[0084] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0085] like Figures 1 to 10 As shown, the first embodiment of the present invention provides a wind sweeping component 10, which includes: a wind sweeping connecting rod 11 and a mounting member 12 arranged at intervals, and a plurality of wind sweeping blades 13 arranged at intervals along the extension direction of the wind sweeping connecting rod 11, each wind sweeping blade 13 includes a rotating shaft 131, a first flexible connecting part 132, a blade body 133 and a second flexible connecting part 134 connected in sequence, the rotating shaft 131 is fixedly connected to the mounting member 12, and one end of the second flexible connecting part 134 extends out of the mounting member 12 and is fixedly connected to the wind sweeping connecting rod 11. The wind sweeping component 10 is an integrally formed structure.

[0086] With such a structural setting, through the one-piece wind sweeping component 10, there is no need to install the wind sweeping blades 13 individually, and only the wind sweeping component 10 needs to be installed as a whole. The structure is simple and the installation is convenient, which improves the installation efficiency of the wind sweeping component 10. In addition, through the setting of the first flexible connection part 132 and the second flexible connection part 134, it is possible to easily realize the rotational wind sweeping of the wind sweeping blades 13 to ensure the wind sweeping effect. The wind sweeping component 10 in this embodiment can be used on the left and right, can be rotated and installed interchangeably, and can be mirrored up and down. Since the wind sweeping component 10 in this embodiment is an integrated structure, the number of parts of the wind sweeping component 10 is reduced, and the mold opening cost is reduced. Specifically, the wind sweeping component 10 in this embodiment is used to sweep the wind up and down, and the wind sweeping blades 13 realize the up and down swinging wind sweeping.

[0087] Specifically, the thickness of the first flexible connection portion 132 is less than or equal to the thickness of the blade body 133 , which can facilitate deformation at the first flexible connection portion 132 , so as to drive the wind sweeping blade 13 to rotate.

[0088] The thickness of the first flexible connection portion 132 is less than or equal to the thickness of the rotating shaft 131 , so that deformation can occur at the first flexible connection portion 132 , so as to drive the wind sweeping blade 13 to rotate.

[0089] The thickness of the second flexible connection portion 134 is less than or equal to the thickness of the blade body 133 , so that deformation can occur at the second flexible connection portion 134 , so as to drive the wind sweeping blade 13 to rotate.

[0090] In this embodiment, the thickness of the first flexible connection portion 132 is b1, 0.45 mm ≤ b1 ≤ 0.6 mm, so that deformation can occur at the first flexible connection portion 132, and bending can occur easily when subjected to force, so as to drive the wind sweeping blade 13 to rotate. In addition, by setting the thickness of the first flexible connection portion 132 within the above range, it is also possible to avoid the situation where it is easy to break due to repeated bending and deformation, which can meet the flexibility requirements and improve the reliability of the structure.

[0091] Specifically, the thickness of the second flexible connection portion 134 is b2, 0.45 mm ≤ b2 ≤ 0.6 mm, which can facilitate deformation at the second flexible connection portion 134, and bend easily when subjected to force, so as to drive the wind sweeping blade 13 to rotate. In addition, by setting the thickness of the second flexible connection portion 134 within the above range, it is also possible to avoid the situation where it is easy to break due to repeated bending and deformation, which can meet the flexibility requirements and improve the reliability of the structure.

[0092] Specifically, the wind sweeping blade 13 is made of polyethylene material and polypropylene material, so as to be flexible and deformable at the first flexible connection part 132 and the second flexible connection part 134 to reduce abnormal noise. The thinner material (thickness between 0.45 mm and 0.6 mm can be understood as thinner) of such material is soft, and the thicker material is relatively hard.

[0093] Through the above-mentioned design of the flexible structure and related characteristic dimensions of the sweeping blade 13, the reliability of the sweeping air supply can be achieved through appropriate thickness, size and characteristics, abnormal noise and vibration can be improved, the use of silicone grease of the sweeping blade 13 can be reduced, and the service life and reliability of the sweeping blade 13 can be improved. In addition, under certain conditions, the sweeping blade can be combined with a specific program control to optimize the comfort of air supply and avoid water blowing from the air outlet affecting use.

[0094] In this embodiment, the wind sweeping component 10 is installed on the air duct component 20, and the wind sweeping blades 13 are located at the air outlet gap of the air duct component 20. In this way, it is convenient to sweep the wind better and improve the wind sweeping effect.

[0095] Specifically, the mounting member 12 is mounted on the volute tongue 21 of the air duct component 20 to facilitate installation.

