Description

Technical Field

[0001] This application relates to the field of refrigeration technology, such as a dual-fan floor-standing air conditioner indoor unit and an air conditioner. Background Technology

[0002] Air conditioners are common appliances used to improve the indoor environment for users. Their temperature regulation capabilities and air delivery methods are all related to the user's experience when using air conditioners.

[0003] Taking a floor-standing air conditioner indoor unit as an example, currently, the casing of a floor-standing air conditioner indoor unit has a front air outlet, and a fan is installed inside the casing to deliver air forward. In order to meet users' needs for different air outlet directions, the casing of a floor-standing air conditioner indoor unit also has a front air outlet and a side air outlet, so as to deliver air forward or to the side according to the user's needs.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] For an indoor air conditioning unit with multiple air outlets, when only one air outlet is needed for air supply, such as when only the side air outlet is needed, the fan supplying air to the corresponding front air outlet needs to be turned off. As a result, the cooling or heating capacity of the heat exchanger section corresponding to the fan in the off state cannot be delivered, which reduces the overall heat exchange efficiency of the heat exchanger.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0010] In some alternative embodiments, the rotatable partition includes a first movable plate end near the heat exchanger and a second movable plate end opposite to the first movable plate end, wherein the rotatable partition includes a partition shaft, and the partition shaft is disposed at the second movable plate end.

[0011] In some alternative embodiments, a reference plane passing through the axis of the second fan and parallel to the diaphragm shaft is a first reference plane, the portion between the first reference plane and the heat exchanger is a first side portion, and the portion between the first reference plane and the front shell portion of the housing is a second side portion, wherein the diaphragm shaft is located on the second side portion.

[0012] In some optional embodiments, the vertical projection of the partition air outlet is a first projection block, and the cross-section of the second fan includes the projection fan cross-section falling into the first projection block. The total area of ​​the cross-section of the second fan is S, the area of ​​the projection fan cross-section is S1, and S1≥0.5S.

[0013] In some alternative embodiments, the first fan includes a first fan housing, the first fan housing includes a first fan side shell with a first impeller inlet, wherein the first fan side shell is parallel to the partition shaft of the rotatable partition.

[0015] In some alternative embodiments, the second fan includes a second fan housing, the distance from the bottom end of the first fan housing to the movable air duct partition is a first distance, and the distance from the top end of the second fan housing to the movable air duct partition is a second distance, wherein the first distance is greater than or equal to the second distance.

[0016] In some alternative embodiments, the indoor unit of the dual-fan floor-standing air conditioner further includes: an air guide ring assembly disposed in a first air duct between the first impeller air outlet of the first fan and the front air outlet; and a wind deflector assembly for partially blocking the air guide ring assembly to adjust the air outlet direction.

[0017] In some embodiments, the air conditioner includes a dual-fan floor-standing indoor unit as described above.

[0018] The dual-fan floor-standing air conditioner indoor unit and air conditioner provided in this disclosure embodiment can achieve the following technical effects:

[0019] The indoor unit of the air conditioner includes a casing, a first fan, a second fan, a heat exchanger, and a movable duct partition. The casing has an air inlet, a front air outlet at the top, and a side air outlet on the side. The first fan is connected to the front air outlet and is used to deliver air forward. The second fan is connected to the side air outlet and is used to deliver air to the side. The heat exchanger includes a first heat exchange section and a second heat exchange section. Air that has exchanged heat with the second heat exchange section is delivered through the second fan and exits through the side air outlet. The movable duct partition is located between the first fan and the second fan. The movable duct partition includes a rotatable partition. When the rotatable partition is closed, air that has exchanged heat with the first heat exchange section is delivered through the first fan and exits through the front air outlet.

[0020] The dual-fan floor-standing air conditioner indoor unit provided in this embodiment is equipped with a movable air duct partition, which is disposed between the first fan and the second fan. The movable air duct partition includes a rotatable partition. When the rotatable partition is in the closed state, it separates the first heat exchange section and the second heat exchange section of the heat exchanger, allowing air that has exchanged heat with the first heat exchange section to be discharged from the front air outlet via the first fan, and air that has exchanged heat with the second heat exchange section to be discharged from the side air outlet via the second fan. When the rotatable partition is in the open state, its rotation creates a partition air passage between the first heat exchange section and the second fan, allowing air that has exchanged heat with the first heat exchange section to pass through this partition air passage and be discharged from the side air outlet by the second fan.

