A multi-layer split-flow rainproof device for the fresh air inlet of an air conditioning unit

Abstract

This utility model discloses a multi-layer diversion type rainproof device for the fresh air inlet of an air conditioning unit, relating to the field of air conditioning technology. It includes two side plates, with multiple layered partitions installed between them. Each layered partition is sloped towards the air inlet side. In use, the sloped partitions effectively trap fine water particles, allowing them to flow downwards and exit from the device from the left and right, ensuring that rainwater does not enter the air conditioning unit. Furthermore, the dual-direction air inlet structure, with upper and lower insect-proof net components at each inlet, provides protection against sand, insects, animals, and rain. When rainwater comes into contact with the upper and lower insect-proof net components, most of it is intercepted and does not enter the air conditioning unit. The device is compact, occupies little space, and has high mechanical strength, making it particularly suitable for air conditioning units with large fresh air volumes.

Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a multi-layer diversion type rainproof device for the fresh air inlet of an air conditioning unit. Background Technology

[0002] In the field of air conditioning units, when air conditioning units are installed outdoors, the suitability of the rain protection measures for the fresh air inlet is crucial to the unit's operational reliability. An inadequate design can allow rainwater to enter the unit, affecting the filtration efficiency and lifespan of the unit's filters, and accelerating corrosion. Furthermore, since the fresh air inlet of the air conditioning unit is directly exposed to the atmosphere, without proper protection, it is difficult to prevent dust, insects, animals, and other contaminants from entering the unit. Such contamination can range from affecting air quality to seriously impacting the product quality of the customers. Therefore, reliable measures are essential.

[0003] Existing traditional rainproofing methods have problems such as large space occupation, high wind speed, insufficient strength, and poor rain and insect protection performance. In view of this, this application proposes a multi-layer diversion type rainproofing device for the fresh air inlet of an air conditioning unit. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a multi-layer diversion type rainproof device for the fresh air inlet of an air conditioning unit.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-layer diversion rainproof device for the fresh air inlet of an air conditioning unit includes two side plates, with multiple layered partitions installed between the two side plates. Each layered partition is sloped towards the air inlet side. Multiple reinforcing beams are installed on the outer sides of the multiple layered partitions. A second crossbeam and a first crossbeam are installed on the bottom sides of the two side plates, respectively, and the bottom end of each reinforcing beam is fixedly connected to the top surface of the first crossbeam. A third crossbeam is installed on the sides of the two side plates. An upper insect-proof net assembly is installed on the outer sides of the two side plates, and a lower insect-proof net assembly is installed on the bottom ends of the two side plates.

[0007] Preferably, each of the upper and lower insect-proof net components includes two support beams and two longitudinal beams, and the two support beams and two longitudinal beams together form a frame. A pressure strip is installed between each pair of support beams, and a wire mesh is installed on the outer side of each support beam and pressure strip.

[0008] Preferably, the side plate is formed from steel and is connected to the first crossbeam, the layered partition, the second crossbeam, and the third crossbeam by bolts.

[0009] Preferably, each of the reinforcing beams 7 is formed from steel and is located on the outer end face of multiple layered partitions, and the spacing between any two reinforcing beams is 400 to 450 mm.

[0010] Preferably, each pair of support beams is fixedly connected to the corresponding longitudinal beam by a plurality of steel rivets.

[0011] This utility model has the following beneficial effects:

[0012] 1. This utility model, through devices such as layered partitions, upper insect-proof net components, and lower insect-proof net components, achieves a layered partition design with a slope facing the air inlet side, which can effectively block fine water particles and allow them to flow downwards and then out of the device from the left and right directions, ensuring that rainwater does not enter the air conditioning unit. Furthermore, through the dual-direction air inlet structure, upper and lower insect-proof net components are respectively set at the two air inlets, which can not only prevent sand, insects, and animals, but also prevent rain. When rainwater comes into contact with the upper and lower insect-proof net components, most of it will be intercepted and will not enter the air conditioning unit.

[0013] 2. This utility model achieves an overall sloping design through side panels and other devices, thus avoiding the problems of water, snow, and dust accumulation on the top when the volume is large.

