Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning drainage, in particular to a drainage structure. Background Art

[0002] Due to the convenience of mobile air conditioners, the popularity of mobile air conditioners is increasing nowadays.

[0003] The refrigeration process of the mobile air conditioner is mainly achieved by the internal evaporator. However, during the refrigeration process of the mobile air conditioner, condensed water will condense on the surface of the evaporator, and the generated condensed water needs to be drained to the outside.

[0004] For example, an air conditioning drainage structure and a mobile air conditioner disclosed in publication number CN117029255A. The condensed water generated by the existing mobile air conditioner is generally received by the water receiving tray below the evaporator and falls into the condenser below through the drainage holes on the water receiving tray, and is discharged to the outside through evaporation of the condenser.

[0005] However, there is only one drainage hole on the existing water receiving tray. When an abnormal situation occurs and the drainage hole is blocked and the water cannot be drained or the drainage is not smooth, the water level in the water receiving tray will rise and eventually overflow from the water receiving tray, causing poor drainage and even damage to other components inside the mobile air conditioner, thereby causing safety hazards.

[0006] With respect to the above-mentioned related technologies, there is a problem that the existing drainage structure of the water receiving pan cannot cope with the situation of poor drainage caused by abnormal conditions. Utility Model Content

[0007] In view of the above-mentioned deficiencies in the prior art, an object of the present invention is to provide a drainage structure, aiming to solve the problem that the drainage structure of the existing water receiving tray cannot cope with the situation of poor drainage caused by abnormal conditions.

[0008] A drainage structure provided in the present application adopts the following technical solution: a drainage structure, comprising:

[0009] Water tray body;

[0010] A drainage column, arranged on the water receiving tray body;

[0011] There are at least two drainage columns, each of which is provided with drainage holes, and the drainage holes on different drainage columns are staggered in the vertical direction, and the drainage holes connect the drainage column and the water receiving tray body.

[0012] Optionally, a first water storage tank is provided on the water receiving tray body, and the plurality of drainage columns are all arranged in the first water storage tank.

[0013] Optionally, the height of the plurality of drainage holes is lower than the height of the opening position of the first water storage tank.

[0014] Optionally, a centralized drainage area is provided on the bottom of the first water storage tank, a plurality of drainage columns are provided in the centralized drainage area, the bottom of the first water storage tank is inclined, and the centralized drainage area is located at the lowest point of the bottom of the first water storage tank.

[0015] Optionally, the centralized drainage area is arranged in the middle position of the first water storage tank.

[0016] Optionally, an overflow baffle is provided at the bottom of the first water storage tank, and the overflow baffle is used to guide water flow to the drainage column.

[0017] Optionally, a water collection tank is provided in the centralized drainage area, and the plurality of drainage columns are all provided in the water collection tank;

[0018] The flow baffle is used to guide water flow into the water collecting tank.

[0019] Optionally, an emergency drain pipe is provided on the water receiving tray body, and the emergency drain pipe is connected to the first water storage tank;

[0020] The emergency drain pipe is detachably connected with a blocking cover.

[0021] Optionally, a second water storage tank is provided at the bottom of the water collection tank, and the second water storage tank is connected to the emergency drain pipe.

[0022] Optionally, the bottom of the water collecting trough is inclined, and the second water storage tank is located at the lowest point of the water collecting trough.

[0023] Compared with the prior art, the embodiment of the utility model has the following advantages:

[0024] The evaporator is arranged on the water receiving pan body, so that the condensed water generated by the evaporator condensation will fall onto the water receiving pan body. The condensed water falling on the water receiving pan body will eventually fall onto the condenser under the water receiving pan body through the drainage hole, and finally be discharged to the outside under the evaporation action of the condenser.

[0025] Under normal circumstances, the condensed water can smoothly flow into the condenser below for discharge through the drainage hole on the drainage column with the smallest distance from the drainage hole to the water tray body.

