It is used for heating and drying.

[0025] A hollow cylinder 4 is vertically positioned within the washing chamber 1. This cylindrical cylinder is hollow and open at the bottom. It extends downward through a first mounting plate 5 and is rotatably connected thereto. A second power assembly is assembled within the drying chamber 2 and is in transmission connection with the hollow cylinder 4, driving its rotation.

[0026] The second power assembly includes a motor 11, bolted to the drying box 2. The output shaft of motor 11 is vertically upward and coaxially connected to the second pulley 9. The bottom of the hollow cylinder 4 is coaxially connected to the first pulley 8. A belt 10 passes through a through hole 12. The first and second pulleys 8 and 9 are driven by belt 10, which is in a limited sliding engagement with the box body where through hole 12 is located.

[0027] The top of the hollow cylinder 4 is fixedly connected to a top head 29, and the hollow cylinder 4 is inserted into the glass container 6. The top head 29 abuts against the inner wall of the bottom of the glass container 6 to support the glass container 6.

[0028] The hollow cylinder 4 has a plurality of radially cut through grooves 28 arranged in layers along the axial direction of the hollow cylinder 4. Each layer has four through grooves 28, and the four through grooves 28 in the same layer are evenly distributed along the circumference of the hollow cylinder 4. Each through groove 28 connects the inside and outside of the hollow cylinder 4.

[0029] Of the four through slots 28 on the same layer, two horizontally opposite through slots 28 each have a slide rod 14 extending radially across the hollow cylinder 4, and the other two horizontally opposite through slots 28 each have a support block 25 extending radially across the hollow cylinder 4. Each slide rod 14 slides vertically up and down, and each support block 25 rotates vertically up and down.

[0030] All through-slots 28, through which the slide rods 14 pass, are divided into two groups. The through-slots 28 in the same group are located on different levels and on the same vertical line. The ends of the slide rods 14 within the through-slots 28 in the same group, facing away from the central axis of the hollow cylinder 4, are fixedly connected to a single brush block 15. Each brush block 15 is arranged vertically and is a sponge. Each brush block 15 is positioned within the glassware 6 and slidably abuts against the inner side walls of the glassware 6, thereby cleaning the inner side walls of the glassware 6.

[0031] In this embodiment, the sliding rod 14 can be a spring telescopic rod selected according to actual use requirements, so as to adapt to glassware 6 with different cup diameters.

[0032] The hollow cylinder 4 has multiple limiting grooves 24 bored into it. These grooves 24 correspond one-to-one with all the through-grooves 28 through which the slide bars 14 pass. Each limiting groove 24 is connected to a corresponding through-groove 28. A slider is welded to each slide bar 14, and each slider slides in a limited position within a limiting groove 24 connected to the through-groove 28 of its corresponding slide bar 14, ensuring smooth sliding of the slide bars 14.

[0033] Each support block 25 is rotatably connected to the body of the hollow cylinder 4 via a rotating shaft, and an end of each support block 25 away from the central axis of the hollow cylinder 4 is fixedly connected to a nozzle 13 .

[0034] The two slide bars 14 and the two support blocks 25 on the same layer are coupled to each other via a connecting member. Each connecting member comprises a connecting ring 22, and each connecting ring 22 is coaxial with the hollow cylinder 4.

[0035] Two sliding rods 14 on the same level are fixedly connected to the same connecting ring 22. A first power assembly, comprising electric push rods 23, is fixedly mounted within the hollow cylinder 4. Screws secure the two push rods 23 within the hollow cylinder 4. The output shafts of both push rods 23 face vertically downward and extend and retract synchronously. The extension and retraction axes of the two push rods 23 are fixedly connected to all the connecting rings 22 via a connecting rod 21, propelling all the sliding rods 14 vertically up and down.

[0036] Each support block 25 has a horizontally defined waist-shaped groove cut into its end near the central axis of the hollow cylinder 4. A drive roller 26 runs transversely through each waist-shaped groove. The drive roller 26 within each waist-shaped groove of the support block 25 is rotatably connected to the connecting ring 22 connected to the slide bar 14 located on the same level as the support block 25. Each drive roller 26 both rolls along its waist-shaped groove and abuts against its corresponding support block 25 for transmission, driving the support block 25 in vertical rotation.

[0037] The cleaning tank 1 contains the flushing liquid. A filter plate 3 is placed horizontally below the first mounting plate 5 and is fixedly connected to the cleaning tank 1. A through hole 12 is located between the filter plate 3 and the first mounting plate 5. Multiple return holes are drilled vertically in the filter plate 3, which also serve as filter holes for filtering the returning flushing liquid.

