Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and particularly to an air energy outdoor unit. Background Art

[0002] Air energy technology was initially mainly used in the refrigeration field. Its core principle is to convert the low-temperature heat energy in the air into high-temperature heat energy through components such as compressors, expansion valves, and evaporators, to achieve multi-functional energy utilization such as refrigeration and heating. Early technologies were limited by low energy efficiency and high costs, and their development was relatively slow. Nowadays, air conditioner units usually have strong refrigeration and heating capabilities and can adapt to different environmental requirements. The outdoor unit works outdoors for a long time, and in some harsh environments such as cold regions, the inside of the outdoor unit is easily affected by impurities in the air. The air conditioner filter protects the air conditioning equipment from pollutants; in the prior art, the air conditioner unit uses manual operation to manually disassemble and replace the filter screen. However, in the harsh outdoor environment, the workload of frequent replacement is also relatively large, which requires manpower and time.

[0003] The patent application document with the application publication number CN105928093A discloses an air conditioner outdoor unit, including a heat exchanger, an air conditioner outdoor unit frame, a fan, and an air volume adjustment device. The heat exchanger and the fan are located inside the air conditioner outdoor unit frame, and the fan is located at the top of the air conditioner outdoor unit frame. The air volume adjustment device includes an adjustment component and an installation component connected to the adjustment component. The installation component is installed on the air conditioner outdoor unit frame around the heat exchanger, and the adjustment component is used to adjust the air volume flowing through the heat exchanger generated by the fan, so that the air field flowing through the heat exchanger is more uniform, and it is realized that the air volume flowing through the heat exchanger can be adjusted by the adjustment component in the air volume adjustment device, so that the upper and lower air fields of the heat exchanger are evenly distributed.

[0004] In related technologies, in cold regions with poor outdoor environments and more rainy and snowy weather, snow is likely to accumulate on the air conditioner outdoor unit, blocking the filter screen of the air conditioner outdoor unit, resulting in poor air intake of the air conditioner outdoor unit, and causing the performance of the air conditioner to decline. When the temperature is relatively low, ice is likely to form on the air conditioner outdoor unit, which is difficult to quickly clean, resulting in the air conditioner being unable to be used normally. Moreover, the filter screen will be blocked after long-term use. In related technologies, when the filter screen is blocked, it is necessary to manually clean the filter screen, and the high-altitude outdoor environment increases the difficulty of cleaning the air conditioner outdoor unit. Summary of the Invention

[0005] The present invention provides an air energy outdoor unit, aiming to solve the problems in related technologies that snow is likely to accumulate on the air conditioner outdoor unit, blocking the filter screen of the air conditioner outdoor unit, resulting in poor air intake of the air conditioner outdoor unit, ice is likely to form on the air conditioner outdoor unit when the temperature is relatively low, and the filter screen will be blocked after long-term use, and it is difficult to quickly clean and restore the filter screen to normal.

Detailed Description of the Invention

[0032] The following describes in detail the embodiments of the present invention, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0033] As Figures 1 to 10 shown, an air - source outdoor unit includes a rear shell 1 and a filtering device provided on the rear shell 1. Providing the filtering device on the rear shell 1 enables the air entering the outdoor unit to be effectively filtered to prevent impurities in the air from entering the outdoor unit, affecting the normal operation and service life of the equipment.

[0034] The filtering device includes: a plurality of rotating plates 2, a winding assembly 3, a plurality of cleaning plates 4, a cleaning assembly 5 and a driving assembly. The plurality of rotating plates 2 are arranged at equal intervals left and right on the rear shell 1, and the rotating plates 2 are hinged to the rear shell 1. The plurality of cleaning plates 4 are arranged at the front ends of the rotating plates 2, and a gap for the filter screen 6 to pass through is formed between the rotating plates 2 and the cleaning plates 4. The filter screen 6 passes through the plurality of gaps in sequence. The winding assembly 3 adjusts the position of the filter screen 6 so that it can move along the gap. One end of the cleaning plate 4 in contact with the filter screen 6 can be telescopic, and it cooperates with the cleaning assembly 5 to clean the surface of the filter screen 6 when moving relative to the filter screen 6. The driving assembly drives the plurality of rotating plates 2 to rotate synchronously to achieve automatic cleaning of the filter screen 6. In the closed state, the cleaning plate 4 abuts against the adjacent rotating plate 2 to ensure the sealing of the rear shell 1, and the filter screen 6 is cleaned during the closing process to ensure that the filter screen 6 is sealed and protected to prevent impurities from accumulating on the filter screen 6. In the filtering state, the plurality of rotating plates 2 rotate so that the filter screen 6 between the adjacent rotating plates 2 is in the filtering state, and the outside air enters the unit interior after being filtered by the filter screen 6.