[0014] 3. This utility model achieves the stability of layered plate installation through side plates, reinforcing beams and other devices. The device has a compact structure, occupies little space, and has high mechanical strength, making it particularly suitable for air conditioning units with large fresh air volume.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] This utility model provides a technical solution: such as Figure 1-5 As shown, a multi-layer diversion rainproof device for the fresh air inlet of an air conditioning unit includes two side plates 1. Multiple layered partitions 3 are installed between the two side plates 1. The slope of each layered partition 3 is designed to be inclined towards the air inlet side to facilitate the diversion of rainwater to the outside. Multiple reinforcing beams 7 are installed on the outside of the multiple layered partitions 3 to enhance the installation stability of the layered partitions 3. A second crossbeam 4 and a first crossbeam 2 are installed on the bottom of the sides of the two side plates 1 respectively, and the bottom end of each reinforcing beam 7 is fixedly connected to the top surface of the first crossbeam 2. A third crossbeam 5 is installed on the sides of the two side plates 1. An upper insect-proof net assembly 6 is installed on the outside of the two side plates 1. A lower insect-proof net assembly 8 is installed on the bottom of the two side plates 1.

[0023] The device is equipped with an upper insect-proof net assembly 6 and a lower insect-proof net assembly 8 at its bottom and sides, respectively. It adopts a two-way air intake structure, which can effectively reduce air flow speed and wind resistance. It can also prevent sand, insects, and animals, as well as rain. When rainwater comes into contact with the upper insect-proof net assembly 6 or the lower insect-proof net assembly 8, most of it will be intercepted and will not enter the air conditioning unit.

[0024] Furthermore, each upper insect-proof net assembly 6 and lower insect-proof net assembly 8 includes two support beams 10 and two longitudinal beams 9, and the two support beams 10 and the two longitudinal beams 9 together form a frame. A pressure strip 12 is installed between each pair of support beams 10, and a wire mesh 11 is installed on the outside of each support beam 10 and pressure strip 12. The wire mesh 11 is fixed and pressed by the pressure strip 12.

[0025] Furthermore, the side plate 1 is made of steel and is connected to the first crossbeam 2, the layered partition plate 3, the second crossbeam 4, and the third crossbeam 5 by bolts.

[0026] Furthermore, each reinforcing beam 7 is made of steel and is located on the outer end face of multiple layered partitions 3, with a spacing of 400 to 450 mm between every two reinforcing beams 7.

[0027] Furthermore, each pair of support beams 10 is fixedly connected to the corresponding longitudinal beam 9 by a plurality of steel rivets 13.

[0028] This utility model provides a multi-layer diversion type rainproof device for the fresh air inlet of an air conditioning unit. The specific working principle is as follows: The main body of the device is composed of a frame made of symmetrical steel side plates 1. Multiple layered partitions 3 inclined towards the air inlet side are set between the side plates 1 to divert rainwater outward by using the slope.

[0029] The outer side of the layered partition 3 is fixedly connected to the bottom first crossbeam 2 by the reinforcing beam 7 with a spacing of 400~450mm to form a stable support. The first crossbeam 2 is set at the front edge of the air inlet side, and the second crossbeam 4 and the third crossbeam 5 are installed at the top and bottom of the air outlet side respectively, and are bolted to the air inlet flange of the air conditioning unit.

[0030] Furthermore, the bottom and sides of the device are respectively equipped with upper insect-proof net assembly 6 and lower insect-proof net assembly 8 to form a two-way air intake structure. Both upper insect-proof net assembly 6 and lower insect-proof net assembly 8 are composed of a frame consisting of support beam 10 and longitudinal beam 9. The wire mesh 11 is pressed by pressure strip 12 and fixed with steel rivets 13 to form a multi-layer interception barrier. When air carrying rainwater or foreign objects enters, the two-way air intake design reduces the flow velocity and disperses the airflow. The inclined layered partition 3 guides the rainwater to drain out. At the same time, the wire mesh 11 intercepts insects, sand and most of the rainwater. The remaining water droplets slide down along the layered partition 3 under the action of gravity. Finally, the air enters the unit smoothly after being diverted, achieving a synergistic effect of high-efficiency protection and low wind resistance operation.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
