Description
Technical Field
The present invention relates to a cleaning machine and a control method of the cleaning machine.
Background
The main machine switch and the spray gun switch of the existing cleaning machine are independent. When the spray gun is closed, although the spray gun cannot spray water, the main machine is still in a normal working state at the moment, namely: the plunger of the high pressure pump is still constantly reciprocating. The water pressure in the cylinder wall of the high-pressure pump gradually rises due to the fact that high-pressure water cannot be sprayed out of the spray gun. When the pressure acting on the pressure relief valve is larger than the upper limit of the pressure relief valve, the pressure relief valve is opened to form internal circulation between the pressure relief channel and the high-pressure pump, so that the pressure in the cylinder wall of the high-pressure pump returns to normal, and the motor driving the high-pressure pump to operate is in an idling state, and the rotation speed of the motor is usually 4400 RPM. If the spray gun is opened again, the motor is equivalently suddenly loaded, and the motor drives the high-pressure pump to operate so as to convert the low-pressure low-speed water into the high-pressure low-speed water which is conveyed to the spray gun through the high-pressure pipeline. The high-pressure low-speed water flow needs to be accelerated to be converted into low-pressure high-speed water jet through the spray gun, and the motor needs to do work immediately at the moment. The motor is converted from no load to load such that its speed drops sharply from 4400RPM in the no load condition to 2700RPM in the load condition. Accordingly, the current through the motor is also increased instantaneously from a few amperes in the no-load state to twenty-few amperes, and then returns to about 15A in the normal operating state. The large current generated in the motor is caused by the gun being turned off without stopping. When the motor is suddenly changed from no-load to load, the rotating speed is suddenly reduced, so that the slip ratio is increased, the induced electromotive force generated by the rotor cutting magnetic field is increased, and the rotor current is increased. Since the magnetic field generated by the rotor current has a weakening effect on the stator, the stator must increase the coil current in order to maintain its magnetic flux, resulting in an increase in the current through the motor. This sudden increase in current causes the motor to heat more quickly and more, and causes the water temperature to rise and the water pressure to rise. When the water temperature and the water pressure reach threshold values, the temperature control valve and the pressure release valve arranged in the high-pressure pump are started to release heat and water pressure. In actual use, the cleaning machine is often in a state that the gun is closed and is not stopped, so that the temperature control valve and the pressure release valve are seriously abraded, and the service life of the cleaning machine is seriously influenced.
In view of the above problems, there is a need to provide a new washing machine to solve the above problems.

The pump head assembly 11 includes a high pressure pump 111 and a motor 112 for driving the high pressure pump 111. The input end of the high-pressure pump 111 is connected with the liquid storage tank 30 to pump the liquid in the liquid storage tank 30; the output of the high pressure pump 111 is connected to the spray gun assembly 20 to output a high pressure low velocity stream of liquid to the spray gun assembly 20. In the present embodiment, the motor 112 is an electric motor, but in other embodiments, the motor 112 may also be a gasoline engine. When the motor 112 is a gasoline engine, a self-starting system is further configured to facilitate the control component 12 to control the start or stop of the gasoline engine through the self-starting system. The control assembly 12 comprises a control unit 121, a drive circuit 122 for driving the motor 112 and a power supply control circuit 123 for controlling the first power supply 14 to supply power to the pump head assembly 11. The control unit 121 may be a central processing unit, a single chip, or the like. The first communication unit 13 is connected to the control unit 121 to transmit the received information to the control unit 121 or send an instruction of the control unit 121. The first power source 14 may be a battery pack, mains electricity or the like, for powering the pump head assembly 11, the control assembly 12 and the first communication unit 13. Preferably, the control component 12 and the first communication unit 13 are integrated on a main board 40, so that the assembly difficulty of an operator can be reduced, and the assembly efficiency can be improved. The housing 15 is configured to house the pump head assembly 11, the control assembly 12, and the first communication unit 13. When the first power source 14 is a battery pack, the housing 15 may be further provided with a battery compartment for accommodating the battery pack.
Referring to fig. 1, the spray gun assembly 20 includes a spray gun 21, a pipe 22, a second communication unit 23 disposed on the spray gun 21, and a second power supply (not shown) for supplying power to the second communication unit 23. The spray gun 21 is connected to the output end of the high-pressure pump 111 through the pipe 22 so as to spray the high-pressure low-speed flow output by the high-pressure pump 111 at an extremely high speed. The second communication unit 23 communicates with the first communication unit 13 to transmit information on the opening or closing of the spray gun 21 to the control assembly 12. When the spray gun 21 is opened, the second communication unit 23 communicates directly or indirectly with the first communication unit 13, so that the control assembly 12 controls the operation of the pump head assembly 11; when the spray gun 21 is switched off, the second communication unit 23 communicates directly or indirectly with the first communication unit 13, so that the control assembly 12 controls the pump head assembly 11 to stop working. Because the user closes at every turn behind the spray gun 21, pump head assembly 11 also can the synchronous stop work, consequently pressure in the high-pressure pump 111 is in normal working range all the time, can not appear current cleaning machine because of the shut down problem that the high-pressure pump internal pressure that causes increases gradually of not shutting down the rifle to the relief valve that sets up on the current cleaning machine can be cancelled, the structure of high-pressure pump is simplified, the manufacturing cost of cleaning machine has effectively been reduced. In addition, because the motor 112 of the pump head assembly 11 needs to be restarted each time the spray gun 21 is turned on by a user, the motor 112 is in the process of accelerating from zero to a normal rotating speed, and the phenomenon of sudden load change does not occur, the current passing through the motor 112 cannot be increased instantly, and the problem of instant large current caused by restarting the existing cleaning machine cannot occur. Because the motor 112 does not generate a transient large current, the motor 112 does not generate heat abnormally due to the transient large current, so that the temperature of the cleaning liquid in the high-pressure pump 111 is not increased; in addition, because the spray gun 21 and the pump head assembly 11 are opened or closed simultaneously, the high-pressure pump 111 does not need to make the cleaning liquid circulate inside through a pressure relief valve and a circulation pipeline, so that the problem of temperature rise caused by repeated internal circulation of the cleaning liquid can be effectively avoided, a temperature control valve arranged on the existing cleaning machine can be further cancelled, the structure of the high-pressure pump is simplified, and the production cost of the cleaning machine is effectively reduced. In addition, the temperature control valve and the pressure release valve are eliminated, so that the problem that the existing cleaning machine is invalid due to the fact that the pressure release valve and the temperature control valve are seriously abraded is effectively solved.

