When the opening 170 of the drain panel 100 functions to divert a portion of the intake air, the depth of the water guide recessed with respect to the top surface of the drain panel 100 may not be limited.
In some cases, the water guide recess gradually increases in depth toward the opening 170, and the water guide of such a structure may be referred to as a second water guide 130. That is, the second water guide 130 has a greater depth toward the end of the opening 170, which helps guide the flow of air therein. When the evaporator 230 is placed above the drain board 100, the depth of the second water guiding part 130 is gradually increased, and the distance between the evaporator 230 and the drain board 100 can also be increased, so that the flowing space of wind is properly enlarged; it also helps the defrost water received by the drain plate 100 to be drained from the opening 170.
The depth of the second water guide 130 gradually increases toward one end of the opening 170, and may be continuously increased or increased in a step shape.
It can be understood that, toward the opening 170, the bottom of the second water guide part 130 is inclined in a first predetermined direction, and the first predetermined direction forms a first predetermined angle with the top surface of the drain plate 100. That is, the bottom surface of the second water guide part 130 is an inclined surface extending downward along the first predetermined direction, which facilitates the wind flowing into the first cavity 282 and also facilitates the drainage.
The first predetermined direction is a direction forming a first predetermined included angle with the top surface and inclined downward toward the opening 170 along the predetermined surface, and the size of the first predetermined included angle can be selected as required.
In order to reduce the size of the drain bar 100 in the height direction, a first preset included angle can be an included angle smaller than or equal to 7 degrees, the drainage effect and the air guide effect can meet the requirements, the size of the air duct assembly 200 in the height direction can also be reduced, the height direction space in the cabinet body 400 occupied by the air duct assembly 200 is reduced, the compartment space in the cabinet body 400 is increased, and therefore the refrigeration equipment with large capacity is provided.
Under some circumstances, first preset contained angle sets up to 3, and 3 can satisfy drain bar 100's drainage demand, can also fully reduce drain bar 100's height, realize the low-angle drainage. Of course, the first preset included angle may also be set to 1 °, 2 °, 4 °, 5 °, 6 °, or 7 °.
Of course, the depth of the second water guide part recess may be constant (not shown), and the second water guide part recess may have a uniform depth, and may also perform the functions of guiding and draining water.
It is understood that the water guide includes a guide surface disposed along an extending direction of the water guide, the guide surface being adjacent to an opposite side surface thereof in a direction from the top surface to the bottom surface of the drain board 100. That is, the second water guide 130 is provided with a third guide surface 131 along the extending direction thereof, the third guide surface 131 is close to the opposite side surface from the top surface to the bottom surface of the drain board 100, and the third guide surface 131 is an inclined surface inclined to the opposite side thereof.
The defrosting water received by the top surface of the drainage plate 100 and the third flow guiding surface 131 may fall into the bottom of the water guide part along the flow guiding direction of the third flow guiding surface 131, so that the defrosting water is collected in the water guide part, and the water in the water guide part is drained.
The opposite side of the third guiding surface 131 may be a vertically disposed surface, or may also be a guiding surface, which may be specifically selected as required. As shown in fig. 5 and 6, both opposite side surfaces of the second water guide part 130 are third guide surfaces 131.
As shown in fig. 5 to 7, a plurality of second water guiding parts 130 are disposed on each side of the predetermined surface of the drain board 100, the plurality of second water guiding parts 130 are disposed in parallel, and a plurality of openings 170 are formed on both sides of the drain board 100, so that part of the intake air from the first intake vent 201 can enter the first cavity 282 along the plurality of openings 170.
At the preset height position, the width of the second water guide 130 gradually decreases toward the opening 170, so that the water received in the second water guide 130 can be collected toward the opening 170.
As shown in fig. 1 to 7 and described above, the drain board 100 having the second water conveying part 130 may not include the drain part 110.
