[0061] As shown in Figures 1 to 6, this embodiment provides a baby bottle cleaning machine with an integrated cleaning pump and drain pump, comprising:

[0062] The machine body 1 has a cleaning chamber 11 inside, and a drain outlet is provided at the bottom of the cleaning chamber 11; and,

[0063] A cleaning pump 2 and a drain pump 3 are disposed inside the body 1 and located below the drain outlet. The drain end of the cleaning pump 2 is connected to the cleaning chamber 11, and the drain end of the drain pump 3 is connected to the outside. An intermediate water tank 4 is provided between the water inlet end of the cleaning pump 2 and the water inlet end of the drain pump 3. The upper part of the intermediate water tank 4 is connected to the drain outlet, and the lower part of the intermediate water tank 4 is provided with a first drain hole 41 connecting the cleaning pump 2 and a second drain hole 42 connecting the drain pump 3. The water inlet end of the cleaning pump 2, the water inlet end of the drain pump 3, and the intermediate water tank 4 are integrally formed.

[0064] In this embodiment, as shown in Figure 3, a hollow column 12 is provided inside the washing chamber 111, and the drain end of the cleaning pump 2 is connected to the hollow column 12. The bottle cleaner includes a cleaning state and a draining state. When the bottle cleaner is in the cleaning state, the cleaning pump 2 is working and the drain pump 3 is not working. The cleaning pump 2 pumps the water flowing into the intermediate water tank 4 into the hollow column 12 located in the cleaning chamber 11. The hollow column 12 is provided with a bottle support 13, a nipple support, and a spray arm for cleaning bottles and nipples. Afterward, the water falls into the cleaning chamber 11 and then enters the intermediate water tank 4 from the cleaning chamber 11. When the bottle cleaner is in the draining state, the drain pump 3 is working and the cleaning pump 2 is not working. After the drain pump 3 starts working, it discharges the water in the intermediate water tank 4 outward.

[0065] In this embodiment, as shown in Figure 1, the cleaning pump 2 and the drain pump 3 are arranged vertically. Specifically, the intermediate water tank 4 is a circular tank that extends from top to bottom. The first drain hole 41 and the second drain hole 42 are both located on the side wall of the intermediate water tank 4, and the axis of the first drain hole 41 and the axis of the second drain hole 42 are perpendicular to each other.

[0066] In this embodiment, the drain outlet is provided with a downwardly extending annular interface 113, and the upper end of the intermediate water tank 4 is inserted into the annular interface 113 and sealed to it. Specifically, it can be configured to be sealed by a sealing ring.

[0067] In this embodiment, as shown in Figures 2 and 6, to facilitate the fixing of the cleaning pump 2 and the drain pump 3 within the body 1, both the cleaning pump 2 and the drain pump 3 are provided with connecting seats 5. The lower side of the cleaning chamber 11 is provided with several downward-extending connecting posts 14 that correspond one-to-one with each connecting seat 5. Each connecting seat 5 is fixedly connected to its corresponding connecting post 14. Specifically, both the cleaning pump 2 and the drain pump 3 are provided with a connecting seat 5, and there are two connecting posts 14. The two connecting posts 14 are respectively fixedly connected to the two connecting seats 5. The drain end of the cleaning pump 2 extends upward and communicates with the lower end of the hollow column 12.

[0068] To reduce vibrations caused by the cleaning pump 2 or drainage pump 3 during operation, a vibration damping pad 6 is provided between each connecting seat 5 and its corresponding connecting column 14. During operation, the vibration damping pad 6 effectively reduces vibration and noise.

[0069] In one specific embodiment of the above solution, the connecting seat 5 has an arc-shaped hole with an opening on one side. The vibration damping pad 6 is located inside the arc-shaped hole, with its upper and lower parts abutting against the upper and lower sides of the connecting seat 5, respectively. Specifically, the diameters of the upper and lower parts of the vibration damping pad 6 are larger than the diameter of the arc-shaped hole, allowing the middle part of the vibration damping pad 6 to be inserted into the arc-shaped hole from the opening. The vibration damping pad 6 has a insertion hole, and the lower end of the connecting post 14 is inserted into the insertion hole.

[0070] In this embodiment, as shown in Figures 3 and 4, the cleaning chamber 11 includes a washing chamber 111 and a heating chamber 112 located at the bottom of the washing chamber 111. The drain outlet is located at the bottom of the heating chamber 112. Specifically, the hollow column 12, the bottle holder 13, and the spray arm are all disposed within the washing chamber 111. A drainer 7 is disposed between the bottom of the washing chamber 111 and the heating chamber 112. The upper end of the drainer 7 communicates with the bottom of the washing chamber 111, and the lower end of the drainer 7 has a drainage channel extending downward and inserted into the intermediate water tank 4. A drain mesh 711 with a small diameter is disposed on the side wall of the drainage channel near the first drain hole 41, which is used to filter impurities when the cleaning pump 2 is working. A through hole 712 with a larger diameter is disposed on the side wall of the drainage channel near the second drain hole 42, so that the filtered material can be discharged when the drain pump 3 is working. A gap is provided between the drainage channel and the intermediate water tank 4, so that water can enter the heating chamber 112.

