Description

Technical Field

[0001] This invention relates to the technical field of baby bottle cleaning, and more specifically, to a baby bottle cleaning machine. Background Technology

[0002] With the increasing popularity of baby care equipment, fully automatic bottle cleaners, with their integrated cleaning, steam sterilization, and drying functions, are widely used in households, leading to continuous market demand growth. To meet these needs, the industry is constantly optimizing the heating, sterilization, and drying modules of these machines, striving to improve their operating efficiency and cleanliness.

[0003] Most fully automatic baby bottle cleaners on the market use a heating plate as the core heating element, which is fixedly installed at the bottom of the cleaning chamber. To prevent sewage and debris from directly adhering to the surface of the heating plate, a stainless steel filter screen is usually installed above the heating plate for shielding.

[0004] However, the relevant technology has at least one of the following problems: the heating plate at the bottom of the existing baby bottle washing machine has low power and slow heating. It is easy for dirt to accumulate when it comes into direct contact with sewage. Even with the addition of a filter, it cannot be cleaned thoroughly, which poses a hygiene risk. Summary of the Invention

[0005] The present invention solves at least one of the following problems: the heating plate at the bottom of the existing baby bottle washing machine has low power and slow heating. It is easy for dirt to accumulate when it comes into direct contact with sewage. Even with the addition of a filter, it cannot be cleaned thoroughly, which poses a hygiene hazard.

[0006] To address the above problems, this invention provides a baby bottle washing machine, which includes a shell, an inner tank, a water tank, and a cleaning device. The cleaning device includes: The spraying device is located in the cleaning chamber inside the inner tank. Washing pump, used to supply water to the spray device; A water pump is connected between the water tank and the washing pump via a pipeline. A heating module is installed between the water pump and the washing pump to provide hot water or steam to the washing pump. The washing pump, water pump, and heating module are installed in the mounting compartment between the base of the shell and the inner tank.

[0007] Compared with existing technologies, the technical effects achieved by this solution are as follows: This solution places the heating module between the water pump and the washing pump and houses it in the installation compartment between the base and the inner tank, away from the sewage area of ​​the inner tank cleaning compartment. Compared with the traditional bottom immersion heating structure, this avoids the heating module directly contacting sewage and scale buildup. Furthermore, the heating module is placed in the clean water path between the water pump and the washing pump, achieving independent closed-loop heating of the water path. This ensures that the heating module is always in the clean water path of the water tank and does not come into contact with the dirty water during the bottle washing process. This avoids scale and dirt residue adhering to the heating module and completely solves the problem of hygiene dead spots and potential hygiene hazards without the need for additional filters.

[0008] Furthermore, the heating module is located between the water pump and the washing pump, enabling instant heating of clean water to produce hot water or instant generation of high-temperature steam, eliminating the need to wait for the entire cavity to preheat, thereby shortening the washing and sterilization time. Moreover, by integrating the water and steam passages into a single design, the internal space of the entire bottle cleaner is saved.

[0009] In one embodiment of the invention, the spraying device includes a spray pipe in communication with a washing pump; The pipeline includes a hot water pipe and a steam pipe connecting the heating module and the washing pump. The steam pipe is fitted inside the hot water pipe, and a hot water channel for hot water circulation is formed between the steam pipe and the hot water pipe. The steam pipe extends at least partially into the interior of the spray pipe.

[0010] Compared with existing technologies, the technical effects achieved by this solution are as follows: This solution uses a composite pipeline structure in which a steam pipe is fitted inside a hot water pipe and a portion of the steam pipe extends into a spray pipe. On the one hand, by using steam to simultaneously heat the hot water, it effectively solves the problems of low heating plate power and slow heating in existing bottle washing machines, thereby improving heating efficiency. On the other hand, high-temperature hot water and steam are sprayed directly from the spray device, avoiding the situation where the bottom heating plate of existing bottle washing machines comes into contact with sewage and accumulates dirt, thus eliminating hygiene hazards at the source.

[0011] In one embodiment of the present invention, a slot is provided at the outlet of the washing pump of the spray pipe, and a snap-fit ​​component that mates with the slot is provided at the second outlet of the steam pipe. The snap-fit ​​component has a hollow structure.

