Specifically, the groove bottom surface 1012 may be provided in various shapes such as a circle, an ellipse, a square, and the like.

In some embodiments, trough 1011 includes a trough floor 1012 and trough sides 1013, trough sides 1013 connecting water-receiving trough floor 101 to trough floor 1012, and trough sides 1013 being sloped, sloped trough sides 1013 directing water flow from water-receiving trough floor 101 into trough floor 1012; moreover, the inclined groove side 1013 can also play a role of buffering, so as to prevent large particle impurities from affecting the normal operation of the pump body 1031 of the drain pump 103.

Specifically, the recess side 1013 may be disposed on only one side of the drain pump 103, and certainly, in order to facilitate the accumulated water to smoothly flow into the recess 1011 from the bottom 101 of the water receiving tray, the recess side 1013 may be disposed on multiple sides of the drain pump 103, and the layout is performed according to the position relationship between the water receiving tray 100 and the recess 1011, which is not limited herein.

In some embodiments, the accumulated water may contain large particles that may interfere with the operation of the drain pump 103 after flowing into the groove 1011. To avoid this, the sump floor 1012 is provided with spacer ribs between the sump side 1013 and the drain pump 103. The vertical setting of isolation muscle is kept apart great impurity, filiform thing etc. and is avoided blockking up the flow path to maintain drain pump 103's effect, effectively solve the 100 ponding of water collector and the sanitary problem that causes.

As shown in fig. 5, when the water level switch 104 is disposed in the recess 1011, the design of the water-receiving tray 100 may be substantially the same as that of the above embodiment when the sterilizing box 102 is disposed in the recess 1011, and a detailed description thereof is omitted, and the structure of the water-receiving tray 100 when the water level switch 104 is disposed in the recess 1011 will be briefly described as follows:

in some embodiments, the float structure 1041 of the water level switch 104 is disposed in the groove 1011, and the float structure 1041 is only disposed in the groove 1011, so that the early warning operation of the water level switch 104 can be performed when the depth of the water accumulated in the groove 1011 satisfies the operating condition of the float structure 1041.

Further, the degree of depth of recess 1011 should be greater than the height of float structure 1041 apart from recess bottom surface 1012 to when ponding water level was lower in water collector 100, ponding flow in recess 1011, recess 1011 ponding height also can contact and float structure 1041, satisfies float structure 1041 operating condition, and water level switch 104 can carry out the early warning, reduces water level switch 104 and reports to the police the water level.

In addition, when the indoor unit 200 is installed obliquely and the water level of the water receiving tray 100 is high on one side and low on the other side, the water level switch 104 in the prior art cannot identify the water level abnormality, and the water level switch 104 in the embodiment of the present application can identify the water level abnormality to perform early warning, so as to prevent the occurrence of the overflow condition.

Specifically, the diameter of the groove 1011 should be larger than the diameter of the float structure 1041, so that the float structure 1041 can penetrate into the groove 1011.

In some embodiments, trough 1011 includes a trough floor 1012 and trough sides 1013, trough sides 1013 connecting water-receiving trough floor 101 to trough floor 1012, and trough sides 1013 being sloped, sloped trough sides 1013 directing water flow from water-receiving trough floor 101 into trough floor 1012; in addition, the inclined groove side 1013 can also play a role of buffering, so as to prevent large particles from affecting the normal operation of the float structure 1041 of the water level switch 104.

Specifically, the recess side 1013 may be disposed on only one side of the drainage pump 103, and of course, in order to facilitate the accumulated water to smoothly flow into the recess 1011 from the bottom 101 of the water receiving tank, the recess side 1013 may be disposed on multiple sides of the water level switch 104, and the layout is performed according to the position relationship between the water receiving tray 100 and the recess 1011, which is not limited herein.

In some embodiments, the accumulated water may contain large particles that may interfere with the operation of the level switch 104 after flowing into the recess 1011. To avoid this, the well floor 1012 is provided with a spacer rib between the well sides 1013 and the level switch 104. The vertical setting of isolation muscle is kept apart great impurity, filiform etc. and is avoided blockking up the flow path to maintain water level switch 104's effect, effectively solve the sanitary problem that water collector 100 ponding and cause.