[0035] By setting the above device, the filter screen 6 can be automatically adjusted and cleaned, solving the problem of difficult cleaning of the filter screen 6 in harsh environments. Especially in cold regions, it can effectively prevent the filter screen 6 from being blocked and frozen, ensuring the normal use of the outdoor unit of the air conditioner.

[0036] As Figures 5 to 9 As shown, hinge columns 21 are arranged on both the upper and lower sides of the rotating plate 2. Installation frames 11 are provided on the rear shell 1, and hinge holes 12 are arranged on both the upper and lower sides of the installation frames 11. The hinge columns 21 cooperate with the hinge holes 12 to enable the rotating plate 2 to rotate towards the interior of the unit around the axis of the hinge holes 12, realizing the sealing and opening of the rear shell 1. A limit block 22 is arranged at the end of the rotating plate 2 far from the hinge column 21. The limit block 22 is arranged on the right end face of the rotating plate 2 in the up and down direction. When the plurality of rotating plates 2 are connected in sequence, the limit block 22 abuts against the adjacent rotating plate 2 to make the rear shell 1 in a sealed state. One end of the cleaning plate 4 far from the rotating shaft abuts against the adjacent rotating plate 2, and the filter screen 6 is received into the gap to seal the filter screen 6 for protection to prevent impurities from accumulating on the filter screen 6.

[0037] The hinge columns 21 can be made of metal materials to increase their strength and durability. The limit blocks 22 can be made of wear-resistant materials to extend their service life. The limit blocks 22 can be fixed by mechanical connection or welding methods to ensure the reliability and stability of the limit blocks 22 when the plurality of rotating plates 2 are connected in sequence.

[0038] As Figures 7 to 10As shown, the cleaning plate 4 includes a fixed plate 41 and a sliding plate 42. There is a gap for the filter screen 6 to pass through between the cleaning plate 4 and the rotating plate 2. The fixed plate 41 is arranged on the front side of the rotating plate 2 and is parallel to the rotating plate 2. The sliding plate 42 is slidably arranged within the fixed plate 41 and slides along the fixed plate 41 in the left - right direction. In the filtering state, the sliding plate 42 contracts along the fixed plate 41, shortening the length of the gap in the left - right direction and exposing the filter screen 6 originally located between the gaps, thus realizing the filtering function.

[0039] An elastic member is arranged between the fixed plate 41 and the sliding plate 42. The elastic member is preferably a spring, which has good elasticity and durability and can ensure that the sliding plate 42 maintains stable telescoping along the fixed plate 41 after long - term use. The sliding mode of the sliding plate 42 can be realized by setting guide rails or chutes, enabling the sliding plate 42 to slide smoothly within the fixed plate 41. The setting of the elastic member ensures that the sliding plate 42 can always maintain good contact with the filter screen 6 and can effectively clean during the movement of the filter screen 6. Through this structural design, the problem of poor contact between the filter screen 6 and the cleaning plate 4 during the cleaning process is solved.

[0040] As Figure 9 and Figure 10 As shown, the cleaning assembly 5 includes a scraping plate 51 and a collecting groove 52. The scraping plate 51 is arranged on the right side of the sliding plate 42 in the up - down direction and abuts against the filter screen 6 to ensure that the scraping plate 51 can effectively scrape off impurities. The collecting groove 52 is arranged on the sliding plate 42 and its opening is located on the right side of the scraping plate 51 so that impurities can smoothly enter the collecting groove 52. When the sliding plate 42 moves to the right along the filter screen 6, the scraping plate 51 is used to scrape off the impurities on the filter screen 6, and the collecting groove 52 is used to collect the scraped - off impurities.

