Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for central integrated air conditioning, and in particular to a negative pressure self-priming discharge device for condensate water in central integrated air conditioning. Background Technology

[0002] In commercial buildings, large office spaces, and industrial plants, central integrated air conditioning systems have become the mainstream air conditioning equipment due to their advantages such as high cooling and heating efficiency and wide temperature control range. During operation, the evaporator surface temperature of such systems is relatively low, causing water vapor in the air to condense and form condensate. If this condensate is not effectively drained in a timely manner, it will not only affect the heat exchange efficiency of the air conditioning system but may also cause condensate overflow, damaging interior decorations and electrical equipment, and even leading to mold growth and a decline in indoor air quality.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: Condensate drainage devices mostly use conventional water pumps to drive drainage. Although this can get rid of the dependence on gravity slope to a certain extent, the drainage device lacks an effective filtration structure. Dust and impurities contained in the condensate can easily enter the water pump, causing water pump wear and blockage, and shortening the service life of the equipment. Utility Model Content

[0004] The technical problem to be solved by this utility model is that existing condensate drainage devices mostly use conventional water pumps to drive drainage. Although this can get rid of the dependence on gravity slope to a certain extent, the drainage device lacks an effective filtration structure. Dust and impurities contained in the condensate can easily enter the water pump, causing water pump wear and blockage, and shortening the service life of the equipment. To this end, we propose a central integrated air conditioning condensate negative pressure self-priming drainage device.

[0005] To achieve the above objectives, this application adopts the following technical solution: a central integrated air conditioning condensate negative pressure self-priming discharge device, comprising a mounting shell: a cover plate is fixedly installed on the surface of the mounting shell, an inlet pipe is installed inside the cover plate and connected to the air conditioning condensate pipe, a drain outlet is installed on the side wall of the mounting shell and connected to an external drain pipe, and two mounting plates are fixedly connected to both sides of the mounting shell, with mounting holes opened on the surface of the mounting plates for installation. The side wall of the housing is equipped with a connection socket. A mounting bracket is fixedly connected to the inner cavity of the housing. A condensate pump is fixedly installed on one side of the mounting bracket. A connecting wire is electrically connected to the surface of the condensate pump. The connecting wire is electrically connected to the connection socket. A discharge pipe and a suction pipe are respectively installed on the surface of the condensate pump. The discharge pipe and the drain outlet are sealed and connected. A negative pressure chip is installed inside the condensate pump. An alarm is installed on the surface of the housing. The negative pressure chip and the alarm are wirelessly connected. A water collection tank is installed in the inner cavity of the housing. The water collection tank is made of acrylic sheet. The condensate pump is located in the inner cavity of the water collection tank.

[0006] Preferably, the surface of the mounting shell is provided with an observation window and scale lines.

[0007] Preferably, a handle is fixedly connected to the surface of the cover plate, and the surface of the handle is provided with anti-slip protrusions.

[0008] Preferably, a bubble level is installed on the surface of the cover plate.

[0009] Preferably, the surface of the mounting plate has a groove, which is connected to the mounting hole, and the inner wall of the groove is interference-fitted with a sealing plug.

[0010] Preferably, a sealing gasket is fixedly connected to one side of the cover plate, and one side of the sealing gasket is in contact with the mounting shell.

[0011] Preferably, a number of rubber strips are fixedly connected to the back of the mounting shell, and the rubber strips are distributed in a linear array on the back of the mounting shell.

[0012] Preferably, a filter cartridge is installed internally on the inlet pipe, and the filter cartridge is located inside the water collection tank. The technical effects and advantages of this utility model are as follows: In this invention, a condenser pump, in conjunction with an internal negative pressure chip, forms a negative pressure self-priming structure, which can actively and efficiently extract air conditioner condensate. Compared to traditional gravity drainage, this avoids drainage problems caused by condensate retention. The design of a direct connection between the inlet pipe and the air conditioner condensate pipe, and a sealed connection between the drain outlet and the external drain pipe, allows for flexible adaptation to different specifications of central integrated air conditioning systems. Simultaneously, the negative pressure chip is wirelessly linked to an alarm. When the device experiences abnormal negative pressure or condenser pump malfunction leading to drainage obstruction, the alarm will promptly sound a warning, alerting staff to investigate the problem and preventing condensate overflow that could damage the air conditioning equipment or the surrounding environment. Furthermore, the sealed connection between the condenser pump's discharge pipe and the drain outlet effectively prevents condensate leakage. The mounting shell and cover form a relatively enclosed protective space, protecting the internal condensate... Core components such as pumps and negative pressure chips are protected from external dust, extending the overall service life of the device. Attached Figure Description

