Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically a low-temperature air conditioning defrosting structure based on fresh air energy recovery. Background Technology

[0002] An air conditioning unit is an integrated device that can regulate air temperature, humidity, cleanliness, and airflow speed. It uses refrigerant circulation to achieve cooling or heating through core components such as compressors, condensers, and evaporators. With the help of fans, it circulates air. Some units also have air filtration functions to remove dust and other impurities. Air conditioning units are widely used in shopping malls, office buildings, factories, and other places to create a comfortable and healthy indoor environment for people and meet the diverse air conditions required in different scenarios.

[0003] In low-temperature environments, the defrosting problem of air conditioning units has always been a key factor restricting their efficient operation. Traditional low-temperature air conditioning defrosting processes generally suffer from low defrosting efficiency and high energy consumption. Most defrosting methods use electric heating or shutdown defrosting, which not only consumes a lot of electricity but also causes large fluctuations in indoor temperature, affecting user comfort and environmental stability. On the other hand, during the defrosting process, air conditioning units cannot effectively utilize external natural energy, especially the energy contained in fresh air, resulting in energy waste. Utility Model Content

[0004] The purpose of this invention is to provide a low-temperature air conditioning defrosting structure based on fresh air energy recovery to solve the problems mentioned in the background art.

[0015] This invention provides a low-temperature air conditioning defrosting structure based on fresh air energy recovery. It has the following beneficial effects:

[0016] (1) When the air conditioning unit is defrosting, the present invention can be held and pulled outward. The pull rod slides on the inner wall of the sliding hole, and at the same time, one end of the pull rod rotates on the side of the connecting block, so that the pull rod drives the connecting block to move. The connecting block drives the rotating plate to rotate on the side of the fixed block.

[0017] (2) This utility model starts the blower, which draws outside air into the ventilation pipe. The air is filtered by the filter screen to prevent impurities from entering the ventilation pipe. The air then passes through the ventilation pipe and the connecting component to enter the air conditioning unit. When it is necessary to clean the filter screen, you can hold the handle and pull it up and down. The handle moves the filter screen up and down through the connecting rod. The filter screen slides on the inner wall of the slide rail. At the same time, the cleaning brush that is in contact with the filter screen will brush off the impurities on the filter screen as the filter screen moves up and down. The collected box can be used to collect the brushed-off impurities, thus achieving the effect of filtering the air. Attached Figure Description

[0025] 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.

[0026] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] Example 1

[0028] A preferred embodiment of the low-temperature air conditioning defrosting structure based on fresh air energy recovery provided by this utility model is, for example... Figure 1-4 As shown: A low-temperature air conditioning defrosting structure based on fresh air energy recovery includes an air conditioning unit 1, a connecting pipe 2 connected to one side of the air conditioning unit 1, a filter assembly 3 provided on the upper surface of the air conditioning unit 1, and a connecting assembly 4 provided on one side of the filter assembly 3.

[0029] The filter assembly 3 includes a ventilation duct 311, which is fixedly connected to the upper surface of the air conditioning unit 1. A slide rail 313 is provided at one end of the ventilation duct 311, which is fixedly connected to one end of the ventilation duct 311. A filter screen 314 is provided on the inner wall of the slide rail 313, and the filter screen 314 is slidably connected to the inner wall of the slide rail 313.

[0030] The connecting component 4 includes a fixing block 413, which is fixedly connected to the upper surface of the air conditioning unit 1. A rotating plate 414 is provided on one side of the fixing block 413, and the rotating plate 414 is rotatably connected to the fixing block 413 through a bearing seat. A pad 417 is provided at the bottom of the rotating plate 414, and the pad 417 is fixedly connected to the bottom of the rotating plate 414. The filter component 3 also includes a blower 312, which is fixedly installed on the upper surface of the air conditioning unit 1. A connection hole is opened on one side of the ventilation pipe 311. The filter screen 314 is adapted to the connection hole; a connecting rod 315 is provided on the upper surface of the filter screen 314, the connecting rod 315 is fixedly connected to the upper surface of the filter screen 314, a handle 316 is provided on the upper surface of the connecting rod 315, the handle 316 is fixedly connected to the upper surface of the connecting rod 315, a fixing rod 317 is provided on one side of the slide rail 313, the fixing rod 317 is fixedly connected to one side of the fixing rod 317, and the cleaning brush 318 is adapted to the filter screen 314;

[0031] Furthermore, in this embodiment, when the air conditioning unit 1 enters the defrosting program, the air conditioning unit 1 itself starts defrosting. Alternatively, the pull rod 416 can be manually held and pulled outward to slide along the inner wall of the sliding hole of the fixed plate 412. During this process, one end of the pull rod 416 rotates around the connecting block 415 as a fulcrum, converting the linear pull into a circular motion driving force, which in turn drives the connecting block 415 to move. The connecting block 415 is fixedly connected to the rotating plate 414, thus synchronously driving the rotating plate 414 to rotate around the fixed block 413. As the rotating plate 414 rotates, the pad 417 at its bottom rotates accordingly, thereby opening the air inlet on the upper surface of the air conditioning unit 1. The rotation of the pad 417 simultaneously drives the fixed plate 418 and the limiting rod 419 to rotate synchronously until the top of the limiting rod 419 abuts against the top of the inner wall of the air conditioning unit 1. At this time, external air can smoothly enter the interior of the air conditioning unit 1, and the defrosting operation is completed by accelerating the melting of the frost layer through air convection.