Referring to fig. 1 to 16 and 20 to 25, in an embodiment of the present invention, another drainage plate 100 is provided, in which the drainage plate 100 is configured with a water guiding portion recessed relative to a top surface of the drainage plate 100, and an extending direction of the water guiding portion forms a fourth angle with an air outlet direction above the drainage plate 100.
When the drain plate 100 and the evaporator 230 are both disposed in the first cavity 282 of the air duct assembly 200, the wind enters the first cavity 282 from the wind inlet of the air duct assembly 200 and flows toward the wind outlet, and the wind in the first cavity 282 flows in the space between the drain plate 100 and the evaporator 230 and the space inside the evaporator 230. When wind flows between the drainage plate 100 and the evaporator 230, the water guide portion and the wind outlet direction form a fourth included angle θ 1, so that the wind can be inhibited from directly flowing to the wind outlet from the water guide portion, the staying time of the wind in the first cavity 282 is prolonged, the wind is fully contacted with the evaporator 230 and exchanges heat, the wind after heat exchange is discharged from the wind outlet, and the heat exchange efficiency is improved.
The air outlet direction is the direction from the air inlet to the air outlet, and in some cases, only one air inlet and one air outlet are arranged in a one-to-one corresponding relationship to form an air outlet direction; in some cases, at least one of the air inlet and the air outlet is provided with a plurality of air outlets, and a plurality of air outlet directions can be formed. The extending direction of the water guide part forms an included angle with at least one air outlet direction, and the included angle can be in one direction, so that the heat exchange efficiency of air is ensured; of course, the extending direction of the water guide part and all the air outlet directions form included angles, so that effective heat exchange of the air in a plurality of flow paths can be guaranteed, and the heat exchange efficiency can be guaranteed. The air inlet is generally disposed at one end of the air duct assembly 200 near the front, the air outlet is generally disposed at one end of the air duct assembly 200 near the rear, and the air outlet direction can be from front to rear.
When the air inlets are divided into a first air inlet 201 and a second air inlet 202, the second air inlet 202 is disposed in front of the air duct assembly 200, the air outlet is disposed behind the air duct assembly 200, a communication path between the second air inlet 202 and the air outlet forms a first air outlet direction, and the second air inlet 202 corresponds to a position below the evaporator 230, the air flows along a direction from bottom to top and from front to back.
In the drainage board 100 of this embodiment, an included angle is formed between the extending direction of the water guide portion and the first air outlet direction, that is, an included angle is formed between the extending direction of the water guide portion and the front-back direction. The first air inlet 201 may be disposed on at least one of the left and right sides of the air duct assembly 200, a communication path between the first air inlet 201 and the air outlet forms a second air outlet direction, and an extending direction of the water guide portion forms an included angle with the second air outlet direction. The extension direction of the water guide part and the first air-out direction form an included angle, and the extension direction of the water guide part and the second air-out direction also form an included angle, which can be understood as a fourth included angle, but the specific angle values can be the same or different.
The extending direction of the water guide portion may be a straight path or a curved path. When the extension path of the water guide part is a straight path, a path from one end of the water guide part far from the drain part 110 to the other end of the water guide part communicating with the drain part 110 is an extension path; when the extended path of the water guide portion is a curved path, the water guide portion of the curved path may have a plurality of ends communicating with the drain portion 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. The extending direction of one water guide part can form one or more included angles with the air outlet direction, namely the fourth included angle can be one or more angle values, and the fourth included angle can be specifically set as required. Referring to fig. 10 to 25, in an embodiment of the present invention, there is provided another drain panel 100, the drain panel 100 being configured with a drain part 110 and a water guide part, the drain part 110 being configured with an outlet 114, the drain part 110 being recessed with respect to a top surface of the drain panel 100; the water guide part is communicated with the water drainage part 110, the water guide part is recessed relative to the top surface of the water drainage plate 100, and a fifth included angle theta 1 is formed between the extending direction of the water guide part and the air outlet direction above the water drainage plate 100.