[0071] Working principle explanation:

[0072] The inlet end of the cleaning pump 2, the inlet end of the drain pump 3, and the intermediate water tank 4 are integrally formed, and the included angle between the cleaning pump 2 and the drain pump 3 is 90 degrees, which facilitates installation and processing. When the cleaning pump 2 is working, the drain pump 3 is not working, and the cleaning pump 2 circulates the water entering the intermediate water tank 4 into the cleaning chamber 11. When the drain pump 3 is working, the cleaning pump 2 is not working, and the drain pump 3 discharges the water entering the intermediate water tank 4 to the outside.

[0073] Please refer to 7. This application provides a cleaning machine. The cleaning machine includes a body with a cleaning chamber. The cleaning machine uses washing water to clean the items to be cleaned inside the cleaning chamber. The items to be cleaned can be clothes, tableware, baby bottles, etc.

[0074] In one embodiment, the cleaning machine can be a washing machine, dishwasher, baby bottle cleaner, etc.

[0075] During the cleaning process of the washing machine, a washing pump is typically used to circulate the washing water in the washing chamber, and a drain pump is used to discharge the wastewater after washing. In one embodiment, the washing pump and the drain pump are respectively located at the bottom of the machine body.

[0076] The inventors discovered that in related technologies, the cleaning pump and drainage pump are connected in parallel along the axial direction, occupying a large amount of space. This may affect the overall layout of the cleaning machine, causing difficulties in the design and manufacturing of the entire machine.

[0077] Referring to Figure 8, to solve the above-mentioned technical problems, in this application, the cleaning pump includes a cleaning pump housing 10, and the drain pump includes a drain pump housing 20 connected to the cleaning pump housing 10. The cleaning pump housing 10 has a first axis 001 extending along a first direction (the X direction in Figure 7), and the drain pump housing 20 has a second axis 002 extending along a second direction (the Y direction in Figure 7). The first direction intersects the second direction; that is, the extension direction of the first axis 001 of the cleaning pump housing 10 intersects the extension direction of the second axis 002 of the drain pump housing 20. This helps to reduce the axial dimensions of the cleaning pump housing 10 along both the first axis 001 and the second axis 002, thereby reducing the space occupied.

[0078] In one embodiment, the second axis 002 is lower than the first axis 001, so that the position of the drain pump housing 20 is lower than the position of the cleaning pump housing 10, making it easier for washing water to enter the drain pump and preventing the used washing water from accumulating in the cleaning pump, thus facilitating the discharge of the used washing water through the drain pump.

[0079] Referring to Figure 9, in one embodiment, the first direction is perpendicular to the second direction, that is, the extension direction of the first axis 001 of the cleaning pump housing 10 is perpendicular to the extension direction of the second axis 002 of the drain pump housing 20.

[0080] Please continue to refer to Figures 8 and 9. In some embodiments, the baby bottle cleaning machine with the cleaning pump and drain pump integrated in this application embodiment also includes a water inlet shell 30. The water inlet shell 30 is connected to the cleaning pump shell 10 and the drain pump shell 20 respectively. The water inlet shell 30 has a water inlet cavity 301 and a water inlet hole 302 communicating with the water inlet cavity 301.

[0081] In one embodiment, the cleaning pump housing 10 has a water outlet chamber 101 and a water outlet hole 102 communicating with the water outlet chamber 101, the drainage pump housing 20 has a sewage discharge chamber 201 and a sewage discharge hole 202 communicating with the sewage discharge chamber 201, and the water inlet chamber 301 is communicating with the water outlet chamber 101 and the sewage discharge chamber 201 respectively.

[0082] In this way, the bottle cleaning machine provided in this application embodiment can use the water inlet chamber 301 of the water inlet shell 30 to connect with the water outlet chamber 101 of the cleaning pump shell 10 and the sewage discharge chamber 201 of the drain pump shell 20 respectively, which can reduce the number of connecting channels and simplify the structure.

[0083] In one embodiment, the drain hole is oriented in the same direction as the first direction.

[0084] In one embodiment, the drain hole is oriented in the same direction as the second direction.

[0085] In one embodiment, the drain hole is oriented in the same direction as the water inlet 302.

[0086] Understandably, the orientation of the drain hole can be set in various ways to easily adapt to the structural layout of the cleaning machine, making it highly adaptable.

[0087] In one embodiment, the water outlet 102 and the water inlet 302 face the same direction. This facilitates the circulation of washing water in and out of the bottle washing machine and makes the pipeline layout easier.

[0088] In some embodiments, the water inlet chamber 301 has a third axis communicating along a third direction (the Z direction in FIG. 9), which is perpendicular to the first direction and / or the second direction. That is, the extension direction of the third axis of the water inlet chamber is perpendicular to the extension direction of the first axis 001 of the cleaning pump housing 10 and / or the extension direction of the second axis 002 of the drain pump housing 20.

