For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] like Figures 1 to 12 As shown, the pulsator washing machine of the present invention comprises a control disc base 1, a washing tub 2 and a spray head 3.

[0053] The pulsator washing machine also includes a housing, a pulsator, a driving device, etc. The washing tub 2 may include an inner and outer tub, or may be a single tub. When the washing tub 2 includes an inner and outer tub, the pulsator is rotatably mounted in the inner tub; the inner tub is rotatably mounted in the outer tub, and a balancing assembly is also mounted on the inner tub; a barrel ring is mounted on the outer tub and is arranged at the center of the housing; the driving device is mounted on the bottom of the outer tub and is located in the housing; clothes are usually placed in the inner tub, and the outer tub is used to hold water.

[0054] The driving device generally includes a motor and a clutch, the motor and the clutch are driven by a belt, the clutch is provided with a pulsator shaft and a dehydration shaft, the dehydration shaft and the pulsator shaft are compositely installed together in a concentric structure, the pulsator shaft sequentially passes through the bottom of the outer barrel and the inner barrel to be connected to the pulsator, the dehydration shaft passes through the bottom of the outer barrel and is connected to the bottom of the inner barrel. A ratchet pawl is also installed on the clutch to control the rotation of the dehydration shaft.

[0055] The outer tub is suspended at the center of the box body through a plurality of suspension rods; the suspension rods can suspend and reduce vibration of the outer tub to ensure dynamic balance and stability during washing and dehydration.

[0056] When washing clothes, the pulsator rotates while the inner tub does not rotate; the pulsator is provided with water-repelling ribs, and the forward and reverse rotation of the pulsator can drive the water flow to form a vortex that sometimes rotates right and sometimes rotates left, driving the clothes to tumble and wash the clothes. When the clothes are dehydrated, the pulsator and the inner tub will rotate in the same direction, and the rotation speeds of the pulsator and the inner tub are also the same.

[0057] After washing once, the clothes need to be drained and dehydrated. During dehydration, the clothes are closely attached to the inner peripheral wall of the inner barrel under the action of centrifugal force. After dehydration, the clothes will still be closely attached to the inner peripheral wall of the inner barrel for a period of time.

[0058] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the washing tub 2 is arranged below the control disc seat 1 .

[0059] The spray head 3 is arranged on the control panel seat 1 and is located above the washing tub 2. The spray head 3 has a fan-shaped liquid outlet channel 311. The fan-shaped liquid outlet channel 311 is arranged to be inclined downward toward the inner wall of the washing tub 2. The fan-shaped liquid outlet channel 311 is toward the side of the inner wall of the washing tub 2 away from the spray head 3.

[0060] In the above scheme, the fan-shaped liquid outlet channel 311 is set to spray a fan-shaped water flow, the spraying range of the fan-shaped water flow is larger, the water flow is stronger, and the spraying effect is better; the fan-shaped liquid outlet channel 311 is inclined downward toward the inner wall of the washing tub 2 away from the spray head 3, so that the fan-shaped water flow can fall directly on the inner wall of the washing tub 2 with a large coverage area, and can effectively spray the clothes that are close to the inner wall of the washing tub 2, which can speed up the soaking of clothes and improve the rinsing effect.

[0061] Preferably, when the washing tub 2 includes an inner and outer tub, the fan-shaped liquid outlet channel 311 is arranged to be inclined downward toward the inner circumferential wall of the inner tub, and the fan-shaped liquid outlet channel 311 is toward the side of the inner circumferential wall of the inner tub away from the spray head 3, and the fan-shaped water flow is sprayed to the side of the inner circumferential wall of the inner tub away from the spray head 3.

[0062] Specifically, during rinsing, the washing tub 2 works while the spray head 3 sprays water, so that most of the inner circumference of the washing tub 2 can be sprayed, which can speed up the soaking of clothes closely attached to the inner circumference of the washing tub 2.

[0063] like Figure 1 , Figure 5 and Figure 7 As shown, the fan-shaped liquid outlet flow channel 311 is arranged to be inclined downward in a transverse direction, and the fan-shaped liquid outlet flow channel 311 is arranged to be circumferentially offset from the connection line between the installation position of the spray head 3 and the axis of the washing tub 2 .

