[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, unless otherwise specified (e.g., "or additionally" or "or in alternatives"), the term "or" as used herein refers to a non-exclusive "or" (i.e., "and / or"). Furthermore, the various embodiments described herein are not necessarily mutually exclusive, as some embodiments can be combined with one or more other embodiments to form new embodiments.

[0041] like Figure 1 and Figure 2 As shown, the air outlets 11 of the indoor unit 1 of the air conditioner are four discontinuous outlets. Viewed from above, their air outlet coverage area is as follows: Figure 3 As shown, 360° airflow cannot be achieved; the airflow coverage of the indoor unit, viewed from the side, is as follows. Figure 4 As shown, the airflow cannot reach the space below the indoor unit 1.

[0042] Based on this, such as Figure 5 As shown, this application proposes an indoor unit 2 for an air conditioner, which includes a heat exchange component and an air outlet component. An air outlet gap 24 is formed between the air outlet component and the heat exchange component, which is provided corresponding to the air outlet 212 of the heat exchange component. In this way, the air outlet gap 24 in the indoor unit 2 can become the air outlet of the indoor unit 2, increasing the air outlet coverage of the indoor unit 2. Moreover, the air outlet component is configured to be close to or far from the air outlet 212, thereby adjusting the size of the air outlet gap 24 and thus adjusting the air volume of the air outlet gap 24. That is, this application can improve the air outlet coverage of the indoor unit 2 while adjusting the air volume.

[0043] like Figure 5 As shown, Figure 5 This is a schematic diagram of one embodiment of the indoor unit 2 of this application. The indoor unit 2 of this embodiment includes a heat exchange assembly and an air outlet assembly.

[0044] The heat exchange component has an air inlet 211 and an air outlet 212.

[0045] The heat exchange component includes a housing 21, which may have an air inlet 211 and an air outlet 212.

[0046] Optionally, air inlets 211 and air outlets 212 can be provided on different sides of the housing 21. For example, an air outlet 212 can be provided on the bottom wall of the housing 21, and an air inlet 211 can be provided on the side wall of the housing 21. In other embodiments, air inlets 211 and air outlets 212 can also be provided on the same side of the housing 21, for example, air inlets 211 and air outlets 212 can be provided on the bottom wall of the housing 21.

[0047] The heat exchange assembly may also include an air guide plate 23, which can be disposed on the outer periphery of the air outlet 212. Specifically, the air guide plate 23 can be disposed between the air outlet 212 and the air inlet 211 to separate the air outlet 212 and the air inlet 211, so as to prevent the airflow discharged from the air outlet 212 from quickly returning to the air inlet 211, thereby improving the operating efficiency of the indoor unit 2. Furthermore, the air guide plate 23 can be connected to the housing 21 to fix the air guide plate 23 and improve the separation effect of the air guide plate 23.

[0048] In addition, the heat exchange assembly may also include a fan 22 and a heat exchanger (not shown), so that indoor airflow can enter the housing 21 through the air inlet 211, pass through the heat exchanger, then flow through the fan 22, and be discharged from the air outlet 212.

[0049] The fan 22 can be an axial flow fan 22 or a mixed flow fan 22, which can cause the airflow to be discharged from the air outlet 212 along the axial direction of the fan 22. In other embodiments, the fan 22 can also be a centrifugal fan 22.

[0050] The air outlet component can be set corresponding to the air outlet 212, and the projection of the air outlet 212 along the air outlet direction falls on the air outlet component. An air outlet gap 24 is formed between the air outlet component and the heat exchange component, so that the airflow from the air outlet 212 can flow out through the air outlet gap 24 to increase the air outlet coverage of the indoor unit 2.

[0051] In this application, the air outlet gap 24 can be an annular air outlet 212, so as to achieve horizontal 360° air supply through the air outlet gap 24. Of course, in other embodiments, such as Figure 6 As shown, multiple discontinuous air outlets 212 are provided in the air outlet gap 24.

