However, when the air conditioner is cooling, the air deflector is cooled by the cold air, causing indoor water vapor to condense on it, affecting user experience.

[0003] Therefore, improvements to existing technologies are necessary.

[0004] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Utility Model Content

Detailed Implementation

[0030] To illustrate the possible application scenarios, technical principles, implementable specific solutions, and achievable objectives and effects of this application in detail, the following description, in conjunction with the listed specific embodiments and accompanying drawings, provides a detailed explanation. The embodiments described herein are merely illustrative of the technical solutions of this application and are therefore intended to limit the scope of protection of this application.

[0031] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features.

[0032] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0033] This application provides an air guide plate, an air guide structure, and an air conditioner to solve the problem of condensation on the air guide plate. The following description will be provided in conjunction with the accompanying drawings.

[0034] Please see Figure 1 This application provides an air guide plate, including an air guide plate body 1. The air guide plate body 1 is provided with an air guide component 11 and an air guide surface 12. The air guide component 11 is disposed on the air guide side of the air guide plate body 1. The side of the air guide component 11 away from the air guide plate body 1 is provided with an air guide surface 111 for guiding the airflow away from the air guide side. The air guide surface 12 connects the windward end of the air guide plate body 1 and the leeward side of the air guide plate.

[0035] By providing an air guide 11 on the air guide side of the air guide plate body 1, and providing an air guide surface 111 on the air guide 11 to guide the airflow away from the air guide side, the airflow flowing through the air guide surface 111 deviates from the air guide side of the air guide plate body 1, which helps to reduce the heat exchange between the airflow and the air guide plate body 1, thereby reducing condensation on the windward side of the air guide plate body 1; by providing an air intake surface 12 at the windward end of the air guide plate body 1, and using the air intake surface 12 to guide part of the airflow blowing to the air guide plate body 1 to flow through the leeward side of the air guide plate body 1, it helps to reduce the occurrence of condensation on the leeward side of the air guide plate body 1 due to water vapor contacting the low temperature air guide plate, thus solving the problem of air guide plate condensation.

[0036] Please see Figure 1 The air guide plate is arranged in a long strip shape. The air guide side of the air guide plate body 1 refers to the side where the airflow needs to be guided away after passing through the air guide plate. The leeward side refers to the side opposite to the air guide side. The windward end refers to the end of the air guide plate body 1 that the airflow first contacts. Specifically, in this embodiment, one side of the air guide plate in the thickness direction is the air guide side, and the other side in the thickness direction is the leeward side. One end of the air guide plate in the width direction is the windward end, and the other end in the width direction is the leeward end. The air guiding direction of the air guide plate body 1 is from the windward end to the leeward end.

[0037] Please see Figure 1The air guide plate has multiple support seats 13 integrally formed on its air guide side. The support seats 13 are used to connect with an external drive mechanism so that the external drive mechanism can drive the air guide plate to move. In this embodiment, the number of support seats 13 is set to three, and the three support seats 13 are equally spaced along the length direction of the air guide plate body 1.

[0038] Please see Figure 1 An air guide 11 is disposed on the air guide side of the air guide plate body 1. The air guide 11 is integrally formed with the air guide plate body 1. In this embodiment, the number of air guides 11 is set to two. One air guide 11 is fixedly connected to a support base 13 located at one end of the length direction of the air guide plate body 1, and the other air guide 11 is fixedly connected to a support base 13 located at the other end of the length direction of the air guide plate. An air guide surface 111 is provided on the side of the air guide 11 away from the air guide plate body 1. In this embodiment, the air guide surface 111 is an inclined surface that gradually moves away from the air guide side of the air guide plate body 1 along the air guide direction of the air guide plate body 1. In this embodiment, the air guide surface 111 is a concave curved surface or an outward curved surface. The setting of the air guide surface 111 can guide the airflow away from the air guide surface 111 on the air guide side, so that the airflow flowing through the air guide surface 111 deviates from the air guide side of the air guide plate body 1, which helps to reduce the heat exchange between the airflow and the air guide plate body 1, thereby reducing condensation on the windward side of the air guide plate body 1.

[0039] Please see Figure 1 The air guide 11 has multiple first condensation grooves 112, which are used to collect condensation that forms on the windward end of the air guide plate body 1. In this embodiment, four first condensation grooves 112 are provided, extending along the length of the air guide 11. The four first condensation grooves 112 are arranged at intervals along the air guiding direction of the air guide plate body 1. In this embodiment, the width of the first condensation groove 112 is 1.5 mm. In some embodiments of this application, the width of the first condensation groove 112 is 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, and 2 mm. By making the width of the first condensation groove 112 between 1 mm and 2 mm, it is not only beneficial for the first condensation groove 112 to collect condensation, but also beneficial to reduce the impact of the opening of the first condensation groove 112 on the air guiding performance of the air guide 11.

[0040] Please see Figure 1 The air-guiding surface 12 connects the windward end of the air guide plate body 1 and the leeward side of the air guide plate body 1. In this embodiment, the air-guiding surface 12 is a smoothly transitioned curved surface. The air-guiding surface 12 is used to guide part of the airflow blowing onto the air guide plate body 1 through the leeward side of the air guide plate body 1, which helps to reduce the occurrence of condensation on the leeward side of the air guide plate body 1 caused by water vapor contacting the low-temperature air guide plate.

