Referring to fig. 1 to 4, an embodiment of the present disclosure provides an air conditioner, which includes a housing 100, an air inlet 200 configured in the housing 100, and a filter screen 300 disposed at the air inlet 200, and further includes a spraying system for the air conditioner, where the spraying system for the air conditioner includes a spraying pipe 510, a water storage box 520, a bidirectional water pump 530, an outlet pipe 540, and an inlet pipe 550, where the spraying pipe 510 is fixed to the air conditioner and is used for spraying a cleaning solution to clean the filter screen 300; the water storage box 520 stores washing water; the bidirectional water pump 530 comprises a first interface and a second interface, and the first interface is communicated with the water storage box 520; one end of the water outlet pipeline 540 is connected to the second connector of the bidirectional water pump 530, and the other end is connected to the spray pipe 510; one end of the water inlet pipe 550 is connected to the second port of the bidirectional water pump 530, and the other end of the water inlet pipe extends to the water receiving tray 400, when the bidirectional water pump 530 is in the first pumping direction, the water in the water receiving tray 400 is pumped into the water storage box 520 through the water inlet pipe 550, and when the bidirectional water pump 530 is in the second pumping direction, the water in the water storage box 520 is pumped into the shower pipe 510 through the water outlet pipe 540.

In the disclosed embodiment, a spray system for an air conditioner is provided to clean the screen 300. The spraying system provided by the embodiment of the disclosure is applied to an air conditioner provided with an air inlet 200 and a filter screen 300 arranged at the air inlet 200. The spraying system can be applied to indoor units of air conditioners and can also be applied to outdoor units of air conditioners. The shower pipe 510 may be tubular or box-packed, and its shape may be set according to the specific structure of the air conditioner, and is not limited specifically herein. The shower pipe 510 has one or more water spray holes to enable water spray cleaning of the filter screen 300, and the form thereof is not particularly limited. The water storage box 520 stores washing water. The washing water is water used to clean the filter 300, and may be general domestic water or water mixed with a certain detergent or surfactant. The bi-directional water pump 530 means that the direction of water flow in its pump body can be controllably changed. The bidirectional water pump 530 comprises a first interface and a second interface, and when the bidirectional water pump 530 is in the first pumping direction, the flow direction of water in the water pump is from the second interface to the first interface; when the bidirectional water pump 530 is in the second pumping direction, the flow of water in the water pump is from the first port to the second port.

When the outdoor unit of the air conditioner is used as an evaporator, the surface temperature of the heat exchanger of the outdoor unit is relatively low, and the water pan 400 of the outdoor unit is likely to generate condensed water. When the indoor unit of the air conditioner is used as a condenser, the drip pan 400 of the indoor unit easily generates condensed water. The condensed water in the water pan 400 is collected into the water storage box 520 through the bidirectional water pump 530, so that water can be saved. Water generated by spray cleaning of the filter screen 300 may also be re-collected into the water storage box 520. The water replenishing to the water storage box 520 and the water supplying to the spray pipe 510 are realized through the bidirectional water pump 530, the structure of the spray system is simplified, the production and manufacturing cost is saved, and the water resource is also saved.

Alternatively, the spraying system is applied to an indoor unit of an air conditioner, and the other end of the water inlet pipe 550 extends to the water pan 400 of the indoor unit of the air conditioner and/or the water pan 400 of the outdoor unit of the air conditioner.

Alternatively, the spraying system is applied to an outdoor unit of an air conditioner, and the other end of the water inlet pipe 550 extends to the water pan 400 of the indoor unit of the air conditioner and/or the water pan 400 of the outdoor unit of the air conditioner.

Optionally, the air conditioner further includes a screen track disposed at the air inlet 200, the screen 300 is slidably disposed at the screen track, and a driving assembly 600 for driving the screen 300 to move between a first position for filtering air and a second position away from the air inlet 200.

The shape of the filter screen 300 corresponds to the shape of the intake vent 200. The water outlet position of the shower pipe 510 is located at a position staggered from the air inlet 200, that is, the direction of the outlet water of the nozzle corresponds to the solid side wall of the air conditioner. When the filter screen 300 is in the first position for filtering air, the filter screen 300 covers the air inlet 200 to filter the air entering the air conditioner through the air inlet 200. When the filter 300 is at the second position, the filter 300 leaves the air inlet 200. Therefore, the situation that cleaning water is blown from the air inlet 200 when the filter screen 300 is cleaned can be avoided, and secondary pollution to the environment where the air conditioner is located when the filter screen 300 is cleaned is avoided. The filter track is disposed at the intake vent 200 to facilitate movement of the filter 300 between the first position and the second position. The drive assembly 600 is used to drive the screen 300 between the first and second positions, thereby enabling automatic cleaning of the screen 300.

Optionally, the screen track is horizontally disposed, the screen 300 moves horizontally relative to the air outlet, the shower pipe is fixed in position, and the screen 300 is cleaned by spraying cleaning water in the moving process of the screen 300.

The spray area of the spray pipes 510 in the arrangement form does not need to be too large, only one row of the filter screen 300 perpendicular to the moving direction needs to be covered, the movable spray pipes 510 do not need to be arranged, and the filter screen 300 can be cleaned in all directions by the fixed spray pipes 510 and the moving filter screen 300.