[0021] In this way, when only the side air outlet is needed, the heat or cold generated by the first heat exchange section of the heat exchanger can be sent out from the side air outlet by the second fan through the baffle air outlet, thereby improving the heat exchange efficiency of the heat exchanger.

[0063] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0064] This disclosure provides a dual-fan floor-standing air conditioner indoor unit.

[0065] Optionally, the indoor unit of the air conditioner includes a housing 1, a first fan 21, a second fan 22, a heat exchanger 3, and a movable air duct partition 4. The housing 1 has an air inlet 101, and a front air outlet 102 is provided on the upper part of the housing 1, and a side air outlet 103 is provided on the side of the housing 1; the first fan 21 is connected to the front air outlet 102 and is used to deliver air forward; the second fan 22 is connected to the side air outlet 103 and is used to deliver air to the side; the heat exchanger 3 includes a first heat exchange section 31 and a second heat exchange section 32, and the air after heat exchange with the second heat exchange section 32 is delivered from the side air outlet 103 after passing through the second fan 22; the movable air duct partition 4 is disposed between the first fan 21 and the second fan 22.

[0066] The movable air duct partition 4 includes a rotatable partition 41. When the rotatable partition 41 is in the closed state, the air that has exchanged heat with the first heat exchange section 31 is sent out from the front air outlet 102 after passing through the first fan 21. When the rotatable partition 41 is in the open state, the air that has exchanged heat with the first heat exchange section 31 is sent out from the side air outlet 103 by the second fan 22 after passing through the partition air outlet 411 of the movable air duct partition 4.

[0067] Optionally, the housing 1 includes a front housing portion 11, a rear housing portion, and a side housing portion 12, with the front housing portion 11 and the rear housing portion disposed opposite to each other. An air inlet 101 is located in the rear housing portion, and an air inlet grille is provided at the air inlet 101. A front air outlet 102 is located on the upper part of the front housing portion 11, and a side air outlet 103 includes a first side air outlet and a second side air outlet. The side air outlet 103 can be located in the side housing portion 12 or on the side of the front housing portion 11.

[0068] Optionally, the front air outlet 102 is located above the side air outlet 103. Optionally, the front air outlet 102 can be circular, square, or other regular or irregular shapes; the side air outlet 103 is elongated.

[0069] Optionally, the first fan 21 may include a centrifugal fan, an axial fan, or a cross-flow fan, etc.; the second fan 22 may include a cross-flow fan, a centrifugal fan, or an axial fan, etc. For example, the first fan 21 is a centrifugal fan, and the second fan 22 is a cross-flow fan, with the centrifugal fan located above the cross-flow fan.

[0070] The indoor unit of the air conditioner provided in this embodiment also includes a movable air duct partition 4. The movable air duct partition 4 is disposed between the first fan 21 and the second fan 22. When only the side air outlet 103 needs to supply air, the rotatable partition 41 of the movable air duct partition 4 can be controlled to rotate to the conducting state, so that the rotatable partition 41 opens the partition air outlet 411. In this way, the heat or cold generated by the first heat exchange section 31 can be sent out by the second fan 22 from the side air outlet 103 through the partition air outlet 411.

[0071] As can be seen, when the air conditioner indoor unit provided in this embodiment only needs to supply air through the side air outlet 103, the heat or cold generated by the first heat exchange section 31 can be sent out through the second fan 22 from the side air outlet 103 when the first fan 21 is closed, which improves the heat exchange efficiency of the heat exchanger 3. At the same time, it avoids problems such as condensation caused by the inability of the first heat exchange section 31 to discharge cold in time.

[0072] When the user needs air to be supplied from both the front air outlet 102 and the side air outlet 103 at the same time, the rotatable partition 41 can be controlled to be in a closed state. At this time, the partition air outlet 411 is closed by the rotatable partition 41. The movable air duct partition 4 is the partition between the first fan 21 and the second fan 22. At this time, the air conditioning air after heat exchange in the first heat exchange section 31 is sent out from the front air outlet 102 through the first fan 21, and the air conditioning air after heat exchange in the second heat exchange section 32 is sent out from the side air outlet 103 through the second fan 22.

[0073] Optionally, the first heat exchange section 31 and the second heat exchange section 32 of the heat exchanger 3 are integrally formed, and the refrigerant pipeline between the first heat exchange section 31 and the second heat exchange section 32 is interconnected.

[0074] Optionally, the movable air duct partition 4 also includes a partition drive motor for driving the rotatable partition 41 to rotate.

