In addition, the shoe washing machine 1 further includes a control device capable of performing the shoe size detection method for the shoe washing machine described in the preferred embodiment.
Further, the brush wheel 11 is further arranged below the moving device 12, the moving device 12 can drive the brush wheel 11 to move synchronously, and the moving device 12 is further provided with an adaptive device, so that the brush wheel 11 can always contact with the surface of the shoe to be tested with proper pressure in the moving process, and the surface of the shoe to be tested is protected from being damaged. It is understood that other power means than the driving motor 13 may be used for the moving means 12, and that such power means may be modified without departing from the measuring principle of the present invention and shall fall within the scope of the present invention.
The method of the present invention will be described in detail below by taking as an example a process in which the shoe washing machine 1 operates the shoe size detecting method of the present invention. In the following preferred technical solution, the moving device 12 is in adaptive contact with the shoe to be measured through the brush wheel 11, so as to measure the size of the shoe to be measured. It is understood that although the shoe washing machine 1 of the present invention is in contact with the shoe to be tested by means of the brush wheel 11 provided on the moving device 12, the shoe washing machine 1 can obviously also be in contact with the shoe to be tested by means of other elements, and such a change of the contact element does not depart from the measuring principle of the present invention and should fall within the protection scope of the present invention.
It can be understood by those skilled in the art that the above description of the structure of the shoe washing machine 1 is not limiting, and the present invention does not impose any limitation on the structure of the shoe washing machine 1 as long as the shoe washing machine 1 can measure the size of the shoe to be measured using the shoe size detection method of the present invention. Therefore, any description of the structure of the shoe washing machine 1 should not be construed as limiting the scope of the present invention, as long as the method of measuring the size of the shoe to be measured by the shoe washing machine 1 does not deviate from the measuring principle of the present invention.
Next, the present preferred embodiment will describe in detail the shoe size detecting method of the present invention with reference to the process of operating the shoe size detecting method of the present invention in conjunction with the shoe washing machine 1 of FIG. 1 as an example; referring next to fig. 2, there is shown a flowchart of a shoe size detecting method for a shoe washing machine according to the present invention. As shown in fig. 2, the method mainly comprises the following steps:
s101: starting the mobile device;
s102: acquiring the running current of a motor of the mobile device;
s103: judging whether the running current of the motor suddenly increases relative to a preset current or not; if yes, executing step S104; if not, step S102 is executed again;
s104: acquiring the time point as a first time point;
s105: acquiring the running current of a motor of the mobile device;
s106: judging whether the running current of the motor is suddenly reduced to a preset current or not; if yes, go to step S107; if not, step S105 is executed again;
s107: acquiring the time point as a second time point;
s108: calculating the time difference value between the second time point and the first time point;
s109: acquiring the rotating speed of a motor, and calculating the moving speed of the mobile device;
s110: and calculating the moving distance of the mobile device, and determining the size of the shoe to be measured.
Specifically, as shown in fig. 1, in step S101, first, the shoe washing machine 1 is started so that the motor 13 can drive the moving device 12 to move on the moving rail 14. Wherein, the length of the moving track 14 is greater than the length of the largest shoe to be tested, therefore, in the whole moving process of the moving device 12, the brush wheel 11 can contact with the whole shoe to be tested, so as to obtain the contact state of the shoe washing machine 1 and the shoe to be tested, and calculate the size of the shoe to be tested according to the obtaining result of the contact state.
It can be understood that the shoe washing machine 1 can accurately calculate the size of the shoe to be detected by the shoe size detection method of the invention, so that the mobile device 12 can complete mobile washing of the shoe to be washed only by moving within the length range of the shoe to be washed, thereby greatly improving the washing efficiency of the shoe washing machine 1 and reducing the washing energy consumption. In addition, although the moving device 12 in the preferred embodiment is contacted with the shoe to be tested through the brush wheel 11, it is obvious that the moving device 12 can also be contacted with the shoe to be tested through other elements.
