Description

Technical Field

[0001] This invention belongs to the field of cleaning machine technology, and particularly relates to a compact cleaning machine. Background Technology

[0002] A cleaning machine is a device that sprays clean water from a clean water tank onto the surface of an object to be cleaned. The clean water cleans the surface, and the wastewater generated during cleaning is collected in a wastewater tank.

[0003] US Patent (US16990171) discloses a pet grooming system and various related devices for grooming pets. The pet grooming system may include components specifically designed for pet grooming, or may adapt surface cleaning devices or tools typically used for cleaning floors and upholstery to replace pet grooming. The pet grooming system may include a hand tool coupled to a portable module via a conduit assembly, at least a portion of which may be in the form of a flexible hose. Multiple pet grooming attachments are provided, and the hand tool can simultaneously mount grooming combs and spray attachments to groom the pet.

[0004] Currently, cleaning machines with large water tanks mostly adopt a separate design for their clean water tank and wastewater tank. This not only makes the operation of the clean water tank and wastewater tank inconvenient, but also increases the overall size of the cleaning machine, making it cumbersome to use. In addition, the narrow flow channel design of the cleaning machine not only fails to provide enough space for water vapor separation, but also increases the noise during the operation of the cleaning machine. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of the separate design of the clean water tank and the wastewater tank of the large water tank cleaning machine, which leads to the narrow flow channel of the cleaning machine, resulting in a dispersed structure, heavy use, insufficient water vapor separation and high noise. Therefore, this invention proposes a cleaning machine with a compact layout.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a compact cleaning machine, comprising a tub, a base, a fan, a bend pipe, and a water pump. The tub is inserted into the base from above, the bend pipe is connected to the base, the air duct on the bend pipe is connected to the tub, the water pump is connected to the tub and the water duct on the bend pipe respectively, and the fan is installed in a motor compartment inside the base, the motor compartment being connected to the tub.

The barrel lid is snapped onto the barrel body.

[0011] As a further description of the above technical solution:

[0012] The wastewater tank is equipped with a first pipe and a second pipe. The first pipe is connected to the air duct, and the second pipe is connected to the motor compartment. A guide is provided at the top of the first pipe. A filter HEPA filter is provided in the wastewater tank. The first pipe is located below the filter HEPA filter, and the upper end of the second pipe is connected to the top of the filter HEPA filter.

[0013] As a further description of the above technical solution:

[0014] The base includes a body, a base plate, a motor cover, and a bottom cover. The fan is mounted on the base plate, the motor cover is snapped onto the base plate and covers the fan, and the motor compartment is located inside the motor cover. The body is snapped onto the base plate from above, and the bottom cover is snapped onto the base plate from below. The motor cooling duct includes a first airflow compartment, a second airflow compartment, and a third airflow compartment. The first airflow compartment is formed between the body, the base plate, and the motor cover; the second airflow compartment is formed between the base plate and the bottom cover; and the third airflow compartment is formed between the base plate, the bottom cover, and the motor cover. The second airflow compartment is located around the third airflow compartment and below the first airflow compartment. The first airflow compartment connects the motor compartment and the second airflow compartment and is connected to the outside of the base. The second airflow compartment is connected to the outside of the base, and the third airflow compartment is connected to the motor compartment and the outside of the base.

[0015] As a further description of the above technical solution:

[0016] The motor cover is provided with a first outlet, which is connected to the first airflow chamber. The motor cover is provided with a plurality of second outlets around its perimeter, which are connected to the third airflow chamber.

[0017] As a further description of the above technical solution:

[0018] The body has multiple mesh openings that connect to the first airflow chamber. The top surface of the base plate has a first notch and a second notch. The first notch connects the first airflow chamber and the second airflow chamber. The second notch is located inside the third airflow chamber. The side of the bottom cover has a third notch and a fourth notch. The second airflow chamber is connected to the outside of the base through the third notch, and the third airflow chamber is connected to the outside of the base through the fourth notch.

[0019] As a further description of the above technical solution:

[0020] A third pipe is provided inside the machine body, and a flow guide chamber is formed between the bottom plate, the bottom cover and the motor cover. The third pipe connects the flow guide chamber and the barrel body. An air inlet is opened at the bottom of the motor cover, and the air inlet connects the flow guide chamber and the motor cover.

[0021] As a further description of the above technical solution:

[0022] The bottom of the barrel is provided with a water outlet, and a water outlet valve is provided on the water outlet.

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0024] 1. In this invention, the integrated design of the barrel body allows the clean water tank and the wastewater tank to be integrated into the barrel body, forming a vertical arrangement between the barrel body and the base. The water pump draws out the clean water from the clean water tank and sprays it out through the water channel on the bend pipe. The wastewater after cleaning enters the wastewater tank through the air duct on the bend pipe for water vapor separation. This achieves a compact overall structure and simplified layout, making it easy to use and lightweight, and providing a good user experience.

