In the drainage board 100 of the present embodiment, an angle is formed between the extending direction of the water guide 120 and the first air outlet direction, that is, an angle is formed between the extending direction of the water guide 120 and the front-back direction. The first air inlet 2121 may be disposed on at least one of the left and right sides of the first air duct assembly 200, a communication path between the first air inlet 2121 and the air outlet forms a second air outlet direction, and an extending direction of the water guide portion 120 forms an included angle with the second air outlet direction. The extending direction of the water guide portion 120 forms an included angle with the first air outlet direction, and the extending direction of the water guide portion 120 forms an included angle with the second air outlet direction, which can be understood as the first included angle θ₁。

The extending direction of the water guide 120 may be a straight path or a curved path.When the extension path of the water guide 120 is a straight path, a path from one end of the water guide 120 away from the drain 110 to the other end of the water guide 120 communicating with the drain 110 is an extension path. When the extending path of the water guide 120 is a curved path, the water guide 120 of the curved path may have a plurality of ends communicating with the drain 110, the curved path may be a polygonal line path formed by a plurality of straight line paths, or the curved path may be a curve having one or more curvature radii, and the shape of the curved path may be set as desired.

It can be understood that, toward the drain part 110, the bottom of the water guide part 120 is inclined in a first direction forming a second angle θ with the top surface of the drain plate 100₂. That is, the bottom of the water guide part 120 is inclined, and the water in the water guide part 120 is collected to the water discharge part 110 along an inclined path (first direction), so that the water discharge effect is better, the problem of local water accumulation can be avoided, and the water can flow stably.

When the top surface of the drainage plate 100 is horizontally disposed, it can be understood that the first direction forms a second included angle θ with the horizontal plane₂. The water guide 120 is formed along the top surface of the drain plate 100 to be gradually depressed downward from one end distant from the drain 110 to a position communicating with the drain 110. At this time, the second angle θ₂The first direction is an inclined downward direction, which is an included angle between the bottom of the water guide part 120 and the horizontal plane.

The bottom of the water guide part 120 may be an inclined line or an inclined plane, and in some cases, the bottom of the water guide part 120 is an inclined plane, and the inclined plane may be a plane or a curved surface, which may be specifically selected as required.

In some cases, the bottom of the water guide 120 does not form a continuous oblique line or slope, such as a step shape, and still meets the water guide requirement.

It can be understood that the second included angle theta₂Less than or equal to 7 DEG, second included angle theta₂The angle of little, help reducing the distance of drain bar 100 top surface to bottom surface, can realize the drainage of small-angle, and then reduce first wind channel subassembly 200 at the size of direction of height, reduce the shared space of first wind channel subassembly 200, help promoting refrigeration plant's storing space, provide the refrigeration plant of a large capacity.

In some cases, second included angle θ₂Set up to 3, 3 can satisfy drain bar 100's drainage demand, can also fully reduce drain bar 100's height, realize the small-angle drainage.

It can be understood that, a plurality of water guiding portions 120 are arranged side by side on the same side of the drainage portion 110, and the corresponding bottom surfaces of the drainage plates 100 are coplanar, so that the bottom surfaces of the drainage plates 100 are better in flatness, the appearance of the drainage plates 100 is concise, and positioning and installation are convenient.

Here, the parallel arrangement is understood to mean that the plurality of water conveying parts 120 are arranged in order on one side in the extending direction of the drain part 110. In general, a plurality of water guide portions 120 are provided in parallel on both sides of the drain portion 110, that is, the drain portion 110 is provided between two rows of the water guide portions 120. Of course, when the drain part 110 is provided at the end of the drain plate 100, the water guide part 120 is provided only at one side of the drain part 110.

It can be understood that the extending direction of the water guide part 120 is perpendicular to the air outlet direction, so that the wind can be effectively prevented from being discharged from the space defined by the water guide part 120, and the staying time of the wind in the first cavity 260 can be effectively prolonged, so as to fully exchange heat.

It will be appreciated that the depth of depression of the drain 110 increases progressively towards the outlet 114, so that water within the drain 110 flows under gravity towards the outlet 114.

It can be understood that the bottom of the drain part 110 is inclined in the second direction forming a third angle theta with the top surface of the drain plate 100₃. That is, the bottom of the drainage part 110 is inclined, and the water in the drainage part 110 is collected to the outlet 114 along an inclined path (second direction) and is discharged, so that the drainage effect is good, and the problem of local water accumulation can be avoided; and water can flow smoothly.

