[0042] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this 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.

[0043] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0044] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0045] Obviously, the embodiments described above are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0046] In order to solve the problem that condensation is easily generated on the air guide plate of the air conditioner in the prior art, the present invention provides an air conditioner and an operating method thereof.

[0047] like Figures 1 to 2 、 Figures 4 and 5 As shown, the air conditioner includes a housing 10, an air guide assembly 30, and an anti-condensation structure. The housing 10 has an air outlet 11, and an air duct 20 is provided inside the housing 10, with the end of the air duct 20 connected to the air outlet 11. The air guide assembly 30 is movably arranged at the air outlet 11 and has a blocking position for blocking the air outlet 11 and a evacuation position for avoiding the air outlet 11. When the air guide plate 31 of the air guide assembly 30 is in the evacuation position, the surface of the air guide plate 31 facing the back side of the housing 10 is a first air guide surface 311. The anti-condensation structure is movably arranged at the end of the air duct 20 and is located on the bottom side of the air outlet 11. The side surface of the anti-condensation structure facing the inside of the air duct 20 is a second air guide surface 41. Condensation on the air guide plate 31 is reduced by changing the angular relationship between the first air guide surface 311 and the second air guide surface 41. Specifically, the housing 10 includes a bottom shell 12 and a panel body 13. The bottom shell 12 and the panel body 13 cooperate to form the air outlet 11.

[0048] The air conditioner is provided with a shell 10, an air guide assembly 30 and an anti-condensation structure, the shell 10 has an air outlet 11, and an air duct 20 is arranged in the shell 10, and the end of the air duct 20 is connected to the air outlet 11, and the air guide assembly 30 is movably arranged at the air outlet 11 and has a blocking position blocking the air outlet 11 and a avoidance position avoiding the air outlet 11. When the air guide plate 31 of the air guide assembly 30 is in the avoidance position, the surface of the air guide plate 31 facing the back side of the shell 10 is the first air guide surface 311, and the anti-condensation structure is movably arranged at the end of the air duct 20 and located at the bottom side of the air outlet 11, and the side surface of the anti-condensation structure facing the air duct 20 is the second air guide surface 41. By changing the angular relationship between the first air guide surface 311 and the second air guide surface 41, the wind receiving area of ​​the air guide plate 31 is increased, and condensation is avoided as much as possible in the places on the air guide plate 31 that were not blown by the wind, thereby reducing condensation on the air guide plate 31.

[0049] like Figures 1 to 5 As shown, the anti-condensation structure includes a cover plate 40. The first side of the cover plate 40 is adjacent to the bottom edge of the air duct 20, and the second side of the cover plate 40 extends toward the air outlet 11. The cover plate 40 is movably arranged. It is understandable that the first side of the cover plate 40 is the side close to the bottom shell 12, and the second side is the side close to the air outlet 11. Specifically, the first side of the cover plate 40 is a pivotal side, and the distance between the second side of the cover plate 40 and the bottom edge of the housing 10 is adjusted as the cover plate 40 moves. In this embodiment, the bottom shell 12 has a semicircular groove corresponding to the first side of the cover plate 40. Accordingly, the first side of the cover plate 40 is semicircular and extends into the semicircular groove of the bottom shell 12, thereby being pivotally connected to the bottom shell 12. Through the above arrangement, it can be ensured that there is no step difference at the joint between the first side of the cover plate 40 and the bottom shell 12 during operation, thereby avoiding uneven air discharge.

[0050] like Figures 1 to 5 As shown, the upper surface of the cover plate 40 is a second air guide surface 41. In this embodiment, the second air guide surface 41 is a plane. Of course, the second air guide surface 41 can also be an arc-shaped surface connected in sequence with the air duct 20, which can be selected according to actual needs.

[0051] In this embodiment, the second side of the cover plate 40 overlaps the bottom edge of the air outlet 11 and is located in the initial position. When the anti-condensation structure is activated, the second side of the cover plate 40 is separated from the bottom edge of the air outlet 11 and forms a preset distance with the bottom edge of the air outlet 11, so that the cover plate 40 is in the anti-condensation position. Figure 4As shown, when the cover plate 40 is in the initial position, horizontal line a represents the position where the air blown by the air conditioner can reach the air guide plate 31; when the cover plate 40 is in the anti-condensation position, horizontal line b represents the position where the air blown by the air conditioner can reach the air guide plate 31. This shows that after the cover plate 40 is rotated from the initial position to the anti-condensation position, the air blown by the air conditioner can reach a farther position of the air guide plate 31 under the action of the second air guide surface 41, thereby increasing the wind receiving area of ​​the air guide plate 31 and minimizing condensation in areas of the air guide plate 31 that are not reached by the wind.

