Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and particularly provides an air duct machine. Background Art

[0002] At present, in order to improve the comfort of the indoor environment, the installation and use of air conditioners have become increasingly common. Among them, as a type of air conditioner indoor unit, the air duct machine has basically the same working principle as the central air conditioner, and sends air into the room by connecting the air duct. In order to improve the aesthetics after the installation of the air duct machine, the air duct machine is usually horizontally installed inside the ceiling so that the air outlet and the air inlet are roughly on the same horizontal plane.

[0003] The horizontal air duct machine in the related art includes a housing, a heat exchanger and a fan are arranged inside the housing, and a water receiving tray is arranged below the heat exchanger. The water receiving tray is used to receive the condensed water generated by the heat exchanger. Among them, an air outlet is provided on one side plate of the housing. The side plate provided with the air outlet is usually arranged horizontally or vertically. In this way, only horizontal air outlet or vertical downward air outlet can be realized, and it is very easy to directly blow the users near the air outlet. Therefore, in order to improve the comfort of the air outlet of the air duct machine and the flexibility of installation, the air duct machine needs to be able to be installed horizontally and vertically. However, when the air duct machine is installed vertically, the water receiving tray cannot receive all the condensed water generated by the heat exchanger, and this part of the condensed water is easy to flow or splash onto other components inside the air duct machine, causing problems such as rust and short circuit. Summary of the Invention

[0004] The present invention aims to solve the above technical problems, that is, to solve the problem of collecting condensed water when the air duct machine is installed vertically.

[0005] The present invention provides an air duct machine, including: a housing, internally defining a heat exchange cavity, including a first shell plate and a second shell plate connected by bending, the first shell plate is provided with an air outlet; a heat exchanger, arranged in the heat exchange cavity and obliquely extending above the second shell plate, including a heat exchange main body and a distribution pipe group, the distribution pipe group is arranged on one side in the height direction of the heat exchange main body; a vertical water receiving tray, arranged in the heat exchange cavity and fixedly connected with the housing. When the air duct machine is installed vertically, the vertical water receiving tray faces the first shell plate and is located below the distribution pipe group, and is used to receive the condensed water of the distribution pipe group.

[0006] In the case of adopting the above technical solution, after the air flows through the heat exchanger to achieve heat exchange, it flows towards the air outlet. During this process, condensed water will be generated in both the heat exchange body and the distribution pipe group. When the air duct machine is installed vertically, in order to prevent the condensed water generated by the distribution pipe group from dripping and flowing onto other components in the heat exchange cavity, a vertical water receiving tray facing the first shell plate is provided below the distribution pipe group to receive the condensed water. In this way, when the air duct machine is installed vertically, problems such as corrosion and short circuit of the devices in the heat exchange cavity caused by the condensed water generated on the distribution pipe group can be avoided, thereby improving safety.

[0007] In an alternative embodiment of the above air duct machine, the vertical water receiving tray includes: a water receiving tray body, which is located below the distribution pipe group when the air duct machine is installed vertically; a surrounding portion, which is arranged around the circumference of the water receiving tray body; and a drainage portion, which is arranged on the surrounding portion. When the air duct machine is installed vertically, the condensed water flows out through the drainage portion into the drainage component of the air duct machine.

[0008] Through the arrangement of the water receiving tray body and the surrounding portion, the condensed water of the distribution pipe group can be collected in the vertical water receiving tray. Since the vertical water receiving tray is located below the distribution pipe group and the space in the heat exchange cavity is limited, the volume of the vertical water receiving tray is limited. Through the arranged drainage portion, the collected condensed water can be discharged into the drainage component of the air duct machine, thereby preventing the condensed water from overflowing onto other devices in the heat exchange cavity and improving safety.

[0009] In an alternative embodiment of the above air duct machine, the drainage portion is an opening, and the opening is arranged facing the second shell plate.

[0010] By setting the drainage portion as an opening, the structural complexity can be reduced. The condensed water collected in the vertical water receiving tray flows out through the opening, which can prevent the condensed water in the vertical water receiving tray from overflowing. Further, the condensed water flowing out of the opening flows into the drainage component of the air duct machine.