[0041] The scraping plate 51 is arranged on the right side of the sliding plate 42 in the up - down direction to ensure that it can cover the entire surface of the filter screen 6, thus effectively scraping off all impurities. To further improve the cleaning effect, multiple scraping blades can be arranged on the scraping plate 51, and the collecting groove 52 can be designed as a detachable structure for convenient regular cleaning and maintenance.

[0042] The scraping plate 51 is inclined to the right in the front - back direction. Through this inclined setting method, the impurities on the filter screen 6 can be scraped off more effectively. The inclined scraping plate 51 can use its angle to more smoothly guide the impurities into the collecting groove 52, thereby improving the cleaning effect of the filter screen 6.

[0043] The inclined setting of the scraping plate 51 can be achieved in various ways. For example, the scraping plate 51 can be fixed on the sliding plate 42 through a hinge or a bracket, and the inclined purpose can be achieved by adjusting its fixing angle. As a preferred embodiment, the inclined angle of the scraping plate 51 can be adjusted according to the moving speed of the filter screen 6 and the type of impurities to achieve the best cleaning effect. In addition, the material of the scraping plate 51 can be selected from wear-resistant and corrosion-resistant metals or polymer materials to ensure its reliability during long-term use.

[0044] By setting the scraping plate 51 and the collection tank 52, an automated impurity cleaning process is realized, avoiding the tediousness and inconvenience of manual cleaning, being able to clean the impurities on the surface of the filter screen 6 more thoroughly, ensuring the normal operation of the outdoor air energy unit, and extending its service life.

[0045] As Figures 3 to 5 shown, two sealing plates 13 are provided on the rear end face of the rear shell 1. The two sealing plates 13 are respectively arranged on the upper and lower sides of the installation frame 11. The upper and lower end faces of the rotating plate 2 are respectively abutted against the two sealing plates 13. When the rotating plate 2 rotates backward, the sealing plates 13 keep the upper and lower sides of the rotating plate 2 sealed. Through the two sealing plates 13, the sealing state of the rear shell 1 during filtration can be ensured, thereby preventing external impurities from entering the unit interior and protecting the normal operation of internal components.

[0046] Furthermore, the two sealing plates 13 can be made of flexible materials to enhance the sealing effect. The sealing plates 13 can be fixed on the upper and lower sides of the installation frame 11 through screws or adhesives to ensure that they will not shift during use. Flexible gaskets can be provided on the upper and lower end faces of the rotating plate 2 to provide better sealing performance when contacting the sealing plates 13. A waterproof and dustproof coating can be applied on the surface of the sealing plates 13 to improve their durability and protection performance.

[0047] As Figures 5 to 8 shown, the driving assembly includes a driving source 71 and a synchronous belt 72. The synchronous belt 72 is installed on a plurality of articulated columns 21. The driving source 71 is installed on the rear shell 1. By driving the synchronous belt 72, a plurality of rotating plates 2 can rotate synchronously. The driving source 71 provides power. Through the transmission of the synchronous belt 72, all the rotating plates 2 can rotate synchronously, thus achieving the effect of synchronous rotation. This design ensures the synchronism of the rotating plates 2 and helps to improve the stability of the filtering device.

[0048] The driving source 71 is preferably a motor and a hydraulic driving device. The synchronous belt 72 can be a toothed belt or a flat belt. The articulated column 21 can be connected to the synchronous belt 72 through a bearing or other low-friction connection means to reduce the resistance and wear during operation. The driving source 71 precisely controls the running speed and direction of the synchronous belt 72 through a control system to ensure the synchronous rotation of multiple rotating plates 2. As a preferred embodiment, the driving source 71 can adjust the speed through a frequency converter to adapt to different working conditions and requirements. Through the design of the driving source 71 and the synchronous belt 72 in the driving assembly, the frequency of manual intervention is reduced, and it is applicable to various complex environmental conditions.

[0049] As Figures 5 to 8 shown, the winding assembly 3 includes a winding roller 31 and an unwinding roller 32. The winding roller 31 and the unwinding roller 32 are both rotatably arranged on the rear housing 1 in the up and down direction. The winding roller 31 and the unwinding roller 32 are respectively arranged at both ends of the mounting frame 11. Both ends of the filter screen 6 are respectively connected to the winding roller 31 and the unwinding roller 32. By providing the winding assembly 3, when the rear housing 1 is switched from the closed state to the filtering state, the movement of the filter screen 6 located in the gap can be adjusted, so that the filter screen 6 is wavy in the filtering state. After using for a period of time, the winding roller 31 and the unwinding roller 32 are used to replace the filtering part of the filter screen 6 in the filtering state and the part located in the gap. And after the filter screen 6 has been used for a long time, a new filter screen 6 of the unwinding assembly can be directly and quickly released to replace the original filter screen 6 located in the gap.

