Description

Technical Field

[0001] This utility model relates to energy-saving technology for air conditioning systems, specifically to a condensate recovery device for air conditioning systems. Background Technology

[0002] When the air conditioner is in cooling mode, the indoor air flows through the evaporator of the air conditioner unit and exchanges heat. Water vapor in the air condenses to form condensate, which falls into the condensate collection tank. The upper end of the drain pipe is connected to the bottom of the condensate collection tank, and the condensate flows out of the outside of the air conditioner along the drain pipe.

[0003] In modern life, air conditioning is basically standard equipment in subway stations. Subway station air conditioning systems generate a large amount of condensate water every day. The existing condensate water treatment has the following problems: 1. Simple recycling device: Some stations use fixed containers to collect condensate, but this requires manual monitoring of the water level and manual drainage, which has problems such as high operation and maintenance costs and easy overflow. 2. Insufficient automation: Existing technologies lack integrated design for intelligent water level detection and automatic discharge, making it impossible to achieve closed-loop management of "collection-utilization-recollection".

[0004] Developing low-power, maintenance-free automated recycling devices under the unique constraints of compact space and high passenger flow in subways has become a pressing technical challenge for the industry. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide an air conditioning system condensate recovery device that can realize the collection, utilization and re-collection of air conditioning condensate, while being low power consumption and maintenance-free.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a condensate recovery device for an air conditioning system, comprising: A water collection container, wherein the water collection container is provided with a liquid inlet that can be connected to the drain pipe of the air conditioner, and the water collection container is provided with a water outlet; A sealing plate, which can be detachably plugged onto the outlet; A drainage assembly includes a water supply pipe connected to the water outlet; A floating assembly, disposed within the water collection container, wherein the weight of the floating assembly is less than its buoyancy in the condensate; and A drainage drive mechanism is disposed inside the water collection container and connected to the sealing plate. When the floating component floats to the top of the water collection container, it can trigger the drainage drive mechanism to start. The drainage drive mechanism can drive the sealing plate to disengage from the water outlet and can drive the sealing plate to re-block the water outlet after the liquid in the water collection container has been drained.

[0007] Furthermore, the drainage drive mechanism includes an elastic connector, a support rod, a lever, a pull rod, a permanent magnet, and an electromagnet. The elastic connector connects the sealing plate and the water collection container, and under the pull of the elastic connector, the sealing plate blocks the water outlet. The support rod is vertically arranged inside the water collection container. The middle part of the lever is hinged to the support rod. The pull rod is vertically arranged, with its bottom end connected to the sealing plate and its top end slidably hinged to one end of the lever. The permanent magnet is embedded in the other end of the lever. The electromagnet is located at the top inside the water collection container and directly above the permanent magnet. When energized, the electromagnet generates the same magnetism as the permanent magnet, and the magnetic force generated by the electromagnet and the permanent magnet is greater than the pulling force of the elastic connector. The energizing switch of the electromagnet is a pressure switch, which triggers the energizing of the electromagnet when the floating component rises to the top.

[0008] Furthermore, it also includes a first guide member, which is fixed inside the water collection container. The first guide member has a vertically arranged first guide hole, and the pull rod is slidably inserted into the first guide hole.

[0009] Furthermore, it also includes a second guide member, which includes a guide rod that is vertically disposed inside the water collection container, and the floating assembly can be slidably sleeved on the guide rod.

[0010] Furthermore, regarding the cleaning structure, the cleaning structure is located on an annular body adapted to the inner wall of the water collection container. The outer wall of the cleaning structure can slide in contact with the inner wall of the water collection container and can rise or fall within the water collection container.

[0011] Furthermore, the cleaning structure includes a frame float and a brush disposed on the outer wall of the frame float in the circumferential direction. The frame float floats on the surface of the condensate water, and the end of the brush contacts the interior of the water collection container.

[0012] Furthermore, it also includes a drainage assembly, which further includes a nozzle mounted on the water supply pipe.

[0013] The beneficial effects of this utility model are: In the aforementioned air conditioning system condensate recovery device, when the condensate generated by the air conditioner enters the collection container through the drain pipe, the liquid level gradually rises, causing the floating component to rise accordingly. When the liquid level reaches a set height, the floating component triggers the drainage drive mechanism, causing the sealing plate to open, and the condensate is discharged from the outlet and transported to its destination for recycling through the water supply pipe. As the liquid level drops, the floating component falls back down, the sealing plate closes again, and it awaits the next drainage cycle.

[0014] The beneficial effects of this device are: it realizes the automatic collection and discharge of condensate through a purely mechanical structure, enabling the collection, utilization and recollection of air conditioner condensate, while being low in power consumption and maintenance-free; in addition, it can reduce the immersion and corrosion of the wall surface near the air conditioner's drain pipe.

[0017] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention; therefore, the invention is not limited to the specific embodiments disclosed below.

[0018] Please see Figures 1 to 3 This utility model provides a condensate recovery device for an air conditioning system, including a water collection container 100, a sealing plate 200, a drainage component 300, a floating component 400, and a drainage drive mechanism 500.

[0019] Specifically, the water collection container 100 is provided with a liquid inlet that can be connected to the drain pipe of the air conditioner, and the water collection container 100 is provided with a water outlet. The sealing plate 200 is detachably plugged on the water outlet. The drainage assembly 300 includes a water supply pipe that is connected to the water outlet.