[0041] Please see Figure 1 The air guide plate also includes an insulation pad 2, which is adhered and fixed to the air guide side of the air guide plate body 1. The insulation pad 2 is used to isolate the air guide plate body 1 from the external environment and reduce condensation. The insulation pad 2 can be made of sponge, rubber, silicone, or other materials with good thermal insulation properties. A waterproof layer is provided on the side of the insulation pad 2 away from the air guide plate body 1. The function of the waterproof layer is to prevent external moisture from seeping into the insulation pad 2 and affecting the thermal insulation effect, and also to prevent any condensation that may occur inside the insulation pad 2 from seeping out.

[0042] Please see Figure 1 and Figure 2 The air guide plate body 1 has a baffle rib 14 on its air guide side. The baffle rib 14 is a protruding structure on the edge of the air guide side of the air guide plate body 1. In this embodiment, the baffle rib 14 includes a first baffle part 141, a second baffle part 142, and a third baffle part 143. The first baffle part 141 is located on the other side of the width direction of the air guide plate body 1. There are two second baffle parts 142, which are respectively located at both ends of the length direction of the air guide plate body 1. One end of the second baffle part 142 is fixedly connected to the first baffle part 141, and the other end is fixedly connected to the support base 13. The third baffle part 143 is connected to the two air guide components 11. The first baffle part 141, the second baffle part 142, the third baffle part 143, the support base 13, and the air guide components 11 together define the heat insulation groove 16, and the heat insulation pad 2 is disposed in the heat insulation groove 16. The height of the enclosure rib 14 is the same as the thickness of the insulation pad 2, so as to fix the insulation pad 2. The insulation groove 16 formed between the enclosure rib 14 and the air guide 11 is used to accommodate the insulation pad 2. The depth of the insulation groove 16 matches the thickness of the insulation pad 2, and the shape of the insulation pad 2 corresponds to the shape of the insulation groove 16.

[0043] Please see Figure 1 and Figure 2 The air guide plate body 1 has an integrally formed condensation element 15 on its air guide side. The condensation element 15 connects the enclosure rib 14 and the air guide plate body 1. In this embodiment, there are three condensation elements 15. Specifically, one condensation element 15 is located on the side of the first enclosure 141 away from the insulation groove 16, and the other two condensation elements 15 are respectively located on the side of the two second enclosures 142 away from the insulation groove 16. The condensation element 15 can collect the condensate generated at the edge of the air guide plate body 1.

[0044] Please see Figure 1 and Figure 2 In addition, an air guide 1411 is provided on the first enclosure 141, and the air guide 1411 is directly opposite the middle support 13 to compensate for the decrease in the uniformity of air outlet of the air guide plate caused by the obstruction of the support 13.

[0045] Please see Figure 3This application embodiment also provides an air guide structure, which includes an air guide plate as described above, a base 3, and a middle frame 4. An air duct 31 is formed on the base 3, and an air outlet 41 is opened on the middle frame 4. The air duct 31 is connected to the air outlet 41. The middle frame 4 is disposed on the base 3, and the air guide plate is disposed at the air outlet 41.

[0046] Please see Figure 3 and Figure 4 Multiple airflow guide ribs 32 are integrally formed on the side wall of the air duct 31. These ribs extend along the opening direction of the air duct 31 and are spaced apart along the length of the base 3. The airflow guide ribs 32 are strip-shaped structures installed within the air duct 31 to guide airflow along the extension direction of the air duct 31, reducing turbulence and energy loss within the air duct 31. The airflow guide ribs 32 can be straight, curved, or other shapes, designed according to the shape of the air duct 31 and the characteristics of the airflow.

[0047] Please see Figure 3 and Figure 5 The middle frame 4 is mounted on the base 3 and can be fixedly connected to the base 3 by clips, screws, or other means. An air outlet 41 is provided on the middle frame 4, which is an opening through which airflow exits from the air guide structure. The air duct 31 is connected to the air outlet 41, allowing airflow to flow from the air duct 31 to the air outlet 41. An air guide plate is positioned at the air outlet 41, with its windward end facing the air outlet 41, so that the airflow first contacts the windward end of the air guide plate and then flows to the leeward end under the guidance of the air intake surface 12.

[0048] Please see Figure 5 and Figure 6 A flow-through element 42 is provided on the middle frame 4. The flow-through element 42 is used to guide the airflow from the air outlet 41 to the air guide plate. A flow-through surface 43 is provided on the side of the flow-through element 42 away from the middle frame 4 to guide the airflow to the air guide plate. The flow-through surface 43 on the side of the flow-through element 42 away from the middle frame 4 is inclined to guide the airflow to the air guide plate. The shape and angle of the flow-through surface 43 are designed according to the characteristics of the airflow and the position of the air guide plate to ensure that the airflow can flow smoothly to the air guide plate.

[0049] Please see Figure 5 and Figure 6 One sidewall of the flow-through component 42 is connected to the sidewall of the air outlet 41. A third condensation groove 44 is provided on the sidewall where the flow-through component 42 connects to the air outlet 41, and / or a third condensation groove 44 is provided on the sidewall where the air outlet 41 connects to the flow-through component 42. The function of the third condensation groove 44 is to collect condensation generated during the airflow process. The third condensation groove 44 can be provided on the sidewall where the flow-through component 42 connects to the air outlet 41, or on the sidewall where the air outlet 41 connects to the flow-through component 42, or both.

[0050] Please see Figure 5 and Figure 6 A flow channel 45 is formed on the flow-through component 42. The bottom of the flow channel 45 connects to the bottom of the third condensation tank 44 and the flow surface 43. The flow channel 45 is a groove-shaped structure formed on the flow-through component 42 to guide the condensation on the flow surface 43 into the third condensation tank 44. The bottom of the flow channel 45 is connected to the bottom of the third condensation tank 44 and the flow surface 43 to form a continuous water flow channel, allowing the condensate to flow smoothly and preventing water accumulation.
