Description

Technical Field

[0001] The invention relates to the technical field of air conditioning, and in particular to an air duct unit. Background Art

[0002] Duct air conditioner is the abbreviation of hidden air conditioner, which can also be called air conditioner duct air conditioner or duct air conditioner. Duct air conditioner is usually installed inside the ceiling, which does not occupy indoor space and can improve the utilization rate of indoor space.

[0003] The duct air conditioner usually includes a housing, a fan, a heat exchanger and a water tray. The housing has an installation cavity, and the fan, the heat exchanger and the water tray are arranged in the installation cavity. The housing is provided with an air inlet and an air outlet. The airflow attracted by the fan enters the installation cavity through the air inlet and is discharged through the air outlet. The heat exchanger is located at the air outlet and is used to exchange heat with the air in the installation cavity. The water tray is used to collect condensed water generated during the operation of the heat exchanger.

[0004] In the related art, the water tray includes a bottom plate and a side plate, the side plate is arranged around the circumference of the bottom plate, and the side plate and the bottom plate form a receiving cavity. The heat exchanger is arranged on the bottom plate and is located in the receiving cavity. However, there is a gap between the heat exchanger and the bottom plate, and part of the airflow attracted by the fan will flow to the air outlet through the gap, resulting in poor heat exchange efficiency of the duct air conditioner. Summary of the invention

[0005] An embodiment of the present invention provides a duct air conditioner, which can improve the heat exchange efficiency of the duct air conditioner.

[0006] To achieve the above object, the embodiments of the present invention adopt the following technical solutions:

[0007] In a first aspect, an embodiment of the present application provides an air duct unit, which includes a housing, a fan, a heat exchanger, and a water tray.

[0008] The shell has an installation cavity, and an air inlet and an air outlet are provided on the shell. The fan is arranged in the installation cavity, and the airflow attracted by the fan enters the installation cavity through the air inlet and is discharged through the air outlet. The heat exchanger is arranged in the installation cavity, and is used to perform heat exchange with the air in the installation cavity. The water receiving pan is arranged in the installation cavity, and has a receiving cavity. The heat exchanger is located in the receiving cavity, and the receiving cavity is used to collect condensed water generated during the operation of the heat exchanger. The water receiving pan includes a bottom plate and a side plate, and the side plate is arranged around the circumference of the bottom plate, and the side plate and the bottom plate enclose a receiving cavity.

[0009] The bottom plate includes a mounting portion and a drainage portion. The surface of the mounting portion close to the heat exchanger is the mounting surface, which is a plane, and the heat exchanger is arranged on the mounting surface. The drainage portion is arranged on the side of the mounting portion away from the air outlet and is connected to the mounting portion. The surface of the drainage portion close to the heat exchanger is located on the side of the mounting surface away from the heat exchanger. Along the arrangement direction of the mounting portion and the drainage portion, and from the mounting portion to the drainage portion, the distance between the surface of the drainage portion close to the heat exchanger and the mounting surface gradually increases, which is used to guide the condensed water in the accommodating cavity to the end of the drainage portion away from the mounting portion.

[0010] It is understandable that setting the heat exchanger on a plane can make the surface of the heat exchanger fit better with the plane. Based on this, setting the mounting surface as a plane and setting the heat exchanger on the mounting surface can make the surface of the heat exchanger close to the mounting surface fit better with the mounting surface. In this way, the risk of a gap between the heat exchanger and the base plate can be reduced, thereby reducing the risk of the airflow attracted by the fan flowing through the gap to the air outlet, so that the airflow attracted by the fan can flow more through the heat exchanger and be discharged from the air outlet after exchanging heat with the heat exchanger. In this way, the heat exchange efficiency of the duct air conditioner can be improved.

[0011] In addition, the drainage portion can guide the condensed water in the accommodating cavity to an end of the drainage portion away from the mounting portion. In this way, the condensed water in the accommodating cavity can be concentrated together, making it easier to discharge the condensed water in the accommodating cavity.