[0015] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0016] Reference Figure 1-5 As shown, this utility model provides a technical solution: a central integrated air conditioning condensate negative pressure self-priming discharge device, including a mounting shell 1; a cover plate 2 is fixedly installed on the surface of the mounting shell 1, and a water inlet pipe 4 is installed inside the cover plate 2, which is connected to the air conditioning condensate pipe; a drain outlet 3 is installed on the side wall of the mounting shell 1, which is connected to an external drain pipe; two mounting plates 6 are fixedly connected to both sides of the mounting shell 1. Mounting holes 7 are provided on the surface of mounting housing 1. A connection socket 5 is installed on the side wall of mounting housing 1. A mounting bracket 8 is fixedly connected to the inner cavity of mounting housing 1. A condenser pump 9 is fixedly installed on one side of mounting bracket 8. A connecting wire 10 is electrically connected to the surface of condenser pump 9. The connecting wire 10 is electrically connected to the connection socket 5. A discharge pipe 11 and a suction pipe 12 are respectively installed on the surface of condenser pump 9. The discharge pipe 11 and the drain outlet 3 are sealed and connected. A negative pressure chip is installed inside condenser pump 9. An alarm is installed on the surface of mounting housing 1. The negative pressure chip is wirelessly connected to the alarm. A water collection tank 13 is installed in the inner cavity of mounting housing 1. The water collection tank 13 is made of acrylic sheet. The condenser pump 9 is located in the inner cavity of water collection tank 13. The condenser pump 9, in conjunction with the internal negative pressure chip, forms a negative pressure self-priming structure, which can actively and efficiently extract air conditioner condensate. Compared with the traditional gravity drainage method, it can avoid drainage problems caused by condensate stagnation. The design of the inlet pipe 4 directly connecting to the air conditioner condensate pipe and the drain outlet 3 sealingly connecting to the external drain pipe allows it to flexibly adapt to different specifications of central integrated air conditioning systems. At the same time, the negative pressure chip and the alarm are wirelessly linked. When the device experiences abnormal negative pressure or condenser pump 9 failure, resulting in drainage obstruction, the alarm can issue a warning in time, reminding staff to check the problem and prevent condensate overflow from damaging the air conditioning equipment or the surrounding environment. In addition, the discharge pipe 11 of the condenser pump 9 and the drain outlet 3 adopt a sealed connection design to effectively prevent condensate leakage. The mounting shell 1 and the cover plate 2 form a relatively closed protective space, which can protect the internal condenser pump 9, negative pressure chip and other core components from external dust and extend the overall service life of the device.

[0017] Reference Figure 1 and Figure 2 As shown in this embodiment: an observation window 14 is provided on the surface of the mounting shell 1, and a scale line 15 is provided on the surface of the mounting shell 1. The condensate level of the internal water collection tank 13 can be directly observed through the observation window 14, and the water volume can be accurately determined with the help of the scale line 15. This allows for quick monitoring of the condensate collection and drainage progress, advance prediction of drainage needs to avoid overflowing the water tank, and reduces interference to the device's sealing and internal components caused by frequent opening and inspection.

[0018] Reference Figure 2 and Figure 3 As shown in this embodiment, a handle 16 is fixedly connected to the surface of the cover plate 2, and the surface of the handle 16 is provided with anti-slip protrusions. By setting the handle 16, a clear point of force is provided for workers to open or close the cover plate 2, allowing for easy operation without the need for tools. This greatly improves the convenience of daily maintenance of the device. At the same time, the anti-slip protrusions can effectively increase the friction between the hand and the handle 16, so that even if the hand is covered with condensation or dust, it can be held firmly, avoiding slippage during operation that could cause hand injury or the cover 2 to fall off accidentally.

[0019] Reference Figure 3As shown in this embodiment: a bubble level is installed on the surface of the cover plate 2. 17. With the bubble level 17, the staff does not need to carry additional leveling tools when installing the housing 1. By observing the position of the bubble in the bubble level 17, they can quickly determine whether the device is in a horizontal state, ensuring that the core components such as the condensate pump 9 and the water collection tank 13 are installed horizontally. This avoids uneven distribution and local stagnation of condensate in the water collection tank 13 due to device tilting, or affects the negative pressure self-priming efficiency of the condensate pump 9.

[0020] Reference Figure 2 As shown in this embodiment: a groove is formed on the surface of the mounting plate 6, and the groove is connected to the mounting hole 7. The inner wall of the groove is press-fitted with a sealing plug 18. The sealing plug 18, which is press-fitted with the inner wall of the groove of the mounting plate 6, achieves the effect of protecting the mounting bolts in the mounting hole 7, avoiding the corrosion of the mounting bolts by dust or other impurities, and improving the practicality of the device.