[0011] In an alternative embodiment of the above air duct machine, the vertical water receiving tray further includes: a water guiding plate, which is arranged at the opening and extends towards the second shell along the direction away from the water receiving tray body, and the water guiding plate is used to guide the water flowing out of the drainage portion.

[0012] Through the arrangement of the water guiding plate, the condensed water can flow towards the drainage component of the air duct machine along the direction defined by the water guiding plate, so as to prevent the problem of dispersion of the condensed water affected by gravity and its own viscous force during the flowing process, and further prevent the condensed water from splashing onto other components in the heat exchange cavity.

[0013] In an alternative embodiment of the above air duct machine, the water guiding plate extends perpendicular to the water receiving tray body, or the water guiding plate extends downward obliquely along the direction towards the second shell plate.

[0014] By arranging the water guide plate perpendicular to the water receiving tray, the occupied space can be reduced; by arranging the water guide plate at an angle, not only can the flow of condensed water be guided more smoothly, reducing the impact on the water receiving parts of the duct machine, but also the splashing and deviation of condensed water can be reduced.

[0015] In an optional implementation scheme of the above-mentioned air duct machine, it also includes: a partition plate, which is arranged in the outer shell and opposite to the air outlet, the heat exchange cavity is formed between the partition plate and the first shell plate, and the partition plate is fixedly connected to the vertical water receiving tray.

[0016] By fixedly connecting the partition plate to the vertical water receiving pan, the structural stability and safety of the vertical water receiving pan can be improved when the duct air conditioner is installed vertically.

[0017] In an optional implementation scheme of the above-mentioned duct air conditioner, it also includes: a horizontal water receiving pan, which is arranged on the second shell plate and is located between the first shell plate and the partition plate; when the duct air conditioner is installed vertically or horizontally, the horizontal water receiving pan is located below the heat exchanger and receives condensed water from the heat exchanger; when the duct air conditioner is installed vertically, the horizontal water receiving pan is partially located below the heat exchanger and receives condensed water from the heat exchange body.

[0018] When the duct unit is installed horizontally, the horizontal water tray is located below the heat exchanger to receive the condensed water generated by the heat exchanger body and the distribution pipe group; when the duct unit is installed vertically, the horizontal water tray is located below the heat exchanger to receive the condensed water generated by the heat exchanger body, and in conjunction with the vertical water tray set below the distribution pipe group, it can prevent the condensed water from splashing or dripping onto the components in the shell as much as possible. By setting the horizontal water tray and the vertical water tray, horizontal and vertical installations can be performed according to actual needs, which improves installation flexibility while improving the safety and reliability of the duct unit operation.

[0019] In an optional implementation scheme of the above-mentioned duct dryer, the horizontal water receiving tray includes: a chassis main body, which is arranged on the second shell plate, and the heat exchanger is arranged on the chassis main body; a peripheral portion, which is arranged around the chassis main body and extends in a direction away from the second shell plate; an auxiliary tray body, which is arranged on the side of the peripheral portion opposite to the air outlet, and the auxiliary tray body extends obliquely toward the air outlet in a direction away from the chassis main body; when the duct dryer is installed vertically, the bottom end of the heat exchanger is located between the chassis main body and the auxiliary tray body, and the water outlet end of the water guide plate is located between the auxiliary tray body and the chassis main body.

[0020] Through the cooperation of the chassis main body and the peripheral part, it can ensure the collection of the condensed water generated by the heat exchanger when the air duct machine is installed horizontally. Further, when the air duct machine is installed vertically, the bottom end of the heat exchanger is located between the auxiliary tray body and the chassis main body, and the condensed water generated by the heat exchange main body can flow along the surface to the bottom end. Through the cooperation of the auxiliary tray body, the chassis main body and the peripheral part, the condensed water generated by the heat exchange main body can be collected. In addition, the auxiliary tray body can block the condensed water to avoid the overflow of the condensed water and improve the collection capacity of the condensed water at this time. At the same time, such an arrangement can also collect the condensed water led out by the water guide plate.