[0012] In some embodiments, the bottom plate further includes an air supply unit. The air supply unit is disposed on a side of the mounting portion close to the air outlet and connected to the mounting portion. The surface of the air supply unit close to the heat exchanger is located on a side of the mounting surface close to the heat exchanger. Along the arrangement direction of the mounting portion and the air supply unit, and from the mounting portion to the air supply unit, the distance between the surface of the air supply unit close to the heat exchanger and the mounting surface gradually increases.

[0013] In some embodiments, the drainage portion has a first end and a second end opposite to each other, and the first end and the second end are two ends of the drainage portion in a first direction. The first direction is parallel to the mounting surface and perpendicular to the arrangement direction of the mounting portion and the drainage portion. Along the first direction, and from the first end to the second end, the distance between the surface of the drainage portion close to the heat exchanger and the mounting surface gradually increases, so as to guide the condensed water in the accommodating cavity to the second end.

[0014] In some embodiments, the drainage portion includes a first sub-portion and a second sub-portion. The second sub-portion is disposed on one side of the first sub-portion in the first direction and is connected to the first sub-portion. The first direction is parallel to the mounting surface and perpendicular to the arrangement direction of the mounting portion and the drainage portion. Along the first direction, and from the first sub-portion to the second sub-portion, the distance between the surface of the first sub-portion close to the heat exchanger and the mounting surface gradually decreases, and the distance between the surface of the second sub-portion close to the heat exchanger and the mounting surface gradually increases, so as to guide the condensed water in the accommodating cavity to the two ends of the first sub-portion and the second sub-portion that are far away from each other.

[0015] In some embodiments, a drainage hole is provided on the water receiving tray, and the drainage hole is connected to the accommodating cavity for draining the condensed water in the accommodating cavity.

[0016] In some embodiments, a guide channel is formed on the drainage part, and the guide channel is formed by a portion of the surface of the drainage part close to the heat exchanger being recessed in a direction away from the heat exchanger, and the guide channel is located at the connection between the drainage part and the side plate. The guide channel is connected to the drainage hole, and is used to guide the condensed water in the accommodating cavity to the drainage hole.

[0017] In some embodiments, the drainage hole is disposed on the side plate, close to one end of the accommodating cavity, and at least partially located on a side of the flow guiding channel away from the heat exchanger.

[0018] In some embodiments, there are two water receiving pans, and the two water receiving pans are arranged at intervals along a first direction. The first direction is parallel to the mounting surface and perpendicular to the arrangement direction of the mounting portion and the drainage portion. There are two heat exchangers, each heat exchanger corresponds to a water receiving pan, and the heat exchanger is located in the accommodating cavity of the corresponding water receiving pan.

[0019] In some embodiments, the duct air conditioner further comprises a chassis and a drain pipe. The chassis is arranged in the installation cavity and is located between the two water receiving trays. The chassis has a water collecting cavity, and the drain hole is connected to the water collecting cavity, and is used to discharge the condensed water in the accommodating cavity into the water collecting cavity. The drain pipe is connected to the water collecting cavity, and is used to discharge the condensed water in the water collecting cavity.

[0020] In a second aspect, an embodiment of the present application provides an air duct unit, which includes a housing, a fan, a heat exchanger, and a water tray.

[0021] The shell has an installation cavity, and an air inlet and an air outlet are provided on the shell. The fan is arranged in the installation cavity, and the airflow attracted by the fan enters the installation cavity through the air inlet and is discharged through the air outlet. The heat exchanger is arranged in the installation cavity, and is used to perform heat exchange with the air in the installation cavity. The water collecting pan is arranged in the installation cavity, and has a accommodating chamber. The heat exchanger is located in the accommodating chamber, and the accommodating chamber is used to collect condensed water generated during the operation of the heat exchanger. The water collecting pan includes a bottom plate and a side plate, the side plate is arranged around the circumference of the bottom plate, and the side plate and the bottom plate form an accommodating chamber. Among them, the bottom plate includes a mounting portion and a drainage portion. The surface of the mounting portion close to the heat exchanger is a mounting surface, the mounting surface is a plane, and the heat exchanger is arranged on the mounting surface. The drainage portion is arranged on a side of the mounting portion away from the air outlet, and is connected to the mounting portion, and is used to guide the condensed water in the accommodating chamber to an end of the drainage portion away from the mounting portion.

