[0013] The washing equipment includes an equipment housing, a washing water unit, a foam cleaning unit and a hot air unit. The equipment housing is arranged on the upper part of the washing platform. The washing water unit includes a washing water terminal and a washing water pump. One end of the washing water pump is connected to the water source, and the other end is connected to the washing water terminal. The foam cleaning unit includes a foam terminal, a foaming tank and a foaming pump. The foaming tank is installed at the lower part of the wash basin body. The foaming tank contains foaming liquid.

[0014] The above-mentioned sewage collecting structure includes a sewage collecting bin and a separation plate. The sewage collecting bin is a bin body with an opening at the upper end. The sewage collecting bin is located at the rear end of the washing platform. The step body is located between the washing platform and the sewage collecting bin. The separation plate is located in the sewage collecting bin. A number of through holes are provided on the separation plate, and debris larger than the diameter of the through holes remain on the separation plate. Debris and water smaller than the diameter of the through holes enter the bottom of the sewage collecting bin through the separation plate. The bottom of the sewage collecting bin is connected to the sewer pipe.

[0015] The method for using the above-mentioned automatic cleaning washbasin includes the following steps: when the magnetic scraper is placed obliquely at any position on the washing platform, the control device controls the driving unit of the magnetic drive device to operate, and the driving unit drives the bottom magnetic plate to move backward to the rear end of the stroke, and then returns. During this process, the magnetic scraper changes from being inclined to being parallel to the width direction of the washing platform, and returns to the front end of the washing platform with the bottom magnetic plate.

[0016] The method of using the automatic cleaning wash basin includes the following steps:

[0017] Step 1: When the magnetic induction unit is properly connected to the bottom magnetic plate and the washing device is not started, the magnetic drive device does not operate;

[0018] Step 2: When the magnetic induction unit is magnetically connected to the bottom magnetic plate normally and the washing device is started for a preset time, the control device controls the driving unit of the magnetic driving device to operate, and the driving unit drives the bottom magnetic plate and the magnetic scraper to move backward to the rear end of the stroke, and then returns. During the backward movement of the magnetic scraper, the magnetic scraper scrapes the upper surface of the washing platform. When the magnetic scraper moves backward to the rear end of the stroke, the magnetic scraper pushes the sewage and debris on the upper surface of the washing platform into the sewage collecting structure. At the same time, the magnetic scraper is located at the step body at the rear end of the washing platform, and the control device controls the flushing nozzle to spray water to flush the magnetic scraper;

[0019] Step 3. When the magnetic scraper is picked up, the magnetic connection between the magnetic induction unit and the bottom magnetic plate is interrupted, and the magnetic induction unit sends a signal to the control device. The control device controls the driving unit to drive the bottom magnetic plate to move backward to the rear end of the stroke, and then returns, and repeats this action at a preset time interval until the magnetic connection between the magnetic induction unit and the bottom magnetic plate is restored to normal; when the magnetic scraper is put back to any position on the washing platform, the length direction of the magnetic scraper is not parallel to the width direction of the washing platform, that is, the magnetic scraper is placed at an angle, and when the driving unit drives the bottom magnetic plate to pass under the magnetic scraper, it will inevitably approach the magnetic scraper first. The scraper magnetic point at one end of the scraper plate establishes a magnetic connection with the bottom magnetic plate and one end of the magnetic scraper plate. The magnetic scraper plate moves with the bottom magnetic plate, and the other end of the magnetic scraper plate will rotate or touch the baffle plate at the rear end of the washing platform or touch the enclosure at the front end of the washing platform due to friction, and then rotate to be parallel to the width direction of the washing platform. At this time, the scraper magnetic point at the other end of the magnetic scraper plate also establishes a magnetic connection with the bottom magnetic plate, and the magnetic connection between the magnetic induction unit and the bottom magnetic plate returns to normal. When the bottom magnetic plate returns to the front end of the stroke, the magnetic scraper plate follows and returns to the front end of the washing platform.

