The indoor unit of the air conditioner may be a wall-mounted indoor unit, a drop-type indoor unit, an embedded indoor unit, and a cassette indoor unit (a duct unit), and for example, the present embodiment is described by taking the wall-mounted indoor unit as an example, and it can be understood that the indoor unit of the air conditioner includes, but is not limited to, a wall-mounted indoor unit.

The shape of the shell 6 can be a cuboid, a cube or an irregular three-dimensional structure, and it can be understood that the shape of the shell 6 is not unique and can be changed according to the use requirement.

An air return opening 11 is formed in one side of the indoor unit shell 6, and the air return opening 11 of the indoor unit is used for returning air. The traditional energy-saving air conditioner can suck a part of indoor air and a part of outdoor air to be mixed and refrigerated and then blow out the air when refrigerating, and when the indoor load is fixed, the amount of cold air to be sent indoors is fixed. Because the indoor air is generally lower in temperature in summer compared with fresh air (outdoor air), some air is returned into the air conditioning box by the air return opening 11, mixed with a small amount of fresh air and made into cold air to be sent into the room. Compared with the method of completely producing cold air by using fresh air, the method can effectively save energy.

The other side of the indoor unit casing 6 is provided with an air outlet 10, and air returned from the air return port 11 after temperature reduction treatment is discharged out of the casing 6 and blown to the indoor.

The evaporator 7 is arranged in the middle of the shell 6, and the fan 9 is arranged on one side of the evaporator 7, which is far away from the air return opening 11, in the air conditioner. The air conditioner evaporator 7 is used for achieving the purpose of refrigeration by utilizing the fact that liquid low-temperature refrigerant is easy to evaporate under low pressure, is converted into steam and absorbs heat of cooled media. The evaporator 7 uses the fan 9 to force the indoor air to flow through the cooling calandria in the shell 6 for heat exchange, so as to cool the air, thereby achieving the purpose of reducing the room temperature.

The condensed water pan 8 is arranged below the evaporator 7, because the evaporator 7 absorbs heat of indoor air, condensed water is extremely easy to form in the precooling of the indoor air and is attached to the evaporator 7, small water drops can be formed after a long time, the condensed water flows down from the evaporator 7, the condensed water pan 8 can be arranged to effectively prevent the condensed water from flowing to other parts of the shell 6, and then the possibility that the condensed water affects the normal work of other parts is reduced.

The return air grid assembly for the air conditioner in the above-mentioned embodiment is suitable for being arranged at the return air inlet 11 of the indoor unit, and the water inlet 101 of the return air grid assembly for the air conditioner is communicated with the condensed water pan 8.

By adopting the air conditioner in the above embodiment, when the air conditioner is refrigerating, under the action of the water pump 3, the condensed water is discharged after passing through the condensed water pan connecting pipe 2, the S-shaped flow passage, the water pump connecting pipe 4, the water pump 3 and the water discharge pipe 5 in sequence; the temperature of the condensed water is about 15 ℃ when the water pan is formed, the condensed water can quickly reach the S-shaped flow channel and is fully distributed in the S-shaped flow channel due to the action of the water pump 3, the heat exchange performance of the pipe of the S-shaped flow channel is good, the surface temperature of the pipe of the S-shaped flow channel is reduced at the moment, the return air passes through the gap of the S-shaped flow channel and is cooled, and therefore the effect of return air precooling is achieved.

Optionally, the position of the return air grid assembly water inlet 101 is lower than the position of the condensed water pan 8. When the setting position of the water inlet 101 of the return air grid assembly is lower than the setting position of the condensed water pan 8 of the indoor unit, the condensed water pan 8 of the indoor unit is communicated with the water inlet 101 of the return air grid assembly, so that the condensed water in the condensed water pan 8 can flow into the return air grid assembly from the condensed water pan 8 along the pipeline under the action of gravity, and the water pump 3 is not started to enable the condensed water to flow into the return air grid assembly.

For example, as shown in fig. 3, the water inlet 101 of the return air grid assembly is arranged at a position lower than the condensate water pan 8, so that water can automatically flow to the water inlet 101, the cold energy of the condensate water can be fully utilized, and the situations that the placing time is too long and the cold energy of the condensate water is reduced are avoided.

Therefore, the design that the setting position of the water inlet 101 of the return air grid assembly is lower than the setting position of the condensed water pan 8 can enable the condensed water to automatically flow to the water inlet 101 under the condition that the water pump 3 is not started, and further the cold quantity of the condensed water is fully stored and utilized.