In the use state, the drain plate 100 is disposed below the evaporator 230 and receives defrosted water generated when frost on the surface of the evaporator 230 is heated. Some of the water falls into the water guide portion and is guided into the drain portion 110 along the extending direction of the water guide portion, and a plurality of water guide portions are generally provided, and the water received by each water guide portion is collected into the drain portion 110 and is discharged through the outlet 114 of the drain portion 110. The other part of the water directly falls into the drain part 110 and is discharged through the drain part 110.
The water guide part is arranged in the water discharging plate, and the water guide part is arranged in the water discharging plate; and in the water discharging plate only provided with the water guide part, the extending direction of the water guide part and the air outlet direction form an included angle which is a fourth included angle. The angle values of the fifth angle and the fourth angle can be selected according to needs, and are not limited herein.
In fig. 23, a solid arrow above the drain board 100 indicates an extending direction of the water guide portion, a dotted arrow indicates an air outlet direction, and indicates a fifth included angle θ 1, which indicates a case where the fifth included angle is 90 °.
It should be noted that the water guiding part and the water discharging part 110 are both recessed based on the top surface of the water discharging plate 100, the top surface may be a plane or a curved surface, and the top surface may be a surface defined by a plurality of lines or a surface defined by a plurality of surfaces. Correspondingly, the bottom of the water guide part and the bottom of the drain part 110 form the bottom surface of the drain board 100, the bottom surface may also be a plane or a curved surface, and the bottom surface may be a surface defined by a plurality of lines or a surface defined by a plurality of surfaces. The upper surface of the drain board 100 is the entire surface of the drain board 100 facing upward, and the top surface is a part of the upper surface; the lower surface of the drain board 100 is the entire surface of the drain board 100 facing downward, and the bottom surface is a part of the lower surface.
In the water discharge plate 100 of the embodiment, the water guide part is matched with the water discharge part 110, so that the received water can be discharged, the problem of water discharge in the air duct assembly 200 is solved, and the water guide part is arranged in the extending direction to form an included angle with the air outlet direction of the air duct assembly 200, so that the staying time of air in the air duct assembly 200 can be prolonged, namely the heat exchange time is prolonged, the heat exchange efficiency is improved, and the refrigeration requirement of refrigeration equipment is met; the drain board 100 is simple in structure.
In the drain board 100 according to the embodiment of the utility model, when the depth of the water guide portion recessed downward with respect to the top surface of the drain board 100 is not changed, and the drain board 100 is configured with the drain portion 110 recessed with respect to the top surface of the drain board 100, this water guide portion may be referred to as a third water guide portion 140, as shown in fig. 11 to 13, the drain portion 110 is configured with the outlet 114, the third water guide portion 140 is communicated with the drain portion 110, the defrosting water received by the third water guide portion 140 can be discharged from the opening 170 at the end of the drain board 100, and can also be discharged from the outlet 114 of the drain portion 110, so that multi-directional drainage is realized, the structure is simple, and the drainage effect is good.
At this time, the evaporator 230 and the drain plate 100 may be horizontally disposed, thereby accomplishing the discharge of the defrost water and reducing the height of the air duct assembly 200. If the evaporator 230 and the drain plate 100 are both disposed obliquely downward for draining water, the downward inclination angle of the evaporator 230 and the drain plate 100 (the downward inclination angle of the evaporator 230 and the drain plate 100 may be less than or equal to 7 °) may be reduced, and the size of the air duct assembly 200 in the height direction may be reduced, thereby expanding the capacity of the refrigeration equipment.
The outlet 114 of the drainage portion 110 and the air outlet are located at the same side of the first cavity 282, and the drainage portion and the air outlet are located at the same side of the first cavity 282, so that the drainage structure and the air outlet structure are integrated conveniently.
When the fan 270 is disposed in the air duct assembly 200, the fan 270 and the air outlet are located on the same side, that is, the outlet 114, the air outlet and the fan 270 are located on the same side, and the defrosting water of the fan 270 can be discharged along with the defrosting water of the drain plate 100.
