And the indoor heat exchanger 120 is configured such that the air flowing in from the intake vent 111 flows through the indoor heat exchanger 120 to sufficiently cool/heat the air. The fan 150 is a cross flow fan for drawing the outside air from the air inlet 111 toward the indoor heat exchanger 120 and forcing the air cooled/heated by the indoor heat exchanger 120 to be blown out from the air outlet 113.
With reference to fig. 2, in some embodiments of the present invention, an air deflector is installed on the body 110 and located at the air outlet 113 to guide the direction of the cold/hot air blowing at the air outlet 113.
The air conditioning indoor unit 100 will be further described below with reference to the cooling function of the air conditioning indoor unit 100. Of course, those skilled in the art can configure the indoor unit 100 of the air conditioner of the present invention to have only a cooling function and not a heating function, as needed.
Returning to continue with fig. 1, the capillary tube 130 is fluidly connected to the inline tube assembly 300 by its inlet end, and the capillary tube 130 is fluidly connected to the inlet of the indoor heat exchanger 120 by its outlet end.

For example, the refrigerant inlet pipe is connected in series between the indoor heat exchanger 120 and the capillary tube 130, or the refrigerant inlet pipe is connected in series on a side of the capillary tube 130 away from the indoor heat exchanger 120.
Similarly, if necessary, a refrigerant outlet pipe may be disposed in the air conditioning indoor unit 100, and the refrigerant outlet pipe may be fluidly connected to the outlet of the indoor heat exchanger 120 and the on-line pipe assembly 300, and may be connected in series to the muffler pipe 140. For example, the refrigerant outlet pipe is connected in series between the indoor heat exchanger 120 and the muffler pipe 140, or the refrigerant outlet pipe is connected in series on a side of the muffler pipe 140 away from the indoor heat exchanger 120.
It should be noted that, in the description of the present invention, the inlet of the indoor heat exchanger 120 and the outlet of the indoor heat exchanger 120 are the inlet and the outlet of the indoor heat exchanger 120 when the indoor unit 100 of the air conditioner is cooling.

In addition, in other embodiments of the present invention, the capillary tube 130 may be configured as any other feasible pressure reducing component, such as an electronic expansion valve, a throttle valve, etc., as required by those skilled in the art.
With continued reference to fig. 1, in some embodiments of the present invention, the capillary tube 130 is wound around the outside of the muffler 140. Preferably, the capillary tube 130 is wound around the muffler 140 with its upstream tube segment.

Optionally, the first tube segment 311 and the second tube segment 312 are detachably connected to the filter 400, so that the worker can select or replace the first tube segment 311 and the second tube segment 312 with proper lengths according to actual conditions.
Further, in some embodiments of the present invention, in the extending direction of the air inlet pipe 310, the distance between the filter 400 and the wall is not greater than 20cm, so as to ensure that the filter 400 is located outdoors, and can filter all the liquid refrigerants outside the room, thereby not only ensuring the filtering effect of the filter 400 on the refrigerants, but also preventing the noise generated when the refrigerants flow in the filter 400 from being transmitted indoors and affecting users.
Preferably, the filter 400 is aligned with the mounting hole 510 of the wall 500 through which the inline pipe assembly 300 passes. It is further preferable that the filter 400 abuts against the outer port of the mounting hole 510 to shield the outer port of the mounting hole 510 by the filter 400.
Further alternatively, a sound insulating member is provided between the filter 400 and the mounting hole 510, and the sound insulating member abuts against the outer ports of the filter 400 and the mounting hole 510, respectively. The sound insulating member may be any feasible member or material, such as an annular rubber pad, a silicone pad, or a foaming agent.
As shown in fig. 3, in some embodiments of the present invention, the filter 400 includes a housing 410, two filters 420 and a desiccant 430, wherein both the two filters 420 and the desiccant 430 are disposed within the housing 410, and the desiccant 430 is located between the two filters 420. In some embodiments of the present invention, the filter screen 420 is mainly used for filtering impurities in the refrigerant; the desiccant 430 is mainly used to absorb moisture in the refrigerant and dry the refrigerant.
As shown in fig. 4, in other embodiments of the present invention, the filter 400 includes only a housing 410 and a filter screen 420, without a desiccant 430. Further, the filter 420 may be configured in any feasible shape such as a cup shape, a bowl shape, etc. And the filter screen 420 may be replaced by any other feasible filter material, such as porous ceramic.
In addition, in other embodiments of the present invention, a person skilled in the art may also set the filter 400 as a hollow cylindrical structure as a whole, so that the air return pipe 320 passes through the center hole of the filter 400, thereby enabling the filter 400 to be coaxial with the mounting hole 510 on the wall 500. Specifically, the case 410 is provided as a hollow columnar structure as a whole, and an annular cavity is formed in the case 410. Also, the filter net 420 is provided in a ring shape, so that the filter net is placed in the ring-shaped cavity.
Further, although not shown in the drawings, in the present invention, the outdoor unit 200 includes a compressor, an outdoor heat exchanger and a fan for radiating heat from the outdoor heat exchanger, so that the outdoor unit 200 is connected to the air inlet pipe 310 through the outdoor heat exchanger and connected to the air return pipe 320 through the compressor.
Based on the foregoing description, it can be understood by those skilled in the art that the air conditioner of the present invention reduces the attenuation of the cooling capacity when the air conditioner is used for cooling in a high temperature environment, and improves the cooling efficiency; meanwhile, the filter 400 is arranged at the position close to the wall 500 outdoors, so that noise generated when the refrigerant flows through the filter 400 is prevented from being transmitted indoors, and the use experience of a user is improved.
It should be noted that, in the description of the present invention, if there is no special description, the drift diameter of other pipelines is greater than that of the capillary, and it is considered that other pipelines do not have throttling and pressure reducing effects on the refrigerant.
So far, the technical solution of the present invention has been described in connection with the foregoing embodiments, but it is easily understood by those skilled in the art that the scope of the present invention is not limited to these specific embodiments. Without deviating from the technical principle of the present invention, those skilled in the art can split and combine the technical solutions in the above embodiments, and also can make equivalent changes or substitutions for the related technical features, and any changes, equivalent substitutions, improvements, etc. made within the technical concept and/or technical principle of the present invention will fall within the protection scope of the present invention.
