[0042] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] Please also read Figures 1 to 9 In the first aspect, the embodiment of the present application provides a duct air conditioner, including a housing 10, a fan assembly 20, a heat exchange assembly 30 and a valve unit 40. The housing 10 has a first cavity 10a and a second cavity 10b arranged along a first direction, an air inlet 10c and a fresh air outlet 10d are provided on the cavity wall of the first cavity 10a, and an air outlet 10e is provided on the cavity wall of the second cavity 10b; the fan assembly 20 is arranged in the first cavity 10a, and the heat exchange assembly 30 is arranged in the second cavity 10b, and the air flow in the first cavity 10a can pass through the heat exchange assembly 30 and the air outlet 10e in sequence; the valve unit 40 can at least be used to open or close the fresh air outlet 10d, and can at least be used to open or close the air inlet 10c.

[0044] In a second aspect, an embodiment of the present application provides an air conditioner, comprising an outdoor unit and a duct unit according to any embodiment of the present application. The duct unit is the indoor unit of the air conditioner.

[0045] The specific direction of the first direction is not limited. For example, the first direction is Figures 1 to 3 The direction shown by L1.

[0046] The air inlet 10c and the air outlet 10e are both connected to the room. Specifically, when the room includes multiple rooms, each room can be provided with a return air branch pipe and an outlet air branch pipe, and each return air branch pipe can be connected to the air inlet 10c; or, each can be connected to a return air main pipe, and the return air main pipe is connected to the air inlet 10c. Each outlet air branch pipe can also be connected to the air outlet 10e; or, each can be connected to an outlet air main pipe, and the outlet air main pipe is connected to the air outlet 10e.

[0047] The number of fresh air vents 10d is not limited. For example, fresh air vents 10d are provided on the cavity walls on both sides of the first cavity 10a along the second direction. By providing multiple fresh air vents 10d, it is helpful to increase the amount of outdoor fresh air introduced, thereby improving the efficiency of introducing outdoor fresh air.

[0048] The second direction intersects with the first direction. Specifically, it can be orthogonal. The specific direction of the second direction is not limited. Exemplarily, the second direction is Figure 1 The direction shown by L2.

[0049] The housing 10 forms the appearance of the duct machine, and its specific shape is not limited. Figure 2 and Figure 3 As shown, the housing 10 includes a housing body 11 and a partition wall 12. The partition wall 12 is arranged in the housing body 11 to divide the space in the housing body 11 into a first cavity 10a and a second cavity 10b. A connecting port is opened on the partition wall 12, and the first cavity 10a and the second cavity 10b are connected through the connecting port.

[0050] The fan assembly 20 is used to guide the air flow. The fan assembly 20 blows the air in the first cavity 10a to the second cavity 10b, generating negative pressure in the first cavity 10a. The air outside the duct machine can enter the first cavity 10a through the air inlet 10c or the fresh air outlet 10d, and the air in the second cavity 10b can be discharged through the air outlet 10e.

[0051] The type of the fan assembly 20 is not limited, and can be, for example, an axial flow fan, a centrifugal fan, and the like.

[0052] The air in the second cavity 10b exchanges heat with the heat exchange component 30, and the air after heat exchange is discharged through the air outlet 10e for use. It should be noted that when the air duct unit operates in cooling mode, the heat exchange component 30 is regarded as an evaporator, and when it operates in heating mode, the heat exchange component 30 is regarded as a condenser.

[0053] The fresh air inlet 10d is provided on the wall of the first cavity 10a. That is, the outdoor fresh air enters the first cavity 10a through the fresh air inlet 10d, and is discharged through the air outlet 10e after heat exchange with the heat exchange component 30 in the second cavity 10b, that is, the outdoor fresh air will not be directly introduced into the room. Therefore, in the process of introducing outdoor fresh air, the duct air conditioner is conducive to improving the problem of indoor temperature fluctuation, thereby improving the user experience.

