Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and more specifically, to a sweeping blade and an air conditioner. Background Technology

[0002] In the air conditioning industry, during cooling, hot and cold air converge at the air duct outlet, and condensation gradually accumulates on the surface of objects. For example, in the normal cooling mode of a floor-standing air conditioner, condensation may form on the air guide vanes.

[0003] Currently, there is no special method for dealing with the condensation generated by the air guide vanes at the air outlet of the cabinet air conditioner. The condensation that is formed is either blown out directly or drips onto the bottom surface of the vanes and cannot be discharged, resulting in water accumulation in the guide rail groove of the moving door (e.g. Figure 1 If water cannot be drained for a long time, it may breed bacteria and mosquitoes, resulting in a poor customer experience. Utility Model Content

[0004] This invention solves the problem of condensation water droplets not being able to drain or overflowing outside the air conditioner from the bottom of the air outlet frame, and can smoothly drain condensation water to avoid water accumulation.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] In one aspect, the present invention provides a sweeping blade, including a sweeping blade body, the sweeping blade body including a plurality of horizontal grilles spaced apart along the vertical direction and a plurality of vertical blades spaced apart along the horizontal direction, the plurality of horizontal grilles and the plurality of vertical blades being staggered, and a water-receiving surface for collecting condensate is formed on the bottom horizontal grilles, and a drainage notch is provided on the inner edge of the water-receiving surface for discharging the condensate on the water-receiving surface inward.

[0007] The sweeping blade provided in this embodiment has a water-receiving surface formed on the bottom horizontal grille to collect condensate, and a drainage notch is provided on the inner edge of the water-receiving surface. In actual use, condensation occurs on the horizontal grille and vertical blades due to the convergence of warm and cold air. The condensate flows downwards to the water-receiving surface on the bottom horizontal grille, where it gathers and flows out through the drainage notch. Because the drainage notch is located on the inner side, the condensate can be directly discharged into the air conditioning duct, where it is collected by the water-receiving tray at the bottom of the duct, preventing condensate from dripping onto the air outlet frame at the bottom of the sweeping blade body. Compared to the prior art, this invention, by designing a water-receiving surface and drainage notch on the bottom horizontal grille, can discharge condensate inwards, preventing water accumulation at the bottom of the air outlet. Therefore, it can smoothly discharge condensate, solving the problem in the prior art where condensate droplets on the bottom surface of the air outlet frame cannot be discharged or overflow outside the air conditioner.

[0008] In an optional embodiment, the projections of the horizontal grid and the vertical blade above the water-receiving surface along the vertical direction are both located within the water-receiving surface.

[0009] The sweeping blade provided in this embodiment of the utility model, by limiting the upper horizontal grid and vertical blades to be located within the water receiving surface, can ensure the water receiving surface's ability to receive condensate, ensuring that the condensate on the sweeping blade body can flow into the water receiving surface, and preventing the condensate from dripping directly downwards.

[0010] In an optional embodiment, the water-receiving surface is inclined toward the drainage gap, and the horizontal height of the bottom edge of the drainage gap is lower than the horizontal height of the water-receiving surface.

[0011] The sweeping blades provided in this embodiment of the utility model are inclined with the water receiving surface facing the drainage gap, and the horizontal height of the drainage gap is minimized. Therefore, all the condensed water can be discharged through the drainage gap, avoiding excessive accumulation of condensed water on the water receiving surface and ensuring smooth drainage.

[0012] In an optional embodiment, the water receiving surface includes a first guide slope and a second guide slope, the first guide slope and the second guide slope are joined together to form a centerline groove, the centerline groove extends to the drainage gap and slopes downward toward the drainage gap, and both the first guide slope and the second guide slope slope downward toward the centerline groove.

[0013] The sweeping blade provided in this embodiment of the utility model utilizes a first guide slope and a second guide slope to form a centerline groove, which can collect the condensate on the first guide slope and the second guide slope into the centerline groove, and then flow from the centerline groove to the drainage gap. This makes the flow guidance of the condensate better and ensures that the condensate on the entire water receiving surface is discharged, avoiding local water accumulation and ensuring the drainage effect.

[0014] In an optional embodiment, the inner edge of the horizontal grille at the bottom is partially raised inward to form an angled portion, and the drainage notch is disposed in the angled portion.