[0052] In this embodiment, the second side of the cover plate 40 is engaged with the bottom edge stop of the air outlet 11. Figure 3 As shown, the lower surface of the second side of the cover plate 40 has a stop section 42, and the bottom of the housing 10, located at the edge of the air outlet 11, has a stop step 131. Specifically, the stop step 131 is located on the panel body 13. When the cover plate 40 is in the initial position, the stop section 42 engages with the stop step 131. This arrangement forms a trapezoidal groove structure with the opening facing forward, preventing condensation from entering the panel body 13 and preventing condensation from forming on the panel body 13.

[0053] like Figure 3 As shown, a guide surface 48 is formed between the end of the second side of the cover plate 40 and the stop section 42. The guide surface 48 extends downward at an angle. Furthermore, the connecting surface between the guide surface 48 and the second air guide surface 41 is an inclined surface, and the inclined surface and the guide surface 48 form a pointed shape toward the air outlet 11.

[0054] In this embodiment, when the cover plate 40 is in the initial position, the distance L1 between the stop section 42 and the edge of the air outlet 11 ranges from 0.5 mm to 1 mm, and the vertical distance L2 between the edge of the air outlet 11 and the guide surface 48 ranges from 1 mm to 2 mm.

[0055] like Figure 3 and Figure 5 As shown, the upper surface of the second side of the cover plate 40 has an air guide rib 43. Specifically, the cross section of the air guide rib 43 is triangular, and an angle α is formed between the side surface of the air guide rib 43 facing the interior of the air duct 20 and the upper surface of the cover plate 40, and the angle α is an obtuse angle.

[0056] In this embodiment, if the angle α is too small, the wind will not be able to reach the lower edge of the wind deflector 31 and will not play the role of preventing condensation. If it is too large, the effect of changing the wind direction will be poor. Therefore, the range of the angle α is set to 120° to 150°. Figure 5As shown, position c is the position where the air blown by the air conditioner can reach the air guide plate 31 when the air guide ribs 43 are not installed, and position d is the position where the air blown by the air conditioner can reach the air guide plate 31 after the air guide ribs 43 are installed. The air guide ribs 43 can change the direction of the wind. After the air guide ribs 43 are installed, the direction of part of the wind can be changed, so that the wind that originally only blows to the air guide plate position c can now blow to both position c and position d. This increases the wind receiving area of ​​the air guide plate 31, making it less likely to cause condensation.

[0057] like Figure 3 As shown, since the air guide ribs 43 are also visible appearance parts, they should not be too high to affect the appearance. Therefore, the height H of the air guide ribs 43 is set to range from 0.3 mm to 0.5 mm.

[0058] like Figures 6 and 7 As shown, the air guiding rib 43 has a groove 431, which connects the side surface of the air guiding rib 43 facing the inside of the air duct 20 with the side surface of the air guiding rib 43 facing away from the inside of the air duct 20, so that the groove 431 has a diversion effect.

[0059] Specifically, there are multiple grooves 431 , and the multiple grooves 431 are arranged at intervals along the extension direction of the air guide rib 43 .

[0060] In this embodiment, since a too large width of the groove 431 will lead to uneven overall air output and easily produce a whistling sound, and a too small width will not have the effect of diverting the wind, the width L3 of each groove 431 in the extension direction of the wind guide rib 43 is set to a range of 1mm to 3mm.

[0061] In this embodiment, a guide structure is provided on the inner surface of the side wall of the housing 10, and at least a portion of the cover plate 40 is connected to the guide structure so that the cover plate 40 can move along the guide direction of the guide structure. Figures 1 to 2 、 Figures 4 and 5 As shown, the guide structure includes a slide rail 50 , which is an arc-shaped rail. The cover plate 40 has a sliding member 44 , which extends into the slide rail 50 to enable the cover plate 40 to move along the extension direction of the slide rail 50 .

[0062] In this embodiment, the sliding member 44 is cylindrical, and the diameter of the sliding member 44 is smaller than the width of the slide rail 50. Specifically, the gap between the sliding member 44 and the inner wall of the slide rail 50 is between 0.05 mm and 0.1 mm, so that the sliding member 44 can slide freely and smoothly in the slide rail 50.