[0064] Specifically, the fan-shaped liquid outlet channel 311 is arranged to be inclined downward in a transverse direction, and the sprayed fan-shaped water flow covers a larger area of ​​the inner wall of the washing tub 2, which can increase the spray range of the fan-shaped water flow, which is beneficial to improving the rinsing effect. The fan-shaped liquid outlet channel 311 is arranged to deviate from the connection line between the installation position of the spray head 3 and the axis of the washing tub 2 in the circumferential direction, and can avoid other components installed on the control panel seat 1.

[0065] The central angle of the sector of the sector-shaped liquid outlet channel 311 is 60-80°.

[0066] Preferably, the central angle of the sector is 70°.

[0067] Preferably, the fan-shaped liquid outlet channel 311 is arranged to deviate from the connecting line by 10-40°.

[0068] like Figure 1 and Figure 2 As shown, the control panel seat 1 is provided with a clothing inlet, and the inner wall of the clothing inlet and the outer peripheral wall of the control panel seat 1 together enclose a cavity; the spray head 3 is arranged in the cavity, and the liquid outlet of the spray head 3 protrudes from the lower end of the control panel seat 1;

[0069] The pulsator washing machine also includes a detergent box 11, which is arranged in the cavity. The lower end of the detergent box 11 protrudes from the lower end of the control disc seat 1, the spray head 3 is circumferentially offset from the detergent box 11, and the fan-shaped liquid outlet channel 311 is offset to a side away from the detergent box 11.

[0070] Specifically, the control panel seat 1 is arranged at the upper part of the box body, the center of the control panel seat 1 is provided with the clothing loading port, and the control panel seat 1 is also provided with a foldable upper cover, which can be opened and closed to take out and put in clothing. The lower end of the detergent box 11 is located above the washing tub 2.

[0071] The liquid outlet of the spray head 3 is arranged to protrude from the lower end of the control disk seat 1, so that the fan-shaped water flow sprayed from the liquid outlet will not be blocked by the control disk seat 1. The spray head 3 is arranged to deviate from the detergent box 11 in the circumferential direction, and the fan-shaped liquid outlet channel 311 is arranged to be offset to a side away from the detergent box 11, so that the fan-shaped water flow will not be blocked by the detergent box 11, thereby avoiding waste.

[0072] like Figure 1 , Figure 5 and Figure 8 As shown, the two sides of the spray head 3 extending in the liquid outlet direction have different heights, and the side close to the connecting line is higher than the other side away from the connecting line.

[0073] In the above scheme, the heights of the two sides of the spray head 3 extending along the liquid outlet direction are different, so that the fan-shaped water flow can be sprayed with a certain inclination angle, and the heights of the two sides of the fan-shaped water flow sprayed on the inner wall of the washing tub 2 can be different. The fan-shaped water flow covers a larger area on the inner wall of the washing tub 2, which is beneficial to improving the rinsing effect.

[0074] Specifically, the washing tub 2 works simultaneously when the fan-shaped liquid outlet channel 311 sprays, and the two sides of the fan-shaped water flow spray at different heights on the inner wall of the washing tub 2, which can increase the spray range of the fan-shaped water flow in the vertical direction.

[0075] like Figure 8 , Fig. 9 and Fig.10 As shown, the fan-shaped liquid outlet channel 311 has a water outlet, and the water outlet has upper and lower edges. The end surface of the lower edge is provided with a chamfered surface 312, and the chamfered surface 312 is chamfered on the outer side wall of the lower edge of the water outlet.

[0076] In the above scheme, by setting the bevel surface 312 on the end face of the lower edge of the water outlet, the fan-shaped water flow will not splash to the two sides of the water outlet, and the fan-shaped water flow sprayed from the fan-shaped liquid outlet channel 311 will fall into the washing tub 2 and will not splash outside the washing tub 2, which is beneficial to improving the spraying effect of the fan-shaped liquid outlet channel 311 and is beneficial to water saving.

[0077] Preferably, the included angle between the beveled surface 312 and the fan-shaped liquid outlet channel 311 is 50-60°.

[0078] More preferably, the included angle between the beveled surface 312 and the fan-shaped liquid outlet channel 311 is 54.4°.