[0020] The beneficial effects of the present invention are:

[0021] 1. The present invention provides a wash basin with automatic cleaning function. A magnetic scraper with a scraper magnetic attraction point is arranged on the upper surface of the wash platform, and a bottom magnetic plate is arranged on the lower surface of the wash platform. The bottom magnetic plate is connected to the drive unit by transmission. Through the principle of mutual attraction of magnets, the bottom magnetic plate drives the magnetic scraper to move on the upper surface of the wash platform, and pushes the sewage and debris on the upper surface of the wash platform into the sewage collection structure to achieve self-cleaning of the wash platform. This device does not need to open gaps on the surface and side of the wash platform to install the transmission structure, so there is no problem of sewage easily entering the gap, causing water to enter the internal structure of the wash basin. At the same time, when cleaning the magnetic scraper, it only needs to be removed from the wash platform, cleaned, and then put back on the wash platform. It is very convenient to disassemble and assemble.

[0022] 2. The magnetic scraper of the present invention is extremely convenient to return to its original position after being removed for cleaning. The user can place the magnetic scraper at any position on the washing platform at any inclination angle, and the magnetic scraper will automatically return to the front end position of the washing platform. The specific method is as follows: when placed at any position on the washing platform at any inclination angle, the driving unit drives the bottom magnetic suction plate to pass under the magnetic scraper, and it will inevitably approach the scraper magnetic suction point at one end of the magnetic scraper first, and the bottom magnetic suction plate establishes a magnetic connection with one end of the magnetic scraper, and the magnetic scraper moves with the bottom magnetic suction plate, and the other end of the magnetic scraper will rotate or touch the baffle at the rear end of the washing platform or the enclosure at the front end of the washing platform due to friction, and then rotate to be parallel to the width direction of the washing platform. At this time, the scraper magnetic suction point at the other end of the magnetic scraper also establishes a magnetic connection with the bottom magnetic suction plate, and the magnetic connection between the magnetic induction unit and the bottom magnetic suction plate returns to normal. When the bottom magnetic suction plate returns to the front end of the stroke, the magnetic scraper follows and returns to the front end of the washing platform.

[0023] 3. The present invention sets a concave step body at the connection between the washing platform and the sewage collecting bin. The step body allows the flexible scraper strip that was originally bent by the washing platform to straighten freely at the step body, and the lower end of the flexible scraper strip is completely exposed. Nozzles are set on both sides of the step body. The nozzles can clean the lower end of the magnetic scraper plate by spraying water, and also rinse the step body, and flush the debris on the step body into the sewage collecting bin. Since the bottom of the magnetic scraper plate is the position most likely to hide dirt and grime, by setting the nozzle, the lower surface of the magnetic scraper plate can be effectively cleaned, and the frequency of manual cleaning of the magnetic scraper plate by staff can be significantly reduced. Since the flexible scraper strip is in close contact with the washing platform, it is generally difficult to clean the flexible scraper strip by flushing with water. The present invention sets the step body to fully expose the flexible scraper strip, thereby realizing the cleaning of the flexible scraper strip, ensuring that there is no dead angle in the cleaning of the lower end of the magnetic scraper plate.

[0024] 4. The present invention is respectively provided with a left guide bracket, a right guide bracket and a middle guide bracket, wherein the middle guide bracket can prevent the mounting plate from shaking left and right, and the left guide bracket and the right guide bracket can prevent the bottom magnetic suction plate from shaking left and right. Then the left guide bracket, the right guide bracket and the middle guide bracket are connected together, so that the entire magnetic drive device is firmly connected and runs smoothly, thereby effectively improving the operating stability of the entire set of equipment.

The lower end of the adjusting rod 93 is hinged at the middle of the baffle plate 91. The adjusting motor 92 can pull the baffle plate 91 through the adjusting rod 93 to make the baffle plate 91 rotate around its own upper end, thereby changing the size of the gap between the baffle plate 91 and the upper surface of the washing platform 2, so that the gap between the baffle plate 91 and the upper surface of the washing platform 2 is smaller than the height of the magnetic scraper 4.