[0032] Example 2

[0033] Based on Example 1, a preferred embodiment of the low-temperature air conditioning defrosting structure based on fresh air energy recovery provided by this utility model is as follows: Figure 1-4 As shown: The connecting component 4 also includes a fixing frame 411, which is fixedly connected to the upper surface of the air conditioning unit 1. The fixing frame 411 is fixedly connected to the other end of the ventilation duct 311. A fixing plate 412 is provided on one side of the fixing frame 411. The fixing plate 412 is fixedly connected to one side of the fixing frame 411. A sliding hole is provided on one side of the fixing plate 412. A connecting block 415 is provided on the upper surface of the rotating plate 414. The connecting block 415 is fixedly connected to the upper surface of the rotating plate 414. A pull rod 416 is provided on one side of 415. The pull rod 416 is rotatably connected to the connecting block 415 through a bearing seat. The pull rod 416 is slidably connected to the inner wall of the sliding hole. An air inlet is provided on the upper surface of the air conditioning unit 1. The pad 417 is adapted to the air inlet. A second fixing plate 418 is provided at the bottom of the pad 417. The second fixing plate 418 is fixedly connected to the bottom of the pad 417. A limit rod 419 is provided on the other side of the second fixing plate 418. The limit rod 419 is fixedly connected to the other side of the second fixing plate 418.

[0034] Furthermore, in this embodiment, after the blower 312 is turned on, it immediately initiates an air extraction procedure, continuously drawing external air into the ventilation duct 311. During the process of entering the ventilation duct 311, the air first undergoes strict filtration through the filter screen 314. This filter screen acts as a protective barrier, effectively intercepting dust, particles, and other impurities, preventing them from entering the ventilation duct 311 and ensuring the cleanliness of the air transported. The filtered air continues to flow along the ventilation duct 311, passes through the connecting component 4, and finally enters the air conditioning unit 1. After long-term use, if... When filter screen 314 becomes full of impurities and needs cleaning, the operator can directly hold handle 316 and pull it up and down. Handle 316 is connected to filter screen 314 through connecting rod 315, so it can drive filter screen 314 to slide up and down along the inner wall of slide rail 313. It is worth mentioning that cleaning brush 318 is in close contact with filter screen 314. When filter screen 314 slides, cleaning brush 318 will perform deep cleaning on its surface, brushing off the attached impurities one by one. At this time, simply place a collection box below to easily catch the brushed impurities, realizing convenient cleaning of filter screen 314.

[0035] In use, when the air conditioning unit 1 first enters the defrosting program, the air conditioning unit 1 automatically starts defrosting. Alternatively, the pull rod 416 can be manually held and pulled outwards, causing it to slide along the inner wall of the sliding hole in the fixed plate 412. During this process, one end of the pull rod 416 rotates around the connecting block 415 as a fulcrum, converting the linear pull into a circular motion driving force, which in turn causes the connecting block 415 to move. The connecting block 415 is fixedly connected to the rotating plate 414, thus synchronously driving the rotating plate 414 to rotate around the fixed plate. As block 413 rotates, the bottom pad 417 rotates along with the rotating plate 414, thereby opening the air inlet on the upper surface of the air conditioning unit 1. The rotation of the pad 417 simultaneously drives the fixing plate 418 and the limiting rod 419 to rotate synchronously until the top of the limiting rod 419 abuts against the top of the inner wall of the air conditioning unit 1. At this time, after the blower 312 is turned on, it immediately starts the air extraction program, continuously drawing external air into the ventilation pipe 311. During the process of the air entering the ventilation pipe 311, the air will first... After rigorous filtration by filter 314, this filter acts as a protective barrier, effectively intercepting dust, particles, and other impurities to prevent them from entering the ventilation duct 311 and ensuring the cleanliness of the air supply. The filtered air continues to flow along the ventilation duct 311, passes through the connecting component 4, and then allows outside air to smoothly enter the air conditioning unit 1. Through air convection, the frost layer melts faster, completing the defrosting process. After long-term use, if filter 314 becomes full of impurities and needs cleaning, the operator can directly grasp the handle 316 and pull it up and down. The handle 316 is connected to filter 314 via connecting rod 315, thus allowing filter 314 to slide up and down along the inner wall of slide rail 313. It is worth mentioning that the cleaning brush 318 fits tightly against filter 314. When filter 314 slides, the cleaning brush 318 performs a deep cleaning of its surface, brushing off the attached impurities one by one. At this time, simply place a collection box below to easily catch the brushed-off impurities, achieving convenient cleaning of filter 314.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
