Description

Technical Field

[0001] This utility model relates to the field of air handling equipment technology, and in particular to a duct air handling unit and an air conditioning unit. Background Technology

[0002] In traditional buildings, the living room and dining room are two independent yet interconnected spaces, both requiring heat exchange and air supply. Current ducted air conditioning systems can only direct airflow in one direction. Users can only place the system in the dining room to supply air to the living room, resulting in poor airflow in that area due to the distance between the system and the living room. Alternatively, placing the system in the living room to supply air to the dining room also results in poor airflow in that area. Both placement options lead to poor airflow performance. Furthermore, these location limitations restrict the placement of the ducted air conditioning system and also affect the building's interior design, impacting the user experience. Utility Model Content

[0003] To address the technical problem that existing ducted air conditioners can only supply air in one direction, thus affecting the air supply effect and user experience, a ducted air conditioner and air conditioning unit is provided that has a first air outlet, a second air outlet, and a third air outlet with different air outlet directions on the housing to achieve multi-zone air supply and ensure air supply effect.

[0004] A ducted air conditioner, comprising:

[0005] case;

[0006] A partition is disposed inside the housing, and the partition divides the interior of the housing into a heat exchange chamber and a fan chamber. An air vent is provided on the partition, and the heat exchange chamber can communicate with the fan chamber through the air vent.

[0007] The heat exchange chamber is provided with a first air outlet, and the fan chamber is provided with a second air outlet, a third air outlet and a fourth air outlet. The first air outlet can discharge air to a first side of the shell, the second air outlet can discharge air to a second side of the shell, the third air outlet can discharge air to a third side of the shell, and the fourth air outlet can supply air to the fan chamber.

[0008] The ducted air conditioner has a first side air outlet mode, a second side air outlet mode, and a third side air outlet mode;

[0009] When the duct unit is in the first side air outlet mode, the first air outlet serves as the airflow outlet and the fourth air outlet serves as the airflow inlet.

[0010] When the duct unit is in the second side air outlet mode, the second air outlet serves as the air outlet, the first air outlet serves as the air inlet, and the third and fourth air outlets are in a closed state.

[0011] When the ducted air conditioner is in the third side air outlet mode, the third air outlet serves as the air outlet, the first air outlet serves as the air inlet, and the second and fourth air outlets are in a closed state.

[0012] The duct air handling unit also includes a fan, which is disposed inside the fan cavity, and the air inlet includes a first air inlet and a second air inlet;

[0013] When the ducted air conditioner is in the first side air outlet mode, the inlet of the fan is connected to the fourth air outlet, and the outlet of the fan is connected to the heat exchange chamber through the first air outlet.

[0014] When the ducted air conditioner is in the second side air outlet mode, the inlet of the fan is connected to the second air outlet and the heat exchange chamber, and the outlet of the fan is connected to the second air outlet.

[0015] When the ducted air conditioner is in the third side air outlet mode, the inlet of the fan is connected to the second air outlet and the heat exchange chamber, and the outlet of the fan is connected to the third air outlet.

[0016] The fan has a first inlet and a second inlet. The first inlet is connected to the second air outlet, and the second inlet is connected to the fourth air outlet.

[0017] The duct unit also includes a valve assembly, and the first air inlet, the second air inlet, the second air outlet, the third air outlet, and the fourth air outlet are all equipped with the valve assembly.

[0018] The air valve assembly includes a drive mechanism and multiple air guide blades. All the air guide blades are arranged side by side and are connected to the drive mechanism. The drive mechanism can move all the air guide blades to adjust the spacing between two adjacent air guide blades.

[0019] The ducted air handling unit also includes a flow guiding structure, which is disposed inside the fan cavity. The flow guiding inlet of the flow guiding structure is connected to the outlet of the fan. The flow guiding structure has three flow guiding outlets, one of which is connected to the first air outlet, one of which is connected to the second air outlet, and one of which is connected to the third air outlet.

[0020] The number of fans is two, and the two fans are arranged side by side in the fan cavity, and the second air outlet and the fourth air outlet are both arranged corresponding to the fans.

[0021] The first air inlet, the second air inlet, and the third air inlet are all located between the two fans.

