Background Art

[0002] At present, with the increase of the use time of the known fully automatic pulsator washing machine, a large amount of dirt and harmful bacteria will accumulate on the surface of the inner and outer barrels of the washing machine, which is difficult for non-professionals to remove. Although some fully automatic pulsator washing machines are currently equipped with a self-cleaning function, the self-cleaning program must be started separately, which is energy-consuming, water-consuming and time-consuming. The key is that the self-cleaning function is easily ignored, the utilization rate of the self-cleaning function is low, and the cleaning effect is not thorough. When washing clothes again, the dirt and harmful bacteria on the surface of the inner and outer barrels will cause secondary pollution to the clothes, which is very harmful to people's health. Summary of the invention

Pin 1 of the starting coil of relay J2 is connected to pin 3 of IC2, and pin 2 is connected to the negative pole of the power supply. One end of the switches J2-1 and J2-2 of relay J2 are respectively connected to the positive pin 3 and negative pin 2 of the power output terminal of the 8V three-terminal voltage regulator integrated circuit IC1 7808. The other ends of the switches J2-1 and J2-2 of relay J2 are respectively connected to the power supply of the second-stage delay circuit composed of C4, R2, C5, time base integrated circuit IC3NE555, and relay J3. Pin 1 of the starting coil of relay J3 is connected to pin 3 of IC3NE555, and pin 2 is connected to the positive pole of the power supply. One end of the switches J3-1 and J3-2 of relay J3 are respectively connected to the AC 220V power supply of the washing machine. The other ends of the switches J3-1 and J3-2 of relay J3 are respectively connected to the two ends of the starting coil of the water inlet solenoid valve.An independent self-cleaning water supply solenoid valve is arranged in the structure of the washing machine, one end of the water supply solenoid valve water inlet pipe is connected to the water supply solenoid valve water inlet, the other end of the water supply solenoid valve water inlet pipe is connected to the washing machine water supply pipeline, the water supply solenoid valve adopts a single water inlet and double water outlet model, one water outlet of the water supply solenoid valve is connected to the washing tub water supply pipe, the other water outlet of the water supply solenoid valve is connected to one end of the water supply solenoid valve water outlet pipe, the other end of the water supply solenoid valve water outlet pipe is connected to one end of the self-cleaning water inlet pipe, and the other end of the self-cleaning water inlet pipe is connected to three groups of self-cleaning water supply pipes arranged in the outer barrel structure of the washing machine. A plurality of self-cleaning water supply branch pipes are connected through the structure of the three groups of self-cleaning water supply pipes, and each self-cleaning water supply branch pipe is connected to a water spray head. A self-cleaning water inlet pipe, three groups of self-cleaning water supply pipes, multiple self-cleaning water supply branch pipes, and multiple water spray heads are arranged in the outer barrel structure of the washing machine. The self-cleaning water inlet pipe, three groups of self-cleaning water supply pipes, multiple self-cleaning water supply branch pipes, and multiple water spray heads are interconnected to form a self-cleaning spray device for the washing machine. The positions of the three groups of self-cleaning water supply pipes are as follows: a self-cleaning water supply pipe 12 is installed around the outer barrel of the washing machine, a self-cleaning water supply pipe 13 is installed in the vertical direction of the outer barrel of the washing machine, the upper end is interconnected with the self-cleaning water supply pipe 12, and the lower end reaches the bottom of the outer barrel of the washing machine. A self-cleaning water supply pipe 14 is installed at the bottom of the outer barrel of the washing machine, and the self-cleaning water supply pipe 14 is interconnected with the self-cleaning water supply pipe 13. After the washing machine enters the dehydration program, the power supply of the washing machine drainage motor is used to start the self-cleaning control circuit. After the starting coil of the relay J1 in the self-cleaning control circuit is energized, the switches J1-1 and J1-2 of the relay J1 are closed, and the 1st and 5th pins of the relay J1, the switch J1-1 of the relay J1 and the 2nd and 6th pins of the relay J1, the switch J1-2 of the relay J1 respectively transmit the 220V AC power supply of the washing machine to the two ends of the primary coil L1 of the 12V transformer B. The 12V transformer B converts the 220V AC power supply voltage of the washing machine into a 12V AC voltage, which is transmitted to the rectifier circuit composed of D1-D4 by the secondary coil L2. After rectification, a 12V DC voltage is obtained, and the residual AC component is filtered out by the capacitor C1 to obtain a pure 12V DC voltage, which is transmitted to the 1st pin of the three-terminal voltage regulator integrated circuit IC1 7808, and the 8V DC voltage is output from the 3rd pin of IC1 and transmitted to the timing integrated circuit IC2 The power input end of the first-stage delay circuit composed of NE555, C2, R1, C3, and relay J2, pin 1 of relay J2 is connected to pin 3 of the timing integrated circuit IC2 NE555, and pin 2 is connected to the negative pole. At this moment, pin 3 of the timing integrated circuit IC2 NE555 is at a low voltage, no current is generated in the starting coil of relay J2, and switches J2-1 and J2-2 of relay J2 are