[0002] This application claims priority to Chinese patent application No. 202520160380.9, filed January 21, 2025, and Chinese patent application No. 202520561431.9, filed March 26, 2025, the entire contents of which are incorporated herein by reference.

[0003] Technical Field

[0004] This application belongs to the field of household appliance technology, specifically relating to a drying system, drying components, and a baby bottle cleaner. Background Technology

[0005] Baby bottle washer drying systems focus on the cleanliness and hygiene of baby care products, aiming to ensure that bottles are thoroughly washed and dried after use to eliminate bacteria and microorganisms, thereby protecting the baby's health. However, existing baby bottle washer systems have some shortcomings in drying, especially since components such as the fan are often installed at the bottom to reduce size. This can cause water or steam from the washing chamber to leak out along the fan duct, potentially damaging the fan. Furthermore, the small opening of the bottles results in poor drying inside. These problems urgently need to be addressed to improve the performance and safety of baby bottle washer systems. Summary of the Invention

[0006] This application provides a drying system for a baby bottle cleaner and a baby bottle cleaner, aiming to solve the problem that the air duct of the drying system of the existing baby bottle cleaner is prone to moisture.

[0007] To solve the above-mentioned technical problems, this application proposes a drying system for a baby bottle washing machine, including a hot air channel and a hot air assembly. The hot air channel includes a drying channel and a U-shaped air duct with its opening facing downwards. One end of the U-shaped air duct is connected to the hot air assembly, and the other end of the U-shaped air duct is connected to the drying channel. The drying channel is provided with a plurality of air outlets for discharging hot air.

[0008] In one embodiment, the hot air assembly includes a hot air fan and a heater, the heater being located between the outlet of the hot air fan and the inlet of the U-shaped air duct. Based on this design, by placing the heater between the outlet of the hot air fan and the inlet of the U-shaped air duct, the cold air blown by the fan is effectively converted into hot air, improving drying efficiency and uniformity. Simultaneously, the high-temperature hot air kills bacteria and microorganisms in the baby bottle, ensuring the baby's health. Furthermore, this arrangement helps prevent backflow and protects the fan from damage due to moisture, thereby extending the equipment's lifespan and saving energy.

[0009] In one embodiment, both the hot air fan and the heater are located below the U-shaped air duct.

[0010] In one embodiment, the drying channel includes an air inlet chamber that communicates with the air inlet end of the drying channel, and a U-shaped air duct with an air outlet end, the air inlet chamber and the air outlet end of the U-shaped air duct being correspondingly arranged. Based on the above scheme, the drying channel includes an air inlet chamber that communicates with the air inlet end of the drying channel, while the U-shaped air duct has an air outlet end, the air inlet chamber and the air outlet end of the U-shaped air duct being correspondingly arranged. This design allows hot air to enter the air chamber of the drying channel from the air outlet end of the U-shaped air duct, be evenly distributed through the air inlet chamber, and then blown out through the air outlet of the drying channel, forming an effective hot air circulation. This ensures that the baby bottle is heated evenly during the drying process, improves drying efficiency, reduces heat loss, and optimizes the drying effect.

[0011] In one embodiment, the outlet end of the U-shaped air duct is located above the inlet end. Based on this design, the outlet end of the U-shaped air duct is positioned above the inlet end. This design utilizes the principle of hot air rising, allowing the hot air to rise naturally within the U-shaped air duct, thereby more effectively delivering the hot air to the drying channel and enhancing drying efficiency. Simultaneously, this layout helps reduce backflow and turbulence of hot air during the drying process, ensuring that the hot air can be concentrated and continuously dried on the baby bottles, improving the uniformity and effectiveness of the drying process.

[0012] In one embodiment, the diameter of the air inlet cavity gradually increases from the end closer to the drying channel to the end farther away from the drying channel. Based on the above scheme, the design of the air inlet cavity gradually increasing in diameter from the end closer to the drying channel to the end farther away from the drying channel can make the airflow in the air duct system more stable, reduce the energy loss of the airflow when passing through the diameter change section, thereby improving the energy efficiency of the entire drying system.

[0013] In one embodiment, the drying channel is annular. Based on the above scheme, the annular shape of the drying channel allows the baby bottles to be placed around it. Since the drying channel has air vents, the annular distribution not only accelerates the hot air circulation speed, thereby speeding up the drying process, but also maximizes space utilization.

[0014] This application also proposes a baby bottle washing machine, including the drying system of the baby bottle washing machine as described above.