[0054] The valve unit 40 opens the air inlet 10c, and the indoor air can enter the first cavity 10a through the air inlet 10c. The valve unit closes the air inlet 10c, and the indoor air cannot enter the first cavity 10a through the air inlet 10c. Specifically, the valve unit 40 can adjust the flow cross-sectional area of ​​the air inlet 10c, and by adjusting the flow cross-sectional area of ​​the air inlet 10c, the air volume entering the first cavity 10a through the air inlet 10c can be adjusted. It can be understood that the specific value of the flow cross-sectional area can be any value less than or equal to the area of ​​the air inlet 10c.

[0055] The valve unit 40 opens or closes the fresh air port 10d, so that the air duct unit can selectively introduce or not introduce outdoor fresh air, thereby introducing outdoor fresh air according to actual needs.

[0056] The duct machine in the embodiment of the present application has at least the following operating modes:

[0057] The first

[0058] Normal operation mode: the valve unit 40 closes the fresh air port 10d and adjusts the flow cross-sectional area of ​​the air inlet 10c to a certain value, so that the outdoor fresh air does not enter the first cavity 10a from the fresh air port 10d, and the indoor air enters the first cavity 10a from the air inlet 10c, exchanges heat with the heat exchange component 30 in the second cavity 10b, and flows out through the air outlet 10e. This operation mode can be roughly understood as the indoor air internal circulation operation mode.

[0059] The second

[0060] Fresh air operation mode: the valve unit 40 closes the air inlet 10c and opens the fresh air outlet 10d, and the outdoor fresh air enters the first cavity 10a through the fresh air outlet 10d, and the outdoor fresh air exchanges heat with the heat exchange component 30 and flows out through the air outlet 10e.

[0061] The third

[0062] Fresh air supplementation operation mode: the valve unit 40 opens the fresh air port 10d and adjusts the flow cross-sectional area of ​​the air inlet 10c to a certain value, the indoor air enters the first cavity 10a through the air inlet 10c, and the outdoor fresh air enters the first cavity 10a through the fresh air port 10d, and both the indoor air and the outdoor fresh air can exchange heat with the heat exchange component 30 and then flow out through the air outlet 10e. In this mode, the room can maintain a slight positive pressure, thereby effectively reducing the probability of outdoor dust entering the room.

[0063] In addition, in this operating mode, the valve unit 40 adjusts the relationship between the incoming air entering the first cavity 10a through the air inlet 10c and the outdoor fresh air, and cooperates with the high static pressure fan to achieve long-distance air supply.

[0064] In the related art, a duct-type air conditioner is equipped with a fresh air structure on the indoor unit side so that outdoor fresh air can be introduced according to actual needs. However, a duct-type air conditioner with such a structure needs to separately set up a fresh air structure, resulting in a relatively high cost of the air conditioner. In addition, in the process of introducing outdoor fresh air, the outdoor fresh air is directly introduced into the room through the fresh air structure, resulting in large fluctuations in indoor temperature.

[0065] In the duct air conditioner of the embodiment of the present application, a fresh air port 10d and an air inlet 10c are provided on the side wall of the first cavity 10a. When it is necessary to introduce outdoor fresh air, the valve unit 40 is controlled to open the fresh air port 10d; when it is not necessary to introduce outdoor fresh air, the valve unit 40 is controlled to close the fresh air port 10d. Therefore, the duct air conditioner can introduce outdoor fresh air according to actual needs, and the outdoor fresh air can be introduced from the fresh air port 10d through the fan assembly 20 in the first cavity 10a. The duct air conditioner does not need to set up a separate fresh air structure, which is beneficial to reduce the cost of the air conditioner. At the same time, since the fresh air inlet 10d is opened on the wall of the first cavity 10a and the air outlet 10e is opened on the wall of the second cavity 10b, the outdoor fresh air enters the first cavity 10a through the fresh air inlet 10d, exchanges heat with the heat exchange component 30 in the second cavity 10b, and then flows out through the air outlet 10e. That is, the outdoor fresh air will not be directly introduced into the room, but will be replenished into the room after the temperature is adjusted by the heat exchange component 30. Therefore, when the outdoor fresh air is introduced, it is helpful to improve the problem of indoor temperature fluctuations.