The plurality of third water guides 140 are disposed in parallel on both sides of the drain part 110 along the extending direction of the drain part 110, and the plurality of third water guides 140 are distributed under the evaporator 230 so as to receive the defrost water at a plurality of positions under the evaporator 230, which facilitates rapid drainage.
The number of the water discharging parts 110 may be plural, and the plural water discharging parts 110 may be parallel or form an included angle. In the case where the area of the drain plate 100 is not changed, the greater the number of the drain parts 110, the shorter the length of the third water conveying part 140, which contributes to the collection of the water received by the third water conveying part 140 in the drain part 110, so as to shorten the defrosting and draining time. When a plurality of water discharge parts 110 are provided, the third water guide part 140 near the edge of the water discharge plate has an opening, and the other third water guide parts 140 communicate with the water discharge part 110.
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 seventh angle θ 3 with the top surface of the drain plate 100. 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 drain board 100 is horizontally disposed, it can be understood that the second direction forms a seventh angle θ 3 with the horizontal plane. Along the top surface of the drain plate 100, a drain portion 110 is formed to be gradually depressed downward toward the position of the outlet 114. At this time, the seventh angle θ 3 is an angle between the bottom of the drainage portion 110 and the horizontal plane, and the second direction is a downward oblique direction.
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 seventh included angle θ 3 may be less than or equal to 7 °, and the angle of the seventh included angle θ 3 is small, which is helpful to reduce the distance from the top surface to the bottom surface of the drainage plate 100, so as to realize drainage at a small angle, further reduce the size of the air duct assembly 200 in the height direction, reduce the space occupied by the air duct assembly 200, be helpful to promote the storage space of the refrigeration equipment, and provide the refrigeration equipment with a large capacity.
It should be noted that the seventh included angle θ 3 may also be greater than 7 °, because the area of the drainage plate 100 occupied by the drainage portion 110 is small, the angle at which the drainage portion 110 is inclined downward is slightly large, and the influence on the overall volume of the drainage plate 100 is not large, the angle of the seventh included angle θ 3 is not strictly limited.
In some cases, as shown in fig. 12, the depth of the recess of the drainage part 110 is constant, and in this case, the drainage part may be referred to as a third drainage part 115, and the drainage plate 100 is inclined toward the outlet 114 to facilitate drainage. If the outlet 114 is located at the rear end of the duct assembly 200, the drain plate 100 is inclined obliquely downward from front to rear so that the water in the drain portion 110 flows rearward and is discharged.
As shown in fig. 11 and 12, the third water guide part 140 includes a fourth guide surface 141 provided along an extending direction of the third water guide part 140, and the fourth guide surface 141 approaches to an opposite side surface thereof in a direction from the top surface to the bottom surface of the drain board 100. The fourth guide surface 141 guides the defrosted water received by the top surface of the drain plate 100 and the fourth guide surface 141 to the bottom of the third water guide 140 so that the water in the third water guide 140 is discharged.
The fourth guide surface 141 is inclined toward the outlet 114 from the bottom surface toward the top surface of the drain plate 100. When the water discharge plate 100 is inclined toward the outlet 114 and the amount of water collected in the third water guide part 140 is large, the fourth guide surface 141 guides the water rearward to guide a part of the water to be discharged rearward.
In the embodiment of the present invention, as shown in fig. 20 to 25, the water guide portion may be referred to as a first water guide portion 120 when the water guide portion is recessed to a depth gradually increasing toward the water discharge portion 110. The first water guide 120 gradually increases in depth toward the drain 110 such that water flows toward the drain 110 by gravity and is discharged from the outlet 114 of the drain 110.
It can be understood that, toward the direction of the drain part 110, the bottom of the first water guiding part 120 is inclined in the first direction, and the first direction forms a sixth angle θ 2 with the top surface of the drain plate 100. That is, the bottom of the first water guide part 120 is inclined, and the water in the first 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 good, and the problem of local water accumulation can be avoided; and water can flow smoothly.
