Abstract
Description
Technical Field
[0001] This application belongs to the field of air conditioning technology, and in particular relates to a leak-proof structure for a built-in air conditioner and the air conditioner itself. Background Technology
[0002] Currently, in vehicles with built-in split air conditioning systems, the evaporator core produces a large amount of condensate during cooling and dehumidification. Under the influence of gravity, the condensate flows along the fins into the water collection tray. When the water in the collection tray accumulates to a certain level, the water will flow out through the drain outlets at both ends of the collection tray and then flow to the outside of the vehicle through the drain hose.
[0003] In existing technology, a coarse-pore sponge is usually laid inside the water collection pan to absorb condensate and prevent the water stored in the water collection pan from being thrown out when the vehicle is suddenly driven or stopped or when the road conditions are bumpy. However, under this design, the coarse-pore sponge is prone to getting dirty after use, which prevents the condensate from flowing smoothly to the drain outlets at both ends. When there is too much water, water splashes in the water collection pan are easy to splash near the opening. The water splashes in this area can easily be sucked into the high-speed fan, causing the air conditioner to leak. Utility Model Content

[0042] The technical solution of this application will now be described in detail with reference to the accompanying drawings and embodiments.
[0043] This embodiment provides a leak-proof structure for a built-in air conditioner, such as... Figures 1-4 As shown, it includes: a water collection tray 1, a support plate 3, and a water absorption plate 6.
[0044] A water collection tray 1 is provided below the core 2 of the air conditioner. The water collection tray 1 has a cavity 10 for containing condensate. The cavity 10 has an opening 13 on its upper side for the condensate to enter. The bottom of both ends of the water collection tray 1 along the X direction has a drain outlet 121 for water to flow out.
[0045] Several support plates 3 are spaced apart along the X-direction within the cavity 10. The support plates 3 are connected to the inner wall of the water collection tray 1, and the height of the support plates 3 in the vertical direction (Z-direction) is higher than the highest point of the drain outlet 121. Because the support plates 3 are spaced apart along the X-direction, the upper space of the cavity 10 is not completely sealed, so the support plates 3 do not significantly reduce the water storage capacity of the water collection tray 1. The absorbent plate 6 is laid on the support surface composed of several support plates 3. The function of the absorbent plate 6 is to absorb water, thereby reducing water splashing in the water collection tray 1 by absorbing water into its internal pores.
[0046] This embodiment also provides an air conditioner, such as Figure 3 As shown, the water-proof structure of the built-in air conditioner also includes: a core 2 and a fan 5. The core 2 is located above the water-proof structure of the built-in air conditioner; the fan 5 is located on one side of the water-proof structure of the built-in air conditioner along the Y direction.
[0047] The water-proof structure and air conditioner of the built-in air conditioner in this embodiment are achieved by arranging several support plates 3 at intervals along the X direction within the cavity 10, providing the support surface required for laying the water-absorbing plate 6. The vertical height of the support plates 3 and the water-absorbing plate 6 is higher than the highest point of the drain outlet 121, preventing the water-absorbing plate 6 from obstructing the discharge of water accumulated in the water collection tray 1 and preventing excessive water from overflowing and being sucked into the fan 5. Thus, this utility model can significantly improve the problem of air conditioner water leakage under certain conditions.
[0048] In an alternative embodiment, such as Figure 2 As shown, the inner wall of the water collection tray 1 extends at least partially from both sides towards the center in a downward (Z-direction downward) direction, which can concentrate the condensate collected in the cavity 10 towards the center, reduce the amount of water stored at the edge of the water collection tray 1, and reduce the probability of water splashing out of the cavity 10, thereby reducing the probability of water being sucked into the fan 5. Furthermore, this inner wall structure also facilitates the collection of water flow to the lowest point, and placing the drain outlet 121 at the center of the bottom of the water collection tray 1 can significantly improve the drainage effect.
[0049] In an alternative embodiment, such as Figure 2As shown, the water collection tray 1 includes an upper part 11 and a lower part 12. The inner wall of the lower part 12 extends from both sides in the Y direction from top to bottom towards the middle. The upper part 11 is connected to the upper side of the lower part 12, and the side wall of the upper part 11 extends vertically. In this embodiment, the upper and lower parts of the water collection tray 1 are designed with distinct shapes. The inner wall of the lower part 12 extends from both sides in the Y direction from top to bottom towards the middle. Its function is to gather the condensate collected in the cavity 10 towards the middle, reducing the amount of water stored at the edge of the water collection tray 1, and also facilitating the water flow to be gathered at the lowest point, thus improving the drainage effect. The side wall of the upper part 11 extends vertically, making the volume of the upper part 11 larger, which is beneficial to increasing the overall water storage capacity of the water collection tray 1.
