Description

Technical Field

[0001] This utility model belongs to the field of shoe washing technology, and in particular relates to a shoe washing machine that can simultaneously clean the insoles inside and outside of shoes. Background Technology

[0002] As living standards continue to improve, people have higher and higher requirements for shoe cleaning efficiency. In the past, people usually used brushes to manually wash shoes, which was time-consuming and laborious. To free people from manual shoe washing, many shoe washing machines have emerged. However, most shoe washing machines currently on the market use an in-machine agitation method, where shoes are agitated and rinsed with water flow. The main problem with this method is that the inside of the shoe and the insole are difficult to clean thoroughly, resulting in an unsatisfactory cleaning effect. Furthermore, during the spin-drying process, the shoes may shake and collide significantly within the machine, causing considerable noise or even causing the shoes to be thrown out, making the overall performance less than ideal.

[0046] The present invention will be further explained below with reference to specific embodiments and accompanying drawings.

[0047] The pushing and washing mechanism of this utility model (such as...) Figure 1-4 As shown, serial numbers 7 and 8 are push-wash motors (i.e., the first motor and the second motor). The first motor 7 and the second motor 8 are fixed to the lower part of the cover 1. The first movable rod 9 and the second movable rod 10 are stacked and respectively connected to the central shaft 6 by two bearings 22. In the initial state, the two movable connecting rods intersect at 90 degrees.

[0048] The first end of the second movable rod 10 is provided with a return motor 20, the shaft end of the return motor 20 is provided with a return drive gear 11, and a solenoid valve 21 and a shift fork 24 driven by the solenoid valve 21 are provided next to the return motor. The shift fork 24 can move the return drive gear 11 up and down to control whether the return drive gear 11 and the return gear 12 are engaged.

[0049] A return gear 12 is fixedly provided at the lower end of the central shaft 6, and a first bearing 19 is provided at the upper end of the central shaft 6. The outer ring of the first bearing 19 is connected to a cross movable frame 5 by rolling hinge. A thermal delay mechanism 16 is provided at the second end of the first movable rod 9. A sliding positioning tooth 15 is provided on the thermal delay mechanism 16. The sliding positioning tooth 15 meshes with the locking gear 17 fixed on the central shaft 6.

[0050] A magnet 14 for position detection is provided at the upper end of the central shaft 6, and a magnetic sensor 4 that can interact with the magnet 14 is provided inside the lifting frame 2.

[0051] Figure 1-4The push-wash mechanism is described using the push-wash motor (first motor 7) as an example. It is achieved through the rolling engagement of the outer ring of the rotary seat 13 and the bearing 25 (set on the output shaft of the first motor 7). A gear 23 is fixedly connected to the output shaft of the first motor 7. The first movable rod 9 is slidably connected to the rotary seat 13. The gear 23 meshes with the rack 18 inside the first movable rod 9. The first movable rod 9 can rotate together with the rotary seat 13 through the bearing 25. It can also drive the rack 18 to move back and forth along the length of the first movable rod 9 through the rotation of the gear 23. It can also swing left and right along the bearing 25. In addition, the working principle of the first motor 7 and the second movable connecting rod 10 is the same.

[0052] A lifting frame 2 is fixedly installed on the inner surface of the cover 1. Each lifting frame has 4 straight slots 3. A magnetic sensor 4 is installed at the center of the lifting frame 2. Each support rod of the cross movable frame 5 passes through the straight slots 3 and is limited to move within the straight slots 3.

[0053] The magnetic sensor 4 is set to be perpendicular to the position of the cover pivot pin to detect whether the shoe-shaped brush disc 129 deviates in direction after operation.

[0054] Description of the push-wash mechanism's movement: The first and second motors are fixed to the inner surface of the cover 1. The cross-shaped movable plate 5 is slidably connected to the straight groove 3 of the lifting frame 2 on the inner surface of the cover 1, forming a sliding structure. The first and second motors, through the cooperation of bearings 25, gears 23, racks 18, and rotary seats 13, form a moving mechanism. The first and second motors rotate forward and backward according to a certain pattern, and their operating speeds are set to be different. The movement trajectory of the central shaft 6 and the shoe sole-shaped brush plate 129 is set to an ellipse, see... Figure 20 As shown.