When the top surface of the drain board 100 is horizontally disposed, it can be understood that the first direction forms a sixth angle θ 2 with the horizontal plane. The first water guide 120 is formed to be gradually depressed downward from one end distant from the drain part 110 to a position communicating with the drain part 110 along the top surface of the drain plate 100. At this time, the sixth angle θ 2 is an angle between the bottom of the first water guide 120 and the horizontal plane, and the first direction is a downward direction.
The bottom of the first water guiding part 120 may be an inclined line or an inclined plane, and in some cases, the bottom of the first water guiding 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 first water guiding part 120 does not form a continuous oblique line or an inclined plane, such as a step shape, and still can satisfy the water guiding requirement.
It can be understood that sixth included angle θ 2 is less than or equal to 7 °, and the angle of sixth included angle θ 2 is little, helps reducing the distance from the top surface to the bottom surface of drain plate 100, can realize the drainage of small angle, and then reduces air duct assembly 200 in the size of direction of height, reduces the space occupied by air duct assembly 200, helps promoting refrigeration plant's storing space, provides a refrigeration plant of large capacity.
Under some circumstances, sixth contained angle θ 2 sets up to 3, and 3 can satisfy drain bar 100's drainage demand, can also fully reduce drain bar 100's height, realize the small-angle drainage. Of course, the sixth angle may also be 1 °, 2 °, 4 °, 5 °, or 6 °.
In some cases, the first water conveying part 120 is different from the third water conveying part 140 described above in that the first water conveying part 120 is inclined toward the drain part 110 in the drain board 100, the third water conveying part 140 is inclined toward the end of the drain board 100, that is, the inclination direction is different, and other structures and parameters may be set to be the same, for example, the inclination angle may be the same.
It can be understood that, a plurality of water guiding portions are arranged in parallel 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 smoothness, the appearance of the drainage plates 100 is simple, and the positioning and the installation are convenient.
Here, the parallel arrangement is understood to mean that a plurality of water guide portions are arranged in order on one side in the extending direction of the drain portion 110. In general, a plurality of water guide portions are provided in parallel on both sides of the drain portion 110, that is, the drain portion 110 is provided between two rows of water guide portions. Of course, when the drain part 110 is provided at the end of the drain plate 100, the water guide part is provided only at one side of the drain part 110.
It can be understood that the extending direction of the water guide part is perpendicular to the air outlet direction, so as to effectively prolong the stay time of the air in the first cavity 282, and fully exchange heat.
It can be understood that the extending direction of the water discharging part 110 and the air outlet direction form an eighth included angle, so that the extending direction of the air discharging part 110 is reduced as much as possible, the staying time of the air in the first cavity 282 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 may be symmetrically disposed on both sides of the drainage portion 110, so as to facilitate uniform and stable water guide of the water guide portions on both sides of the drainage portion 110.
As shown in fig. 20 and 25, when the water discharge portion 110 extends in the air outlet direction, the water guide portion is perpendicular to the air outlet direction, and the air entering the water guide portion is minimized.
It is understood that, as shown in fig. 24 and 25, 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. 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 so that the water of the water guiding part can be gathered to the water discharging part 110 to prevent the water from being accumulated in the water guiding part.
As shown in fig. 20, 21 and 24, a plurality of water guide portions are provided in parallel on both sides of the drain portion 110, and the plurality of water guide portions guide water in different portions into the drain portion 110. By providing a plurality of water guides, 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 and the drain 110 as soon as possible.
It is understood that, as shown in fig. 22 and 23, at least two drain portions 110 are provided, and two or more drain portions 110 have two or more outlets 114, so that drainage is performed at a plurality of positions, which facilitates rapid drainage of water on the drain board 100. If the area of the drain plate 100 is not changed and the number of the drain portions 110 is increased, the length of the water guide portion can be shortened, and water can be rapidly introduced into the drain portions 110.