[0022] The beneficial effects of the duct air conditioner provided in the second aspect are the same as the beneficial effects of the duct air conditioner provided in the first aspect, and will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] Duct air conditioner is a concealed air conditioner, usually installed inside the ceiling, to solve the problem of wall mounted and cabinet air conditioners being exposed outside and affecting the appearance. In addition, duct air conditioner does not occupy indoor space, which is conducive to improving the utilization rate of indoor space.

[0050] At present, the duct air conditioner usually includes a housing, a fan, a heat exchanger and a water tray. The housing has an installation cavity, and the fan, the heat exchanger and the water tray are arranged in the installation cavity. Among them, the housing is provided with an air inlet and an air outlet. The airflow attracted by the fan enters the installation cavity through the air inlet and is discharged from the air outlet. The heat exchanger is located at the air outlet and is used to exchange heat with the air in the installation cavity. The water tray is arranged on the lower side of the heat exchanger to collect condensed water generated during the operation of the heat exchanger.

[0051] In related technologies, such as Figure 1 As shown, Figure 1The structure diagram of the water receiving tray and the heat exchanger provided in the related art. The water receiving tray 001 includes a bottom plate 011 and a side plate 012, and the side plate 012 is arranged around the circumference of the bottom plate 011, and forms a receiving cavity 013 with the bottom plate 011. The heat exchanger 002 is arranged on the bottom plate 011 and is located in the receiving cavity 013. Among them, when the air duct machine is in the state of being installed, the surface of the bottom plate 011 close to the heat exchanger 002 is usually an inclined surface intersecting with the horizontal plane, so that the condensed water in the receiving cavity is concentrated together, which provides convenience for the discharge of the condensed water; and the surface of the heat exchanger 002 close to the bottom plate 011 is a plane parallel to the horizontal plane. In this way, a gap 014 will be generated between the heat exchanger and the bottom plate, and part of the airflow attracted by the fan will flow to the air outlet through the gap 014 and be discharged through the air outlet, causing the air supply of the heat exchanger 002 to short-circuit. It is understandable that the part of the airflow flowing toward the air outlet through the gap 014 cannot exchange heat with the heat exchanger 002 very well, resulting in poor heat exchange efficiency of the duct air conditioner.

[0052] Based on this, see Figure 2 , Figure 2 The present invention provides a structure diagram of a duct air conditioner according to an embodiment of the present invention. The present invention provides a duct air conditioner 100, which can improve the heat exchange efficiency of the duct air conditioner 100.

[0053] like Figure 3 As shown, Figure 3 The structure diagram of a duct air conditioner provided in an embodiment of the present application is shown in FIG. The duct air conditioner 100 comprises a housing 1 and a fan 2 , wherein the housing 1 has an installation cavity 11 , and the fan 2 is disposed in the installation cavity 11 .

[0054] It should be noted that the housing 1 is provided with an air inlet 12 and an air outlet 13, and both the air inlet 12 and the air outlet 13 are connected to the installation cavity 11. On this basis, the airflow attracted by the fan 2 can enter the installation cavity 11 through the air inlet 12 and be discharged through the air outlet 13.

[0055] It can be understood that the fan 2 can accelerate the flow of air, thereby promoting the circulation of air between the installation cavity 11 and the room.

[0056] Exemplarily, the fan 2 is a centrifugal fan 2 .

[0057] Among them, see Figure 4 , Figure 4 The fan 2 has a volute 21, an impeller and a motor 22. The volute 21 is provided with an air inlet 211 (such as Figure 3 As shown) and the air outlet 212 (as shown Figure 3 As shown in FIG. 2 , the impeller is disposed in the volute 21 and is connected to the motor 22 .

[0058] In this way, when the motor 22 rotates, the impeller can be driven to rotate, so that air enters the volute 21 from the air inlet 211 and is discharged from the air outlet 212, thereby forming an airflow.

