Specifically, the water receiving unit 1 in this embodiment is a chassis of the air conditioner, the chassis is integrally disposed in an inclined manner, and one end of the chassis, which is close to the water storage unit 2, is inclined downward, and certainly, the height of the horizontal plane where the water storage unit 2 is located cannot be higher than the description plane where the lowest part of the chassis is located, so that the condensed water can smoothly flow into the water storage unit 2 from the chassis; in addition, in the embodiment, the area of the bottom surface of the water storage unit 2 is limited to be smaller than that of the bottom surface of the water receiving unit 1.
Firstly, when the air conditioner is in a heating mode, namely the temperature of the external environment is low, the first heating unit 3 works and can heat condensed water on the water receiving unit 1 to prevent the condensed water from freezing, and therefore the influence on the performance of the air conditioner caused by interference collision between blades running at high speed outside the air conditioner and ice blocks is avoided; secondly, the water receiving unit 1 is connected with the water storage unit 2, and condensed water on the water receiving unit 1 flows onto the water storage unit 2 and then is heated by the second heating unit 4, so that the condensed water is vaporized, and zero emission is realized; moreover, the water receiving unit 1 is obliquely arranged, and one end of the water receiving unit, which is close to the water storage unit 2, is obliquely inclined downwards, so that condensed water can smoothly flow into the water storage unit; in addition, the water receiving unit 1 is actually the chassis of the air conditioner, and as is known, the area of the chassis is generally large, if the condensed water is evaporated at the chassis, the power is consumed very much, and the environment-friendly concept of energy conservation and emission reduction is not satisfied, so that the water receiving unit only preheats at the chassis and vaporizes at the water storage unit 2, and the energy consumption is reduced.
In the embodiment, in order to realize the inclined arrangement of the water receiving unit 1, there are a plurality of different specific structures, and two different specific structures are described below:
firstly, along a first direction, the included angle between the water receiving unit 1 and the horizontal plane is gradually increased; wherein the first direction is the direction of the water flow.
Secondly, the water receiving sheet 1 comprises at least two first areas 11, and included angles between the adjacent first areas 11 and a horizontal plane are sequentially increased along a first direction; wherein the first direction is the direction of the water flow.
For better illustration, as shown in fig. 3 and 4, it is assumed that the water receiving unit 1 includes three first areas 11, which are an area a, an area B, and an area C, respectively, along the direction of water flow, that is, the condensed water flows through the area a first, then the area B, and finally the area C; when the whole area A is located on the same plane, the included angle between the area A and the horizontal plane is assumed to be alpha, when the whole area B is located on the same plane, the included angle between the area B and the horizontal plane is assumed to be beta, and when the whole area C is located on the same plane, the included angle between the area C and the horizontal plane is assumed to be gamma, and alpha is more than beta and less than gamma.
On the basis of the definition of the included angle between the first area 11 and the horizontal plane, at least one of the areas A, B and C comprises at least two areas which are not on the same plane; i.e. within any one of the first regions 11, along the second direction, each first region 11 comprises at least one second region 12; wherein, the second direction and first direction are the direction on the coplanar, and the second direction is perpendicular to first direction, promptly: the first direction is perpendicular to the second direction in the horizontal direction.

Similarly, for better illustration, as shown in fig. 5 and fig. 6, the area a is in the same plane, that is, the area a includes one second area 12, the whole area B is not in the same plane, the area B includes three second areas 12, the whole area C is not in the same plane, and the area C includes three second areas 12.
Specifically, in the region B, as shown in fig. 5 and 6, three second regions 12, which are regions N, respectively 1 Region N 2 Region N 3 Then there is a region N 1 Angle to horizontal and area N 3 The included angle between the water tank and the horizontal plane is the same as that between the water tank and the horizontal plane and is C1; in the region C, three second regions 12, N respectively 1 、N 2 、N 3 Then there is a region N 1 Angle to horizontal and area N 3 The included angle with the horizontal plane is the same.
In addition, when the region B or the region C includes seven second regions 12, N respectively 1 、N 2 、N 3 、N 4 、N 5 、N 6 、N 7 Then, thenWith N 1 Angle to the horizontal plane and second region N 7 Angle to the horizontal plane is the same, N 2 Angle to the horizontal plane and second region N 6 Angle to the horizontal plane is the same, N 3 Angle to the horizontal plane and second region N 5 The included angle with the horizontal plane is the same.
In the embodiment, the included angles of different areas are limited, so that the condensed water can be gathered at the middle part as much as possible, and the gathered condensed water flows into the water storage unit 2 more easily.
In a specific embodiment: of the two adjacent first areas 11, the first area 11 close to the water storage unit 2 comprises X second areas 12, X respectively 1 、X 2 、X 3 ……X x The first region 11 remote from the water storage unit 2 comprises Y second regions 12, respectively Y 1 、Y 2 、Y 3 ……Y y When X and y are equal and are both odd numbers not less than 3, the second region X x+1/2 Angle with horizontal plane, second area Y y-1/2 Angle with horizontal plane, second area Y y+3/2 The included angles with the horizontal plane are the same.
Specifically, two adjacent first regions 11 are a region B and a region C, where the region B includes seven second regions, which are, in order, a region B1, a region B2, a region B3, a region B4, a region B5, a region B6, and a region B7; the region C comprises seven second regions, namely a region C1, a region C2, a region C3, a region C4, a region C5, a region C6 and a region C7 in sequence; then there are: the included angle between the area B4 and the horizontal plane, the included angle between the area C3 and the horizontal plane and the included angle between the area C5 and the horizontal plane are equal to each other.
More specifically, it is also possible to define that the angle of the area B3 to the horizontal plane, and the angle of the area C2 to the horizontal plane are both equal; the angle between the region B5 and the horizontal plane is equal to the angle between the region C6 and the horizontal plane. Further, the included angle between the area B2 and the horizontal plane and the included angle between the area C1 and the horizontal plane can be defined to be equal; the angle between the region B6 and the horizontal plane is equal to the angle between the region C7 and the horizontal plane.
The above-mentioned limited mode makes this implementation under the prerequisite that can smoothly drain water by whole chassis, must reduce the restraint to the different angles of chassis as far as possible, namely lets the different angles of chassis a little, can make chassis mould and subsequent manufacturing procedure simpler like this.
