Description

Technical Field

[0001] This utility model relates to the field of air conditioning duct technology, and in particular to a heating, ventilation and air conditioning duct structure that is easy to clean. Background Technology

[0002] HVAC ducts are an important component of HVAC systems, undertaking the critical task of transporting media such as air and refrigerant. They are usually made of metal or non-metal materials and have good corrosion resistance and sealing properties. The reasonable layout and design of the duct system directly affects the operating efficiency and energy consumption of the HVAC system. During installation, the routing must be precisely planned to ensure smooth airflow.

[0003] Existing technologies, such as the utility model with publication number CN215412427U, relate to the field of HVAC (Heating, Ventilation, and Air Conditioning), specifically a crack-resistant pipe for HVAC systems. It includes two ventilation pipes, two first fixing components, and two second fixing components. The first and second fixing components are respectively fixedly connected to both ends of the ventilation pipes, with one end of the first fixing component fixedly connected to the second fixing component. This utility model, by setting up the second fixing component, allows glue to enter and fill the gap between the first and second fixing frames along the liquid guide groove after the bolt punctures the liquid storage bag, increasing the sealing between the two ventilation pipes. Simultaneously, when the bolt punctures the liquid storage bag, the spring loses the pressure from the bag, allowing the spring to drive the push plate to squeeze the storage bag, causing more glue to flow along the liquid guide groove and the gap between the first and second fixing frames, tightly fixing the two ventilation pipes together, greatly reducing the probability of breakage during normal use.

[0004] However, after prolonged use, air conditioning ducts accumulate a large amount of dust inside. In addition, most air conditioning ducts are installed at high locations, which makes daily cleaning and maintenance difficult. Cleaning personnel cannot directly reach the inside of the air conditioner for cleaning. As the air conditioner operates, the dust accumulated inside carries various bacteria, viruses, mold and other microorganisms. These pollutants will enter the room with the air blown out by the air conditioner, polluting the indoor air environment. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that in the existing technology, a large amount of dust accumulates inside the air conditioning ducts after long-term use. At the same time, most air conditioning ducts are installed at high positions, which makes daily cleaning and maintenance difficult. Cleaning personnel cannot directly reach the inside of the air conditioner for cleaning. As the air conditioner is running, the dust accumulated inside will carry various bacteria, viruses, mold and other microorganisms. These pollutants will enter the room with the air blown out by the air conditioner and pollute the indoor air environment. Therefore, a HVAC duct structure that is easy to clean is proposed.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a HVAC duct structure that is easy to clean, comprising a first duct and a cleaning device. A second duct is provided on one side of the first duct, and a wall panel is provided on the upper surface of the first duct. The cleaning device is disposed on the surface of the first duct, and includes a mounting bracket. The mounting bracket is fixedly connected to the first duct, and a servo motor is fixedly connected to the surface of the mounting bracket. A roller is fixedly connected to the drive end of the servo motor. A pull rod is fixedly connected to the lower surface of the wall panel, and a pull rope is wound around the surface of the roller. The end of the pull rope away from the roller is fixedly connected to the pull rod. By setting up the cleaning device, and by using simple operating commands such as starting the cylinder and the servo motor, the entire process of lowering the duct from a high place to a low place for easy cleaning, and then resetting it after cleaning, can be realized. The operation is relatively simple, without the need for complex manual handling or adjustment, reducing the labor intensity and operational difficulty of the operators, and improving work efficiency.

[0007] Preferably, an assembly frame is fixedly connected to the upper surface of the first pipe. The surface of the assembly frame has insertion holes. By setting the assembly frame, during the normal use of the pipe, the assembly frame cooperates with the cylinder-driven telescopic rod to firmly fix the pipe in a predetermined position at a high place. When the telescopic rod is inserted into the assembly frame, it can prevent the pipe from moving or shaking due to various external forces during operation, ensuring the stability and safety of the pipe system and guaranteeing the normal operation of the pipe.

[0008] Preferably, a resistance block is fixedly connected to the side of the second pipe near the assembly frame, and a cylinder is fixedly connected to the upper surface of the resistance block. By setting the cylinder, when the pipe needs to be cleaned, the cylinder is activated, and the cylinder drives the telescopic rod to move backward and disengage from the assembly frame, thereby releasing the fixed constraint on the pipe. This allows the pipe to move downward when the servo motor drives the reel to release the wire and the pull rope is unrestrained, so that the operator can carry out maintenance and cleaning.

[0009] Preferably, the drive end of the cylinder is fixedly connected to a telescopic rod, which is inserted into a hole on the surface of the assembly frame. By setting the telescopic rod, under normal use of the pipeline, the telescopic rod is inserted into the assembly frame to fix the pipeline, keeping the pipeline in a predetermined position at a high level, and ensuring the normal operation and stability of the pipeline system.

[0010] Preferably, a stop block is fixedly connected to the side of the first pipe near the resistance block. The stop block abuts against the resistance block. By setting the stop block, after cleaning is completed, the servo motor drives the reel to rotate and rewind the rope, so that the pipe moves upward and resets. The stop block and the resistance block cooperate with each other. When the stop block abuts against the resistance block, it means that the pipe has risen to the predetermined correct position.

[0011] Preferably, there are four cylinders, which are arranged symmetrically in a vertical position.

