Description

Technical Field

[0001] This utility model relates to the field of heating, ventilation and air conditioning technology, and in particular to an energy-saving heating, ventilation and air conditioning system. Background Technology

[0002] Heating, ventilation and air conditioning (HVAC) is a comprehensive technical system that integrates heating, ventilation and air conditioning functions. HVAC plays a vital role in modern buildings, dedicated to creating a comfortable, healthy and suitable indoor environment for people.

[0003] A search revealed Chinese Patent Publication No. CN218033437U, which discloses an energy-saving and environmentally friendly HVAC system belonging to the field of HVAC technology. The system includes an outdoor unit with two fixed frames fixed to it via several fixed plates. A micro motor is fixed to the top inner wall of each fixed frame, and a reciprocating lead screw is connected between the drive end of the micro motor and the fixed frame. Two guide rods are connected between the bottom inner walls of the fixed frames, and a cleaning rod is positioned between the guide rods and the reciprocating lead screw. Connecting posts are located at the top and bottom center of the cleaning rod, and movable blocks are rotatably connected to each connecting post. Gears are mounted on the connecting posts, and a toothed plate is located near the reciprocating lead screw on each fixed frame. This utility model, through the combined use of a fixed frame and a cleaning roller, can periodically clean the dust accumulated on the dustproof screen, avoiding affecting the normal use of the equipment. However, in actual use, because HVAC systems use a fan for active air intake, tiny particles in the air are attracted by the fan, making it easy for dust to penetrate and gradually accumulate on the inside of the dustproof screen. At this point, cleaning only the outside of the screen is not enough to clean it thoroughly, resulting in insufficient air intake for the dustproof screen to meet the needs of HVAC systems, reducing the practicality of the device and failing to meet the user's requirements. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an energy-saving HVAC system, which aims to improve the problem that it is not convenient to completely clean the filter screen in the existing energy-saving HVAC system.

A dust collection groove is opened at the bottom front side of the L-shaped plate. Springs are fixedly connected to the left and right sides of the rear wall of the L-shaped plate. The tops of the two springs are fixedly connected to the bottom left and right sides of the same driven bevel gear. A collection box is slidably connected to the bottom inner side of the window. A stop bar is fixedly connected to the top rear side of the collection box. A partition is fixedly connected to the middle inner side of the collection box.

[0009] The above technical solution allows for the collection of cleaned dust, ensuring that all dust enters the collection box, which can then be removed and the dust emptied.

[0010] As a further description of the above technical solution:

[0011] The window has sliding grooves on both the left and right sides of its bottom interior, and the collection box has sliders fixedly connected to both the left and right sides of its bottom. The interiors of the two sliding grooves are slidably connected to the corresponding sliders.

[0012] The above technical solution allows the collection box to slide inside the window, making it easy to take the collection box out.

[0013] As a further description of the above technical solution:

[0014] A handle is fixedly connected to the center of the front side of the collection box, and a rubber pad is fixedly connected to the outside of the handle.

[0015] The above technical solution allows staff to easily pull the collection box with a handle, and the rubber pad makes it more comfortable for staff to hold.

[0016] As a further description of the above technical solution:

[0017] The tops of the hollow block and the movable plate are both fixedly connected to protective shells, and the outer dimensions of the bristles match the dimensions of the dustproof net.

[0018] Through the above technical solution, the protective shell can be used to protect the threaded rod and the fixed rod on the front side, and the width of the brush bristles is consistent with the width of the dustproof net, so that every area of ​​the dustproof net is cleaned.

[0019] As a further description of the above technical solution:

[0020] The bottom of the air conditioner casing is fixedly connected to four sides with fixing plates, and the top of each fixing plate has a hole.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the motor drives the transmission rod to rotate, and when the transmission rod rotates, it drives two active bevel gears. Since the driven bevel gears mesh with the active bevel gears, the two driven bevel gears will drive the two threaded rods to rotate. At this time, the two movable plates will drive the brush bristles to move downwards, so that both sides of the dustproof net can be cleaned. This avoids the impact of reduced ventilation on the equipment, improves the practicality of the device, and can meet the needs of users.