[0075] Optionally, when the rotatable partition 41 is in the closed state, the rotatable partition 41 is horizontal; when the rotatable partition 41 is in the open state, the rotatable partition 41 is vertical. Optionally, the rotation angle of the rotatable partition 41 from the closed state to the open state is greater than or equal to 90°.

[0076] Optionally, the surface area of ​​the rotatable partition 41 is greater than or equal to the opening area of ​​the partition air passage 411. Thus, when the rotatable partition 41 is in the closed state, it can completely block the partition air passage 411. Optionally, the rotatable partition 41 can function as a damper for the partition air passage 411.

[0077] Optionally, the movable air duct baffle 4 includes a first baffle portion 401 and a second baffle portion 402, and the first baffle portion 401 is close to the heat exchanger 3, wherein a rotatable baffle 41 is formed in the first baffle portion 401; and / or, a first fan 21 is disposed on the upper side of the second baffle portion 402.

[0078] The movable air duct baffle 4 is divided into a first baffle portion 401 near the heat exchanger 3 and a second baffle portion 402 away from the heat exchanger 3. A rotatable baffle 41 is formed in the first baffle portion 401 near the heat exchanger 3, and a first fan 21 is disposed on the upper side of the second baffle portion 402. Figure 3 and Figure 6 As shown. It is understood that the dividing line between the first partition section 401 and the second partition section 402 is not fixed. For example, the dividing line can be the straight line where the partition shaft 414 of the rotatable partition 41 is located. In this way, the arrangement of the first fan 21 avoids the rotation of the rotatable partition 41.

[0079] Optionally, the rotatable partition 41 includes a first movable plate end 412 near the heat exchanger 3 and a second movable plate end 413 opposite to the first movable plate end 412, wherein the rotatable partition 41 includes a partition shaft 414, and the partition shaft 414 is disposed at the second movable plate end 413.

[0080] The rotatable partition 41 has its partition shaft 414 positioned at the second movable plate end 413, away from the heat exchanger 3. This ensures that when the rotatable partition 41 rotates to the conductive state, it does not obstruct the first heat exchange section 31, facilitating the flow of heat or cold from the first heat exchange section 31 through the partition air vent 411. A partition drive motor is connected to the partition shaft 414 to drive the rotatable partition 41 to rotate.

[0081] Optionally, a reference surface passing through the axis of the second fan 22 and parallel to the partition shaft 414 is a first reference surface 403, the portion between the first reference surface 403 and the heat exchanger 3 is a first side portion 404, and the portion between the first reference surface 403 and the front shell portion 11 of the housing is a second side portion 405, wherein the partition shaft 414 is located on the second side portion 405.

[0082] like Figure 8 and Figure 9 As shown, a reference surface passing through the axis of the second fan 22 and parallel to the partition shaft 414 is designated as the first reference surface 403. The portion between the first reference surface 403 and the heat exchanger 3 is designated as the first side portion 404 inside the housing, and the portion between the first reference surface 403 and the front shell portion 11 of the housing is designated as the second side portion 405 inside the housing. The partition shaft 414 is located in the second side portion 405. This allows at least half of the second fan 22 to correspond to the partition air outlet 411, which is beneficial for the heat or cold energy of the first heat exchange section 31 to flow through the partition air outlet 411.

[0083] Optionally, the vertical projection of the partition air vent 411 is the first projection block 406, and the cross-section of the second fan 22 includes the first fan cross-section S1 falling into the first projection block 406. The total area of ​​the cross-section of the second fan 22 is S, the area of ​​the first fan cross-section is S1, and S1≥0.5S.

[0084] like Figure 10 and Figure 11 As shown, when projected vertically, the partition air vent 411 forms the first projection block 406. In the vertical direction, the second fan 22 has a first fan cross section S1 that falls into the first projection block 406. In this embodiment, S1 ≥ 0.5S, so that at least half of the second fan 22 can correspond to the partition air vent 411, which is beneficial for the heat or cold of the first heat exchange section 31 to flow through the partition air vent 411.

[0085] Optionally, the first fan 21 includes a first fan housing 211, and the first fan housing 211 includes a first fan side shell 2111 with a first impeller air inlet 212, wherein the first fan side shell 2111 is parallel to the partition shaft 414 of the rotatable partition 41.

[0086] like Figure 3 and Figure 12 As shown, the first fan side shell 2111 of the first fan 21 is parallel to the partition shaft 414 of the rotatable partition 41. In this way, while increasing the opening area of ​​the partition air outlet 411, it is beneficial to the installation of the first fan 21 inside the shell 1, which is beneficial to the miniaturization and thinning of the air conditioning indoor unit and to reducing the width of the air conditioning indoor unit.

