Description

Technical Field

[0001] This application relates to the technical field of refrigeration equipment, and in particular to a refrigerated smart vending machine. Background Technology

[0002] With the improvement of people's living standards and changes in consumption habits, smart vending machines, as a convenient retail terminal device, are increasingly favored by the market. They not only provide 24-hour uninterrupted service to meet consumers' shopping needs anytime, anywhere, but also effectively reduce operating costs and improve sales efficiency.

[0003] Refrigerated smart vending machines are devices that integrate refrigeration and automatic vending functions, widely used in commerce and retail. With technological advancements, these machines have played a significant role in improving product preservation and enhancing shopping convenience. However, in actual use, when the refrigeration system is running, the temperature inside the cabinet is significantly lower than the ambient temperature outside. When the cold air inside the cabinet comes into contact with the inner wall or door, water vapor in the air condenses into water droplets. When customers frequently open and close the cabinet door, warm, humid air from outside enters and mixes with the cold air, causing water vapor to condense again. Proper drainage of condensate not only affects the normal operation of the equipment but also directly impacts the refrigeration effect and product quality.

[0004] In existing technologies, to solve the condensation problem, the condensation is usually discharged directly outside the cabinet through a simple drain pipe. The condensation treatment efficiency is low, which can easily lead to the condensation remaining for too long, potentially causing problems such as dampness or mold growth inside the equipment, thereby affecting the refrigeration effect and the service life of the equipment. Summary of the Invention

[0005] To address the issue of low condensate treatment efficiency, this application provides a refrigerated smart vending machine.

[0006] The refrigerated smart vending machine provided in this application adopts the following technical solution: A refrigerated smart vending machine includes a cabinet body and a cabinet door. A drain pipe is fixedly installed through the inner bottom surface of the cabinet body. A drain groove connected to the drain pipe is opened on the inner bottom surface of the cabinet body. A water collection tray is installed at the bottom of the cabinet body. The drain pipe is located above the water collection tray. A ventilation slot is opened on one side of the water collection tray, and a fan is installed in the ventilation slot. Several ventilation holes are opened on the other side of the water collection tray. An installation frame is vertically slidable inside the water collection tray. A porous cloth is installed inside the installation frame. The porous cloth can be immersed in the condensate in the water collection tray.

[0007] By adopting the above technical solution, the condensate on the inner wall of the cabinet is collected in the drain groove and then enters the water collection pan through the drain pipe. The condensate spreads in the water collection pan, and the porous cloth moves downward and absorbs the condensate. After absorbing the condensate, the porous cloth moves upward, thereby increasing the contact area of ​​the condensate. The fan blows air on the condensate on the porous cloth and in the water collection pan to accelerate the evaporation rate of the condensate.

[0008] Preferably, a movable frame is vertically slidably installed inside the water collection tray. Vertically arranged guide rods are fixed at the corners of the movable frame. The movable frame slides vertically with the cabinet through the guide rods. A fixing rod is fixed between the bottom surface of the movable frame and the top surface of the mounting frame. A rotating rod is rotatably installed inside the water collection tray. Two cams are fixedly fitted on the outer circumference of the rotating rod. The outer circumference of the cams can abut against the bottom surface of the movable frame. A motor is installed on the water collection tray. The output end of the motor is coaxially fixedly connected to the end of the rotating rod. Movable blocks are fixed on both sides of the movable frame. A spring is fixed on the bottom surface of the movable block. The bottom end of the spring is fixedly connected to the inner bottom surface of the water collection tray.

[0009] By adopting the above technical solution, the motor is started, the motor drives the rotating rod to rotate, the rotating rod drives the cam to rotate, when the protruding part of the cam abuts against the moving frame, the moving frame drives the mounting frame to move upward, when the protruding part of the cam separates from the moving frame, the moving frame moves downward under the elastic force of the spring, so that the porous cloth in the mounting frame fits against the bottom surface of the water collection tray.

[0010] Preferably, the side of the cabinet is provided with a movable channel for placing the water collection tray. The inner top surface of the movable channel is provided with a plurality of slots. The cabinet is equipped with a locking block that slides vertically through the slots. The top surface of the water collection tray is provided with a locking groove for inserting the locking block. A baffle is provided on one side of the movable channel, and the water collection tray can abut against the baffle. A connecting channel is provided on the side of the baffle.

[0011] By adopting the above technical solution, the water collection tray is placed into the movable channel, the water collection tray abuts against the baffle, and then the locking block is inserted into the locking groove to lock and fix the water collection tray.