[0020] A floating component 400 is disposed within the water collection container 100, and the weight of the floating component 400 is less than its buoyancy in the condensate. A drainage drive mechanism 500 is disposed within the water collection container 100 and connected to the sealing plate 200. When the floating component 400 floats to the top of the water collection container 100, it can trigger the drainage drive mechanism 500 to start. The drainage drive mechanism 500 can drive the sealing plate 200 to detach from the outlet and can drive the sealing plate 200 to re-block the outlet after the liquid in the water collection container 100 has been drained.

[0021] In operation, as the condensate from the air conditioner enters the collection container 100 through the drain pipe, the liquid level gradually rises, causing the float assembly 400 to rise accordingly. When the liquid level reaches a set height, the float assembly 400 triggers the drain drive mechanism 500, opening the sealing plate 200. The condensate is then discharged from the outlet and transported to its destination for recycling via the water pipe. As the liquid level drops, the float assembly 400 falls back down, and the sealing plate 200 closes again, awaiting the next drainage cycle.

[0022] The advantages of this device are: it achieves automatic collection and discharge of condensate through a purely mechanical structure, requiring no external power supply and resulting in low operating costs. Simultaneously, it reduces water immersion and corrosion on the walls near the air conditioner's drain pipe.

[0023] In this embodiment, the drainage drive mechanism 500 includes an elastic connector 510, a support rod 520, a lever 530, a pull rod 540, a permanent magnet 550, and an electromagnet 560. The elastic connector 510 is connected between the sealing plate 200 and the water collection container 100, and the sealing plate 200 is blocked at the water outlet under the pull of the elastic connector 510. The support rod 520 is vertically arranged inside the water collection container 100. The middle part of the lever 530 is hinged to the support rod 520. The pull rod 540 is vertically arranged, and the bottom end of the pull rod 540 is connected to the sealing plate 200. The top end of the lever 530 can be slidably hinged to one end. The permanent magnet 550 is embedded in the other end of the lever 530. The electromagnet 560 is set inside the top of the water collection container 100 and is located directly above the permanent magnet 550. When the electromagnet 560 is energized, it can generate the same magnetism as the permanent magnet 550. The magnetic force generated by the electromagnet 560 and the permanent magnet 550 is greater than the pulling force of the elastic connector 510. The energizing switch of the electromagnet 560 is a pressure switch. When the floating component 400 rises to the top, it can trigger the energizing of the electromagnet 560.

[0024] In normal use, under the action of the elastic connector 510, the sealing plate 200 blocks the outlet. At this time, the end of the lever 530 connected to the pull rod 540 is lower than the end of the lever 530 where the permanent magnet 550 is installed. As the liquid level of the condensate gradually rises, when the floating component 400 rises to the top, it triggers the switch of the electromagnet 560 to energize it. The repulsive force generated between the electromagnet 560 and the permanent magnet 550 drives this end of the lever 530 to descend. The pull rod 540 can then pull the lever 530 to rise a certain distance, thereby causing the sealing plate 200 to detach from the outlet. The water collection container 100 drains instantly. Subsequently, the sealing plate 200 slowly descends. When the condensate drops to the preset position, the sealing plate 200 blocks the outlet again.

[0025] It should be noted that, in practical implementation, in order to ensure that the condensate in the water collection container 100 is discharged as much as possible, the tension of the elastic connector 510 needs to be much less than the repulsive force between the permanent magnet 550 and the electromagnet 560. That is, the sum of the tension and the weight of the sealing plate 200 should be slightly greater than the buoyancy it experiences, just enough to seal and block the outlet.

[0026] In a preferred embodiment, the device further includes a first guide member 600, which is fixed inside the water collection container 100. The first guide member 600 has a vertically arranged first guide hole, and the pull rod 540 is slidably inserted into the first guide hole. Guided by the first guide member 600, the sealing plate 200 can be accurately blocked at the water outlet.

[0027] In another preferred embodiment, the device further includes a second guide member 700, which includes a guide rod that is vertically disposed inside the water collection container 100, and the floating assembly 400 is slidably sleeved on the guide rod.

[0028] The second guide 700 ensures that the floating assembly 400 can be installed vertically and accurately make contact with the electromagnet 560.

[0029] In a more preferred embodiment, the device further includes a cleaning structure 800, which is an annular body adapted to the inner wall of the water collection container 100. The outer wall of the cleaning structure 800 can slide in contact with the inner wall of the water collection container 100 and can rise or fall within the water collection container 100.

[0030] Specifically, the cleaning structure 800 includes a frame float 810 and a brush 820 disposed on the outer wall of the circumferential frame float 810, with the end of the brush 820 in contact with the interior of the water collection container 100.

[0031] During the process of the cleaning structure 800 rising or falling, the water collection container 100 is cleaned by the brush 820.

[0032] In addition, in specific implementation, a nozzle 310 can be installed on the water supply pipe and the nozzle 310 can be kept in the open state. When the water collection container 100 drains water, the object can be sprayed again through the nozzle 310, thereby improving the cleaning effect.

[0033] How to use the above-mentioned air conditioning system condensate recovery device: Connect the liquid inlet to the drain pipe of the air conditioning system. When the condensate in the water collection container 100 reaches the preset height, the water collection container 100 will drain once. The condensate will be discharged from the water supply pipe and sprayed through the nozzle 310 to clean the outer wall components.

[0034] During use, the cleaning structure 800 can clean the side wall of the water collection container 100 on its own, reducing the chance of dirt accumulating on the inner wall of the water collection container 100.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