[0015] In one embodiment, the bottle washing machine further includes a body and a washing chamber located inside the body, wherein the U-shaped air duct and the hot air assembly are both located outside the washing chamber.

[0016] In one embodiment, the drying channel is located at the bottom of the cleaning chamber. Based on the above scheme, the U-shaped air duct is located outside the cleaning chamber, while the drying channel is located at the bottom of the cleaning chamber. This layout spatially separates the drying process from the cleaning process, which helps to keep the drying channel dry and clean, while avoiding the impact of water vapor or residue generated during cleaning on the drying effect.

[0017] This application also proposes a drying component for a baby bottle washing machine, comprising:

[0018] The air duct includes an air inlet, a first air outlet, and a second air outlet;

[0019] A fan is provided at the air inlet and is used to blow air into the duct.

[0020] A heating element for heating the air entering the duct;

[0021] The second air outlet is positioned higher than the first air outlet.

[0022] In one embodiment, the duct includes at least two second air outlets.

[0023] In one embodiment, at least two of the second air outlets are at different heights.

[0024] In one embodiment, the diameter of the second air outlet is smaller than the diameter of the first air outlet.

[0025] In one embodiment, an anti-backflow air duct is provided between the air inlet and the first air outlet.

[0026] In one embodiment, the backflow prevention duct includes a bend.

[0027] This application also proposes a baby bottle washing machine, including the drying component of the baby bottle washing machine as described above.

[0028] In one embodiment, the bottle washing machine further includes a first shelf and a second shelf, the second shelf being higher than the first shelf, at least a portion of the second air outlet being located between the first shelf and the second shelf, and the second air outlet being closer to the second shelf.

[0029] In one embodiment, at least a portion of the first air outlet is located between the first shelf and the second shelf, and the first air outlet is positioned closer to the first shelf.

[0030] In one embodiment, the bottle washing machine further includes a first spray assembly corresponding to the first shelf and a second spray assembly corresponding to the second shelf.

[0031] The beneficial effects of this application are as follows:

[0032] This application provides a drying system for a baby bottle washer and the baby bottle washer itself. Through a U-shaped air duct layout and a unidirectional hot air flow design, utilizing the natural law of rising hot air and structural elevation differences, it prevents cold air or moisture from flowing back into the hot air assembly, ensuring continuous unidirectional hot air flow. This improves drying efficiency and effectiveness while protecting the hot air assembly. Furthermore, by connecting the hot air assembly to one end of the U-shaped air duct, hot air can directly enter the baby bottle, creating forced convection and enhancing the drying effect inside the bottle, ensuring it is thoroughly dry before use. Several air vents on the drying channel facilitate unidirectional hot air flow, preventing backflow, improving drying efficiency, and accelerating the drying speed. This allows the baby bottles to be used quickly after washing, while also preventing bacterial growth inside the bottles due to prolonged moisture. Attached Figure Description

Embodiments of the present invention

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely for explaining this application and are not intended to limit this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the protection scope of this application.

[0048] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0049] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0050] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0051] As shown in Figure 1, this embodiment provides a drying system for a baby bottle washing machine, including a hot air channel and a hot air assembly. The hot air channel includes a drying channel and a U-shaped air duct with its opening facing downwards. One end of the U-shaped air duct is connected to the hot air assembly, and the other end of the U-shaped air duct is connected to the drying channel. The drying channel is provided with a plurality of air outlets for discharging hot air.

[0052] The hot air assembly includes a hot air fan and a heater, with the heater located between the outlet of the hot air fan and the inlet of the U-shaped air duct. Specifically, the hot air fan, heater, and U-shaped air duct form a continuous airflow path. The hot air fan generates cold air, which is then heated by the heater before finally entering the U-shaped air duct.

[0053] Furthermore, both the hot air fan and the heater are located below the U-shaped air duct. Specifically, the air generated by the hot air fan is first heated by the heater and then flows upward into the U-shaped air duct.

[0054] To achieve effective hot air circulation, based on any of the above-mentioned solutions, the drying channel includes an air inlet chamber connected to the air inlet end of the drying channel. The U-shaped air duct has an air outlet end, with the air inlet chamber and the air outlet end of the U-shaped air duct corresponding to each other. The air outlet end of the U-shaped air duct is located above the air inlet end of the U-shaped air duct. Specifically, the air inlet chamber of the drying channel is connected to the air inlet end of the drying channel, and hot air flows from the air inlet chamber into the air inlet end of the drying channel, thus entering the drying channel. Simultaneously, the air outlet end of the U-shaped air duct is located above the air inlet end of the U-shaped air duct, allowing the hot air to rise naturally and be discharged through the air outlet end of the U-shaped air duct. Since the air outlet end of the U-shaped air duct is opposite to the air inlet chamber of the drying channel, after the hot air enters the air inlet chamber of the drying channel from the air outlet end of the U-shaped air duct, it flows along the drying channel and is then discharged through the air outlet of the drying channel.