[0025] The ducted air conditioner and air conditioning unit provided by this utility model, by setting a first air outlet, a second air outlet, and a third air outlet with different air outlet directions on the casing, enables the ducted air conditioner to deliver air in three directions. When this application is used between the dining room and the living room, different air outlets can be used to deliver air to the dining room and the living room. In addition, the third air outlet is set to further increase the air delivery direction of the ducted air conditioner, so that the ducted air conditioner can deliver air to different areas. In particular, the third air outlet is set on the lower surface of the ducted air conditioner. When the ducted air conditioner is heating, the heating air can be delivered through the third air outlet, so that the hot air can be blown to the bottom surface quickly, improving the heating effect of the ducted air conditioner. Moreover, the fourth air outlet allows the ducted air conditioner to take in air without using the second and third air outlets when the air is exiting through the first air outlet. This eliminates the need for the fan inside the ducted air conditioner to reverse or move, reduces the air reversal time of the ducted air conditioner and the noise that may be caused by the fan movement during air reversal, and further improves the air delivery effect of the ducted air conditioner and the user experience.

[0039] In traditional buildings, the living room and dining room are two independent yet interconnected spaces, both requiring heat exchange and air supply. Existing ducted air conditioning systems can only direct airflow in one direction. Users can only place the system in the dining room to supply air to the living room, resulting in poor airflow in that area due to the distance between the system and the living room. Alternatively, placing the system in the living room to supply air to the dining room also results in poor airflow in that area due to the distance between the system and the dining room. Both placement options lead to poor airflow performance. Furthermore, these location limitations restrict the placement of the ducted air conditioning system and also limit the building's interior design, impacting the user experience. Therefore, this application provides a... Figures 1 to 6The ducted air conditioner shown includes: a housing 1; a partition 2, which is disposed inside the housing 1 and divides the interior of the housing 1 into a heat exchange chamber 11 and a fan chamber 12. The partition 2 is provided with an air outlet, and the heat exchange chamber 11 can communicate with the fan chamber 12 through the air outlet. The heat exchange chamber 11 is provided with a first air outlet 13, and the fan chamber 12 is provided with a second air outlet 14, a third air outlet 15, and a fourth air outlet 16. The first air outlet 13 can discharge air to a first side of the housing 1, the second air outlet 14 can discharge air to a second side of the housing 1, the third air outlet 15 can discharge air to a third side of the housing 1, and the fourth air outlet 16 can supply air to the fan chamber 12. By setting a first air outlet 13, a second air outlet 14, and a third air outlet 15 with different air outlet directions on the housing 1, the duct air conditioner can achieve air supply in three directions. When this application is used between the dining room and the living room, different air outlets can be used to supply air to the dining room and the living room. In addition, the third air outlet 15 is set to further increase the air supply direction of the duct air conditioner, so that the duct air conditioner can supply air to different areas. In particular, the third air outlet 15 is set on the lower surface of the duct air conditioner. When the duct air conditioner is heating, the heating air can be supplied through the third air outlet 15, so that the hot air can be blown to the bottom surface quickly, improving the heating effect of the duct air conditioner. Moreover, the fourth air outlet 16 is set so that the duct air conditioner can take in air without using the second air outlet 14 and the third air outlet 15 when the air is discharged from the first air outlet 13. This eliminates the need for the fan inside the duct air conditioner to reverse or move, reduces the air reversal time of the duct air conditioner and the noise that may be caused by the movement of the fan when the air is reversing, and further improves the air supply effect of the duct air conditioner and the user experience.

[0040] The ducted air conditioner has a first side air outlet mode, a second side air outlet mode, and a third side air outlet mode;

[0041] When the ducted air conditioner is in the first side air outlet mode, the first air outlet 13 serves as the air outlet and the fourth air outlet 16 serves as the air inlet. The gas outside the housing 1 enters the fan chamber 12 through the fourth air outlet 16, and then enters the heat exchange chamber 11 through the partition 2 under the action of the fan in the fan chamber 12. After heat exchange with the heat exchanger in the heat exchange chamber 11, the gas is finally discharged through the first air outlet 13, thereby achieving the effect of the ducted air conditioner supplying air to the first side.

