Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more specifically, to an evaporator connecting bracket, an indoor air conditioner unit, and an air conditioner. Background Technology

[0002] In existing technology, for the indoor unit of a cabinet air conditioner, the evaporator is generally supported and installed by an evaporator bracket. Typically, the evaporator bracket includes an upper evaporator bracket, an evaporator connecting bracket, and a lower evaporator bracket, with the connecting bracket located in the middle to connect the upper and lower brackets. Since the air outlet of the cabinet air conditioner's indoor unit is located within the evaporator connecting bracket, the cold air blown out by the air conditioner also lowers the temperature of the evaporator connecting bracket. When water vapor in the air encounters the cooler evaporator connecting bracket, it condenses on it. Excessive condensation can easily splash onto the outside of the drip tray, such as onto the chassis, causing mold and bacteria growth, thus affecting the normal operation of the air conditioner. Summary of the Invention

[0003] The first objective of this invention is to provide an evaporator connection bracket to solve the technical problem that existing condensation flows too fast on the vertical plate and easily splashes onto the outside of the water receiving tray, causing mold and bacteria to grow on components such as the chassis.

[0004] The evaporator connection bracket provided by the present invention includes a vertical plate and a water-guiding rib disposed on the vertical plate. The water-guiding rib extends along the width direction of the evaporator connection bracket, and the first end of the water-guiding rib is higher than the second end of the water-guiding rib, wherein the second end is the end of the water-guiding rib near the rear edge of the vertical plate.

[0005] The beneficial effects of the evaporator connecting bracket of the present invention are:

[0006] By incorporating water-guiding ribs, condensation can be generated on the outer surface of the vertical plate in the area above the ribs. As the condensation flows downwards along the outer surface of the vertical plate, it is prevented from continuing to flow directly downwards. Because the end of the water-guiding rib near the rear edge of the vertical plate is lower, the condensation is guided to the rear edge of the vertical plate, allowing it to flow downwards along that edge. This limits the path of the condensation flow, preventing it from falling over an excessive area and ensuring it enters a predetermined area. Simultaneously, it prevents the condensation from flowing continuously downwards at excessive speed, which could cause excessive kinetic energy and splashing onto the outside of the drip tray, such as onto the chassis. This prevents mold and bacteria growth on the chassis and other components, thus ensuring the normal operation of the air conditioner. Furthermore, the water-guiding ribs also reinforce the structure of the vertical plate, extending the service life of the evaporator connection bracket.

[0007] In the preferred embodiment, the angle between the water-guiding rib and the horizontal plane is greater than or equal to 5° and less than or equal to 60°.

[0008] Setting the angle described above not only stops the condensation from flowing directly downwards continuously, but also, due to the surface effect of water, prevents its downward velocity from being completely converted into flow velocity along the guide ribs. It may even temporarily accumulate at the corresponding positions on the guide ribs, allowing the water to flow down the ribs once a certain level has been reached. Furthermore, it conveniently guides the condensation flowing onto the guide ribs to the rear edge of the vertical plate, preventing excessive accumulation on the guide ribs and subsequent overflow onto the side of the plate away from the guide ribs, thus avoiding water splashing.

[0009] In a preferred embodiment, the number of water-guiding ribs is multiple, and the multiple water-guiding ribs are arranged at intervals along the vertical direction.

[0010] By arranging multiple water-guiding ribs vertically, each water-guiding rib intercepts condensation generated on the vertical plate within a small height range and a small area. This also prevents the condensation from accumulating a large velocity due to continuous flow over a long distance from its point of origin. This eliminates the possibility that the condensation, after flowing to the water-guiding rib, will not be guided by the water-guiding rib according to its tilt direction and will flow directly to the side of the water-guiding rib away from the vertical plate.

[0011] In a preferred embodiment, the side of the water-guiding rib facing away from the upright plate is higher than the side of the water-guiding rib connected to the upright plate, or the side of the water-guiding rib connected to the upright plate is at the same height.

[0012] By setting the height of the two sides of the water-guiding rib in this way, it is possible to prevent condensation from flowing to the water-guiding rib and then falling from the side away from the vertical plate, causing excessive speed and splashing of water droplets. Even if the two sides of the water-guiding rib are at the same height, because the second end of the water-guiding rib is lower than the first end, the condensation flows from the first end to the second end after reaching the water-guiding rib, and does not overflow the side away from the vertical plate.

