[0030] This invention also provides a method for disassembling and assembling the bath towel of a reciprocating bath scrubber, comprising the following steps:

[0031] Step S1: The memory stores the maximum number of turns N of the single-sided bath towel roll to the bath towel consumable (60), and the number of turns N0 of the left side bath towel roll (40) when the machine was last turned off.

[0032] Step S2: When the control board (70) receives an instruction to disassemble or assemble the bath towel consumable (60), step S3 is executed.

[0033] In step S3, the control board (70) reads the switch signals of the left bath towel insertion detection switch (45) and the right bath towel insertion detection switch (55). If both the left bath towel insertion detection switch (45) and the right bath towel insertion detection switch (55) are off, it indicates that the left end of the current bath towel consumable (60) is inserted into the groove of the left bath towel roll (40), and at the same time, the right end of the bath towel consumable (60) is inserted into the groove of the right bath towel roll (50). Then, the bath towel disassembly process in step S4 is executed. Otherwise, if both the left bath towel insertion detection switch (45) and the right bath towel insertion detection switch (55) are on, it indicates that both ends of the current bath towel consumable (60) have been pulled out from the grooves of the left bath towel roll (40) and the right bath towel roll (50). Then, the bath towel installation process in step S5 is executed.

[0034] Step S4, Bath Towel Removal Process:

[0035] Step S4.1, the control board (70) reads the number of turns N0 of the left bath towel roll (40) when the machine was last turned off from the memory, thereby determining the rotation direction of the first roll and the number of turns of the first roll.

[0036] In step S4.2, the control board (70) controls the transmission device (30) according to the first roll rotation direction and the number of first roll rotations determined in step S4.1, thereby causing the left bath towel roll (40) and the right bath towel roll (50) to rotate the first roll rotations corresponding to the first roll rotation direction.

[0037] When the rotation stops, the grooves of the bath towel rolls on both sides are open and facing upwards. Furthermore, the bath towel roll on one side is no longer wrapped with the bath towel consumable (60), thus exposing the corresponding end of the bath towel consumable (60). At this time, the bath towel roll on the other side is wrapped with the maximum number of wrapping turns N.

[0038] Step S4.3, the control board (70) detects the switch signal of the bath towel insertion detection switch on the side of the currently exposed end of the bath towel consumable (60). When the signal is detected to be on, it indicates that the end of the exposed end of the bath towel consumable (60) has been pulled out from the groove of the bath towel roll.

[0039] Step S4.4, the control board (70) determines the rotation direction of the second roll of the bath towel roll unwound from the side where the end is not exposed;

[0040] In step S4.5, the control board (70) controls the transmission device (30) according to the second roll rotation direction determined in step S4.4, thereby causing the left bath towel roll (40) and the right bath towel roll (50) to rotate simultaneously in the second roll rotation direction for a maximum number of winding turns N.

[0041] When the rotation stops, the grooves of the bath towel rolls on both sides are open and facing upwards. In step S4.4, the bath towel roll on the side where the end is not exposed has been unwound from the bath towel consumable (60), and the corresponding end of the bath towel consumable (60) is exposed.

[0042] Step S4.6, the control board (70) detects the switch signal of the bath towel insertion detection switch on the side of the currently exposed end of the bath towel consumable (60). When the signal is detected to be on, it indicates that the end of the exposed end of the bath towel consumable (60) has been pulled out from the groove of the bath towel roll.

[0043] At this point, both ends of the bath towel consumable (60) have been pulled out of the grooves of the corresponding bath towel roll, and the left bath towel insertion detection switch (45) and the right bath towel insertion detection switch (55) are both on, completing the bath towel disassembly process;

[0044] Step S5, Bath Towel Installation Process:

[0045] Step S5.1, the control board (70) detects the switch signals of the left bath towel insertion detection switch (45) and the right bath towel insertion detection switch (55). When the detection signal of the bath towel insertion detection switch on one side changes from on to off, it indicates that the end of the bath towel consumable (60) on the corresponding side has been inserted into the groove of the bath towel roll on the corresponding side.