[0059] Among them, see Figure 3 The air duct machine 100 may further include a first partition plate 3, which is located in the installation cavity 11 and connected to the housing 1, and divides the installation cavity 11 into an air inlet cavity 111 and an air outlet cavity 112. The air inlet 12 and the air outlet 13 are located on opposite sides of the first partition plate 3, and the air inlet 12 is connected to the air inlet cavity 111, and the air outlet 13 is connected to the air outlet cavity 112.

[0060] On this basis, the first partition plate 3 is provided with a vent 31, which is used to connect the air inlet cavity 111 and the air outlet cavity 112. In this case, the airflow attracted by the fan 2 can enter the air inlet cavity 111 through the air inlet 12, flow into the air outlet cavity 112 through the vent 31, and finally be discharged through the air outlet 13. At this time, the air inlet 211 on the volute 21 can be connected to the vent 31 to make the airflow flow smoother.

[0061] It should be noted that, when the installation cavity 11 is divided into the air inlet cavity 111 and the air outlet cavity 112, the fan 2 can be arranged in the air inlet cavity 111 to shorten the distance between the fan 2 and the air inlet 12. In this way, when the fan 2 is running, the suction force at the air inlet 12 can be increased, and the speed at which the indoor air flows into the installation cavity 11 can be accelerated.

[0062] See also Figure 3 The air duct machine 100 provided in the embodiment of the present application further includes a heat exchanger 4 , which is disposed in the installation cavity 11 and is used for performing heat exchange with the air in the installation cavity 11 .

[0063] In this way, the airflow attracted by the fan 2 can exchange heat with the heat exchanger 4 when passing through the heat exchanger 4, and then flow into the room through the air outlet 13, thereby achieving the adjustment of the indoor temperature.

[0064] Among them, see Figure 5 , Figure 5 A structural diagram of a heat exchanger provided in an embodiment of the present application. The heat exchanger 4 may include a refrigerant tube 41 and fins 42, and the refrigerant tube 41 is in contact with the fins 42. In this way, when the refrigerant flows in the refrigerant tube 41, heat exchange can be performed with the air in the installation cavity 11 through the tube wall of the refrigerant tube 41 and the fins 42, thereby cooling or heating the air in the installation cavity 11.

[0065] For example, Figure 3As shown, when the installation cavity 11 is divided into the air inlet cavity 111 and the air outlet cavity 112, the heat exchanger 4 is arranged in the air outlet cavity 112. At this time, the airflow attracted by the fan 2 can enter the air inlet cavity 111 through the air inlet 12, and flow into the air outlet cavity 112 through the vent 31, and after exchanging heat with the heat exchanger 4 in the air outlet cavity 112, it is discharged through the air outlet 13.

[0066] It is understandable that when the duct unit 100 is used to cool the indoor air, the water vapor in the air may be cooled on the surface of the heat exchanger 4 to form condensed water. Figure 3 The air duct machine 100 provided in the embodiment of the present application may further include a water receiving tray 5 for collecting condensed water.

[0067] Among them, Figure 3 As shown, the water receiving pan 5 is arranged in the installation cavity 11 and has a receiving cavity 51, which is used to collect condensed water generated during the operation of the heat exchanger 4. On this basis, the heat exchanger 4 can be arranged in the receiving cavity 51 to collect the condensed water generated during the operation of the heat exchanger 4.

[0068] It should be noted that, when the heat exchanger 4 is disposed in the air outlet cavity 112 , the water receiving tray 5 is also disposed in the air outlet cavity 112 .

[0069] For example, Figure 6 As shown, Figure 6 The structure diagram of a water receiving tray provided in an embodiment of the present application. The water receiving tray 5 includes a bottom plate 52 and a side plate 53. The side plate 53 is arranged around the circumference of the bottom plate 52, and the side plate 53 and the bottom plate 52 enclose a receiving cavity 51. In this case, the heat exchanger 4 (such as Figure 5 As shown) is disposed on the base plate 52 and connected to the base plate 52.

[0070] Among them, see Figure 7 , Figure 7 A structural diagram of a water tray and a heat exchanger provided in an embodiment of the present application. The bottom plate 52 includes a mounting portion 521, and the surface of the mounting portion 521 close to the heat exchanger 4 is a mounting surface 5211, the mounting surface 5211 is a plane, and the heat exchanger 4 is arranged on the mounting surface 5211. It should be noted that the mounting surface 5211 is a plane, which means that when the duct machine 100 is in a state of being installed, the mounting surface 5211 is perpendicular to the direction of gravity, that is, the mounting surface 5211 is parallel to the horizontal plane.