disconnected.At this time, R1 charges C2. As the charging time increases, when the voltages at pins 2 and 6 of the timing integrated circuit IC2 NE555 reach 2 / 3 of the power supply voltage, the voltage at pin 3 of the timing integrated circuit IC2 NE555 suddenly changes, and a potential difference is formed between pins 1 and 2 of the starting coil of relay J2, generating current in the starting coil of relay J2. At the same time, switches J2-1 and J2-2 of relay J2 are closed, and 8V DC voltage is transmitted to the second-stage delay circuit composed of C4, R2, C5, timing integrated circuit IC3 NE555, and relay J3. Pin 1 of the starting coil of relay J3 is connected to pin 3 of IC3, and pin 2 is connected to the positive electrode of 8V voltage. At this moment, the timing integrated circuit IC3 Pin 3 of NE555 is at low voltage, and pins 1 and 2 of the starting coil of relay J3 form a potential difference, generating current in the starting coil of relay J3. Switches J3-1 and J3-2 of relay J3 are closed, and the AC 220V power supply of the washing machine is transmitted to the starting coil of a separate water inlet solenoid valve. After the water inlet solenoid valve is started, the clean water in the water supply pipeline of the washing machine passes through the water inlet solenoid valve inlet pipe, the water inlet solenoid valve, and the water inlet solenoid valve outlet pipe to provide water flow to the washing machine self-cleaning spray device composed of a self-cleaning water inlet pipe, three sets of self-cleaning water supply pipes, multiple self-cleaning water supply branch pipes, and multiple water spray heads arranged in the outer barrel structure of the washing machine. The water flows through the water inlet solenoid valve inlet pipe, the water inlet solenoid valve, and the water inlet solenoid valve outlet pipe. The washing machine is equipped with a self-cleaning water inlet pipe, three sets of self-cleaning water supply pipes, multiple self-cleaning water supply branch pipes, and multiple water spray heads to spray the outer wall of the inner barrel of the washing machine. At this time, a water flow will be formed on the outer wall of the inner barrel of the washing machine to clean the residual dirt and harmful bacteria on the outer wall of the inner barrel of the washing machine. Since the inner barrel of the washing machine is in a high-speed rotating state at this time, according to the principle of centrifugal force, the water flow on the outer wall of the inner barrel of the washing machine will be reflected to the inner wall of the outer barrel of the washing machine, and a water flow will also be formed on the inner wall of the outer barrel of the washing machine, and the residual dirt and harmful bacteria on the inner wall of the outer barrel of the washing machine will be cleaned at the same time. Through the above process, the residual dirt and harmful bacteria in various parts of the inner and outer barrels of the washing machine are completely removed, and the residual dirt and harmful bacteria are discharged outside the washing machine through the drain pipe of the washing machine along with the water flow. As the charging time of C4 by R2 increases, when the voltage of pins 2 and 6 of the timing integrated circuit IC3 NE555 reaches 2 / 3 of the power supply voltage, the voltage of pin 3 of the timing integrated circuit IC3 NE555 suddenly changes, and there is no potential difference between pins 1 and 2 of the starting coil of relay J3. The starting coil of relay J3 loses current, and switches J3-1 and J3-2 of relay J3 are disconnected, cutting off the AC 220V power supply of the starting coil of the water inlet solenoid valve. The water inlet solenoid valve immediately closes the water flow and stops supplying water to the washing machine self-cleaning spray device composed of a self-cleaning water inlet pipe, three sets of self-cleaning water supply pipes, multiple self-cleaning water supply branch pipes, and multiple water spray heads arranged in the outer barrel structure of the washing machine, thereby automatically achieving the purpose of self-cleaning of the washing machine.After the washing machine enters the dehydration program, the starting power supply of the washing machine drainage motor is used to start the washing machine self-cleaning control circuit. The washing machine self-cleaning control circuit starts an independent water supply solenoid valve to provide water flow to the self-cleaning spray device in the outer barrel structure of the washing machine, so as to clean the residual dirt and harmful bacteria in various parts of the inner barrel and outer barrel interlayer of the washing machine, and ensure the internal cleanliness of the washing machine. Since the structure of the existing fully automatic pulsator washing machine is well known in the washing machine technology industry, in order to make the abstract, specification, specification drawings, and claims more concise, the present invention only describes and identifies the components related to the present invention in the existing fully automatic pulsator washing machine structure in the abstract, specification, specification drawings, and claims. A fully automatic self-cleaning pulsator washing machine is a fully automatic pulsator washing machine structure that adds a set of washing machine self-cleaning control system composed of a washing machine self-cleaning control circuit, a self-cleaning water supply solenoid valve, a self-cleaning water inlet pipe, a self-cleaning water supply pipe, a self-cleaning water supply branch pipe, and a water spray head. The fully automatic pulsator washing machine self-cleaning control system consists of two parts: 1. washing machine self-cleaning control circuit; 2. washing machine self-cleaning spray device.