[0012] Preferably, a sliding spring is fixed to the top surface of the card block, the bottom end of the sliding spring is fixedly connected to the top surface of the card block, and an inclined surface is provided on the bottom surface of the card block, the inclined surface being located on the side of the card block away from the baffle.

[0013] By adopting the above technical solution, the water collection tray is inserted into the movable through groove. The water collection tray abuts against the inclined surface and pushes the locking block to move upward. The sliding spring is in a compressed state. When the water collection tray abuts against the baffle, the locking block moves downward under the elastic force of the compressed spring and inserts into the locking groove.

[0014] Preferably, a connecting rod is rotatably installed in the movable channel, a baffle is sleeved on the outer periphery of the connecting rod, a torsion spring is sleeved on the outer periphery of the connecting rod, one end of the torsion spring is fixedly connected to the inner wall of the movable channel, and the other end of the torsion spring is fixedly connected to the baffle. A limit groove is opened on the side of the cabinet, and a limit block is fixed on the side of the baffle. The limit block can be inserted into the limit groove.

[0015] By adopting the above technical solution, the baffle abuts against the water collection tray under the elastic force of the torsion spring, and the limiting block is inserted into the limiting groove, so that the baffle remains in a vertical state.

[0016] Preferably, a sealing ring is rotatably mounted on the inner top surface of the movable channel, the top surface of the sealing ring is in contact with the bottom surface of the drain pipe, and a plurality of drain holes are opened on the top surface of the sealing ring. Each drain hole corresponds to a drain pipe and can be connected to the drain pipe. A rotating assembly for driving the sealing ring to rotate is provided on the cabinet.

[0017] By adopting the above technical solution, the sealing ring fits snugly against the bottom surface of the drain pipe, preventing outside air from entering the cabinet through the drain pipe, reducing the generation of condensate, and ensuring the refrigeration effect of the cabinet. When there is a lot of condensate in the drain pipe, the rotating component drives the sealing ring to rotate, so that the drain hole is connected to the drain pipe, allowing the condensate in the drain pipe to be discharged into the water collection tray through the drain hole.

[0018] Preferably, the inner top surface of the movable channel is provided with a clearance groove, the rotating assembly includes a drive rod rotatably installed in the clearance groove, the outer circumferential surface of the drive rod is provided with a plurality of synchronization grooves, the inner circumferential surface of the sealing ring is fixed with a synchronization rod, the synchronization rod is inserted into the synchronization groove, and the cabinet is provided with a drive assembly for driving the drive rod to rotate.

[0019] By adopting the above technical solution, the drive assembly drives the drive rod to rotate, and the drive rod drives the sealing ring to rotate synchronously through the synchronous groove and the synchronous rod.

[0020] Preferably, the driving assembly includes a fixed sleeve fixed in the clearance groove, a driving rod inserted in the fixed sleeve, the driving rod slidingly engaging with the fixed sleeve in a vertical direction, an arc-shaped groove on the outer circumferential surface of the driving rod, a driving ball fixed on the inner circumferential surface of the fixed sleeve, the driving ball slidingly engaging with the driving rod through the arc-shaped groove, and a synchronizing rod slidingly engaging with the driving rod in a vertical direction through the synchronizing groove.

[0021] By adopting the above technical solution, the drive rod slides vertically within the fixed sleeve, causing the drive ball to move within the arc-shaped groove, thereby driving the drive rod to rotate, which in turn drives the synchronizing rod to rotate.

[0022] Preferably, an electromagnet is fixed to the inner top surface of the fixed sleeve. When the electromagnet is energized, it can attract the drive rod. A reset ring is sleeved on the outer circumference of the drive rod. The reset ring is rotatably connected to the drive rod. A reset spring is sleeved on the outer circumference of the fixed sleeve. The top end of the reset spring is fixedly connected to the inner top surface of the relief groove, and the bottom end of the reset spring is fixedly connected to the top surface of the reset ring.

[0023] By adopting the above technical solution, when the electromagnet is energized, it attracts the drive rod, which moves upward. When the electromagnet is de-energized, the drive rod moves downward under the elastic force of the return spring, and the drive rod returns to its original position.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The condensate on the inner wall of the cabinet collects in the drain groove and then enters the water collection pan through the drain pipe. The condensate spreads in the water collection pan, and the porous cloth moves downward to absorb the condensate. After absorbing the condensate, the porous cloth moves upward, thereby increasing the contact area of ​​the condensate. The fan blows air on the condensate on the porous cloth and in the water collection pan to accelerate the evaporation rate of the condensate. 2. Start the motor. The motor drives the rotating rod to rotate, and the rotating rod drives the cam to rotate. When the protruding part of the cam abuts against the moving frame, the moving frame drives the mounting frame to move upward. When the protruding part of the cam separates from the moving frame, the moving frame moves downward under the elastic force of the spring, so that the perforated cloth in the mounting frame fits against the bottom surface of the water collection tray. 3. The sealing ring fits snugly against the bottom of the drain pipe, preventing outside air from entering the cabinet through the drain pipe, thus reducing condensation and ensuring the cabinet's refrigeration effect. When there is a lot of condensation in the drain pipe, the rotating component drives the sealing ring to rotate, connecting the drain hole to the drain pipe so that the condensation in the drain pipe can be drained into the collection tray through the drain hole.

