Description

Technical Field

[0001] This utility model relates to the technical field of air conditioner evaporators, and in particular to an air conditioner evaporator that is easy to clean. Background Technology

[0002] The air conditioner evaporator is one of the core components of the air conditioning refrigeration system. It plays a vital role in the entire air conditioning operation and is the key link to achieve the cooling effect. Structurally, the air conditioner evaporator is usually composed of a series of neatly arranged metal tubes and heat sinks. These metal tubes are generally made of copper tubes with good thermal conductivity, while the heat sinks are mostly made of aluminum. The heat sinks are tightly fixed to the metal tubes through a specific process to increase the heat exchange area.

[0003] Chinese patent website discloses an evaporator that is easy to clean, publication number: CN207785963U. It includes an evaporator shell, evaporation fins, a water outlet, and a water inlet. A load-bearing bracket is welded and fixed to the bottom of the evaporator shell. A cleaning brush is installed at the bottom of the load-bearing bracket, and a fixing plate is fixed above the cleaning brush. A screw lever is fixed to one side of a servo motor via a rotating shaft. The other end of the evaporation tube passes through the interior of the evaporation fins and is fixedly connected to the water inlet. By designing a cleaning brush installed on the outside of the evaporator, dust on the surface of the evaporation fins is cleaned, greatly reducing dust accumulation. Since evaporators are generally designed to be installed inside machines, they cannot be accessed manually at all times. By designing a servo motor installed at the bottom of the cleaning brush and a screw lever installed at one end of the motor, automatic cleaning of the cleaning brush is achieved, greatly reducing the difficulty of cleaning and solving the problem of difficult-to-clean evaporators.

[0004] The solution also has the following problems: the solution only uses a lead screw to drive the cleaning brush to clean the dust on the fins, but the dust is still inside the evaporator after cleaning, and the dust will be dispersed in the internal space of the evaporator when the cleaning brush is used. After settling, there is still a lot of dust, so the cleaning effect is poor and there are certain drawbacks.

[0005] Therefore, in order to solve the above problems, this utility model provides an air conditioner evaporator that is easy to clean. Utility Model Content

[0006] The purpose of this invention is to provide an air conditioner evaporator that is easy to clean, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an air conditioner evaporator that is easy to clean, comprising an evaporator body, wherein several sets of fins are installed inside the evaporator body, and fixing ears are symmetrically installed at both ends of the top of the evaporator body. A threaded rod is installed between the outer surfaces of the fixing ears, and two connected movable blocks are installed on the outer ring surface of the threaded rod at the top of the evaporator body. A first connecting rod is installed at one end of the outer surface of the movable blocks, and a support frame is installed at the end of the first connecting rod away from the movable blocks. Several fixing seats are installed at equal intervals on the outer surface of the support frame, and an outer toothed ring is installed at one end of the outer ring surface of the fixing seats. An annular cleaning brush is installed on one side of the outer toothed ring.

[0008] Preferably, a servo motor is mounted on the outside of one of the fixed ears. The output shaft of the servo motor passes through the fixed ear and is connected to one end of the threaded rod. The outer ring surface of the threaded rod is threadedly connected to the inside of the movable block. The bottom of the movable block is in contact with the top of the evaporator body. The two movable blocks are arranged in a mirror image.

[0009] Preferably, a second connecting rod is installed at the end of the movable block away from the first connecting rod, an air pump is installed at the end of the second connecting rod away from the movable block, an air supply pipe is installed at the bottom end of the second connecting rod, and a plurality of nozzles are installed at equal intervals in a vertical distribution on the outer ring surface of the air supply pipe.

[0010] Preferably, a drive gear is installed on the outer side of the support frame and below the first connecting rod, and a drive motor is installed on the outer side of the support frame away from the drive gear. The output shaft of the drive motor passes through the support frame and is connected to the drive gear.

[0011] Preferably, the plurality of external gear rings mesh with each other, the drive gear meshes with the uppermost external gear ring, the outer ring surface of the fixed seat is rotatably connected to the inner sidewall of the external gear ring, and one end of the annular cleaning brush is in contact with the outside of the fins.