[0055] Shoe sole-shaped cleaning plate 129 (see) Figure 12 , 13 As shown, the shoe sole-shaped brushing disc 129 is provided with shoe sole bristles 26, shoe-shaped inclined surface 27, and water drain holes 28 and 29. The shoe sole-shaped brushing disc is fixedly connected to the lower part of the central shaft 6. A water inlet pipe 127 connected to tap water is provided on the upper right part of the machine body. After water enters, the water flows into the washing tub 68 through the water drain holes 28 and 29.

[0056] A rubber sleeve 40 is provided between the cover 1 and the shoe sole-shaped brushing disc 129 and on the periphery of the push washing mechanism. A cover pin 41 is provided on the cover 1 and is rotatably connected to the machine body. The cover 1 is flipped up through the cover pin 41 to open the cover and realize the taking and putting of shoes.

[0057] In the figure, 42 is the toe part. The line connecting the two toes is parallel to the cover pin 41. During washing, the two sole-shaped brush discs cannot rotate along the central axis 6 of the washing mechanism. Only when the heat-sensitive delay mechanism is energized during spin drying and the positioning teeth 15 are pulled back can the sole-shaped brush discs rotate together with the central axis 6. The positioning teeth 15 are engaged with the locking gear 17 when they are not pulled back.

[0058] The overall operation of the push-wash mechanism on the machine cover is as follows: During operation, the first motor 7 and the second motor 8 rotate. Motor 7 starts from point O and moves in the direction of the arrow to point D. The first motor 7 and the second motor 8 simultaneously move to the end of line segment A to point E. The first motor 7 and the second motor 8 then move along contour segment B to point F using elliptical interpolation at different speeds. The same method is repeated continuously in the direction of the arrow along the solid line in the diagram to point D, i.e., a full circle operation. This continues until the washing is finished, and then the mechanism returns from point D to point O. The trajectory diagram in the figure shows the washing trajectory of the washing disc. Figure 20 The brushing trajectory can be adjusted by changing the stroke of the push-wash motor according to the selected shoe size, so that the dimensions A, B, and C in the trajectory diagram can be increased or decreased to complete the process. When running this brushing trajectory, the thermal delay mechanism 16 does not operate, the positioning gear 15 and the locking gear 17 on the central shaft 6 are engaged, and the central shaft 6 cannot rotate circumferentially.

[0059] During operation, the first motor 7 and the second motor 8 rotate, and the gear 23 on their output shafts drives the rack 18 to rotate through the rotary seat 13, pushing the central shaft 6 in the sliding engagement between the cross-shaped movable frame 5 and the straight slot 3. Figure 20 The trajectory shown is the running path.

[0060] In summary: the central shaft 6 moves along the solid line in the direction of the arrow with point O as the center, and the opposite direction is also possible. During this period, the positioning gear 15 and the locking gear 17 on the central shaft 6 mesh, locking the central shaft 6. That is, the central shaft 6 cannot rotate at this time, and the thermal delay mechanism is not energized. Because the sole-shaped brush plate is fixed to the lower end face of the central shaft 6, the movement trajectory of the sole-shaped brush plate is similar to... Figure 20 The results are exactly the same.

[0061] Washing tub part: such as Figure 22 , 23 The washing tub 68 shown can be cylindrical, with a groove 62 on the outer cylinder. One side of the washing tub is open, and the inner wall of the tub is provided with bristles 64. There is a central bristle frame 63. The bristles on the central bristle frame 63 and the bristles on the inner wall of the tub are both made of soft silicone, and together with the bristles on the inner wall of the tub, they form a three-dimensional brush cavity 60 in the shape of a shoe upper (this cavity completely matches the outer surface of the shoe). There is a circulating water outlet 65 that is directly opposite the groove 62. The bottom of the tub is provided with two inner brush body sockets 82 for inserting hollow sleeve rods 52 for inserting shoe inner brushes 53 (that is, the inner brush body sockets 82 have insertion holes). The insertion holes are provided with positioning key grooves 70 that cooperate with the positioning keys 56 on the hollow sleeve rods 52.

[0062] The bottom of the washing tub is designed to be hollow. At the center of the bottom of the tub, there is a pump housing 71, a water outlet 81, and a pump inlet 84. The two inner brush sockets 82 on the bottom of the tub are provided with reinforcing ribs 67.

