Description

Technical Field

[0001] The present invention belongs to the technical field of air conditioning, and in particular relates to a drainage device and an air conditioner having the same. Background Art

[0002] At present, mobile air conditioners on the market generally have three drainage methods to adapt to different usage environments: 1. Bottom drainage (usually called bottom manual drainage), which is suitable for environments with low humidity. Water is stored in the chassis and atomized, and the condenser is cooled using the condensed water to achieve the purpose of reusing the condensed water and improving the cooling effect and energy efficiency. When the water volume reaches the full water protection level or the machine is not used for a long time, the water in the chassis or water tank needs to be drained manually. When draining, the drain plug or drain cover at the bottom drain nozzle needs to be opened, and then the drain pipe is connected to achieve drainage; 2. Intermediate drainage (usually called intermediate continuous drainage). In low humidity environments, the drain plug and drain cover are installed to allow the condensed water to flow into the chassis inside the machine for secondary use and cooling. In high humidity, manually open the drain plug and drain cover, connect the drain pipe, and directly drain the condensed water outside the machine to avoid frequent water full protection and ensure continuous operation of the machine; 3. Water pump drainage (usually called automatic drainage) is suitable for long-term unattended machines or environments and conditions where water needs to be drained to a higher place. When draining, open the drain plug or drain cover at the drain nozzle of the water pump, and then connect the drain pipe to drain. The above three drainage methods can be found in Figure 16 .

[0003] From an economic and environmental perspective, intermediate drainage is a crucial feature for mobile air conditioners. It allows condensed water to drain into the chassis to improve cooling efficiency in low-humidity environments, while also draining it externally in high-humidity environments. However, the current intermediate drainage feature requires manual switching between internal and external drainage, which can lead to missed or delayed switching. Therefore, a simple, automated switching solution is urgently needed. Summary of the Invention

[0012] In some embodiments, the diameter of the rotating shaft is D3, the diameter of the through hole is D4, and D4+0.5mm>D3>D4+0.1mm.

[0013] In some embodiments, the first matching groove is a strip-shaped groove with a constant width, and the width of the first matching groove is L1, 1 / 3D4>L1>0.8mm.

[0041] See also Figures 1 to 16As shown, according to an embodiment of the present invention, a drainage device is provided, including: a drainage structure, the drainage structure having a drainage groove, the drainage structure also having a first drain port 1 and a second drain port 2 respectively connected to the drainage groove, a temporary storage mechanism is arranged below the drainage structure, the temporary storage mechanism includes a rotatable shell 5, the shell 5 has a rotation axis, a water collection tank is formed inside the shell 5, with the rotation axis as the boundary, the part of the water collection tank on the first side of the rotation axis is the first area, and the part of the water collection tank on the second side of the rotation axis is the second area, the shell 5 also has a third drain port 3 connected to the first area and a fourth drain port 4 connected to the second area, the shell 5 has a horizontal state and an inclined state, when the shell 5 is in the horizontal state, the first drain port 1 corresponds to the position of the third drain port 3, and the second drain port 2 corresponds to the position of the second area, when the shell 5 is in the inclined state, the first area is higher than the second area, and the first drain port 1 and the third drain port 3 are staggered, and the second drain port 2 corresponds to the position of the second area. In this technical solution, when the drainage device of the present application is applied to the air conditioner and is located below the evaporator 20, if the ambient humidity is low, the evaporator 20 generates less condensed water, and the amount of condensed water dripping from the evaporator 20 into the drainage groove of the drainage structure is less, then the shell 5 can be controlled to be in a horizontal state, and a small amount of condensed water will be discharged from the first drain port 1 and the second drain port 2 respectively. The condensed water discharged from the first drain port 1 enters the interior of the air conditioner through the third drain port 3 of the shell 5, and is atomized by the water pumping mechanism to condense the condenser 21, thereby improving the heat exchange effect of the condenser; the condensed water discharged from the second drain port 2 is discharged to the outside of the air conditioner through the fourth drain port 4 of the shell 5. If the ambient humidity is high, the evaporator 20 generates a lot of condensed water, and a lot of condensed water drips from the evaporator 20 into the drainage groove. The housing 5 can be controlled to be in a tilted state, and a large amount of condensed water is discharged from the first drain port 1 and the second drain port 2. However, due to the tilt of the housing 5, the first drain port 1 and the third drain port 3 are misaligned, so the condensed water discharged from the first drain port 1 and the second drain port 2 will be discharged to the outside of the air conditioner through the fourth drain port 4. Therefore, the drainage device of the present application can automatically drain water to the inside of the air conditioner when the humidity is low, and automatically drain water to the outside of the air conditioner when the humidity is high, thereby solving the problem that when the existing mobile air conditioner adopts intermediate drainage, the conversion between draining water to the inside of the machine and draining water to the outside of the machine is completed by manual operation, and there is a problem of missing conversion or untimely conversion. Among them, the drainage structure is equivalent to a water receiving tray.

