Description

Technical Field

[0001] The present application relates to the technical field of compressor installation, and in particular to a compressor of a vending machine and a method for disassembling and assembling the compressor. Background Art

[0002] The compressor of a vending machine is mainly composed of a motor, a transmission mechanism, a compressor body, an exhaust valve, an intake valve, and an oil circuit system. The motor provides power, the transmission mechanism converts the motor speed into the operating speed of the compressor, the compressor body is the core part of the compressor, the exhaust valve and the intake valve control the inlet and outlet of the refrigerant, and the oil circuit system is responsible for providing sufficient lubrication and cooling for the compressor.

[0003] In the prior art, the compressor is usually installed on the back of the vending machine. The vending machine is usually placed against a wall. When installing or removing the vending machine, the vending machine needs to be moved first, the back of the vending machine is completely exposed, and then the back cover is removed before repair or replacement can be started, which is quite cumbersome. Summary of the invention

[0004] In view of the deficiencies in the prior art, the purpose of the present application is to provide a compressor for a vending machine and a method for disassembling and assembling the compressor, which is used to solve the problem that the vending machine compressor needs to be moved during maintenance, resulting in a cumbersome maintenance process.

[0005] The above-mentioned purpose of the present application is achieved through the following technical solutions: a compressor of a vending machine, comprising a compressor box body arranged at the bottom of an inner shell of the vending machine, a refrigeration component is fixedly installed inside the compressor box body, a delivery module installed on the outer shell of the vending machine is arranged at the front end of the compressor box body, tilting rods are arranged on both sides of the compressor box body, and force rods are fixedly arranged on one end of the tilting rods on both sides close to the front end of the outer shell of the vending machine, a rotating shaft is rotatably arranged at the connection between the tilting rod and the force rod, and the rotating shaft is rotatably connected to the compressor box body, a roller is rotatably arranged on the end of the tilting rod away from the force rod, and force columns fixedly connected to the compressor box body are arranged at both upper and lower ends of the force rod.

[0006] By adopting the above technical solution, when the compressor of the vending machine needs to be repaired, the delivery module is first taken out from the vending machine casing, and then the force-bearing rod is pulled upward. At this time, the force-bearing rod and the tilting rod will rotate with the rotating shaft. When the upper end of the force-bearing rod abuts against the force-bearing column, the roller at the end of the tilting rod will contact the bottom surface of the inner shell of the vending machine, and the compressor box body will be tilted as a whole. The force-bearing rod can be pulled and slid out more easily through the sliding of the roller. By combining the compressor structure into a compressor box body, during installation and maintenance, it is only necessary to take out the compressor box body alone to quickly carry out maintenance.

[0007] Furthermore, a pair of limiting rails are provided on both sides of the compressor housing on the inner bottom surface of the vending machine shell, the tilting rod is slidably connected to the limiting rails through rollers, and the limiting rails are fixedly connected to the vending machine shell.

[0008] By adopting the above-mentioned technical scheme, in order to ensure the accurate position of the refrigeration device inside the compressor box when it is installed in the vending machine after maintenance, the present application sets a limit slide rail on the inner bottom surface of the vending machine shell. When the compressor box is installed back to the bottom of the vending machine, the setting of the limit rails on both sides of the rollers on the tilting rod will ensure that the compressor box is installed in the vending machine in the accurate position.

[0009] Furthermore, a fixing hook is fixedly provided on the outer side of the limiting track away from the tilt rod, a fixing block is fixedly provided on the compressor casing near the fixing hook, a padlock is rotatably provided on the fixing block, and a hanging ring is rotatably provided on the padlock.

[0010] By adopting the above technical solution, in order to install the compressor box into the vending machine shell and fix it, after sliding the compressor box into the vending machine, hook the hanging ring on the fixing hook, and then turn the padlock, the compressor box will be unable to move and thus be fixed.

[0011] Furthermore, heat dissipation ports are provided at the bottom and back of the compressor housing, heat dissipation holes are provided on the vending machine housing at positions corresponding to the heat dissipation ports, a trapezoidal frame is fixedly provided at the upper end of the compressor, the cross-section of the trapezoidal frame is a right-angled trapezoidal shape, and an air outlet is provided on the trapezoidal inclined surface.