[0063] like Figure 6 and Figure 8As shown, the anti-condensation structure also includes a driving part 60, which is located at one end of the cover plate 40. The driving part 60 includes a driving motor 61 and a driving shaft 62. The shell 10 is provided with a first matching hole corresponding to the other end of the cover plate 40. The two ends of the cover plate 40 respectively have a matching rotating shaft 45 and a second matching hole 46 coaxially arranged with the driving shaft 62. The matching rotating shaft 45 extends into the first matching hole, and the driving shaft 62 extends into the second matching hole 46, so that the driving part 60 drives the cover plate 40 to rotate.

[0064] In this embodiment, the second fitting hole 46 is elliptical, and the fitting clearance with the driving shaft 62 is about 0.05 mm.

[0065] like Figure 6 and Figure 8 As shown, the cover plate 40 also has at least one auxiliary shaft 47. The interior of the housing 10 has a protrusion 122 extending toward the cover plate 40. Specifically, the protrusion 122 is located on the bottom shell 12 and defines a rotation hole. At least a portion of the auxiliary shaft 47 is located within the rotation hole. In this embodiment, there are two auxiliary shafts 47, spaced apart in the middle of the cover plate 40. Accordingly, there are also two protrusions 122, corresponding to the two auxiliary shafts 47. This arrangement allows the cover plate 40 to rotate more stably relative to the bottom shell 12, thereby achieving an anti-condensation effect.

[0066] like Figure 9 As shown, the present application also provides an operating method for an air conditioner, the air conditioner is the above-mentioned air conditioner, and the operating method includes: when the air guide plate 31 of the air guide assembly 30 of the air conditioner is in a fixed state, monitoring whether the air guide plate 31 is in a preset condensation angle range; only when the air guide plate 31 is in the preset condensation angle range, adjusting the cover plate 40 of the anti-condensation structure of the air conditioner to rotate from the initial position to the anti-condensation position.

[0067] In this embodiment, the operating method further includes monitoring whether the air guide plate 31 is within the preset condensation angle range only when the air conditioner is in the cooling state. It is understandable that in the cooling state, the inner and outer surfaces of the air guide plate 31 are more likely to have a temperature difference.

[0068] In this embodiment, Figure 4 The angle β between the air deflector 31 and the vertical direction is shown. The operating method also includes the step of determining a preset condensation angle, which includes: the preset condensation angle is the angle β between the air deflector 31 and the vertical direction. In other words, before controlling the rotation of the cover plate 40, the operating method of the air conditioner of the present application needs to determine whether the air deflector 31 is at an angle that is likely to cause condensation.

[0069] Specifically, the angle β ranges from 36° to 48°.

[0070] In this embodiment, Figure 4 The angle γ of movement of the cover plate 40 between the anti-condensation position and the initial position is shown. The operating method also includes the step of setting the range of the angle of movement of the cover plate 40, which includes setting the range of the angle γ of movement of the cover plate 40 between the anti-condensation position and the initial position to 7° to 9°. Within this range, the windshield 31's windward area can be maximized, minimizing condensation in areas of the windshield 31 previously unreachable by the wind, thereby reducing condensation on the windshield 31.

[0071] From the above description, it can be seen that the above embodiment of the present invention achieves the following technical effects: by setting the air conditioner including a shell 10, an air guide component 30 and an anti-condensation structure, the shell 10 has an air outlet 11, an air duct 20 is provided in the shell 10, the end of the air duct 20 is connected to the air outlet 11, the air guide component 30 is movably arranged at the air outlet 11 and has a blocking position for blocking the air outlet 11 and a avoidance position for avoiding the air outlet 11. When the air guide plate 31 of the air guide component 30 is in the avoidance position, the air guide plate 31 of the air guide component 30 is in the avoidance position. When in the position, the surface of the air guide plate 31 facing the back side of the shell 10 is the first air guide surface 311, the anti-condensation structure is movably arranged at the end of the air duct 20 and located on the bottom side of the air outlet 11, and the surface of the anti-condensation structure facing the side of the air duct 20 is the second air guide surface 41. By changing the angular relationship between the first air guide surface 311 and the second air guide surface 41, the wind receiving area of ​​the air guide plate 31 is increased, and condensation is avoided as much as possible in the places on the air guide plate 31 that were not blown by the wind, thereby reducing condensation on the air guide plate 31.