[0063] The shoe inner brush 53 has a hollow sleeve rod 52. A spring 55 is provided on the outer periphery of the hollow sleeve rod 52. The spring 55 is fixed on the step on the outer periphery of the sleeve rod 52. A positioning key 56 is provided on the lower outer periphery of the hollow sleeve rod 52. A water inlet 51 is provided on the lower part of the hollow sleeve rod 52. The shoe inner brush 53 is provided at the upper end of the hollow sleeve rod 52. The shoe inner brush 53 is hollow. The cavity is connected to the inner hole of the hollow sleeve rod 52. The outer periphery of the shoe inner brush 53 has bristles 54 and water outlet 50. When brushing, the impeller combination pump presses water into the cavity of the shoe inner brush 53, sprays it out from the water outlet 50 and sprays it into the shoe inside the shoe fitted on the shoe inner brush 53.

[0064] like Figure 21 The impeller pump shown is equipped with a drum wall pump blade 91, a center pump blade 90, an impeller 93, and a center pump housing 94. Its operating principle in conjunction with the washing drum and the spin-drying drum is detailed below.

[0065] like Figure 27 , 28 The dehydration bucket 85 shown is provided with a bottom drain hole 73 and a central through hole 76, and the bucket wall is provided with a positioning guide groove 74, a bucket wall water outlet hole 77 and a bucket wall water pumping channel 75.

[0066] See the assembly of the spin-dry tub 85 and the washing tub 68. Figure 28 , 29 The dehydration tub 85 is the outer tub, and the washing tub 68 is the inner tub. The groove 62 of the washing tub fits into the positioning guide groove 74 of the dehydration tub 85. The bottom of the washing tub is attached to the upper surface of the pump water channel 75 on the tub wall of the dehydration tub, forming a dehydration, brushing, and pumping integrated tub. This tub can be disassembled according to the assembly sequence. The integrated tub has a central pump assembly 80, a pump body inlet 84, and a pump water channel 81. Water in the washing tub 68 is pumped into the cavity of the shoe inner brush 53 through the pump body inlet 84, the pump water channel 81, and the hollow sleeve rod 52, and sprayed out from the water outlet 50. 83 is the tub body pump water channel, which is composed of the tub wall pump blade 91 and the tub wall pump water channel 75 of the dehydration tub 85 (i.e., a combined pump). The pump water outlet is 86.

[0067] The inner wall of the spin-dry tub 85 is provided with a tub wall pumping channel 75 and a positioning guide groove 74. The tub wall of the washing tub 68 is provided with a groove 62 that cooperates with the positioning guide groove 74. The bottom of the washing tub 68 is attached to the upper surface of the tub wall pumping channel 75. The inner wall of the washing tub 68 is provided with a circulating water outlet 65 that is connected to the tub wall pumping channel 75. The wall of the circulating water outlet 65 is densely covered with pumping water outlets 86. The tub wall pump blade 91 provided on the impeller pump and the tub wall pumping channel 75 of the spin-dry tub 85 form a tub body pumping channel 83. When the impeller pump rotates, it pumps water into the tub wall pumping channel 75 through the tub wall pump blade 91, and sprays it out through the circulating water outlet 65 and the pumping water outlets 86 in sequence.