[0021] Reference Figure 5 As shown in this embodiment: a sealing gasket is fixedly connected to one side of the cover plate 2. 20. One side of the sealing gasket 20 is in contact with the mounting housing 1. By setting the sealing gasket 20, on the one hand, a reliable sealing barrier can be formed between the cover plate 2 and the mounting housing 1, which can effectively prevent external dust, impurities, etc. from entering the interior of the mounting housing 1, prevent them from adhering to the surface of the condensate pump 9, prevent the components from malfunctioning due to contamination, and ensure the cleanliness of the device and the stable operation of the core components. On the other hand, it can enhance the sealing of the mounting housing 1, reduce the leakage of moisture generated by the evaporation of internal condensate, and at the same time prevent changes in the external ambient temperature from interfering with the working state of the internal components.

[0022] Reference Figure 3 As shown in this embodiment, a plurality of rubber strips 19 are fixedly connected to the back of the mounting shell 1, and the plurality of rubber strips 19 are distributed in a linear array on the back of the mounting shell 1. The rubber strips 19 have good elasticity and friction. When the mounting shell 1 is installed on the wall, it can fit tightly against the mounting surface, increasing the frictional resistance between the device and the carrier, effectively preventing the device from shifting or slipping due to long-term operation vibration or slight external impact, and improving the stability of the mounting shell 1.

[0023] Reference Figure 5 As shown in this implementation scheme: a filter cartridge is installed on the internal thread of the water inlet pipe 4. 21. The filter cartridge 21 is located inside the water collection tank 13. The filter cartridge 21, installed through the internal thread of the water inlet pipe 4, can pre-filter the air conditioning condensate entering the device. It can effectively intercept pollutants such as dust, impurities, and microbial flocculents that may be contained in the condensate, preventing them from depositing after entering the water collection tank 13 with the water flow. This prevents scale buildup on the inner wall of the water collection tank 13 or blockage of the suction pipe 12 and discharge pipe 11 of the condensate pump 9, ensuring smooth condensate flow and maintaining the high efficiency and stability of the negative pressure self-priming function of the condensate pump 9. At the same time, the filtered clean condensate can reduce the corrosion of the condensate pump 9, reduce the probability of component failure caused by impurities wear or blockage, and extend the service life of the components. In addition, the threaded installation method makes it easy for staff to disassemble the filter cartridge 21 for regular cleaning or replacement.

[0024] Working principle: First, during the installation phase, the device is positioned using the linear array of rubber strips 19 on the back of the mounting shell 1 and the bubble level 17 on the surface of the cover plate 2. The rubber strips 19 enhance the stability of the fit between the device and the mounting surface through elasticity and friction, while the bubble level 17 helps the staff quickly calibrate the horizontal state of the device, ensuring that the core components such as the internal water collection tank 13 and the condensate pump 9 are in a horizontal working position, avoiding uneven distribution of condensate due to tilting. At the same time, the mounting shell 1 is fixed to the mounting surface through the mounting holes 7 of the mounting plate 6, and the sealing plug 18 in the groove protects the mounting bolts, preventing impurities from corroding and affecting the fixing effect. When the device is running, the condensate generated by the air conditioner flows into the inlet pipe 4, which is connected to the cover plate 2, through the air conditioner condensate pipe. The threaded filter cartridge 21 inside the inlet pipe 4 first filters the condensate, intercepting dust, impurities, and microbial flocs in the water to prevent contaminants from entering subsequent components and causing blockage or wear. The filtered clean condensate flows directly into the acrylic water collection tank 13 inside the mounting shell 1 for temporary storage. Then, the power is connected through the connection port 5, and the condensate pump 9 starts. Its internal negative pressure chip generates a negative pressure environment, and the condensate pump 9 actively draws condensate from the water collection tank 13 through the suction pipe 12, and then discharges the condensate stably into the external drain pipe through the discharge pipe 11, achieving efficient self-priming drainage that is independent of gravity. At the same time, the sealing design of the discharge pipe 11 and the drain port 3 prevents condensate leakage. During operation, the operator can intuitively and accurately monitor the condensate in the water collection tank 13 through the observation window 14 on the surface of the mounting shell 1 and the scale line 15. The liquid level is monitored to track the collection and discharge progress. If the negative pressure chip detects abnormal negative pressure, condensate pump 9 failure, or other situations that cause drainage obstruction, it will immediately trigger the alarm on the surface of the mounting shell 1 via wireless signal to promptly remind staff to investigate the problem and prevent condensate from overflowing.

[0025] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
