[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0043] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the various specific processes and examples of materials provided by the present application, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0044] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0045] Figure 1 This is a schematic diagram of the use scenario of the duct machine, combined with Figure 1In the related art, the duct machine 1000 used in homes or public areas is usually installed on the ceiling in a hidden ceiling installation manner. It has a built-in centrifugal fan wheel. The cold air or hot air generated by the duct machine 1000 is driven by the centrifugal fan wheel to deliver the cold air or hot air to the use area. In the cooling mode, the density of the low-temperature airflow is large. After the cold air is blown out horizontally, it naturally settles, resulting in insufficient air supply distance. The far-end air supply range of the use area cannot be covered, affecting the cooling effect of the use area. If you want to get a longer air supply distance, you need to increase the fan speed. With the increase in the fan speed, the wind noise of the duct machine 1000 will increase; in the heating mode, the density of the high-temperature airflow is small. After the hot air is blown out horizontally, it floats on the roof and cannot fall to the ground, resulting in poor heating effect.

[0046] Based on the above technical problems, the embodiments of the present application provide an air outlet panel, an indoor unit and a duct unit to improve the cooling and heating effects of the use area to a certain extent.

Through the arrangement of the air guide member 1103, the refrigeration airflow generated in the cooling mode can be introduced into the first air guide cover 1102 through the air inlet, and the introduced refrigeration airflow can be led out through the second air outlet 1107, so that the airflow speed at the second air outlet 1107 is higher than the airflow speed at the first air outlet 1105, so that the refrigeration airflow led out by the second air outlet 1107 has a higher flow speed, so that a negative pressure area is generated at the air outlet panel 1100, and the original flow direction of the refrigeration airflow is changed, thereby increasing the air supply distance of the refrigeration airflow and improving the refrigeration effect of the use area.

[0049] Combination Figure 4 as well as Figure 5 The main body 1101 of the embodiment of the present application can be a through rectangular frame, which can usually be through in the horizontal direction when assembled, that is, the horizontal side of the main body 1101 is the air inlet side, the first air inlet 1104 is arranged on the air inlet side of the main body 1101, the other horizontal side of the main body 1101 is the air outlet side, and the first air outlet 1105 is arranged on the other horizontal side of the main body 1101.

[0050] Combination Figure 4 as well as Figure 5 In the embodiment of the present application, a plurality of air guide plates 1108 may be arranged at intervals in the body 1101, and two adjacent air guide plates 1108 form an air duct, the air inlet side of each air duct is the first air inlet 1104, and the air outlet side of each air duct is the first air outlet 1105. Part of the air flow is guided by the plurality of air ducts and discharged from the corresponding first air inlet 1104 to improve the balance of the air outlet.

[0051] In an embodiment of the present application, a plurality of air guide plates 1108 may be fixedly disposed in the main body 1101. In other implementation schemes, the air guide plates 1108 may also be rotatably mounted in the main body 1101 and may be maintained in any position. In this way, the rotation of the air guide plates 1108 may be controlled to achieve adjustable air outlet direction at the first air outlet 1105.

[0052] Figure 6 Schematic diagram of the structure of an air outlet panel in an embodiment of the present application. Figure 6A wind blocking member 1109 may be provided in the first air outlet 1105 located at the bottom, so that the air flow speed of the first air outlet 1105 located at the bottom can be reduced, so that the cooling air flow acts near the bottom of the panel under the cooling condition, thereby improving the balance of cooling.

[0053] Specifically, in the embodiment of the present application, an air blocker 1109 may be provided in the lowest one or two first air outlets 1105 , and multiple air blockers 1109 may be provided in each first air outlet 1105 . The multiple air blockers 1109 may be arranged at intervals in the corresponding first air outlet 1105 so that fresh air can be discharged through between adjacent air blockers 1109 .

[0054] In other embodiments, the wind blocking member 1109 may also be a grid-shaped wind shield, which is assembled in the first air outlet 1105 of the corresponding air duct so that fresh air can pass through the gaps in the wind shield.

