The water spray device is arranged at The indoor heat exchanger 1 is above, and water is sprayed to the indoor heat exchanger 1. The water receiving tray 2 is set under the indoor heat exchanger 1 to receive the water flowing down from the indoor heat exchanger 1 and deliver it to the water storage tank 3. .

In the air conditioner of the present application, the water spray device is installed above the indoor heat exchanger 1, and the indoor heat exchanger 1 is sprayed with water. The water flow along the fins of the indoor heat exchanger 1 forms a dust-removing water curtain. The additional water curtain device can use the structure of the air conditioner itself to form a water curtain, the structure is simpler, the design cost is lower, and it can play a good dust removal effect.

Since the water receiving pan 2 is arranged below the indoor heat exchanger 1 and is connected to the water storage tank 3, it can recover the water flowing down the indoor heat exchanger 1 and store it in the water storage tank 3 to realize the dust removal water Recycling.

The water level detection device can be set in the water storage tank 3, which can detect the water level in the water storage tank 3. When the water level in the water storage tank 3 is low, water can be added in time from the outside to ensure that there is enough water in the water storage tank 3 to meet Dust removal requirements. When the amount of water in the water storage tank 3 is too much, the excess water can be drained through the water receiving tray 2 or the water storage tank 3 to prevent the water flow in the water storage tank 3 from overflowing.

Preferably, the bottom of the water storage tank 3 can also be provided with a sewage outlet. The water stream after dust removal contains dust and other impurities, which will form precipitation in the water storage tank, resulting in the formation of dust deposits on the bottom of the water storage tank 3. The sludge at the bottom of the water storage tank 3 is discharged to ensure the cleanliness of the water body. Preferably, a filter may be provided on the pipeline connecting the water storage tank 3 to the water pump 4, which can filter the water flow from the water storage tank 3 into the water pump 4, and prevent the sludge from being transported into the water distribution tank 5 by the water pump 4 along with the water flow. Ensure the dust removal effect of the water flow, and improve the air cleaning efficiency and cleaning effect.

In this embodiment, the sprinkler device includes a water distribution box 5 and a plurality of nozzles 6 arranged at the bottom of the water distribution box 5. The water distribution box 5 is arranged on the top of the indoor heat exchanger 1, and the nozzles 6 are spaced along the length of the water distribution box 5. Set up. A plurality of nozzles 6 are arranged at even intervals along the length of the water distribution box 5, which can ensure the uniformity of the distribution of the nozzles 6, thereby enabling the nozzles 6 to evenly sprinkle water to the indoor heat exchanger 1, so that water flows in the indoor heat exchanger 1. It flows evenly on the upper surface to form a more even dust removal curtain, which improves the dust removal effect of the water flow.

Preferably, the surface of the heat exchange fins of the indoor heat exchanger 1 has a hydrophilic coating, and the hydrophilic properties of the heat exchange fins of the indoor heat exchanger 1 can be used to make water flow down the heat exchange fins to form a layer The water curtain can more effectively purify the air flowing through, and can ensure the continuity and continuity of the water curtain, and ensure the air purification effect.

Preferably, adjacent spray heads 6 at least partially overlap the water spray area on the top of the indoor heat exchanger 1. Since the spraying areas of adjacent nozzles 6 on the top of the indoor heat exchanger 1 overlap, it can be ensured that the spraying area of the nozzles 6 can cover the entire top area of the indoor heat exchanger 1, thereby forming a comprehensive surface on the indoor heat exchanger 1. The water curtain can avoid omissions, further ensure the cleaning effect of the air, and avoid dead spots in dust removal.

In this embodiment, a partition 7 is provided inside the water distribution box 5, and the partition 7 divides the water distribution box 5 into a water distribution chamber 9 located at the upper part and a water spray chamber 10 located at the lower part, and a water tank 8 is provided on the partition 7 , Along the direction of water flow, the width of the water tank 8 increases.

Since the kinetic energy of the water flow along the flow direction is gradually reduced, in order to ensure that the water flow can be evenly distributed in the water distribution tank 5, so that the spraying of the nozzle 6 can be more uniform, the partition 7 can be designed according to the characteristics of the water flow energy. The partition 7 realizes the redistribution of the water flow to ensure that the flow rate of the water flow at each position is basically the same, so that the amount of water in the spray chamber is basically the same along the length direction, and the uniformity of the spray water is ensured.

The water passage 8 can be a monolithic structure, and the width increases along the direction from one end to the other end of the partition 7, or a plurality of water passage grooves 8 can be arranged on the partition 7 at intervals from one end to the other end. The width of each water tank 8 increases sequentially.