Adjacent water drainage 110 is first water drainage 111 and second water drainage 112, is equipped with the first water guide area 123 that is located one side of first water drainage 111 and the second water guide area 124 that is located one side of second water drainage 112 between first water drainage 111 and the second water drainage 112, and towards the direction of first water drainage 111, the sunken degree of depth of water guide portion of first water guide area 123 increases gradually, towards the direction of second water drainage 112, the sunken degree of depth of water guide portion of second water guide area 124 increases gradually. That is, at the butt joint position of the first water guiding area 123 and the second water guiding area 124, the depth of the water guiding portion is minimized, which facilitates the water received by the first water guiding area 123 to be guided to the first water discharging portion 111, and the water received by the second water guiding area 124 to be guided to the second water discharging portion 112, which shortens the length of the water guiding portion, and facilitates the water to be collected to the water discharging portion 110.
Of course, as shown in fig. 15, one drain 110 may be provided, and in this case, the outlet 114 of the drain 110 may be kept away from the inlet of the blower 270. Both sides of the water discharge part 110 are provided with a plurality of parallel water guide parts, which helps to shorten the water guide path of the water guide part to accelerate water discharge.

The water guide part forms an included angle of less than 7 degrees with the top surface of the drain board 100, that is, the water guide part extending obliquely is formed in the left and right direction of the drain board 100, and the angle of the water guide part does not affect the angle of the front and rear direction of the drain board 100. The water drainage part 110 extends from front to back, the water drainage part 110 forms a seventh included angle theta 3 with the horizontal plane from front to back, the seventh included angle theta 3 can influence the height change of the front and back directions of the water drainage plate 100, but integrally, the water drainage part 110 is arranged at the local position of the water drainage plate 100, the area of the water drainage plate 100 occupied by the water drainage part 110 is small, the local position inclination angle of the water drainage plate 100 is slightly large, the influence on the whole storage space in the room is small, and the indoor volume of the room can be optimized.

The first included angle alpha 1 needs to be smaller than 70 degrees so as to achieve the purpose of reducing the height; the first included angle α 1 may be less than 60 °, 50 °, 45 °, 30 °, 20 °, or 10 °, the smaller the first included angle α 1, the smaller the height direction dimension of the air duct assembly 200.
It should be noted that, when the first included angle α 1 is smaller than 7 °, the air exhaust requirement can be met, and the size of the air duct assembly 200 in the height direction is smaller, but the water guiding effect of the first cover body 241 on the surface of the fan 270 is not good, and the water discharging effect is difficult to meet the requirement. If the first included angle α 1 is less than 7 °, the problem of the fan guard 240 draining water needs to be solved.
In some cases, the first cavity 282 and the second cavity 281 are two cavities arranged in parallel in front and back; alternatively, the second cavity 281 is surrounded by the first cavity 282; the positional relationship between the first cavity 282 and the second cavity 281 is not limited to this, and the two cavities may be connected to each other. Taking the second cavity 281 as an example located behind the first cavity 282, the fan 270 may be inclined toward the front by the first included angle α 1 or inclined toward the rear by the first included angle α 1, as shown in fig. 14, the fan 270 is inclined toward the front by the first included angle α 1, and as shown in fig. 8, the fan 270 is inclined toward the rear by the first included angle α 1. That is, the upper end of the rotational axis of the fan 270 is inclined forward to form the first angle α 1 with respect to the vertical direction, or inclined backward to form the first angle α 1.
Wherein, fan 270 is upwards inclined from the front to the back gradually, that is to say the inlet of fan 270 is towards the air-out direction of first cavity 282, helps the wind in first cavity 282 to get into the inlet of fan 270, can improve ventilation effect. The fan 270 is inclined downward from the front to the rear gradually, so that the space utilization rate can be improved. In the above structure, it can be considered that the evaporator 230 and the fan 270 can share a drainage structure, so as to simplify the structure; alternatively, considering that the evaporator 230 and the fan 270 are separately provided with a drainage structure for drainage, the influence of drainage on the fan 270 may be reduced. As shown in fig. 5, 6, 12, and 13, the drain water of the evaporator 230 is guided out from the first drain parts 260 on the left and right sides, and the drain water of the fan 270 is discharged from the rear end.