[0068] Figure 19The internal structure of the assembly drawing is shown in this diagram for explanation of the principle: When in use, the cover lock 130 is in the unlocked state. First, the cover 1 with the push-wash mechanism is flipped upward along the shaft 125 (with the cover shaft pin 41) at an angle of 60-90 degrees. Take out the shoe inner brush 53, put the shoe to be cleaned on the shoe inner brush 53, and then insert the shoe inner brush together with the shoe into the hole of the inner brush body socket 82. Repeat the same operation for both shoes. The shoe inner brush 53 cannot rotate in the inner brush body socket 82. The hollow sleeve 52 of the shoe inner brush 53 has a positioning key 56 on the outside, which slides up and down with the positioning keyway in the inner brush body socket 82, but cannot rotate relative to the circumference. The initial position is the mutual sensing position of the magnetic induction sensor above the central shaft of the push-wash mechanism, so that the line 42 connecting the two shoe toes of the sole brush washing plate is parallel to the cover shaft pin 41, and the line 42 connecting the shoe toes is on the side away from the cover shaft pin. At this point, the magnetic induction sensor and magnet 120 at the bottom of the water tank 137 are in a mutually inductive position, meaning the toes of the shoe-shaped brush and the shoe-shaped inner brush are in the same direction. After the shoe is placed in, the machine cover 1 is flipped down and pressed down. At this time, the sole of the shoe to be cleaned is inserted into the sole-shaped brush 27 with the sole facing upwards. Simultaneously, the shoe-shaped inner brush 53 passively moves downwards to compress the spring 55 until the machine cover is in place. At this time, the upper part of the shoe is pressed into the upper-shaped three-dimensional brush cavity 60. Then, the machine cover lock 130 locks. Lock 130 is a combination of a mechanical lock and a thermal delay mechanism lock. After pressing down, the mechanical lock latches the cover 1. When the whole machine is started, the thermal delay mechanism is energized and locks (the above-mentioned thermal delay mechanism and mechanical lock locking the machine cover are existing technologies and will not be described in detail here). After completion, it is ready to start. After starting, water is injected into the water inlet pipe 127. Water falls from the drain holes 28 and 29 on the upper part of the sole-shaped brush 27 into the water tank 137. Both the spin-dry tub and the washing tub are located inside the water storage tank (this structure is the same as that of existing pulsator washing machines). After the water level exceeds the central pump body 123, the pulsator disc starts to operate first. The central pump body 123 pushes water through the pump body inlet 84, the pump channel 81, and the hollow sleeve rod 52 of the shoe inner brush into the shoe inner brush 53. The water is then sprayed into the shoe inside to be cleaned from the water outlet 50 of the shoe inner brush. At the same time, the tub wall pressure pump 126 pushes water into the tub wall pump channel 75 and outputs it from the pump outlet 86 (the wall surface of the tub wall pump channel 75 is densely covered with pump outlets 86), spraying it onto the outside of the shoe surface, completing the wet shoe washing process. The brushing begins. Since the shoe inner brush 53 is stationary, the washing tub is also stationary, and the shoe upper three-dimensional brush cavity inside the washing tub is stationary. Then, the first motor 7 and the second motor 8 in the brushing mechanism on the machine cover work together to push the shoe sole brush washing disc 129 to perform a predetermined movement, that is, the shoes being cleaned are being washed. Figure 20The solid line trajectory action, or brushing, involves relative movement with the shoe's inner brush and the three-dimensional brush cavity to complete the brushing. Inside the washing tub, the shoe moves at a frequency of 30-60 times per minute under the interaction of the shoe's inner brush 53 and the silicone soft bristles 64 forming the shoe's upper-shaped three-dimensional brush cavity 60. Simultaneously, the central impeller pump 123 and the tub wall pressure pump 126 pump water, resulting in both brushing by the cover brushing mechanism and rinsing by the water flow. This combination of methods ensures rapid and thorough cleaning.

[0069] It should be noted that the water tank 137 is elastically connected to the spring 136 inside the outer casing 131. Since this machine only washes one pair of shoes, it is relatively light overall.

[0070] After cleaning, the foam rinsing process is the same as the cleaning process.

[0071] Spin-drying process: The spin-drying drive mechanism is the same as that of existing pulsator washing machines, including a connected drive motor (not shown in the figure), clutch 135, drain actuator 121 (this drain actuator is a power-off holding type, i.e., pulled back when energized, held when de-energized, and reset when energized again), and drain valve 122. The drive motor, clutch 135, drain actuator 121, and drain valve 122 are installed on the bottom of the water tank 137, and are completely enclosed in the housing 131. The drive motor is connected to the pulley 124 on the clutch 135 via a transmission belt, and the drain valve 122 is used to control the drainage of the water tank 137. It should be noted that the drive motor, clutch, drain actuator, and drain valve are all widely used in existing pulsator washing machines, and their specific construction and connection relationships are well known in the art, and will not be repeated here.