[0013] In a preferred embodiment, the evaporator connecting bracket further includes a first folded edge, which is disposed on the rear edge of the upright plate. By providing a first folded edge on the rear edge of the upright plate, effective drainage of condensation can be achieved, allowing the condensation to flow further downwards along the first folded edge after being drained to the rear edge of the upright plate.

[0014] In a preferred embodiment, the first folded edge comprises multiple folded edge units arranged longitudinally, with vertical gaps between the multiple folded edge units, and the second end of the water-guiding rib is connected to the folded edge unit.

[0015] By designing multiple folded-edge segments with vertical gaps between them, the condensation doesn't flow continuously on the segments, allowing for sustained accumulation of velocity. Since the water flow from the condensation is limited, surface tension prevents it from dripping directly from the bottom of each segment. Instead, sufficient liquid accumulates until the surface tension is insufficient to balance its weight, causing the liquid to detach from the bottom and fall onto the next segment. Each time the liquid begins to drip from the bottom, the velocity increases from zero, ensuring a relatively low velocity in the lower segments. This prevents excessive splashing when the final drop reaches the bottom of the first fold.

[0016] In a preferred embodiment, the second end of the water-guiding rib is connected to the bottom end of the folded-edge unit.

[0017] Attaching the water-guiding ribs to the bottom of the folded edge unit reduces the distance water travels continuously along the folded edge unit after detaching from the ribs. Because the angle of the water-guiding ribs is small, their inclination effect is not significant relative to surface tension. Therefore, the condensation on the ribs flows at a low velocity, and naturally, the velocity when it reaches the folded edge unit is also low. Moreover, this velocity does not involve a long vertical acceleration along the folded edge unit. Consequently, when the condensation reaches the bottom of the folded edge unit, its ability to overcome the surface effect between the condensation and the folded edge unit is further reduced. It is difficult for the condensation to drip quickly directly from the bottom of the folded edge unit onto the folded edge unit below, causing the velocity to gradually accumulate until it reaches the bottom of the first folded edge at an excessively high velocity, resulting in splashing water droplets.

[0018] In a preferred embodiment, the evaporator connecting bracket further includes a second folded edge, which is disposed opposite to the first folded edge. A lower water guide plate is fixedly connected to the bottom of the second folded edge, and a water guide plate is fixedly connected to the lower water guide plate. The lower water guide plate gradually decreases from the end connected to the second folded edge to the end connected to the water guide plate.

[0019] The lower water inlet plate and the water inlet riser plate can guide the condensation generated in the area near the second fold edge of the riser plate to the front side of the water inlet riser plate through the lower water inlet plate, and leave it along the water inlet riser plate to prevent direct dripping and water splashing.

[0020] In a preferred embodiment, the top end of the lower water-diverting plate is connected to the second chamfered edge, and the bottom end of the lower water-diverting plate is connected to the chamfered edge of the water-diverting upright plate.

[0021] Connecting the top and bottom of the lower water inlet plate to the second fold and the chamfer of the water inlet plate respectively can improve the flow of water at both ends of the lower water inlet plate, thereby quickly guiding the water to the water receiving tray below.

[0022] The second objective of this invention is to provide an air conditioning indoor unit that solves the technical problem that condensation on the vertical plate flows too fast and easily splashes onto the outside of the drip tray, causing mold and bacteria to grow on the chassis and other components.

[0023] The air conditioner indoor unit provided by the present invention includes the above-mentioned evaporator connecting bracket.

[0024] By installing the aforementioned evaporator connection bracket in the indoor unit of the air conditioner, the indoor unit of the air conditioner has all the advantages of the aforementioned evaporator connection bracket, which will not be elaborated here.

[0025] The third objective of this invention is to provide an air conditioner that solves the technical problem that condensation on the vertical plate flows too fast and easily splashes onto the outside of the drip tray, causing mold and bacteria to grow on the chassis and other components.

[0026] The air conditioner provided by the present invention includes the above-mentioned indoor air conditioner unit.

[0027] By installing the aforementioned indoor unit in the air conditioner, the air conditioner will have all the advantages of the aforementioned indoor unit, which will not be elaborated here. Attached Figure Description

[0035] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0036] Example 1:

[0037] Figure 1 This is a schematic diagram of the structure of the evaporator support provided in an embodiment of the present invention; Figure 2 This is a schematic diagram of the evaporator support provided in an embodiment of the present invention, viewed from another direction. Figure 3 for Figure 2 A magnified view of part A. (See image below.) Figures 1-3 As shown, the evaporator connecting bracket provided in Embodiment 1 of the present invention includes a vertical plate 10 and a water-guiding rib 20 disposed on the vertical plate 10. The water-guiding rib 20 extends along the width direction of the evaporator connecting bracket, and the first end of the water-guiding rib 20 is higher than the second end of the water-guiding rib 20. The second end of the water-guiding rib 20 is the end of the water-guiding rib 20 that is close to the rear edge of the vertical plate 10.