[0079] The spray head 3 includes a trumpet-shaped nozzle 31 and a connecting pipe 32 which are connected to each other.

[0080] The fan-shaped liquid outlet channel 311 is arranged in the trumpet-shaped nozzle 31 , and the connecting pipe 32 is arranged to extend transversely, with one end being connected to the water inlet of the fan-shaped liquid outlet channel 311 . A positioning column 321 is arranged in one end of the connecting pipe 32 .

[0081] The pulsator washing machine further comprises a water inlet pipe, one end of which is inserted into the connecting pipe 32 and abuts against the positioning column 321 . The water inlet pipe is communicated with the trumpet-shaped nozzle 31 .

[0082] Specifically, the trumpet-shaped nozzle 31 is flat, which can increase the impact force of the fan-shaped water flow, which is conducive to increasing the spraying distance of the fan-shaped water flow, so that it sprays on the inner peripheral wall of the washing tub 2. The cross-sectional area of ​​the fan-shaped liquid outlet channel 311 gradually increases along the liquid outlet direction, which is conducive to increasing the spraying range of the trumpet-shaped nozzle 31.

[0083] A reinforcing rib is provided between the connecting pipe 32 and the trumpet-shaped nozzle 31 to strengthen the connection strength between the connecting pipe 32 and the trumpet-shaped nozzle 31, thereby making the connection between the two firmly connected, reducing the distortion caused by the uneven stress due to the difference in wall thickness, and extending the service life of the connecting pipe 32 and the trumpet-shaped nozzle 31.

[0084] Specifically, the connecting pipe 32 is composed of two sections of pipes with different diameters, wherein the pipe with a smaller diameter is connected to the fan-shaped liquid outlet channel 311 in the trumpet-shaped nozzle 31. One end of the water inlet pipe is located in the pipe with a smaller diameter.

[0085] Preferably, the angle between the trumpet-shaped nozzle 31 and the connecting pipe 32 is 95-140°.

[0086] More preferably, the angle between the trumpet-shaped nozzle 31 and the connecting pipe 32 is 130°.

[0087] One end of the positioning column 321 is located at the connection between the flow channel in the connecting tube 32 and the fan-shaped liquid outlet flow channel 311 , and the other end of the positioning column 321 is extended along the direction in which the flow channel in the connecting tube 32 extends.

[0088] Preferably, the length of the positioning column 321 is 3 mm.

[0089] One end of the water inlet pipe extends into the connecting pipe 32 until it abuts against the positioning column 321. At this time, the water inlet pipe is fixed to the connecting pipe 32 to limit the installation position of the water inlet pipe, ensuring that the installation position of the water inlet pipe is unique, and the liquid in the water inlet pipe can maintain a suitable water volume and water pressure after entering the connecting pipe 32, so that it is guided by the trumpet-shaped nozzle 31 and then sprayed out in the best water type and falls on the inner wall of the washing tub 2, thereby achieving the best rinsing effect on the clothes.

[0090] like Figure 8 , Fig. 9 and Fig.10 As shown, the shower head 3 further includes a bracket 33 , one end of which is connected to the outer peripheral wall of the connecting pipe 32 , and the other end of the bracket 33 is extended upward and connected to the top wall of the control panel seat 1 .

[0091] Specifically, the bracket 33 is a box-shaped body without a cover, including a vertically arranged support plate, a fixing plate and four side plates arranged on the support plate, wherein the side plates are arranged opposite to each other and the opposite side plates are arranged in parallel. The support plate and the side plates are jointly surrounded by a groove.

[0092] The two side panels are arranged horizontally, the side panel located at the top is the first side panel, and the side panel located at the bottom is the second side panel, and the width of the first side panel is greater than the width of the second side panel. The fixing plate is connected between the first side panel and the second side panel, and one side of the fixing plate is connected to the support plate. One end of the fixing plate and the second side panel are both connected to the connecting pipe 32, which can strengthen the connection strength between the bracket 33 and the connecting pipe 32, make the connection between the two stable, and extend the service life of the bracket 33 and the connecting pipe 32. The guide column 331 is arranged at the upper end of the first side panel, and the guide column 331 and the first side panel are arranged through. An auxiliary plate is arranged at the lower end of the first side panel, and the first side panel and the auxiliary plate are arranged through mounting holes. The mounting holes can be used to install screws to connect the bracket 33 to the top wall of the cavity.