[0026] When an abnormal situation occurs and the drain hole on the drain column with the smallest distance to the water receiving pan body becomes blocked or drainage is poor, the water level of the condensed water in the water receiving pan body will rise until the water level reaches the position of the drain hole set on the next drain column. The distance from the drain hole on this drain column to the water receiving pan body is only higher than the distance from the drain hole on the blocked drain column to the water receiving pan body. Finally, the condensed water is discharged from the drain hole on the drain column.

[0027] If the drainage hole of this drainage column is also blocked, the drainage will be carried out through the drainage hole on the next drainage column. The distance from the drainage hole on this drainage column to the water receiving tray body is only higher than the distance from the drainage holes of the first two drainage columns to the water receiving tray body, until the liquid can be discharged smoothly.

[0028] By setting up multiple drainage columns of different heights, condensed water can be smoothly discharged from the water tray body, ensuring the normal operation of the mobile air conditioner drainage system, increasing the safety of the product, and solving the problem that the drainage structure of the existing water tray cannot cope with poor drainage caused by abnormal conditions.

DETAILED DESCRIPTION

[0035] In order to enable those skilled in the art to better understand the solution of the utility model, the following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] The present application is further described in detail below in conjunction with the accompanying drawings.

[0037] An embodiment of the present application discloses a drainage structure.

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, a drainage structure includes a water receiving tray body 1 and a drainage column 2. The drainage column 2 is arranged on the water receiving tray body 1; wherein, at least two drainage columns 2 are arranged, drainage holes are arranged on the drainage columns 2, and the drainage holes on different drainage columns 2 are staggered in the vertical direction, and the drainage holes connect the drainage columns 2 and the water receiving tray body 1.

[0039] The evaporator is arranged on the water receiving pan body 1, so that the condensed water generated by the evaporator condensation will fall onto the water receiving pan body 1. The condensed water falling onto the water receiving pan body 1 will eventually fall onto the condenser below the water receiving pan body 1 through the drainage hole, and will eventually be discharged to the outside under the evaporation action of the condenser.

[0040] Under normal circumstances, the condensed water can smoothly flow into the condenser below and be discharged simply by passing through the drainage hole on the drainage column 2 where the distance from the drainage hole to the water receiving tray body 1 is the smallest.

[0041] When an abnormal situation occurs and causes the drain hole on the drain column 2 with the smallest distance to the water receiving pan body 1 to be blocked or drainage is poor, the water level of the condensed water in the water receiving pan body 1 will rise until the water level reaches the position of the drain hole set on the next drain column 2. The distance from the drain hole on this drain column 2 to the water receiving pan body 1 is only higher than the distance from the drain hole on the blocked drain column 2 to the water receiving pan body 1. Finally, the condensed water is discharged from the drain hole on the drain column 2.

[0042] If the drainage hole of this drainage column 2 is also blocked, the drainage will be carried out through the drainage hole on the next drainage column 2 by analogy. The distance between the drainage hole on this drainage column 2 and the water receiving tray body 1 is only higher than the distance between the drainage holes of the first two drainage columns 2 and the water receiving tray body 1, until the liquid can be discharged smoothly.

[0043] By setting up multiple drainage columns 2 with different heights, condensed water can be smoothly discharged from the water receiving tray body 1, ensuring the normal operation of the mobile air conditioning drainage system, increasing the safety of the product, and solving the problem that the drainage structure of the existing water receiving tray cannot cope with the poor drainage caused by abnormal conditions.

[0044] A first water storage tank 11 is disposed on the water receiving tray body 1 , and a plurality of drainage columns 2 are disposed in the first water storage tank 11 .

[0045] Specifically, the drainage holes are arranged at the ends of the drainage columns 2, and the heights of the plurality of drainage columns 2 are different.

[0046] The shape of the water receiving pan body 1 is generally rectangular, and the shape of the first water storage tank 11 is similar to that of the water receiving pan body 1 and is also rectangular. The first water storage tank 11 is arranged on the top surface of the water receiving pan body 1. The evaporator of the mobile air conditioner is generally directly installed in the first water storage tank 11, and the size of the first water storage tank 11 matches the evaporator. After the evaporator condenses the condensed water, it will directly drip into the first water storage tank 11 for storage, thereby preventing the condensed water from falling on other parts of the mobile air conditioner and causing damage to other parts in the mobile air conditioner.

