Description

A passive condensate overflow prevention drip tray Technical Field

[0001] This utility model relates to the field of condensate drainage technology, and more specifically, to a passive condensate overflow prevention tray. Background Technology

[0002] During the operation of various units, such as air conditioning units and refrigeration units, condensate will inevitably be generated during heat exchange. The condensate is generally collected and discharged through a condensate pan.

[0003] A search revealed Chinese patent CN209096997U, which discloses a condensate collection tray for marine air conditioning systems. This tray, designed for shipboard air conditioners, typically has a flat bottom. However, due to the ship's tilt and a small step at the drain outlet, condensate cannot drain completely, often accumulating 1-2 liters of residual water. This residual water may overflow when the ship is rocking. Common methods to prevent overflow include raising the tray height; however, this is costly and doesn't completely solve the problem. A better solution is to use longitudinal and transverse trapezoidal grooves, narrower at the bottom and wider at the top. This reduces water accumulation and facilitates cleaning. Even a small amount of condensate, such as 0.2 liters, is sufficient to fill the grooves and drain quickly through the drain pipe. Assuming the drain outlet is not blocked, no water accumulates on the bottom platform, and the remaining water in the tray is less than 0.05 liters, significantly reducing overflow.

[0004] Water collection pans are typically equipped with only a single drain outlet and a simple drainage pipe. When the drain outlet becomes clogged due to the gradual accumulation of impurities in the condensate, the lack of effective monitoring and emergency measures prevents the condensate from draining properly. As a result, the condensate quickly accumulates in the water collection pan. Once the water reaches a certain height, it overflows the pan, causing short circuits, corrosion, and other damage to electrical equipment, wiring, and other facilities around the unit. This poses a significant threat to the safe operation of the unit. Meanwhile, the problem of clogged drainage pipes is becoming increasingly frequent, requiring regular manual inspections and cleaning. However, manual inspections not only consume a lot of manpower and time but also make it difficult to achieve real-time monitoring and timely cleaning. Summary of the Invention

[0005] In order to overcome the problems and defects in the prior art, this utility model provides a passive anti-condensate overflow water collection pan to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a passive anti-condensate overflow water collection tray, comprising a water collection tray, an upper drain pipe fixedly connected to one side of the water collection tray, and a lower drain pipe fixedly connected to one side of the water collection tray near the bottom of the upper drain pipe;

[0007] Both the upper and lower drain pipes are connected to a tee pipe at one end. A condensate drain pump is installed on one side of the tee pipe. A connecting pipe is fixedly connected between the tee pipe and the condensate drain pump. A discharge pipe is fixedly connected to one side of the condensate drain pump. Sealing gaskets are fixedly installed between the upper and lower drain pipes and the water collection pan.

[0008] A water flow sensor is fixedly installed at the top of the upper drain pipe, a microcontroller is fixedly installed on one side of the water collection pan, and a cleaning mechanism is provided between the lower drain pipe and the water collection pan.

[0009] Preferably, the cleaning mechanism includes a motor, the output end of which is fixedly connected to a rotating shaft, one end of which is fixedly connected to a first gear, a bearing is fixedly installed on the outside of the drain pipe, and a filter screen is fixedly sleeved on the outside of the drain pipe.

[0010] Preferably, the bottom of the first gear is engaged with a second gear, and the second gear is fixedly sleeved on the outside of the bearing.

[0011] Preferably, a connecting shaft is fixedly connected to one side of the second gear, and a rotating plate is fixedly connected to one side of the connecting shaft.

[0012] Preferably, the rotating plate has an L-shaped cross-section, and brush bristles are fixedly connected to the inner side of the rotating plate.

[0013] Preferably, the bottom of the water flow sensor passes through the upper drain pipe and extends into the interior of the upper drain pipe.

[0014] Preferably, the microcontroller is electrically connected to both the water flow sensor and the motor.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. The drain pipe drains water according to the principle of water flowing downhill, ensuring that condensate is discharged from the sump in a timely manner to prevent water accumulation. If the drain pipe is blocked, the upper drain pipe can be activated as an emergency drainage channel. With the intelligent monitoring and control of the water flow sensor and the microcontroller, it effectively avoids excessive accumulation of condensate in the sump and overflow, which greatly improves the reliability and stability of drainage, effectively ensures the dryness and safety of the surrounding environment of the unit, and reduces the risk of electrical failures, equipment corrosion and other problems caused by condensate overflow.

[0017] 2. By working in conjunction with a water flow sensor, a microcontroller, and a motor, the system automatically detects and cleans blockages in the lower drain pipe. When the water flow sensor detects water flowing through the upper drain pipe, the microcontroller quickly starts the motor, driving the rotating shaft, gear set, and connecting shaft to rotate. This causes the rotating plate and brushes to scrape and clean the filter screen. This eliminates the need for frequent manual inspections and cleaning, saving labor costs and promptly restoring the drainage capacity of the lower drain pipe. This ensures the continuous and efficient operation of the drainage system, reduces downtime caused by poor drainage, and improves the overall operating efficiency of the unit.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] As shown in Figures 1-5, a passive anti-condensate overflow water collection tray includes a water collection tray 1, an upper drain pipe 2 is fixedly connected to one side of the water collection tray 1, and a lower drain pipe 3 is fixedly connected to one side of the water collection tray 1 near the bottom of the upper drain pipe 2.