[0096] Specifically, one end of the rotating shaft 131 is fixedly connected to the mounting member 12 , and the other end of the rotating shaft 131 abuts against the volute 22 of the air duct component 20 , so as to ensure the setting stability of the other end of the rotating shaft 131 .

[0097] Specifically, the rotating shaft 131 is supported between the volute tongue 21 and the volute 22 to ensure that the rotating shaft 131 can rotate stably and to ensure that the support stability of the air duct component 20 is improved.

[0098] In this embodiment, the sweeping blade 13 has a first sweeping surface and a second sweeping surface arranged opposite to each other, and an anti-condensation through hole penetrating the first sweeping surface and the second sweeping surface is arranged on the sweeping blade 13 to facilitate anti-condensation. Specifically, such a setting can prevent condensation water from forming on the leeward side of the sweeping blade 13, thereby preventing water from blowing and affecting the user experience.

[0099] Specifically, a water diversion groove is provided on the wind sweeping blade 13, and one end of the water diversion groove is connected to or arranged opposite to the wind sweeping connecting rod 11, so as to facilitate the water on the wind sweeping blade 13 to be led to the wind sweeping connecting rod 11 through the water diversion groove, and to the bottom through the vertically placed wind sweeping connecting rod 11, and flow into the water receiving groove located at the bottom of the wind sweeping connecting rod 11, so as to facilitate the collection of condensed water and prevent water blowing.

[0100] Specifically, the wind sweeping blade 13 has a first wind sweeping surface and a second wind sweeping surface which are arranged opposite to each other.

[0101] The first flexible connection portion 132 is provided with a first anti-condensation through hole 1321 penetrating the first wind sweeping surface and the second wind sweeping surface for anti-condensation. Specifically, such a configuration can prevent condensation water from forming on the leeward side of the wind sweeping blade 13, thereby preventing water from affecting the user experience.

[0102] A second anti-condensation through hole 1331 penetrating the first wind sweeping surface and the second wind sweeping surface is provided on one side of the blade body 133 close to the second flexible connecting portion 134, so as to facilitate anti-condensation.

[0103] In this embodiment, a connecting hole 111 is provided on the wind sweeping connecting rod 11, and the wind sweeping component 10 further includes a latch 14, which is inserted into the connecting hole 111 to facilitate the connection between the wind sweeping connecting rod 11 and other components.

[0104] Specifically, the latch 14 of one wind sweeping component 10 is plugged into the connecting hole 111 of the wind sweeping connecting rod 11 of another wind sweeping component 10, so that the two wind sweeping components 10 can be spliced ​​together according to the length of the air outlet gap.

[0105] Specifically, there are at least two latches 14 and at least two connecting holes 111. At least two latches 14 are arranged in one-to-one correspondence with at least two connecting holes 111. Each latch 14 is inserted into the corresponding connecting hole 111 to improve the splicing stability of the two spliced ​​wind sweeping components 10. This can also facilitate the formation of an interlocking structure of two adjacent wind sweeping components 10, and the splicing and extension can be performed according to actual needs. Specifically, the latch 14 can adopt a mushroom head structure, which can be limited by the mushroom head when the latch is inserted into another wind sweeping component 10, and locked at the same time, which is equivalent to achieving fixation in the linear direction. Correspondingly, the connecting hole 111 can also be used as a hole for driving and connecting with the driving member 30.

[0106] The wind sweeping component 10 in this embodiment is connected by a flexible structure, and the vibration will be buffered by the flexible structure, thereby effectively avoiding abnormal noise.

[0107] like Fig.11 As shown, the second embodiment of the present invention provides an air conditioner indoor unit, which includes an air duct component 20 and the above-mentioned wind sweeping component 10 installed on the air duct component 20.

[0108] The air conditioner indoor unit in this embodiment further includes a door panel component 60, a panel 70, an air outlet frame assembly 80, a lower panel component 90, a chassis component 100, an evaporator component 110 and an air inlet panel component 120. The air inlet panel component 120 is used for air intake, and the evaporator component 110 is arranged in a space surrounded by the door panel component 60, the panel 70, the lower panel component 90, the chassis component 100 and the air inlet panel component 120, and the door panel component 60 is movably arranged.

[0109] Specifically, the wind sweeping component 10 is located at the front side of the air duct component 20, which is equivalent to the rear side of the air outlet frame. The air is first swept up and down and then swept left and right, which has a better up and down sweeping effect. The wind sweeping component 10 is a whole and can be assembled in an integrated manner, which is more efficient. Fig.10 The four wind sweeping blades and four volute tongue parts shown in the figure are all the same and can be used interchangeably.