[0046] Step S5.2, the control board (70) determines the rotation direction of the third roll of the bath towel consumable (60) that is inserted into one side of the end of the bath towel consumable (60);

[0047] In step S5.3, the control board (70) controls the transmission device (30) according to the rotation direction of the third roll determined in step S5.2, so that the left bath towel roll (40) and the right bath towel roll (50) rotate simultaneously in the rotation direction of the third roll, with a maximum number of winding turns N.

[0048] When the rotation stops, the grooves of the bath towel rolls on both sides are open and facing upwards. The bath towel roll on the side that has been inserted into the end of the bath towel consumable (60) has been wrapped with the bath towel consumable (60) N times, and the groove of the bath towel roll on the other side is facing upwards and fully exposed.

[0049] Step S5.4, the control board (70) detects the switch signal of the bath towel insertion detection switch of the bath towel roll that currently exposes the groove. When the signal changes from an on signal to an off signal, it means that the groove of the bath towel roll on that side is inserted into the other end of the bath towel consumable (60).

[0050] At this point, both ends of the bath towel consumable (60) have been inserted into the grooves of the corresponding bath towel roll, completing the bath towel installation process.

[0051] Preferably, step S4.1 specifically includes:

[0052] If the number of turns N0 of the left bath towel roll (40) is greater than or equal to 2 / N when the machine is turned off most recently, then the rotation direction of the left bath towel roll (40) around the bath towel consumable (60) is the rotation direction of the first roll. At this time, the number of turns of the first roll is N-N0.

[0053] If the number of turns N0 of the left bath towel roll (40) is less than 2 / N when the machine is last turned off, the rotation direction of the left bath towel roll (40) unwinding the bath towel consumable (60) is the rotation direction of the first roll. At this time, the number of turns of the first roll is N0.

[0054] Preferably, after step S5.4, a protective wrapping operation is further included, comprising:

[0055] Step S5.5: Based on the order in which the bath towel consumable (60) is inserted into the bath towel roll during installation, a protective wrapping measure is taken: If the end of the bath towel consumable (60) is inserted into the groove of the left bath towel roll (40) first during installation, it means that N turns were wrapped counterclockwise on the left bath towel roll (40) during installation, and the protective wrapping direction is set to clockwise; otherwise, the protective wrapping direction is set to counterclockwise; the number of protective wrapping turns is 1 in both cases.

[0056] In step S5.6, the control board (70) controls the transmission device (30) according to the determined protective winding direction and the number of protective winding turns, thereby causing the left bath towel roll (40) and the right bath towel roll (50) to rotate 1 turn simultaneously in the protective winding direction for protection.

[0057] Then, the number of wraps of the current left-side bath towel roll (40) and the rotation direction parameter after power-on are saved in the memory, and the machine enters the power-off standby state; wherein, the rotation direction parameter after power-on is the same as the protective wrapping direction.

[0058] The present invention provides an easy-to-disassemble and assemble device and method for a reciprocating bath scrubber towel, which has the following advantages:

[0059] It is very convenient to disassemble and replace the bath towel, and the operation is simple and quick; the bath towel roll structure of this application is simple and has low manufacturing cost, and the bath towel is only replaced as a consumable, thereby reducing the operating cost of the bath scrubber; and when replacing the bath towel, it can prevent accidental operation that could cause the bath towel to become tangled and clogged or damage the bath scrubber, which can improve user satisfaction.

Furthermore, the transmission unit 31 can be multiple driven gears; the driving gear 21 of the driver 20 meshes with multiple driven gears of the transmission device 30, and then meshes with the left transmission gear 43 of the left bath towel roll 40 and the right transmission gear 53 of the right bath towel roll 50, thereby driving the left bath towel roll 40 and the right bath towel roll 50 to rotate synchronously and in the same direction through the driver 20 and the transmission device 30.

[0087] This invention provides a method for assembling and disassembling the bath towel of a reciprocating bath scrubber, comprising the following steps:

[0088] Step S1: The memory stores the maximum number of turns N of the single-sided bath towel roll 40 around the bath towel consumable 60, and the number of turns N0 of the left-side bath towel roll 40 when the machine was last turned off.

[0089] Step S2: When the control board 70 receives an instruction to disassemble or assemble the bath towel consumable 60, step S3 is executed.

