[0039] In traditional buildings, the living room and the dining room are two independent but interconnected spaces, and both the dining room and the living room have heat exchange and air supply requirements. The duct machine in the prior art can only blow air in a single direction. When installing the duct machine, the user can only place the duct machine in the dining room and supply air to the living room. In this case, the duct machine is far away from the living room, and the air supply effect in the living room is poor. Alternatively, the duct machine is placed in the living room and supplies air to the dining room. In this case, the duct machine is far away from the dining room, and the air supply effect in the dining room is poor. Ultimately, both will cause the problem of poor air supply effect of the duct machine. At the same time, due to the aforementioned position limitation, the arrangement of the duct machine will also limit the decoration style of the building, affecting the user experience. To this end, the present application provides a method such as Figures 1 to 6The duct dryer shown comprises: a shell 1; a partition 2, wherein the partition 2 is arranged in the shell 1, and the partition 2 divides the interior of the shell 1 into a heat exchange chamber 11 and a fan chamber 12, and an air outlet is provided on the partition 2, and the heat exchange chamber 11 can be connected 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 the first side of the shell 1, the second air outlet 14 can discharge air to the second side of the shell 1, the third air outlet 15 can discharge air to the third side of the shell 1, and the fourth air outlet 16 can inlet air to the fan chamber 12. By arranging the first air outlet 13, the second air outlet 14 and the third air outlet 15 with different air outlet directions on the shell 1, the duct machine can realize air supply in three directions. When the present application is applied 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 provided to further increase the air supply direction of the duct machine, so that the duct machine can realize air supply to different areas. In particular, the third air outlet 15 is provided on the lower surface of the duct machine. When the duct machine is heating, heating air supply can be carried out through the third air outlet 15, so that the hot air can be quickly blown to the bottom surface, thereby improving the heating effect of the duct machine. In addition, the fourth air outlet 16 is provided so that the duct machine does not use the second air outlet 14 and the third air outlet 15 for air intake when the first air outlet 13 is discharging air, so that the fan in the duct machine does not need to be reversed or moved, thereby reducing the air outlet reversing time of the duct machine and the noise that may be caused by the movement of the fan during the air outlet reversing, further improving the air supply effect of the duct machine and the user experience.

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

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

[0042] When the duct 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 is supplying air, in order to ensure that the airflow passes through the heat exchanger reliably, the gas needs to enter the heat exchange chamber 11 through the first air outlet 13, and then pass through the heat exchanger in the heat exchange chamber 11 for heat exchange, and then pass through the partition 2 into the fan chamber 12, and be discharged through the second air outlet 14 under the action of the fan in the fan chamber 12. At this time, the third air outlet 15 and the fourth air outlet 16 are kept closed, limiting the gas in the fan chamber 12 to be discharged only through the second air outlet 14, thereby achieving the effect of the duct air conditioner supplying air to the second side;

[0043] When the duct 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 is supplying air, in order to ensure that the airflow passes through the heat exchanger reliably, the gas needs to enter the heat exchange chamber 11 from the first air outlet 13, and then pass through the heat exchanger in the heat exchange chamber 11 after heat exchange, and then pass through the partition 2 into the fan chamber 12, and be discharged through the third air outlet 15 under the action of the fan in the fan chamber 12. At this time, the second air outlet 14 and the fourth air outlet 16 are kept closed, and the gas in the fan chamber 12 can only be discharged through the third air outlet 15, thereby achieving the effect of the duct air conditioner supplying air to the third side.

[0044] The duct machine also includes a fan 3, which is arranged in the fan cavity 12, and the air outlet includes a first air outlet 21 and a second air outlet 22. By setting the fourth air outlet 16 and the second air outlet 22, the fan 3 can switch between the connection with the outside of the shell 1 and the connection with the heat exchange cavity 11 without reversing and moving. It only needs to control the opening and closing states of the fourth air outlet 16 and the second air outlet 22, which reduces the air outlet reversing time of the duct machine and the noise caused by the need to move the fan 3 to change the air flow direction, thereby improving the air supply effect and user experience of the duct machine, wherein the working state of the first air outlet 21 and the working state of the second air outlet 22 are opposite, so that only one-way flow of gas can be carried out between the heat exchange cavity 11 and the fan cavity 12;

[0045] When the duct air conditioner is in the first side air outlet mode, the inlet of the fan 3 is connected with the fourth air outlet 16, the outlet of the fan 3 is connected with the heat exchange chamber 11 through the first air outlet 21, and the second air outlet 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 outlet 21, and because the second air outlet 22 is in a closed state, the fan 3 cannot obtain gas from the heat exchange chamber 11 through the second air outlet 22, thereby ensuring the normal operation of the duct air conditioner. At this time, the gas outside the shell 1 (indoors) passes through the fourth air outlet 16, the inlet of the fan 3, the outlet of the fan 3, the first air outlet 21, the heat exchange chamber 11 and the first air outlet 13 in turn and flows back to the room, completing the heat exchange process of the first side air supply;

[0046] When the duct 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, the outlet of the fan 3 is connected to the second air outlet 14, and 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, and the fan 3 cannot obtain gas from the outside of the shell 1 through the first air outlet 21, thereby ensuring the normal operation of the duct air conditioner. At this time, the gas outside the shell 1 (indoors) flows back to 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 in turn, completing the heat exchange process of the second side air supply;

[0047] When the duct machine 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, the outlet of the fan 3 is connected to the third air outlet 15, and 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 at this time, and the fan 3 cannot obtain gas from outside the shell 1 through the first air outlet 21, thereby ensuring the normal operation of the duct machine. At this time, the gas outside the shell 1 (indoors) passes 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 turn and flows back to the room, 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. At this time, 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 perform normal airflow drive according to the working requirements of the duct machine, thereby ensuring the working reliability of the duct machine. 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 connectivity between the first inlet and the second air outlet, and a guide pipe can be set between the first inlet and the second air outlet 22 for diversion, and the projection of the second inlet on the shell 1 is within the range of the fourth air outlet 16, ensuring reliable connectivity between the second inlet and the fourth air outlet 16, and a guide pipe can be set between the second inlet and the fourth air outlet 16 for diversion.