In another embodiment, a water diversion net is also provided between the water spray device and the indoor heat exchanger 1. By setting the water distribution network, the water flow from the nozzle 6 can be redistributed on the water distribution network. The mesh of the water distribution network is more convenient to form the water flow into a water curtain, which can cover the entire indoor heat exchanger 1 more conveniently. Improve the dust removal efficiency of the air conditioner.

Preferably, the nozzle 11 of the spray head 6 is elongated, and the nozzle 11 is arranged along the width direction in the horizontal section of the indoor heat exchanger 1; or, the nozzle 11 is arranged along the length direction in the horizontal section of the indoor heat exchanger 1.

When the nozzle 11 is arranged along the width direction in the horizontal section of the indoor heat exchanger 1, a water curtain can be formed in the width direction of the indoor heat exchanger 1, so that the indoor heat exchanger 1 can have water flow in the entire width direction. The flow can ensure the uniformity of the water flow distribution, thereby ensuring the uniformity of the water curtain distribution on the indoor heat exchanger 1.

When the nozzle 11 is arranged along the length direction in the horizontal section of the indoor heat exchanger 1, a water curtain can be formed in the length direction of the indoor heat exchanger 1, so that there is water flow in the entire length direction of the indoor heat exchanger 1 After that, a complete water curtain can be formed to ensure that the air will inevitably flow through the water curtain. Purification by the water curtain improves the dust removal effect of the water curtain.

The nozzle 11 can be set to increase along the flow direction of the water flow, so that an expanded water flow can be formed at the spray end of the nozzle 11, and a larger area water curtain can be formed on the surface of the indoor heat exchanger 1, so that the entire indoor heat exchanger 1 Water flows through the surface, which can form a thicker water curtain. The air flowing through is filtered through multiple times to further improve the dust removal and purification effect.

Preferably, the spray head 6 is swingably arranged along the width direction in the horizontal section of the indoor heat exchanger 1. Since the nozzle 6 continuously swings along the width direction of the indoor heat exchanger 1, multiple water curtains can be continuously formed in the width direction of the indoor heat exchanger 1 to ensure the filtering effect of the air. This structure can be matched with the structure of the nozzle 11 arranged along the length direction. Through the swing of the nozzle 11 arranged along the length direction in the width direction, the spray length of the water flow and the spray width of the water flow are guaranteed, and the heat exchange in the room can be continued. Multiple water curtains are formed on the surface of the device 1 to improve the air purification effect of the water spray device.

In another embodiment, the spray head 6 is oscillatingly arranged along the longitudinal direction in the horizontal section of the indoor heat exchanger 1.

Preferably, the nozzle 6 includes at least two nozzles 11, of which one nozzle 11 is provided on one side of the width direction in the horizontal section of the indoor heat exchanger 1, and the other nozzle 11 is provided on the horizontal section of the indoor heat exchanger 1. The other side in the width direction. In this embodiment, each spray head 6 includes two nozzles 11, which can spray water on both sides of the indoor heat exchanger 1 in the width direction to form a double-layer water spray effect, thereby forming a double-layer water curtain. The structure is simple, and can form a stable and reliable purification water curtain to ensure the air purification effect.

In another embodiment not shown, a chute is provided at the bottom of the water distribution box 5, and the spray head 6 is slidably arranged along the length direction of the water distribution box 5. In this embodiment, the continuous sliding of the nozzle 6 can also avoid the dead angle of purification, ensure that the air flowing through each area of the indoor heat exchanger 1 can be effectively purified, and further improve the air purification effect.

The following table shows the index levels corresponding to the average daily concentration of PM2.5 in China and the United States. From the table, we can see the range of PM2.5 index in China and the United States and their corresponding air levels.

The air purification effect of the air conditioner of the present application is estimated below.

Take a vertical air conditioner with an air volume of 600m ³ /h as an example. The volume of the applied room is 5*4*3m. It is assumed that the purification efficiency of the air conditioner is not less than 25%, and the initial air index is 500, that is, the particle concentration is 500μg/ m ³ , calculate the indoor particulate matter concentration 1h after using the air conditioner of this application as

(1-25%) ^(600/5/4/3) *500＝0.57*500＝28.5μg/m ³

It can be seen from the formula that as long as the air purification efficiency of the air conditioner is not less than 25%, the indoor air quality can be reduced from an explosive meter to a good one within 1 hour, and the purification effect and purification efficiency are both high.

It should be understood that the present invention is not limited to the processes and structures that have been described above and shown in the drawings, and various modifications and changes can be made without departing from its scope. The scope of the present invention is only limited by the appended claims.
