Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to a drainage filter structure for air conditioning units. Background Technology

[0002] DCS server rooms have high environmental requirements, necessitating air conditioning units with large cooling capacity to maintain constant temperature and humidity. Central air conditioning systems are commonly used; while they offer good cooling performance, they produce a large amount of condensate. This condensate is collected in a drip tray at the bottom of the unit and drained through a drain pipe. However, technicians discovered the following problem with the drip tray during operation:

[0003] (1) The drip tray is made of iron, which produces a lot of rust residue over time, but the space below is too small to clean it.

[0004] (2) The drain outlet of the water tray is very narrow and is easily blocked by rust. Once the water tray is full of condensate, it will overflow outside the unit, causing indoor items to be soaked in water. Utility Model Content

[0042] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0043] This utility model embodiment provides a drainage filtration structure for an air conditioning unit. Please refer to... Figures 1-5 This air conditioning unit's drainage and filtration structure includes a drip tray for collecting condensate from the air conditioner. A drain pipe is connected to its side, allowing the condensate flowing from the air conditioner unit into the drip tray to be filtered. The structure comprises a mounting plate assembly and a filter frame assembly. The filter frame assembly is connected to the side wall of the mounting plate assembly. The mounting plate assembly is fitted onto the side 40 of the drip tray, placing the filter frame assembly within the tray. A drain channel 110 is located on the mounting plate assembly and connects to the drain pipe. After the condensate discharged from the air conditioner unit falls into the drip tray, it is filtered by the filter frame assembly before flowing into the drain outlet 400 of the drain pipe, preventing the drain pipe from becoming clogged.

[0044] Specifically (taking a water tray with a height of 3cm as an example).

[0045] The mounting plate assembly includes a hook rod 10 and a positioning plate 11, with the hook rod 10 connected to the top of the positioning plate 11. To allow the mounting plate assembly to be hooked onto the side 40 of the water receiving tray, a through groove 100 matching the side 40 of the water receiving tray is provided at the bottom of the hook rod 10. That is, the thickness of the side 40 of the water receiving tray does not exceed the width of the through groove 100, allowing the hook rod 10 to be hooked onto the side 40 of the water receiving tray through the through groove 100, thereby allowing the positioning plate 11 to be placed inside the water receiving tray. Preferably, when the mounting plate assembly is hooked onto the side 40 of the water receiving tray, the bottom end of the positioning plate 11 is connected to the bottom end of the water receiving tray. The positioning plate 11 has a drainage channel 110 laterally provided to match the drain outlet 400, that is, when the positioning plate 11 is placed inside the water receiving tray via the hook rod 10, the drainage channel 110 communicates with the drain outlet 400 of the drain pipe.

[0046] The filter frame assembly includes multiple filter enclosures 202. Each filter enclosure 202 is connected at both ends to positioning plates 11 on both sides of the drainage channel 110, thus enclosing the outer area of ​​the drainage channel 110. Therefore, the condensate filtered by the filter frame assembly flows through the drainage channel 110 to the drain outlet 400 of the drain pipe. Furthermore, the filter enclosures 202 are arranged in a nested pattern, with the size gradually increasing from the inside out, and a collection space 22 is left between adjacent filter enclosures 202. Preferably, the filter frame assembly includes six filter enclosures 202, and the height of each filter enclosure 202 is 2 cm. Each filter enclosure 202 has a first filter hole group 201.

[0047] When the condensate from the air conditioner falls into the drip tray, the condensate in the drip tray can be filtered through multiple filter screens 202 before flowing into the drain pipe. This causes rust to be trapped in the collection space 22, thus preventing a large amount of rust from clogging the drain outlet 400 when it flows into the drain pipe with the condensate.

[0048] To further enhance the filtration capacity of the filter assembly for air conditioning condensate, an overflow baffle is connected to the top of the innermost filter enclosure (hereinafter referred to as the "innermost filter enclosure") in the filter assembly. This overflow baffle has a cover 31, through which a second filter hole group extends from top to bottom. This second filter hole group includes a plurality of evenly spaced second filter holes 320.

[0049] The overflow baffle can adopt one of the following three structures: First, the overflow baffle is a fully enclosed cover, which is connected to the top of the innermost filter fence, making the top of the innermost filter fence completely sealed; Second, the overflow baffle is a semi-enclosed cover, which is connected to the top of the innermost filter fence, leaving an opening near the positioning plate 11 on its top surface; Third, the overflow baffle can also consist of a semi-enclosed cover and an overflow frame 30. The semi-enclosed cover is connected to the top of the innermost filter fence, making the top of the innermost filter fence semi-closed. The overflow frame 30 matches the open side of the top of the innermost filter fence and is connected to the innermost filter fence, making the overflow frame 30 and the innermost filter fence interconnected. The overflow frame 30 is a hollow frame structure with an opening on one side, formed by multiple rods. The overflow frame 30 is connected to the side wall of the cover 31 with its circumferential sealing side, and its circumferential open side is installed on the side wall of the positioning plate 11. In this case, the height of the overflow frame 30 is greater than the height of the cover 31. Preferably, the height of the cover 31 can be 0.2 cm, and the height of the rod of the overflow frame 30 can be 0.5 cm.

[0050] When each filter enclosure 202 is about to reach its filtration limit, causing the drainage volume of the drain pipe to be less than the water production of the air conditioning unit, the condensate water level in the drip tray rises and overflows to the top of the innermost filter enclosure. At this time, if the overflow baffle is only a fully enclosed or semi-enclosed cover, the overflowing condensate water will be filtered again through the second filter hole 320; if an overflow baffle with a semi-enclosed cover and an overflow frame 30 is used, the overflowing condensate water will be filtered in time through the second filter hole 320 under the obstruction of the overflow frame 30.

[0051] Based on the above embodiments, the working principle of this application is as follows:

[0052] First, attach the above-mentioned air conditioning unit drainage filter structure to the side 40 of the water collection tray, so that the filter frame is set inside the water collection tray. Then, place the water collection tray below the air conditioning unit to facilitate the collection of air conditioning condensate.

[0053] The condensate discharged downwards from the air conditioning unit flows into the drain pipe after being filtered by each filter enclosure 202. Rust and other contaminants in the condensate are trapped in the collection space 22. When the filter enclosure 202 is about to reach its filtration limit, the condensate in the drip tray overflows to the top of the innermost filter enclosure due to the rising water level, where it is filtered again by the overflow baffle. If the filter enclosure 202 becomes clogged and unable to filter the condensate, simply remove the drainage filter structure, clean it, and then reattach it to the drip tray for normal filtration to resume.

[0054] Based on the above embodiments, the advantages of this application are:

[0055] By connecting nested filter enclosures 202 to the positioning plate 11, with collection spaces 22 between adjacent filter enclosures 202, the filter enclosures 202 filter condensate while trapping rust residue in the collection spaces 22, thus preventing large amounts of rust residue from flowing into the drain pipe and clogging it. Furthermore, the filtration capacity of the filter frame assembly is further enhanced by adding an overflow baffle at the top of the innermost filter enclosure. In addition, this drainage filtration structure is connected to the water tray via a hook-and-loop connection, making it easy to assemble, disassemble, and clean.