When the top surface of the drainage plate 100 is horizontally disposed, it can be understood that the second direction forms a third included angle θ with the horizontal plane₃. The drain portion 110 is formed along the top surface of the drain plate 100 to be gradually depressed downward toward the outlet 114. At this time, the third included angle θ₃The second direction is an inclined downward direction, which is an included angle between the bottom of the drainage portion 110 and the horizontal plane.

The bottom of the drainage part 110 may be an inclined plane or an inclined plane, and in some cases, the bottom of the drainage part 110 is an inclined plane, and the inclined plane may be a plane or a curved surface, which may be specifically selected as required.

In some cases, the bottom of the drainage portion 110 does not form a continuous slope or slant, such as a step shape, and still meets the drainage requirement.

It can be understood that the third included angle theta₃Can be less than or equal to 7 DEG, and the third included angle theta₃The angle of (2) is small, which is helpful to reduce the distance from the top surface to the bottom surface of the drainage plate 100, and can realize small-angle drainage, thereby reducing the size of the first air duct assembly 200 in the height direction and reducing the second air duct assemblyThe space occupied by the air duct assembly 200 is beneficial to improving the storage space of the refrigeration equipment, and the refrigeration equipment with large capacity is provided.

It should be noted that the third included angle θ₃Also can be greater than 7, because the area of the shared drain bar 100 of drain part 110 is less, the angle that drain part 110 downward sloping is slightly bigger, and is little to the whole volume influence of drain bar 100, consequently, to third contained angle theta₃The angle of (c) is not strictly limited.

It can be understood that the extending direction of the water discharging part 110 and the air outlet direction form a fourth included angle, so that the air is discharged along the extending direction of the water discharging part 110 as much as possible, the staying time of the air in the first cavity 260 can be prolonged, and the heat exchange effect is ensured.

Of course, the drainage portion 110 may also extend along the air outlet direction, and the water guide portions 120 may be symmetrically disposed on both sides of the drainage portion 110, so that the water guide portions 120 on both sides of the drainage portion 110 may guide water uniformly and stably.

It is understood that, as shown in fig. 16 and 17, the depth of the depression of the water discharge part 110 is greater than or equal to the depth of the depression of the water guide part 120. That is, the minimum depth of the water discharging part 110 needs to be greater than or equal to the maximum depth of the water guiding part 120 so that the water of the water guiding part 120 can be collected to the water discharging part 110 to prevent the water from being accumulated in the water guiding part 120.

As shown in fig. 14, 15 and 18, a plurality of water guide portions 120 are provided in parallel on both sides of the drain portion 110, and the plurality of water guide portions 120 guide water in different portions into the drain portion 110. By providing a plurality of water guides 120, it can also be understood that both sides of the drain 110 form a wave-shaped structure, so as to reduce the area of the top surface of the drain 100 as much as possible, and reduce the accumulated water on the top surface of the drain 100, so that the water received by the drain 100 is discharged from the outlet 114 along the water guides 120 and the drain 110 as soon as possible.

If the number of the water discharge portions 110 is increased without changing the area of the water discharge plate, the length of the water guide portion 120 can be shortened, and water can be rapidly introduced into the water discharge portion 110.

The adjacent water discharging parts 110 are a first water discharging part 111 and a second water discharging part 112, a first water guiding area 130 located on one side of the first water discharging part 111 and a second water guiding area 140 located on one side of the second water discharging part 112 are configured between the first water discharging part 111 and the second water discharging part 112, the depth of the water guiding part 120 of the first water guiding area 130 is gradually increased towards the direction of the first water discharging part 111, and the depth of the water guiding part 120 of the second water guiding area 140 is gradually increased towards the direction of the second water discharging part 112. That is, at the position where the first water guiding region 130 and the second water guiding region 140 are butted against each other, the depth of the depression of the water guiding part 120 is minimized, which facilitates the water received by the first water guiding region 130 to be guided to the first water discharging part 111, and the water received by the second water guiding region 140 to be guided to the second water discharging part 112, thereby shortening the length of the water guiding part 120 and facilitating the water to be collected to the water discharging part 110.

The drainage part 110 extends from front to back, and the drainage part 110 forms a third included angle theta with the horizontal plane from front to back₃Third angle of inclination theta₃The height variation in the front-rear direction of the drain board 100 is affected, but the drain part 110 is provided in the area of the drain board 100 as a wholeThe area of the water draining plate 100 occupied by the water draining part 110 is small, the local position inclination angle of the water draining plate 100 is slightly large, the influence on the whole indoor storage space of a room is small, and the indoor volume of the room can be optimized.