[0055] Figure 7 for Figure 4 A schematic diagram of the structure of the first air guide cover and the second air guide cover, Figure 8 for Figure 7 Another structural diagram of the perspective. Figure 4 , Figure 5 , Figure 7 as well as Figure 8The first air guide cover 1102 can be roughly cylindrical with openings on both sides, and includes a first end plate 1110, a second end plate 1111, a first side plate 1112 and a second side plate 1113, wherein the first end plate 1110 and the second end plate 1111 can be roughly circular, and the two are arranged opposite to each other in the horizontal direction, the first side plate 1112 and the second side plate 1113 can be arc-shaped, and the two are arranged opposite to each other in the vertical direction, the top of the first end plate 1110 and the top of the second end plate 1111 are connected by the first side plate 1112, and the bottom of the first end plate 1110 and the bottom of the second end plate 1111 are connected by the second side plate 1113. When assembled, it encloses an air guide cavity that runs through in the horizontal direction, wherein the second air inlet 1106 is arranged on a horizontal side of the first air guide cover 1102 (the air inlet of the body 1101 side), the second air inlet 1106 is arranged above the first air inlet 1104, and the second air outlet 1107 is arranged on the other horizontal side of the first air guide cover 1102 (the air outlet side of the main body 1101), and the air guide member 1103 can be rotatably arranged in the first air guide cover 1102. Through the arrangement of the air guide member 1103, in the cooling mode, part of the cooling airflow can be introduced into the first air guide cover 1102 through the second air inlet 1106, and the introduced cooling airflow can be led out through the second air outlet 1107. Due to the rotation drive of the air guide member 1103, the airflow led out by the second air outlet 1107 can have a higher flow velocity, and a negative pressure area can be generated at the air outlet panel 1100, which changes the original flow direction of the cooling airflow, thereby increasing the air supply distance of the cooling airflow and improving the cooling effect of the use area.

[0056] Combination Figure 7 as well as Figure 8 A rotating shaft 1114 may be provided in the first air guide cover 1102, and the air guide member 1103 is assembled on the rotating shaft 1114. A first driving motor 1115 is provided in the first air guide cover 1102, and the output portion of the first driving motor 1115 is transmission-connected to the rotating shaft 1114. By controlling the rotation of the first driving motor 1115, the air guide member 1103 can be driven to rotate through the rotating shaft 1114 to lead out fresh air at a high speed.

[0057] Combination Figure 7 In the embodiment of the present application, a support seat 1116 is further provided in the first air guide cover 1102, and the first drive motor 1115 is installed in the support seat 1116. The first drive motor 1115 can be provided with two output parts, and the two output parts of the first drive motor 1115 can be respectively connected to the two rotating shafts 1114 to achieve the purpose of driving the two rotating shafts to rotate by one motor, thereby streamlining the structure and reducing the production cost.

[0058] In other embodiments, the end of the rotating shaft 1114 that is not connected to the first driving motor 1115 is rotatably connected to the end plate on the same side, which can improve the reliability of the rotation of the rotating shaft 1114.

[0059] The air guide member 1103 of the embodiment of the present application may be a centrifugal wind wheel, and may be provided with a plurality of air guide members 1103, wherein the plurality of air guide members 1103 are installed on the rotating shaft 1114 at intervals, and a driving motor is used to drive the plurality of air guide members 1103 to rotate synchronously, so as to improve the balance of the introduction of fresh air.

[0060] Furthermore, the first air guide cover 1102 can also be rotatably disposed in the body 1101, so that the air outlet angle can be adjusted by controlling the rotation of the first air guide cover 1102 to adapt to different usage conditions. For example, in the heating condition, the heating airflow direction can be changed so that the warm air reaches the ground.

[0061] Combination Figure 7 as well as Figure 8 A second drive motor 1117 is arranged between the second end plate 1111 and the main body 1101. The output shaft of the second drive motor 1117 is connected to the first end plate 1110 or the second end plate 1111. By controlling the rotation of the second drive motor 1117, the corresponding end plate can be driven to rotate, and then the first air guide cover 1102 is driven to rotate to adjust the air outlet angle of the second air outlet 1107 of the first air guide cover 1102.

[0062] In the embodiment of the present application, the air inlet size of the second air inlet 1106 is smaller than the air outlet size of the second air outlet 1107. This is because: the air inlet size of the second air inlet 1106 is set to S1, the air flow speed is V1, and the air outlet size of the second air outlet 1107 is set to S2, and the air flow speed is V2. According to the principle of conservation of mass, S1*V1=S2*V2. In the case where the air inlet size of the second air inlet 1106 is smaller than the air outlet size of the second air outlet 1107, the air outlet air flow speed of the second air outlet 1107 can be increased, that is, S2<S1, V1<S1V2, so as to further increase the flow speed of the airflow drawn out of the second air outlet 1107.