[0072] After the water is drained, the drain puller 121 continues to operate, pulling open the brake lever 133 and the drain valve 122, and simultaneously disengaging the retaining spring gear 134, causing the clutch washing shaft and the spin-drying shaft flange to rotate simultaneously. The spin-drying tub 85 rotates, causing the shoe inner brush 53 to rotate as well. The shoe is positioned between the shoe inner brush 53 and the shoe sole shaped brush washing disc 129 (as explained above, the hollow sleeve rod 52 of the shoe inner brush 53 has a positioning key 56 on its outer cylinder). Under the force of the spring 55, the shoe sole shaped upper 27 is pressed against the shoe sole. After the washing mechanism on the machine cover finishes cleaning, the motors 7 and 8 rotate, causing the shaft to press... Following the trajectory shown in the diagram, the spin-drying drum returns to point O, which is the center point of the machine cover and also the center of rotation of the spin-drying drum. (The three center points are on the same line.) When the spin-drying drum returns to the center of rotation, the thermal delay electric mechanism 16 in the push-wash mechanism is energized, the positioning gear 15 retracts, and separates from the locking gear 17. At this time, under the action of the first bearing 19 and the bearing 22, the spin-drying drum can rotate freely, that is, the shoe sole-shaped brush 129 can rotate freely along with the spin-drying drum. When the spin-drying drum rotates slowly, it drives the shoe sole-shaped brush 129 to rotate, slowly accelerating the spin-drying process until it is complete. If there is a sudden power failure during spin-drying, the thermal delay mechanism 16 will not immediately recover, the positioning gear 15 will not immediately return to its position, and the spin-drying traction device is a power failure retention type. The spin-drying drum can continue to rotate. After the spin-drying drum and the shoe sole-shaped brush 129 stop freely, the thermal delay mechanism 16 cools down and resets, the positioning gear 15 and the locking gear 17 mesh, and the spin-drying drum 6 is locked.

[0073] Additionally, there is a position adjustment function. The toe positions of the sole-shaped brush 129 and the inner shoe-shaped brush 53 are parallel and in the same direction, with the toe position opposite to the rotation axis 125 of the cover 1. If the sole-shaped brush 129 and the inner shoe-shaped brush 53 rotate to different positions during use, the adjustment method is as follows: After cleaning, open the cover 1 or remove the shoes, check if the positions of the magnetic sensor 4 inside the cover 1 and the magnet 14 at the upper end of the central shaft 6 of the push-wash mechanism are consistent. If they are inconsistent, the thermal delay mechanism 16 is energized to retract the positioning teeth 15. The positioning gear 15 and the locking gear 17 are separated. Then, the return motor 20 is driven by the circuit to rotate the return drive gear 11, and at the same time, the electromagnet 21 is driven to push out the shift fork 24, which meshes the return drive gear 11 and the return gear 12, causing the central shaft 6 to rotate. The central shaft 6 drives the shoe sole-shaped push-wash plate to rotate. When the magnetic sensor detects the signal of the magnet on the upper part of the central shaft 6, the return motor stops rotating, and the electromagnet 21 continues to be energized until the thermal electric mechanism cools down and returns to its original position, so that the positioning gear 15 and the locking gear 17 re-mesh. After locking, the electromagnet 21 is de-energized and resets.

[0074] It should be noted that the first motor 7, the second motor 8, and the motor 20 are all equipped with a reduction gear mechanism. This mechanism has a self-locking function, that is, it starts to move when there is an electrical signal and stops when there is no electrical signal, and external force cannot make it rotate.

[0075] The method for returning the spin-dry tub (i.e., washing tub) to its original position is as follows: After washing or when the machine lid is opened, the lid opening sensor is inside the lid lock 130. When the position detection sensor 132 no longer detects the position magnet 120, the drain actuator 121 is energized, opening the drain valve 122 and clutch brake 133. Simultaneously, the shift fork disengages the shaft gear 134, connecting the pulley 124 to the spin-dry tub 85. At this time, the motor drives the pulley 124 to rotate slowly, causing the washing tub and the shoe brush 53 inserted in the washing tub 68 to rotate until the position electromagnet 120 is detected by the electromagnetic sensor 132. The motor then stops rotating, and the drain actuator 121 resets. This return method is based on electrical system detection and voice prompts; simply close the lid. No manual operation is required.

[0076] The above description is only a preferred embodiment of the present utility model. Without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be considered within the protection scope of the present utility model.