[0032] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0033] This application discloses a refrigerated smart vending machine. (Refer to...) Figure 1 and Figure 2 The refrigerated smart vending machine includes a hinged cabinet body 1 and a cabinet door 11. A drain pipe 13 is fixedly installed through the inner bottom surface of the cabinet body 1, and a drain groove 12 connected to the drain pipe 13 is opened on the inner bottom surface of the cabinet body 1. A water collection tray 2 is installed at the bottom of the cabinet body 1, and the drain pipe 13 is located above the water collection tray 2.

[0034] Reference Figure 2 and Figure 3A ventilation slot 21 is provided on one side of the water collection tray 2, and a fan 22 is installed inside the ventilation slot 21. Several ventilation holes 23 are provided on the other side of the water collection tray 2. A mounting frame 3 is vertically slidably installed inside the water collection tray 2, and a porous cloth 31 is installed inside the mounting frame 3. The porous cloth 31 can be immersed in the condensate in the water collection tray 2, and absorbs the condensate and increases the contact area by moving up and down. The porous cloth 31 can be made of polyester fiber or nylon material, which has good water absorption and air permeability, and the surface is treated with hydrophilicity to quickly absorb condensate.

[0035] Reference Figure 3 A movable frame 32 is vertically slidable inside the water collection tray 2. A fixing rod 33 is fixed between the bottom surface of the movable frame 32 and the top surface of the mounting frame 3. Vertically arranged guide rods 34 are fixed through and fixed at the corners of the movable frame 32. The movable frame 32 slides vertically with the cabinet 1 through the guide rods 34. The cross-sectional shape of the guide rods 34 is circular or square, and it fits with the sliding holes of the mounting frame 3 with clearance to ensure smooth sliding.

[0036] Reference Figure 3 A rotating rod 24 is rotatably mounted inside the water collection tray 2. Two cams 25 are fixedly fitted onto the outer circumference of the rotating rod 24, and the outer circumference of the cams 25 can abut against the bottom surface of the movable frame 32. A motor 26 is mounted on the water collection tray 2, and the output end of the motor 26 is coaxially and fixedly connected to the end of the rotating rod 24. Movable blocks 35 are fixed on both sides of the movable frame 32, and a spring 36 is fixed to the bottom surface of the movable block 35. The bottom end of the spring 36 is fixedly connected to the inner bottom surface of the water collection tray 2.

[0037] When the cam 25 rotates, its protruding part abuts against the contact surface, pushing the moving frame 32 to move upward; when the protruding part of the cam 25 separates from the contact surface, the moving frame 32 returns to its original position under the action of the spring 36, forming a periodic reciprocating motion. This reciprocating motion allows the porous cloth 31 to be repeatedly immersed in and detached from condensate, significantly improving the adsorption and evaporation efficiency of condensate.

[0038] When the mounting frame 3 moves downward, the porous cloth 31 is completely immersed in the condensate, fully absorbing the moisture; when the mounting frame 3 moves upward, the porous cloth 31 leaves the water surface, increasing the evaporation area of ​​the condensate. This periodic adsorption and evaporation process significantly improves the condensate treatment efficiency.

[0039] Reference Figure 2 and Figure 4The cabinet body 1 has a movable channel 14 on its side for placing the water collection tray 2. The inner top surface of the movable channel 14 has several slots 41. The cabinet body 1 is vertically slidably mounted with a locking block 4 through the slots 41. The top surface of the water collection tray 2 has a locking groove 27 for inserting the locking block 4. A sliding spring 42 is fixed to the top surface of the locking block 4. The bottom end of the sliding spring 42 is fixedly connected to the top surface of the locking block 4. The bottom surface of the locking block 4 has an inclined surface 43, which is located on the side of the locking block 4 away from the baffle 5.