[0012] Compared with existing technologies, the technical effects achieved by this solution are as follows: This solution achieves pipe clamping assembly by setting a slot at the spray pipe outlet and configuring a matching hollow clamping component at the second steam pipe outlet, thereby realizing quick assembly and disassembly and improving the convenience of assembly and maintenance. At the same time, the hollow structure can effectively reduce the resistance to medium flow, ensuring the normal delivery of fluid and steam. Moreover, the clamping fit is reliable in positioning and stable in connection, avoiding the possibility of pipe loosening during the operation of the bottle washing machine, thereby improving the stability and reliability of the bottle washing machine during operation.

[0013] In one embodiment of the invention, the steam pipe and / or the snap-fit ​​fitting are made of stainless steel.

[0014] Compared with existing technologies, the technical effects achieved by adopting this solution are as follows: The steam pipe and / or clamping parts are made of stainless steel, which gives the steam pipe and clamping parts excellent corrosion resistance, rust prevention and aging resistance, and can withstand the erosion of water vapor and media under washing conditions, thereby extending the service life of the steam pipe and clamping parts; at the same time, the stainless steel structure has high strength and is not easily deformed, ensuring that the clamping parts can be stable for a long time, thereby reducing the failure frequency and maintenance cost of the baby bottle washing machine.

[0015] In one embodiment of the present invention, the spraying device is provided with a first spraying arm and a plurality of second spraying arms; The spray pipe is located inside the first spray arm; Each of the plurality of second spray arms is provided with a first flushing pipe connected to the spray pipe; Multiple second spray arms are arranged around the first spray arm.

[0016] Compared with existing technologies, the technical effects achieved by this solution are as follows: In this solution, the spray pipe is built into the first spray arm, and multiple second spray arms are arranged around it and connected to the spray pipe through the first rinsing pipe, realizing multi-directional and full-coverage spray rinsing without cleaning dead corners, thereby improving the cleaning uniformity and cleaning effect of the bottle cleaner; at the same time, the pipeline integration layout is compact and reasonable, improving the internal space utilization of the bottle cleaner.

[0017] In one embodiment of the present invention, the washing pump is provided with a sewage inlet and a sewage outlet that are interconnected. The sewage inlet is connected to the washing chamber, and a sewage channel is formed between the sewage inlet and the sewage outlet.

[0018] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: In this solution, the washing pump is equipped with an interconnected sewage inlet and sewage outlet, forming an independent sewage channel between the sewage inlet and the sewage outlet to discharge the sewage in the inner tank. This gives the sewage in the inner tank an independent drainage path, thereby avoiding leakage and blockage at the joints. At the same time, the integrated drainage path reduces the need for external connecting pipelines, thereby simplifying the assembly process of the cleaning machine and improving the production efficiency of the cleaning machine.

[0019] In one embodiment of the present invention, a drain outlet is provided at the bottom of the inner liner, and a sewage inlet is at least partially fitted inside the drain outlet.

[0020] Compared with existing technologies, the technical effects achieved by this solution are as follows: In this solution, the sewage inlet and outlet of the washing pump are nested together to form a sewage channel, which has good sealing performance and prevents sewage leakage; at the same time, the sewage inlet is at least partially fitted inside the inlet, which simplifies the assembly method of the sewage inlet and outlet and improves the convenience of the assembly process.

[0021] In one embodiment of the invention, the cleaning device further includes a filter device disposed at the drain outlet, the filter device being used to filter the sewage discharged from the inner tank.

[0022] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: In this solution, a filter device is installed at the sewage inlet to filter impurities in the discharged sewage, preventing coarse debris from entering the washing pump and pipeline, thus avoiding blockage and wear problems in the washing pump and pipeline, ensuring the long-term smooth operation of the washing pump and pipeline, reducing the probability of failure and maintenance frequency, and extending the service life of the washing pump and pipeline.

[0023] In one embodiment of the present invention, the housing has a first receiving cavity and a second receiving cavity arranged adjacent to each other, the inner liner is installed in the first receiving cavity, and the cleaning device further includes: The drying fan is located inside the second receiving cavity; The second receiving cavity is positioned higher than the first receiving cavity, and the shell is provided with an air passage that communicates with the second receiving cavity. An air inlet that communicates with the air passage is opened on the first side wall of the inner liner near the second receiving cavity.