[0021] In an alternative embodiment of the above air duct machine, the horizontal water receiving tray further includes: a partition strip, which is disposed on the chassis main body close to the auxiliary tray body and extends along the length direction of the second shell plate. The partition strip abuts against the bottom end of the heat exchanger and divides the horizontal water receiving tray into a first water receiving part and a second water receiving part. When the air duct machine is installed horizontally or vertically, the first water receiving part and the second water receiving part receive the condensed water of the heat exchanger. When the air duct machine is installed vertically, the second water receiving part receives the condensed water of the heat exchange main body and the condensed water led out by the water guide plate.

[0022] Through the setting of the partition strip, on the one hand, it can support the heat exchanger arranged obliquely and improve the installation performance of the heat exchanger; on the other hand, it can divide the chassis main body into a first water receiving part and a second water receiving part. Among them, when the air duct machine is installed horizontally, the first water receiving part and the second water receiving part jointly receive the condensed water of the heat exchanger. When the air duct machine is installed vertically, the second water receiving part is located below the heat exchange main body to realize the collection of the condensed water of the heat exchange main body and the condensed water led out by the water guide plate.

[0023] In an alternative embodiment of the above air duct machine, the peripheral part is provided with a drain hole, and the drain hole is correspondingly arranged for the second water receiving part.

[0024] Through the setting of the drain hole, when an external drain pipe is connected, the collected condensed water can be led out. Since the drain hole is correspondingly arranged for the second water receiving part, it can prevent the condensed water from overflowing into the heat exchange cavity due to excessive condensed water volume whether the air duct machine is installed horizontally or vertically.

[0043] Combined with Figures 1 to 9 As shown, the present invention provides an air duct machine, which includes a housing 10, a heat exchanger 20, a horizontal water receiving tray 40, and a vertical water receiving tray 30.

[0044] An inner heat exchange cavity 103 is defined inside the housing 10, which includes a first shell plate 11 and a second shell plate 12 that are bent and connected. The first shell plate 11 is provided with an air outlet 101; the heat exchanger 20 is arranged in the heat exchange cavity 103 and extends obliquely above the second shell plate 12. The heat exchanger 20 includes a heat exchange main body 21 and a distribution pipe group 22. The distribution pipe group 22 is arranged on one side in the height direction of the heat exchange main body 21; the vertical water receiving tray 30 is arranged in the heat exchange cavity 103 and fixedly connected to the housing 10. When the air duct machine is installed vertically, the vertical water receiving tray 30 faces the first shell plate 11 and is located below the distribution pipe group 22 for receiving the condensed water of the distribution pipe group 22.

[0045] Optionally, a heat exchange chamber 103 and a blower chamber 104 that communicate with each other are formed inside the housing 10. Among them, the housing 10 includes a first shell plate 11 and a second shell plate 12 corresponding to the heat exchange chamber 103. The heat exchanger 20 is disposed obliquely in the heat exchange chamber 103 and is arranged above the second shell plate 12. An air outlet 101 is provided on the first shell plate 11, and an air inlet 102 is provided on a third plate body of the housing 10 opposite to the first shell plate 11. The blower chamber 104 and the heat exchange chamber 103 are arranged in sequence and are located between the air inlet 102 and the air outlet 101. A blower is provided in the blower chamber 104. Driven by the blower, indoor air flows into the housing 10 through the air inlet 102, and further exchanges heat through the heat exchanger 20. The air that has achieved heat exchange flows into the indoor environment through the air outlet 101.

[0046] Optionally, the top end of the heat exchanger 20 is arranged close to the air outlet 101, and the bottom end extends obliquely towards the second shell plate 12. That is, the bottom end of the heat exchanger 20 is far from the air outlet 101. In this way, whether the air duct machine is installed horizontally or vertically, air can pass through the heat exchanger 20 to ensure the heat exchange effect.

[0047] Optionally, the heat exchanger 20 is a plate heat exchanger.