[0047] In this embodiment, two drain columns 2 are provided, namely a first drain column 212 and a second drain column 222. The drainage hole on the first drain column 212 is the first drain hole 211, and the drainage hole on the second drain column 222 is the second drain hole 221. The first drain hole 211 and the second drain hole 221 are respectively arranged at one end of the first drain column 212 and the second drain column 222 away from the bottom of the first water storage tank 11, wherein the height of the first drain column 212 is lower than the height of the second drain column 222.

[0048] As the condensed water in the first water storage tank 11 continues to accumulate, the liquid level of the condensed water will be equal to the height of the first drainage column 212 . If the condensed water continues to accumulate in the first water storage tank 11 , the condensed water will be discharged through the first drainage hole 211 .

[0049] If the first drainage hole 211 is blocked due to an accident or the drainage speed is lower than the water storage speed, the liquid level in the first water storage tank 11 will exceed the height of the first drainage column 212 until the liquid level of the condensed water is equal to the height of the second drainage column 222. At this time, if the condensed water continues to accumulate in the first water storage tank 11, the condensed water will be discharged from the second drainage hole 221 to ensure the normal operation of the mobile air conditioning drainage system.

[0050] It should be noted that the height of the plurality of drainage holes is lower than the height of the opening position of the first water storage tank 11. That is, the height of the first drainage column 212 and the height of the second drainage column 222 are both smaller than the depth of the first water storage tank 11. Only in this way can it be ensured that as the condensate accumulates in the first water storage tank 11, the condensate can eventually be discharged from the first drainage hole 211 or the second drainage hole 221.

[0051] That is, the highest liquid level of the condensed water is the liquid level of the second drain column 222 . Since the height of the second drain column 222 is less than the depth of the first water storage tank 11 , the condensed water will not overflow from the first water storage tank 11 .

[0052] A centralized drainage area is arranged on the bottom of the first water storage tank 11, and a plurality of drainage columns 2 are arranged in the centralized drainage area. The bottom of the first water storage tank 11 is arranged inclined, and the centralized drainage area is located at the lowest point of the bottom of the first water storage tank.

[0053] Specifically, in order to facilitate the gathering of condensed water in the first water storage tank 11 so that the condensed water can be drained from the drainage hole more quickly, the bottom of the first water storage tank 11 is inclined, and the centralized drainage area is set at the lowest point of the first water storage tank 11, so that the condensed water can be gathered along the bottom of the first water storage tank 11 near the centralized drainage area.

[0054] Since there are multiple drainage columns 2, in order to reduce the collection points of the first water storage tank 11 and facilitate the production and processing of the water receiving tray body 1, the multiple drainage columns 2 are concentrated in the centralized drainage area, so that the first water storage tank 11 only needs to be collected in the centralized drainage area to achieve rapid discharge of condensed water.

[0055] In order to better collect the condensed water in the first water storage tank 11 , a centralized drainage area is set in the middle of the first water storage tank 11 .

[0056] In this embodiment, the first drainage column 212 and the second drainage column 222 are arranged in the middle of the first water storage tank 11 and close to the side wall of the first water storage tank 11. The bottom of the first water storage tank 11 is concave from both ends to the middle position, so that when the condensate falls into the first water storage tank 11, the condensate can be finally gathered in the middle position of the first water storage tank 11 along the bottom of the first water storage tank 11, so that the condensate can be discharged from the drainage hole at a high drainage rate.

[0057] And because the first water tank 11 is recessed from both ends to the middle position, the vertical distance from the end of the drainage column 2 located at the middle position of the first water tank 11 to the notch of the first water tank 11 will be greater than the vertical distance from the end of the drainage column 2 to the notch of the first water tank 11 when the first water tank 11 is not recessed, thereby greatly reducing the water storage capacity of the first water tank 11. When the mobile air conditioner encounters impact or vibration, the probability of condensed water splashing out of the first water tank 11 is reduced, thereby improving the overall safety of the mobile air conditioner.