[0012] By adopting the above technical solution, when the compressor box is cooling, the cold air is directed upward to dissipate the heat inside the vending machine through the inclined air outlet. Since the compressor structure is composed of a compressor box in this application, the space inside the vending machine will become smaller, so the specifications of the heat dissipation holes are set to be larger than the current heat dissipation holes.

[0013] Furthermore, a plurality of driving fans are installed on the air outlet, and a guide plate is fixedly arranged on the ladder frame, and a plurality of guide holes are provided on the guide plate.

[0014] By adopting the above technical solution, multiple sets of fans are driven to improve the transmission efficiency of cold air at the air outlet, and the setting of the guide plate will evenly spread the cold air to the vending machine.

[0015] Furthermore, the delivery module includes a delivery box and an extension plate fixedly connected to both ends of the delivery box, a positioning rod is fixedly provided on the vending machine housing, the positioning rod has a positioning groove, and the extension plate is slidably connected to the positioning rod through the positioning groove.

[0016] By adopting the above technical solution, in order to make it more convenient to remove the shipping module, in the present application, by plugging in the extension plate and the positioning rod on the shipping box, the installation and removal of the shipping box can be completed by only pushing and pulling.

[0017] Furthermore, a force-bearing block is fixedly arranged on the baffle plate of the front side of the shipping box.

[0018] Furthermore, a rubber layer is fixedly provided on the outer side of the force-bearing block.

[0019] By adopting the above technical solution, the arrangement of the force-bearing blocks can provide force points when the shipping box is dismantled and installed.

[0020] Furthermore, an integrated electrical box fixedly connected to the compressor housing is provided on one side of the ladder frame, a through hole is provided in the integrated electrical wire, and the electrical wires of the refrigeration elements in the compressor are centrally connected to the integrated electrical box through the through hole.

[0021] By adopting the above technical solution, the wires of the refrigeration elements in the compressor housing are concentrated in an integrated electrical box. During repair and maintenance, the compressor housing can be quickly inspected and repaired only by checking the situation of the integrated electrical box.

[0022] Furthermore, a method for disassembling and assembling a compressor of a vending machine is applicable to a compressor of a vending machine described in any one of the above technical solutions, comprising the following steps: S1. Take out the delivery module from the vending machine housing to make room for the compressor housing to move; S2. Pull the stress rods on both sides upward, and the stress rods and the tilt rods will rotate around the rotation axis until the upper end of the stress rods abuts against the stress column, and the rollers at the end of the tilt rods contact the inner bottom surface of the vending machine shell, and the compressor box tilts as a whole. Continue to pull the stress rods, and slide the compressor box out of the vending machine through the sliding of the rollers on the limit rails; S3. After the compressor housing is completely removed, the refrigeration components can be repaired or replaced; S4. After the maintenance is completed, push the compressor box back to the bottom of the vending machine along the limit track through the rollers to ensure that the rollers are in close contact with the limit track and the compressor box is in the correct position; S5. When the compressor housing slides into place, hook the hanging ring onto the fixing hook and turn the padlock to fix the compressor housing in the vending machine.

[0023] By adopting the above technical solution, the delivery module is removed from the vending machine housing, which significantly increases the internal space and provides the necessary operating space for the movement and maintenance of the compressor box. The quick removal of the delivery module simplifies the subsequent steps, making the entire maintenance process smoother and more efficient. By pulling the force rod upward, the compressor box can be easily tilted using the lever principle, reducing the manpower requirements. The sliding of the roller on the limit track ensures the stability and smoothness of the compressor box during the removal process, avoiding scratches and damage. The tilting and sliding design enables the compressor box to be completely removed from the vending machine, providing sufficient operating space for maintenance personnel. After the compressor box is completely removed, maintenance personnel can easily approach the refrigeration components and perform necessary maintenance or replacement work, thereby improving maintenance efficiency. The spacious operating space reduces the safety risks during the maintenance process and ensures the safety of maintenance personnel. The compressor box is pushed back by the roller along the limit track to ensure that the box can accurately return to the predetermined position at the bottom of the vending machine. The combination of the hanging ring, the fixing hook and the padlock provides a reliable fixing method for the compressor box, preventing the box from moving or shaking during the operation of the vending machine.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. The compressor and related components are integrated into a separate compressor housing to achieve a modular design. This design allows the compressor housing to be removed alone without disassembling the entire vending machine when repairing or replacing the compressor, greatly simplifying the repair process and improving repair efficiency and convenience.