[0055] Furthermore, the diameter of the air inlet chamber gradually increases from the end closest to the drying channel to the end furthest from the drying channel. Specifically, the air inlet chamber is integrated with the drying channel, and the air inlet chamber is funnel-shaped, with the end with the larger diameter facing the air outlet of the U-shaped air duct, and the end with the smaller diameter connected to the drying channel.

[0056] To accelerate the circulation of hot air, the drying channel is circular, based on any of the above-mentioned solutions. Specifically, the drying channel has several air outlets. When the baby bottle is placed upside down above the drying channel, each air outlet faces the inside of the bottle, allowing the hot air to precisely dry the inside of the bottle.

[0057] As shown in Figure 3, this embodiment provides a baby bottle washing machine, including the drying system of the baby bottle washing machine described above. Furthermore, the baby bottle washing machine also includes a body and a washing chamber located within the body. The U-shaped air duct and the hot air assembly are both located outside the washing chamber. Specifically, the U-shaped air duct is located on the left side of the washing chamber, and the hot air assembly is located below the washing chamber. The drying channel is located at the bottom of the washing chamber.

[0058] The following is a further explanation of the working principle of this application: The hot air fan generates airflow, which is heated by the heater and then sent to the air inlet of the U-shaped air duct. Since the air outlet of the U-shaped air duct is designed above the air inlet of the U-shaped air duct, the hot air rises naturally and flows from the air outlet of the U-shaped air duct into the air inlet chamber corresponding to the air outlet of the U-shaped air duct. Then the hot air enters the drying channel and is evenly distributed through the air outlet holes set on the drying channel to dry the baby bottle.

[0059] Please refer to Figures 5, 6 and 7 together. This application embodiment provides a baby bottle cleaning machine 100, which includes a body 20. Components such as a washing pump and a drain pump (not shown in the figures) can be installed on the body 20.

[0060] The baby bottle cleaning machine 100 provided in this application embodiment also includes a cover 10, which is connected to the body 20 and can be enclosed to form a cleaning chamber 101.

[0061] The baby bottle cleaning machine 100 provided in this application embodiment also includes a spray device 30, which can be disposed in the cleaning chamber 101 and can clean the items to be cleaned in the cleaning chamber 101.

[0062] In one embodiment, the spray device 30 includes a shelf for placing items to be cleaned and a spray assembly for spraying and cleaning the items to be cleaned.

[0063] In one embodiment, the shelf includes a first shelf and a second shelf, which are spaced apart. The first and second shelves can hold different items. The direction of the spacing between the second and first shelves can be specifically set according to the product type. The spacing direction between the second and first shelves can be vertical, horizontal, or other similar.

[0064] For example, the second placement rack and the first placement rack are arranged at a distance from each other in the vertical direction. For instance, the second placement rack is higher than the first placement rack.

[0065] In one embodiment, the spray assembly includes a first spray assembly 33 and a second spray assembly 34, which are spaced apart and the spacing direction is the same as the spacing direction of the first and second storage racks. The first spray assembly 33 is correspondingly disposed to the first storage rack 31, and can spray washing water onto the items to be cleaned on the first storage rack 31, thereby cleaning the items. The second spray assembly 34 is correspondingly disposed to the second storage rack 32, and can spray washing water onto the items to be cleaned on the second storage rack 32, thereby cleaning the items.

[0066] It is understandable that items that are wet after washing cannot be used immediately and are prone to attracting dirt, so they need to be dried.

[0067] The bottle washing machine 100 provided in this application embodiment also includes a drying component 40 installed on the machine body 20. When the bottle washing machine 100 dries the items, hot air is blown into the washing chamber 101 of the bottle washing machine 100 by the drying component 40, so as to dry the washed items (items to be dried).

[0068] However, the inventors discovered that in the related technology, when the drying component 40 of the baby bottle washing machine dries the items to be washed, the drying component 40 of the baby bottle washing machine generates hot air that is blown into the washing chamber 101 through the air outlet, resulting in low drying efficiency.