[0093] like Figure 2 , Figure 3 , Figure 8 and Fig.11 As shown, a guide column 331 is provided at the other end of the bracket 33, and the guide column 331 is extended upward. A positioning hole is provided in the guide column 331, and a positioning piece and a clamping piece are provided on the top wall of the control panel seat 1. The positioning piece is extended downward and plugged into the positioning hole, and the clamping piece is clamped with the other end of the bracket 33.

[0094] Specifically, a guide column 331 is provided at the upper end of the bracket 33, and a guide hole is provided in the guide column 331. A plurality of mounting blocks are arranged in a ring array in the guide hole, and a limit groove is formed between adjacent mounting blocks. The top wall of the cavity in the control panel seat 1 is provided with the positioning member and the clamping member, and the positioning member is plugged into the guide hole. The clamping member is provided with a clamping slot, and the other end portion of the bracket 33 is located in the clamping slot. The stacked thickness of the support plate and the first side plate is the same as the slot pitch of the clamping slot.

[0095] The positioning piece is plugged into the guide column 331, and the other end portion of the bracket 33 is engaged with the slot on the clamping piece, so that the installation position of the bracket 33 is unique, that is, the installation position of the spray head 3 is unique, and the water sprayed by the spray head 3 can cover the inner wall of the washing tub 2 to the maximum extent, so as to achieve a better rinsing effect.

[0096] like Fig.12 As shown, the present invention also provides a control method for a pulsator washing machine as described above, the control method comprising the following steps:

[0097] S1, start dehydration and rinsing;

[0098] S2, the sprinkler head sprays water for a preset time T1, and the washing tub operates at a preset speed V1;

[0099] S3, the sprinkler stops spraying water, and the washing tub operates at a preset speed V2 for a preset working time T2;

[0100] Among them, T1 <T2,V1<V2;

[0101] Repeat S2 and S3 until rinsing is completed.

[0102] Preferably, when the washing tub comprises an inner and outer tub, the inner tub rotates, and the fan-shaped water flow is sprayed onto the inner peripheral wall of the inner tub.

[0103] Specifically, after washing and dehydrating once, the clothes need to be rinsed to remove detergent and dirty water in the clothes.

[0104] The spray head sprays water, and the fan-shaped water flow sprays downwardly at an angle relative to the washing tub, and can cover the inner peripheral wall of the lower layer of the washing tub, so the fan-shaped water flow can soak the clothes closely attached to the inner peripheral wall of the lower layer of the washing tub.

[0105] In step S2, the spray head sprays water, and the washing tub operates at a relatively low rotation speed V1, so that the clothes closely attached to the inner peripheral wall of the lower layer of the washing tub can be soaked as much as possible.

[0106] In step S3, the washing tub operates at a high speed V2, and under the action of centrifugal force, the clean water can discharge the dirty water and detergent residue in the clothes.

[0107] Repeating steps S2 and S3 can perform multiple rinsing operations.

[0108] The water inlet flow rate of the sprinkler head is 6L / min, 20r / min≤V1≤40r / min, 700r / min≤V2≤800r / min.

[0109] Preferably, V1 is 30 r / min and V2 is 800 r / min.

[0110] The water inlet pipe is provided with a flow valve, and the flow valve can control the flow in the water inlet pipe.

[0111] Preferably, the flow rate in the water inlet pipe is 6 L / min.

[0112] The flow rate in the water inlet pipe is maintained at 6L / min, so that the sprinkler head can spray out the best water type.

[0113] During dehydration and rinsing, the spray head performs the first spraying for 2.5 minutes, and the washing barrel operates at a speed of 30r / min at the same time;

[0114] The spray head stops spraying, and the washing tub operates at high speed for dehydration for 6 minutes;

[0115] The spray head sprays for a second time for 2.5 minutes, and the washing tub operates at a speed of 30 r / min at the same time;

[0116] The spray head stops spraying, and the washing tub works at a high speed to dehydrate until the dehydration is finished.

[0117] After two spraying, rinsing and dehydration, detergent and dirty water in the clothes can be removed. The number of rinses can be adjusted according to user needs.