[0063] Combination Figure 4 , Figure 7 as well as Figure 8 The air outlet panel 1100 of the embodiment of the present application also includes a second air guide cover 1118, which is connected to the second air outlet 1107 of the first air guide cover 1102. The second air guide cover 1118 is provided with a third air outlet 1119 communicated with the second air outlet 1107, which can further guide the flow direction of the fresh air to further increase the air supply distance of the refrigeration airflow and improve the refrigeration effect of the use area.

[0064] Fig. 9 for Figure 7 A side view of Fig. 9 The second air guide cover 1118 of the embodiment of the present application can be square, that is, the second air outlet 1107 and the third air outlet 1119 are of similar size, and the second air guide cover 1118 only plays a guiding role.

[0065] Fig.10 This is a schematic diagram of the structure of another first air guide cover and a second air guide cover according to an embodiment of the present application, Fig.10 The second air guide cover 1118 is also in the shape of a cone whose size decreases gradually in the direction away from the air guide cover, that is, the size of the second air outlet 1107 is smaller than that of the third air outlet 1119, so that the induced air discharged from the third air outlet 1119 has a higher airflow speed.

[0066] It should be noted that, in the embodiment of the present application, the first air guide cover 1102 and the second air guide cover 1118 can be an integrally formed structure to facilitate assembly of components.

[0067] Combination Figure 3 Based on the above-mentioned air outlet panel 1100, the embodiment of the present application further provides an indoor unit, which includes a housing, and the above-mentioned air outlet panel 1100 is assembled on the air outlet side of the housing. The indoor unit with the above-mentioned air outlet panel 1100 can increase the air supply distance of the cooling airflow and improve the cooling effect of the use area.

[0068] Combination Figure 3 The indoor unit of the embodiment of the present application can be installed on the ceiling in a hidden ceiling installation manner, and it also includes an air inlet component and a heat exchange component. The air inlet component, the heat exchange component and the above-mentioned air outlet panel 1100 are sequentially assembled in the shell. This is the existing technology and will not be elaborated here.

[0069] In addition, the embodiment of the present application further provides a duct air conditioner 1000, which includes the indoor unit described above. The duct air conditioner 1000 with the indoor unit described above can increase the air supply distance of the refrigeration airflow and improve the refrigeration effect of the use area.

[0070] When the duct machine 1000 provided in the embodiment of the present application is actually used, in the cooling mode, the air inlet member introduces fresh air, and the introduced fresh air is converted into cold air after heat exchange by the heat exchange member. Part of the cold air is introduced into the air outlet panel 1100 through the first air inlet 1104, and is discharged horizontally from the first air outlet 1105 of the air outlet panel 1100, and is naturally transported to the use area that is closer. Another part of the cold air is introduced into the first air guide cover 1102 in the air outlet panel 1100 through the second air inlet 1106, and the air guide member 1103 is controlled to rotate so that the cold air is discharged from the second air outlet 1107, generating a negative pressure area at the upper end of the air outlet panel 1100, thereby changing the original flow direction of the refrigeration airflow and increasing the air supply distance of the refrigeration airflow. In this way, the air supply distance can be increased without increasing the fan speed, thereby reducing the refrigeration air supply noise and increasing the refrigeration air supply distance.

[0071] In the heating mode, the air inlet member introduces fresh air, and the introduced fresh air is converted into hot air after heat exchange through the heat exchange member. Part of the hot air is introduced into the air outlet panel 1100 through the first air inlet 1104, and is discharged horizontally from the first air outlet 1105 of the air outlet panel 1100, and is naturally transported to the usage area that is closer. Another part of the hot air is introduced into the first air guide hood 1102 in the air outlet panel 1100 through the second air inlet 1106. The first air guide hood 1102 is controlled to rotate so that the second air outlet 1107 of the first air guide hood 1102 is tilted downward, and the air guide member 1103 is controlled to rotate so that the hot air is discharged from the second air outlet 1107 to form a downward airflow static pressure, thereby changing the direction of the heating airflow and delivering the warm air to the ground, thereby improving the heating effect and comfort.