[0025] 2. The compact compressor box design effectively utilizes the internal space of the vending machine, allowing the vending machine to store more goods and improve storage efficiency. At the same time, the convenient disassembly and assembly method reduces the downtime of the vending machine, improves the overall operating efficiency of the vending machine, and thus improves the user experience.

[0026] 3. During the maintenance process, the spacious operating space reduces the safety risks of maintenance personnel. At the same time, the combination of padlocks and fixed hooks provides a reliable fixing method for the compressor box, preventing the box from moving or shaking during the operation of the vending machine, thereby enhancing the safety and reliability of the equipment. In addition, the design of the integrated electrical box makes the wire management more standardized, reduces the failure rate, and further improves the overall reliability of the equipment.

[0027] 4. When the compressor housing is removed, the force-bearing rod and the tilting rod are arranged to form a labor-saving lever, thereby improving the efficiency of removing the compressor housing. BRIEF DESCRIPTION OF THE DRAWINGS

When the compressor of the vending machine needs to be repaired, first take out the delivery module from the vending machine housing 1, and then pull the force rod 102 upwards. At this time, the force rod 102 and the tilting rod 101 will rotate with the rotating shaft 100. When the upper end of the force rod 102 abuts against the force column 104, the roller 103 at the end of the tilting rod 101 will contact the bottom surface of the vending machine housing 1, and the compressor box 2 will be tilted as a whole. Pull the force rod 102, and it can slide out more easily through the sliding of the roller 103. By combining the compressor structure into a compressor box 2, during installation and maintenance, you only need to take out the compressor box 2 separately, so you can quickly carry out maintenance.

[0032] In this embodiment, a pair of limiting rails 201 are provided on the inner bottom surface of the vending machine housing 1, and the tilting rod 101 is slidably connected to the limiting rails 201 through rollers 103, and the limiting rails 201 are fixedly connected to the vending machine housing 1. In order to ensure that the refrigeration device inside the compressor housing 2 is accurately positioned when it is installed in the vending machine after maintenance, the present application provides limiting rails on the inner bottom surface of the vending machine housing 1. When the compressor housing 2 is installed back to the bottom of the vending machine, the setting of the limiting rails 201 on both sides by the rollers 103 on the tilting rod 101 will ensure that the compressor housing 2 is accurately positioned when installed in the vending machine.

A positioning rod 402 is fixedly provided on the vending machine housing 1. The positioning rod 402 is provided with a positioning slot, and the extension plate 401 is slidably connected to the positioning rod 402 through the positioning slot.

[0037] In this embodiment, a force block 5 is fixedly arranged on the baffle plate of the front of the shipping box 4. A rubber layer is fixedly arranged on the outer side of the force block 5. The setting of the force block 5 can provide a force point when the shipping box 4 is dismantled and installed.

[0038] In this embodiment, an integrated electrical box 6 fixedly connected to the compressor housing 2 is provided on one side of the ladder frame 3, and a through hole is opened in the integrated electrical wire. The electrical wires of the refrigeration elements in the compressor are centrally connected to the integrated electrical box 6 through the through hole. By concentrating the electrical wires of the refrigeration elements in the compressor housing 2 in one integrated electrical box 6, during repair and maintenance, the compressor housing 2 can be quickly inspected and repaired only by checking the situation of the integrated electrical box 6.