[0090] In step S3, the control board 70 reads the switch signals of the left bath towel insertion detection switch 45 and the right bath towel insertion detection switch 55. If both the left and right bath towel insertion detection switches 45 and 55 are off, it indicates that the left end of the bath towel consumable 60 is inserted into the groove of the left bath towel roll 40, and the right end of the bath towel consumable 60 is inserted into the groove of the right bath towel roll 50. Then, the bath towel disassembly process in step S4 is executed. Otherwise, if both the left and right bath towel insertion detection switches 45 and 55 are on, it indicates that both ends of the bath towel consumable 60 have been pulled out from the grooves of the left and right bath towel rolls 40 and 50. Then, the bath towel installation process in step S5 is executed.

[0091] Step S4, Bath Towel Removal Process:

[0092] Step S4.1, the control board 70 reads the number of turns N0 of the left bath towel roll 40 when the machine was last turned off from the memory, thereby determining the rotation direction of the first roll and the number of turns of the first roll.

[0093] Step S4.1 is as follows:

[0094] If the number of turns N0 of the left bath towel roll 40 is greater than or equal to 2 / N when the machine is last turned off, then the rotation direction of the left bath towel roll 40 around the bath towel consumable 60 is the rotation direction of the first roll. At this time, the number of turns of the first roll is N-N0.

[0095] If the number of turns N0 of the left bath towel roll 40 is less than 2 / N when the device was last turned off, then the rotation direction of the left bath towel roll 40 unwinding the bath towel consumable 60 is the rotation direction of the first roll. At this time, the number of turns of the first roll is N0.

[0096] In step S4.2, the control board 70 controls the transmission device 30 according to the first roll rotation direction and the number of first roll rotations determined in step S4.1, thereby causing the left bath towel roll 40 and the right bath towel roll 50 to rotate the corresponding number of first roll rotations in the first roll rotation direction.

[0097] When the rotation stops, the grooves of the bath towel rolls on both sides are open and facing upwards. Furthermore, the bath towel roll on one side is no longer wrapped with the bath towel consumable 60, thus exposing the corresponding end of the bath towel consumable 60. At this time, the bath towel roll on the other side is wrapped with the maximum number of wraps N.

[0098] Step S4.3, the control board 70 detects the switch signal of the bath towel insertion detection switch on the side of the exposed end of the bath towel consumable 60. When the signal is detected to be on, it indicates that the end of the exposed end of the bath towel consumable 60 has been pulled out from the groove of the bath towel roll.

[0099] Step S4.4, the control board 70 determines the rotation direction of the second roll of the bath towel consumable 60 that is not exposed on the side of the end of the bath towel roll to unwrap the second roll of the bath towel consumable 60.

[0100] In step S4.5, the control board 70 controls the transmission device 30 according to the second roll rotation direction determined in step S4.4, thereby causing the left bath towel roll 40 and the right bath towel roll 50 to rotate simultaneously in the second roll rotation direction for the maximum number of winding turns N.

[0101] When the rotation stops, the grooves of the bath towel rolls on both sides are open and facing upwards. In addition, the bath towel roll on the side whose end is not exposed in step S4.4 has been unwound from the bath towel consumable 60, and the corresponding end of the bath towel consumable 60 is exposed.

[0102] Step S4.6, the control board 70 detects the switch signal of the bath towel insertion detection switch on the side of the exposed end of the bath towel consumable 60. When the signal is detected to be on, it indicates that the end of the exposed end of the bath towel consumable 60 has been pulled out from the groove of the bath towel roll.

[0103] At this point, both ends of the bath towel consumable 60 have been pulled out of the grooves of the corresponding bath towel roll, and the left bath towel insertion detection switch 45 and the right bath towel insertion detection switch 55 are both on, completing the bath towel disassembly process.

[0104] Step S5, Bath Towel Installation Process:

[0105] Step S5.1, the control board 70 detects the switch signals of the left bath towel insertion detection switch 45 and the right bath towel insertion detection switch 55. When the detection signal of the bath towel insertion detection switch on one side changes from on to off, it indicates that the end of the bath towel consumable 60 on the corresponding side has been inserted into the groove of the bath towel roll on the corresponding side.

[0106] Step S5.2, the control board 70 determines the rotation direction of the third roll of the bath towel spool that has been inserted into one end of the bath towel consumable 60 and is winding around the bath towel consumable 60.

