On the left and right sides of the washing tub are respectively provided forward-rotating vortex water jet connectors, which are fixedly and sealed to the lower and middle pipe walls of the washing tub and interconnected within the pipes. Inside the forward-rotating vortex water jet connectors are forward-rotating oblique water jets that, after water is introduced, tangentially spray water and generate rotating vortex water within the washing tub. The front and rear sides of the washing tub are respectively provided with… A reverse vortex spray connector has pipes at the same height as the forward vortex spray connector, which are fixedly and sealed to the lower and middle pipe walls of the washing tub and communicate with each other inside the tub. Inside the reverse vortex spray connector are reverse oblique spray nozzles that, after water is passed through, tangentially spray water in the opposite direction to the forward oblique spray nozzles and create a vortex of water rotating in the opposite direction within the washing tub. On the lower side of the washing tub, there is a wastewater collection box with a circular pipe that is fixedly and sealed to the lower center of the washing tub and communicates with each other inside the tub. A filter screen box is movably placed inside the upper port of the sealed lower section of the wastewater collection box. On the left and right sides of the wastewater collection box are pipes that are fixedly and sealed to the pipe walls of the wastewater collection box. The system includes a water inlet pipe and a lower hot air inlet pipe connected to each other in a circular pipe. A low water level sensor inlet pipe is located on the front side of the wastewater collection box, fixedly and sealed to the wall of the wastewater collection box and connected internally. Its height is lower than that of the lower hot air inlet pipe. A low water level sensor, connected to the washing machine's main control board, is installed inside this low water level sensor inlet pipe and fixedly and sealed to it. A drain inlet pipe is located on the lower side of the wastewater collection box, fixedly and sealed to the bottom of the wastewater collection box and connected internally. A drain inlet pipe is located at the middle of the washing tub, fixedly and sealed to the wall of the middle section of the washing tub and connected internally. Its height is higher than that of the lower hot air inlet pipe. The washing machine features a high-water-level sensor connector, a circular tube with a forward-rotating vortex water jet connector. Inside this connector is a high-water-level sensor that is fixedly and sealed to the main control board of the washing machine. Above the high-water-level sensor connector is an upper hot air connector, a pipe for supplying hot air that is fixedly and sealed to the upper wall of the washing tub and communicates with the interior of the tub. To the left or right of this upper hot air connector is a washing connector, also fixedly and sealed to the upper wall of the washing tub and communicating with the interior of the tub. At the front, left, or right side of the washing tub is a bottle or small container for storing washing liquid, fixedly connected to the upper end of the washing tub via a bracket.A detergent pump, controlled by the washing machine's main control board, is installed between the detergent bottle and the washing connector. This pump, connected to both the detergent bottle and the washing connector via a thin flexible tube, draws detergent into the washing tub. A water inlet connector, located at the rear of the washing tub and connected to the upper wall of the tub, is a circular pipe with a height lower than the upper hot air connector. To the left or right of this water inlet connector, a pipe connected to both the water inlet connector and tap water is installed. This pipe, controlled by the washing machine's main control board, shuts off when the water level exceeds the height of the high water level sensor during the water intake process. The washing machine's main control board controls a water pump. At the left or right end of the front side of the washing tub, there is a water inlet port fixedly connected to the lower end of the tub via a bracket. This inlet port is sealed and connected to the water pumping interface pipe via a water trap. Above the water pump are a forward vortex solenoid valve and a reverse vortex solenoid valve, each controlled by the main control board and sealed and connected to the water pump's outlet port via a pipe. Above each of the forward and reverse vortex solenoid valves are either sealed and plugged into or screwed into each valve. The upper end of each five-way pipe is respectively connected to the forward vortex water jet connector and the reverse vortex water jet connector via pipes. At the right or left end of the front side of the washing tub, there is a drying bidirectional flow fan controlled by the washing machine's main control board. The lower end of the fan is fixedly connected to the upper end of the washing tub via a bracket and is connected to the lower hot air connector via a pipe. The fan stops when the water level is higher than the low water level sensor. Above the drying bidirectional flow fan, there is a pipe connecting the upper end of the fan to the hot air connector. The upper end of the hot air inlet pipe is sealed and connected to the main control board of the washing machine. It automatically reduces heating power or cuts off power when the water level exceeds the height of the low water level sensor. A drying heater stops when the water level exceeds the height of the low water level sensor. An annular stop ring is fixedly inserted into the upper port of the washing tub to prevent overflow of the swirling water sprayed inside the tub. At the lower rear end of the washing tub, a drain valve or a solenoid valve and water pump is connected to the drain interface pipe via a sealed connection. This drain valve is controlled by the main control board and automatically activates when the water level exceeds the height of the low water level sensor during the drying process.