[0015] The sweeping blade provided in this embodiment of the utility model, by designing an angled portion, enables the drainage notch to be located on the inwardly protruding part of the horizontal grille. During the rotation and air guiding process of the sweeping blade, the angled portion can extend inward, thereby enabling the angled portion to move as far as possible within the air conditioning duct range. This ensures that no matter how the air guiding angle changes, the drainage notch will always discharge condensate into the air conditioning duct, guaranteeing the drainage effect and avoiding situations where drainage is impossible at extreme angles.

[0016] In an optional embodiment, the edge of the water-receiving surface is further provided with a water-blocking edge, which is at least distributed on the inner edge of the water-receiving surface and protrudes upward relative to the water-receiving surface, and the drainage notch is provided in the middle of the water-blocking edge.

[0017] The sweeping blades provided in this embodiment of the utility model have a water-blocking edge designed at the edge of the water-receiving surface, which can prevent condensed water from dripping directly downwards from the edge of the water-receiving surface. The drainage notch is set in the middle of the water-blocking edge, which ensures the guiding effect of condensed water, so that all condensed water is discharged from the drainage notch, further ensuring the accuracy of the drainage direction.

[0018] In an optional embodiment, both the first guide slope and the second guide slope extend downwards at an inward angle.

[0019] The sweeping blades provided in this embodiment of the utility model have both the first and second guide slopes set at an inclination, and are set with the outside higher than the inside. On the one hand, this can ensure that the condensate flows from the outside to the inside to the drain gap, and on the other hand, it can prevent the condensate from dripping outward under the action of the airflow, ensuring that the condensate can be discharged into the air conditioning duct through the drain gap.

[0020] In an optional embodiment, the inner edge and / or the outer edge of the vertical blade protrude from the transverse grille.

[0021] The sweeping blades provided in this embodiment of the utility model have vertical blades that protrude inward and outward relative to the horizontal grid, making the width of the horizontal grid above the water receiving surface relatively smaller. This ensures that the condensate on the horizontal grid can flow downward through the vertical blades, avoiding excessive condensation accumulation on the horizontal grid in the area above the water receiving surface.

[0022] In an optional embodiment, the sweeping blade further includes decorative blades disposed on the underside of the sweeping blade body.

[0023] The sweeping blades provided in this embodiment of the utility model, by setting decorative blades, can play a decorative and shielding role, resulting in a better visual experience, and also provide good support for the main body of the sweeping blades, thereby improving the overall structural strength of the sweeping blades.

[0024] On the other hand, the present invention also provides an air conditioner, including an air outlet frame, an air duct housing and the aforementioned air blade frame, wherein an air conditioning air duct is provided inside the air duct housing, the air outlet frame is provided at the air outlet of the air conditioning air duct, and the main body of the air sweeping blade is rotatably mounted on the air outlet frame.

Detailed Implementation

[0037] As disclosed in the background section, such as Figure 1As shown, in the prior art, the air guide vanes are usually not designed with a separate condensation drainage structure. The condensation water in the air duct shell can be discharged through the water collection tray on the bottom side of the air duct shell. However, most of the structure of the air outlet frame and air guide vanes is located outside the water collection tray (i.e. outside the air duct shell). Therefore, the condensation on the air guide vanes will drip directly downwards and only accumulate at the blade mounting structure of the air outlet frame. For example, water may accumulate in the guide rail groove of the movable door. If the water cannot be drained for a long time, it may breed bacteria and mosquitoes, resulting in a poor customer experience.

[0038] To address the aforementioned problems, this utility model provides an air conditioning appliance cover and an air conditioner. To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0039] See Figures 2 to 4 This utility model embodiment provides a sweeping blade 100, which can smoothly discharge condensate to the air conditioning duct 231, avoid condensate accumulation at the bottom of the sweeping blade 100, and reduce the direct outward blowing of condensate.

[0040] This utility model embodiment provides a sweeping blade 100, including a sweeping blade body 110 for rotatably disposed at the air outlet of an air conditioning duct 231. The sweeping blade body 110 includes a plurality of horizontal grilles 111 spaced apart in the vertical direction and a plurality of vertical blades 113 spaced apart in the horizontal direction. The plurality of horizontal grilles 111 and the plurality of vertical blades 113 are staggered, and a water receiving surface 130 for receiving condensate is formed on the bottom horizontal grille 111. The water receiving surface 130 is used to receive condensate on the upper horizontal grille 111 and vertical blades 113, and a drainage notch 132 is provided on the inner edge of the water receiving surface 130 for discharging the condensate on the water receiving surface 130 inward.