[0052] Combination Figure 5 and Figure 7It is understood that when the air outlet channel formed by the air outlet gap 24 is open, and the heat exchange component discharges the airflow along the axial direction of the heat exchange component, at least a portion of the airflow discharged from the heat exchange component changes direction upon contact with the air outlet component and is discharged along the air outlet gap 24 formed by the air outlet component and the heat exchange component, causing the direction of the airflow discharged from the air outlet gap 24 to intersect with the axial direction (X-X' direction) of the heat exchange component. The angle between the direction of the airflow discharged from the air outlet gap 24 and the axial direction of the heat exchange component is related to the shape of the surface of the air outlet component facing the heat exchange component and / or the angle between the outer edge of the surface of the air outlet component facing the heat exchange component and the axial direction of the heat exchange component. For example... Figure 4 As shown, the angle between the outer edge of the surface of the air outlet assembly facing the heat exchange assembly and the axial direction of the heat exchange assembly is approximately 80°, and the angle between the direction of the air outlet airflow discharged from the air outlet gap 24 and the axial direction of the heat exchange assembly is also approximately 80°.

[0053] The angle between the outer perimeter of the surface of the air outlet component facing the heat exchange component and the axial direction of the heat exchange component can be set to 45°-80°, for example, 50°, 60°, 70° or 75°. This allows the angle between the outer perimeter of the surface of the air outlet component near the heat exchange component and the horizontal plane to be 10-45° when the indoor unit 2 is installed in the user's home. In this way, the airflow discharged from the air outlet gap 24 will not blow directly on people, and can quickly mix with the indoor air, thereby improving the working efficiency of the indoor unit 2.

[0054] The air outlet assembly may include an air outlet shroud 25. The air outlet shroud 25 covers the air outlet 212, that is, the projection of the air outlet 212 along the air outlet direction falls on the air outlet shroud 25, so that an air outlet gap 24 can be formed between the air outlet shroud 25 and the heat exchange assembly. Further, the air outlet shroud 25 may form an air outlet gap 24 with the air guide plate 23 in the heat exchange assembly.

[0055] The angle between the outer periphery of the air outlet hood 25 and the axial direction of the heat exchange component can be 45°-80°, for example, 50°, 60°, 70° or 75°. When the indoor unit 2 is installed in the user's home, the angle between the outer periphery of the surface of the air outlet hood 25 near the heat exchange component and the horizontal plane can be 10-45°. In this way, the airflow discharged from the air outlet gap 24 will not blow directly on people, and can quickly mix with the indoor air to improve the working efficiency of the indoor unit 2.

[0056] Specifically, the air outlet hood 25 may include a top wall and a peripheral side wall disposed around the top wall. The peripheral side wall is disposed on the side of the top wall away from the heat exchange component. The angle between the peripheral side wall and the axial direction of the heat exchange component is 45°-80°, so that the angle between the periphery of the air outlet hood 25 and the axial direction of the heat exchange component is 45°-80°.

[0057] The shape of the air vent 25 is not limited; for example, it can be cylindrical or hollow frustum.

[0058] In addition, the air outlet assembly can be configured to be close to or far from the air outlet 212 to adjust the size of the air outlet gap 24, thereby adjusting the air volume of the air outlet gap.

[0059] The position of the air outlet component can be adjusted by the drive component, so that the air outlet component is closer to or farther away from the air outlet 212.

[0060] The drive assembly may include a telescopic motor (not shown) connected to the air outlet assembly. The output shaft of the telescopic motor can extend or retract, thereby controlling the air outlet assembly to move closer to or away from the air outlet 212. In another embodiment, the drive assembly may include a rotary motor and a second steering mechanism (which may be a screw and nut assembly or a crank and connecting rod assembly). The second steering mechanism is connected to the output shaft of the rotary motor and the air outlet assembly. Specifically, the second steering mechanism may be connected to the air outlet assembly and can convert the rotational force of the rotary motor into a telescopic force to control the air outlet assembly to move closer to or away from the air outlet 212. In yet another embodiment, the drive assembly may include a first electromagnet disposed on the heat exchange assembly and a second electromagnet disposed on the air outlet assembly. By changing the polarity of the first or second electromagnet and utilizing the principle of like poles attracting and unlike poles repelling, the air outlet assembly can be moved closer to or away from the heat exchange assembly.