[0012] Preferably, a plurality of vacuum heads are mounted in a circular array at one end of the fixed base and inside the annular cleaning brush. A vacuum cleaner is mounted on the outer side of the support frame away from the fixed base. A connecting tube is installed on the output end of the vacuum cleaner, extending into the multiple fixed bases and connecting to the multiple vacuum heads on the outside.

[0013] In summary, this utility model has the following beneficial technical effects:

[0014] This easy-to-clean air conditioner evaporator uses an air pump to compress outside air and deliver it to various nozzles via an air supply pipe. The nozzles spray air to blow off dust and debris adhering to the sides of the fins, assisting the annular cleaning brush in completing the cleaning work more effectively. When the drive gear rotates, it meshes with the uppermost outer gear ring, causing the uppermost outer gear ring to rotate. Because multiple outer gear rings mesh with each other, they rotate sequentially. The outer gear rings drive the annular cleaning brush to rotate and clean the surface of the fins, effectively removing dust and dirt. During the cleaning process of the annular cleaning brush on both sides of the fins, dust and debris are generated. At this time, the vacuum cleaner generates suction, which is transmitted to each suction head through a connecting pipe. The suction head sucks in the dust and debris cleaned by the annular cleaning brush and transports it to the vacuum cleaner for collection through the connecting pipe. This achieves the goal of blowing away dust on both sides of the fins before cleaning and vacuuming, preventing dust and debris from re-adhering to the fins or scattering in the surrounding environment, ensuring cleaning effect and environmental cleanliness. It is easy to operate and has better practicality. Attached Figure Description

[0021] The following is in conjunction with the appendix Figure 1 - Figure 5 The present invention will be described in further detail below.

[0022] An easy-to-clean air conditioner evaporator, see reference. Figure 1 - Figure 5 The evaporator body 1 includes several sets of fins 2 installed inside the evaporator body 1. Fixed ears 3 are symmetrically installed at both ends of the top of the evaporator body 1. Threaded rods 4 are installed between the outer sides of the fixed ears 3. Two connected movable blocks 5 are installed on the outer ring surface of the threaded rods 4 and at the top of the evaporator body 1. A first connecting rod 6 is installed at one end of the outer side of the movable block 5. A support frame 7 is installed at the end of the first connecting rod 6 away from the movable block 5. Several fixed seats 8 are installed at equal intervals on the outer side of the support frame 7. An outer toothed ring 9 is installed at one end of the outer ring surface of the fixed seat 8. An annular cleaning brush 10 is installed on one side of the outer toothed ring 9.

[0023] Reference Figure 1 - Figure 3 One of the fixed ears 3 has a servo motor 11 mounted on its exterior. The output shaft of the servo motor 11 passes through the fixed ear 3 and connects to one end of the threaded rod 4. The outer ring of the threaded rod 4 is threadedly connected to the interior of the movable block 5, and the bottom of the movable block 5 is in contact with the top of the evaporator body 1. The two movable blocks 5 are mirror images of each other. When the servo motor 11 is started, its output shaft drives the threaded rod 4 to rotate. Because the threaded rod 4 is threadedly connected to the movable block 5 and the bottom of the movable block 5 is in contact with the top of the evaporator body 1, the rotation of the movable block 5 is restricted. The movable block 5 will then reciprocate in a straight line along the threaded rod 4. A second connecting rod 12 is mounted on the end of the movable block 5 away from the first connecting rod 6. An air pump 13 is installed at the end of the second connecting rod 12 away from the movable block 5. An air supply pipe 14 is installed at the bottom end of the second connecting rod 12. Several nozzles 15 are installed at equal intervals on the outer ring surface of the air supply pipe 14. When the air pump 13 is working, it compresses the outside air and delivers it to each nozzle 15 through the air supply pipe 14. The nozzles 15 spray the compressed air at a certain speed and angle to form an airflow. Since the movable block 5 moves under the drive of the servo motor 11, the airflow sprayed by the nozzles 15 can simultaneously blow and clean the two sides of the fin 2 along with the movement of the movable block 5, blowing off some dust and debris attached to the two sides of the fin 2, and assisting the annular cleaning brush 10 to better complete the cleaning work.