[0110] Specifically, the air duct component 20 includes a volute 22 and a volute tongue 21 , and the wind sweeping component 10 is disposed at an air outlet gap between the volute 22 and the volute tongue 21 .

[0111] The mounting member 12 of the wind sweeping component 10 is provided with a first mounting portion 121, and the volute tongue 21 is provided with a second mounting portion 211 adapted to the first mounting portion 121. The first mounting portion 121 is installed and matched with the second mounting portion 211, so that the mounting member 12 is installed on the volute tongue 21. In this way, the installation stability of the wind sweeping component 10 is improved.

[0112] Specifically, one of the first mounting portion 121 and the second mounting portion 211 is a clamping member, and the other of the first mounting portion 121 and the second mounting portion 211 is a clamping groove, which has a simple structure and stable installation. The above structure can realize the overall assembly of the wind sweeping component 10 without the need for perforation and assembly, thereby improving assembly efficiency.

[0113] Specifically, the clamping piece may be a buckle structure.

[0114] Specifically, a mounting groove 212 matching the shape of the mounting member 12 is provided on the volute tongue 21 , the mounting member 12 is installed in the mounting groove 212 , and the second mounting portion 211 is installed in the mounting groove 212 to further improve the installation stability of the mounting member 12 .

[0115] In this embodiment, the air duct component 20 also includes a fan blade 23, which is located between the volute 22 and the volute tongue 21; the volute tongue 21 includes a main body 213, the second mounting portion 211 is arranged on the main body 213, and the mounting member 12 is installed on the main body 213.

[0116] Among them, the volute tongue 21 also includes a first protrusion 214, which is arranged at the first end of the main body 213 and protrudes from the side of the main body 213 close to the fan blade 23, so as to reduce the gap between the volute tongue 21 and the fan blade 23 where the wind sweeping blade 13 is not provided, so as to facilitate better air discharge, increase the air discharge speed, reduce the air discharge noise, and realize the structure of the noise-reducing volute tongue, thereby reducing the surging problem caused by the speed difference with other positions.

[0117] Specifically, the volute tongue 21 further includes a second convex portion 215, which is disposed at the second end of the main body 213 and protrudes from the side of the main body 213 close to the fan blade 23. With such a configuration, it is possible to reduce the gap between the volute tongue 21 and the fan blade 23 where the wind sweeping blade 13 is not disposed, so as to better discharge air, increase the discharge speed, reduce the discharge noise, and thus reduce the surging problem caused by the speed difference with other positions.

[0118] Specifically, the diameter of the fan blade 23 in this embodiment is D.

[0119] The gap between the first protrusion 214 and the fan blade 23 is d1, 0.05≤d1 / D≤0.07, so that the gap between the first protrusion 214 and the fan blade 23 is within the optimal gap range, so as to better improve the air outlet speed and reduce the air outlet noise.

[0120] The gap between the second protrusion 215 and the fan blade 23 is d2, 0.05≤d2 / D≤0.07, so that the gap between the second protrusion 215 and the fan blade 23 is within the optimal gap range, so as to better improve the air outlet speed and reduce the air outlet noise.

[0121] like Fig. 9 As shown, when two volute tongues 21 are spliced, the first convex portion 214 of the upper volute tongue 21 is located at the upper edge of the air outlet gap, and the second convex portion 215 of the upper volute tongue 21 is located between the two wind sweeping components 10; the first convex portion 214 of the lower volute tongue 21 is located between the two wind sweeping components 10, and the second convex portion 215 of the lower volute tongue 21 is located at the lower edge of the air outlet gap. In this way, the gap between the upper and lower edges of the air outlet gap is reduced, and the wind speed can be increased by reducing the gap.

[0122] In this embodiment, the air duct component 20 further includes air duct reinforcing ribs 24, which are supported at the air outlet gap to improve the structural stability of the air duct component 20 and avoid the situation where the air outlet gap is too long and thus leads to poor structural strength.

[0123] Specifically, at least two wind sweeping components 10 are provided at the air outlet gap, at least two wind sweeping components 10 are spliced ​​and installed at the air outlet gap, and the air duct reinforcement rib 24 is located at the gap between two adjacent wind sweeping components 10. In this way, the structural strength of the air duct component 20 at the air outlet gap where the wind sweeping component 10 is not provided is improved.