[0048] Optionally, the heat exchanger 20 includes a heat exchange main body 21 and a distribution pipe group 22. Specifically, the heat exchange main body 21 includes heat exchange tubes and heat exchange fins sleeved on the heat exchange tubes. The distribution pipe group 22 includes a liquid distributor, a liquid collector, and connecting pipes for connecting the heat exchange tubes to the liquid distributor / liquid collector.

[0049] When the air duct machine is installed vertically, during its operation, condensed water will also be generated on the surface of the distribution pipe group 22. In order to prevent the condensed water from dripping onto other components in the heat exchange chamber 103, a vertical water receiving tray 30 facing the first shell plate 11 is provided below the distribution pipe group 22. In this way, the collection of condensed water can be ensured, and the splashing of condensed water can be avoided.

[0050] Optionally, the vertical water receiving tray 30 is fixed to the housing 10 to ensure the stability after installation.

[0051] In the case of adopting the above technical solution, after air flows through the heat exchanger 20 to achieve heat exchange, it flows towards the air outlet 101. During this process, condensed water will be generated on both the heat exchange main body 21 and the distribution pipe group 22. When the air duct machine is installed vertically, in order to prevent the condensed water generated by the distribution pipe group 22 from dripping and flowing onto other components in the heat exchange chamber 103, a vertical water receiving tray 30 facing the first shell plate 11 is provided below the distribution pipe group 22 to receive the condensed water. In this way, when the air duct machine is installed vertically, problems such as corrosion and short circuit of the devices inside the heat exchange chamber 103 caused by the condensed water generated on the distribution pipe group 22 can be avoided, thereby improving safety.

[0052] In the alternative implementation of the above air duct unit, the vertical water receiving tray 30 includes a water receiving tray body 31, a surrounding portion 32, and a drainage portion 33. When the air duct unit is installed vertically, the water receiving tray body 31 is located below the distribution pipe group 22. The surrounding portion 32 is arranged around the circumference of the water receiving tray body 31. The drainage portion 33 is arranged on the surrounding portion 32. When the air duct unit is installed vertically, the condensed water flows out through the drainage portion 33 into the drainage member of the air duct unit.

[0053] Specifically, through the cooperation of the water receiving tray body 31 and the surrounding portion 32, a vertical water receiving tray 30 with an open mouth can be formed, and the open mouth faces the distribution pipe group 22. The condensed water generated by the distribution pipe group 22 drips into the space surrounded by the surrounding portion 32 inside the vertical water receiving tray 30 through the open mouth. Further, limited by the space in the heat exchange cavity 103, the volume of the vertical water receiving tray 30 cannot be too large. Therefore, the amount of condensed water received by the vertical water receiving tray 30 is limited. In order to prevent the condensed water from overflowing too much and corroding or short-circuiting the devices (the devices mentioned here include structural parts or components) in the heat exchange cavity 103, a drainage portion 33 is opened on the surrounding portion 32. When the air duct unit is installed vertically, the condensed water in the vertical water receiving tray 30 is led out to the drainage member of the air duct unit through the arranged drainage portion 33, and is discharged to the outside of the housing 10 or other positions where condensed water is required through the drainage member.

[0054] Alternatively, an electric heating element is provided inside the water receiving tray body 31 or on the side surface facing away from the distribution pipe group 22. The electric heating element can be energized to heat the water receiving tray body when the air duct unit is turned off, so as to prevent bacteria from growing when the water receiving tray body 31 is in a wet state. Or the electric heating element can be energized to heat the water receiving tray body 31 to evaporate the received condensed water when there is a large amount of condensed water. Optionally, the electric heating element is an electric heating wire or an electric heating sheet, etc.

[0055] Alternatively, no electric heating element is provided.

[0056] In this solution, through the arrangement of the water receiving tray body 31 and the surrounding portion 32, the condensed water of the distribution pipe group 22 can be collected in the vertical water receiving tray 30. Since the vertical water receiving tray 30 is located below the distribution pipe group 22 and the volume in the heat exchange cavity 103 is limited, the volume of the vertical water receiving tray 30 is limited. Through the arranged drainage portion 33, the collected condensed water can be discharged to the drainage member of the air duct unit, thereby preventing the condensed water from overflowing onto other devices inside the heat exchange cavity 103 and improving safety.

