The connection between the blocking portion 3133 and the supporting portion 3132 is elastically connected, and when the water pressure sprayed from the nozzle reaches a predetermined pressure, the blocking portion 3133 is pushed away from the nozzle for spraying. When there is no water or insufficient water pressure, the blocking portion 3133 is restored to the initial position by the elastic connection to maintain the blocking state for the nozzle.

Further alternatively, the stopper 313 is made of an elastic material and integrally forms a fixing portion 3131, a supporting portion 3132 and a stopper 3133.

In this way, the condensed water filtered by the filter 35 is ensured to cover the water inlet B1 of the water suction pump 32, so that the water suction pump 32 is prevented from idling, and the condensed water in the water pan 50 is ensured to be efficiently conveyed to the water tank 33.

Optionally, the water outlet C2 of the water pan 50 is communicated with the water inlet A1 of the filter 35 through a pipeline 36; and/or the water outlet A2 of the filter 35 is communicated with the water inlet B1 of the water suction pump 32 through a pipeline 36; and/or the water outlet B2 of the water suction pump 32 is communicated with the liquid inlet D1 of the water tank 33 through a pipeline 36; and/or the liquid outlet D2 of the water tank 33 is communicated with the water inlet E1 of the booster pump 34 through a pipeline 36; and/or the water outlet E2 of the booster pump 34 is communicated with the spray head structure 31 through the pipeline 36. Therefore, the overall structural layout of the cleaning assembly 30 is planned, the space in the installation cavity 11 is reasonably utilized, and the overall structural design of the air conditioner is facilitated. The pipes 36 connected in series in turn are connected to form a water delivery pipe 311.

In the illustrated embodiment of the present application, the casing 10 is in a cubic shape, as shown in fig. 6 and 8, the condenser 40 extends along a length direction of the casing 10, and the air conditioner further includes an electrical box 70 disposed in the mounting cavity 11, wherein the electrical box 70 and the cleaning assembly 30 are respectively located at two ends of the condenser 40 in the length direction. Therefore, the electrical box 70 is far away from the cleaning assembly 30 as far as possible, so that the short circuit phenomenon caused by the contact of the electrical box 70 with water is avoided, and the working reliability of the air conditioner is improved.

It should be noted that: the electric box 70 is a motion control unit that controls air supply, cooling, and heating of the air conditioner and cleaning of the filter screen 20.

As shown in fig. 8 and 9 (the shower head structure is not provided with the stopper), the housing 10 is in a cubic shape, the condenser 40 is extended along the length direction of the housing 10, and the shower head structure 31 is installed at the upper part of the condenser 40 in the height direction; and the minimum mounting distance h3 between the head structure 31 and the condenser 40 in the height direction of the condenser 40 is 0mm or more and 100mm or less. In this way, a sufficient space is ensured between the condenser 40 and the casing 10 for mounting the head structure 31; and the problem that the condensed water sprayed by the spray head structure 31 cannot completely reach the filter screen 20 because the distance between the spray head structure 31 and the condenser 40 is too large, and further the cleaning effect of the filter screen 20 is influenced is avoided. It will be appreciated that the absence of a stopper in this schematic view does not affect the understanding of the present solution, and that the absence of a stopper clearly shows the nozzle orientation etc. of the spray head structure.

In order to ensure the all-round cleaning effect of the filter screen 20, optionally, the spray head structures 31 are multiple, and the multiple spray head structures 31 are sequentially arranged at intervals along the length direction of the casing 10. In the present embodiment, as shown in fig. 8, the nozzle structures 31 are two that are provided at intervals along the length direction of the casing 10.

In the present embodiment, the housing 10 is cube-shaped, the condenser 40 is extended along the length direction of the housing 10, the working position of the filter screen 20 is located at the upper part of the height direction of the condenser 40, and the cleaning position of the filter screen 20 is located at one side of the thickness direction of the condenser 40; and a minimum position distance h4 between the filter net 20 and the condenser 40 in the thickness direction of the condenser 40 is 1mm or more and 100mm or less. Thus, by optimizing the position relationship between the filter screen 20 and the condenser 40, the problem that the cleaning effect of the filter screen 20 is influenced because the condensed water sprayed by the spray head structure 31 does not have enough impact force when reaching the filter screen 20 due to the fact that the distance between the filter screen 20 and the condenser 40 is too far is avoided; meanwhile, the phenomenon that the distance between the filter screen 20 and the condenser 40 is too small, so that the impact force of the condensed water sprayed by the spray head structure 31 reaching the filter screen 20 is too large, the dirt on the filter screen 20 is sputtered to the condenser 40, and secondary pollution occurs is avoided.

Optionally, the showerhead structure 31 is a wide angle showerhead.

In the present embodiment, the filter net 20 is moved between the working position and the cleaning position in a rotating manner; and the rotation angle of the spray head structure 31 between the working position and the cleaning position is greater than 0 degree and less than or equal to 90 degrees. Specifically, be provided with filter screen actuating mechanism in the installation cavity 11, filter screen actuating mechanism includes the installation body, and filter screen 20 rotationally sets up on the installation body, and filter screen 20 rotates with motor gear drive's mode. The filter screen driving mechanism can ensure that the filter screen 20 runs at a higher speed, because the water consumption for cleaning the filter screen 20 mainly depends on the water spraying time of the spray head structure 31, the faster the filter screen 20 is, the less the water consumption is; to ensure minimum water consumption, the filter screen should be moved at a faster speed.

Alternatively, the filter screens 20 may be stacked in plurality, and each filter screen 20 may be driven by a separate motor to ensure sufficient drive torque during movement of the filter screen 20 at a faster rate.

As shown in fig. 10 and 11, when the filter screen 20 is located at the working position, the filter screen 20 is parallel to the inner wall surface of the housing 10 and located at the air inlet 12; when the filter net 20 is located at the cleaning position, the filter net 20 is parallel to the inner wall surface of the housing 10 and located at the front panel 13 of the housing 10. In this embodiment, the rotation angle of the filter net 20 from the working position to the cleaning position is 90 degrees; namely, the filter screen 20 is in a horizontal state when in a working position, and the filter screen 20 is in a vertical state when in a cleaning position; when the filter screen 20 is in the cleaning position, the nozzle structure 31 is perpendicular to the filter screen 20 to ensure that the filter screen 20 is sufficiently cleaned.