[0087] Optionally, when the rotatable partition 41 is in the conducting state, the setting height of the first movable plate end 412 of the rotatable partition 41 is the first height, and the height of the bottom end of the first impeller air inlet 212 is the second height, wherein the first height is higher than the second height.

[0088] In this way, when the rotatable partition 41 is in the conducting state, the rotatable partition 41 can block at least part of the air inlet 212 of the first impeller, preventing the heat generated by the first heat exchange section 31 or the heat from spreading to the air inlet 212 of the first impeller when the first fan 21 is turned off, which is conducive to the heat or cold generated by the first heat exchange section 31 flowing through the partition air inlet 411.

[0089] Optionally, the second fan 22 includes a second fan housing, the distance from the bottom end of the first fan housing 211 to the movable air duct partition 4 is a first distance J1, and the distance from the top end of the second fan housing to the movable air duct partition 4 is a second distance J2, wherein the first distance J1 is greater than or equal to the second distance J2. Figure 13 As shown.

[0090] In this embodiment, the distance between the top of the second fan casing and the movable air duct partition 4 is small. This helps to reduce the length of the flow path between the heat or cold generated by the first heat exchange section 31 and the second fan 22, and helps to send the heat or cold generated by the first heat exchange section 31 out through the side air outlet 103 after passing through the second fan 22.

[0091] Optionally, the indoor unit of the air conditioner also includes an air guide ring assembly 5 and an air deflector assembly 6. The air guide ring assembly 5 is disposed in the first air duct between the first impeller air outlet 213 of the first fan and the front air outlet 102; the air deflector assembly 6 is used to partially block the air guide ring assembly 5 to adjust the air outlet direction of the front air outlet 102.

[0092] Optionally, the air guide ring assembly 5 includes at least two air guide rings that are connected in the middle. Multiple air guide rings are arranged in sequence along the front-back direction or the horizontal direction to form a through air duct. A jet outlet is formed between two adjacent air guide rings. The jet outlet guides the air from the first impeller air outlet 213 of the first fan 21 to the front air outlet 102 to deliver air forward.

[0093] Optionally, the first fan 21 is a centrifugal fan, located at the lower part of the air guide ring assembly 5. Optionally, the first impeller air outlet 213 is perpendicular to the air guide ring assembly 5. The air guide ring has an arc-shaped air guiding surface, and the air blown out of the first impeller air outlet 213 is redirected by the arc-shaped air guiding surface of the air guide ring and then sent out from the front air outlet 102.

[0094] The indoor unit of the air conditioner provided in this embodiment is also provided with a wind deflector assembly 6. The wind deflector assembly 6 is used to block part of the air guide ring assembly 5, so that the air blown out of the first fan air outlet 213 is blown out through the unblocked part of the air guide ring assembly 5, thereby adjusting the air outlet direction of the front air outlet 102.

[0095] Optionally, the wind deflector assembly 6 blocks a portion of the circumferential direction of the air guide ring assembly 5. For example, the wind deflector assembly 6 blocks the lower circumferential part of the air guide ring assembly 5. In this way, the air blown out of the first impeller air outlet 213 is blown out through the upper circumferential part of the air guide ring assembly 5, causing the air blown out of the front air outlet 102 to be angled downwards. Figure 17 As shown. Alternatively, the wind deflector assembly 6 can block the upper circumferential part of the air guide ring assembly 5, so that the air blown out of the first impeller air outlet 213 is blown out through the lower circumferential part of the air guide ring assembly 5, making the direction of the air blown out of the front air outlet 102 tilted upward, as shown. Figure 18 As shown.

[0096] Understandably, the wind deflector assembly 6 can also block the circumferential side of the air guide assembly 5, for example, by blocking the left or right side of the air guide assembly 5, thereby causing the air blown out of the front air outlet 102 to tilt to the right or to the left.

[0097] As can be seen, the air conditioning indoor unit provided in this embodiment, equipped with the wind deflector component 6, can adjust the airflow direction of the front air outlet 102 in various directions, such as up, down, left, and right, thereby increasing the versatility of the airflow direction of the front air outlet 102. Optionally, the wind deflector component 6 can rotate circumferentially around the air guide ring component 5 to block different positions around the circumference of the air guide ring component 5 according to the user's airflow needs, thereby adjusting the airflow direction of the front air outlet 102.