[0071] It is understandable that arranging the heat exchanger 4 on a plane can make the surface of the heat exchanger 4 fit better with the plane. Based on this, setting the mounting surface 5211 as a plane and arranging the heat exchanger 4 on the mounting surface 5211 can make the surface of the heat exchanger 4 close to the mounting surface 5211 fit better with the mounting surface 5211.

[0072] In this way, the risk of a gap between the heat exchanger 4 and the bottom plate 52 can be reduced, thereby reducing the risk of the airflow attracted by the fan 2 flowing to the air outlet 13 through the gap, so that the airflow attracted by the fan 2 can flow more through the heat exchanger 4, and after exchanging heat with the heat exchanger 4, it is discharged from the air outlet 13. In this way, the heat exchange efficiency of the air duct unit 100 can be improved.

[0073] It should be noted that if Figure 7 As shown, the bottom plate 52 may further include a drainage portion 522, which is disposed at the mounting portion 521 away from the air outlet 13 (eg, Figure 3 As shown in the figure), and connected to the mounting portion 521.

[0074] The surface of the drainage portion 522 close to the heat exchanger 4 is located on the side of the installation surface 5211 away from the heat exchanger 4. That is, when the air duct unit 100 is in the installed state, the surface of the drainage portion 522 close to the heat exchanger 4 is located on the lower side of the installation surface 5211, that is, the surface of the drainage portion 522 close to the heat exchanger 4 is located on the side of the installation surface 5211 close to the center of the earth.

[0075] In this way, the condensed water in the accommodating chamber 51 can be preferentially concentrated on the drainage portion 522, thus reducing the risk of the heat exchanger 4 being soaked by the condensed water. In this way, the risk of the heat exchanger 4 being corroded can be reduced, thereby extending the service life of the heat exchanger 4.

[0076] In addition, in some embodiments of the present application, the drainage portion 522 can guide the condensed water in the accommodating cavity 51 to an end of the drainage portion 522 away from the mounting portion 521. In this way, the condensed water in the accommodating cavity 51 can be concentrated together, making it easier to discharge the condensed water in the accommodating cavity 51.

[0077] For example, Figure 7 As shown, along the arrangement direction X of the mounting portion 521 and the drainage portion 522, and from the mounting portion 521 to the drainage portion 522, the distance between the surface of the drainage portion 522 close to the heat exchanger 4 and the mounting surface 5211 gradually increases. That is, along the arrangement direction X of the mounting portion 521 and the drainage portion 522, the closer the point on the surface of the drainage portion 522 close to the heat exchanger 4 is to the mounting portion 521, the higher its horizontal position is.

[0078] In this way, the condensed water in the accommodating cavity 51 can flow to the end of the drainage portion 522 away from the mounting portion 521 under the action of gravity, and then be concentrated at the end of the drainage portion 522 away from the mounting portion 521, providing convenience for the discharge of the condensed water.

[0079] It is understandable that a recessed portion may be provided at one end of the drainage portion 522 away from the mounting portion 521, and a guide groove may be provided on the surface of the drainage portion 522 close to the heat exchanger 4, and the guide groove is used to guide the condensed water in the accommodating cavity 51 to the recessed portion. In this way, the condensed water in the accommodating cavity 51 can also be concentrated at one end of the drainage portion 522 away from the mounting portion 521. The specific selection can be made according to actual conditions, and this application does not make specific restrictions on this.

[0080] Some embodiments of the present application are schematically described below by taking the example that the distance between the surface of the drainage portion 522 close to the heat exchanger 4 and the mounting surface 5211 gradually increases along the arrangement direction X of the mounting portion 521 and the drainage portion 522, and from the mounting portion 521 to the drainage portion 522.