[0061] The air outlet assembly may also have adjustable air holes 26, so that the indoor unit 2 of this application can have two air outlet paths: the air outlet gap 24 and the adjustable air holes 26. The direction of the airflow discharged from the adjustable air holes 26 is different from the direction of the airflow discharged from the air outlet gap 24, which can increase the coverage of the air outlet of the indoor unit 2.

[0062] Specifically, adjustable air vents 26 can be provided on the air hood 25.

[0063] like Figure 8 As shown, the air outlet hood 25 can be provided with multiple adjustable air holes 26. The number of adjustable air holes 26 on the air outlet hood 25 is not limited and can be set according to the actual situation.

[0064] The shape and / or size of the plurality of adjustable air holes 26 on the air outlet shroud 25 may be different. In other embodiments, the shape and / or size of the plurality of adjustable air holes 26 on the air outlet shroud 25 may also be the same. For example, the adjustable air holes 26 on the air outlet shroud 25 may all be circular holes.

[0065] Combination Figure 5 and Figure 9It is known that when the heat exchange component discharges the airflow along the axial direction of the heat exchange component, since the projection of the air outlet 212 along the air outlet direction falls on the air outlet component, when the adjustable air hole 26 on the air outlet component is open, at least a portion of the adjustable air hole 26 of the air outlet component can discharge the airflow flowing along the axial direction (X-X' direction) of the heat exchange component.

[0066] Additionally, the air outlet assembly may include an air valve to adjust the size of the adjustable orifice.

[0067] Based on the inventor's research, when adjusting the size of the adjustable air hole 26 through the air valve, the air valve needs to be opened at a certain angle. During this process, the air valve is subjected to a large resistance from the airflow, making adjustment difficult. In addition, it increases the pressure pulsation and noise. Furthermore, the air valve is not circumferentially uniform, which will lead to uneven airflow from the indoor unit 2.

[0068] Based on this, this application further improves the air outlet assembly. Specifically, the air valve can be replaced with a perforated plate 27, and the perforated plate 27 can be placed over the adjustable air hole 26. The size of the adjustable air hole 26 can be adjusted by rotating the perforated plate 27 relative to the air outlet cover 25. Compared with the air valve, the adjustment of the perforated plate 27 will not be subject to greater resistance, making the adjustment easier. Moreover, it will not increase the pressure pulsation, reduce the noise of the indoor unit 2, and improve the air outlet uniformity of the indoor unit 2.

[0069] The perforated plate 27 and the air outlet cover 25 can be matched in shape. The perforated plate 27 includes perforated areas and non-perforated areas.