[0042] When the ducted air conditioner is in the second side air outlet mode, the second air outlet 14 serves as the air outlet, the first air outlet 13 serves as the air inlet, and the third air outlet 15 and the fourth air outlet 16 are in a closed state. Since the second air outlet 14, the third air outlet 15, and the fourth air outlet 16 are all connected to the fan chamber 12, when the second air outlet 14 supplies air, in order to ensure that the airflow reliably passes through the heat exchanger, the gas needs to enter the heat exchange chamber 11 from the first air outlet 13, and then exchange heat through the heat exchanger in the heat exchange chamber 11 before passing through the partition 2 and entering the fan chamber 12. Under the action of the fan in the fan chamber 12, the gas is discharged through the second air outlet 14. At this time, the third air outlet 15 and the fourth air outlet 16 are kept closed, restricting the gas in the fan chamber 12 to be discharged only through the second air outlet 14, thereby achieving the effect of the ducted air conditioner supplying air to the second side.

[0043] When the ducted air conditioner is in the third-side air outlet mode, the third air outlet 15 serves as the air outlet, the first air outlet 13 serves as the air inlet, and the second air outlet 14 and the fourth air outlet 16 are in a closed state. Since the second air outlet 14, the third air outlet 15, and the fourth air outlet 16 are all connected to the fan chamber 12, when the third air outlet 15 supplies air, in order to ensure that the airflow reliably passes through the heat exchanger, the gas needs to enter the heat exchange chamber 11 from the first air outlet 13, and after heat exchange in the heat exchange chamber 11, it passes through the partition 2 and enters the fan chamber 12. Under the action of the fan in the fan chamber 12, it is discharged through the third air outlet 15. At this time, the second air outlet 14 and the fourth air outlet 16 are kept closed, restricting the gas in the fan chamber 12 to be discharged only through the third air outlet 15, thereby achieving the effect of the ducted air conditioner supplying air to the third side.

[0044] The ducted air conditioner also includes a fan 3, which is disposed in the fan chamber 12. The air outlets include a first air outlet 21 and a second air outlet 22. By setting a fourth air outlet 16 and a second air outlet 22, the fan 3 can switch between connecting to the outside of the housing 1 and connecting to the heat exchange chamber 11 without reversing or moving. Only the opening and closing states of the fourth air outlet 16 and the second air outlet 22 need to be controlled, which reduces the air outlet reversal time of the ducted air conditioner and also reduces the noise caused by the fan 3 needing to move to change the airflow direction, thereby improving the air delivery effect and user experience of the ducted air conditioner. The working states of the first air outlet 21 and the second air outlet 22 are opposite, so that only unidirectional gas flow can occur between the heat exchange chamber 11 and the fan chamber 12.

[0045] When the ducted air conditioner is in the first side air outlet mode, the inlet of the fan 3 is connected to the fourth air outlet 16, and the outlet of the fan 3 is connected to the heat exchange chamber 11 through the first air passage 21. The second air passage 22 is in a closed state. At this time, the air outlet of the fan 3 can only flow into the heat exchange chamber 11 through the first air passage 21. Since the second air passage 22 is in a closed state, the fan 3 cannot obtain gas from the heat exchange chamber 11 through the second air passage 22 to ensure the normal operation of the ducted air conditioner. At this time, the gas outside the casing 1 (indoors) flows back into the room through the fourth air outlet 16, the inlet of the fan 3, the outlet of the fan 3, the first air passage 21, the heat exchange chamber 11 and the first air outlet 13 in sequence, completing the heat exchange process of the first side air supply.

[0046] When the ducted air conditioner is in the second side air outlet mode, the inlet of the fan 3 is connected to the second air outlet 22 and the heat exchange chamber 11, and the outlet of the fan 3 is connected to the second air outlet 14. The first air outlet 21 is in a closed state. Since the first air outlet 21 is in a closed state, the fan 3 can only obtain gas from the heat exchange chamber 11 through the second air outlet 22. The fan 3 cannot obtain gas from outside the housing 1 through the first air outlet 21, thus ensuring the normal operation of the ducted air conditioner. At this time, the gas outside the housing 1 (indoors) flows back into the room through the first air outlet 13, the heat exchange chamber 11, the second air outlet 22, the inlet of the fan 3, the outlet of the fan 3, and the second air outlet 14, completing the heat exchange process of the second side air supply.