[0081] In some embodiments, see Figure 8 , Figure 8 The structure diagram of a water receiving tray provided in an embodiment of the present application. The drainage portion 522 has a first end 5221 and a second end 5222 opposite to each other. The first end 5221 and the second end 5222 are two ends of the drainage portion 522 in the first direction Y. It should be noted that the first direction Y is parallel to the mounting surface 5211 (such as Figure 7 As shown) and perpendicular to the arrangement direction X of the mounting portion 521 and the drainage portion 522.

[0082] Among them, see Fig. 9 , Fig. 9 A method provided in the embodiment of the present application Figure 8 Along the first direction Y, and from the first end 5221 to the second end 5222, the drainage portion 522 is close to the heat exchanger 4 (such as Figure 7 ) and the mounting surface 5211 (as shown Figure 7 That is, along the first direction Y, the closer the point on the surface of the drainage portion 522 close to the heat exchanger 4 is to the second end 5222, the lower its horizontal position is.

[0083] In this way, the condensed water in the accommodating cavity 51 can flow toward the second end 5222 under the action of gravity, and then be concentrated at the second end 5222, which facilitates the discharge of the condensed water.

[0084] It is understandable that if Fig.10 As shown, Fig.10 A method provided in the embodiment of the present application Figure 8Along the first direction Y, and from the first end 5221 to the second end 5222, the distance between the surface of the drainage portion 522 close to the heat exchanger 4 and the mounting surface 5211 can also be set to remain unchanged.

[0085] In addition, if Fig.11 As shown, Fig.11 A method provided in the embodiment of the present application Figure 8 Along the first direction Y, and from the first end 5221 to the second end 5222, the distance between the surface of the drainage portion 522 close to the heat exchanger 4 and the mounting surface 5211 can also be set to gradually decrease. The specific selection can be made according to actual conditions, and this application does not make specific restrictions on this.

[0086] In other embodiments, see Fig.12 , Fig.12 A method provided in the embodiment of the present application Figure 8 The drainage portion 522 includes a first sub-portion 5223 and a second sub-portion 5224. The second sub-portion 5224 is disposed on one side of the first sub-portion 5223 in the first direction Y and is connected to the first sub-portion 5223.

[0087] Along the first direction Y, and from the first sub-section 5223 to the second sub-section 5224, the first sub-section 5223 is close to the heat exchanger 4 (such as Figure 7 ) and the mounting surface 5211 (as shown Figure 7 As shown in the figure, the distance between the first sub-section 5223 and the second sub-section 5224 gradually decreases, and the distance between the surface of the second sub-section 5224 close to the heat exchanger 4 and the mounting surface 5211 gradually increases. That is, along the first direction Y, the closer the point on the surface of the drainage portion 522 close to the heat exchanger 4 is to the end where the first sub-section 5223 and the second sub-section 5224 are close to each other, the higher its horizontal position is.

[0088] In this case, the condensed water in the accommodating cavity 51 can flow to the two ends of the first sub-section 5223 and the second sub-section 5224 far away from each other under the action of gravity, and then concentrate at the two ends of the first sub-section 5223 and the second sub-section 5224 far away from each other, providing convenience for the discharge of the condensed water.

[0089] It is understandable that the condensed water can be pumped out of the accommodating chamber 51 by setting up a drainage pump and a drainage pipe to discharge the condensed water in the accommodating chamber 51; other methods can also be used to discharge the condensed water in the accommodating chamber 51. The specific method can be selected according to actual conditions, and this application does not make any specific restrictions on this.

[0090] For example, Fig.13 As shown, Fig.13 A method provided in the embodiment of the present application Figure 8The water receiving tray 5 is provided with a drainage hole 54, which is communicated with the accommodating chamber 51 and is used to discharge the condensed water in the accommodating chamber 51. Arranged in this way, the structure is simple and easy to implement.

[0091] The drainage holes 54 may be disposed on the bottom plate 52 or on the side plate 53 , and the specific selection may be made according to actual conditions, and this application does not make any specific limitation on this.

[0092] See also Fig.14 , Fig.14 A method provided in the embodiment of the present application Figure 8 In the case where the water receiving tray 5 is provided with a drain hole 54, a guide channel 55 may also be provided on the drain portion 522. The guide channel 55 is formed by a portion of the surface of the drain portion 522 close to the heat exchanger 4 being recessed in a direction away from the heat exchanger 4. The guide channel 55 is connected to the drain hole 54 and is used to guide the condensed water in the accommodating cavity 51 to the drain hole 54.