[0042] Specifically, the cross-sectional area of ​​the third drain port 3 is larger than that of the fourth drain port 4. When the humidity is low, the condensed water dripping from the evaporator 20 into the drainage groove is small. The condensed water discharged from the first drain port 1 enters the interior of the air conditioner through the third drain port 3 of the shell 5, and the condensed water discharged from the second drain port 2 is discharged to the outside of the air conditioner through the fourth drain port 4 of the shell 5. Because the condensed water is small, the drainage speed of the third drain port 3 and the fourth drain port 4 is the same, so that the two sides of the shell 5 are in a balanced state, which can ensure that the shell 5 is automatically in a horizontal state. Figure 2 When the humidity is high, a lot of condensed water drips from the evaporator 20 into the drainage groove, and a large amount of condensed water is discharged from the first drain port 1 and the second drain port 2. When the water flow rate in the shell 5 is greater than the drainage rate of the fourth drain port 4, because the cross-sectional area of ​​the third drain port 3 is larger than the cross-sectional area of ​​the fourth drain port 4, more water accumulates in the second area where the fourth drain port 4 is located. That is, the side of the shell 5 where the second area is located is heavier than the side where the first area is located. Therefore, the shell 5 automatically tilts toward the side where the second area is located. The third drain port 3 is offset from the first drain port 1, and the condensed water discharged into the shell 5 from the first drain port 1 will also be discharged from the fourth drain port 4. Figure 1 When the water is drained to the outside of the air conditioner through the fourth drain port 4 and the surrounding environment returns to low humidity, and the condensed water generated by the evaporator 20 is less, the housing 5 returns to its initial horizontal state under the action of gravity, as shown in FIG. Figure 4 shown.

[0043] See also Figure 7 As shown, the inner diameter of the fourth drain port 4 is D1, 6mm>D1>3.5mm. This size ensures normal drainage from the fourth drain port 4. The inner diameter of the third drain port 3 is D2, D2 = 1.8D1, so that the third drain port 3 and the fourth drain port 4 are within a reasonable ratio range, thereby achieving a better cooling effect and less frequent condensation protection when the air conditioner is in an efficient state. Condensation protection is to drain condensed water outside the air conditioner when the humidity is high.

[0044] Preferably, a retaining structure 6 is provided at the third drain outlet 3. The retaining structure 6 extends from the third drain outlet 3 to the first drain outlet 1. The retaining structure 6 has a flow passage. The first end of the flow passage is connected to the third drain outlet 3. When the shell 5 is in a horizontal state, the second end of the flow passage corresponds to the first drain outlet 1. When the shell 5 is in an inclined state, the second end of the flow passage is offset from the first drain outlet 1. Since the retaining structure 6 has a certain height, when the shell 5 is inclined at the same angle, the second end of the retaining structure 6 is displaced more horizontally relative to the third drain outlet 3, causing the first drain outlet 1 and the third drain outlet 3 to be displaced more quickly, ensuring a more timely switch from draining water to the inside of the air conditioner to draining water to the outside of the air conditioner.

[0045] See also Figure 5 As shown, the enclosure structure 6 includes an arc-shaped side wall, and a peripheral edge 7 is provided in the first area. The peripheral edge 7 and the arc-shaped side wall are enclosed to form a water receiving trough, and the third drain port 3 is connected to the water receiving trough. A small amount of condensed water can be temporarily stored in the water receiving trough. This part of the water will increase the weight of the first area in the shell 5, which is conducive to the shell 5 automatically recovering from an inclined state to a horizontal state. During the processing of the shell 5, the two longer side walls of the shell 5 are prone to sink inward and deform. In order to improve this situation, two support bars are further provided in the shell 5. One end of the two support bars is respectively connected to the two long side walls of the shell 5, and the other end is connected to the peripheral edge 7. The height of the support bar is H1, 6mm>H1>3.5mm, which provides support and prevents deformation while reducing consumables. The height of the surround 7 is H2, the height of the shell is H3, the height of the curved side wall is H4, 0.5H4>H2>1.5H1, 0.5H4>H3>1.8H1; the width of the shell is L5, the width of the water trough is L6, 0.8L5>L6>0.5L5. By constraining the sizes of these components, the air conditioner can achieve the best cooling effect and the least condensation water protection frequency in an effective state.