[0069] Therefore, this application provides a drying component 40 for a baby bottle washing machine that can improve drying efficiency.

[0070] Please refer to Figures 8 and 9 together. The drying assembly 40 of the baby bottle washing machine provided in this embodiment includes a fan 7. The fan 7 can introduce air into the drying assembly 40 of the baby bottle washing machine, that is, blow air into the drying assembly 40 of the baby bottle washing machine to form a breeze. It should be noted that breeze can refer to flowing air, hot air refers to hot air, and cold air refers to cold air.

[0071] The drying assembly 40 of the baby bottle washing machine provided in this application embodiment also includes a heating element 8, which can generate heat. The heating element 8 is used to heat the air blown into the drying assembly 40 of the baby bottle washing machine by the fan 7 to form hot air.

[0072] In one embodiment, the heating element 8 can be heated by electrical energy.

[0073] The drying assembly 40 of the baby bottle washing machine provided in this application embodiment also includes an air duct 11, into which air heated by the heating element 8 can enter.

[0074] For example, the duct 11 includes an air inlet 301, and a fan 7 is disposed at the air inlet 301, allowing the fan 7 to blow air into the duct 11 through the air inlet 301. A heating element 8 is disposed on the side of the fan 7 facing the air inlet 301, thereby heating the air blown by the fan 7 from the air inlet 301 into the duct 11, forming hot air. In one embodiment, the heating element 8 can be disposed between the fan 7 and the duct 11, thereby heating the air entering the duct 11.

[0075] In one embodiment, the heating element 8 may be disposed at the outlet of the fan 7.

[0076] In one embodiment, the heating element 8 may be disposed at the air inlet 301.

[0077] In one embodiment, the heating element 8 may include a heating channel connecting the air inlet 301 and the outlet of the fan 7.

[0078] In one embodiment, the duct 11 further includes a first air outlet 302 and a second air outlet 303 spaced apart. Exemplarily, the first air outlet 302 and the second air outlet 303 are spaced apart along a first direction (the Z direction in FIG8). For example, the first direction can be a vertical direction.

[0079] For example, the second air outlet 303 is higher than the first air outlet. In this way, the air duct can blow hot air to positions at different heights through the first air outlet 302 and the second air outlet 303, so that items at different heights or at different heights can be blown with hot air at the same time, which helps to improve drying efficiency.

[0080] Therefore, the drying component 40 of the baby bottle washing machine provided in this application is beneficial to improving drying efficiency.

[0081] For example, please refer to Figures 8, 9 and 10 together. The first air outlet 302 and the second air outlet 303 can blow hot air onto the items to be dried on the shelves at different heights.

[0082] For example, the first air outlet 302 can blow hot air toward the items to be dried on the first shelf 31, and the second air outlet 303 can blow hot air toward the items to be dried on the second shelf 32.

[0083] In one embodiment, at least a portion of the first air outlet 302 is located between the first shelf 31 and the second shelf 32, and the first air outlet 302 is disposed closer to the first shelf 31.

[0084] In this way, the air duct 11 can blow hot air to the items to be dried on the first shelf 31 through the first air outlet 302.

[0085] In one embodiment, at least a portion of the second air outlet 303 is located between the first shelf 31 and the second shelf 32, and the second air outlet 303 is closer to the second shelf 32.

[0086] In this way, the air duct 11 can blow hot air onto the items to be dried on the second shelf 32 through the second air outlet 303. In one embodiment, referring to Figures 9, 10, and 11, the machine body 20 is provided with a first ventilation hole 201 and a second ventilation hole 202. The first ventilation hole 201 is connected to the first air outlet 302, and the second ventilation hole 202 is connected to the second air outlet 303. In this way, the air duct 11 can blow hot air into the machine body 20 through the first ventilation hole 201, and thus directly blow hot air onto the items to be dried on the first shelf 31, thereby improving drying efficiency. In addition, the air duct 11 can blow hot air into the machine body 20 through the second ventilation hole 202, and thus directly blow hot air onto the items to be dried on the second shelf 32, thereby improving drying efficiency.

[0087] In some embodiments, please continue to refer to Figures 8 and 9, the opening direction of the air inlet 301 is perpendicular to the opening direction of the first air outlet 302. For example, the opening direction of both the air inlet 301 and the opening direction of the first air outlet 302 are perpendicular to the first direction (the spacing direction between the first air outlet 302 and the second air outlet 303).