[0049] Among them, the fan 3 is a centrifugal fan, and the two ends of the volute of the centrifugal fan respectively form the first inlet and the second inlet, 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, and the shell 1 has a side surface that is parallel to the partition 2 and constitutes a part of the side wall of the fan cavity 12. The fourth air outlet 16 can be arranged on this side surface, so as to facilitate the arrangement of the fan 3, the second air outlet 22 and the fourth air outlet 16.

[0050] The air duct machine also includes an air valve assembly 4, and the first air outlet 21, the second air outlet 22, the second air outlet 14, the third air outlet 15 and the fourth air outlet 16 are all provided with the air valve assembly 4. The state switching of the air valve assembly 4 is utilized to realize the state switching of the first air outlet 21, the second air outlet 22, the second air outlet 14, the third air outlet 15 and the fourth air outlet 16, thereby realizing reliable control of the air inlet and outlet directions of the air duct machine.

[0051] As an embodiment, the air valve assembly 4 includes a driving mechanism 42 and a plurality of air guide blades 41, all of which are arranged in parallel, and all of which are connected to the driving mechanism 42, and the driving mechanism 42 can drive all of the air guide blades 41 to move to adjust the spacing between two adjacent air guide blades 41, when the air valve assembly 4 is switched to a closed state, all of the air guide blades 41 are laid flat in the same plane or adjacent air guide blades 41 overlap and seal each other, thereby closing the opening where the air valve assembly 4 is located, and when the air valve assembly 4 is switched to an open state, the spacing between the air guide blades 41 increases to allow gas to flow through the spacing, thereby opening the opening where the air valve assembly 4 is located. Among them, the driving mechanism 42 is a stepper motor, and the stepper motor drives the air guide blades 41 to open and close with low noise, and the centrifugal fan does not need to stop running during the process of turning the air outlet direction of the air duct machine, avoiding the noise caused by the fan 3 needing to move to achieve the change of airflow direction, and eliminating the waiting time of the fan 3 stopping during the turning process. The wind guide blades 41 open and close to change the wind direction, solving the problem of long wind direction change time and high noise, and realizing senseless steering

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

[0053] Preferably, when the air valve assembly 4 switches from a closed state to an open state, the rotation angle of the air guide blade 41 is 90°, at which time the air guide blade 41 has the weakest ability to block the airflow, thereby avoiding the air valve assembly 4 from blocking the airflow.

[0054] The duct machine also includes a guide structure, which is arranged in the fan cavity 12, and the guide inlet of the guide structure is connected to the outlet of the fan 3. The guide structure has three guide outlets, and one of the guide outlets is connected to the first air outlet 21, one of the guide outlets is connected to the second air outlet 14, and one of the guide outlets is connected to the third air outlet 15. The guide structure is used to guide the airflow to ensure that the air outlet of the fan 3 can flow smoothly to the first air outlet 21, the second air outlet 14 or the third air outlet 15, and the inlet of the fan 3 and the outlet of the fan 3 are reliably separated to avoid the fan 3 driving the airflow to circulate in the fan cavity 12, thereby ensuring the reliable operation of the duct machine.

[0055] In order to further improve the air supply effect of the duct air conditioner, the number of the fans 3 is two, and the two fans 3 are arranged in parallel in the fan cavity 12, and the second air outlet 22 and the fourth air outlet 16 are arranged corresponding to the fans 3, that is, each fan 3 corresponds to a second air outlet 22 and a fourth air outlet 16, thereby ensuring the working reliability of each fan 3, and 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 guiding effect of the guide structure, thereby ensuring the working reliability of the duct air conditioner.

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

[0057] The shell 1 includes a first side surface and a second side surface that are opposite to each other, and a third side surface located between the first side surface and the second side surface. The first air outlet 13 is located on the first side surface, the second air outlet 14 is located on the second side surface, and the third air outlet 15 is located on the third side surface. That is, the first side and the second side are two opposite sides of the air duct machine. The air duct machine can be arranged in the middle of the room and supply air to both sides. At the same time, the third side surface can be arranged in other directions to further increase the air supply direction of the air duct machine.

[0058] Preferably, the third side is located at the bottom of the housing 1, and the outlet direction of the third air outlet 15 is vertically downward. When the duct unit is heating, the third air outlet 15 can be selected to discharge air so that the hot air quickly flows to the bottom of the room, thereby achieving the purpose of rapid heating.

[0059] The control logic of the duct air conditioner is as follows: the duct air conditioner obtains the target mode and the target wind speed; determines the switch status of the first air outlet 21, the second air outlet 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 switch status of the first air outlet 21, the second air outlet 22, the second air outlet 14, the third air outlet 15 and the fourth air outlet 16, thereby driving each air guide blade 41 to swing to a certain angle, so that the switch status of the first air outlet 21, the second air outlet 22, the second air outlet 14, the third air outlet 15 and the fourth air outlet 16 reaches the expected state; the duct air conditioner determines the rotation speed of the fan 3 according to the target wind speed; controls the operation of the fan 3 according to the determined rotation speed, so that the duct air conditioner runs at the target wind speed.

[0060] An air conditioning unit comprises the above-mentioned duct unit.

[0061] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