[0024] Reference Figure 1 - Figure 5An active gear 16 is installed on the outer side of the support frame 7 and below the first connecting rod 6. A drive motor 17 is installed on the outer side of the support frame 7 away from the active gear 16. The output shaft of the drive motor 17 passes through the support frame 7 and is connected to the active gear 16. After the drive motor 17 is started, its output shaft drives the active gear 16 to rotate. Multiple outer gear rings 9 mesh with each other. The active gear 16 meshes with the uppermost outer gear ring 9. The outer ring surface of the fixed seat 8 is rotatably connected to the inner side wall of the outer gear ring 9. One end of the annular cleaning brush 10 is in contact with the outer side of the fin 2. When the active gear 16 rotates, it will drive the uppermost outer gear ring 9 to rotate because the active gear 16 meshes with the uppermost outer gear ring 9. Since multiple outer gear rings 9 mesh with each other, each outer gear ring 9 will rotate in sequence. The outer gear ring 9 drives the annular cleaning brush 10 to rotate. The annular cleaning brush 10 is in contact with the two sides of the fin 2. During the rotation, it cleans the two sides of the fin 2, effectively removing dust and dirt.

[0025] Reference Figure 3 - Figure 5 A number of vacuum heads 18 are installed in a circular array at one end of the fixed base 8 and inside the annular cleaning brush 10. A vacuum cleaner 19 is installed on the outer side of the support frame 7 away from the fixed base 8. A connecting pipe 20 is installed on the output end of the vacuum cleaner 19, extending into the multiple fixed bases 8 and connecting to the multiple vacuum heads 18 on the outside. During the cleaning of the fins 2 by the annular cleaning brush 10, dust and debris are generated. At this time, the vacuum cleaner 19 works to generate suction, which is transmitted to each vacuum head 18 through the connecting pipe 20. The vacuum head 18 sucks in the dust and debris cleaned by the annular cleaning brush 10 and transports it to the inside of the vacuum cleaner 19 through the connecting pipe 20 for collection, so as to prevent dust and debris from adhering to the sides of the fins 2 or scattering in the surrounding environment, thus ensuring the cleaning effect and the cleanliness of the environment.

[0026] The implementation principle of this utility model embodiment of an easy-to-clean air conditioner evaporator is as follows: When the air conditioner evaporator needs to be cleaned, the air pump 13 compresses the outside air and delivers it to each nozzle 15 through the air supply pipe 14. The nozzle 15 sprays the compressed air at a certain speed and angle to form an airflow, blowing off some dust and debris attached to both sides of the fins 2, assisting the annular cleaning brush 10 to better complete the cleaning work. After the drive motor 17 starts, its output shaft drives the drive gear 16 to rotate. When the drive gear 16 rotates, it meshes with the uppermost outer gear ring 9, which in turn drives the uppermost outer gear ring 9 to rotate. Since multiple outer gear rings 9 mesh with each other, each outer gear ring 9 will rotate in sequence. The outer gear rings 9 drive the annular cleaning brush 10 to rotate. The annular cleaning brush 10 is in contact with the surfaces of both sides of the fins 2, cleaning the surface of the fins 2 during rotation, effectively removing dust and dirt. During the cleaning process of the annular cleaning brush 10, dust and debris are generated. At this time, the vacuum cleaner 19 works to generate suction. The suction power is transmitted to each suction head 18 through the connecting pipe 20. The suction head 18 sucks in the dust and debris cleaned by the annular cleaning brush 10 and transports it to the inside of the vacuum cleaner 19 through the connecting pipe 20 for collection. This prevents the dust and debris from re-adhering to the fins 2 or scattering in the surrounding environment, ensuring cleaning effect and environmental cleanliness. When the servo motor 11 is started, its output shaft drives the threaded rod 4 to rotate. Since the threaded rod 4 is threadedly connected to the movable block 5 and the bottom of the movable block 5 is attached to the top of the evaporator body 1, restricting the rotation of the movable block 5, the movable block 5 will move back and forth in a straight line along the threaded rod 4. Since the movable block 5 moves under the drive of the servo motor 11 and the two movable blocks 5 are set in a mirror image, the airflow sprayed by the nozzle 15 can sweep the two sides of the fins 2 with the movement of the two movable blocks 5, and at the same time drive multiple annular cleaning brushes 10 to clean synchronously. This facilitates the reciprocating cleaning of the outer sides of the fins 2, realizing the blowing and cleaning of dust on both sides of the fins 2. The operation is convenient and the practicality is better.