[0088] The opening direction of the air inlet 301 can be parallel to the Y direction in Figure 8, and the opening direction of the first air outlet 302 can be parallel to the X direction in Figure 9.

[0089] In this way, the air duct 11 can change the airflow direction of the hot air, thus adapting to the structure and spatial layout of the bottle washing machine 100, making it highly adaptable.

[0090] In one embodiment, the opening direction of the first air outlet 302 is the same as the opening direction of the second air outlet 303.

[0091] In one embodiment, the diameter of the air inlet 301 is larger than the diameters of the first air outlet 302 and the second air outlet 303, that is, the opening area of ​​the air inlet 301 is larger than the opening areas of the first air outlet 302 and the second air outlet 303. The duct 11 includes a variable-diameter air channel 304, which is located between the air inlet 301 and the first air outlet 302, and between the air inlet 301 and the second air outlet 303. In this way, the hot air entering the duct 11 from the air inlet 301 can increase its velocity after passing through the variable-diameter air channel 304, thereby increasing the velocity of the hot air discharged through the first air outlet 302 and the second air outlet 303.

[0092] In one embodiment, the variable diameter air duct 304 is directly connected to the air inlet 301.

[0093] In some embodiments, the diameter of the second air outlet 303 is smaller than the diameter of the first air outlet 302, that is, the opening area of ​​the second air outlet 303 is smaller than the opening area of ​​the first air outlet 302. Since hot air has a lower density and tends to rise more easily, the drying assembly 40 of the bottle washing machine in this embodiment of the application makes the diameter of the second air outlet 303 smaller than the diameter of the first air outlet 302, allowing hot air to be easily discharged from the lower-height first air outlet.

[0094] The inventors discovered that the air inside the body 20 is humid, and the air inside the body 20 flows back to the air inlet 301, which can easily damage the fan 7 and the heating element 8.

[0095] In some embodiments, the duct 11 further includes a backflow prevention duct 305, which is located between the air inlet 301 and the first air outlet 302. This helps to prevent air inside the body 20 from flowing back from the first air outlet to the air inlet 301 when the fan is not working, thereby improving safety.

[0096] In one embodiment, the backflow prevention duct 305 includes a bend 3052, which can prevent air backflow.

[0097] In one embodiment, the variable diameter air duct 304 is located between the anti-backflow air duct 305 and the air inlet 301.

[0098] The anti-backflow air duct 305 includes a first air duct section 3051, a bend section 3052, and a second air duct section 3053 connected in sequence. The first air duct section 3051 is connected to the air inlet 301, and the second air duct section 3053 is connected to the first air outlet 302.

[0099] In one embodiment, the first air duct section 3051 and the second air duct section 3053 are parallel.

[0100] In one embodiment, both the first air duct section 3051 and the second air duct section 3053 extend in a vertical direction (first direction).

[0101] Please continue to refer to Figures 8 and 9. In some embodiments, the duct 11 includes at least two second air outlets 303, that is, there are multiple second air outlets 303.

[0102] In one embodiment, at least two second air outlets 303 may be spaced apart along a second direction (the X direction in Figure 8), the second direction being perpendicular to the first direction.

[0103] In this way, the drying component 40 of the baby bottle washing machine provided in this application embodiment can further increase the blowing position of the air duct 11, so that more parts of the items to be dried can be blown by hot air at the same time, which is conducive to further improving the drying efficiency.

[0104] In one embodiment, at least two second air outlets 303 are spaced apart along a first direction (the Z direction in Figure 8).

[0105] Similarly, this setting helps to further increase the air blowing position of the air duct 11, so that more parts of the items to be dried can be blown by hot air at the same time, which helps to further improve drying efficiency.

[0106] For example, the first direction can be vertical, meaning that at least two second air outlets 303 are at different heights. This arrangement allows the air duct 11 to blow hot air to more positions at different heights, enabling more positions at different heights of the items to be dried, or more items at different heights, to be blown by hot air simultaneously, thus improving drying efficiency.

[0107] In some other embodiments, at least two second air outlets 303 are spaced apart along both the first and second directions. Similarly, this arrangement helps to further increase the airflow position of the air duct 11, allowing more areas of the items to be dried to be simultaneously exposed to hot air, which helps to further improve drying efficiency.

[0108] Please continue to refer to Figure 9. In some embodiments, the air duct 11 includes an extension air duct 306, which is located between the air inlet 301 and the second air outlet 303. Hot air at the air inlet 301 can flow to the second air outlet 303 through the extension air duct 306.