[0005] The beneficial effects of this invention are as follows: When the washing machine enters the water pump start program, the water pump is energized to circulate water. Simultaneously, the forward and reverse vortex solenoid valves are alternately energized. When the forward vortex solenoid valve is energized, water passes through the forward-rotating angled spray nozzle, generating tangential water jets and rotating vortices within the washing tub. When the reverse vortex solenoid valve is energized, water passes through the reverse-rotating angled spray nozzle, generating water jets in the opposite direction to the forward-rotating angled spray nozzles and rotating vortices in the opposite direction within the washing tub. The water jets generated by the forward and reverse angled spray nozzles create relative friction between the water and the clothes, and friction also occurs due to the speed difference between the clothes and the rotating vortex. This results in rapid washing of the clothes. During the washing process, there is no friction, rotation, or transmission between any parts, resulting in low power consumption. When the washing machine enters the drying heater start program, the drying heater and the bidirectional drying fan are simultaneously energized, and the washing tub... The internal heating system generates hot air that passes over the clothes, drying them. The drying fan operates in both forward and reverse directions, allowing the clothes to be dried alternately by the hot air. When the washing machine enters the wash cycle, the drain valve is activated to drain water. Once the drying heater and drying fan start cycle begin, the drain valve is activated again when the water level exceeds the low water level sensor. During the drying process, there is no friction, rotation, or transmission between any components, resulting in minimal vibration and shaking. The washing tub, drainage trough, forward vortex spray nozzle, reverse vortex spray nozzle, wastewater collection box, water inlet pipe, lower hot air nozzle, low water level sensor inlet pipe, drain pipe, high water level sensor nozzle, upper hot air nozzle, washing nozzle, and water inlet nozzle are all injection molded in the same mold, making them leak-proof, easy to manufacture, and low-cost.

[0014] The working principle of this utility model is as follows:
[0015] A washing tub 1 is constructed using a circular tube with a fixed seal at the bottom, surrounded by a washing machine outer shell, a washing machine cover on the upper side, a fixed bracket on the lower side, and a main control board at the front of the upper port. The washing tub 1 is stationary and has no driving or transmission components. Multiple downward-facing, concave water channels 22, arranged radially at the bottom of the washing tub 1, facilitate water flow and drying of clothes. On the left and right sides of the washing tub 1 are respectively fixedly and sealed to the lower and middle pipe walls of the washing tub 1 and interconnected with each other. A forward-rotating vortex water jet connector 6 is provided within the forward-rotating vortex water jet connector 6, which, when water is introduced, tangentially sprays water and generates a rotating vortex within the washing tub 1. The washing tub 1 has a water head that generates tangential water jets and rotating vortex water. Reverse vortex water jet connectors 19 are located on the front and rear sides of the washing tub 1, respectively, and are fixedly and sealed to the lower and middle pipe walls of the washing tub 1, and are interconnected internally. The height of these connectors is the same as that of the forward vortex water jet connector 6. Inside the reverse vortex water jet connector 19, there are reverse oblique water jets that, when water is passed through, generate tangential water jets and rotating vortex water in the opposite direction to the forward oblique water jets within the washing tub 1. Water flow generates tangential water jets and rotating vortex water in the opposite direction to the forward oblique water jets. On the lower side of the washing tub 1, there is a fixedly and sealed connector to the lower center of the washing tub 1, and the internal pipes are interconnected. A wastewater collection box 14 is formed by a circular pipe containing a filter screen that is movably placed inside the sealed upper port of the wastewater collection box. This wastewater collection box 14 facilitates wastewater collection, and the filter screen filters out impurities. On the left and right sides of the wastewater collection box 14 are respectively a water inlet pipe 11 and a lower hot air inlet pipe 13, which are fixedly and sealed to the pipe wall of the wastewater collection box 14 and communicate with each other internally. The water inlet pipe 11 and the lower hot air inlet pipe 13 facilitate pipe connection or insertion. On the front side of the wastewater collection box 14 is a low water level sensor inlet pipe 15, which is