[0089] In this way, the size of the water inlet chamber can be reduced in the axial direction of the first axis 001 and the second axis 002, which helps to reduce the space occupied in the axial direction of the first axis 001 and the second axis 002, thereby helping to reduce the space occupied by the baby bottle washing machine.

[0090] For example, the third direction is perpendicular to the first and second directions. It can be understood that the first, second, and third directions can be three directions in a spatial coordinate system.

[0091] In one embodiment, the water inlet hole 302 of the water inlet chamber 301 is connected to the cleaning chamber inside the machine body, and the washing water in the cleaning chamber can enter the water inlet chamber 301 through the water inlet hole 302. During the washing process, the washing water in the cleaning chamber enters the water outlet chamber 101 from the water inlet chamber 301, and then enters the cleaning chamber through the water outlet hole 102. The washing water in the cleaning chamber circulates between the cleaning chamber, the water inlet chamber 301, and the water outlet chamber 101. During the draining process after washing, the washing water in the cleaning chamber enters the drain chamber 201 from the water inlet chamber 301, and then is discharged to the outside through the drain hole 202.

[0092] In one embodiment, the body includes a circulation inlet and a circulation outlet communicating with the cleaning chamber. The circulation inlet is communicating with the water outlet 102 of the water outlet chamber 101, and the circulation outlet is communicating with the water inlet 302 of the water inlet chamber 301.

[0093] In one embodiment, to facilitate the manufacture of the baby bottle cleaning machine, the water inlet shell 30, the cleaning pump shell 10, and the drain pump shell 20 are integrally connected.

[0094] The inventors discovered that during the cleaning process of the washing machine, impurities removed from the items being cleaned mix with the washing water. During the cleaning process, the washing water circulates between the cleaning chamber, the inlet chamber 301, and the outlet chamber 101. Large impurities in the washing water entering the outlet chamber 101 of the cleaning pump housing 10 may cause the cleaning pump to become clogged. Furthermore, during the draining process, some impurities in the washing water entering the drain chamber 201 of the drain pump housing 20 may cause the drain pump to become clogged.

[0095] Please refer to Figures 7, 10 and 11 together. The baby bottle cleaning machine provided in this application embodiment also includes a filter element, which is used to filter the washing water entering the water outlet chamber 101 and the sewage discharge chamber 201.

[0096] The filter element can be installed at the circulation outlet of the cleaning chamber.

[0097] In one embodiment, at least a portion of the filter element is disposed within the water inlet cavity 301 through the water inlet hole 302. The filter element includes a filter channel and a water inlet communicating with the filter channel, a first filter screen and a second filter screen. The first filter screen includes a plurality of first filter holes, and the second filter screen includes a plurality of second filter holes.

[0098] The first filter screen is connected to the water outlet chamber 101, and the second filter screen is connected to the sewage discharge chamber 201. The diameter of the first filter hole is smaller than the diameter of the second filter hole.

[0099] In this way, the bottle washing machine provided by this application can use the first filter screen of the filter element to filter the washing water entering the outlet chamber 101 of the washing pump, thus preventing clogging of the washing pump. The bottle washing machine provided by this application can also use the second filter screen of the filter element to filter the washing water entering the drain chamber 201 of the drain pump, thus preventing clogging of the drain pump.

[0100] In addition, the first filter screen has a smaller pore size, which can prevent impurities from entering the water outlet chamber 101, while the second filter screen has a larger pore size, which can allow some impurities to be discharged from the drain pump along with the washing water.

[0101] In one embodiment, the filter element includes a filter tube, the cavity of which includes a filter channel. A first filter screen and a second filter screen are disposed on the tube wall of the filter tube, and a communication port is also disposed in the filter tube. This facilitates the fabrication of the first and second filter screens.

[0102] The first and second filters can be integrated into the filter tube.

[0103] In one embodiment, the filter element further includes a mounting component connected to the filter tube, and the filter element can be mounted at the bottom of the cleaning chamber via the mounting component.

[0104] The mounting component has a water collection tank, and the water inlet is connected to the water collection tank. The water collection tank can guide the washing water to the filter channel, which helps to improve the filtration efficiency.

[0105] In some embodiments, the baby bottle cleaning machine provided in this application also includes a drain valve (not shown in the figure), which is disposed at the drain hole 202 and is used to open or close the drain hole 202.

[0106] The drain valve can remain closed during the washing process to prevent wash water from leaking out through the drain chamber 201 and drain hole 202. Alternatively, the drain valve can be opened during the draining process, allowing used wash water to be discharged to the outside through the drain chamber 201 and drain hole 202.

[0107] In one embodiment, the drain valve can be a solenoid valve.

[0108] Please refer to Figures 8 and 12 together. In some embodiments, the inlet shell 30 has a first connecting hole 303 communicating with the outlet chamber 101 and a second connecting hole 304 communicating with the drain chamber 201. The first axis 001 coincides with the central axis of the first connecting hole 303, and the second axis 002 coincides with the central axis of the second connecting hole 304.