[0047] When the ducted air conditioner is in the third side air outlet mode, the inlet of the fan 3 is connected to the second air outlet 22 and the heat exchange chamber 11, and the outlet of the fan 3 is connected to the third air outlet 15. The first air outlet 21 is in a closed state. Since the first air outlet 21 is in a closed state, the fan 3 can only obtain gas from the heat exchange chamber 11 through the second air outlet 22. The fan 3 cannot obtain gas from outside the housing 1 through the first air outlet 21, ensuring the normal operation of the ducted air conditioner. At this time, the gas outside the housing 1 (indoors) flows back into the room through the first air outlet 13, the heat exchange chamber 11, the second air outlet 22, the inlet of the fan 3, the outlet of the fan 3 and the third air outlet 15 in sequence, completing the heat exchange process of the second side air supply.

[0048] Preferably, the inlet of the fan 3 includes a first inlet and a second inlet. The first inlet is interconnected with the second air outlet 22, and the second inlet is interconnected with the fourth air outlet 16. That is, the first inlet corresponds to the second air outlet 22. In this case, the first inlet can only obtain airflow from the second air outlet 22, and the second inlet corresponds to the fourth air outlet 16, ensuring that the fan 3 can provide normal airflow drive according to the working requirements of the duct machine, thereby ensuring the working reliability of the duct machine. Preferably, as... Figure 1As shown, the projection of the first inlet on the partition 2 is within the range of the second air outlet 22, ensuring reliable communication between the first inlet and the second air outlet. A flow guide pipe can be set between the first inlet and the second air outlet 22 for flow guidance. The projection of the second inlet on the housing 1 is within the range of the fourth air outlet 16, ensuring reliable communication between the second inlet and the fourth air outlet 16. A flow guide pipe can be set between the second inlet and the fourth air outlet 16 for flow guidance.

[0049] Among them, the fan 3 is a centrifugal fan. The first inlet and the second inlet are formed at both ends of the volute of the centrifugal fan, and the outlet of the fan 3 is formed on the side wall of the volute. At this time, the fan 3 can be arranged on one side of the partition 2, and the rotation axis of the fan 3 is perpendicular to the partition 2. At this time, the plane where the first inlet is located can be parallel to the plane where the partition 2 is located, ensuring that the first inlet and the second air outlet 22 correspond reliably. The housing 1 has a side that is parallel to the partition 2 and forms part of the side wall of the fan cavity 12. The fourth air outlet 16 can be arranged on this side to facilitate the arrangement of the fan 3, the second air outlet 22 and the fourth air outlet 16.

[0050] The ducted air handling unit also includes a damper assembly 4. The first air inlet 21, the second air inlet 22, the second air outlet 14, the third air outlet 15, and the fourth air outlet 16 are all equipped with the damper assembly 4. By switching the state of the damper assembly 4, the state of the first air inlet 21, the second air inlet 22, the second air outlet 14, the third air outlet 15, and the fourth air outlet 16 can be switched, thereby achieving reliable control of the air inlet and outlet direction of the ducted air handling unit.

[0051] In one embodiment, the air valve assembly 4 includes a drive mechanism 42 and multiple guide vanes 41. All guide vanes 41 are arranged side-by-side and connected to the drive mechanism 42. The drive mechanism 42 can move all guide vanes 41 to adjust the spacing between adjacent guide vanes 41. When the air valve assembly 4 is switched to the closed state, all guide vanes 41 are laid flat on the same plane or adjacent guide vanes 41 overlap and seal each other, thereby closing the opening of the air valve assembly 4. When the air valve assembly 4 is switched to the open state, the spacing between the guide vanes 41 increases, allowing gas to flow through the spacing, thereby opening the opening of the air valve assembly 4. The drive mechanism 42 is a stepper motor. Stepper motors drive the guide vanes 41 with low noise, and the centrifugal fan does not need to stop operating during the airflow direction change process of the duct unit, avoiding the noise caused by the fan 3 needing to move to change the airflow direction, and eliminating the waiting time of the fan 3 stopping during the change process. The 41-blade air guide opens and closes to change the air direction, solving the problems of long air direction change time and high noise, and achieving imperceptible steering.