fixedly and sealed to the pipe wall of the wastewater collection box 14 and communicates with each other internally. Its height is lower than that of the lower hot air inlet pipe 13. Inside the low water level sensor inlet pipe 15 is a... A low-water-level sensor, which is fixedly and sealed to the interface pipe 15 of the low-water-level sensor and connected to the main control board of the washing machine, enables the detection of low water levels. A drain interface pipe 12, a circular pipe with a fixed and sealed connection to the bottom of the wastewater collection box 14 and interconnected with the inside of the pipe, is provided on the lower side of the wastewater collection box 14, facilitating the connection or insertion of the drain pipe. A high-water-level sensor insertion pipe 5, a circular pipe with a height higher than the height of the forward-rotating vortex water jet insertion pipe 6, is provided at the middle of the washing tub 1, with a fixed and sealed connection to the middle pipe wall of the washing tub 1 and interconnected with the inside of the pipe. A high-water-level sensor, fixedly and sealed to the interface pipe 5 and connected to the main control board of the washing machine, enables the detection of high water levels.Above the high water level sensor connector 5, there is an upper hot air connector 16 for a hot air pipe that is fixedly and sealed to the upper wall of the washing tub 1 and communicates with the inside of the pipe. The upper hot air connector 16 is located at the upper end of the washing tub 1, and its height is higher than that of the high water level sensor, so water will not enter the pipe communicating with the upper hot air connector 16. To the left or right of the hot air connector 16, there is a washing connector 3 for a pipe that is fixedly and sealed to the upper wall of the washing tub 1 and communicates with the inside of the pipe. On the front, left, or right side of the washing tub 1, there is a washing liquid bottle 2 for storing washing liquid, which is fixedly connected to the upper end of the washing tub 1 by a bracket. A passage is provided between the washing liquid bottle 2 and the washing connector 3. A thin flexible tube is fixedly and sealed to the detergent bottle 2 and the washing connector 3, respectively. This tube is controlled by the washing machine's main control board and acts as a pump to draw detergent into the washing tub 1. When the washing machine enters the set detergent pump start program, the detergent pump is powered on and draws detergent into the washing tub 1 to remove stains from clothes. At the rear of the washing tub 1, there is a round pipe inlet connector 20, which is fixedly and sealed to the upper wall of the washing tub 1 and communicates with the interior of the pipe. Its height is lower than that of the upper hot air connector 16. To the left or right of the inlet connector 20, there is a pipe connected to the inlet connector 20 and tap water, respectively. This pipe is controlled by the washing machine's main control board and its water level exceeds the height of the inlet connector 3 during the water intake program. The washing machine's inlet valve, which closes the water supply via a solenoid valve when the water level exceeds the height of the high water level sensor, is connected to the washing machine's main control board. When the water level exceeds the height of the high water level sensor, the main control board controls the inlet valve to close the water supply. A water pump 10, controlled by the main control board, is located at the left or right end of the front side of the washing tub 1. This pump has an inlet port fixedly connected to the lower end of the tub 1 via a bracket and is sealed and connected to the water pumping interface pipe 11 via a water trap. Above the water pump 10 are a forward vortex solenoid valve 8 and a reverse vortex solenoid valve 9, each controlled by the main control board and sealed and connected to the outlet port of the pump 10 via a pipe. On the upper side of the forward vortex solenoid valve 8 and the reverse vortex solenoid valve 9, there are respectively a forward vortex five-way pipe 7 and a reverse vortex five-way pipe 4, whose lower ends are respectively sealed and plugged into or screwed into the forward vortex spray water connector 6 and the reverse vortex spray water connector 19 through pipes. When the washing machine enters the set water pump 10 start program, the water pump 10 is energized to circulate water. At the same time, the forward vortex solenoid valve 8 and the reverse vortex solenoid valve 9 are alternately energized. When the forward vortex solenoid valve 8 is energized, water passes through the forward vortex spray head, generating tangential water jets and rotating vortex water in the washing tub 1. When the reverse vortex solenoid valve 9 is energized, ...Water passes through the reverse angled spray nozzles, generating water jets in the opposite direction to those from the forward-rotating