[0038] The water-guiding ribs 20 are plate-shaped, and each rib 20 is preferably a flat plate. Using a flat plate shape simplifies processing and facilitates forming. Specifically, "flat plate" means that the water-guiding rib 20 itself is not curved, and is not parallel to the horizontal plane. Figures 1-3 In the diagram, the first end is the left end of the water-guiding rib 20, and the second end is the right end. Furthermore, those skilled in the art should understand that the connection between the water-guiding rib 20 and the vertical plate 10 should be continuous. No holes or gaps running vertically through the water-guiding rib 20 should be provided; otherwise, condensation will drip from the gaps or holes. Additionally, the rear edge of the vertical plate 20 refers to the edge of the vertical plate 20 closer to the air inlet of the indoor unit of the air conditioner.

[0039] By setting the water-guiding ribs 20, condensation can be generated on the outer surface of the vertical plate 10 in the area above the water-guiding ribs 20. As the condensation flows downward along the outer surface of the vertical plate 10, it prevents the condensation droplets from continuing to flow directly downward. Since the end of the water-guiding ribs 20 near the rear edge of the vertical plate 10 is lower, it can guide the condensation to the rear edge of the vertical plate 10, allowing the condensation to flow downward along the rear edge of the vertical plate 10. This limits the path of the condensation flow, preventing it from falling over a large area, and thus allowing the condensation to enter the preset area. At the same time, it prevents the condensation from flowing directly downward continuously at too high a speed, resulting in excessive kinetic energy and splashing outside the water receiving tray, such as onto the chassis, thereby preventing mold and bacteria growth on the chassis and other components, and ensuring the normal operation of the air conditioner. In addition, the water-guiding ribs 20 can also strengthen the structure of the vertical plate 10, thereby extending the service life of the evaporator connecting bracket.

[0040] like Figures 1-3 As shown, preferably, the angle between the water-guiding rib 20 and the horizontal plane is greater than or equal to 5° and less than or equal to 60°.

[0041] Setting the aforementioned angle not only prevents condensation from flowing directly downwards continuously, but also, due to the surface effect of water, its downward velocity will not be completely converted into a flow velocity along the water-guiding rib 20. It may even temporarily accumulate at the corresponding position of the water-guiding rib 20. After the water accumulates to a certain extent, it will then flow along the water-guiding rib 20. Moreover, it can conveniently guide the condensation flowing onto the water-guiding rib 20 to the first folded edge 30, preventing excessive accumulation of condensation on the water-guiding rib 20 and causing it to overflow and drip directly downwards onto the side of the water-guiding rib 20 away from the vertical plate 10, resulting in water splashing.

[0042] like Figures 1-2 As shown, preferably, there are multiple water-guiding ribs 20, and the multiple water-guiding ribs 20 are arranged at intervals along the vertical direction.

[0043] By vertically arranging multiple water-guiding ribs 20, each water-guiding rib 20 intercepts condensation generated on the vertical plate 10 within a small height range and a small area. This also prevents the condensation from accumulating a large velocity due to continuous flow over a long distance from its point of origin, thus eliminating the possibility that the condensation, after flowing to the water-guiding rib 20, will not be guided by the water-guiding rib 20 according to its tilt direction and will flow directly to the side of the water-guiding rib 20 away from the vertical plate 10.

[0044] like Figures 1-3 As shown, preferably, the side of the water-guiding rib 20 away from the vertical plate 10 is higher than the side of the water-guiding rib 20 connected to the vertical plate 10, or the side of the water-guiding rib 20 connected to the vertical plate 10 is at the same height.

[0045] By setting the relative height of the two sides of the water-guiding rib 20 in this way, it is possible to prevent condensation from flowing to the water-guiding rib 20 and then falling from the side of the water-guiding rib 20 away from the vertical plate 10, causing excessive speed and splashing of water droplets. Even if the two sides of the water-guiding rib 20 are at the same height, because the second end of the water-guiding rib 20 is lower than the first end, the condensation flowing to the water-guiding rib 20 will flow along the direction from the first end to the second end, and will not overflow the side away from the vertical plate 10.

