[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] Since the air guide strips in the related art gradually become thinner in the width direction, the air guide strips may be severely bent and deformed due to the uneven volume shrinkage, which may not only cause uneven air supply of the air conditioner but also reduce the indoor temperature regulation effect during use.

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

[0039] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0040] As people's living standards improve, household appliances play an increasingly important role in their daily lives. Air conditioners in household appliances can be divided into wall-mounted air conditioners, floor-standing air conditioners (cabinet air conditioners) and commercial air conditioners according to the installation location and usage scenarios. Air conditioners generally include cooling mode, heating mode, dehumidification mode, etc. Based on the aesthetic performance and cooling / heating performance of air conditioners, floor-standing air conditioners (cabinet air conditioners) are currently being used more and more widely. For floor-standing air conditioners (cabinet air conditioners), when the floor-standing air conditioner (cabinet air conditioner) is in working mode, the air guide strip at the air outlet will rotate to the left and right to open the air outlet, and the airflow blown out by the floor-standing air conditioner (cabinet air conditioner) changes the air supply direction by the left and right swing of the air guide strip.

[0041] Combination Figure 1 As shown, in the related art, in order to reduce the airflow resistance when the outlet airflow flows through the air guide strip, when the air conditioner is running, the air guide strip is gradually thinned in the direction toward the inside of the air conditioner.

[0042] However, since the air guide strip in the related art gradually becomes thinner in the width direction, the air guide strip may be severely bent and deformed due to the uneven volume shrinkage, which may not only cause uneven air supply of the air conditioner but also reduce the effect of regulating the indoor temperature.

[0043] Therefore, the embodiments of the present disclosure provide an air guide strip, an air guide assembly, and an air conditioner indoor unit to improve the structural strength of the air guide strip, reduce deformation, and improve the uniformity of the air supply airflow.

[0044] Combination Figures 2 to 5 As shown, the wind guide strip provided by the embodiment of the present disclosure includes a wind guide strip body 100. The wind guide strip body 100 extends vertically, including a leeward end 110 and a windward end 120, wherein the wind guide strip body 100 maintains the same thickness from the windward end 120 to the leeward end 110.

[0045] Optionally, the air guide strip body 100 is formed by extending in the vertical direction, and the vertical direction of the air guide strip body 100 is the length direction of the air guide strip body 100. The air guide strip body 100 includes a leeward end 110 and a windward end 120, wherein the direction from the windward end 120 to the leeward end 110 is the width direction of the air guide strip body 100. The windward end 120 refers to the end of the air guide strip body 100 facing the direction of the airflow when the air guide strip body 100 is arranged in the vertical direction, and the direction from the windward end 120 to the leeward end 110 is the flow direction of the airflow.

[0046] Optionally, the air guide strip body 100 is an injection molded part.

[0047] The deformation of injection molded products generally refers to the distortion phenomenon that the product obtained after molding deviates from the original design shape of the product, including distortion of product size, distortion of shape contour and distortion of angle. Common types of deformation include warping, bending, dimensional tolerance, abnormal assembly gap, etc. The uneven shrinkage of the material of injection molded products is the main cause of deformation. Some uneven shrinkage is caused by product design. The main factors affecting shrinkage in product design include product wall thickness, geometry, rib distribution, column position design, etc. Under normal circumstances, an increase in wall thickness will lead to an increase in shrinkage; on the other hand, uneven wall thickness changes will lead to different shrinkage rates in different areas, causing product deformation.

[0048] Therefore, in order to prevent the air guide strip body 100 from being deformed in the length direction due to uneven contraction, the air guide strip body 100 is set to maintain the same thickness from the windward end 120 to the leeward end 110. In this way, the bending deformation of the air guide strip body can be reduced or even avoided, thereby improving the uniformity of the airflow passing through the air guide strip, thereby improving the uniformity of indoor temperature regulation.

[0049] When air flows through the air guide strip body 100, if the air guide strip body 100 forms a certain angle with the flow direction of the air flow, the air flow first contacts the windward end 120 of the air guide strip body 100, and the air guide strip body 100 can guide the air flow to change the flow direction of the air flow. In this way, by setting the air guide strip body 100 to maintain the same thickness from the windward end 120 to the leeward end 110, the air flow flowing through the side of the air guide strip body 100 can be kept uniform in the vertical direction.

[0050] In addition, since the bending deformation of the air guide bar body can be reduced or even avoided, the structural stability of the air guide bar can be improved, the structural stability of the air outlet path can be ensured, and the noise generated by the deformation of the air guide bar body 100 can be avoided, thereby improving the user experience.

