After the indoor air or fresh air enters the purifying air duct 13 from the air inlet, impurities are filtered out through the water washing effect of the water washing device 2, and then the indoor air or fresh air is blown out from the air outlet to form circulation. For the sake of distinguishing from the air inlet and the air outlet of the indoor unit 100 of the air conditioner and facilitating the following better description, hereinafter, the description will be given by collectively defining the air inlet of the casing as the module air inlet 11 and the air outlet of the casing as the module air outlet 12. Generally, the housing is substantially cylindrical extending in the up-down direction, for example, the housing may be square or circular, etc. In addition, the shell can also be in a structure with two sealed ends. In an embodiment, the module air inlet 11 is disposed on the periphery of the housing, and the opening at the top end of the housing is disposed as the module air outlet 12, so as to realize air inlet at one end and air outlet at the other end. Of course, in other embodiments, the module outlet 12 may be disposed on the peripheral side of the housing. Preferably, a fan may be disposed on the housing to accelerate the circulation of air in the purifying air duct 13, so as to improve the purifying efficiency.

In this embodiment, the water inlet end of the first water pump 51 is connected to the water tank 3, the water inlet end of the second water pump 52 is connected to the water outlet end of the first water pump 51, the water outlet end of the second water pump 52 is connected to the water washing device 2, the water supply pipe 4 is not limited to a whole pipe, and the water supply pipe 4 may include a plurality of pipe sections and be respectively connected between the water tank 3, the first water pump 51, the second water pump 52 and the water washing device 2. When either the first water pump 51 or the second water pump 52 works alone, the power for pumping water from the water tank 3 to the water washing device 2 can be provided, but in order to avoid the excessive workload of the single water pump, the embodiment can also operate the first water pump 51 and the second water pump 52 to work simultaneously or alternatively, which not only helps to increase the pump lift and the flow rate, but also can keep working even if either the first water pump 51 or the second water pump 52 is damaged, and maintain the normal working of the whole air-conditioning indoor unit 100.

Further, in the present embodiment, the water tank 3 may be provided below the water washing device 2; the water supply pipe 4 extends vertically, and at this time, the first water pump 51 may be set to be communicated with the water inlet end of the water supply pipe 4, and the second water pump 52 may be set to be communicated with the middle section of the water supply pipe 4. The height difference is formed between the first water pump 51 and the second water pump 52, and in the embodiment, when the water washing device 2 of the indoor unit 100 of the air conditioner works, the first water pump 51 can be selected to work first, and after the water in the water tank 3 is pumped to the second water pump 52, the second water pump 52 is operated to work, so that the purpose of pumping the water to the water washing device 2 is finally achieved. In the process, because the first water pump 51 is arranged closer to the water tank 3, the possibility of air entering the first water pump 51 is lower, the enough vacuum degree in the first water pump 51 can be ensured, and even if the first water pump 51 is started after being stopped, the dry pumping phenomenon can not occur; then, because the first water pump 51 firstly works to pump water to the second water pump 52, air entering the second water pump 52 can be evacuated, and the vacuum degree inside the second water pump 52 is improved, so that the second water pump 52 can be ensured to quickly feed water, the dry pumping risk of the second water pump 52 is reduced, and the reliability of the whole air-conditioning indoor unit 100 is improved.

In this embodiment, the second water pump 52 is mounted in the mounting area, and may be fixedly mounted to the back panel 14, the mounting bracket 16, or other structure in the mounting area. Since the installation area is far away from the air outlet end of the indoor unit 100, that is, away from the user, the second water pump 52 is installed in the installation area, which is helpful to reduce the influence of the working noise generated by the second water pump 52 on the user, and improve the comfort level of the indoor unit 100.

It should be noted that, in the present design, the specific installation manner of each of the first water pump 51 and the second water pump 52 in the cabinet 1 is not limited, and the indoor air conditioning unit 100 further includes an installation structure 6, where the installation structure 6 can realize the fixed installation of the first water pump 51 and/or the second water pump 52, taking the installation of the first water pump 51 as an example, as shown in fig. 5, the installation structure 6 includes a pressing portion 61, and the pressing portion 61 is, for example, a pressing plate or a pressing block. The pressing part 61 is arranged in the water tank 3 and is positioned on one side of the first water pump 51 back to the inner wall of the water tank 3, and the pressing part 61 can press the first water pump 51 towards the direction of the inner wall of the water tank 3 in a screw connection fixing or bonding fixing mode and the like so as to achieve the purpose of clamping the first water pump 51 together with the inner wall of the water tank 3.