[0057] In the alternative implementation of the above air duct unit, the drainage portion 33 is an opening, and the opening faces the second shell plate 12.

[0058] By setting the drainage part 33 to be open and facing the second shell plate 12, the structure is simple and easy to process. That is, by setting the drainage part 33 to be open, the complexity of the structure can be reduced, and the condensed water collected in the vertical water receiving tray 30 flows out through the opening, which can prevent the condensed water in the vertical water receiving tray from overflowing. Further, the condensed water flowing out of the opening flows into the drainage part of the air duct machine.

[0059] Optionally, the height of the opening is the same as the height of the enclosure part 32 to prevent condensed water from accumulating on the water receiving tray body 31 and causing the problem of bacterial growth, and to improve the cleanliness of the internal environment of the heat exchange cavity 103.

[0060] Alternatively, the height of the opening is less than the height of the enclosure part 32. In one case, the opening is provided at one end of the enclosure part 32 away from the water receiving tray body 31. In this way, the condensed water can slowly overflow from the drainage part 33 when a certain amount of condensed water is stored, which can prevent the splashing of the condensed water. In another case, the opening is provided at one end of the enclosure part 32 connected to the water receiving tray body 31. In this way, the structural strength of the enclosure part 32 can be ensured.

[0061] Optionally, when the air duct machine is installed vertically, the water receiving tray body 31 extends towards the second shell plate 12 and slopes downwards to facilitate the flow of condensed water towards the opening and improve the efficiency of guiding the condensed water to the horizontal water receiving tray 40.

[0062] Alternatively, when the air duct machine is installed vertically, the water receiving tray body 31 extends horizontally.

[0063] In the optional implementation of the above air duct machine, the vertical water receiving tray 30 further includes a water guiding plate 34. The water guiding plate 34 is arranged at the drainage part 33 and extends towards the second shell plate 12 along the direction away from the water receiving tray body 31.

[0064] In this solution, by arranging the water guiding plate 34, the condensed water can flow towards the drainage part of the air duct machine along the direction defined by the water guiding plate 34, so as to prevent the condensed water from being dispersed under the influence of gravity and its own viscous force during the flowing process, and further prevent the condensed water from splashing onto other components in the heat exchange cavity 103.

[0065] Optionally, the water guiding plate 34 is arranged in a flat plate shape.

[0066] Alternatively, the surface of the water guiding plate 34 facing the distribution pipe group is a water guiding surface, and this surface is arranged as a corrugated surface to slow down the flowing speed of the condensed water and reduce the impact of the condensed water on the horizontal water receiving tray 40.

[0067] Alternatively, the water guiding plate 34 is not provided.

[0068] In the optional implementation of the above air duct machine, the water guide plate 34 extends perpendicular to the downward water receiving tray body 31, or the water guide plate 34 extends downward obliquely along the direction towards the second housing plate 12.

[0069] By setting the water guide plate 34 perpendicular to the water receiving tray body 31, the occupied space can be reduced.

[0070] By setting the water guide plate 34 to be arranged obliquely downward, not only can the flow of condensed water be guided more gently, reducing the impact on the lateral water receiving tray 40, but also the splashing and deviation of condensed water can be reduced.

[0071] Optionally, the surface of the water guide plate 34 is coated with a hydrophobic coating. By setting the hydrophobic coating on the surface of the water guide plate 34, the flow resistance of condensed water can be reduced, the fluidity of condensed water can be improved, and the retention of condensed water on the surface of the water guide plate 34 can be avoided.

[0072] Alternatively, no hydrophobic coating is provided on the surface of the water guide plate 34.

[0073] In the optional implementation of the above air duct machine, it further includes a partition plate 13. The partition plate 13 is arranged inside the housing and is arranged opposite to the air outlet 101. A heat exchange chamber 103 is formed between the partition plate 13 and the first housing plate 11, and the partition plate 13 is fixedly connected to the vertical water receiving tray 30.