[0109] In one embodiment, the extended air duct 306 is connected to the anti-backflow air duct 305. Hot air at the air inlet 301 can enter the extended air duct 306 through the anti-backflow air duct 305, and then flow to the second air outlet 303 through the extended air duct 306.

[0110] In one embodiment, the extended air duct 306 is connected to the bend 3052 of the anti-backflow air duct 305 and the connection point of the second air duct section 3053.

[0111] In one embodiment, the extended air duct 306 corresponds to the second air duct segment 3053. The extended air duct 306 and the second air duct segment 3053 extend in the same direction.

[0112] Please refer to Figure 9. In some embodiments, the inner wall of the blower duct is provided with a diversion section 12, which is located at the connection between the extended air duct 306 and the anti-backflow air duct 305.

[0113] In one embodiment, the diversion portion 12 protrudes toward the bend portion 3052 of the anti-backflow duct 305. The bend portion 3052 includes a first edge 3054 and a second edge 3055 spaced apart along a first direction (Z direction in FIG9). Along the first direction, the diversion portion 12 is located between the first edge 3054 and the second edge 3055.

[0114] In this way, the diversion section 12 can disperse the hot air at the bend section 3052 into two parts, one part can flow to the first air outlet 302 and the other part can flow to the second air outlet, so that hot air can be blown out from both the first air outlet 302 and the second air outlet 303.

[0115] In one embodiment, the dimension of the diverter 12 in the first direction gradually decreases along the direction close to the bend 3052.

[0116] In this way, the diversion section 12 can guide the hot air of the bending section 3052, making it easier for the hot air of the bending section 3052 to be dispersed into two parts.

[0117] In some embodiments, the side of the diverter 12 facing the second air outlet 303 is a concave arc surface. In this way, the diverter 12 can make it easier for hot air to flow towards the second air outlet 303, thereby improving the airflow guiding effect.

[0118] In some embodiments, the side of the diverter 12 facing the first air outlet 302 is a concave arc surface. In this way, the diverter 12 can make it easier for hot air to flow towards the first air outlet 302, thereby improving the airflow guiding effect.

[0119] In some embodiments, the sides of the diverter 12 facing the second air outlet 303 and the sides facing the first air outlet 302 are both concave arc surfaces. In this way, the diverter 12 can make it easier for hot air to flow towards the second air outlet 303 and the first air outlet 302, thereby improving the airflow guiding effect.

[0120] Please continue referring to Figure 9. In some embodiments, the first edge 3054 is closer to the first air outlet 302 than the second edge 3055. That is, the edge of the bent portion 3052 facing the first air outlet 302 is the second edge 3055, and the edge of the bent portion 3052 facing the second air outlet 303 is the first edge.

[0121] In one embodiment, the opening area of ​​the first air outlet 302 is smaller than the opening area of ​​the second air outlet 303, and along the first direction, the distance between the diversion part 12 and the first edge 3054 is smaller than the distance between the diversion part 12 and the second edge 3055.

[0122] In one embodiment, the area of ​​the first air outlet 302 is larger than the area of ​​the second air outlet 303, and along the first direction, the distance between the diversion portion 12 and the first edge 3054 is greater than the distance between the diversion portion 12 and the second edge 3055.

[0123] In one embodiment, the area of ​​the first air outlet 302 is equal to the area of ​​the second air outlet 303, and along the first direction, the distance between the diversion portion 12 and the first edge 3054 is equal to the distance between the diversion portion 12 and the second edge 3055.

[0124] In this way, the drying component 40 of the baby bottle washing machine can distribute hot air as evenly as possible to the first air outlet 302 and the second air outlet 303, which is beneficial to improving the drying effect.

[0125] Please refer to Figures 8 and 9. The drying component 40 of the bottle washer may include a mounting hole 307, so that the drying component 40 of the bottle washer can be connected to the body 20 through the mounting hole 307.

[0126] In one embodiment, mounting hole 307 is provided on the blower pipe.

[0127] It is understood that the bottle washing machine 100 provided in this application embodiment has the same or similar technical effects as the drying component 40 of the bottle washing machine in any of the above embodiments, and will not be described again here.

[0128] This application is not limited to the above-described embodiments. Under the premise of no contradiction, the solutions can be combined arbitrarily. Anyone can derive other forms of products under the guidance of this application. However, no matter what changes are made in their shape or structure, all technical solutions that fall within the scope of the claims of this application shall fall within the protection scope of this application.