[0046] like Figure 1 and Figure 3 As shown, the evaporator connecting bracket also includes a first folded edge 30, which is disposed on the rear edge of the vertical plate 10. By providing the first folded edge 30 on the rear edge of the vertical plate 10, effective drainage of condensation can be achieved, allowing the condensation to flow further downward along the first folded edge 30 after being guided to the rear edge of the vertical plate 10.

[0047] like Figures 1-3 As shown, preferably, the first folded edge 30 includes multiple folded edge units 31 arranged longitudinally, with vertical gaps left in the multiple folded edge units 31, and the second end of the water-guiding rib 20 is connected to the folded edge unit 31.

[0048] In this embodiment, each water-guiding rib 20 is connected to a folded edge unit 31. However, because a connecting structure is provided between some adjacent folded edge units 31 to fix the indoor unit connection bracket, water-guiding ribs 20 are not provided. Specifically, the height of the water-guiding rib 20 protruding from the vertical plate 10 is less than the height of the first folded edge 30 protruding from the vertical plate 10, so as to facilitate water flowing from the bottom end of the upper folded edge unit 31 to the top end of the lower folded edge unit 31. The vertical gaps in the multiple folded edge units 31 are... Figure 3 It can be seen quite clearly in the middle.

[0049] By setting multiple folded-edge units 31 with vertical gaps between them, the condensation does not flow continuously on the folded-edge units 31, allowing the velocity to accumulate continuously. Since the water flow generated by the condensation cannot be very large, due to surface tension, the water does not drip directly from the bottom of each folded-edge unit 31. Instead, when enough liquid has accumulated, the surface tension is insufficient to balance the weight of this liquid, causing it to detach from the bottom of the folded-edge unit 31 and fall onto the next folded-edge unit 31. Each time the liquid begins to drip from the bottom of the folded-edge unit 31, the velocity increases from zero. Therefore, the velocity during the flow on the next folded-edge unit 31 will not be very high, thus preventing excessively high velocity at the bottom of the first folded edge 30, which would cause splashing.

[0050] like Figures 1-3 As shown, preferably, the second end of the water-guiding rib 20 is connected to the bottom end of the folded-edge unit 31.

[0051] Connecting the water-guiding rib 20 to the bottom end of the folded unit 31 reduces the distance the water travels continuously on the folded unit 31 after detaching from the water-guiding rib 20. Because the angle of the water-guiding rib 20 is small, its tilting effect is not significant relative to surface tension. Therefore, the flow velocity of condensation on the water-guiding rib 20 is low, and its velocity when flowing to the folded unit 31 is also low. Moreover, this velocity does not involve a long vertical acceleration along the folded unit 31. Consequently, when the condensation reaches the bottom end of the folded unit 31, its ability to overcome the surface effect between the condensation and the folded unit 31 is further reduced. It is difficult for the condensation to drip quickly directly from the bottom end of the folded unit 31 onto the lower folded unit 31, causing the velocity to gradually accumulate until it reaches the bottom end of the first folded unit 30 at an excessively high velocity, resulting in water droplet splashing.

[0052] like Figures 1-2 and Figure 4 As shown, preferably, the evaporator connecting bracket further includes a second folded edge 40, which is arranged opposite to the first folded edge 30. The bottom of the second folded edge 40 is fixedly connected to a lower water inlet plate 50, and the lower water inlet plate 50 is fixedly connected to a water inlet upright plate 60. The lower water inlet plate 50 gradually decreases from the end connected to the second folded edge 40 to the end connected to the water inlet upright plate 60.

[0053] By setting up a lower water guide plate 50 and a water guide vertical plate 60, the condensation generated in the area of ​​the vertical plate 10 near the second fold edge 40 can be guided by the lower water guide plate 50 to the front side of the water guide vertical plate 60 and left along the water guide vertical plate 60 to prevent direct dripping and water splashing.

[0054] like Figures 1-2 and Figure 4 As shown, preferably, the top end of the lower water inlet plate 50 is chamfered and connected to the second folded edge 40, and the bottom end of the lower water inlet plate 50 is chamfered and connected to the water inlet upright plate 60.

[0055] By connecting the top and bottom ends of the lower water inlet plate 50 to the second folded edge 40 and the water inlet vertical plate 60 with chamfers, the flow of water at both ends of the lower water inlet plate 50 can be improved, thereby quickly guiding the water to the water receiving tray below.