[0052] The present invention also provides a method for using the automatic cleaning wash basin, comprising the following steps:

[0053] Step 1: When the magnetic induction unit is magnetically connected to the bottom magnetic attraction plate 51 normally and the washing device 3 is not started, the magnetic drive device 5 does not operate;

[0054] Step 2: When someone uses the washing equipment 3 and brings his hand close to the infrared sensor 37, the control device receives the information sent by the infrared sensor 37 and controls the flushing water pump or the foaming pump 33 or the hot air blower 35 to work. The corresponding washing water terminal 31 will flow out clean water, the foam terminal 32 will flow out cleaning foam, and the hot air terminal 34 will emit hot air. When the hand leaves the infrared sensor 375-10 seconds later, the control device controls the driving unit of the magnetic drive device 5 to operate. The driving unit drives the bottom magnetic suction plate 51 and the magnetic suction scraper 4 to move backward to the rear end of the stroke, and then returns. Then the hot air blower 35 works for a few seconds to assist in drying the washing platform 2. During the backward movement of the magnetic suction scraper 4, the magnetic suction scraper 4 scrapes the upper surface of the washing platform 2. When the magnetic suction scraper 4 moves backward to the rear end of the stroke, the magnetic suction scraper 4 pushes the sewage and debris on the upper surface of the washing platform 2 into the sewage collecting structure 6;

[0055] Step 3, when the magnetic scraper 4 is picked up, the magnetic connection between the magnetic induction unit and the bottom magnetic plate 51 is interrupted, and the magnetic induction unit sends a signal to the control device. The control device controls the driving unit of the magnetic drive device 5 to operate every 30 seconds to 1 minute, and the driving unit drives the bottom magnetic plate 51 to move backward to the rear end of the stroke, and then returns; when the magnetic scraper 4 is put back to any position on the washing platform 2, the length direction of the magnetic scraper 4 is not parallel to the width direction of the washing platform 2, that is, the magnetic scraper 4 is placed at an angle, and the driving unit When the bottom magnetic plate 51 is driven by the element to pass under the magnetic scraper 4, it will inevitably approach the scraper magnetic point 41 at one end of the magnetic scraper 4 first, and the bottom magnetic plate 51 will establish a magnetic connection with one end of the magnetic scraper 4, and the magnetic scraper 4 will move with the bottom magnetic plate 51. At this time, the magnetic scraper 4 has two states. If the inclination of the magnetic scraper 4 is small, the other end of the magnetic scraper 4 will rotate due to the friction force. If the inclination of the magnetic scraper 4 is large, the magnetic scraper 4 will not rotate but move with the bottom magnetic plate 51. The bottom magnetic plate 51 also has two movement directions, namely forward and backward. When the bottom magnetic plate 51 moves forward, the other end of the magnetic scraper 4 will touch the enclosure 11 at the front end of the washing platform 2 and rotate. When the bottom magnetic plate 51 moves backward, the other end of the magnetic scraper 4 will touch the baffle 91 at the rear end of the washing platform 2 and rotate. Therefore, no matter which one, the magnetic scraper 4 will rotate to be parallel to the width direction of the washing platform 2. At this time, the scraper magnetic point 41 at the other end of the magnetic scraper 4 also establishes a magnetic connection with the bottom magnetic plate 51, and the magnetic connection between the magnetic induction unit and the bottom magnetic plate 51 returns to normal. When the bottom magnetic plate 51 returns to the front end of the stroke, the magnetic scraper 4 follows and returns to the front end of the washing platform 2.

[0056] Step 4. At regular intervals, for example, after the magnetic scraper 4 scrapes the upper surface of the washing platform 2 5-10 times, when the magnetic scraper 4 moves to the step body 83 at the rear end of the washing platform 2, the control device controls the solenoid valve installed on the flushing water pipe 81 to make the flushing nozzle 82 spray water to flush the magnetic scraper 4. The flushing time is 5-10 seconds, and then the magnetic scraper 4 moves forward and returns.

[0057] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should be regarded as the protection scope of the present invention.