[0051] Optionally, when a plurality of air guide strip bodies 100 are arranged in parallel, a guide channel is formed between adjacent air guide strip bodies 100 to allow air flow to pass through.

[0052] With the air guide strip provided by the embodiment of the present disclosure, both the windward end and the leeward end are side ends extending vertically. By setting the air guide strip body to maintain the same thickness from the windward end to the leeward end, the shrinkage rate of different areas of the air guide strip body due to uneven wall thickness changes can be avoided, thereby reducing or even avoiding the bending deformation of the air guide strip body, thereby improving the uniformity of the air flow through the air guide strip, and further improving the uniformity of indoor temperature regulation. In addition, since the bending deformation of the air guide strip body can be reduced or even avoided, the structural stability of the air guide strip can be improved, the structural stability of the air outlet path can be ensured, and the noise generated by the deformation of the air guide strip body can be avoided, thereby improving the user experience.

[0053] Optionally, the wind guide strip further includes a guide section 130 and a spoiler 140. The guide section 130 is fixedly connected between the windward end 120 and the leeward end 110, and includes a first side surface 131 and a second side surface 132 opposite to each other, and the first side surface 131 and the second side surface 132 extend vertically; the spoiler 140 is arranged on the first side surface 131 and / or the second side surface 132.

[0054] Optionally, the thickness of the guide section 130 is consistent with the thickness of the windward end 120 and the leeward end 110 to ensure the overall consistency of the wind guide strip.

[0055] Optionally, the windward end 120 , the guide section 130 and the leeward end 110 are integrally formed to improve structural strength and structural stability.

[0056] Optionally, when air flows through the air guide strip body 100, if the air guide strip body 100 forms a certain angle with the flow direction of the air flow, the air flow first contacts the windward end 120 of the air guide strip body 100, and the air flow flows through the guide section 130 to the leeward end 110, thereby achieving a guiding effect on the air flow.

[0057] Optionally, a spoiler 140 is provided on the first side 131 and / or the second side 132 of the guide section 130 extending vertically to prevent a strong airflow from blowing directly at the target. The target mentioned here may be a target user, a target object, or a target space. If the target is the target user, the airflow blowing directly at the user may cause discomfort to the user. The spoiler 140 provided on the first side 131 and / or the second side 132 may break up the airflow flowing through the first side 131 and / or the second side 132. Under the action of the spoiler 140, the turbulence of the airflow is increased, and the softness of the airflow is increased to improve the comfort of the airflow when blowing toward the target user.

[0058] In addition, the spoiler 140 can cause the airflow to form turbulence on the first side 131 and / or the second side 132 to increase the contact area between the airflow and the first side 131 and / or the second side 132 and improve fluidity to avoid the formation of condensation water on the first side 131 and / or the second side 132.

[0059] Optionally, the spoiler 140 includes a spoiler protrusion.

[0060] Optionally, the spoiler protrusion is a semicircular arc shape, a semi-elliptical shape, or a semi-polygonal shape. Specifically, the spoiler protrusion can be a part of a sphere, a part of an ellipsoid, or a part of a polygon. Preferably, the spoiler protrusion is in an arc shape or an elliptical shape. When the spoiler protrusion is circular or elliptical, the airflow is subjected to less resistance, and the flow velocity of the airflow will not be reduced due to the spoiler protrusion, so that the spoiler can be formed without reducing the flow velocity. Optionally, the spoiler protrusion is integrally formed with the guide section 130 for easy processing.

[0061] Optionally, the spoiler 140 includes a spoiler groove.

[0062] Optionally, the spoiler groove is a semicircular groove or a semi-elliptical groove. Specifically, the airflow flows along the windward end 120 through the first side 131 and the second side 132 of the guide section 130, and at the same time, under the action of its own fluid viscosity, it flows along the first side 131 / the second side 132 and the guide groove. The flow direction of the airflow passing through the spoiler groove is different from the flow direction of the airflow flowing along the first side 131 / the second side 132, and collision mixing can be achieved at the leeward end 110 to form a slight up and down oscillation flow effect, thereby being able to disturb the airflow flowing along the first side 131 / the second side 132, thereby making the airflow softer.

[0063] Optionally, the spoiler 140 includes spoiler protrusions and spoiler grooves. The spoiler protrusions and spoiler grooves are alternately arranged at intervals to increase the turbulence of the airflow.

[0064] Optionally, the air guide strip further includes a first purification coating. The first purification coating is coated on the surface of the air guide strip body 100 .

[0065] Specifically, the first purification coating is a silver ion air purification film layer. In this way, the air guide strip body 100 can be provided with a purification function, so that the airflow passing through the air guide strip body 100 can be purified, thereby improving the cleanliness of the airflow and the comfort of the user.