[0050] In an alternative embodiment, such as Figure 2 As shown, the water-absorbing plate 6 is located at the bottom of the upper half 11. In this embodiment, arranging the water-absorbing plate 6 at the bottom of the upper half 11 does not occupy the space of the lower half 12, thus avoiding affecting the water flow collection effect of the lower half 12. At the same time, it absorbs the water exceeding the capacity of the lower half 12. After the water in the lower half 12 is discharged, the water droplets in the water-absorbing plate 6 gradually flow to the lower half 12.
[0051] In an alternative embodiment, such as Figure 2 As shown, the two ends of the support plate 3 along the Y direction are attached to and fixed to the inner wall of the water collection tray 1; both the Y and X directions are horizontal, and the Y direction is perpendicular to the X direction, which can improve the stability of the connection between the isolation plate 3 and the water collection tray 1.
[0052] In an alternative embodiment, such as Figures 1-3 As shown, the leak-proof structure of the built-in air conditioner in this embodiment also includes a baffle 4. The baffle 4 is fixed to one edge of the opening 13 along the Y direction. The baffle 4 extends at least partially into the water collection tray 1 in a direction inclined relative to the vertical direction. Both the Y and X directions are horizontal, and the Y direction is perpendicular to the X direction. It can be understood that the baffle 4 can also be fixed to both sides of the opening 13 along the Y direction to increase the effective range.
[0053] like Figure 5 As shown, the function of the baffle 4 is to guide the water flow that tends to rush out of the water collection tray 1, and to guide the water splashed at the edge of the opening 13 of the water collection tray 1 back into the cavity 10, so as to prevent the water splashed out and being sucked in by the fan 5. This can significantly improve the air conditioning water leakage problem caused by water splashing at the edge of the opening 13 of the water collection tray 1 when the vehicle is bumpy.
[0054] In an alternative embodiment, such as Figure 5 , Figure 6 As shown, the baffle 4 located on the side of the air inlet of the fan 5 near the air conditioner in the opening 13 includes: a first shielding surface 41 and a second shielding surface 42.
[0055] The first shielding surface 41 is fixed to the edge of the opening 13, and extends inward toward the water collection tray 1 in a direction inclined relative to the vertical direction (Z direction); the second shielding surface 42 is fixed to the upper edge of the first shielding surface 41, and extends outward toward the water collection tray 1 in a direction inclined relative to the vertical direction (Z direction). In this embodiment, as... Figure 5 As shown, firstly, water flowing along the Y direction in the cavity 10 and about to overflow the edge of the water collection tray 1 flows back to the center of the cavity 10 under the action of the first shielding surface 41. Secondly, condensate water falling from the core 2 under the suction of the fan 5 can fall onto the second shielding surface 42. Since the second shielding surface 42 has a certain inclination, the water can flow back into the cavity 10 along its surface. Therefore, the baffle 4 provided in this embodiment can improve the phenomenon of water leakage from the air conditioning fan in at least two aspects.
[0056] In an alternative embodiment, such as Figure 6 As shown, the baffle 4 is a V-shaped plate, with the corner of the plate dividing it into the first shielding surface 41 and the second shielding surface 42. In this embodiment, the baffle 4 is made of a V-shaped plate, which has a simple structure, low cost, and helps to reduce equipment costs.
[0057] In an alternative embodiment, such as Figure 6 As shown, the connection between the first shielding surface 41 and the water collection tray 1 is a first arc-shaped transition surface 411; the connection between the second shielding surface 42 and the upper edge of the first shielding surface 41 is a second arc-shaped transition surface 421. In this embodiment, the first arc-shaped transition surface 411 can promote a smooth change in water flow direction and reduce water splashing. The second arc-shaped transition surface 421 can guide the water flow down the upper surface of the second shielding surface 42, making it easier for water droplets to flow downwards rather than in the X direction, reducing the probability that the collected water droplets are not properly recovered into the cavity 10.
[0058] In an optional embodiment, the absorbent plate 6 is made of materials such as sponge, superabsorbent polymer (SAP), porous ceramic, or foam plastic.
[0059] Based on the above-described preferred embodiments according to this application, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this application. The technical scope of this application is not limited to the contents of the specification, but must be determined according to the scope of the claims.