[0026] One end of the upper drain pipe 2 and the lower drain pipe 3 is connected to a tee pipe 4. A condensate drain pump 5 is installed on one side of the tee pipe 4. A connecting pipe 6 is fixedly connected between the tee pipe 4 and the condensate drain pump 5. A discharge pipe 7 is fixedly connected to one side of the condensate drain pump 5. A sealing gasket 8 is fixedly installed between the upper drain pipe 2 and the lower drain pipe 3 and the water collection pan 1.

[0027] A water flow sensor 9 is fixedly installed on the top of the upper drain pipe 2, a microcontroller 10 is fixedly installed on one side of the water collection pan 1, and a cleaning mechanism is provided between the lower drain pipe 3 and the water collection pan 1.

[0028] As shown in Figures 1-4, the cleaning mechanism includes a motor 11, a rotating shaft 12 is fixedly connected to the output end of the motor 11, a first gear 13 is fixedly connected to one end of the rotating shaft 12, a bearing 15 is fixedly installed on the outside of the lower drain pipe 3, and a filter screen 16 is fixedly sleeved on the outside of the lower drain pipe 3 to facilitate the filtration of impurities in the condensate.

[0029] As shown in Figures 1-5, the bottom of the first gear 13 meshes with the second gear 14, which is fixedly sleeved on the outside of the bearing 15. A connecting shaft 17 is fixedly connected to one side of the second gear 14, and a rotating plate 18 is fixedly connected to one side of the connecting shaft 17. The rotating plate 18 has an L-shaped cross-section, and brush bristles 19 are fixedly connected to the inside of the rotating plate 18. The bottom of the water flow sensor 9 passes through the upper drain pipe 2 and extends into the interior of the upper drain pipe 2. The microcontroller 10 is electrically connected to the water flow sensor 9 and the motor 11. When the water flow sensor 9 detects water, it indicates that the filter screen cylinder 16 is blocked, affecting the drainage efficiency. Thus, the microcontroller 10 can drive the rotating plate 18 to rotate, thereby allowing the rotating plate 18 and the brush bristles 19 to brush the filter screen cylinder 16.

[0030] Working principle of this utility model: The passive anti-condensate overflow condensate tray provided by this utility model is used to collect condensate generated by the unit. Under normal circumstances, the condensate will be discharged through the lower drain pipe 3. Because its position is relatively low, it conforms to the natural law of water flowing downhill and is the main drainage channel. The lower drain pipe 3 and the condensate tray 1 are fixedly connected by a sealing gasket 8 to ensure the sealing of the connection and prevent water leakage. At the same time, the upper drain pipe 2 serves as a backup drainage channel. Under normal circumstances, there is basically no water flowing through it. One end of the lower drain pipe 3 and the upper drain pipe 2 are connected to a T-pipe 4. The condensate drain pump 5 installed on one side of the T-pipe 4 is connected to the T-pipe 4 through a connecting pipe 6. The condensate flowing from the lower drain pipe 3 or the upper drain pipe 2 into the T-pipe 4 is discharged through the discharge pipe 7 to the designated drainage position, such as the bathroom drain outlet, to ensure that the condensate can be discharged in a timely and effective manner and to prevent excessive accumulation in the condensate tray 1 and overflow.

[0031] The water flow sensor 9 is installed at the top of the upper drain pipe 2. Its bottom passes through the upper drain pipe 2 and extends into the upper drain pipe 2. It can monitor in real time whether there is water flow in the upper drain pipe 2. During normal drainage, since the lower drain pipe 3 is unobstructed, there is no water flow in the upper drain pipe 2, and the water flow sensor 9 has no signal output. When the liquid level in the water collection pan 1 rises to the height of the upper drain pipe 2 due to blockage of the lower drain pipe 3 or other reasons, the condensate begins to flow into the upper drain pipe 2. The water flow sensor 9 detects the water flow and transmits the signal to the microcontroller 10. The microcontroller 10 is electrically connected to the water flow sensor 9 and the motor 11. After receiving the signal from the water flow sensor 9, the microcontroller 10 determines that the lower drain pipe 3 may be blocked.

[0032] Then, the microcontroller 10 starts the motor 11, and its output drives the rotating shaft 12 to rotate. The first gear 13, which is fixedly connected to one end of the rotating shaft 12, rotates accordingly. The second gear 14, which meshes with the bottom of the first gear 13, is fixedly sleeved on the outside of the bearing 15. Driven by the first gear 13, the second gear 14 begins to rotate. The connecting shaft 17, which is fixedly connected to one side of the second gear 14, rotates with the rotation of the second gear 14. The rotating plate 18, which has an L-shaped cross-section, is also fixedly connected to one side of the connecting shaft 17 and rotates synchronously. During the rotation, the bristles 19, which are fixedly connected to the inner side of the rotating plate 18, brush against the outer side of the drain pipe 3. The filter screen 16 is cleaned by scraping. The filter screen 16 can initially filter out impurities in the condensate and prevent them from entering the lower drain pipe 3 and causing blockage. However, after long-term use, impurities may adhere to the filter screen 16 and affect the drainage efficiency. At this time, the rotating cleaning action of the rotating plate 18 and the brush 19 can remove these impurities in time and restore the drainage capacity of the lower drain pipe 3. At the same time, the upper drain pipe 2 continues to drain water as a temporary drainage channel to prevent condensate from overflowing into the water collection pan 1, thereby realizing the passive anti-condensate overflow function. The automatic cleaning mechanism improves the reliability and stability of the drainage system and ensures the normal operation of the unit.

[0033] In conclusion, the above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