It will be appreciated that the axis of rotation of the fan 270 is collinear with the central axis of the vent 244, and that the fan 270 provides a good suction effect during the process of drawing the wind in the first cavity 282 through the vent 244 into the second cavity 281, thereby contributing to the effect of the circular flow of wind in the air duct assembly 200. In some cases, the shape of the vent 244 is adapted to the shape of the inlet of the fan 270 so that wind in the first cavity 282 is drawn into the second cavity 281 by the fan 270 through the vent 244.
The axis of rotation of the fan 270 is collinear with the central axis of the vent 244, and the flow guide surface 2411 of the first cover 241 is generally disposed parallel to the fan 270, or the area of the first cover 241 corresponding to the fan 270 is disposed parallel to the fan 270. The fan 270 is typically a centrifugal fan, which changes the direction of the wind to facilitate the wind to be sent to the first compartment 410 or the second compartment 420. Of course, other fans 270 that can satisfy the effect of circulating air supply may be used.
It can be understood that, as shown in fig. 4 to 6, the first cover 241 is located above the fan 270, the first side of the flow guide surface 2411 faces away from the drainage plate 100, the second side of the flow guide surface 2411 faces towards the drainage plate 100, the first side of the flow guide surface 2411 is inclined upward by a second included angle α 2 relative to the second side of the flow guide surface 2411, i.e. in a direction away from the drainage plate 100, the flow guide surface 2411 of the first cover 241 is inclined upward by the second included angle α 2, i.e. the air outlet direction of the air vent 244 facing the first cavity 282 helps the air in the first cavity 282 to enter the second cavity 281, so that the ventilation effect can be improved, and a drainage structure shared by the evaporator 230 and the fan 270 can be considered, so as to simplify the structure. As shown in fig. 14 to 16 and 21, the air duct assembly 200 discharges water from the second or third water discharge port 2423 at the rear end.
As shown in fig. 12 to 25, when the drain plate 100 includes the water guide portion and the drain portion 110, the drain portion 110 has the outlet 114, and the water received in the drain plate 100 flows along the water guide portion to the drain portion 110 and is discharged from the outlet 114, and due to this structure, a part of the wind also flows along the water guide portion and the drain portion 110 to the outlet 114, and the outlet 114 and the vent 244 are arranged to be misaligned, so that the wind flowing in the direction of the outlet 114 is prevented from being directly discharged from the vent 244, the time for the wind to exchange heat in the first cavity 282 is prolonged as much as possible, and the heat exchange efficiency is improved. When the second cavity 281 is located behind the first cavity 282, the direction away from the drain board 100 is from the front to the back. Of course, the first cavity 282 and the second cavity 281 may be disposed left and right, and the direction away from the drain board 100 is left and right, and the working principle is consistent with the front and back direction, which is not described herein again. As shown in fig. 1 to 3, 10, 11, and 17 to 19, the second cavity 281 is located behind the first cavity 282 for example.

In some cases, second included angle α2And a third angle alpha3Is arranged at an angle alpha with respect to the first1Are identical so that the axis of rotation of the fan 270 is collinear with the central axis of the vent 244 to ensure the flow of air within the duct assembly 200 and the circulation of air within the refrigeration unit.

The top surface of the drain plate 100 is parallel to the bottom surface of the evaporator 230. Here, the evaporator 230 is placed above the drain plate 100 of fig. 1, 2, 10, and 11, but the structure of the evaporator 230 is not illustrated in the drawings.
The evaporator 230 is transverse, and it is understood that the evaporator 230 has a height less than its length and width.
The water draining plate 100 is located below the evaporator 230, the water draining plate 100 is provided with a water guiding part which is concave relative to the top surface, and an included angle between the evaporator 230 and the horizontal direction is smaller than or equal to a preset included angle.