[0093] It can be understood that the provision of the guide channel 55 is conducive to draining all the condensed water in the accommodating cavity 51 through the drainage hole 54 , thereby reducing the risk of residual condensed water in the accommodating cavity 51 .

[0094] It should be noted that the guide channel 55 can be set at the connection between the drainage part 522 and the side plate 53, and can also be set at other positions. The specific selection can be made according to actual conditions, and this application does not make any specific restrictions on this.

[0095] For example, Fig.14 As shown, the guide channel 55 is arranged at the connection between the drainage portion 522 and the side plate 53.

[0096] On this basis, the drainage hole 54 is arranged on the side plate 53, and one end of the drainage hole 54 close to the accommodating cavity 51 is at least partially located in the guide channel 55 away from the heat exchanger 4 (such as Figure 7 That is to say, the lowest point of the end of the drain hole 54 close to the accommodating cavity 51 is lower than the lowest point of the guide channel 55, which is conducive to draining the condensed water in the guide channel 55.

[0097] It is understandable that the lowest point of the drainage hole 54 at one end close to the accommodating cavity 51 may also be flush with the lowest point of the guide channel 55. The specific selection can be made according to actual conditions, and the present application does not make any specific limitation on this.

[0098] See also Figure 7 The bottom plate 52 of the water receiving tray 5 provided in the embodiment of the present application may further include an air supply portion 523, which is disposed near the air outlet 13 (such as Figure 3521 and is connected to the mounting portion 521. When the bottom plate 52 includes the air supply portion 523, the mounting portion 521 and the drainage portion 522, the mounting portion 521 is located between the air supply portion 523 and the drainage portion 522, and opposite ends of the mounting portion 521 are connected to the air supply portion 523 and the drainage portion 522, respectively.

[0099] The surface of the air supply part 523 close to the heat exchanger 4 is located on the side of the installation surface 5211 close to the heat exchanger 4. That is, when the air duct unit 100 is in the installed state, the surface of the air supply part 523 close to the heat exchanger 4 is located on the upper side of the installation surface 5211, that is, the surface of the air supply part 523 close to the heat exchanger 4 is located on the side of the installation surface 5211 away from the center of the earth.

[0100] On this basis, along the arrangement direction of the mounting portion 521 and the air supply portion 523 (eg Figure 7 The X direction is shown in FIG. 5 , and the distance between the surface of the air supply portion 523 close to the heat exchanger 4 and the mounting surface 5211 gradually increases from the mounting portion 521 to the air supply portion 523. That is, along the arrangement direction of the mounting portion 521 and the air supply portion 523, the closer the point on the surface of the air supply portion 523 close to the heat exchanger 4 is to the mounting portion 521, the lower its horizontal position is.

[0101] In this way, the condensed water falling on the air supply portion 523 can flow to the installation portion 521 under the action of gravity, and flow to the drainage portion 522 through the installation portion 521, and finally gather at the end of the drainage portion 522 away from the installation portion 521, providing convenience for the discharge of the condensed water.

[0102] In some embodiments, see Fig.15 , Fig.15 A structural diagram of a duct air conditioner provided in an embodiment of the present application. The duct air conditioner 100 includes a plurality of water receiving trays 5 and a plurality of heat exchangers 4, each heat exchanger 4 corresponds to a water receiving tray 5, and the heat exchanger 4 is located in the accommodating cavity 51 of the corresponding water receiving tray 5. The plurality of heat exchangers 4 are arranged in parallel.

[0103] Arranged in this way, it is convenient to independently control the heat exchanger 4. In this case, any one or more heat exchangers 4 can be selected to work to adjust the indoor temperature.