[0066] Optionally, the air guide strip body 100 itself may also have a purification function, that is, when the air guide strip body 100 is produced, a material containing silver ions is mixed into the production material. In this way, the air guide strip body 100 after molding itself has a purification function, thereby purifying the airflow passing through the air guide strip body 100.

[0067] Optionally, the air guide strip further comprises air guide vanes 200. A plurality of air guide vanes 200 are vertically spaced apart and arranged at the leeward end 110, and the air guide vanes 200 are connected to the air guide strip body 100 at an angle, wherein an air guide channel 210 is formed between adjacent air guide vanes 200.

[0068] Optionally, the air guide blade 200 extends along the width direction of the air guide strip body 100. By providing a plurality of air guide blades at the leeward end 110, the softness of the airflow flowing through the air guide strip can be further improved. Since the air guide blade 200 is connected to the air guide strip body 100 at an angle, the direction of the airflow flowing out of the leeward end 110 of the air guide strip body 100 can be changed, and the air guide blade 200 has a certain cross-sectional area, when the airflow hits the air guide blade 200, it can form a certain obstruction to the airflow, thereby improving the softness of the airflow.

[0069] Optionally, an air guide channel 210 is formed between adjacent air guide blades 200. In this way, the airflow flowing out of the leeward end 110 of the air guide strip body 100 can be dispersed into a plurality of air guide channels 210 to further improve the softness of the airflow.

[0070] Optionally, the air guide strip further includes a connecting plate 300. The connecting plate 300 is used to connect the air guide blade 200 and the air guide strip body 100.

[0071] By providing the connecting plate 300, the connection area between the air guide blade 200 and the air guide strip body 100 can be increased, thereby preventing the air guide blade 200 from being deformed under the impact of airflow for a long time, or avoiding the risk of fracture at the connection between the air guide blade 200 and the air guide strip body 100, thereby improving the structural stability and safety of the air guide blade 200.

[0072] Optionally, the air guide strip further includes a second bactericidal coating. The second bactericidal coating is coated on the surface of the air guide blade 200.

[0073] Specifically, the second bactericidal coating is a silver ion air purification film layer. In this way, the air guide blade 200 can be provided with a purification function, so that the airflow passing through the air guide blade 200 can be purified, thereby improving the cleanliness of the airflow and the comfort of the user.

[0074] Optionally, the guide blade 200 itself may also have a purification function, that is, when the guide blade 200 is produced, a material containing silver ions is mixed into the production material, so that the formed guide blade 200 itself has a purification function, thereby purifying the airflow passing through the guide blade 200.

[0075] Optionally, the air guide strip body 100 , the air guide blades 200 and the connecting plate 300 are integrally formed to facilitate processing and manufacturing and reduce costs.

[0076] The disclosed embodiment of the present invention discloses an air guide assembly, including the air guide strip as described above.

[0077] Optionally, the wind guide assembly includes one or more rotatably connected wind guide strips, and the wind guide assembly has a first state and a second state. In the first state, a plurality of wind guide strip bodies 100 are arranged in sequence along their width direction; in the second state, a plurality of wind guide strip bodies 100 are arranged in parallel, and a guide channel is formed between adjacent wind guide strip bodies 100, so as to change the direction of the airflow flowing through the wind guide assembly and improve the softness of the airflow.

[0078] The air guide assembly provided by the embodiment of the present disclosure includes an air guide bar body having a windward end and a leeward end extending vertically. By setting the air guide bar body to maintain the same thickness from the windward end to the leeward end, the shrinkage rate of different areas of the air guide bar body due to uneven wall thickness changes can be avoided, thereby reducing or even avoiding the bending deformation of the air guide bar body, thereby improving the uniformity of the air flow through the air guide bar, and further improving the uniformity of indoor temperature regulation. In addition, since the bending deformation of the air guide bar body can be reduced or even avoided, the structural stability of the air guide bar and the air guide assembly can be improved, the structural stability of the air outlet path can be ensured, and the noise generated by the deformation of the air guide bar body can be avoided, thereby improving the user experience.

[0079] The disclosed embodiment of the present invention discloses an indoor unit of an air conditioner, comprising an air guide assembly as described above.

[0080] Optionally, the indoor unit of the air conditioner is a cabinet air conditioner, comprising a housing, on which an air outlet extending vertically is disposed, and the aforementioned air guide assembly is disposed at the air outlet. In the first state, the air guide assembly closes the air outlet; in the second state, the air guide assembly opens the air outlet, adjusts the flow direction of the airflow out of the air outlet, and improves the softness of the airflow.