[0052] The damper assembly 4 also includes a connecting rod, which is connected to the drive mechanism 42. All the air guide vanes 41 are connected to the connecting rod. The driving force of the drive mechanism 42 can drive the connecting rod to move, thereby achieving the purpose of adjusting all the air guide vanes 41 at the same time and ensuring the working reliability of the damper assembly 4.

[0053] Preferably, during the process of switching the air valve assembly 4 from the closed state to the open state, the rotation angle of the air guide vane 41 is 90°. At this time, the air guide vane 41 has the weakest ability to block the airflow, thereby avoiding the air valve assembly 4 from blocking the airflow.

[0054] The ducted air conditioner also includes a flow guiding structure, which is disposed within the fan cavity 12. The flow guiding inlet of the flow guiding structure is connected to the outlet of the fan 3. The flow guiding structure has three flow guiding outlets, one of which is connected to the first air passage 21, one of which is connected to the second air outlet 14, and one of which is connected to the third air outlet 15. The flow guiding structure guides the airflow to ensure that the air outlet of the fan 3 can flow smoothly to the first air passage 21, the second air outlet 14, or the third air outlet 15, reliably separating the inlet and outlet of the fan 3, preventing the airflow driven by the fan 3 from circulating within the fan cavity 12, thereby ensuring the reliable operation of the ducted air conditioner.

[0055] To further improve the air delivery effect of the ducted air conditioner, there are two fans 3 arranged side by side in the fan cavity 12. The second air outlet 22 and the fourth air outlet 16 are both corresponding to the fans 3. That is, each fan 3 corresponds to a second air outlet 22 and a fourth air outlet 16, ensuring the working reliability of each fan 3. The air outlets of the two fans 3 can converge and flow in the fan cavity 12, or converge and flow at the first air outlet 21, the second air outlet 14 or the third air outlet 15 under the guidance of the flow guiding structure, thereby ensuring the working reliability of the ducted air conditioner.

[0056] like Figure 1 As shown, the first air inlet 21, the second air inlet 14 and the third air inlet 15 are all located between the two fans 3, that is, the two fans 3 are respectively arranged at both ends of the length direction of the fan cavity 12. In this way, the two fourth air inlets 16 and the two second air inlets 22 can be arranged at intervals to avoid mutual interference of the air intake of the two fans 3 and ensure the working reliability of the duct machine.

[0057] The housing 1 includes a first side and a second side opposite to each other, and a third side located between the first side and the second side. The first air vent 13 is located on the first side, the second air vent 14 is located on the second side, and the third air vent 15 is located on the third side. That is, the first side and the second side are opposite sides of the ducted air conditioner. The ducted air conditioner can be arranged in the middle of the room and deliver air to both sides. At the same time, the third side can be arranged in other directions to further increase the air delivery direction of the ducted air conditioner.

[0058] Preferably, the third side is located at the bottom of the housing 1, and the air outlet 15 is vertically downward. When the ducted air conditioner is heating, the third air outlet 15 can be selected to discharge air, allowing hot air to flow quickly to the bottom of the room, thus achieving rapid heating.

[0059] The control logic of the ducted air conditioner is as follows: the ducted air conditioner acquires the target mode and the target air level; determines the on / off state of the first air inlet 21, the second air inlet 22, the second air outlet 14, the third air outlet 15, and the fourth air outlet 16 according to the target mode; controls the number of steps of each stepper motor according to the on / off state of the first air inlet 21, the second air inlet 22, the second air outlet 14, the third air outlet 15, and the fourth air outlet 16, thereby driving each guide vane 41 to swing to a certain angle, so that the on / off state of the first air inlet 21, the second air inlet 22, the second air outlet 14, the third air outlet 15, and the fourth air outlet 16 reaches the expected state; the ducted air conditioner determines the speed of the fan 3 according to the target air level; controls the fan 3 to operate according to the determined speed, so that the ducted air conditioner operates under the target air level.

[0060] An air conditioning unit, including the aforementioned ducted unit.

[0061] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