[0006] 1. Washing machine self-cleaning control circuit: A washing machine self-cleaning control circuit and a self-cleaning water supply solenoid valve are added to the program control circuit of the existing fully automatic pulsator washing machine.

[0007] 2. Washing machine self-cleaning spray device: A self-cleaning water inlet pipe, three sets of self-cleaning water supply pipes, multiple self-cleaning water supply branch pipes, and multiple water spray heads are arranged at different positions on the outer barrel structure of the existing fully automatic pulsator washing machine. The self-cleaning water inlet pipe, the self-cleaning water supply pipe, and the self-cleaning water supply branch pipe are arranged on the outer wall of the outer barrel of the washing machine, and the water spray head is arranged on the inner wall of the outer barrel of the washing machine. One end of the self-cleaning water inlet pipe is respectively connected to the three sets of self-cleaning water supply pipes, and the three sets of self-cleaning water supply pipes, the multiple self-cleaning water supply branch pipes, and the multiple water spray heads are interconnected to form a washing machine self-cleaning spray device.

[0008] After the program control circuit of the fully automatic pulsator washing machine enters the dehydration program, the drainage motor or drainage pump of the washing machine is started to discharge the washing sewage. At the same time, the starting power of the drainage motor or drainage pump of the washing machine starts the self-cleaning control circuit of the washing machine. The self-cleaning control circuit of the washing machine starts the self-cleaning water supply solenoid valve within a certain period of time. After the self-cleaning water supply solenoid valve is started, water flows through the washing machine water inlet pipe, the self-cleaning water supply solenoid valve, the self-cleaning water inlet pipe, the self-cleaning water supply pipe, the self-cleaning water supply branch pipe, and the water spray head to spray water to multiple parts of the inner and outer walls of the inner and outer walls of the washing machine, so that various parts of the inner and outer walls of the washing machine are The residual dirt and harmful bacteria on various parts of the inner wall of the outer barrel of the washing machine are also cleaned by the water flow, and the residual dirt and harmful bacteria on various parts of the interlayer between the inner barrel and the outer barrel of the washing machine are automatically cleaned, and the residual dirt and harmful bacteria are discharged out of the washing machine through the drain pipe of the washing machine along with the water flow.