Optionally, the filter screen track is vertically arranged, the filter screen 300 moves up and down relative to the air outlet, the position of the spray pipe is fixed, and spray water is sprayed out to clean the filter screen 300 in the moving process of the filter screen 300.

Such an arrangement may also allow for all-around cleaning of screen 300.

Preferably, the shower is located below the outlet. Therefore, water sprayed to the filter screen 300 by the spray pipe 510 flows into the water receiving tray 400 after washing the filter screen 300, and the filter screen 300 is not easy to bring washing water out from the air inlet 200 in the upward movement process, so that secondary pollution to the environment where the air conditioner is located when the filter screen 300 is washed is effectively avoided.

Optionally, the driving assembly 600 includes a rack 610, a gear 620 and a driving motor 630, wherein the rack 610 is fixed to the filter screen 300; a gear 620 fixed to the housing 100, the gear 620 being engaged with the rack 610; and the driving motor 630 is in transmission connection with the gear 620.

By the gear 620 being fixed, it may be meant that the position of the gear 620 remains fixed relative to the housing 100, the gear 620 itself being a rotatable component. The driving motor 630 is drivingly connected to the gear 620, and the position of the driving motor 630 is also kept fixed relative to the housing 100. For example, the driving motor 630 may be fixed to the housing 100, and the gear 620 may be fixed to an output shaft of the driving motor 630. The drive may also be drivingly connected to the gear 620 via one or more reduction gears 620. When the screen 300 is cleaned, the screen 300 moves at a relatively slow speed. Such a configuration allows a driving motor 630 with smaller power to drive the movement of the filter screen 300, which not only reduces the space occupied by the motor, but also reduces the manufacturing cost.

Alternatively, the screen track is horizontally disposed, and the shower pipe 510 includes a plurality of nozzles disposed from top to bottom corresponding to the screen 300. The plurality of nozzles are arranged from top to bottom corresponding to the screen 300, and the plurality of nozzles are arranged in a row. Thus, as screen 300 moves horizontally along the screen track, the portion of screen 300 passing through the nozzles is washed. This may improve the cleaning effect of the filter screen 300.

Optionally, the inlet conduit 550 and the outlet conduit 540 are each provided with a control valve. The bi-directional pump 530 has a first port and a second port, and when the bi-directional pump 530 is in a first pumping direction, the water in the drip tray 400 is pumped into the water storage box 520 through the water inlet pipe 550. When the bi-directional pump 530 is in the second pumping direction, the water in the water storage box 520 is pumped to the shower pipe 510 through the outlet pipe 540. The inlet conduit 550 and the outlet conduit 540 share a single bi-directional water pump 530, and control valves are provided in the inlet conduit 550 and the outlet conduit 540 to avoid interference between the inlet conduit 550 and the outlet conduit 540. When water enters the water inlet pipe 550, the control valve of the water inlet pipe 550 is opened, and the control valve of the water outlet pipe 540 is closed; when the outlet conduit 540 is discharging, the control valve of the outlet conduit 540 is opened and the control valve of the inlet conduit 550 is closed. Therefore, mutual interference between the water inlet pipeline 550 and the water outlet pipeline 540 can be effectively avoided, and the stability of cleaning control of the filter screen 300 is improved. When the water in the water storage box 520 needs to be drained, the control valve of the water inlet pipe 550 is opened, the control valve of the water outlet pipe 540 is closed, and the pumping direction of the bidirectional water pump 530 is the second pumping direction, so that the water in the water storage box 520 is drained to the water receiving tray 400 along the water inlet pipe 550.

Optionally, the air conditioner is further provided with an optical sensor, and the optical sensor includes an optical emitter and an optical receiver, which are respectively located at both sides of the filter screen 300. The signal from the optical transmitter is attenuated by the screen 300 and received by the optical receiver. The degree of filth blockage of the filter screen 300 can be judged according to the degree of signal attenuation, and further, whether the filter screen 300 needs to be cleaned is judged. The arrangement mode can enable the air conditioner to realize self-checking of the filth blockage condition of the filter screen 300, and the air conditioner is more intelligent.

Optionally, the vertical direction of the light sensor is multiple, and the multiple light sensors are disposed at different positions corresponding to the filter screen 300. The filth blockage condition of the filter screen 300 is judged through the plurality of optical sensors, so that the judgment result is more accurate.

Optionally, the air conditioner is further provided with an air volume sensor arranged at an air blowing port of the air conditioner. When the filter screen 300 of the air conditioner is dirty and blocked, the air inlet effect of the air conditioner can be influenced, and the air outlet intensity of the air conditioner is further influenced. The air outlet intensity of the air conditioner is obtained through the air volume sensor, the numerical value of the air outlet intensity is compared with the reference value of the air outlet intensity when the filter screen 300 is clean, and the filth blockage condition of the air conditioner filter screen 300 can be judged. Due to the arrangement mode, the air conditioner can perform self-checking on the filth blockage condition of the filter screen 300, and the air conditioner is more intelligent.