[0041] It is worth noting that in this embodiment, the sweeping blade 100 is rotatably mounted on the air outlet frame 210 of the air conditioner 200, and the airflow direction is adjusted by rotation. Its airflow adjustment principle and installation structure can refer to existing sweeping blades. The air conditioning duct 231 is located inside the duct housing 230 of the air conditioner 200, and the sweeping blade body 110 is located at the air outlet of the air conditioning duct 231, enabling adjustment of the airflow direction. A water-receiving surface 130 for collecting condensate is formed on the horizontal grille 111 at the bottom, and a drainage notch 132 is provided on the inner edge of the water-receiving surface 130. In actual use, condensation occurs on the horizontal grille 111 and vertical blades 113 due to the convergence of warm and cold air. The condensate flows downward to the water receiving surface 130, where it is collected and drained out through the drain notch 132. Since the drain notch 132 is located on the inner side, the condensate can be directly discharged into the air conditioning duct 231, where it is collected by the water receiving tray at the bottom of the duct, preventing the condensate from dripping onto the air outlet frame 210 at the bottom of the sweeping blade body 110. Therefore, this embodiment of the invention can discharge the condensate on the sweeping blade body 110 into the air conditioning duct 231, preventing water accumulation at the bottom of the air outlet and ensuring smooth discharge of condensate. This solves the problem in the prior art where condensate dripping onto the bottom surface of the air outlet frame 210 cannot be discharged or overflows outside the air conditioner.

[0042] In some embodiments, the vertical projections of the horizontal grille 111 and vertical blades 113 above the water-receiving surface 130 are both located within the water-receiving surface 130. Specifically, "the vertical projections of the horizontal grille 111 and vertical blades 113 are located within the water-receiving surface 130" means that the vertical projections of the horizontal grille 111 and vertical blades 113 overlap with the vertical projection of the water-receiving surface 130, and the projected size of the water-receiving surface 130 is larger. Furthermore, the distribution range of the horizontal grille 111 and vertical blades 113 above the water-receiving surface 130 is all located within the water-receiving surface 130. By limiting the horizontal grille 111 and vertical blades 113 above the water-receiving surface 130 to be located within the water-receiving surface 130, the water-receiving surface 130's ability to collect condensate can be ensured, guaranteeing that all condensate on the sweeping blade body 110 can flow into the water-receiving surface 130, preventing condensate from dripping directly downwards.

[0043] It should be noted that in this embodiment, the main body 110 of the sweeping blade can be a sweeping blade of uniform width or a sweeping blade of gradually varying width. Regardless of the structure of the blade, most of the condensate on it will flow downwards. Even if a small amount of condensate drips freely downwards under the action of wind, it will drip onto the water receiving surface 130. By setting a water receiving surface 130 with a larger distribution area, the condensate on the main body 110 of the sweeping blade can be completely collected.

[0044] In some embodiments, the water-receiving surface 130 is inclined toward the drain notch 132, and the horizontal height of the bottom edge of the drain notch 132 is lower than the horizontal height of the water-receiving surface 130. Specifically, the drain notch 132 is located at the lowest point of the inner edge, and the entire water-receiving surface 130 is inclined toward the drain notch 132, which minimizes the horizontal height of the drain notch 132. Therefore, condensate can be discharged through the drain notch 132, avoiding excessive accumulation of condensate on the water-receiving surface 130 and ensuring smooth drainage.