[0074] By fixedly connecting the partition plate 13 to the vertical water receiving tray 30, the structural stability and safety of the vertical water receiving tray 30 can be improved when the air duct machine is installed vertically.

[0075] Optionally, the partition plate 13 is located between the air outlet 101 and the air inlet 102 to partition out the heat exchange chamber 103 and the fan chamber 104. Optionally, a fan is provided in the fan chamber 104, and through holes for docking the fan outlet of the fan are provided on the partition plate 13. In this way, the communication between the heat exchange chamber 103 and the fan chamber 104 can be achieved.

[0076] Optionally, the partition plate 13 is fixedly connected to the housing 10 and can be used to fix the vertical water receiving tray 30, wherein the vertical water receiving tray 30 is fixedly connected to the partition plate 13 and the housing 10 simultaneously.

[0077] Alternatively, the vertical water receiving tray 30 is only fixedly connected to the housing 10, or the vertical water receiving tray 30 is only fixedly connected to the partition plate 13.

[0078] In the optional implementation of the above air duct machine, it further includes a lateral water receiving tray 40. The lateral water receiving tray 40 is arranged on the second housing plate 12. When the air duct machine is installed vertically or horizontally, the lateral water receiving tray 40 receives the condensed water of the heat exchanger 20. When the air duct machine is installed vertically, the lateral water receiving tray 40 receives the condensed water of the heat exchange main body 21.

[0079] Optionally, since the heat exchanger 20 is disposed obliquely, and the transverse water receiving tray 40 is disposed on the second housing plate 12. In the case where the air duct unit is installed horizontally, the second housing plate 12 extends in the horizontal direction, and the transverse water receiving tray 40 is located below the overall heat exchanger 20, that is, the orthographic projection of the heat exchanger 20 towards the second housing plate 12 is completely located within the transverse water receiving tray 40. Thus, the transverse water receiving tray 40 can receive the condensed water generated by the heat exchanger 20.

[0080] Optionally, in the case where the air duct unit is installed vertically, the second housing plate 12 extends in the vertical direction, and the transverse water receiving tray 40 is partially located below the heat exchanger 20, that is, the orthographic projection of the heat exchanger 20 in the vertical direction is partially located within the transverse water receiving tray 40. Since the volume of the liquid distributor / collector is relatively large and is usually located in the middle in the height direction of the heat exchange body, it cannot be projected into the transverse water receiving tray 40. Therefore, at this time, a part of the heat exchange body 21 is projected into the transverse water receiving tray 40.

[0081] Optionally, the transverse water receiving tray 40 is detachably connected to the second housing plate 12.

[0082] Alternatively, the transverse water receiving tray 40 is formed on the second housing plate 12, that is, integrally formed with the second housing plate 12.

[0083] In the optional implementation of the above air duct unit, the transverse water receiving tray 40 includes a chassis main body 41, a peripheral portion 42, and an auxiliary tray body 43. The chassis main body 41 is disposed on the second housing plate 12, and the heat exchanger 20 is disposed on the chassis main body 41. The peripheral portion 42 is disposed around the chassis main body 41 and extends in a direction away from the second housing plate 12. The auxiliary tray body 43 is disposed on a side of the peripheral portion 42 opposite to the air outlet 101, and the auxiliary tray body 43 extends obliquely towards the air outlet 101 in a direction away from the chassis main body 41.

[0084] When the air duct unit is installed vertically, the bottom end of the heat exchanger 20 is located between the chassis main body 41 and the auxiliary tray body 43, and the water outlet end 341 of the water guide plate 34 is located between the auxiliary tray body 43 and the chassis main body 41.

[0085] Optionally, the peripheral portion 42 is disposed around the periphery of the chassis main body 41 to define a water receiving space located above the chassis main body 41.

