Description

Technical Field

[0001] This utility model relates to the field of baby bottle cleaning technology, specifically a baby bottle cleaning, sterilization and drying integrated machine. Background Technology

[0002] With increasing awareness of infant health and the refinement of maternal and infant care needs, the thoroughness and safety of cleaning and sterilization of baby bottles, as frequently used infant tableware, have become a major concern. Traditional bottle cleaning methods rely heavily on manual hand washing or single-function equipment, resulting in incomplete cleaning, residue in hard-to-reach areas, insufficient sterilization, and susceptibility to secondary contamination. Furthermore, these methods are cumbersome and fail to meet the efficient, convenient, and safe needs of modern families. While some cleaning machines on the market offer cleaning or drying functions, they generally suffer from limitations such as limited functionality, low integration, the need for external water supply and drainage pipes, and the inability to achieve full automation. They are particularly ineffective at cleaning complex structures like the inside of bottles, threaded openings, and nipples, and lack proper sealing after drying, making them susceptible to contamination by environmental microorganisms. In addition, existing storage racks are mostly flat structures with poor drainage, leading to water accumulation and affecting drying efficiency and hygiene. Therefore, there is an urgent need for an intelligent solution that integrates cleaning, sterilization, drying, and storage functions, requires no external water source, is easy to operate, and provides thorough cleaning.

It includes a central sleeve 410, 4 to 8 radial manifolds 420, and 2 concentric annular connectors 430. The radial manifold 420 extends outward from the central sleeve 410. When there are 4 radial manifolds 420, the included angle between adjacent radial manifolds 420 is 90°. When there are 6 radial manifolds 420, the included angle between adjacent radial manifolds 420 is 60°. When there are 8 radial manifolds 420, the included angle between adjacent radial manifolds 420 is 45°. The free end of the radial manifold 420 extends upward to form a vertical spray pipe 440. The top of the vertical spray pipe 440 is provided with a spray hole 441 with a diameter of 0.5mm, which is used to spray water upward to achieve a powerful rinsing of the inner wall of the bottle. The lower shelf 400 can be used to place the bottle upside down, with the bottle placed on the vertical spray pipe 440.

[0046] See also Figure 3 The upper shelf 500 is located above the upper spray arm 330 and is detachably connected to the hanging points on the inner wall of the washing and drying chamber 230 via four elastic latches on its edge. The bearing surface of the upper shelf 500 has a raised structure with the center higher than the surrounding area. Specifically, it can be designed as a dome-shaped raised structure or a conical raised structure to guide the water flow to the surrounding area and avoid water accumulation. Multiple positioning protrusions can also be set on the bearing surface to effectively prevent small nipples and bottle caps from piling up or tipping over under the impact of water flow, ensuring that every part is washed by the water flow.

[0047] The lower shelf 400 and upper shelf 500 installed in the washing and drying chamber 230 support the bottles, nipples and bottle caps in a preset placement state, thereby improving the cleaning efficiency and quality of the bottles, nipples and bottle caps.

[0051] Cleaning Stage: The user places the baby bottle upside down on the vertical spray pipe 440 of the lower shelf 400, places the nipple, bottle cap, and other accessories on the upper shelf 500, and closes the top cover 220. The user selects the cleaning mode via the control panel 141, and the control device 140 starts the water pump 120, pumping clean water into the central water pipe 310. The water flows through various branch outlets into the lower spray arm 320, the upper spray arm 330, and the radial manifold 420 of the lower shelf 400, and is sprayed out from the first spray hole 321, the second spray hole 331, and the spray hole 441 to rinse the inner and outer surfaces of the baby bottle, nipple, bottle cap, and their accessories. The cleaning time is approximately 10 minutes.

[0052] Drainage stage: After cleaning is completed, the control device 140 controls the three-way valve to switch to drainage mode and starts the water pump 120 to pump the wastewater into the wastewater tank 710. The drainage time is about 2 minutes.

[0053] Disinfection and drying stage: The control device 140 starts the air supply device 130 and the PTC ceramic heater to generate 70°C hot air which is blown into the washing and drying chamber 230 for high-temperature disinfection and drying, which takes about 15 minutes; during the process, steam is discharged from the steam outlet 222 and condensate is collected and discharged along the condensate guide channel 221.

[0054] In summary, this embodiment provides a baby bottle washing, sterilizing, and drying all-in-one machine, which has significant advantages over existing technologies, including high integration, thorough cleaning, ease of use, and improved hygiene and safety. By integrating washing, high-temperature sterilization, and hot air drying functions into the same sealed chamber, and with the control device automatically controlling the coordinated operation of the water pump, air supply device, and heating device, fully automated continuous operation is achieved.