The first communication unit 13 and the second communication unit 23 may be a bluetooth communication module, a WIFI module, an infrared communication module, a ZigBee communication module, a GPRS communication module, or the like. Preferably, the spray gun assembly 20 is further provided with an indication unit (not shown) to indicate whether the first and second communication units 13 and 23 are successfully connected and can communicate normally, so that a user can quickly determine whether the washing machine 100 can be used normally. In this embodiment, the second communication unit 23 is powered by a second power source disposed on the spray gun 21, which may be a small battery pack, a rechargeable battery, or the like. It is understood that in other embodiments, the second communication unit 23 may also be powered by the first power supply 14. At this time, the spray gun assembly 20 needs to be provided with a power supply line connecting the second communication unit 23 and the first power supply 14. In order to avoid the cleaning machine 100 becoming cluttered due to the additional provision of power supply lines, the power supply lines can be fastened to the pipe 22 in the direction of extension of the pipe 22. In other embodiments, the first communication unit 13 and the second communication unit 23 may also communicate through wired signals. At this time, the spray gun assembly 20 needs to be provided with a communication line connecting the second communication unit 23 and the first communication unit 13. In order to avoid the confusion of the washing machine 100 due to the additionally provided communication line, the communication line may be fixed to the duct 22 along the extending direction of the duct 22.
When actually using the washing machine, the user sometimes needs to temporarily shut off the spray gun 21 for a while, for example: temporarily shutting the gun for 1-3 seconds in places where pedestrians need to be avoided and cleaning is not needed. In this case, it is also inappropriate to choose to shut off the pump head assembly 11. Therefore, the washing machine 100 is preferably further provided with a delay unit (not shown). In the present embodiment, the delay unit is provided on the spray gun 21. It is understood that the delay unit may be disposed on the host 10. When the spray gun 21 is closed, the delay unit operates to delay the pump head assembly 11 for a predetermined time before closing. When the spray gun 21 is turned on again within a preset time, the pump head assembly 11 is controlled to continue operating. Preferably, when the spray gun 21 is closed, the delay unit controls the second communication unit 23 to communicate with the first communication unit 13 after delaying the preset time. It will of course be appreciated that in other embodiments the delay unit may also be arranged to: when the spray gun 21 is closed, the second communication unit 23 communicates with the first communication unit 13 to send the delay instruction sent by the delay unit to the control assembly 12, and the control assembly 12 controls the pump head assembly 11 to stop working after delaying the preset time.
Referring to fig. 1, the liquid storage tank 30 is used for storing a cleaning liquid and is connected to an input end of the high pressure pump 111 through a connecting pipe 31, so that the pump head assembly 11 can pump the cleaning liquid in the liquid storage tank 30. Preferably, a filter 311 is further disposed in the connection pipe 31 to filter out impurities in the cleaning solution, so as to prevent the impurities from damaging the high-pressure pump 111 and the spray gun 21. In the present embodiment, the liquid storage tank 30 and the housing 15 are separately provided, but in other embodiments, the liquid storage tank 30 and the housing 15 may also be integrally provided.
When the washing machine 100 of the present invention is used, first, the second communication unit 23 and the whole machine 10 are powered on, and whether the first communication unit 13 and the second communication unit 23 are normally connected and can normally communicate is checked. Then, the spray gun 21 is turned on, at this time, the second communication unit 23 sends an opening instruction to the first communication unit 13, the first communication unit 13 transmits a corresponding instruction to the control unit 121, the control unit 121 controls the power control circuit 123 to operate so that the first power supply 14 supplies power to the motor 112, and then controls the driving circuit 122 to operate so as to drive the motor 112 to operate. When the spray gun 21 is turned off, the second communication unit 23 sends a turn-off command to the first communication unit 13, the first communication unit 13 transmits a corresponding turn-off command to the control unit 121, and the control unit 121 controls the driving circuit 122 to stop working, so that the first power supply 14 stops supplying power to the motor 112, and then controls the power supply control circuit 123 to stop working.
Compared with the prior art, the cleaning machine 100 of the invention realizes synchronous working and synchronous shutdown of the spray gun 21 and the pump head assembly 11 through the first communication unit 13 and the second communication unit 23, thereby avoiding the problem of large current caused by the fact that the existing cleaning machine is not stopped when the gun is shut down; and, because pump head assembly 11 also can stop work after closing the rifle to make the pressure in high-pressure pump 111 be in normal range all the time, and then can cancel relief valve, temperature-sensing valve, make high-pressure pump 111's structure simpler, and then reduced the manufacturing cost of cleaning machine.