Further, in the present embodiment, the pressing portion 61 has the abutment surface 611, the abutment surface 611 abuts against the outer wall surface of the first water pump 51, and the shape of the abutment surface 611 matches the shape of the outer wall surface of the first water pump 51. For example, when the outer wall surface of the first water pump 51 is provided in a convex arc surface shape, the abutting surface 611 is provided in a concave arc surface shape corresponding to the convex arc surface, which facilitates close contact between the pressing portion 61, the first water pump 51, and the inner wall of the water tank 3. Further, a protective pad made of, for example, a rubber material may be disposed between the abutting surface 611 and the corresponding outer wall surface of the first water pump 51, and the protective pad is used to convert the rigid connection between the pressing portion 61 and the first water pump 51 into a flexible connection, so that the abrasion of the pressing action of the pressing portion 61 on the outer wall of the first water pump 51 can be eliminated, and the damping effect can be achieved.

The second water pump 52 may be installed in the same manner as described above, and will not be described herein. Of course, a boss may also be directly disposed on the outer wall of the second water pump 52, the boss is provided with a threaded hole, and then the second water pump 52 is mounted in the casing 1 by a screw, wherein the boss, the threaded hole and the screw constitute the mounting structure 6.

In order to facilitate the user to add water to the water tank 3 in time, in an embodiment, the water tank 3 may be fixedly installed in the casing 1, and a water inlet communicated to the inside of the water tank 3 is formed on the casing 1 corresponding to the water tank 3, through which the user can add water to the water tank 3; or, as in this embodiment, an opening 17 may be formed in the casing 1, and then a sliding groove is formed in one of the bottom of the casing 1 and the bottom of the water tank 3, wherein the other sliding rail is convexly provided, and the sliding rail is matched with the sliding groove, so that the water tank 3 can be accommodated in the casing 1, and can also be slidingly extracted to the outside of the casing 1 through the opening 17, which is convenient for a user to extract the water tank 3 to perform a water adding operation or perform replacement and maintenance.

The first pipe section 41 can move synchronously with the movement of the water tank 3, for example, when the water tank 3 is drawn out due to external force, the first pipe section 41 is separated from the second pipe section 42, so that the water supply pipe 4 is disconnected, and at this time, the first water pump 51 and the second water pump 52 can be set to be automatically closed when the disconnection of the water supply pipe 4 is sensed by related sensors, so as to avoid idle running or dry pumping; when the water tank 3 is again accommodated in the cabinet 1, the first pipe section 41 is reconnected to the second pipe section 42, ensuring that the arrangement of the water supply pipe 4 does not interfere with the movement of the water tank 3. In addition, when the water tank 3 and the inner wall of the housing 1 are slidably engaged with the sliding rail through the sliding groove as described above, the extending direction of the sliding groove determines the fixed moving track of the water tank 3, so that the water tank 3 can drive the first pipe section 41 to move along the fixed track to be connected with the second pipe section 42, which helps to prevent the water tank 3 from shifting in the moving process, and the problem that the first pipe section 41 and the second pipe section 42 cannot be aligned is caused.

Of course, there are various technical solutions for detachably connecting the first pipe section 41 and the second pipe section 42, for example, the first pipe section 41 and the second pipe section 42 may be magnetically attracted and fixed or snap-fit connected, and in this embodiment, the first pipe section 41 is sleeved on the second pipe section 42. That is, the respective joints of the first pipe section 41 and the second pipe section 42 are different in size, and the outer diameter of one of the first pipe section 41 and the second pipe section 42 is matched with the inner diameter of the other one of the first pipe section and the second pipe section, so that the clamping and the limiting of the two are facilitated.

In order to improve the tightness of the connection between the first pipe section 41 and the second pipe section 42, in this embodiment, the air conditioning indoor unit 100 further includes a sealing ring 7, and the sealing ring 7 is sealingly installed at the sleeve joint between the first pipe section 41 and the second pipe section 42. Specifically, when the second pipe section 42 is sleeved in the first pipe section 41, the sleeved part of the second pipe section 42 may be annularly provided with an annular groove for the sealing ring 7 to be embedded, wherein the groove depth of the annular groove is preferably smaller than the difference between the inner diameter and the outer diameter of the sealing ring 7, so that when the sealing ring 7 is embedded in the annular groove, the annular groove slightly protrudes out of the peripheral wall of the second pipe section 42, and thus when the second pipe section 42 is sleeved in the first pipe section 41, the sealing ring 7 and the inner wall of the first pipe section 41 are squeezed to generate an elastic abutting force, thereby achieving a better sealing effect.

Further, in the present embodiment, the plurality of seal rings 7 are provided at intervals in the water supply direction. The plurality of sealing rings 7 can provide multiple sealing effects; furthermore, in the event of partial failure of the plurality of sealing rings 7, the remaining sealing rings 7 still ensure a sealed connection of the first pipe section 41 to the second pipe section 42.