[0024] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: Traditional baby bottle cleaning equipment is equipped with a hot air duct that connects to the cleaning chamber in order to achieve steam sterilization and hot air drying functions. In order to prevent steam from entering the duct and damaging the fan and related heating components, existing solutions generally narrow the duct opening and design the duct as a bent structure of at least 180°, which increases the resistance during the hot air delivery process and affects the drying efficiency of the baby bottle cleaning equipment.

[0025] In this design, the drying fan is positioned higher than the cleaning chamber. Combined with the air passage between the shell and the inner liner, and the air inlet at the bottom of the inner liner, compared to the existing technology where the air duct is designed with at least a 180° bend, this design reduces the resistance during hot air delivery by decreasing the bend angle of the air passage, thereby improving the drying efficiency of the cleaning machine. At the same time, the second receiving chamber is positioned higher than the first receiving chamber, allowing the drying fan to be positioned higher than the inner cleaning chamber. During drying, hot air is blown into the cleaning chamber from top to bottom, preventing cleaning wastewater from flowing back into the drying fan and causing damage to it, thus improving the protection performance of the drying fan.

[0026] In one embodiment of the invention, the first sidewall has a lower portion near the bottom of the inner liner and an upper portion away from the bottom of the inner liner, and an air inlet is formed between the upper and lower portions.

[0027] Compared with existing technologies, the technical effects achieved by this solution are as follows: In this solution, the air inlet is located between the upper and lower parts of the first side wall. Compared with the structure where the air inlet is located near the bottom of the inner liner on the first side wall, this solution does not require additional dampers to block steam, simplifying the structure of the air passage and reducing assembly costs. At the same time, the temperature difference between the upper and lower areas inside the inner liner forms an orderly airflow circulation, reducing steam overflow. Furthermore, by placing the air inlet between the upper and lower parts of the first side wall, this solution avoids the problem of water easily seeping into the connection gap between the inner liner and the shell air passage, thus preventing leakage.

[0028] By adopting the technical solution of the present invention, the following technical effects can be achieved: This invention provides a baby bottle washing machine. By placing the heating module between the clean water path, water pump, and washing pump on the side of the water tank, compared to the traditional bottom immersion heating structure, the clean water path can achieve independent closed-loop heating. The heating module is entirely within the clean water path of the water tank, completely avoiding contact with the dirty water during the baby bottle washing process. This prevents scale and dirt residue from adhering to the heating module, and completely eliminates hygiene dead spots and potential hazards without the need for additional filters. Furthermore, the heating module's placement between the water pump and washing pump enables instant heating of clean water to produce hot water or instant generation of high-temperature steam, eliminating the need to wait for the entire cavity to preheat, thus shortening the washing and sterilization time. Moreover, by integrating the water path and steam path into a single design, the internal space of the entire baby bottle washing machine is saved. Attached Figure Description

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] like Figure 15 The diagram shown is a schematic diagram of a conventional baby bottle washing machine. In a traditional baby bottle washing machine, the water pump 2 is connected to the water tank 1, the heating plate 3 is directly installed in the inner tank, and the second washing pump 4 is connected to the drain pump 5 to discharge the sewage in the inner tank.

[0034] like Figures 1 to 14 As shown, this invention provides a baby bottle cleaning machine, which includes a housing 100, an inner tank 120, a water tank 130, and a cleaning device. The cleaning device includes a spray device 200, a washing pump 300, a water pump 400, and a heating module 500. Specifically, the spray device 200 is located inside the cleaning chamber of the inner tank 120. The washing pump 300 supplies water to the spray device 200. The water pump 400 is connected between the water tank 130 and the washing pump 300 via a pipe 700. The heating module 500 is located between the water pump 400 and the washing pump 300 and provides hot water or steam to the washing pump 300. The washing pump 300, the water pump 400, and the heating module are installed in an mounting compartment between the base of the housing 100 and the inner tank 120.