[0070] When the air outlet hood 25 has adjustable air holes 26 only on its bottom wall, the perforated plate 27 can be rotated relative to the air outlet hood 25 to switch the air outlet assembly to the first state. At this time, the non-perforated area on the perforated plate 27 will cover most or all of the adjustable air holes 26 on the air outlet hood 25, that is, the adjustable air holes 26 on the air outlet assembly are adjusted to the minimum. Alternatively, the perforated plate 27 can be rotated relative to the air outlet hood 25 to switch the air outlet assembly to the second state. At this time, the perforated area on the perforated plate 27 is opposite to most or all of the adjustable air holes 26 on the air outlet hood 25, so that most or all of the adjustable air holes 26 on the air outlet hood 25 are opened. That is, when the air outlet assembly is in the second state, the adjustable air holes 26 on the air outlet assembly are adjusted to the maximum. In other embodiments, adjustable air holes 26 are provided on both the sidewall and bottom wall of the air outlet hood 25; the perforated plate 27 can be rotated relative to the air outlet hood 25 to switch the air outlet assembly to a third state. At this time, the non-perforated area of ​​the bottom wall of the perforated plate 27 will cover most or all of the adjustable air holes 26 on the bottom wall of the air outlet hood 25, and the perforated area of ​​the sidewall of the perforated plate 27 is opposite to most or all of the adjustable air holes 26 on the sidewall of the air outlet hood 25, so that most or all of the adjustable air holes 26 on the sidewall of the air outlet hood 25 are opened and the air holes 26 on the bottom wall of the air outlet hood 25 are opened. Most or all of the adjustable air holes 26 are closed; the perforated plate 27 can also be rotated relative to the air outlet hood 25 to switch the air outlet assembly to the fourth state. At this time, the perforated area of ​​the bottom wall of the perforated plate 27 is opposite to most or all of the adjustable air holes 26 on the bottom wall of the air outlet hood 25, and the non-perforated area of ​​the side wall of the perforated plate 27 covers most or all of the adjustable air holes 26 on the side wall of the air outlet hood 25, so that most or all of the adjustable air holes 26 on the side wall of the air outlet hood 25 are closed and most or all of the adjustable air holes 26 on the bottom wall of the air outlet hood 25 are opened.

[0071] Furthermore, this application can rotate the perforated plate 27 relative to the air outlet hood 25 by driving the component, and move the air outlet assembly composed of the perforated plate 27 and the air outlet hood 25 away from or close to the heat exchange assembly.

[0072] In one embodiment, the drive assembly may include a telescopic motor and a first steering mechanism (which may be a crank-connecting rod assembly). The telescopic motor may be directly connected to one of the air outlet shroud 25 and the perforated plate 27 to control the air outlet assembly composed of the perforated plate 27 and the air outlet shroud 25 to move away from or closer to the heat exchange assembly. The telescopic motor is also connected to the first steering mechanism, which may be connected to the other of the air outlet shroud 25 and the perforated plate 27. The first steering mechanism can convert the telescopic force of the telescopic motor into rotational force to control the perforated plate 27 to rotate relative to the air outlet shroud 25.

[0073] In another embodiment, the drive assembly may include a rotary motor and a second steering mechanism. The output end of the rotary motor may be directly connected to one of the air outlet hood 25 and the perforated plate 27 to control the perforated plate 27 to rotate relative to the air outlet hood 25. The rotary motor may also be connected to the other of the air outlet hood 25 and the perforated plate 27 through the second steering mechanism. The second steering mechanism may convert the rotational force of the rotary motor into a telescopic force to control the air outlet assembly to move away from or closer to the heat exchange assembly.

[0074] In another embodiment, the driving component may include a first electromagnet disposed on the heat exchange component, a second electromagnet disposed on the air outlet shroud 25, and a third electromagnet disposed on the perforated plate 27. By changing the polarity of the first, second, or third electromagnet and utilizing the principle of like poles attracting and unlike poles repelling, the air outlet component can be moved away from or closer to the heat exchange component. Furthermore, by changing the polarity of the second or third electromagnet and utilizing the principle of like poles attracting and unlike poles repelling, the perforated plate 27 can be rotated relative to the air outlet shroud 25.

[0075] In yet another embodiment, such as Figure 10 As shown, the drive assembly may include at least one first motor 28 and a second motor 29. The first motor 28 is connected to one of the air outlet hood 25 and the perforated plate 27 to drive one of the air outlet hood 25 and the perforated plate 27 to move up and down, thereby also driving the other of the air outlet hood 25 and the perforated plate 27 connected to one of the air outlet hood 25 and the perforated plate 27 to move up and down, that is, driving the air outlet assembly to move up and down. The second motor 29 is connected to the other of the air outlet hood 25 and the perforated plate 27 through a connecting rod to drive the other of the air outlet hood 25 and the perforated plate 27 to rotate. The connecting rod connected to the second motor 29 may be a telescopic rod so that when the first motor 28 extends or retracts, the other of the air outlet hood 25 and the perforated plate 27 can also move up and down along with the one of the air outlet hood 25 and the perforated plate 27.