[0066] In addition, for the duct air conditioner of the embodiment of the present application, when the side with the air inlet 10c is a wall and the bottom of the duct air conditioner is a wardrobe, which makes the installation environment of the duct air conditioner extremely demanding, the fresh air outlet 10d can be disconnected from the fresh air duct, that is, the fresh air outlet 10d is directly connected to the room, thereby increasing the return air effect of the indoor air and improving the problem of unsatisfactory heat exchange of the duct air conditioner in this special installation environment. In other words, it is helpful to reduce the influence of the wall and the like on the air intake of the duct air conditioner.

[0067] See also Figures 1 to 3, Figures 7 to 9 In one embodiment, the heat exchange component 30 divides the second cavity 10b into a first space 10ba and a second space 10bb. The airflow in the first cavity 10a flows to the second space 10bb after passing through the first space 10ba. The heat exchange component 30 can selectively open or block the airflow path between the first space 10ba and the second space 10bb. An openable and closable exhaust port 10m is provided on the side wall of the first space 10ba, and an outlet port 10e is provided on the side wall of the second space 10bb.

[0068] The air conditioner further includes an exhaust duct, one end of which is connected to the exhaust port 10m, and the other end of which is connected to the outside.

[0069] In this embodiment, the duct air conditioner also has the following fourth operating mode.

[0070] Exhaust operation mode: The heat exchange component 30 blocks the air flow path between the first space 10ba and the second space 10bb, the valve unit 40 opens the exhaust port 10m, closes the fresh air port 10d, and adjusts the flow cross-sectional area of ​​the air inlet 10c to a certain value. After the fan component 20 is running, the air in the first cavity 10a is blown into the first space 10ba, and a negative pressure is generated in the first cavity 10a. The indoor air enters the first cavity 10a through the air inlet 10c, and the air in the first space 10ba cannot enter the second space 10bb, so it will be discharged to the outside through the exhaust port 10m. In this operation mode, the user can slightly open the door or window to gradually replace the indoor air.

[0071] In other words, when this operating mode is used to replace the indoor air, the indoor temperature will not change suddenly, which is beneficial to improving the user experience.

[0072] It should be noted that when the duct air conditioner operates in any one of the first, second and third operating modes mentioned above, the heat exchange component 30 needs to open the air flow path between the first space 10ba and the second space 10bb.

[0073] See also Figures 1 to 3In one embodiment, the heat exchange component 30 includes a heat exchanger 31 and a barrier 32. The heat exchanger 31 divides the second cavity 10b into a first space 10ba and a second space 10bb. The barrier 32 has a first state and a second state. In the first state, the barrier 32 covers a side of the heat exchanger 31 facing the first space 10ba and / or a side facing the second space 10bb to block the airflow path between the first space 10ba and the second space 10bb; in the second state, the barrier 32 is separated from at least a portion of the side of the heat exchange component 30 facing the first space 10ba and at least a portion of the side facing the second space 10bb to conduct the airflow path between the first space 10ba and the second space 10bb.

[0074] The type of the barrier 32 is not limited, as long as it can block the airflow. For example, the barrier 32 can be a screen.

[0075] When the first space 10ba and the second space 10bb are arranged along the first direction, the side of the heat exchanger 31 facing the first space 10ba and the side facing the second space 10bb are the opposite sides of the heat exchanger 31 along the first direction, that is, in the first state, the barrier 32 covers at least one side of the heat exchanger 31 along the first direction.

[0076] When the barrier 32 is in the first state, the air in the first space 10ba cannot pass through the heat exchange component 30, and thus the air in the first space 10ba can flow out from the exhaust port 10m; when the barrier 32 is in the second state, since the air in the first space 10ba can pass through the heat exchanger 31, after the valve unit 40 closes the exhaust port 10m, the air in the first space 10ba enters the second space 10bb after heat exchange in the heat exchanger 31, and flows out through the outlet 10e.

[0077] Through the matching structure of the blocking member 32 and the heat exchanger 31 , the heat exchange assembly 30 can selectively open or block the airflow path between the first space 10ba and the second space 10bb.

[0078] See also Figures 1 to 3 In one embodiment, one side of the barrier 32 is rotatably connected to the heat exchanger 31 or the housing 10, and the barrier 32 rotates relative to the heat exchanger 31 to switch between the first state and the second state.