Further, in step S102, the operation current for driving the motor 13 of the mobile device 12 is acquired in real time. It can be understood that when the brush wheel 11 contacts with the shoe to be tested, contact resistance is inevitably generated between the brush wheel 11 and the shoe to be tested, so that the load of the motor 13 is increased; meanwhile, since the moving speed of the moving device 12 is kept constant, that is, the output rotating speed of the motor 13 is always constant, increasing the load of the motor 13 inevitably leads to an increase in the operating current thereof. In other words, when the load of the motor 13 increases, the motor 13 increases its output power by increasing the operation current, so as to ensure that the mobile device 12 can always move at a constant speed. The shoe size detection method of the present invention is also based on the principle that the brush wheel 11 generates contact resistance when contacting with the shoe to be detected, thereby causing the operation current of the motor 13 for driving the moving device 12 to change, so as to obtain the contact state of the brush wheel 11 and the shoe to be detected, thereby measuring the size of the shoe to be detected.
Here, it should be noted that the two steps of step S101 and step S102 may be executed simultaneously; step S101 may be executed first, and then step S102 may be executed, that is, the execution order of the two steps may be set by a technician. In addition, although the operation current of the motor 13 is obtained in real time in step S102 of the preferred embodiment, it is obvious that the operation current of the motor 13 may be obtained at intervals of a predetermined time, and the length of the predetermined time may be set by a technician.
With continued reference to fig. 2, the method determines the position of the shoe to be measured by determining whether the running current of the motor 13 is suddenly increased relative to the predetermined current in step S103, so as to calculate the size of the shoe to be measured in the following step. It can be understood that since the control device of the shoe washing machine 1 can easily obtain the operation current of the motor 13, and the operation current of the motor 13 can be quickly adaptively changed as the load of the motor 13 is changed, thereby improving the output efficiency of the motor 13. The operation current of the motor 13 is easy to obtain, so that the operation steps of the method can be simplified by taking the operation current as basic data; since the running current of the motor 13 can change rapidly according to the load condition, the shoe washing machine 1 can timely acquire the change condition of the contact state of the brush wheel 11 and the shoe to be tested, so that the shoe washing machine 1 can more accurately and rapidly judge the contact state of the brush wheel 11 and the shoe to be tested, and more accurate size information can be calculated in the following steps. It should be noted that the sudden increase of the operating current with respect to the predetermined current in the preferred embodiment means that the operating current suddenly increases by a predetermined amount with respect to the predetermined current at a certain time, and specifically, the selection of the predetermined amount is related to the model of the motor 13, and can be set by a technician according to the actual use condition.
It is understood that the predetermined current in the preferred embodiment is the operation current of the motor 13 when the mobile device 12 and the shoe to be tested are in a non-contact state. In short, if the mobile device 12 makes contact with the shoe to be tested during the moving process, the mobile device 12 will inevitably receive the contact resistance caused by the shoe to be tested, and at this time, the running current of the motor 13 will inevitably increase suddenly relative to the predetermined current. Therefore, if the running current of the motor 13 suddenly increases with respect to the predetermined current, it indicates that the brush wheel 11 has come into contact with the shoe to be tested.
Further, if the judgment result in the step S103 is that the running current of the motor 13 suddenly increases relative to the predetermined current, it indicates that the brush wheel 11 has contacted the shoe to be tested; at this time, step S104 is executed to record the time point as a first time point, i.e. the time point when the mobile device 12 starts to contact with the shoe to be measured, so as to calculate the size of the shoe to be measured by using the first time point in the following steps. In addition, if the operation current of the motor 13 is not suddenly increased relative to the predetermined current as a result of the determination in step S103, it indicates that the brush wheel 11 has not been in contact with the shoe to be tested; at this time, step S102 is executed again to determine again the contact state between the mobile device 12 and the shoe to be tested.
With continued reference to fig. 2, after the first time point is obtained in step S104, step S105 is executed to obtain the running current of the motor 13 for driving the mobile device 12 in real time. Further, in step S106, it is determined whether the operating current of the motor 13 is suddenly decreased to a predetermined current. It can be understood that, since it has been determined in step S103 that the brush wheel 11 is in a contact state with the shoe to be tested; therefore, the brush wheel 11 will be in contact with the shoe to be tested for a period of time after the first point in time.