[0025] 2. In this invention, water vapor is introduced into the sewage tank through the first pipe. The guide component directs the water vapor downward, causing water to settle at the bottom of the sewage tank. After the airflow moves within the sewage tank, it passes through the filter HEPA filter and enters the space above the filter HEPA filter, becoming dry airflow. The dry airflow enters the guide chamber through the second and third pipes, providing the water vapor with a sufficiently large separation space and a sufficiently long separation path, thereby ensuring high water vapor separation efficiency and good water vapor separation effect.

[0026] 3. In this invention, the negative pressure generated by the fan draws dry airflow into the motor compartment through the air inlet. The airflow is split within the motor compartment, with one part entering the first airflow chamber from the first outlet and the other part entering the second airflow chamber from the second outlet. The airflow entering the first airflow chamber is partially released through the mesh, while most of the airflow swirls and is buffered within the first airflow chamber before entering the third airflow chamber through the first notch. The airflow swirls and is buffered within the third airflow chamber before finally exiting the base through the third notch. The airflow entering the second airflow chamber swirls and is buffered before finally exiting the base through the fourth notch. This achieves an ultra-long airflow buffering path, fully utilizes the space layout, and greatly reduces the noise generated by the airflow. Attached Figure Description

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figure 1-11 The present invention provides a technical solution: a compact cleaning machine, including a tub 1, a base 2, a fan 3, a bend 4, and a water pump 5. The tub 1 is inserted into the base 2 from above. The bend 4 is connected to the base 2. The air duct 6 on the bend 4 is connected to the tub 1. The water pump 5 is connected to the tub 1 and the water duct 7 on the bend 4 respectively. The fan 3 is installed in the motor compartment 8 inside the base 2. The motor compartment 8 is connected to the tub 1.

[0042] The base 2 is provided with a motor cooling duct 9, which is connected to the motor compartment 8 and is also connected to the outside.

[0043] The barrel body 1 includes a barrel body 11 and a barrel lid 12. The barrel body 11 is provided with a clean water tank 10 and a wastewater tank 13. The barrel body 11 is integrally formed. The wastewater tank 13 surrounds the clean water tank 10. The water pump 5 is connected to the clean water tank 10. The air duct 6 on the bend pipe 4 is connected to the wastewater tank 13. The motor compartment 8 is connected to the wastewater tank 13. The barrel lid 12 is snapped onto the barrel body 11. The integral design of the barrel body integrates the clean water tank 10 and the wastewater tank 13 into the barrel body 1, so that the barrel body 1 and the base 2 are arranged vertically. The water pump 5 draws out the clean water in the clean water tank 10 and sprays it out through the water duct 7 on the bend pipe 4. The cleaned wastewater enters the wastewater tank 13 through the air duct 6 on the bend pipe 4 for water vapor separation. This achieves a compact and simplified overall structure, making it easy to use and lightweight, and providing a good user experience.

[0044] The wastewater tank 13 is equipped with a first pipe 14 and a second pipe 15. The first pipe 14 is connected to the air duct 6, and the second pipe 15 is connected to the motor compartment 8. A guide 16 is provided at the top of the first pipe 14. A filter HEPA filter 17 is provided in the wastewater tank 13. The first pipe 14 is located below the filter HEPA filter 17, and the upper end of the second pipe 15 is connected to the top of the filter HEPA filter 17. The first pipe 14 introduces water vapor entering the air duct 6 into the wastewater tank 13. The guide 16 guides the water vapor downward so that the water is deposited at the bottom of the wastewater tank 13. After the airflow moves in the wastewater tank 13, it is filtered by the filter HEPA filter 17 and enters the top of the filter HEPA filter 17, becoming a dry airflow. The dry airflow enters the guide chamber 33 from the second pipe 15 and the third pipe 32, so that the water vapor has a sufficiently large separation space and a sufficiently long separation path, thereby ensuring high water vapor separation efficiency and good water vapor separation effect.

[0045] The base 2 includes a body 21, a base plate 22, a motor cover 23, and a bottom cover 24. The fan 3 is mounted on the base plate 22. The motor cover 23 is snapped onto the base plate 22 and covers the fan 3. The motor compartment 8 is located inside the motor cover 23. The body 21 is snapped onto the base plate 22 from above, and the bottom cover 24 is snapped onto the base plate 22 from below. The motor cooling duct 9 includes a first airflow compartment 18, a second airflow compartment 19, and a third airflow compartment 20. The first airflow compartment 18 is formed between the body 21, the base plate 22, and the motor cover 23. A second airflow chamber 19 is formed between the base plate 22 and the bottom cover 24, and a third airflow chamber 20 is formed between the base plate 22, the bottom cover 24 and the motor cover 23. The second airflow chamber 19 is located around the third airflow chamber 20 and is located below the first airflow chamber 18. The first airflow chamber 18 connects the motor chamber 8 and the second airflow chamber 19, and the first airflow chamber 18 is connected to the outside of the base 2. The second airflow chamber 19 is connected to the outside of the base 2, and the third airflow chamber 20 is connected to the motor chamber 8 and the outside of the base 2.