[0107] In step S5.3, the control board 70 controls the transmission device 30 according to the rotation direction of the third roll determined in step S5.2, thereby causing the left bath towel roll 40 and the right bath towel roll 50 to rotate simultaneously in the rotation direction of the third roll for the maximum number of winding turns N.

[0108] When the rotation stops, the grooves of the bath towel rolls on both sides are open and facing upwards. The bath towel roll on the side that is currently inserted into the end of the bath towel consumable 60 has been wrapped around the bath towel consumable 60 N times, while the groove of the bath towel roll on the other side is facing upwards and fully exposed.

[0109] Step S5.4, the control board 70 detects the switch signal of the bath towel insertion detection switch of the bath towel roll that currently exposes the groove. When the signal changes from an on signal to an off signal, it means that the groove of the bath towel roll on that side is inserted into the other end of the bath towel consumable 60.

[0110] At this point, both ends of the bath towel consumable 60 have been inserted into the grooves of the corresponding bath towel roll, completing the bath towel installation process.

[0111] As a further improvement: after step S5.4, a protective wrapping operation is also included, including:

[0112] Step S5.5: Based on the order in which the bath towel consumable 60 is inserted into the bath towel roll during installation, a protective wrapping measure is performed: If the end of the bath towel consumable 60 is inserted into the groove of the left bath towel roll 40 first during installation, it means that N turns were made counterclockwise around the left bath towel roll 40 during installation, and the protective wrapping direction is set to clockwise; otherwise, the protective wrapping direction is set to counterclockwise; the number of protective wrapping turns is 1 in both cases.

[0113] In step S5.6, the control board 70 controls the transmission device 30 according to the determined protective winding direction and the number of protective winding turns, thereby causing the left bath towel roll 40 and the right bath towel roll 50 to rotate one turn simultaneously in the protective winding direction for protection.

[0114] Then, the current number of wraps on the left side of the bath towel roll 40 and the rotation direction parameters after power-on are saved in the memory, and the machine enters the power-off standby state; wherein, the rotation direction parameters after power-on are the same as the protective wrapping direction.

[0115] The following is a specific example:

When the rotation stops, the grooves of the bath towel rolls on both sides are open and facing upwards. In addition, the bath towel roll on the side whose end is not exposed in step S4.4 has been unwound from the bath towel consumable (60), and the corresponding end of the bath towel consumable (60) is exposed. Step S4.6, the control board (70) detects the switch signal of the bath towel insertion detection switch on the side of the currently exposed end of the bath towel consumable (60). When the signal is detected to be on, it indicates that the end of the exposed end of the bath towel consumable (60) has been pulled out from the groove of the bath towel roll. At this point, both ends of the bath towel consumable (60) have been pulled out of the grooves of the corresponding bath towel roll, and the left bath towel insertion detection switch (45) and the right bath towel insertion detection switch (55) are both on, completing the bath towel disassembly process; Step S5, Bath Towel Installation Process: Step S5.1, the control board (70) detects the switch signals of the left bath towel insertion detection switch (45) and the right bath towel insertion detection switch (55). When the detection signal of the bath towel insertion detection switch on one side changes from on to off, it indicates that the end of the bath towel consumable (60) on the corresponding side has been inserted into the groove of the bath towel roll on the corresponding side. Step S5.2, the control board (70) determines the rotation direction of the third roll of the bath towel consumable (60) that is inserted into one end of the bath towel consumable (60); In step S5.3, the control board (70) controls the transmission device (30) according to the rotation direction of the third roll determined in step S5.2, so that the left bath towel roll (40) and the right bath towel roll (50) rotate simultaneously in the rotation direction of the third roll, with a maximum number of winding turns N. When the rotation stops, the grooves of the bath towel rolls on both sides are open and facing upwards. The bath towel roll on the side that has been inserted into the end of the bath towel consumable (60) has been wrapped with the bath towel consumable (60) N times, and the groove of the bath towel roll on the other side is facing upwards and fully exposed. Step S5.4, the control board (70) detects the switch signal of the bath towel insertion detection switch of the bath towel roll that currently exposes the groove. When the signal changes from an on signal to an off signal, it means that the groove of the bath towel roll on that side is inserted into the other end of the bath towel consumable (60). At this point, both ends of the bath towel consumable (60) have been inserted into the grooves of the corresponding bath towel roll, completing the bath towel installation process.