[0030] 2. In this utility model, a dust collection groove is opened on the L-shaped plate. When the brush bristles clean the dustproof net, the dust will fall into the dust collection groove.

Detailed Implementation

[0039] 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.

[0040] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of an energy-saving HVAC system, comprising an air conditioner housing 1. A window 3 is provided on the front side of the air conditioner housing 1. A dustproof mesh 4 is fixedly connected to the upper inner side of the window 3. A hollow block 5 is fixedly connected to the bottom right end of the inner side of the window 3. A motor 6 is fixedly connected to the rear side of the hollow block 5. The output end of the motor 6 passes through the hollow block 5 and is fixedly connected to a transmission rod 7. A driving bevel gear 8 is fixedly connected to both the front and rear sides of the outer wall of the transmission rod 7. Threaded rods 9 are rotatably connected to both the front and rear sides of the top inner end of the hollow block 5. Driven bevel gears 10 are fixedly connected to the bottom ends of both threaded rods 9, and the two driven bevel gears 10 respectively mesh with the corresponding driving bevel gears 8. The top ends of the two threaded rods 9 pass through the hollow block 5. The top outer sides of the two threaded rods 9 are threaded with movable plates 11. The bottom left side of the inner side of the window 3 is fixedly connected to a fixed block 24. The top front and rear sides of the fixed block 24 are fixedly connected to fixed rods 12. The tops of the two fixed rods 12 pass through the corresponding movable plates 11. The adjacent sides of the two movable plates 11 are fixedly connected to bristles 13. The bottom of the rear movable plate 11 is provided with a collection mechanism 2. The collection mechanism 2 is used to facilitate the collection of dust. The tops of the hollow block 5 and the movable plate 11 are fixedly connected to a protective shell 18. The outer size of the bristles 13 matches the size of the dustproof net 4.

[0041] Specifically, during the cleaning and maintenance of the device, the motor 6 is started first. The start of the motor 6 drives the transmission rod 7 to rotate. During rotation, the transmission rod 7 further drives the two outer active bevel gears 8 to rotate synchronously. Since the driven bevel gears 10 mesh with the active bevel gears 8, when the active bevel gears 8 begin to rotate, the two driven bevel gears 10 also drive the two threaded rods 9 to rotate. Simultaneously, the left sides of the two movable plates 11 are limited by the fixed rods 12, and the movable plates 11 can only slide vertically up and down. Therefore, when the two threaded rods 9 begin to rotate, the movable plates 11 move downwards along the threaded rods 9. As the movable plates 11 move downwards, they also drive the brush bristles 13 downwards. The brush bristles 13 can clean both sides of the dustproof net 4. Since both the inner and outer sides of the dustproof net 4 are thoroughly cleaned, it ensures that the dustproof net 4 is completely clean, preventing dust accumulation on the dustproof net 4 from reducing ventilation and thus affecting the normal operation and efficiency of the equipment. This improves the practicality of the device and meets the needs of the user.

[0042] Reference Figure 2 , Figure 4 and Figure 6 The collection mechanism 2 includes a fixed plate 201, which is fixedly connected to the bottom left and right parts of the rear driven bevel gear 10. The two fixed plates 201 are rotatably connected to the same rotating rod 202 on adjacent sides. An L-shaped plate 203 is fixedly connected to the outside of the rotating rod 202. A dust collection groove 204 is opened at the bottom front side of the L-shaped plate 203. Springs 205 are fixedly connected to the left and right sides of the rear wall of the L-shaped plate 203. The tops of the two springs 205 are fixedly connected to the bottom left and right sides of the same driven bevel gear 10. A collection box 206 is slidably connected to the bottom inside of the window 3. A stop bar 207 is fixedly connected to the top rear side inside the collection box 206. A partition 208 is fixedly connected to the middle inside the collection box 206. A handle 16 is fixedly connected to the middle front side of the collection box 206. A rubber pad 17 is fixedly connected to the outside of the handle 16.