[0009] The water supply solenoid valve adopts a single water inlet and double water outlet model. The two water outlets of the water supply solenoid valve supply water to the washing machine washing tub and the washing machine self-cleaning spray device respectively. The water outlet of the self-cleaning water supply solenoid valve is connected with the self-cleaning water inlet pipe.

[0010] The beneficial effect of the present invention is that when the fully automatic self-cleaning pulsator washing machine enters the dehydration program, there is no need to separately turn on the self-cleaning function of the washing machine. Only a small amount of water is needed to automatically and thoroughly remove the residual dirt and harmful bacteria in various parts of the inner barrel and the outer barrel interlayer of the washing machine, thereby achieving the purpose of self-cleaning of the fully automatic pulsator washing machine, and completely changing the current situation of "wastewater washing and secondary pollution of clothes" of the existing fully automatic pulsator washing machine, providing a guarantee for people's health.

DETAILED DESCRIPTION

[0021] Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6In the embodiment of the present invention, after the fully automatic self-cleaning pulsator washing machine program control circuit 24 enters the dehydration program, power is supplied to the 1st and 2nd feet of the washing machine's drainage motor or drainage pump 21 and the 3rd and 4th feet of the coil of the relay J1 through the A and B lines at the same time, and the washing machine's drainage motor or drainage pump 21 starts to discharge the washing sewage. At the same time, current is generated at both ends of the coil 3rd and 4th feet of the relay J1. At this time, J1-1 and J1-2 are closed, and the 220V voltage of the 1st and 2nd feet of the relay J1 is transmitted to the primary coil L1 of the 12V transformer B through the 5th and 6th feet. The 220V AC voltage is converted into a 12V AC voltage by the 12V transformer B, and is transmitted to the rectifier circuit composed of D1-D4 by the secondary coil L2. After rectification, a 12V DC voltage is obtained, and the residual AC component is filtered out by the capacitor C1 to obtain a pure 12V DC voltage, which is transmitted to the 1st foot of the three-terminal voltage regulator integrated circuit IC1 7808, and the 8V DC voltage is output from the 3rd foot of IC1 and transmitted to the rectifier circuit composed of IC2 The first-stage delay circuit consists of NE555, C2, R1, C3, and relay J2. Pin 1 of relay J2 is connected to pin 3 of IC2, and pin 2 of J2 is connected to the negative pole of the power supply. At this time, pin 3 of IC2 is at low voltage, and pins 1 and 2 of J2 coil do not generate current. J2-1 and J2-2 are disconnected. At this time, R1 charges C2. As the charging time increases, when the voltage of pins 2 and 6 of IC2 reaches 2 / 3 of the power supply voltage, the voltage of pin 3 of IC2 suddenly changes, and the coil of relay J2 generates current. At the same time, J2-1 and J2-2 are closed, and the 8V voltage is transmitted to C4, R2, C5, and IC3. The second-stage delay circuit is composed of NE555 and relay J3. Pin 1 of relay J3 is connected to pin 3 of IC3, and pin 2 is connected to the positive pole of 8V voltage. At this time, pin 3 of IC3 is at low voltage, and a potential difference is formed at both ends of pins 1 and 2 of the coil of relay J3 to generate current. J3-1 and J3-2 are closed, and the 220V AC voltage is transmitted to the C and D pins of the starting coil of the self-cleaning water supply solenoid valve 18.2. After the self-cleaning water supply solenoid valve 18.2 is started, water flows through the water supply solenoid valve inlet pipe 19, the self-cleaning water supply solenoid valve 18.2, the self-cleaning water supply solenoid valve outlet pipe 17, and supplies water to the self-cleaning water inlet pipe 16 of the self-cleaning spray device. The water inlet pipe 16 supplies water to the self-cleaning water supply pipes 12, 13, and 14 respectively at the same time, and the water flows through multiple self-cleaning water supply branch pipes 22 to supply water to multiple water spray heads 15 respectively, and the multiple water spray heads 15 then spray water to the corresponding parts of the outer wall 9 of the inner barrel of the washing machine respectively, so as to thoroughly clean the residual dirt and harmful bacteria in the corresponding parts of the outer wall 9 of the inner barrel of the washing machine. At this time, since the inner barrel 2 of the washing machine is in a high-speed rotation state, a water flow will be formed on the surface of the inner and outer barrel interlayer 11 of the washing machine, and the water flow will thoroughly clean the residual dirt and harmful bacteria in the inner and outer barrel interlayer 11 of the washing machine, and the residual dirt and harmful bacteria will be discharged outside the washing machine through the drain pipe of the washing machine along with the water flow.As the charging time of C4 by R2 increases, when the voltage of pins 2 and 6 of IC3 reaches 2 / 3 of the power supply voltage, the voltage of pin 3 of IC3 suddenly changes, there is no potential difference between the two ends of pins 1 and 2 of the coil of relay J3 and the current is lost, J3-1 and J3-2 are disconnected, and pins 1 and 2 of the self-cleaning water supply solenoid valve 18.2 lose current and the water flow is immediately shut down, stopping the water supply to the self-cleaning spray device of the washing machine, and the self-cleaning process of the washing machine ends.