[0050] The winding roller 31 and the unwinding roller 32 can be rotated by a motor or other driving devices to automatically control the winding and unwinding processes of the filter screen 6. Both ends of the filter screen 6 are respectively fixed to the winding roller 31 and the unwinding roller 32. When the filter screen 6 needs to be replaced, the rotation of the winding roller 31 and the unwinding roller 32 can be controlled to replace the filter screen 6. This design solves the problem of difficult replacement of the filter screen 6 in the air energy outdoor unit and reduces the frequency and difficulty of manual operation.

[0051] As Figures 5 to 7 shown, a winding groove 33 and an unwinding groove 34 are provided on the rear housing 1. The winding groove 33 and the unwinding groove 34 are both arranged on the rear housing 1 in the up and down direction. The winding roller 31 is rotatably arranged in the winding groove 33, and the unwinding roller 32 is rotatably arranged in the unwinding groove 34. By providing the winding groove 33 and the unwinding groove 34 on the rear housing 1, the problem that the filter screen 6 on the winding roller 31 and the unwinding roller 32 is easily damaged in a harsh environment is solved.

[0052] The winding groove 33 and the unwinding groove 34 can be made of corrosion-resistant materials to ensure their durability under different environmental conditions. The rotation of the winding roller 31 and the unwinding roller 32 can be achieved by setting ball bearings to reduce friction and improve the flexibility of rotation. As a preferred embodiment, an automatic control device can also be set on the winding roller 31 and the unwinding roller 32 to detect the state of the filter screen 6 through a sensor and automatically control the winding and unwinding.

[0053] Working principle: When the equipment is working, the filter device arranged on the rear shell 1 is in the filtering state, the driving source 71 drives the synchronous belt 72 to rotate the multiple rotating plates 2 to the rear side, and the upper and lower side surfaces of the rotating plate 2 move along the sealing plate 13, and the filter screen 6 causes the abutting sliding plate 42 to shrink along the fixed plate 41, and the filter screen 6 located between the sliding plate 42 and the rotating plate 2 filters the air entering the unit. After the filter screen 6 is blocked after filtering for a period of time, the driving source 71 causes the multiple rotating plates 2 to rotate to the front side, and the scraper 51 moves along the filter screen 6 to scrape off the impurities on the filter screen 6. The inclined scraper 51 guides the impurities into the collecting tank 52. When the limit block 22 abuts on the adjacent rotating plate 2, the driving source 71 stops, and the scraper 51 completes the cleaning of the impurities on the surface of the filter screen 6. The sliding plate 42 abuts on the adjacent rotating plate 2, and the rear shell 1 When the filter 6 is in a closed state, the sliding plate 42 prevents the filter 6 in the gap from contacting the outside world, which can prevent snow or frost from accumulating on the surface of the filter 6 when the weather is bad, causing the outdoor unit to malfunction. When working in a bad environment, when impurities accumulate on the filter 6, the scraper 51 cleans the filter 6, so that the filter 6 can quickly return to normal state. After a period of use, when the filtering effect of the filter 6 between the sliding plate 42 and the rotating plate 2 deteriorates, the winding roller 31 and the unwinding roller 32 cooperate to replace the filter 6 between the sliding plate 42 and the rotating plate 2 with the filter 6 in the gap. After long-term use, when the filter 6 cannot filter normally, the winding roller 31 and the unwinding roller 32 cooperate to replace the filter 6 in the gap with the new filter 6 on the unwinding roller 32, and rewind the filter 6 in the original gap onto the winding roller 31.

[0054] Filter components can be set on multiple surfaces of the rear shell 1, so that the unit can maintain a good filtering effect in different environments, reducing equipment failure and performance degradation caused by impurity accumulation. The rear shell 1 and the filter component structure can be applied to a variety of air-conditioning outdoor units or outdoor units of trigeneration heat pump units, etc.

[0055] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
