fig. 2 is a schematic view (from a different perspective than fig. 1) of the washer of the present invention.
Detailed Description
The invention is described in further detail below with reference to the accompanying examples.
Referring to fig. 1 and 2, a cleaning machine, including basin body 1 and micro-nano bubble generating device 2, be provided with wiper mechanism in the basin body 1, like water pump and rotatory spray arm, be provided with on the lateral wall of basin body 1 and intake, integrative subassembly 11 of overflow, wiper mechanism and the integrative subassembly 11 of intake, overflow can adopt prior art, no longer describe herein.
The micro-nano bubble generating device 2 comprises a micro-nano bubble generator main body 21, a water inlet pipe 22, a three-way electromagnetic valve 23, an air inlet pipe 24, a first water outlet pipe 25 and a second water outlet pipe 26. The principle of micro-nano bubble generation is that water is pressurized through a closed cavity to improve gas solubility, air in the cavity is fully dissolved, and then the water is released through decompression. The micro-nano bubble generator main body 21 can adopt the prior art and generally comprises an inner cylinder, a cavity, an upper cover, an O-shaped ring and the like. The one end of inlet tube 22 is provided with water inlet solenoid valve 27 to with outside water source intercommunication, the other end of inlet tube 22 is connected to the top of micro-nano bubble generator main part 21, and with the inside cavity intercommunication of micro-nano bubble generator main part 21, in order to provide water to micro-nano bubble generator main part 21. The air inlet pipe 24 is arranged at the top of the micro-nano bubble generator main body 21 and communicated with the cavity inside the micro-nano bubble generator main body 21, so that outside air can enter the micro-nano bubble generator main body 21. The air inlet pipe 24 is provided with a check valve 241, so that air can enter the micro-nano bubble generator main body 21 from the outside, but cannot flow out of the micro-nano bubble generator 21.
The three-way electromagnetic valve 23 is arranged at the bottom of the micro-nano bubble generator main body 21 and has a water inlet 231, two water outlets, a first water outlet 232 and a second water outlet 233. A water inlet 231 of the micro-nano bubble generator is communicated with the inside of the micro-nano bubble generator main body 21, a first water outlet 232 is communicated with the water inlet and overflow integrated assembly 11 on the side wall of the water tank body 1 through a first water outlet pipe 25, a second water outlet 233 is connected with the side wall of the water tank body 1 through a second water outlet pipe 26 and is communicated with the inside of the water tank body 1, and the joint of the second water outlet pipe 26 and the water tank body 1 is lower than the second water outlet 233 of the three-way electromagnetic valve 23.
The aperture of the first water outlet 232 of the three-way electromagnetic valve 23 corresponding to the first water outlet pipe 25 is relatively small, so that the pressure difference between the front and the back of a valve port can be increased to improve the concentration of micro-nano bubble water, and the cleaning effect is improved; the aperture of the second water outlet 233 of the three-way electromagnetic valve 23 corresponding to the second water outlet pipe 26 is relatively larger than that of the first water outlet 232, so that gravity drainage is realized, and the three-way electromagnetic valve can be matched with the one-way valve 241 at the top to improve drainage efficiency, and meanwhile, air is supplied to provide an air source for next circulation of the cleaning machine.
The volume of the micro-nano bubble generator main body 21 is matched with the water consumption of the last cleaning of the cleaning machine.
The washing process of the washing machine during washing dishes is generally divided into four steps, wherein the first step of washing time is longest, the dish washing machine heats water, the washing machine is matched with the effect of dish washing powder, stains on the dishes are washed, the second step of washing time is shorter, mainly the first step of residual dirt is washed away, the third step of washing time is the same, the fourth step of water can be used for washing the dishes continuously, therefore, except that the first step of water and the second step of water are dirty, the third step of water and the fourth step of water are clean except large-particle stains, and the discharged water can be collected and reused.
If intake according to conventional mode, water through intake solenoid valve 27 back, enter into first outlet pipe 25 via micro-nano bubble generator main part 21, and then enter into basin body 1 in, by the break-make of this route of three-way solenoid valve 23 direct control, the drawback that this kind of mode exists is: when the air in the micro-nano bubble generator main body 21 is dissolved, micro-nano bubbles are not generated any more, and continuous supply cannot be realized. At this time, water in the cavity of the micro-nano bubble generator main body 21 needs to be discharged, and meanwhile, the check valve 241 at the top is used for automatic air supply for the next cycle to continue use, so that one path of the second water outlet pipe 26 is added.
Specifically, the control method of the cleaning machine during cleaning includes the following steps:
1) assuming that the cleaning machine has n cleaning procedures, when the first n-1 cleaning procedures are carried out, like the first three cleaning procedures, bubble water is generated after water of an external water source passes through the micro-nano bubble generating device and is discharged into the water tank body 1 through the first water outlet pipe 25 for conventional cleaning;
2) when the nth cleaning procedure is started, bubble water generated by the micro-nano bubble generator main body 21 is drained into the water tank body 1 through the second water outlet pipe 26 under the action of gravity for cleaning; considering that the last water inflow of the cleaning machine is relatively close under different modes and different time sequences, the volume in the cavity of the micro-nano bubble generator main body 21 is matched with the last water consumption of the cleaning time sequence; in the process of above-mentioned drainage, check valve 241 is opened because the pressure differential effect, and the air gets into the cavity in the micro-nano bubble generator main part 21 automatically, and until the water evacuation, the air is full of, returns initial condition from this, prepares for next washing, before using promptly at every turn, can both ensure that the cavity of micro-nano bubble generator main part 21 is full of the air, can produce micro-nano bubble in real time.
The cleaning process can be completely combined with the time sequence of the cleaning machine, the current time sequence of the cleaning machine which is divided into a plurality of channels for water inlet is fully utilized, water is not wasted in the process, a pump is not needed to be used as a power source for supplementing air, and complete periodic circulation is realized under the condition of no power source.
Through the physical action of the micro-nano bubbles generated by explosion in water and the chemical action of negative charges on the surface to improve the interfacial activity, the cleaning agent has better effects on foreign matters on the surfaces of fruits, vegetables and dishes, and has better effects on the surface sterilization and pesticide residue removal of the fruits and vegetables; cleaning efficiency: due to the activity of the micro-nano bubble interface, the activity of the dish washing powder can be improved, the using amount of the dish washing powder is reduced, and meanwhile, the cleaning time can be reduced; the device need not to adopt any pump as the power supply, and control is simple, and the in-process can not cause the waste of water, compares with the ultrasonic vibrator, has more cost advantage.