[0098] Furthermore, the wind deflector component 6 is located at the air guide ring component 5. In this way, the air blown out from the first impeller air outlet 213 can be selectively discharged through the unblocked part of the air guide ring component 5 without the problems of wind blockage or large loss of air volume.

[0099] Optionally, the air guide ring assembly 5 includes an outer air guide 51 near the first impeller air outlet 213 and an inner air guide 52 near the front air outlet 102, wherein the wind deflector assembly 6 is disposed on the outer air guide 51 or the inner air guide 52.

[0100] The outer side 51 of the air guide can be understood as the outer ring of the air guide ring assembly 5, and the inner side 52 of the air guide can be understood as the inner ring of the air guide ring assembly 5, such as... Figure 19 As shown. In this embodiment of the disclosure, the wind deflector assembly 6 can be disposed on the inner side 52 or the outer side 51 of the wind guide ring assembly 5 to block the wind from the inner side 52 or the outer side 51. Figure 19 As shown, the wind deflector assembly 6 is located on the outer side 51 of the air guide.

[0101] Optionally, the wind deflector assembly 6 abuts against the outer side 51 or inner side 52 of the air guide ring assembly 5.

[0102] When the wind deflector assembly 6 is positioned on the outer side of the air guide 51, it abuts against the outer side of the air guide 51, which can also be understood as having no airflow gap between them. Similarly, when the wind deflector assembly 6 is positioned on the inner side of the air guide 52, it abuts against the inner side of the air guide 52, again meaning there is no airflow gap between them. This improves the shielding effect of the wind deflector assembly 6 on the portion of the air guide ring assembly 5 that is blocked.

[0103] Optionally, the air guide ring assembly 5 includes an air guide portion and a shielding portion that forms a shield with the wind deflector assembly 6. The air blown out of the first impeller air outlet 213 is directed by the air guide portion of the air guide ring assembly 5 and then sent out from the front air outlet 102. The length formed by the shielding portion is the shielding length L0, the circumferential length of the air guide ring assembly 5 is L, and 0.25L≤L0≤0.8L.

[0104] The air guide ring in the air guide ring assembly 5 is circular, and the corresponding wind deflector assembly 6 is a partial arc segment of the circle; for example, the wind deflector assembly 6 is an annular baffle. It can be understood that the blocking length L0 formed by the blocking portion is the same as the arc length of the wind deflector assembly 6, such as... Figure 20 As shown in Figure A. The air guide portion of the air guide ring assembly 5 is the part not obstructed by the wind deflector assembly 6, and the length of the air guide portion is Lf, as shown in Figure A. Figure 20 As shown in Figure B, the circumferential length L of the air guide ring assembly 5 is the sum of L0 and Lf.

[0105] Understandably, the wind deflector component 6 can block different positions around the air guide ring component 5 according to the user's airflow direction requirements, and the part not blocked by the wind deflector component 6 is the air guide part. That is, the air guide part and the blocking part of the air guide ring component 5 are not fixed.

[0106] Optionally, the shielding length L0 can be 0.25L, 0.4L, 0.5L, 0.75L, or 0.8L, etc.

[0110] like Figure 16 and Figure 19 As shown, the first track 71 is a circular groove track, and the first end 601 of the rotatable plate assembly is provided with a protrusion that can rotate within the first track 71. Optionally, a rack is provided at the protrusion of the first end 601 of the rotatable plate assembly.

[0111] Optionally, the air guide ring assembly 5 includes a first air guide end 53 near the front shell portion 11 and a second air guide end 54 opposite to the first air guide end 53.

[0112] A fixed air duct baffle 8 is provided on one side of the second air guide end 54 of the air guide ring assembly 5. Optionally, the fixed air duct baffle 8 is arranged vertically. The second track 81 is a circular track groove formed in the fixed air duct baffle 8, such as... Figure 16 As shown, the second end 602 of the rotatable plate assembly is inserted into the grooved second track 81, which improves the rotational stability and shielding stability of the rotatable plate assembly. Optionally, the fixed air duct partition 8 has a certain thickness, which can appropriately increase the opening depth of the second track 81.

[0113] Optionally, the fixed air duct baffle 8 includes a bottom baffle 801 located at the lower part, wherein the first impeller air outlet 213 is installed at a height higher than the bottom baffle 801.

[0114] like Figure 21 As shown, the first impeller air outlet 213 is set at a height higher than the bottom end 801 of the fixed air duct partition 8. In this way, the air blown out by the first impeller air outlet 213 can be concentrated and sent to the air guide ring assembly 5, and can selectively flow out from the air guide part of the air guide ring assembly 5.

