The present invention will be further described with reference to the following examples.
The embodiment is as follows:
the invention provides a cleaning machine with a reverse function, which mainly aims at the structural design and the method steps of self-cleaning of a rolling brush 30 after the cleaning machine finishes cleaning operation and is matched with a base 10 for use:
1. in the structural design of the cleaning machine: referring to fig. 1, 3 and 4;
the main structure of the device comprises a liquid supply device 20 for conveying clean liquid, wherein the liquid supply device 20 comprises a clear water barrel for storing the clean liquid, a liquid outlet 21 is reserved on the upper side of a rolling brush 30, the clear water barrel and the liquid outlet 21 are connected and communicated through a pipeline, and the electromagnetic valve is matched for controlling the on-off of the conveying of the clean liquid.
And a rolling brush 30 and a rolling brush motor 31 for driving the rolling brush 30 to rotate, wherein the rolling brush motor 31 in the present application can drive the rolling brush 30 to rotate forward and backward.
A wiper strip 40 for wiping off liquid and dirt on the roller brush 30, the wiper strip 40 functioning to: in the self-cleaning process, after the cleaning liquid is soaked on the roller brush 30, the roller brush 30 rotates to contact with the scraping strips 40, and the sewage and dirt on the cleaning liquid are scraped off by the stainless steel scraping strips 40 and then sucked away, so that the process of completely removing the sewage and spraying clean water is realized similarly to the process of completely removing the sewage and spraying clean water every time the roller brush 30 rotates for one circle.
A suction device 50 driven by a main motor for sucking the liquid and dirt scraped off by the roller brush 30 into a suction pipe, wherein the sucked liquid and dirt are stored in the sewage bucket;
the electromagnetic valve, the rolling brush motor 31 and the host motor of the liquid supply device 20 are connected to the output end of the controller; the controller can obtain a starting signal and start a forward rotation cleaning mode; acquiring a switching signal and starting a reverse cleaning mode.
It is noted that the cleaning liquid referred to in this application may be clear water, electrolyzed water or a mixture of both with a cleaning agent. The starting signal can be a physical switch button arranged on the washing machine, a triggered quantity signal pressed by a user, or a wirelessly received trigger signal.
Among them, in the present embodiment, it is preferable to realize the forward and reverse rotation design of the rolling brush motor 31 for driving the rolling brush 30: a driving circuit is connected between the rolling brush motor 31 and the controller, the driving circuit mainly comprises an H-bridge circuit consisting of a first switching circuit, a second switching circuit, a third switching circuit and a fourth switching circuit, and the brush direct current is controlled by a silicon controlled rectifier analog circuit to be reversed through a carbon brush, so that the forward and reverse rotation switching of the motor is realized. That is, when the first switch circuit and the fourth switch circuit are turned off and the second switch circuit and the third switch circuit are turned on at the same time, the motor of the rolling brush 30 rotates in the forward direction; the first switch circuit and the fourth switch circuit are simultaneously conducted, and when the second switch circuit and the third switch circuit are simultaneously closed, the rolling brush motor 31 rotates reversely; the whole control is simple to realize.
In order to ensure that the suction device 50 sucks the sewage and dirt squeezed out by the scraping bar 40 in the process of the rolling brush 30 reversing, the appearance structure of the scraping bar 40 is optimally designed, the scraping bar 40 is made into a hollow area 41 close to the outer end part thereof, the upper side of the scraping bar 40 is also communicated with the liquid suction pipeline of the suction device 50 through the hollow area 41, and the sewage and dirt attached to the upper side of the scraping bar 40 can be squeezed and sucked when the rolling brush 30 reverses. Meanwhile, in order to improve the supporting strength of the bar 40, a plurality of raised ribs are fixed through the upper portion thereof.
The cleaning machine with the improved structure is shown in figure 2: the invention provides a self-cleaning method of a cleaning machine with a reverse function, which comprises the following steps:
the controller acquires a starting signal, starts a forward rotation cleaning mode, starts the rolling brush motor 31, and drives the rolling brush 30 to rotate forward for cleaning;
the controller acquires a switching signal, stops the forward rotation cleaning mode, starts the reverse rotation cleaning mode, drives the rolling brush motor 31 to rotate reversely, and cleans the rolling brush 30 in a reverse rotation mode;
wherein, the positive rotation cleaning mode and the reverse rotation cleaning mode comprise the following substeps:
starting the liquid supply device 20, and conveying clean liquid to wet the roller brush 30;
starting a rolling brush motor 31 to rotate a rolling brush 30;
starting a main machine motor, and sucking the liquid and dirt scraped from the rolling brush 30 to a liquid suction pipeline;
wherein, the rotating speed of the rolling brush motor 31 is adjusted by change in the positive rotation or the negative rotation.
Of course, when the start signal is obtained, it is assumed that the cleaning machine is placed on the base 10 in a reset manner, and the signal manner for knowing that the cleaning machine is correctly placed on the base 10 may be to obtain a signal that the cleaning machine is connected to an external power supply, or to obtain whether the cleaning machine is on the base 10 by reserving a micro switch or a proximity sensor on the base 10. A wash bowl 11 having an inner diameter larger than an outer diameter of the drum brush 30 is formed at a front side of the base 10, and the drum brush 30 is rotatable in the wash bowl 11.