[0038] A water pump 7 is fixed with bolts in the cleaning box 1. The water pump 7 is located below the filter plate 3, and the flushing liquid submerges the water pump 7. The water outlet of the water pump 7 is connected to all the nozzles 13 through a pipeline passage. It is used for spraying water.

[0039] The conduit passage includes a hollow tube 27, which is located within and coaxially fixedly connected to the hollow cylinder 4. The interior of the hollow tube 27 is hollow, and both ends are sealed. The water outlet of the water pump 7 is connected to the hollow tube 27 via a rigid tube. One end of the rigid tube is fixedly connected to the water outlet of the water pump 7, while the other end is rotatably connected to the hollow tube 27 via a rotary joint.

[0040] The hollow tube 27 is fixedly connected to a plurality of hoses, which are not shown in the figure. The plurality of hoses correspond to the plurality of nozzles 13 one by one, and the nozzle of each hose away from the hollow tube 27 is fixedly connected to the corresponding nozzle 13.

[0041] Working Principle: During use, the glass container 6 is placed upside down on the hollow cylinder 4. The hollow cylinder 4 then extends into the glass container 6, with the top 29 contacting the inner wall of the bottom of the glass container 6. At the same time, the mouth of the glass container 6 contacts the first mounting plate 5. During this process, the two brush blocks 15 slide into the glass container 6 and contact the inner wall of the side of the glass container 6.

[0042] Next, the glassware 6 is held stationary while the motor 11 is activated. The output shaft of the motor 11 rotates the second pulley 9, which in turn rotates the first pulley 8 via the belt 10. The first pulley 8 then rotates the hollow cylinder 4, which in turn pushes all the slide bars 14 in orbit around its central axis. The slide bars 14 then drive the attached brushes 15 in orbit around its central axis. During this process, the brushes 15 rotate horizontally, removing stains from the side walls of the glassware 6. Simultaneously, the head 29 rotates, removing stains from the bottom wall of the glassware 6.

[0043] When the motor 11 is started, the two electric push rods 23 are also started. The telescopic shafts of the two electric push rods 23 reciprocate and extend, driving all the connecting rings 22 to move up and down in the vertical direction. During this process, the connecting rings 22 drive the connected sliding rods 14 to slide up and down in the vertical direction. The sliding rods 14 drive the connected brush blocks 15 to move up and down in the vertical direction and wipe the stains on the side inner wall of the glass container 6 in the vertical direction.

[0044] By controlling the rotational speed of the output shaft of the motor 11 and the extension and retraction frequency of the telescopic shafts of the two electric push rods 23, the two brush blocks 15 can achieve full coverage of the side inner wall of the glass container 6. The control process includes but is not limited to the motor 11 selecting a stepper motor and the output shaft rotating intermittently, while the telescopic shafts of the electric push rods 23 are intermittently retracting. The arc of each rotation of the output shaft of the motor 11 is the width of the brush block 15 in the horizontal direction. The time the motor 11 pauses after rotating one arc is the time required for the telescopic shaft of the electric push rod 23 to complete one extension and retraction. When the output shaft of the motor 11 rotates, the telescopic shaft of the electric push rod 23 stops retracting and retracting. When the output shaft of the motor 11 stops rotating, the electric push rod 23 completes one extension and retraction.

[0045] When the motor 11 is started, the water pump 7 is started. The water pump 7 extracts the flushing liquid in the cleaning box 1 and sprays it toward the side inner wall of the glassware 6 through the spray nozzle 13, thereby the side inner wall of the glassware 6 is rinsed.

[0046] As the connecting ring 22 moves up and down, the drive roller 26 pushes the support block 25 to rotate vertically. Simultaneously, the hollow cylinder 4 pushes the support block 25 to rotate about its central axis. During this process, the support block 25 both drives the connected spray head 13 to swing back and forth and rotate about its central axis. This allows for multi-angle, wide-area rinsing of the inner side of the glassware 6. During the rinsing process, the rinse water flows back into the cleaning tank 1 through the reflux holes in the filter plate 3.

[0047] After the glassware 6 is cleaned, the water pump 7, the motor 11 and all the electric push rods 23 are turned off.

[0048] Next, the cleaned glassware 6 is placed with its mouth facing downward on a placement plate 20. The blower and heater 18 are then activated. The blower drives the fan 17, which heats the air through the heater head 19. The fan 17 blows the heated air toward the placement plate 20. The heated air then flows through the air guide holes in the placement plate 20 and toward the glassware 6, thereby drying the glassware 6.

[0049] After drying is finished, the blower and heater 18 are turned off.

[0050] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