[0058] An overflow baffle 12 is disposed on the bottom of the first water storage tank 11 , and the overflow baffle 12 is used to guide the water flow to flow toward the drainage column 2 .

[0059] Specifically, a plurality of flow baffles 12 are provided, and the plurality of flow baffles 12 are arranged in parallel at the bottom of the first water storage tank 11, and the plurality of flow baffles 12 extend from one end to the other end of the first water storage tank 11. A flow channel for the flow of condensed water is formed between adjacent flow baffles 12 and between the flow baffles 12 and the tank wall of the first water storage tank 11.

[0060] Each flow baffle 12 is provided with a notch at the middle of the first water storage tank 11 so that the condensed water in each flow channel can eventually be collected near the drain column 2 through each notch.

[0061] The setting of the flow baffle 12 divides the first water storage tank 11 into multiple flow channels, which increases the flow rate of the condensed water, so that the condensed water can be gathered near the drain column 2 more quickly and then be discharged from the drain hole more quickly.

[0062] It should be noted that, in order to enhance the fluidity of the condensed water, the two ends of the flow baffle 12 are not connected to the groove walls at the two ends of the first water storage groove 11 .

[0063] A water collecting trough 111 is arranged in the centralized drainage area, and a plurality of drainage columns 2 are arranged on the bottom of the water collecting trough 111 .

[0064] The flow baffle 12 is used to guide the water flow into the water collecting tank 111 .

[0065] Specifically, the water collecting tank 111 is arranged at the middle position of the bottom of the first water storage tank 11 , and a plurality of drainage columns 2 are arranged on the bottom of the water collecting tank 111 .

[0066] Providing the water collecting tank 111 can increase the water storage capacity of the first water storage tank 11, and when the condensed water flows into the water collecting tank 111, since the bottom area of ​​the water collecting tank 111 is smaller than the bottom area of ​​the first water storage tank 11, the liquid level rising rate of the condensed water can be increased, and the discharge of the condensed water from the drain hole can be accelerated.

[0067] It should be noted that the flow baffles 12 on both sides of the middle of the first water storage tank 11 extend from the tank walls at both ends of the first water storage tank 11 to the water collecting tank 111 , and the notches on the flow baffles 12 are also distributed around the water collecting tank 111 .

[0068] In a preferred embodiment, the height of the highest drainage column 2 among the plurality of drainage columns 2 is less than or equal to the depth of the water collection tank 111. For example, the height of the second drainage column 222 is less than the depth of the water collection tank 111, so as to increase the discharge rate of the condensed water from the drainage hole and reduce the accumulation of condensed water in the first water storage tank 11.

[0069] An emergency drain pipe 13 is provided on the water receiving tray body 1 , and the emergency drain pipe 13 is communicated with the first water storage tank 11 .

[0070] The emergency drain pipe 13 is detachably connected with a blocking cover.

[0071] Specifically, the emergency drain pipe 13 is disposed on a side wall of the first water storage tank 11 which is away from the drain column 2 . The emergency drain pipe 13 is communicated with the water collection tank 111 in the first water storage tank 11 .

[0072] If there is an unexpected situation that all the drainage holes are blocked or the production rate of condensed water is greater than the drainage rate of the drainage holes, in order to ensure that the condensed water in the first water storage tank 11 is discharged, an emergency drain pipe 13 is required to discharge the condensed water through the emergency drain pipe 13.

[0073] The outer surface of the end of the emergency drain pipe 13 is provided with an external thread, and the emergency drain pipe 13 is threadedly connected to the blocking cover.

[0074] Under normal circumstances, the blocking cover is threadedly connected to the emergency drain pipe 13 so as to block the water outlet of the emergency drain pipe 13, and the condensate in the first water storage tank 11 can be discharged only through the drainage hole.

[0075] If an accident occurs, the blocking cover on the emergency drain pipe 13 is removed, and a drain pipe is connected at the end of the emergency drain pipe 13 to directly discharge the condensed water in the first water storage tank 11 to the outside through the drain pipe.

[0076] A second water storage tank 1113 a is provided at the bottom of the water collection tank 111 , and the second water storage tank 1113 a is connected to the emergency drain pipe 13 .