[0040] Reference Figure 2 and Figure 4 A baffle 5 is provided on one side of the movable channel 14, and the water collection tray 2 can abut against the baffle 5. A connecting channel 51 is provided on the side of the baffle 5. A connecting rod 52 is rotatably installed in the movable channel 14, and the baffle 5 is sleeved on the outer periphery of the connecting rod 52. A torsion spring 53 is sleeved on the outer periphery of the connecting rod 52. One end of the torsion spring 53 is fixedly connected to the inner wall of the movable channel 14, and the other end of the torsion spring 53 is fixedly connected to the baffle 5. A limiting groove 55 is provided on the side of the cabinet 1, and a limiting block 54 is fixed on the side of the baffle 5. The limiting block 54 can be inserted into the limiting groove 55.

[0041] Insert the water collection tray 2 into the movable through groove 14. The water collection tray 2 abuts against the inclined surface 43 and pushes the locking block 4 to move upward. The sliding spring 42 is in a compressed state. When the water collection tray 2 abuts against the baffle 5, the locking block 4 moves downward under the elastic force of the compressed spring and inserts into the locking groove 27 to lock and fix the water collection tray 2. The baffle 5 abuts against the water collection tray 2 under the elastic force of the torsion spring 53, and the limiting block 54 is inserted into the limiting groove 55, so that the baffle 5 remains in a vertical state to prevent the water collection tray 2 from accidentally falling out.

[0042] Reference Figure 5 and Figure 6 A sealing ring 6 is rotatably mounted on the inner top surface of the movable channel 14, and the top surface of the sealing ring 6 is in contact with the bottom surface of the drain pipe 13. Several drain holes 61 are formed on the top surface of the sealing ring 6, each corresponding to a drain pipe 13, and the drain holes 61 are connected to the drain pipe 13. A clearance groove 62 is formed on the inner top surface of the movable channel 14, and a vertically arranged drive rod 64 is rotatably mounted within the clearance groove 62. Several synchronization grooves 641 are formed on the outer circumferential surface of the drive rod 64, and a synchronization rod 63 is fixed to the inner circumferential surface of the sealing ring 6. The synchronization rod 63 is inserted into the synchronization groove 641, and the synchronization rod 63 slides vertically with the drive rod 64 through the synchronization groove 641.

[0043] Reference Figure 5 and Figure 6A fixed sleeve 7 is fixed inside the clearance groove 62, and a drive rod 64 is inserted into the fixed sleeve 7, sliding vertically with the fixed sleeve 7. An arc-shaped groove 642 is formed on the outer circumferential surface of the drive rod 64, and a drive ball 71 is fixed on the inner circumferential surface of the fixed sleeve 7, slidingly engaging with the drive rod 64 through the arc-shaped groove 642. An electromagnet 72 is fixed on the inner top surface of the fixed sleeve 7, attracting the drive rod 64 when energized. A reset ring 65 is fitted on the outer circumferential surface of the drive rod 64, rotatably connected to the drive rod 64. A reset spring 66 is fitted on the outer circumferential surface of the fixed sleeve 7, with its top end fixedly connected to the inner top surface of the clearance groove 62 and its bottom end fixedly connected to the top surface of the reset ring 65.

[0044] Under normal circumstances, the top surface of the sealing ring 6 is tightly fitted with the bottom surface of the drain pipe 13, forming a sealed structure to prevent outside air from entering the cabinet 1. When there is a large amount of condensate in the drain pipe 13, the electromagnet 72 is energized to attract the drive rod 64, which moves upward. The drive ball 71 moves within the arc-shaped groove 642, causing the drive rod 64 to rotate, which in turn drives the synchronizing rod 63 to rotate, causing the sealing ring 6 to rotate. The drain hole 61 then connects with the drain pipe 13, and the condensate drains into the collection tray 2 through the drain hole 61. When the electromagnet 72 is de-energized, the drive rod 64 moves downward under the elastic force of the return spring 66, resetting the drive rod 64. The sealing ring 6 returns to its original position, reforming the sealed structure. This not only improves the reliability of the condensate treatment system but also ensures the refrigeration effect of the cabinet 1.

[0045] The implementation principle of a refrigerated intelligent vending machine according to this application embodiment is as follows: by increasing the contact area of ​​condensate and using a fan 22 to accelerate evaporation, the problem of low condensate treatment efficiency in the prior art is effectively solved. The up-and-down movement of the porous cloth 31 allows the condensate to be fully exposed to the air, and the blowing action of the fan 22 further accelerates the evaporation process, thereby reducing the condensate retention time and avoiding the problems of dampness and mold growth inside the equipment. This design not only improves the refrigeration effect but also extends the service life of the equipment, representing a significant improvement over the prior art.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