[0079] like Figure 2 As shown, in the first state, the blocking member 32 forms a certain angle with the heat exchanger 31, and the air in the first space 10ba can pass through the heat exchanger 31 and enter the second space 10bb.

[0080] like Figure 3As shown, in the second state, the barrier 32 is nearly parallel to the heat exchanger 31, and the air needs to pass through the barrier 32 before passing through the heat exchanger 31. Since the barrier 32 is difficult to pass through, the air flow path between the first space 10ba and the second space 10bb is blocked.

[0081] The blocking member 32 is switched between the first state and the second state by a unilaterally rotating structure. This structure is relatively simple and easy to implement.

[0082] In some other embodiments, the barrier member 32 may also be switched between the first state and the second state in the form of telescoping or pulling.

[0083] See also Figures 7 to 9 In one embodiment, the valve unit 40 includes a first valve assembly 41, the first valve assembly 41 includes a first air valve 411 and a first driving member (not shown) drivingly connected to the first air valve 411, the first air valve 411 is arranged at the fresh air outlet 10d, and the first driving member is used to drive the first air valve 411 to move to open or close the fresh air outlet 10d.

[0084] The type of the first driving member is not limited, and can be, for example, various types of motors.

[0085] In this embodiment, the first air valve 411 can be automatically controlled, which is beneficial to improving the automation level of the duct air conditioner and providing a higher user experience.

[0086] See also Figures 7 to 9 In one embodiment, the valve unit 40 includes a second valve assembly 42, the second valve assembly 42 includes a second air valve 421 and a second driving member (not shown) drivingly connected to the second air valve 421, the second air valve 421 is arranged at the exhaust port 10m, and the second driving member is used to drive the second air valve 421 to move to open or close the exhaust port 10m.

[0087] The type of the second driving member is also not limited, and can be, for example, various types of motors.

[0088] In this embodiment, the second air valve 421 can also be automatically controlled, which is beneficial to improving the automation level of the duct air conditioner and providing a higher user experience.

[0089] See also Figures 7 to 9 In one embodiment, the first air valve 411 includes at least one first rotating door, one side of which is rotatably disposed at the fresh air outlet 10d, and the first rotating door is rotated to open or close the fresh air outlet 10d.

[0090] For example, Figure 8 and Fig. 9As shown, there may be two first revolving doors, and the structure of the two first revolving doors can be roughly understood as a double door.

[0091] The first revolving door may be covered on the outer wall of the casing 10. During the process of opening the fresh air outlet 10d, the first revolving door rotates around one side thereof in a direction away from the casing 10. Thus, no matter the fresh air outlet 10d is in an open state or a closed state, the first revolving door will not rotate to the inside of the casing 10, thereby avoiding interference with components installed inside the casing 10, and the reliability of the first air valve 411 is higher.

[0092] See also Figures 7 to 9 In one embodiment, the second air valve 421 includes at least one second rotating door, one side of which is rotatably disposed at the exhaust port 10m, and the second rotating door is rotated to open or close the exhaust port 10m.

[0093] For example, Figure 8 and Fig. 9 As shown, there may be two second revolving doors, and the structure of the two second revolving doors can be roughly understood as a double door.

[0094] The second revolving door may be covered on the outer wall of the casing 10. During the process of opening the exhaust port 10m, the second revolving door rotates around one side thereof in a direction away from the casing 10. Thus, no matter the exhaust port 10m is in an open state or a closed state, the second revolving door will not rotate to the inside of the casing 10, thereby avoiding interference with components installed inside the casing 10, and the reliability of the second air valve 421 is higher.

[0095] See also Figures 3 to 6 In one embodiment, the valve unit 40 includes a third valve assembly 43, the third valve assembly 43 includes an air inlet grille, the air inlet grille includes a plurality of baffles 431, each baffle 431 is rotatably disposed at the air inlet 10c, and each baffle 431 is rotated to adjust the flow cross-sectional area of ​​the air inlet 10c.

[0096] like Figure 5 As shown, each blocking bar 431 rotates to be parallel to the surface where the air inlet 10c is located, so that the air inlet 10c can be relatively completely blocked, so that the flow cross-sectional area of ​​the air inlet 10c is adjusted to a relatively small value.