[0035] Understandably, this solution places the heating module 500 between the water pump 400 and the washing pump 300 and houses it in the installation compartment between the base and the inner tank 120, away from the sewage area of ​​the inner tank 120's cleaning chamber 122. Compared to the traditional bottom immersion heating structure, this avoids the heating module 500 directly contacting sewage and scale buildup. Furthermore, the heating module 500's placement in the clean water path between the water pump 400 and the washing pump 300 achieves independent closed-loop heating, ensuring that the heating module 500 remains within the clean water path of the water tank 130 throughout the process, completely avoiding contact with the dirty water during the bottle washing process. This prevents scale and dirt residue from adhering to the heating module 500, and eliminates the need for additional filters, thus completely resolving hygiene dead spots and potential hygiene hazards.

[0036] Furthermore, the heating module 500 is positioned between the water pump 400 and the washing pump 300, enabling instant heating of clean water to produce hot water or instant generation of high-temperature steam, eliminating the need to wait for the entire cavity to preheat, thereby shortening the washing and sterilization time. Moreover, by integrating the water and steam pathways into a single design, the internal space of the entire bottle cleaner is saved.

[0037] like Figures 1 to 12 As shown, in one embodiment of the present invention, the spray device 200 includes a spray pipe 210 communicating with the washing pump 300; the pipeline 700 includes a hot water pipe 710 and a steam pipe 720 communicating between the heating module 500 and the washing pump 300, the steam pipe 720 being sleeved inside the hot water pipe 710, and a hot water channel for hot water circulation being formed between the steam pipe 720 and the hot water pipe 710; wherein, the steam pipe 720 extends at least partially into the interior of the spray pipe 210.

[0038] Understandably, this solution, through the composite pipe 700 structure in which the steam pipe 720 is fitted inside the hot water pipe 710 and part of the steam pipe 720 extends into the spray pipe 210, effectively solves the problem of low heating plate power and slow heating in existing bottle washing machines by using steam to simultaneously heat the hot water, thereby improving heating efficiency. On the other hand, high-temperature hot water and steam are sprayed directly from the spray device 200, avoiding the situation where the bottom heating plate of the existing bottle washing machine comes into contact with sewage and grime, thus eliminating hygiene hazards at the source.

[0039] like Figures 4 to 10 As shown, in one embodiment of the present invention, the spray pipe 210 is provided with a slot at the outlet of the washing pump 300, and the second outlet of the steam pipe 720 is provided with a snap-fit ​​member 730 that cooperates with the slot; wherein, the snap-fit ​​member 730 has a hollow structure.

[0040] Understandably, this solution achieves quick assembly and disassembly of the pipeline 700 by setting a slot at the outlet of the spray pipe 210 and configuring a matching hollow snap-fit ​​component 730 at the second outlet of the steam pipe 720. This improves the convenience of assembly and maintenance. At the same time, the hollow structure can effectively reduce the resistance to medium flow, ensuring the normal delivery of fluid and steam. The snap-fit ​​method provides reliable positioning and a stable connection, preventing the pipeline 700 from becoming loose during the operation of the bottle cleaner, thereby improving the stability and reliability of the bottle cleaner during operation.

[0041] In one embodiment of the invention, the steam pipe 720 and / or the snap-fit ​​fitting 730 are made of stainless steel.

[0042] Understandably, the steam pipe 720 and / or the clamping component 730 in this solution are made of stainless steel, which gives both the steam pipe 720 and the clamping component 730 excellent corrosion resistance, rust prevention and aging resistance, and can withstand the erosion of water vapor and media under washing conditions, thereby extending the service life of the steam pipe 720 and the clamping component 730; at the same time, the stainless steel structure has high strength and is not easily deformed, ensuring that the clamping component 730 can be stable for a long time, thereby reducing the frequency of failure and maintenance costs of the baby bottle washing machine.

[0043] like Figures 5 to 12 As shown, in one embodiment of the present invention, the spray device 200 is provided with a first spray arm 220 and a plurality of second spray arms 230; a spray pipe 210 is disposed inside the first spray arm 220; any one of the plurality of second spray arms 230 is provided with a first rinsing pipe 240 communicating with the spray pipe 210; wherein, the plurality of second spray arms 230 are arranged around the first spray arm 220.