[0076] Additionally, by adjusting the size of the adjustable air vent 26 and the air outlet gap 24, most of the air from the indoor unit 2 can be discharged through either the adjustable air vent 26 or the air outlet gap 24. For example, as Figure 9 As shown, the air outlet assembly can be positioned closer to the air outlet 212 to reduce the air outlet gap 24 (or even close the air outlet gap 24), and the adjustable air vent 26 on the air outlet assembly can be enlarged so that most of the air from the indoor unit 2 is exhausted through the adjustable air vent 26. For example, as... Figure 7 As shown, the air outlet assembly can be moved away from the air outlet 212 to increase the air outlet gap 24, and the adjustable air hole 26 on the air outlet assembly can be reduced (or even closed), so that most of the air from the indoor unit 2 is discharged through the air outlet gap 24.

[0077] When the indoor unit 2 is in operation, the axial direction (X-X' direction) of the heat exchange component is approximately perpendicular to the ground plane, and the heat exchange component is located on the side of the air outlet component away from the ground plane; thus, when the adjustable air holes 26 on the air outlet component are open, at least a portion of the adjustable air holes 26 of the air outlet component will discharge airflow that blows directly to the ground plane; when the air outlet channel formed by the air outlet gap 24 is open, the indoor unit 2 will discharge airflow to the surroundings of the indoor unit 2 through the air outlet gap 24.

[0078] To improve the comfort of air conditioning use, if the heat exchanger's outlet air is hot air, the air outlet assembly can be positioned closer to the outlet 212 to reduce the outlet gap 24 (or even close the outlet gap 24), and the adjustable air vents 26 on the outlet assembly can be enlarged. This ensures that most of the air from the indoor unit 2 blows directly to the ground through the adjustable air vents 26, and utilizes the natural upward movement of hot air to achieve better airflow circulation in the indoor space. This results in 180° full coverage of hot air on the vertical plane, preventing significant temperature differences below and around the indoor unit 2, ensuring uniform indoor temperature distribution, and improving the comfort of using the air conditioning in heating mode. Furthermore, the airflow velocity from the indoor unit 2 decreases to approximately 0.3 m / s before reaching the human body, eliminating any discomfort from the draft. Figure 11 The simulation analysis shown reveals that the temperature stratification phenomenon of the indoor unit 2 in this application is reduced during heating. If the air outlet of the heat exchange component is cold air, the method of "moving the air outlet component away from the air outlet 212 to increase the air outlet gap 24 and reducing the size of the adjustable air hole 26 on the air outlet component" can be adopted to make the air outlet of the indoor unit 2 blow horizontally to all sides of the air conditioner, and make full use of the natural sinking of cold air, so that the original hot air in the room quickly flows back to the top and then quickly enters the indoor unit through the air inlet, thereby achieving better airflow circulation in the indoor space more quickly, achieving uniform temperature at different heights in the room, improving the comfort of using the air conditioning cooling mode, and through methods such as Figure 12 The simulation analysis shown indicates that the temperature difference within the horizontal plane of the indoor unit 2 in this application can decrease by about 2° when it is cooling.

[0079] In addition, the movement of the air outlet assembly moving away / approaching and the adjustment of the adjustable air vent 26 can be performed simultaneously, so that the air volume of the indoor unit 2 in the horizontal and vertical directions changes in real time. This change can be altered by the motion function of the two actions to simulate winds with specific characteristics, such as valley winds / sea winds. This is a method to simulate specific wind fields without adjusting the speed of the fan 22, and it can ensure the cooling or heating capacity.

[0080] Please see Figure 13 , Figure 13 This is a schematic diagram of the structure of an embodiment of the air conditioner 3 of this application. The air conditioner 3 may include the indoor unit 22 described above.