[0124] Specifically, a volute 22 and a volute tongue 21 may be provided at an air outlet gap.

[0125] Alternatively, two volutes 22 and two volute tongues 21 may be provided at one air outlet gap. When two volutes 22, two volute tongues 21, and two wind sweeping components 10 are provided at one air outlet gap, each volute 22 cooperates with the corresponding volute tongue 21 and is provided with a corresponding wind sweeping component 10. During actual installation, the two volutes 22 are installed along the installation direction of the two wind sweeping components 10, and the two volute tongues 21 are installed along the installation direction of the two wind sweeping components 10. In this case, the air duct reinforcement rib 24 is also located between the two volute tongues 21. Specifically, the two volutes 22 are installed on the volute surface, and the two volute tongues 21 are installed on the volute tongue mounting bracket.

[0126] Specifically, the air duct component 20 includes at least two volutes 22 and at least two volute tongues 21. The at least two volutes 22 are arranged in a one-to-one correspondence with the at least two volute tongues 21. Each volute 22 cooperates with the corresponding volute tongue 21 to form a corresponding air outlet gap. In this way, a double air duct structure is formed. Specifically, the double air duct structure in this embodiment is a double cross-flow air duct structure.

[0127] Alternatively, at least two volutes 22 are arranged at intervals along a preset direction, and at least two volute tongues 21 are arranged at intervals along a preset direction, and at least two volutes correspond to at least two volute tongues one by one to cooperate to form an air outlet gap. In this way, the situation where a single volute 22 and a single volute tongue 21 are arranged too long is avoided. By arranging them at intervals along a preset direction, it can also play a role in accommodating the thermal deformation of the volute 22 and the volute tongue 21 (that is, when the air conditioner is heating, the volute tongue 21 and the volute 22 become longer, and a certain accommodation gap is required). Specifically, the two ends of the air duct reinforcement rib 24 are respectively located between the gaps of the two volutes 22 and between the gaps of the two volute tongues 21.

[0128] Specifically, the indoor unit of the air conditioner has two air outlets, which are respectively located on both sides. A volute 22, a volute tongue 21 and an air sweeping component 10 are correspondingly provided at each air outlet.

[0129] In this embodiment, the air conditioner indoor unit further includes a driving member 30 and a driving rod 40. The driving end of the driving member 30 is rotatably arranged and drivingly connected to the driving rod 40. The driving rod 40 is hinged to the wind sweeping connecting rod 11. Specifically, the driving member 30 can be a motor.

[0130] Among them, the driving rod 40, the part of the wind sweeping link 11 corresponding to the hinge between the driving rod 40 and the wind sweeping link 11 and one end of the second flexible connection part 134, the connecting line between one end of the second flexible connection part 134 and the connection between the rotating shaft 131 and the mounting member 12, and the connecting line between the connection between the rotating shaft 131 and the mounting member 12 and the driving end form a parallelogram (so that the driving member 30 will drive the parallelogram (similar to the four-bar linkage) to move when rotating and driving). In this way, the driving stability is improved, the driving effect is improved, and the rotation in the up and down directions is realized.

[0131] Specifically, the air conditioner indoor unit further comprises a mounting cover 50 mounted on the air duct component 20, and the driving member 30 is mounted on the mounting cover 50. In this way, the mounting stability of the driving member 30 is better improved.

[0132] Specifically, the air-conditioning indoor unit in this embodiment may be an air-conditioning cabinet unit.

[0133] The "up and down direction" in this embodiment can be understood as the height direction of the air conditioner indoor unit.

[0134] The third embodiment of the present invention provides a control method, which is used for the above-mentioned wind sweeping component 10, and the control method includes: obtaining the temperature and humidity at the wind sweeping blade 13 of the wind sweeping component 10 and the working time of the wind sweeping blade 13 in the corresponding wind sweeping mode; controlling the movement of the wind sweeping blade 13 according to the temperature and / or humidity at the wind sweeping blade 13 and / or the working time of the wind sweeping blade 13 in the corresponding wind sweeping mode. In this way, the wind sweeping component 10 can be controlled to prevent condensation.

[0135] In this embodiment, the sweeping blade 13 is controlled according to the temperature and humidity of the sweeping blade 13, including: when the temperature at the sweeping blade 13 is lower than the condensation temperature, the humidity at the sweeping blade 13 is higher than the preset humidity, and the working time of the sweeping blade 13 in the corresponding sweeping mode is higher than the preset time, the sweeping blade 13 is controlled to rotate to a downward inclined drainage angle; after the sweeping blade 13 rotates to the downward inclined drainage angle, the sweeping blade 13 is controlled to sweep and drain at a preset frequency within a preset angle range. In this way, the water on the sweeping blade 13 is first introduced into the sweeping connecting rod 11, and the water is introduced to the water receiving tray component at the bottom through the numerically set sweeping connecting rod 11, so as to reduce the situation of blowing water when the wind is discharged.