angled spray nozzles and vortex water rotating in the opposite direction within the washing tub 1. The water jets from both the forward and reverse angled spray nozzles create relative friction with the clothes, and the clothes also experience friction due to the speed difference between the clothes and the rotating vortex. This results in rapid washing of the clothes. At the front right or left end of the washing tub 1, there is a lower port fixedly connected to the upper end of the washing tub 1 via a bracket. This port is connected to the lower hot air inlet pipe 13 via a sealed connection, and is controlled by the washing machine's main control board. A drying bidirectional flow fan 18 stops when the water level in both the exhaust and reverse exhaust directions is higher than the low water level sensor. Above the drying bidirectional flow fan 18 is a drying heater 17, controlled by the washing machine's main control board. The heater's lower end is sealed and connected to the inside of the drying bidirectional flow fan 18 pipe, while its upper end is sealed and connected to the upper hot air inlet pipe 16 via a pipe. The heater automatically reduces heating power or cuts off power when the water level is higher than the low water level sensor. When the washing machine enters the set drying heater 17 start-up program... The drying heater 17 and the drying bidirectional flow fan 18 are powered on simultaneously. Hot air is generated inside the washing tub 1 and passes through the clothes, drying them. The drying bidirectional flow fan 18 can draw air in both forward and reverse directions, allowing the clothes to be dried by alternating passages of hot air. A ring-shaped water-stop ring 23 is fixedly inserted into the upper port of the washing tub 1 to prevent the overflow of the swirling water sprayed inside. The water-stop ring 23 prevents the sprayed, rotating swirling water from overflowing as it travels along the inner wall of the washing tub 1 towards the upper port. The washing tub 1 has a drain valve 21 located at its lower rear end, which is sealed and connected to the drain interface pipe 12 via a pipe. This drain valve is controlled by the main control board of the washing machine and automatically activates when the water level exceeds the height of the low water level sensor during the drying cycle. When the washing machine enters the set washing and water-changing program, the drain valve 21 is energized to drain water. After the washing machine enters the set program for starting the drying heater 17 and the drying bidirectional flow fan 18, the drain valve 21 is energized to drain water when the water level exceeds the height of the low water level sensor.

On the upper side of the water pump (10), there are respectively a forward vortex solenoid valve (8) and a reverse vortex solenoid valve (9) that are respectively connected to the water outlet port of the water pump (10) through pipes and are controlled by the main control board of the washing machine. On the upper side of the forward vortex solenoid valve (8) and the reverse vortex solenoid valve (9), there are respectively a forward vortex five-way pipe (7) and a reverse vortex five-way pipe (4) whose lower ends are respectively connected to the forward vortex solenoid valve (8) and the reverse vortex solenoid valve (9) through pipes and are respectively connected to the forward vortex spray water connector (6) and the reverse vortex spray water connector (19). On the right or left side of the front of the washing tub (1), there are two such pipes. The washing machine's main control board has a drying bidirectional flow fan (18) with its lower end fixedly connected to the upper end of the washing tub (1) via a bracket. This fan is sealed and connected to the lower end hot air connector (13) via a pipe. It can control the main control board to draw air in both directions and stop when the water level is higher than the height of the low water level sensor. Above the drying bidirectional flow fan (18) is a drying heater (17) with its lower end sealed and connected to the pipe of the drying bidirectional flow fan (18) and its upper end sealed and connected to the upper end hot air connector (16) via a pipe. This heater is controlled by the main control board to automatically reduce heating power or cut off power when the water level is higher than the height of the low water level sensor.A ring-shaped water-stop ring (23) is provided inside the upper end of the washing tub (1) and is fixedly inserted into the upper port of the washing tub (1) to prevent the overflow of the swirling water sprayed and agitated inside the washing tub (1). At the lower rear end of the washing tub (1), a drain valve (21) is provided, which is connected to the drain interface pipe (12) via a pipe and is controlled by the main control board of the washing machine. This drain valve is automatically activated when the water level is higher than the height of the low water level sensor during the drying process.