[0022] Figure 1 , Figure 3 , Figure 4 In the embodiment of the present invention, after the program control circuit 24 of the fully automatic pulsator washing machine enters the dehydration program, power is provided to the drainage motor or drainage pump 21 and the self-cleaning control circuit 20 of the washing machine at the same time. The self-cleaning control circuit 20 starts the self-cleaning water supply solenoid valve 18.2 within a certain period of time, and the water flows through the water supply solenoid valve inlet pipe 19, the self-cleaning water supply solenoid valve 18.2, and the self-cleaning water supply solenoid valve outlet pipe 17 to supply water to the self-cleaning spray device of the washing machine. By changing the resistance of R1 and the capacity of C2, the time when the self-cleaning water supply solenoid valve 18.2 starts supplying water to the self-cleaning spray device of the washing machine can be set. By changing the resistance of R2 and the capacity of C4, the time when the self-cleaning water supply solenoid valve 18.2 stops supplying water to the self-cleaning spray device of the washing machine can be set.

The number of water spray heads 15 is determined by the circumference of the inner wall 8 of the outer barrel of the washing machine. The outer wall 9 of the inner barrel of the washing machine should be fully contacted with the water sprayed by the plurality of water spray heads 15 around the corresponding horizontal direction. The plurality of water spray heads 15 are in the same plane with the inner wall 8 of the outer barrel of the washing machine and there should be no concave or convex surfaces.

The number of water spray heads 15 is determined by the vertical height of the inner wall 8 of the outer barrel of the washing machine. The corresponding parts of the outer wall 9 of the inner barrel of the washing machine should be fully in contact with the water sprayed by the plurality of water spray heads 15. The plurality of water spray heads 15 are in the same plane with the inner wall 8 of the outer barrel of the washing machine and there should be no concave or convex surfaces.

The washing machine self-cleaning spray device can be formed by a single-piece assembly method or by one-time injection molding, but the plurality of water spray heads 15 and the plurality of self-cleaning water supply branch pipes 22 are connected by screw ports for easy maintenance.

[0029] Figure 1 , Figure 3 , Figure 5 , Figure 6In the process, multiple water spray heads 15 spray water toward the outer wall 9 of the inner barrel of the washing machine. The purpose is to make the outer wall 9 of the inner barrel of the washing machine fully contact with the water flow during the self-cleaning process. While the inner barrel 2 of the washing machine rotates at a high speed, the inner and outer barrel interlayers 11 of the washing machine are fully contacted with the water flow, and the residual dirt and harmful bacteria on the surface of the inner and outer barrel interlayers 11 of the fully automatic pulsator washing machine are completely removed, thereby achieving the purpose of self-cleaning of the fully automatic pulsator washing machine.