[0077] Specifically, a second water storage tank 1113a is provided to increase the water storage capacity of the first water storage tank 11 again, and the water pressure of the condensed water in the second water storage tank 1113a is greater than the water pressure in the water collecting tank 111 and the first water storage tank 11. The second water storage tank 1113a is connected to the emergency drain pipe 13 to ensure that when the emergency drain pipe 13 needs to be used to drain water outward, there is sufficient water pressure to realize the rapid discharge of the condensed water, thereby improving the drainage rate of the condensed water.

[0078] The water collecting tank 111 includes a first water collecting part 1111, a connecting part 1112 and a second water collecting part 1113. The first water collecting part 1111, the connecting part 1112 and the second water collecting part 1113 are connected in sequence, a plurality of drainage columns 2 are arranged on the bottom of the first water collecting part 1111, and the second water collecting part 1113 is arranged close to the side wall of the first water storage tank 11 where the emergency drain pipe 13 is arranged.

[0079] The second water storage tank 1113a is arranged at the bottom of the second water collecting part 1113, and the water inlet of the emergency drain pipe 13 is arranged on the side wall of the second water storage tank 1113a close to the bottom of the tank, so as to discharge all the condensed water in the first water storage tank 11 from the emergency drain pipe 13 to the greatest extent.

[0080] The bottom of the water collecting tank 111 is inclined, and the second water storage tank 1113 a is located at the lowest point of the water collecting tank 111 .

[0081] Specifically, the connection portion is inclined from an end connected to the first water collecting portion 1111 to an end connected to the second water collecting portion 1113 , and the first water collecting portion 1111 is inclined toward the connection portion as a whole.

[0082] Therefore, when the emergency drain pipe 13 needs to drain water outward, condensed water can quickly and continuously flow from other positions in the first water storage tank 11 into the second water storage tank 1113a, thereby improving the drainage efficiency of the emergency drain pipe 13.

[0083] In summary, a drainage structure includes a water receiving tray body 1 and a drainage column 2. The drainage column 2 is arranged on the water receiving tray; wherein, at least two drainage columns 2 are arranged, and the heights of the plurality of drainage columns 2 are different, and drainage holes are arranged at the ends of the drainage columns 2, and the drainage holes connect the drainage columns 2 and the water receiving tray body 1.

[0084] The evaporator is arranged on the water receiving pan body 1, so that the condensed water generated by the evaporator condensation will fall onto the water receiving pan body 1. The condensed water falling onto the water receiving pan body 1 will eventually fall onto the condenser below the water receiving pan body 1 through the drainage hole, and will eventually be discharged to the outside under the evaporation action of the condenser.

[0085] Under normal circumstances, the condensed water can flow smoothly from the drainage holes on the drainage column 2 with the lowest height to the condenser below for discharge.

[0086] When an abnormal situation occurs and causes the drainage hole on the lowest drainage column 2 to be blocked or drainage is difficult, the water level of the condensed water in the water receiving tray body 1 will rise until the water level reaches the drainage column 2 that is second only to the lowest height, and is discharged from the drainage hole on the drainage column 2. If the drainage hole of this drainage column 2 is also blocked, the drainage will be carried out by the next drainage column 2 that is higher than this drainage column 2 until the liquid can be discharged smoothly.

[0087] By setting up multiple drainage columns 2 with different heights, condensed water can be smoothly discharged from the water receiving tray body 1, ensuring the normal operation of the mobile air conditioning drainage system, increasing the safety of the product, and solving the problem that the drainage structure of the existing water receiving tray cannot cope with the poor drainage caused by abnormal conditions.

[0088] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0089] It should be noted that the utility model takes a drainage structure as an example to introduce the specific structure and working principle of the utility model, but the application of the utility model is not limited to a drainage structure, and can also be applied to the production and use of other similar workpieces.

[0090] It should be understood that the present invention is not limited to the precise structure described above and shown in the drawings, and various modifications and changes can be made without departing from the scope thereof. The scope of the present invention is limited only by the appended claims.

[0091] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