[0086] Optionally, the chassis main body 41 is arranged parallel to the second shell plate 12. When the air duct machine is installed horizontally, the heat exchanger 20 is located above the chassis main body 41. At this time, the orthographic projection of the heat exchanger 20 on the chassis main body 41 is completely located within the water receiving space, so as to be able to receive the condensed water of the overall heat exchanger 20. Since the heat exchanger 20 is inclined towards the air outlet 101 in the direction away from the chassis main body 41, when the air duct machine is installed vertically, a part of the orthographic projection of the heat exchanger 20 on the plane of the peripheral part 42 below it is located on the peripheral part 42. At this time, the condensed water can flow downward along the surface of the heat exchanger 20 and flow into the transverse water receiving tray 40 along the edge at the bottom end of the heat exchanger 20.

[0087] Optionally, on the side of the peripheral part 42 opposite to the air outlet 101, there is an auxiliary tray body 43. The auxiliary tray body 43 extends obliquely towards the air outlet 101 in the direction away from the chassis main body 41. In this way, when the air duct machine is installed vertically, the received condensed water can be blocked to increase the receiving volume.

[0088] Optionally, the included angle between the heat exchanger 20 and the chassis main body 41 is greater than or equal to 30° and less than or equal to 60°. Specifically, when the air duct machine is installed vertically, the chassis main body 41 is installed horizontally. At this time, if the included angle between the heat exchanger 20 and the chassis main body 41 is greater than 60°, the flow resistance of the air passing through the heat exchanger 20 increases, which is not conducive to the heat exchange of the heat exchanger 20; if the included angle between the heat exchanger 20 and the chassis main body 41 is less than 30°, the condensed water will not flow to the edge line at the bottom end of the heat exchanger 20 and will directly drip along the surface of the heat exchanger 20, thus flowing to other positions in the heat exchange cavity 103, causing problems such as component corrosion or short circuit.

[0089] Optionally, the end of the water receiving tray body 31 facing the second shell plate 12 is located between the auxiliary tray body 43 and the chassis main body 41.

[0090] Optionally, in order to ensure the drainage of the condensed water in the vertical water receiving tray 30 to the transverse water receiving tray 40, the water outlet end 341 of the water guiding plate 34 is located between the auxiliary tray body 43 and the chassis main body 41. Further, the water outlet end 341 is lower than the top end of the auxiliary tray body 43.

[0091] Optionally, when the air duct machine is installed vertically, the water outlet end 341 of the water guiding plate 34 extends downward to extend into the water receiving space above the transverse water receiving tray 40, so as to realize the diversion of the condensed water.

[0092] Among them, the water outlet end 341 of the water guiding plate 34 is the end away from the water receiving tray body 31.

[0093] In this solution, through the cooperation of the chassis main body 41 and the peripheral part 42, it is possible to ensure the collection of the condensed water generated by the heat exchanger 20 when the air duct machine is installed horizontally. Further, when the air duct machine is installed vertically, the bottom end of the heat exchanger 20 is located between the auxiliary disk body 43 and the chassis main body 41, and the condensed water generated by the heat exchange main body 21 can flow along the surface to the bottom end. Through the cooperation of the auxiliary disk body 43, the chassis main body 41, and the peripheral part 42, the condensed water generated by the heat exchange main body 21 can be collected. In addition, the auxiliary disk body 43 can block the condensed water to prevent the overflow of the condensed water and improve the collection capacity of the condensed water at this time. At the same time, such an arrangement can also collect the condensed water led out by the water guide plate 34.

[0094] In an alternative implementation of the above air duct machine, the horizontal water receiving tray 40 further includes a partition strip 44. The partition strip 44 is disposed on the chassis main body 41 close to the auxiliary disk body 43 and extends along the length direction of the second shell plate 12. The partition strip 44 abuts against the bottom end of the heat exchanger 20 and divides the water receiving space of the horizontal water receiving tray 40 into a first water receiving portion 401 and a second water receiving portion 402. When the air duct machine is installed horizontally or vertically, the first water receiving portion 401 and the second water receiving portion 402 receive the condensed water of the heat exchanger 20. When the air duct machine is installed vertically, the second water receiving portion 402 receives the condensed water of the heat exchange main body 21 and the condensed water led out by the water guide plate 34.