[0097] like Figure 6 As shown, each baffle 431 rotates to be parallel to the direction of entering the first cavity 10a through the air inlet 10c. The indoor air can flow to the air inlet 10c through the gap between two adjacent baffles 431 and enter the first cavity 10a through the air inlet 10c. The flow cross-sectional area of ​​the air inlet 10c can be adjusted to a relatively large value.

[0098] In some other embodiments, the third valve assembly 43 may not use an air inlet grille, for example, a retractable screen or pull-out slats, etc., which only needs to be able to adjust the flow cross-sectional area of ​​the air inlet 10c.

[0099] See also Figures 3 to 6 In one embodiment, the third valve assembly 43 further includes a third driving member 432, and the third driving member 432 is used to drive each blocking bar 431 to rotate.

[0100] The type of the third driving member 432 is not limited, and can be, for example, various types of motors.

[0101] The third driving member 432 drives each baffle 431 to rotate, so that the flow cross-sectional area of ​​the air inlet 10c can be adjusted, thereby facilitating improving the automation level of the air duct machine.

[0102] In other embodiments, manual control or other control methods may be used to drive the baffles 431 to rotate, thereby helping to reduce the material cost and use cost of the duct machine.

[0103] See also Figures 1 to 3 In one embodiment, the air inlet 10c and the air outlet 10e are located on opposite sides of the housing 10 along a first direction, and the fresh air outlet 10d is provided on at least one side of the housing 10 along a second direction, wherein the second direction intersects with the first direction.

[0104] The second direction may be orthogonal to the first direction or may be at any angle.

[0105] The specific direction of the second direction is not limited. For example, the second direction is Figure 1 The direction shown by L2.

[0106] It is understandable that the duct air conditioner operates in the first operating mode mentioned above most of the time, that is, indoor air enters the first cavity 10a through the air inlet 10c, exchanges heat with the heat exchange component 30 in the second cavity 10b, and then flows out through the air outlet 10e.

[0107] That is to say, when operating in the first operating mode, the airflow inside the casing 10 flows roughly in one direction, which is beneficial to reduce the resistance encountered by the airflow during the flow, thereby facilitating the air volume of the duct air conditioner and improving the energy efficiency of the duct air conditioner.

[0108] See also Figure 1 , Figures 7 to 9 In one embodiment, the duct air conditioner further includes a fresh air connection pipe 50 disposed on the outer wall of the casing 10, and one end of the fresh air connection pipe 50 is connected to the fresh air outlet 10d.

[0109] It is understandable that after the ducted air conditioner is installed indoors, it is necessary to connect the outside with the fresh air outlet 10d through a fresh air duct so as to introduce fresh air from the outside. By providing a fresh air connecting pipe 50, the fresh air connecting pipe 50 is equivalent to protruding from the outer wall of the casing 10. During the installation of the fresh air duct, the fresh air duct can be sleeved on the fresh air connecting pipe 50. On the one hand, the fresh air duct does not need to extend into the casing 10 or be connected to the outer wall of the casing 10, thereby facilitating the installation of the fresh air duct; on the other hand, after the fresh air duct and the fresh air connecting pipe 50 form a sleeve structure, the sealing performance is better.

[0110] The specific structure of the fresh air connection pipe 50 is not limited. Figure 1 , Figure 8 and Fig. 9 The fresh air connecting pipe 50 includes a closing section, and the radial size of the closing section gradually decreases in the direction away from the fresh air outlet 10d, thereby facilitating the sleeve connection of the fresh air connecting pipe 50 and the fresh air pipe.

[0111] In some other embodiments, please refer to Figure 1 , Figure 8 and Fig. 9 When the exhaust port 10m is provided on the second cavity wall, the duct machine may also include an exhaust connecting pipe 60 provided on the casing 10, and one end of the exhaust connecting pipe 60 is connected to the exhaust port 10m.

[0112] The structure and function of the exhaust air connecting pipe 60 can be understood with reference to the fresh air connecting pipe 50 , and will not be described in detail in this application.