The angle between the evaporator 230 and the horizontal direction is smaller than or equal to a predetermined angle, which can be understood as that one end of the evaporator 230 facing the air outlet is lower than one end of the evaporator 230 facing the air inlet, and a connection line between one end of the evaporator 230 facing the air outlet and one end facing the air inlet forms a predetermined angle with the horizontal plane, where the connection line can be located on the bottom surface of the evaporator 230 or a symmetrical plane in the height direction. When the evaporator 230 has a rectangular parallelepiped shape, both the bottom surface and the symmetrical plane of the evaporator 230 form a predetermined angle with the horizontal direction.
In some cases, the preset angle may be up to less than or equal to 7 °, and the preset angle may be at least one of 1 °, 2 °, 3 °, 4 °, 5 °, 6 °, and 7 °.

Alternatively, the drain plate 100 may be provided with a water guide portion recessed with respect to the top surface, and the evaporator 230 may be horizontally disposed in the first cavity 282, in which case the height of the air duct assembly 200 may be sufficiently reduced.
The included angle formed by the evaporator 230 and the horizontal direction is smaller than or equal to a preset angle, so that the height direction space occupied by the evaporator 230 is reduced, the overall height of the air duct assembly 200 can be reduced, and the purpose of expanding the capacity of the refrigeration equipment is achieved.
In combination with the drainage plate 100 shown in fig. 3 to 14, the preset angle may be 7 °, so as to meet the defrosting and drainage requirements of the evaporator 230, and reduce the overall height of the air duct assembly 200.
It can be understood that, but evaporimeter 230 horizontal installation is in drain bar 100 top, can understand that the bottom surface of evaporimeter 230 is on a parallel with the horizontal plane, for the condition that evaporimeter 230 slope set up, the required installation space's of the evaporimeter 230 of horizontal setting highly diminishes, then wind channel subassembly 200 direction of height size can diminish thereupon, and then the space in the box courage body that wind channel subassembly 200 was occupied diminishes, under the unchangeable condition of external dimension of box courage body, can effectively improve the capacity of box courage body, so as to provide the refrigeration plant of a large capacity.

It is understood that the top surface of the drain plate 100 is a plane and also parallel to the horizontal plane, that is, the bottom surface of the evaporator 230 and the top surface of the drain plate 100 are horizontally disposed. The bottom surface of the evaporator 230 is parallel to or in contact with the top surface of the drain plate 100, and the gap between the evaporator 230 and the drain plate 100 is reduced, so that the wind in the first cavity 282 is prevented from directly flowing to the ventilation opening 244 from the gap between the evaporator 230 and the drain plate 100, and the wind is assisted to exchange heat sufficiently in the first cavity 282.
It should be noted that, the gap between the evaporator 230 and the drain plate 100 is minimized, the speed of the wind flowing from the gap between the evaporator 230 and the drain plate 100 to the vent 244 is slowed down, and the staying time of the wind in the first cavity 282 is prolonged, so that the wind is fully filled in the first cavity 282 to exchange heat with the evaporator 230 and then flow out, and the heat exchange efficiency is ensured.
In the above embodiment, the evaporator 230 is a part of a refrigeration system in the refrigeration equipment, the refrigeration system includes a compressor, a condenser, a throttling element and the evaporator 230, and a refrigerant in the refrigeration system evaporates in the evaporator 230 to absorb heat, so as to provide a refrigeration environment for the wind in the first cavity 282.
The structure of the evaporator 230 will be explained. Although the evaporator 230 is mounted to the air duct assembly, the evaporator 230 is not limited to the air duct assembly 200, and may be mounted in other applicable environments.
The evaporator 230 includes a heat exchanging pipe 233 and a heat dissipating fin 234 connected to the heat exchanging pipe 233, and the heat dissipating fin 234 is configured with a ventilation portion 23421 through which the intake air of the first intake port 201 passes, so that the intake air of the first intake port 201 flows toward the inside of the evaporator 230 through the ventilation portion 23421, so that the intake air of the first intake port 201 exchanges heat sufficiently.