[0045] See Figures 5 to 7 In some embodiments, the inner edge of the bottom horizontal grille 111 protrudes inward to form an angled portion 133. Specifically, the inner center of the bottom horizontal grille 111 extends inward and forms an inwardly protruding angled portion 133. A drainage notch 132 is provided in the angled portion 133, and the angled portion 133 is designed to move within the air conditioning duct 231, allowing the drainage notch 132 to discharge condensate into the air conditioning duct 231. Specifically, the angled portion 133 extends towards the inner side of the air conditioning duct 231, forming a sharp angle structure. The drainage notch 132 is located on the inner edge of the angled portion 133, maximizing its orientation towards the inner side of the air conditioning duct 231. Since the entire sweeping blade 100 can rotate, the angled portion 133 is designed so that the drainage notch 132 is located on the inwardly protruding portion of the water-receiving surface 130, and rotation does not affect the drainage function of the drainage notch 132. During the rotation of the sweeping blades 100, the angled portion 133 remains within the air conditioning duct 231, ensuring that no matter how the air guiding angle changes, the drainage notch 132 always discharges condensate into the air conditioning duct 231, thus guaranteeing the drainage effect and avoiding situations where drainage is impossible at extreme angles.

[0046] It should be noted that the protrusion height of the angled part 133 can be set according to the limit rotation angle. As long as it can be ensured that the angled part 133 is still located in the air conditioning duct 231 when the main body of the sweeping blade 110 rotates to the limit angle, that is, to ensure that the drainage gap 132 is always located in the water receiving tray below the air conditioning duct 231.

[0047] See Figure 4 and Figure 5In some embodiments, a water-receiving surface 130 is further provided with a water-blocking edge 134. The water-blocking edge 134 is distributed at least on the inner edge of the water-receiving surface 130 and protrudes upward relative to the water-receiving surface 130. A drainage gap 132 is located in the middle of the water-blocking edge 134. Specifically, the water-blocking edge 134 is integrally provided on the inner edge and the left and right edges of the water-receiving surface 130, which can block and guide the condensed water flowing inward to the drainage gap 132. Therefore, designing a water-blocking edge 134 on the edge of the water-receiving surface 130 can prevent condensed water from dripping directly downward from the edge of the water-receiving surface 130. Moreover, the drainage gap 132 is located in the middle of the water-blocking edge 134, which ensures the guiding effect of condensed water, so that all condensed water is discharged from the drainage gap 132, further ensuring the accuracy of the drainage direction.

[0048] In other preferred embodiments of this utility model, the water-blocking edge 134 may be provided only on the inner edge of the water-receiving surface 130, or the water-blocking edge 134 may be distributed on the four sides of the water-receiving surface 130. Here, the specific arrangement range of the water-blocking edge 134 is not specifically limited.

[0049] See Figure 4 , Figure 5 and Figure 8 In some embodiments, the water-receiving surface 130 includes a first guide slope 135 and a second guide slope 136. The first guide slope 135 and the second guide slope 136 are joined together to form a centerline groove 137. The centerline groove 137 extends to the drainage gap 132 and slopes downward toward the drainage gap 132. Both the first guide slope 135 and the second guide slope 136 slope downward toward the centerline groove 137. Specifically, the first guide slope 135 and the second guide slope 136 are distributed in the left-right direction, and the centerline groove 137 is located at the centerline of the water-receiving surface 130. By splicing the first guide slope 135 and the second guide slope 136 to form a centerline groove 137, the condensed water on the first guide slope 135 and the second guide slope 136 can be collected into the centerline groove 137, and then flow from the centerline groove 137 to the drainage gap 132. This makes the flow guidance of the condensed water better, and can ensure that the condensed water on the entire water receiving surface 130 is discharged, avoiding local water accumulation and ensuring the drainage effect.

[0050] In other preferred embodiments of this utility model, the water receiving surface 130 can also be arc-shaped, with a low center and high edges, and a low inner side and a high outer side, which can also ensure that the condensed water is discharged through the drainage gap 132 after it flows together.

[0051] In some embodiments, both the first guide slope 135 and the second guide slope 136 extend downwards at an inward angle. Specifically, both the first guide slope 135 and the second guide slope 136 have a certain slope in both the inward and outward directions, and the slopes are the same. By setting both the first guide slope 135 and the second guide slope 136 at an inward angle, with the outer side higher than the inner side, it is possible to ensure that the condensate flows from the outside to the inside to the drain opening 132, and to prevent the condensate from dripping outwards under the action of the airflow, ensuring that all the condensate can be discharged into the air conditioning duct 231 through the drain opening 132.