[0104] It should be noted that if Fig.16 As shown, Fig.16A structural diagram of a heat exchanger, an air collecting pipe, a liquid distributor, a main air pipe, a main liquid pipe, and a throttling device provided in an embodiment of the present application. In the case where the heat exchanger 4 includes a refrigerant pipe 41 and a fin 42, the air duct unit 100 may also include an air collecting pipe 6 and a liquid distributor 7, one end of the refrigerant pipe 41 is connected to the air collecting pipe 6, and the other end is connected to the liquid distributor 7. By providing the air collecting pipe 6 and the liquid distributor 7, it is convenient to evenly distribute the refrigerant to multiple heat exchangers 4, which is conducive to improving the heat exchange efficiency of the air duct unit 100.

[0105] On this basis, the duct air conditioner 100 further includes a main air pipe 8 and a main liquid pipe 9. The main air pipe 8 is connected to the air collecting pipe 6, the main liquid pipe 9 is connected to the liquid distributor 7, and a throttling device 10 is provided on the main liquid pipe 9. The throttling device 10 may be an electronic expansion valve.

[0106] For example, Fig.15 As shown, the number of the water trays 5 and the number of the heat exchangers 4 are both two. On this basis, the air duct unit 100 may further include two second partitions 20. The two second partitions 20 are located in the air outlet cavity 112 and are spaced apart along the first direction Y.

[0107] Among them, the two second partitions 20 are connected to the first partition 3 and the shell 1 to divide the air outlet cavity 112 into a first sub-cavity 1121, a second sub-cavity 1122 and a third sub-cavity 1123, and the second sub-cavity 1122 is located between the first sub-cavity 1121 and the third sub-cavity 1123.

[0108] In this case, the first sub-cavity 1121 and the third sub-cavity 1123 are both connected to the vent 31 (eg Figure 3 As shown) and the air outlet 13 is connected (as shown Figure 3 For example, the vent 31 includes two sub-vents 31, and the two sub-vents 31 are connected to the first sub-cavity 1121 and the third sub-cavity 1123 respectively; the air outlet 13 includes two sub-air outlets 13, and the two sub-air outlets 13 are connected to the first sub-cavity 1121 and the third sub-cavity 1123 respectively.

[0109] At this time, the fan 2 may include two volutes 21 , each volute 21 corresponds to a sub-ventilation opening 31 , and the air outlet 212 of the volute 21 is connected to the corresponding sub-ventilation opening 31 .

[0110] For example, Fig.15 As shown, a heat exchanger 4 and a water receiving tray 5 are respectively provided in the first sub-chamber 1121 and the third sub-chamber 1123 .

[0111] In this way, when the indoor temperature is adjusted by using the duct fan 100, the temperature of different indoor areas can be adjusted by selecting different fans 2 to work. In this way, the indoor temperature can be adjusted in different zones.

[0112] See also Fig.17 , Fig.17 The structure diagram of a duct machine provided in an embodiment of the present application. When the number of the water receiving trays 5 and the number of the heat exchangers 4 are both two, the duct machine 100 may further include a chassis 30, which is arranged in the installation cavity 11 (such as Figure 3 As shown in FIG. 1 , the bottom plate 30 is disposed in the second sub-cavity 1122 and between the two water receiving trays 5. For example, when the air outlet cavity 112 is divided into the first sub-cavity 1121, the second sub-cavity 1122 and the third sub-cavity 1123, the bottom plate 30 is disposed in the second sub-cavity 1122.

[0113] The bottom plate 30 has a water collecting cavity, a drainage hole 54 (such as Fig.14 The condensed water in the receiving chamber 51 can be discharged into the water collecting chamber through the drainage hole 54. At this time, the drainage hole 54 can be arranged on the side of the water receiving tray 5 close to the bottom plate 30, so as to facilitate the communication between the drainage hole 54 and the water collecting chamber.

[0114] It is understandable that the drainage hole 54 can be directly connected to the water collection chamber, for example, the water collection chamber has an opening, and one end of the drainage hole 54 away from the accommodating chamber 51 is located at the opening of the water collection chamber; the drainage hole 54 can also be connected to the water collection chamber through a pipeline. The specific selection can be made according to actual conditions, and this application does not make specific limitations on this.

[0115] It should be noted that the duct air conditioner 100 may further include a drain pipe, which is connected to the water collecting chamber, and the condensed water in the water collecting chamber can be discharged through the drain pipe.

[0117] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