[0046] See also Figure 4 and Figure 5 As shown, the temporary storage mechanism also includes a rotating shaft 8, which is connected to the shell 5. The central axis of the rotating shaft 8 is a rotation axis. The drainage structure also has a mounting portion 9, and a through hole 10 is constructed on the mounting portion 9. The through hole 10 runs through the thickness direction of the mounting portion 9. The rotating shaft 8 can be rotatably inserted into the through hole 10 to enable the shell 5 to rotate.

[0047] Specifically, mounting portion 9 is further configured with two first mating grooves 11, which also extend through the thickness of mounting portion 9. Both first mating grooves 11 communicate with through-hole 10 and are symmetrically positioned about the central axis of through-hole 10. Rotating shaft 8 forms an interference fit with through-hole 10. The combination of through-hole 10 and the two first mating grooves 11 allows rotating shaft 8 to rotate while providing a certain degree of damping, preventing errors when housing 5 switches between horizontal and tilted positions.

[0048] See also Figure 7 and Figure 10 As shown, the diameter of the rotating shaft 8 is D3, the diameter of the through hole 10 is D4, D4+0.5mm>D3>D4+0.1mm; the first matching groove 11 is a strip groove with a constant width, and the width of the first matching groove 11 is L1, 1 / 3D4>L1>0.8mm, so that the through hole 10 produces a better damping effect on the rotating shaft 8, but does not affect the rotation of the rotating shaft 8.

[0049] See also Figure 10As shown, the mounting portion 9 is also constructed with two second mating grooves 12. The second mating grooves 12 also extend through the thickness of the mounting portion 9. The two second mating grooves 12 are located above and below the through hole 10, respectively, and are symmetrical with respect to the central axis of the through hole 10. The second mating groove 12 includes an arc segment and a strip segment connecting the two sides of the arc segment. The arc segment corresponds to the position of the through hole 10 and has the same curvature as the through hole 10. The strip segment corresponds to the position of the first mating groove 11 and is parallel to the through hole 10. The vertical distance between the strip segment and the first mating groove 11 is L2, where 2mm>L2>0.8mm. This ensures that the periphery of the through hole 10 has a certain strength while also having a certain elastic deformation capacity, further ensuring that the through hole 10 produces an excellent damping effect on the rotating shaft 8 without affecting the rotation of the rotating shaft 8.

[0050] See also Figure 6 As shown, the portion of the sump within the first region has a first sidewall, and the portion of the sump within the second region has a second sidewall. The first and second sidewalls face each other and are located on opposite sides of the central axis. The maximum distance between the central axis and the first sidewall is L3, and the maximum distance between the central axis and the second sidewall is L4, where 2L3>L4>1.2L3. Because the first region of the housing 5 includes curved sidewalls and a peripheral edge 7, the housing 5 is left-heavy and right-light. When 2L3>L4>1.2L3, the housing 5 is balanced on both sides, bounded by the central axis of the rotating shaft 8.

[0051] See also Figures 1 to 4 As shown, a drainage structure is provided below the temporary storage mechanism. The drainage structure has a first water storage tank 13 and a second water storage tank 14, which are independent of each other. The drainage structure also has a fifth drain port 15 connected to the first water storage tank 13 and a sixth drain port 16 connected to the second water storage tank 14. The third drain port 3 corresponds to the position of the first water storage tank 13, and the fourth drain port 4 corresponds to the position of the second water storage tank 14. The fifth drain port 15 can be connected to the condenser 21, and the sixth drain port 16 can be connected to the intermediate drain pipe 26. The arrangement of the drainage structure further facilitates the discharge of condensed water into and outside the air conditioner.

[0052] See also Figure 12 As shown, the first water storage tank 13 and the second water storage tank 14 have a common side wall, on which a notch 17 is formed. The notch 17 can prevent the problem of uncontrolled condensed water flow after the middle drain pipe 26 is blocked.

[0053] Specifically, a partition plate 18 is provided in the drainage trough, which divides the drainage trough into two identical and independent drainage channels 19. The first drain outlet 1 is connected to one of the drainage channels 19, and the second drain outlet 2 is connected to the other drainage channel 19, ensuring that the drainage speed of the first drain outlet 1 and the second drain outlet 2 is the same.

[0054] The present invention further provides an air conditioner, comprising the above-mentioned drainage device, and the air conditioner herein particularly relates to a mobile air conditioner.

[0055] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

The above are merely preferred embodiments of the present invention.