[0115] Optionally, the rotatable plate assembly includes a first rotating plate 61 and a second rotating plate 62.

[0116] In this embodiment of the disclosure, the rotatable plate assembly includes a first rotating plate 61 and a second rotating plate 62. Optionally, the first rotating plate 61 and the second rotating plate 62 are not connected to each other and can be driven to rotate by different motors.

[0117] Optionally, the first rotating plate 61 and the second rotating plate 62 can be driven to rotate to adjacent positions, so that the first rotating plate 61 and the second rotating plate 62 abut against each other and work together to adjust the air outlet direction of the front air outlet 102, such as... Figure 22 As shown in B.

[0118] Optionally, the first rotating plate 61 can be driven to rotate to a first position of the air guide ring assembly 5, and the second rotating plate 62 can be driven to rotate to a second position of the air guide ring assembly 5, wherein the first rotating plate 61 and the second rotating plate 62 are spaced apart. The first rotating plate 61 and the second rotating plate 62 give the air guide ring assembly 5 two mutually spaced air guide sections. The air blown out of the first impeller air outlet 213 can be directed through these two mutually spaced air guide sections, thereby improving the versatility of the wind deflector assembly 6 in adjusting the air outlet direction of the front air outlet 102. Figure 22 As shown in Figure A.

[0119] Optionally, the first rotating plate 61 can be driven to rotate to a first position of the air guide ring assembly 5, and the second rotating plate 62 can be driven to rotate to a third position that at least partially overlaps with the first rotating plate 61. Optionally, the second rotating plate 62 can overlap with the first circumferential end of the first rotating plate 61 to adjust the air outlet direction of the front air outlet 102, and the size of the overlap between the second rotating plate 62 and the first rotating plate 61 can be further adjusted to adjust the air outlet range under that air outlet direction; similarly, the second rotating plate 62 can overlap with the second circumferential end of the first rotating plate 61 to adjust the air outlet direction of the front air outlet 102, and the size of the overlap between the second rotating plate 62 and the first rotating plate 61 can be further adjusted to adjust the air outlet range under that air outlet direction. Figure 23 As shown.

[0120] Optionally, the drive rotation assembly includes a first drive motor for driving the first rotating plate 61 to rotate, and a second drive motor for driving the second rotating plate 62 to rotate.

[0121] The first drive motor and the second drive motor are used to drive the first rotating plate 61 and the second rotating plate 62 to rotate, so that the first rotating plate 61 and the second rotating plate 62 cooperate to achieve different air outlet directions of the front air outlet 102.

[0122] Optionally, the first rotating plate 61 forms a first blocking length L1 on the air guide ring assembly 5, the second rotating plate 62 forms a second blocking length L2 on the air guide ring assembly 5, and the circumferential length of the air guide ring assembly 5 is L, wherein 0.25L≤L1<0.5L; and / or 0.25L≤L2<0.5L.

[0123] It is understood that the first blocking length L1 is the arc length of the first rotating plate 61, and optionally, L1 can be 0.25L, 0.3L or 0.4L; similarly, the second blocking length L2 is the arc length of the second rotating plate 62, and L2 can be 0.25L, 0.3L or 0.4L.

[0124] Optionally, L1 > L2.

[0125] In this embodiment, the first blocking length L1 of the first rotating plate 61 is greater than the second blocking length L2 of the second rotating plate 62. In this way, the second rotating plate 62 can serve as an extension plate or a micro-adjustment plate of the first rotating plate 61. The air outlet direction of the front air outlet 102 can be adjusted by the first rotating plate 61, and the air outlet range of the front air outlet 102 under the air outlet direction can be adjusted by adjusting the overlapping position and overlapping area of ​​the second rotating plate 62 with the first rotating plate 61 in the circumferential direction.

[0126] Optionally, the rotation trajectory of the first rotating plate 61 is a first rotation trajectory, and the rotation trajectory of the second rotating plate 62 is a second rotation trajectory, wherein the first rotation trajectory is located outside the second rotation trajectory.

[0127] The first rotation trajectory is a first circle, and the second rotation trajectory is a second circle. The first rotation trajectory may overlap with the second rotation trajectory, such as... Figure 22 As shown. Optionally, the first rotation trajectory can also be located outside the second rotation trajectory, so that the first rotation trajectory and the second rotation trajectory do not overlap, thereby allowing the first rotating plate 61 and the second rotating plate 62 to rotate to a position where they at least partially overlap, as shown. Figure 23 As shown.