The applicant has found that, in general, the water suction table of the drain pump 103 is arranged at the same position as the drain hole 105, and the drain hole 105 is arranged below the water suction table, so that the following problems are easy to occur:

1. the drain plug 106 of the drain hole channel 105 occupies a certain thickness, and in order to ensure the basic thickness of the drain plug 106, the depth of the water suction table is not enough, so that the water level surface of the drain pump 103 is higher, and water is easy to accumulate in the water pan 100; the problems that the water pan 100 is blocked by impurities caused by low-temperature condensation, mildew and corrosion of the water pan 100 and the output is low due to possible water soaking of the heat exchanger 204 are easily caused;

2. the drainage hole 105 is not well arranged, when the drainage hole 105 is close to the edge of the water pan 100, the drainage hole 105 and the drain plug 106 are easily shielded by the installed panel, and the problems that are easily caused are as follows: the drainage can be carried out only by detaching the panel when water drainage is needed, so that the maintenance is inconvenient; when a water leakage fault occurs at the position of the drain plug 106, the panel sponge compresses the drain plug 106, water is diffused to other areas and drips, problems are not easy to find, and maintenance and judgment are inconvenient;

3. the drain plug 106 in the drain hole channel 105 is limited by the structure, the effective sealing depth is insufficient, and water leakage fault is easily caused by aging and sealant failure.

In another embodiment of the present disclosure, as shown in fig. 7 to 9, the water-receiving tray 100 includes a water-receiving bottom surface 101, a groove 1011 and a drainage channel 105 are formed on the water-receiving bottom surface 101, the groove 1011 and the drainage channel 105 are disposed at an interval, the groove 1011 is used for placing a water suction port of the drainage pump 103, that is, the water suction port of the drainage pump 103 is disposed in the groove 1011, and the drainage channel 105 is provided with a drainage plug 106.

Separate the setting through with drainage channel 105 and recess 1011, under the same condition of water collector 100 thickness, because need not to set up drainage channel 105 in the recess 1011, and need not to consider drain plug 106 thickness, the degree of depth of recess 1011 is darker, the liquid level face of drawing water of drain pump 103 is changeed lowerly, more effectively take out the comdenstion water of water collector 100, avoid water collector 100 to ponding easily, then avoid causing water collector 100 low temperature condensation, go mildy, the corrosion causes impurity to block up water collector 100, and heat exchanger 204 probably bubble water leads to exporting low scheduling problem. Meanwhile, the groove 1011 and the drainage channel 105 are arranged separately, and the drainage channel 105 can be arranged at a position where the panel is not shielded, so that drainage, fault judgment and maintenance of the drainage plug 106 can be conveniently carried out without disassembling the panel. In addition, because the groove 1011 and the drainage channel 105 are arranged at intervals, the drainage channel 105 can deepen the sealing depth, so that a more optimized sealing scheme is convenient to be made on the structure, and the possibility of water leakage caused by failure of the position of the drainage plug 106 is reduced.

Further, as shown in fig. 9, a direction X is marked in fig. 9, and an arrow of the direction X indicates a direction below, i.e., a direction of a lower end, a bottom surface, and the like, and a direction opposite to the direction X indicates a direction above, i.e., a direction of an upper end, a top surface, and the like. The bottom of the groove 1011 has a thickness of 10mm to 18mm, for example 10mm, 12mm, 16mm or 18 mm. The bottom of the groove 1011 is proper in thickness, so that the phenomenon that the water receiving tray 100 is too thick as the bottom of the groove 1011 is too thick is avoided, and the thickness of the whole machine is prevented from being influenced; meanwhile, the situation that the bottom of the groove 1011 is too thin and influences the heat preservation effect to cause energy waste and influence the strength requirement of the groove 1011 is avoided. It should be noted that, in the thickness direction of the water collector 100, after the requirements of basic heat preservation and strength are met, the groove 1011 is as deep as possible, the position of the drain pump 103 can be set as low as possible, and the water level surface of the drain pump 103 for pumping water is effectively reduced.