[0012] Preferably, the first pipe and the second pipe have the same diameter and are compatible with each other. A column is fixedly connected to the upper surface of the first pipe, and the column is slidably connected to the wall panel. By setting the column, it is easier to assist the first pipe and the second pipe in aligning during resetting, thereby increasing the accuracy and stability of resetting.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this utility model, when the pipeline needs to be cleaned, the cylinder is activated, which drives the telescopic rod to move backward and disengage from the assembly frame. At this time, the servo motor is activated, which drives the reel to rotate, releasing the cable and freeing the pull rope. The pipeline then moves downward, while the column slides, supporting the pipeline. Once the pipeline reaches its lowest point, the operator can perform maintenance and cleaning. After cleaning, the servo motor drives the reel to rotate and rewind the pull rope, causing the pipeline to move upward and reset. When the stop block and resistance block collide, the pipeline becomes difficult to move. At this point, the cylinder drives the telescopic rod to insert into the assembly frame for fixation. This utility model is thus designed.

[0015] By using simple operating commands such as starting cylinders and servo motors, the entire process of lowering the pipeline from a high place to a low place for easy cleaning, and then resetting it after cleaning, can be realized. The operation is relatively simple, without the need for complicated manual handling or adjustment, which reduces the labor intensity and difficulty of operation for operators and improves work efficiency.

[0022] Please see Figures 1-5 This utility model provides a technical solution: an easy-to-clean HVAC duct structure, including a first duct 1 and a cleaning device 4, a second duct 2 is provided on one side of the first duct 1, a wall panel 3 is provided on the upper surface of the first duct 1, and the cleaning device 4 is provided on the surface of the first duct 1.

[0023] In this embodiment: the cleaning device 4 includes a mounting base 42, which is fixedly connected to the first pipe 1. A servo motor 43 is fixedly connected to the surface of the mounting base 42, and a roller 41 is fixedly connected to the drive end of the servo motor 43. A pull rod 45 is fixedly connected to the lower surface of the wall panel 3. A pull rope 44 is wound around the surface of the roller 41, and the end of the pull rope 44 away from the roller 41 is fixedly connected to the pull rod 45. By setting up the cleaning device 4, the entire process of the pipe descending from a high place to a low place for easy cleaning and then resetting after cleaning can be realized through simple operating commands such as starting the cylinder 47 and the servo motor 43. The operation is relatively simple, without the need for complicated manual handling or adjustment, which reduces the labor intensity and operation difficulty of the operators and improves work efficiency.

[0024] Specifically, an assembly frame 46 is fixedly connected to the upper surface of the first pipe 1. The surface of the assembly frame 46 has insertion holes. By setting the assembly frame 46, during the normal use of the pipe, the assembly frame 46 cooperates with the telescopic rod 48 driven by the cylinder 47 to firmly fix the pipe in a predetermined position at a high place. When the telescopic rod 48 is inserted into the assembly frame 46, it can prevent the pipe from moving or shaking due to various external forces during operation, ensuring the stability and safety of the pipe system and guaranteeing the normal operation of the pipe.

[0025] Specifically, a resistance block 410 is fixedly connected to the side of the second pipe 2 near the assembly frame 46. A cylinder 47 is fixedly connected to the upper surface of the resistance block 410. By setting the cylinder 47, when the pipe needs to be cleaned, the cylinder 47 is activated, and the cylinder 47 drives the telescopic rod 48 to move backward and disengage from the assembly frame 46, thereby releasing the fixed constraint on the pipe. This allows the pipe to move downward when the subsequent servo motor 43 drives the reel 41 to release the line and the pull rope 44 is unrestrained, so that the operator can carry out maintenance and cleaning.

[0026] Specifically, a telescopic rod 48 is fixedly connected to the drive end of the cylinder 47. The telescopic rod 48 is inserted into the insertion hole on the surface of the assembly frame 46. By setting the telescopic rod 48, under normal use of the pipeline, the telescopic rod 48 is inserted into the assembly frame 46 to fix the pipeline and keep the pipeline in a predetermined position at a high level, thus ensuring the normal operation and stability of the pipeline system.

[0027] Specifically, a stop block 49 is fixedly connected to the side of the first pipe 1 near the resistance block 410, and the stop block 49 abuts against the resistance block 410.

[0028] In this embodiment: by setting the abutment block 49, after cleaning is completed, the servo motor 43 drives the reel 41 to rotate and rewind the rope 44, so that the pipe moves upward and resets. The abutment block 49 and the resistance block 410 cooperate with each other. When the abutment block 49 and the resistance block 410 abut against each other, it means that the pipe has risen to the predetermined correct position.

[0029] Specifically, there are four cylinders 47, which are arranged symmetrically in an upper and lower position.

[0030] Specifically, the first pipe 1 and the second pipe 2 have the same diameter and are compatible with each other. A column 411 is fixedly connected to the upper surface of the first pipe 1, and the column 411 is slidably connected to the wall panel 3.

[0031] In this embodiment: by setting up the column 411, it is easier to align the first pipe 1 and the second pipe 2 during reset, thereby increasing the accuracy and stability of reset.

[0032] Working Principle: When pipe cleaning is required, cylinder 47 is activated, driving telescopic rod 48 to move backward and disengage from assembly frame 46. At this time, servo motor 43 is activated, driving reel 41 to rotate. Reel 41 releases the cable, releasing the pull rope 44, causing the pipe to move downward. Simultaneously, column 411 slides, supporting the pipe. Once the pipe reaches the lowest point, the operator can perform maintenance and cleaning. After cleaning, servo motor 43 drives reel 41 to rotate and rewind pull rope 44, causing the pipe to move upward and reset. When stop block 49 abuts against resistance block 410, the pipe becomes difficult to move. At this point, cylinder 47 drives telescopic rod 48 to insert into assembly frame 46 for fixation. By setting up this utility model, the entire process of lowering the pipe from a high point to a low point for easy cleaning and resetting it after cleaning can be achieved through simple operating commands such as activating cylinder 47 and servo motor 43. The operation is relatively simple, requiring no complex manual handling or adjustment, reducing the labor intensity and difficulty of operation, and improving work efficiency.