[0043] Specifically, during cleaning, a dust collection groove 204 is provided on the L-shaped plate 203 on the lower side of the movable plate 11. When the brush bristles 13 clean the dust screen 4, dust will fall into the dust collection groove 204. At the same time, the movable plate 11 will move the L-shaped plate 203 downwards during its movement. When the L-shaped plate 203 moves to the inside of the collection box 206, the rear bottom of the L-shaped plate 203 will contact the stop bar 207. Since the rotating rod 202 can rotate inside the two fixed plates 201, when the rear side of the L-shaped plate 203 is blocked by the stop bar 207, the L... As the L-shaped plate 203 continues to move downward, the rotating rod 202 will drive the L-shaped plate 203 to rotate, and the dust inside the dust collection trough 204 will fall into the collection box 206, so that the dust can be easily collected. When the L-shaped plate 203 rises, its rear side is pushed by the spring 205 and will rotate to a horizontal state. At this time, the staff only needs to pull the handle 16 to take out the collection box 206 and clean the collected dust. This design makes the cleaning work convenient and quick, greatly improves the cleaning efficiency, and reduces the workload of the staff.

[0044] Reference Figure 1 and Figure 2 The bottom left and right sides of the window 3 are provided with sliding grooves 14. The bottom left and right sides of the collection box 206 are fixedly connected with sliders 15. The interior of the two sliding grooves 14 are slidably connected to the corresponding sliders 15. The bottom four sides of the air conditioner housing 1 are fixedly connected with fixing pieces 19. The top of the multiple fixing pieces 19 are provided with holes 20.

[0045] Specifically, the collection box 206 can slide smoothly within the window 3 through the limiting action of the slide groove 14 and the slider 15. Multiple screws can be driven into the hole 20 at the top of the fixing piece 19 to fix it, thereby securing the device firmly.

[0046] Reference Figure 1 Fixed cones 21 are fixedly connected to the four corners of the top of the air conditioner housing 1. The top of each fixed cone 21 is rotatably connected to a hanging ring 22. A controller 23 is fixedly connected to the front of the top of the air conditioner housing 1. The controller 23 is electrically connected to the motor 6.

[0047] Specifically, the device can be easily hoisted using the lifting ring 22, and the controller 23 can control the operation of the motor 6, which is a miniature F130.

[0048] Working principle: When cleaning is required, motor 6 starts, which drives transmission rod 7 to rotate. When transmission rod 7 rotates, it drives the two outer active bevel gears 8 to rotate. Since driven bevel gears 10 mesh with active bevel gears 8, the two driven bevel gears 10 will drive the two threaded rods 9 to rotate. Since the left side of the two movable plates 11 is limited by fixed rods 12, the movable plates 11 can only slide up and down. When the two threaded rods 9 rotate, the two movable plates 11 will move downward. When the two movable plates 11 move downward, they will drive the bristles 13 to move downward. At this time, both sides of the dustproof net 4 can be cleaned. Cleaning both the inside and outside of the dustproof net 4 can completely clean the dustproof net 4 and avoid the impact of reduced ventilation on the equipment.

[0049] Furthermore, during cleaning, a dust collection groove 204 is provided on the L-shaped plate 203 on the lower side of the movable plate 11. When the brush bristles 13 clean the dustproof net 4, dust will fall into the dust collection groove 204. As the movable plate 11 moves, it will cause the L-shaped plate 203 to move downwards. When the L-shaped plate 203 moves to the inside of the collection box 206, the bottom rear side of the L-shaped plate 203 will contact the stop bar 207. Since the rotating rod 202 can rotate inside the two fixed plates 201, when the L-shaped plate 20... When the L-shaped plate 203 continues to move downwards due to the obstruction of the baffle 207 at the rear, the rotating rod 202 will drive the L-shaped plate 203 to rotate, and the dust inside the dust collection trough 204 will fall into the collection box 206, so that the dust can be easily collected. When the L-shaped plate 203 rises, its rear side will be pushed by the spring 205 and rotate to a horizontal state. The staff can then pull the handle 16 to take out the collection box 206 to clean the collected dust, which is convenient and quick.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