[0044] Understandably, in this solution, the spray pipe 210 is built into the first spray arm 220, and multiple second spray arms 230 are arranged around it and connected to the spray pipe 210 through the first rinsing pipe 240, which realizes multi-directional and full-coverage spray rinsing without cleaning dead corners, thereby improving the cleaning uniformity and cleaning effect of the baby bottle cleaner; at the same time, the integrated layout of the pipeline 700 is compact and reasonable, which improves the internal space utilization of the baby bottle cleaner.

[0045] like Figure 4 and Figure 6 As shown, in one embodiment of the present invention, the washing pump 300 is provided with a sewage inlet 310 and a sewage outlet 320 that are interconnected. The sewage inlet 310 is connected to the washing chamber 122, and a sewage channel is formed between the sewage inlet 310 and the sewage outlet 320.

[0046] Understandably, in this solution, the washing pump 300 is equipped with an interconnected sewage inlet 310 and sewage outlet 320. The sewage inlet 310 and sewage outlet 320 form an independent sewage channel to discharge the sewage in the inner tank 120, so that the sewage in the inner tank 120 has an independent drainage path, thereby avoiding leakage and blockage at the joints. At the same time, the integrated drainage path reduces the number of external connecting pipes 700, thereby simplifying the assembly process of the cleaning machine and improving the production efficiency of the cleaning machine.

[0047] In one embodiment of the present invention, the bottom of the inner liner 120 is provided with a drain outlet 123, and the sewage inlet 310 is at least partially fitted inside the drain outlet 123.

[0048] Understandably, in this solution, the sewage inlet 310 and the drain outlet 123 of the washing pump 300 are nested together to form a sewage channel, which has good sealing performance and prevents sewage leakage. At the same time, the sewage inlet 310 is at least partially fitted inside the inlet 620, which simplifies the assembly method of the sewage inlet 310 and the drain outlet 123 and improves the convenience of the assembly process.

[0049] like Figures 4 to 13 As shown, in one embodiment of the present invention, the cleaning device further includes a filter device 330 disposed at the drain outlet 123, the filter device 330 being used to filter the sewage discharged from the inner liner 120.

[0050] Understandably, this solution includes a filter device 330 at the sewage inlet 310 to filter impurities from the discharged sewage, preventing coarse debris from entering the washing pump 300 and pipeline 700, thus avoiding blockages and wear on the washing pump 300 and pipeline 700. This ensures the long-term smooth operation of the washing pump 300 and pipeline 700, reduces the probability of failure and maintenance frequency, and extends the service life of the washing pump 300 and pipeline 700.

[0051] like Figure 14 and Figure 15 As shown, the inner liner 120 has an installation groove 124 at the drain outlet 123, and the filter device 330 has a protrusion 331 that cooperates with the installation groove 124 so that the filter device 330 is installed at the drain outlet 123 in a snap-fit ​​manner.

[0052] like Figures 1 to 14As shown, in one embodiment of the present invention, the housing 100 has a first receiving cavity 140 and a second receiving cavity arranged adjacent to each other, the inner liner 120 is installed in the first receiving cavity 140, and the cleaning device further includes a drying fan 600, which is disposed in the second receiving cavity; wherein, the position of the second receiving cavity is higher than the position of the first receiving cavity 140, and the housing 100 is provided with an air passage 110 communicating with the second receiving cavity, and the inner liner 120 has an air inlet 121 communicating with the air passage 110 on the first side wall near the second receiving cavity. Figure 14 The blue arrows indicate the water flow path, the orange arrows indicate the steam and water flow path, and the red arrows indicate the air flow path.

[0053] Understandably, traditional baby bottle cleaning equipment has a hot air duct connecting the cleaning chamber 122 to achieve steam sterilization and hot air drying functions. To prevent steam from entering the duct and damaging the fan and related heating components, existing solutions generally narrow the duct opening and design the duct as a bend structure of at least 180°, which increases the resistance during the hot air delivery process and affects the drying efficiency of the baby bottle cleaning equipment. Figure 15 The blue arrows indicate the water flow path, and the red arrows indicate the air flow path.