[0052] In some embodiments, the inner and / or outer edges of the vertical blades 113 protrude beyond the horizontal grille 111. Specifically, both the inner and outer edges of the vertical blades 113 protrude beyond the horizontal grille 111. Of course, in other preferred embodiments, the vertical blades 113 may also have either an inner or outer edge protruding beyond the horizontal grille 111. The vertical blades 113 protrude inward and outward relative to the horizontal grille 111, making the width of the horizontal grille 111 relatively smaller. This ensures that the condensate on the horizontal grille 111 can flow downward through the vertical blades 113, avoiding excessive condensation accumulation on the horizontal grille 111.

[0053] It should be noted that the air guiding function is mainly achieved through the vertical blades 113, while the horizontal grilles 111 serve a connecting and structural reinforcement function. The vertical blades 113 are arc-shaped and employ a gradually increasing width construction; that is, along the left-right direction, the width of multiple vertical blades 113 gradually increases to better fit the air outlet. The main body 110 of the sweeping blades can be divided into two connected parts, upper and lower, connected by connecting ribs. Both parts are composed of staggered horizontal grilles 111 and vertical blades 113.

[0054] In some embodiments, the sweeping blade 100 further includes decorative blades 150 disposed on the bottom side of the sweeping blade body 110. Specifically, the left and right width of the decorative blades 150 is smaller than the left and right width of the sweeping blade body 110, and it can be adapted to the bottom width of the air outlet. The decorative blades 150 include decorative horizontal ribs and decorative vertical ribs, which are staggered to form a grille-like air outlet structure at the bottom. By setting the decorative blades 150, a decorative shielding function can be provided, resulting in a better visual experience, and a good supporting function for the sweeping blade body 110, thereby improving the structural strength of the sweeping blade.

[0055] See also Figure 6 , Figure 7 , Figure 9 and Figure 10This utility model embodiment also provides an air conditioner 200, including an air outlet frame 210, an air duct housing 230, and a sweeping blade body 110. The sweeping blade body 110 includes a sweeping blade body 110 for rotatably disposed at the air outlet of the air conditioning air duct 231. The sweeping blade body 110 includes a plurality of horizontal grilles 111 spaced apart along the vertical direction and a plurality of vertical blades 113 spaced apart along the horizontal direction. The plurality of horizontal grilles 111 and the plurality of vertical blades 113 are staggered, and a water receiving surface 130 for receiving condensate is formed on the bottom horizontal grille 111. The water receiving surface 130 is used to receive condensate on the upper horizontal grille 111 and vertical blades 113, and a drainage notch 132 is provided on the inner edge of the water receiving surface 130 for discharging the condensate on the water receiving surface 130 inward. An air conditioning duct 231 is provided inside the duct housing 230, and an air outlet frame 210 is provided at the air outlet of the air conditioning duct 231. The main body 110 of the sweeping blade is rotatably mounted on the air outlet frame 210.

[0056] Furthermore, the top of the sweeping blade body 110 and the bottom of the decorative blade 150 are provided with an assembly structure. The assembly structure can be a positioning column or a positioning sleeve. The assembly structure can be rotatably mounted on the upper and lower frame beams of the air outlet frame 210 to achieve a rotatable connection with the air outlet frame 210.

[0057] In summary, the sweeping blade 100 and air conditioner 200 provided in this embodiment of the present invention form a water-receiving surface 130 on the horizontal grille 111 at the bottom of the sweeping blade body 110, and a drainage notch 132 is provided on the inner edge of the water-receiving surface 130. In actual use, condensation is generated on the sweeping blade body 110 due to the convergence of cold and warm air. The condensed water flows downward to the water-receiving surface 130, and the water-receiving surface 130 collects the condensed water and flows out through the drainage notch 132. Since the drainage notch 132 is located on the inner side, the condensed water can be directly discharged into the air conditioning duct 231 and received by the water receiving tray at the bottom of the duct, thus preventing the condensed water from dripping onto the air outlet frame 210 at the bottom of the sweeping blade body 110. Compared with the prior art, this utility model, by designing a water-receiving surface 130, can discharge condensed water into the air conditioning duct 231, avoiding water accumulation at the bottom of the air outlet and ensuring smooth discharge of condensed water. This solves the problem in the prior art where condensed water droplets on the bottom surface of the air outlet frame 210 cannot be discharged or overflow outside the air conditioner.

[0058] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