Wherein, the process design for controlling the forward rotation cleaning mode to be switched to the reverse rotation cleaning mode is as follows: the detection module sends a switching signal to the controller to control the forward rotation cleaning mode to be converted into the reverse rotation cleaning mode;
in this embodiment, the switching signal is preferably a detection signal for detecting that the forward rotation cleaning mode reaches a preset time, and the detection module is a timer module, and the detection signal is used for comparing the operation time of the forward rotation cleaning mode with the preset time, and stopping and switching to the reverse rotation cleaning mode when the operation time of the forward rotation cleaning mode reaches the preset value. For example, the forward rotation cleaning mode designed by the product has an operation time of 45s, and after the preset time is reached, the controller controls the rolling brush motor 31 to stop and then reversely rotate.
The switching signal may also be other signals, such as: by detecting that the liquid level in the water tank is higher than the preset liquid level, the detection module adopts the liquid level sensor 60, and by installing the liquid level sensor 60 in the clear water barrel, whether the corotation cleaning mode reaches the cleaning standard is judged by detecting the liquid consumption used in the corotation cleaning mode.
Of course: in order to improve the self-cleaning effect of the rolling brush 30 under different cleaning working environments, a dynamic compensation mechanism is arranged inside the controller, for example: in 20-inch household cleaning operation, because the dirt on the ground is difficult to remove, a 'powerful cleaning' mode is adopted for 10 minutes, and the standard cleaning mode is adopted for the other 10 minutes; this is different from the degree of soiling of the rolling brush 30 in the standard cleaning mode for 20 minutes, and the rolling brush 30 in the "power cleaning" mode for 10 minutes is generally more soiled, so by providing dynamic compensation values for both the preset time and the preset liquid level, which are proportional to the operating time of the cleaning machine in the power cleaning mode, it is ensured that the self-cleaning time or more cleaning liquid for the rolling brush 30 in each mode is increased in the more soiled state of the rolling brush 30.
Specifically, in the step of delivering clean liquid to wet the roller brush 30, the liquid outlet 21 may be designed on the body housing above the side of the roller brush 30, and the pump body is matched with the electromagnetic valve to realize spraying; the liquid outlet 21 can also be designed at the square of the rolling brush 30, and naturally drops or extrudes and drops on the rolling brush 30 by the gravity of the liquid.
Further specifically, in the forward rotation cleaning mode, after the step of activating the liquid supply device 20, referring to fig. 5 to 8:
after a certain time delay, in this embodiment, after a time delay of 5s, the rolling brush motor 31 is started, and the rolling brush motor 31 rotates at a low speed and operates synchronously with the liquid supply device 20 for 15s;
then, when the main motor is turned on, the liquid supply device 20 is turned off, and the roller brush motor 31 is rotated at a high speed and is operated in synchronization with the main motor for 15s.
According to the design of the method, the rolling brush motor 31 is started after the 5s delay, so that the cleaning liquid can fully soak the rolling brush 30, the dirt in the rolling brush can be adsorbed and taken out, and meanwhile, the cleaning liquid can not be completely thrown out on the rolling brush 30 due to high-speed centrifugal force by matching with the early-stage low-speed rotation of the rolling brush motor 31, so that the cleaning time of the cleaning liquid on the fiber threads of the rolling brush 30 is prolonged, and the cleaning effect is improved. And the later period is used for spin-drying the cleaned sewage through the synchronous operation of the high-speed rotation of the rolling brush motor 31 and the main machine motor for 15s so as to prepare for entering a reverse rotation cleaning mode.
Then, in the reverse cleaning mode, after the step of activating the liquid supply device 20,
after a certain time delay, in this embodiment, also after a time delay of 5s, the rolling brush motor 31 and the host motor 15s are synchronously started, and at this time, the rolling brush motor 31 rotates at a low speed;
after a certain time of continuous synchronization, which is 5s in this embodiment, the liquid supply device 20 is turned off. The rolling brush motor 31 and the main machine motor continue to keep the running state for 15s, and after the liquid supply device 20 is closed, the rolling brush motor 31 rotates at a high speed.
The design of the method is to continue the treatment of the positive rotating cleaning mode, firstly, the time is delayed by 5s, and the cleaning liquid is still allowed to fully soak the rolling brush 30 so as to realize deep cleaning; meanwhile, the three parts are synchronously opened, cleaning liquid is continuously conveyed to be matched with the rolling brush 30 to rotate reversely, so that the rolling brush 30 is further cleaned, meanwhile, hair and other winding objects and dirt wrapped between the fiber yarns are removed, and the synchronously opened main machine motor can suck and take away the dirt such as sewage and hair in time; and then in a high speed rotation of 15s for spinning the liquid on the roll brush 30, keeping the roll brush 30 as dry as possible.
In the self-cleaning process of the rolling brush 30, the forward rotation cleaning mode and the reverse rotation cleaning mode are combined, compared with the cleaning mode that the rolling brush 30 rotates in a single direction in the prior art, the reverse rotation cleaning method can effectively remove the winding objects, meanwhile, the fiber yarns of the bending-over rolling brush 30 are pushed forward and restored in the reverse direction, dirt among the fiber yarns can be better removed, and the self-cleaning effect of the rolling brush 30 is greatly improved.
The above examples are only intended to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and the modifications or the substitutions do not depart from the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