It will be understood by those skilled in the art that the moving device 12 is always subjected to contact resistance as long as the brush wheel 11 is in contact with the shoe to be tested, i.e. the running current of the motor 13 is always maintained to be greater than the predetermined current. In other words, when the running current of the motor 13 is suddenly reduced to a predetermined current, the brush wheel 11 is necessarily in a state of being out of contact with the shoe to be tested, and at this time, the brush wheel 11 is already in one-time contact with the shoe to be tested along the length direction. It should be noted that, although the operation current of the motor 13 is obtained in real time in step S105 of the preferred embodiment, it is obvious that the operation current of the motor 13 may also be obtained after a predetermined time, and the length of the predetermined time may be set by a technician.
Further, if the judgment result in the step S106 is that the running current of the motor 13 is suddenly reduced to the predetermined current, it indicates that the brush wheel 11 is in a state of being out of contact with the shoe to be tested; at this time, step S107 is executed to record the time point as a second time point, namely, the time point when the mobile device 12 finishes contacting the shoe to be tested, so as to calculate the total time of contacting the brush wheel 11 with the shoe to be tested in the following steps, thereby calculating the size of the shoe to be tested. In addition, if the operation current of the motor 13 is not suddenly reduced to the predetermined current as a result of the determination in step S106, it indicates that the brush wheel 11 is still in a state of contacting with the shoe to be tested; at this time, step S105 is executed again to determine again the contact state between the mobile device 12 and the shoe to be tested. It should be noted that the sudden drop of the operating current to the predetermined current in the preferred embodiment means that the operating current suddenly drops to a value near the predetermined current at a certain time, specifically, the fluctuation range is related to the model of the motor 13, and the technician can set the range according to the actual use condition.
With reference to fig. 2, after the second time point is obtained in step S107, step S108 is executed to calculate a difference between the second time point and the first time point, so as to obtain a total time of the brush wheel 11 contacting the shoe to be tested. Then, the rotation speed of the motor 13 is obtained in step S109, and the moving speed of the moving device 12 is calculated so as to calculate the total distance that the moving device 12 moves during the period that the brush wheel 11 is in contact with the shoe to be tested. Here, it should be noted that although the rotation speed of the motor 13 is obtained in step S108 in the preferred embodiment, it is obvious that the rotation speed of the motor 13 may also be obtained in the previous step; meanwhile, if the output rotation speed of the motor 13 is changed in real time, the rotation speed of the motor 13 needs to be measured in real time in order to accurately calculate the moving distance of the mobile device 12.
Further, in step S110, the total distance that the mobile device 12 moves during the period when the brush wheel 11 is in contact with the shoe to be tested is calculated according to the time difference between the second time point and the first time point and the moving speed of the mobile device 12; it will be appreciated that the total distance moved by the moving device 12 is equal to the length of the shoe to be measured, and the size of the shoe to be measured can be obtained. Since the operation parameters of the motor 13 are very easily obtained and the relative error of the operation parameters is very small, the shoe washing machine can measure the size of the shoe to be measured by only accurately obtaining the contact time between the brush wheel 11 and the shoe to be measured. The mode of measuring the size of the shoe to be measured by combining the operation parameters of the motor is beneficial to quickly acquiring data, and the acquired data are accurate and effective so as to quickly and accurately measure the size of the shoe to be washed.
Finally, it should be noted that the above examples are all preferred embodiments of the present invention, and should not be construed as limiting the scope of the present invention. When the present invention is actually used, a part of the steps may be added or deleted as needed or the order between the different steps may be changed by those skilled in the art. Such variations are not to be regarded as a departure from the spirit and scope of the invention.
So far, the preferred embodiments of the present invention have been described in conjunction with the accompanying drawings, but it is apparent to those skilled in the art that the scope of the present invention is not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