[0046] The motor cover 23 is provided with a first outlet 25, which is connected to the first airflow chamber 18. The motor cover 23 is provided with a plurality of second outlets 26 around its perimeter, which are connected to the third airflow chamber 20.

[0047] The body 21 has multiple mesh holes 27, which are connected to the first airflow chamber 18. The top surface of the base plate 22 has a first notch 28 and a second notch 29. The first notch 28 is connected to the first airflow chamber 18 and the second airflow chamber 19. The second notch 29 is located inside the third airflow chamber 20. The side of the bottom cover 24 has a third notch 30 and a fourth notch 31. The second airflow chamber 19 is connected to the outside of the base 2 through the third notch 30, and the third airflow chamber 20 is connected to the outside of the base 2 through the fourth notch 31.

[0048] A third pipe 32 is provided inside the body 21. A flow guide chamber 33 is formed between the bottom plate 22, the bottom cover 24, and the motor cover 23. The third pipe 32 connects the flow guide chamber 33 and the barrel 1. An air inlet 34 is provided at the bottom of the motor cover 23, and the air inlet 34 connects the flow guide chamber 33 and the motor compartment 8.

[0049] The negative pressure generated by the fan 3 draws dry airflow into the motor chamber 8 through the air inlet 34. The airflow is split within the motor chamber 8, with one part entering the first airflow chamber 18 from the first outlet 25 and the other part entering the second airflow chamber 19 from the second outlet 26. The airflow entering the first airflow chamber 18 is partially released through the mesh 27, while most of the airflow swirls and is buffered within the first airflow chamber 18. Then, it enters the third airflow chamber 20 through the first notch 28. The airflow swirls and is buffered within the third airflow chamber 20, and finally, the airflow exits the base 2 through the third notch 30. After swirling and being buffered, the airflow entering the second airflow chamber 19 exits the base 2 through the fourth notch 31. This achieves an ultra-long airflow buffering path, making full use of the space layout and greatly reducing the noise generated by the airflow.

[0050] The bottom of the barrel 1 is provided with a water outlet 35, and a water outlet valve 36 is provided on the water outlet 35. When the water outlet valve 36 on the barrel 1 touches the base 2, the water outlet valve 36 is in the open state, so that the liquid in the barrel 1 can flow out from the water outlet 35.

[0051] Working principle: First, pull the tank 1 from the base 2, separating the tank 1 and the base 2. Add clean water to the clean water tank 10, and attach the lid 12 to the tank body 11. Then, insert the tank 1 back into the base 2. When the water outlet valve 36 on the tank 1 touches the base 2, the water outlet valve 36 is open, allowing the liquid in the tank 1 to flow out from the outlet 35. Second, during use, the water pump 5 draws clean water from the clean water tank 10 and sprays it out through the water channel 7 on the bend pipe 4. The negative pressure generated by the fan 3 acts on the air duct 6 and the first pipe 14. The first pipe 14 introduces the water vapor entering the air duct 6 into the wastewater tank 13. The guide component 16 guides the water vapor downward, causing the water to settle at the bottom of the wastewater tank 13. After the airflow moves within the wastewater tank 13, it passes through the filter HEPA filter 17 and enters the area above the filter HEPA filter 17, becoming dry airflow. The dry airflow flows out through the second pipe 15 and the third pipe... Pipe 32 enters the guide chamber 33, providing a sufficiently large separation space and a sufficiently long separation path for water vapor. Then, the negative pressure generated by the fan 3 draws the dry airflow from the inlet 34 into the motor chamber 8. Within the motor chamber 8, the airflow is split: part enters the first airflow chamber 18 from the first outlet 25, and the other part enters the second airflow chamber 19 from the second outlet 26. A portion of the airflow entering the first airflow chamber 18 is released through the mesh 27, while most of the airflow swirls and is buffered within it. Then, it enters the third airflow chamber 20 from the first notch 28, where it swirls and is buffered again. Finally, the airflow exits the base 2 from the third notch 30. The airflow entering the second airflow chamber 19 swirls and is buffered before exiting the base 2 from the fourth notch 31, achieving an ultra-long airflow buffering path (airflow direction as shown). Figure 11 (As indicated by the arrow in the image), finally, pull the bucket 1 off the base 2, open the bucket lid 12, remove the filter HEPA filter 17 from the sewage tank 13, and pour out the sewage in the sewage tank 13.

[0052] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