[0095] Optionally, the side surface of the partition strip 44 facing the air outlet 101 is defined as the abutting side surface, and the abutting side surface faces the auxiliary disk body 400 and extends obliquely away from the chassis main body 41. The abutting side surface abuts against the bottom side surface of the bottom end of the heat exchanger 20, so that while the partition strip 44 can separate the first water receiving portion 401 and the second water receiving portion 402, it can also support the heat exchanger 20 and improve the installation stability of the heat exchanger 20.

[0096] Optionally, the extending direction of the partition strip 44 is the same as the length direction of the heat exchanger 20.

[0097] Optionally, the length of the partition strip 44 is equal to the length of the heat exchanger 20.

[0098] Alternatively, the length of the partition strip 44 is less than the length of the heat exchanger 20 to facilitate the flow of the condensed water in the first water receiving portion 401 to the second water receiving portion 402.

[0099] Optionally, the partition strip 44 is integrally formed with the chassis main body 41.

[0100] In this solution, through the setting of the partition strip 44, on the one hand, it can support the inclined heat exchanger 20 and improve the safety of the heat exchanger 20; on the other hand, it can divide the chassis main body 41 into a first water receiving part 401 and a second water receiving part 402. When the air duct machine is installed horizontally, the first water receiving part 401 and the second water receiving part 402 jointly receive the condensed water of the heat exchanger 20; when the air duct machine is installed vertically, the second water receiving part 402 is located below the heat exchange main body 21 to collect the condensed water of the heat exchange main body 21 and the condensed water discharged by the water guide plate 34.

[0101] When the air duct machine is installed horizontally, the second shell plate 12 is horizontally arranged, and the air can be regarded as flowing horizontally and then flowing through the inclined heat exchanger 20 towards the air outlet 101. The flowing air may drive the condensed water on the surface of the heat exchanger 20 to fly away from the heat exchanger 20. However, the bottom end of the heat exchanger 20 faces away from the air outlet 101, that is, it is close to the air inflow direction, and the top end is close to the air outlet 101. During the air flow, the condensed water close to the horizontal water receiving tray 40 (that is, the condensed water flying away from the bottom end of the heat exchanger 20) will fall onto the horizontal water receiving tray 40, and the condensed water close to the air outlet 101 (that is, the condensed water flying away from the top end of the heat exchanger 20) will leave the heat exchange cavity. When the air duct machine is installed vertically, the air flows towards the chassis main body 41 and the air outlet 101, which can avoid the splashing of condensed water.

[0102] In the optional implementation of the above air duct machine, the peripheral part 42 is provided with a drain hole 45, and the drain hole 45 is arranged corresponding to the second water receiving part 402.

[0103] Through the setting of the drain hole 45, when an external drain pipe is connected, the collected condensed water can be discharged; since the drain hole 45 is arranged corresponding to the second water receiving part 402, it can prevent the condensed water from overflowing into the heat exchange cavity 103 whether the air duct machine is installed horizontally or vertically.

[0104] Through the setting of the drain hole 45, the collected condensed water can be discharged. Since the drain hole 45 is arranged corresponding to the second water receiving part 402, it can ensure the timely discharge of condensed water whether the air duct machine is installed horizontally or vertically. When the vertical water receiving tray 30 drains water to the horizontal water receiving tray 40, it can also prevent the overflow of condensed water.

[0105] Optionally, the surface of the heat exchanger 20 is coated with a hydrophilic coating.

[0106] By providing a hydrophilic coating on the surface of the heat exchanger 20, the generated condensed water can flow along the surface of the heat exchanger 20 and then flow to the bottom end of the heat exchanger 20, avoiding the splashing of the condensed water; further, in the case of vertical installation of the air duct machine, it is ensured that the condensed water flows to the bottom edge of the heat exchanger 20 and then drips into the horizontal water receiving tray 40, improving the collection effect of the condensed water.

[0107] Specifically, the hydrophilic coating includes one or more of an organic-inorganic hydrophilic coating film containing silicon, hydrophilic modified silica, titanium dioxide, and hydrophilic resin. Among them, the hydrophilic resin can provide the durability of the hydrophilic coating.

[0108] Alternatively, the surface of the heat exchanger 20 is not coated with a hydrophilic coating.

However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of the present invention.