[0054] In this design, the drying fan 600 is positioned above the cleaning chamber 122. Combined with the air passage 110 between the shell 100 and the inner liner 120, and the air inlet 121 at the bottom of the inner liner 120, compared to the existing technology where the air duct is designed with a bend of at least 180°, this design reduces the bending angle of the air passage 110, thereby reducing the resistance during hot air delivery and improving the drying efficiency of the cleaning machine. At the same time, the second receiving chamber is positioned higher than the first receiving chamber 140, so that the drying fan 600 is positioned higher than the inner liner 120. During drying, hot air is blown into the cleaning chamber 122 from top to bottom, preventing the backflow of cleaning wastewater into the drying fan 600 and causing damage to the drying fan 600, thus improving the protection performance of the drying fan 600.

[0055] like Figure 5 As shown, in one embodiment of the present invention, the air inlet 121 is formed on the first side wall near the bottom of the inner tank 120. During the washing process, the water accumulated at the bottom of the inner tank 120 forms a water seal effect on the air inlet 121 to prevent water vapor in the inner tank 120 from entering the second receiving cavity during the washing process and causing damage to the drying fan 600.

[0056] like Figure 2 , Figure 3 and Figure 12As shown, in one embodiment of the present invention, the first sidewall has a lower portion near the bottom of the inner liner 120 and an upper portion away from the bottom of the inner liner 120, and an air inlet 121 is formed between the upper portion and the lower portion.

[0057] Understandably, in this design, the air inlet 121 is located between the upper and lower parts of the first side wall. Compared to a structure where the air inlet 121 is located near the bottom of the inner liner 120 on the first side wall, this design eliminates the need for an additional damper to block steam, simplifying the structure of the air passage 110 and reducing assembly costs. At the same time, the temperature difference between the upper and lower areas inside the inner liner 120 creates an orderly airflow circulation, reducing steam overflow. Furthermore, by placing the air inlet 121 between the upper and lower parts of the first side wall, this design prevents water from easily seeping into the connection gap between the inner liner 120 and the air passage 110 of the shell 100, thus avoiding leakage.

[0058] like Figure 1 As shown, in one embodiment of the present invention, the baby bottle cleaner is equipped with a temperature sensor, and a control panel 810 is also provided on the outside of the housing 100. The control panel 810 includes a power button 811, a start / pause button 812, a quick clean button 813, a standard clean button 814, a fresh air storage / drying button 815, a steam sterilization button 816, and a display screen 817. An electrical control box 800 is provided at the bottom of the inner liner 120. The electrical control box 800 is electrically connected to the control panel 810, the temperature sensor, the water pump 400, the washing pump 300, the drying fan 600, and the heating module 500, so as to control the start and stop states of the water pump 400, the washing pump 300, the drying fan 600, and the heating module 500 through the control panel 810.

[0059] The following is a detailed explanation of how to clean baby bottles: Baby bottle washing machine structure description: This specific embodiment discloses a fully automatic baby bottle cleaning machine, which includes a shell 100, an inner tank 120, a water tank 130, a cleaning device, a control panel 810, and an electrical control box 800. The inner tank 120 internally defines a cleaning chamber 122. The cleaning device integrates four functional modules: spray cleaning, hot water and steam supply, wastewater discharge, and hot air drying. The water system, air system, and electrical control system of the baby bottle cleaning machine correspond one-to-one with the structures of the above embodiments. The assembly and working logic of each core component are as follows: Water system: Water tank 130 → Water pump 400 → Heating module 500 → Double-layer pipeline 700 (hot water pipe 710, steam pipe 720) → Washing pump 300 → Spray device 200, realizing dual water and gas supply for hot water washing and high-temperature steam disinfection; Steam pipe 720 is nested inside hot water pipe 710, and the two form a hot water channel in the interlayer. The end of steam pipe 720 is fixed to spray pipe 210 through a hollow snap-fit ​​connector 730, which is convenient to disassemble and install and does not obstruct the flow of medium; Sewage system: Sewage in the inner tank 120 → Filter device 330 filters impurities → Drain 123 → Sewage inlet 310 of washing pump 300 → Sewage channel → Sewage outlet 320 connected to external drain pipe for discharge; Sewage inlet 310 of washing pump 300 is fitted into drain 123. Drying system: The drying fan 600 is installed in the second receiving cavity of the housing 100 and the position of the drying fan 600 is higher than the inner liner 120.