[0039] A method for disassembling and assembling a compressor of a vending machine, which is applicable to a compressor of a vending machine in the above technical solution, comprises the following steps: S1, taking out a delivery module from a vending machine housing 1 to make room for the movement of a compressor housing 2; S2, pulling upwards the force-bearing rods 102 on both sides, the force-bearing rods 102 and the tilting rods 101 will rotate around the rotating shaft 100 until the upper end of the force-bearing rods 102 abuts against the force-bearing column 104, and the roller 103 at the end of the tilting rod 101 contacts the inner bottom surface of the vending machine housing 1, and the compressor housing 2 tilts as a whole, and the force-bearing rods 102 are continuously pulled, and the compressor housing 2 is rotated by The roller 103 slides on the limiting track 201 to slide the compressor box 2 out of the vending machine; S3, after the compressor box 2 is completely removed, the refrigeration components can be repaired or replaced; S4, after the repair is completed, the compressor box 2 is pushed back to the bottom of the vending machine along the limiting track 201 through the roller 103, ensuring that the roller 103 is in close contact with the limiting track 201 and the compressor box 2 is accurately positioned; S5, when the compressor box 2 slides into place, the hanging ring 205 is hooked on the fixing hook 202, and the padlock 204 is turned to fix the compressor box 2 in the vending machine. Removing the shipping module from the vending machine housing 1 significantly increases the internal space, providing the necessary operating space for the movement and maintenance of the compressor box 2. The rapid removal of the shipping module simplifies the subsequent steps, making the entire maintenance process smoother and more efficient. By pulling the force rod 102 upward, the tilting of the compressor box 2 can be easily achieved using the lever principle, reducing the manpower requirements. The sliding of the roller 103 on the limiting track 201 ensures the stability and smoothness of the compressor housing 2 during the removal process, avoiding scratches and damage. The tilting and sliding design enables the compressor housing 2 to be completely removed from the vending machine, providing sufficient operating space for maintenance personnel. After the compressor housing 2 is completely removed, maintenance personnel can easily approach the refrigeration components to perform necessary maintenance or replacement work, thereby improving maintenance efficiency. The spacious operating space reduces the safety risks during the maintenance process and ensures the safety of maintenance personnel. The roller 103 pushes the compressor housing 2 back along the limiting track 201, ensuring that the housing can accurately return to the predetermined position at the bottom of the vending machine. The combined use of the hanging ring 205, the fixing hook 202 and the padlock 204 provides a reliable fixing method for the compressor housing 2, preventing the housing from moving or shaking during the operation of the vending machine.

[0040] Specific implementation process: When maintenance is required, first cut off the power to ensure safety, and then quickly remove the shipping module to make room for the maintenance of the compressor box 2.

[0041] Next, the maintenance personnel pulls the stress rod 102 upwards, and uses the lever principle to rotate the tilting rod 101 and the stress rod 102 around the rotating shaft 100 until the upper end of the stress rod 102 abuts against the stress column 104, and the compressor housing 2 tilts as a whole. Continue to pull the stress rod 102, the roller 103 slides on the limit track 201, and the compressor housing 2 slides smoothly out of the vending machine to the maintenance area. In the spacious operating space, maintenance personnel can easily repair, inspect or replace refrigeration components, and access the integrated electrical box 6 to inspect or adjust the wire connection.

[0042] After the repair is completed, the compressor housing 2 is pushed back to the bottom of the vending machine along the limiting track 201 through the roller 103 to ensure the accurate position and adjust it to a horizontal state. Then, the hanging ring 205 is hooked on the fixing hook 202 and the padlock 204 is turned to firmly fix the compressor housing 2 in the vending machine. After that, the delivery module is reinstalled, the power supply of the vending machine is restored and the overall test is performed to ensure that all functions are operating normally.

[0043] During the whole process, the quick removal and installation of the delivery module simplified the maintenance steps, the tilting and sliding design made the movement of the compressor box 2 more convenient, and the cooperation of the roller 103 and the limit rail 201 ensured the stability and smoothness during the movement. In addition, the design of the integrated electrical box 6 made the wire management more standardized and improved the overall reliability of the equipment. Finally, the vending machine was quickly restored to use and continued to provide customers with a convenient shopping experience.

[0044] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