[0136] Specifically, the temperature at the sweeping blade 13 is Tn, the humidity at the sweeping blade 13 is Vn, the working time corresponds to the usage time Tt, and the condensation temperature is also the dew point temperature T1. The dew point temperature T1 can be calculated according to the corresponding relationship in the specific table.

[0137] Specifically, the wind sweeping blade 13 is controlled to sweep and drain water at a preset frequency within a preset angle range. Since a water diversion groove is provided on the wind sweeping blade 13, one end of the water diversion groove is connected to or arranged opposite to the wind sweeping connecting rod 11, it is convenient for water droplets to stay along the rod to the bottom of the air duct and be discharged along the drainage structure. The high-frequency shaking is equivalent to throwing water off. Specifically, one or more water diversion grooves can be provided on the wind sweeping blade 13.

[0138] Specifically, the drainage angle is greater than the maximum normal wind sweeping angle of the wind sweeping blade 13 to facilitate better drainage.

[0139] The minimum value of the preset angle range is greater than the maximum angle value of the normal wind sweeping blade 13 to facilitate better drainage.

[0140] The preset frequency is greater than the normal sweeping frequency of the sweeping blade 13 so as to better vibrate the water on the sweeping blade 13 to drain downward.

[0141] Specifically, the humidity is preset to 80% to facilitate accurate anti-condensation control.

[0142] The preset time is 30 minutes to facilitate accurate anti-condensation control.

[0143] The drainage angle is 60° to allow water to drain accurately.

[0144] The preset angle range is 55° to 65°, so as to better drain the water on the wind sweeping blade 13 .

[0145] The preset frequency is 8 ms per step to better discharge the water vibration on the wind sweeping blade 13.

[0146] Preferably, when Tn<T1, Vn>80%, Tt>30min, anti-condensation control is performed, otherwise the detection is returned and repeated.

[0147] Specifically, after controlling the sweeping blade 13 to sweep air and drain water at a preset frequency within a preset angle range, the control method further includes: obtaining the operation time of the sweeping blade 13 at a preset frequency within the preset angle range, and when the operation time is greater than the predetermined time, controlling the sweeping blade 13 to return to the original sweeping mode, so as to return to the normal operation mode.

[0148] Specifically, the predetermined time length may be set to 1 minute.

[0149] It should be noted that the “original sweeping mode” may be understood as the sweeping mode of the sweeping component 10 before the sweeping component 10 is controlled to prevent condensation.

[0150] like Fig.12 As shown, when the temperature is lower than the dew point temperature in the room, condensation water is easily accumulated on the surface of the wind sweeping blade 13 when supplying air. When the wind speed is high, water blowing will occur. By combining the condensation logic, the anti-condensation effect is optimized to avoid blowing water affecting the user experience. Specifically, first check whether there is up and down wind sweeping and the position of the wind guide plate (if there is no up and down wind sweeping, the condensation effect will be relatively good, if the up and down wind sweeping is upward or downward, condensation will be verified, the horizontal position of the wind sweeping blade 13 is judged as state A, and the non-horizontal position of the wind sweeping blade 13 is judged as state B); then, judge the current humidity and temperature, the ambient temperature is lower than the condensation temperature, and when the humidity is >80%, the time is >30min, the drainage mode is started in state A, and the time is >60min in state B; then, when the drainage mode is started, the fan speed is reduced (100-300rpm), and the up and down wind sweeping angle is lowered to 60° (normal up and down wind sweeping is generally -45°, +45°, and the horizontal is 0°) and then, within this range, the wind is swept at a high frequency of 5°, the speed is 8ms per step (normal up and down wind sweeping is 12ms per step) and finally: the duration is 1min, and then it is restored to the original wind sweeping state, and the fan speed returns to the original speed.

[0151] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: solving the problems of the traditional wind sweeping blade 13 with many parts and high failure rate, high versatility and expansibility, can be applied to the air duct components 20 in different situations, has a good wind guiding effect, and combined with the volute tongue 21 can improve the abnormal noise problem in the use of air conditioning, and effectively reduces costs, improves efficiency, and has high reliability.
