fig. 2 is a schematic view of the cleaning machine of the present invention (from a different view angle than fig. 1).
Detailed Description
The invention is described in further detail below with reference to the embodiments of the drawings.
Referring to fig. 1 and fig. 2, a cleaning machine includes a water tank body 1 and a micro-nano bubble generating device 2, a cleaning mechanism, such as a water pump and a rotary spray arm, is disposed in the water tank body 1, and a water inlet and overflow integrated component 11 is disposed on a side wall of the water tank body 1, and the cleaning mechanism and the water inlet and overflow integrated component 11 can adopt the prior art, which is not described 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 the gas solubility, air in the cavity is fully dissolved, and then the water is released through decompression. The micro-nano bubble generator body 21 may be of a conventional technology, and may generally comprise an inner cylinder, a cavity, an upper cover, an O-ring, etc. One end of the water inlet pipe 22 is provided with a water inlet electromagnetic valve 27 to communicate with an external water source, and the other end of the water inlet pipe 22 is connected to the top of the micro-nano bubble generator body 21 and communicates with a cavity inside the micro-nano bubble generator body 21 to supply water to the micro-nano bubble generator body 21. The air inlet pipe 24 is provided at the top of the micro-nano bubble generator body 21 and communicates with the cavity inside the micro-nano bubble generator body 21 so that the outside air can enter the inside of the micro-nano bubble generator body 21. The air inlet pipe 24 is provided with a check valve 241 so that air can enter the inside of the micro-nano bubble generator body 21 from the outside, but cannot flow out from the inside of the micro-nano bubble generator 21 to the outside.
The three-way electromagnetic valve 23 is disposed at the bottom of the micro-nano bubble generator body 21, and has a water inlet 231 and two water outlets, a first water outlet 232 and a second water outlet 233. The water inlet 231 is communicated with the interior of the micro-nano bubble generator main body 21, the 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 the first water outlet pipe 25, the second water outlet 233 is connected with the side wall of the water tank body 1 through the second water outlet pipe 26 so as to be communicated with the interior 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 caliber of the first water outlet 232 of the three-way electromagnetic valve 23 corresponding to the first water outlet pipe 25 is relatively smaller, so that the pressure difference between the front and the rear of the valve port can be increased to improve the concentration of micro-nano bubble water and the cleaning effect; the caliber 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, the gravity drainage can be matched with the one-way valve 241 at the top, the drainage efficiency is improved, air supplementing is performed, and an air source is provided for the 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 dish washing is generally divided into four channels, wherein the washing time of the first channel is longest, the dish washing machine heats water, the dish washing powder is matched, stains on tableware are washed down, the second channel is shorter, the second channel is mainly used for washing away residual dirt of the first channel, the third channel is also used, the fourth channel of water can continuously wash dishes, and therefore, besides the fact that the first channel and the second channel of water are dirty, the third channel of water and the fourth channel of water are clean except for large-particle stains, and the discharged water can be collected and recycled.
If water is fed in a conventional manner, after passing through the water feeding electromagnetic valve 27, the water enters the first water outlet pipe 25 through the micro-nano bubble generator main body 21 and then enters the water tank body 1, and the three-way electromagnetic valve 23 directly controls the on-off of the passage, the defects of the mode are that: when the air in the micro-nano bubble generator main body 21 is dissolved, micro-nano bubbles are not generated any more and cannot be continuously supplied. At this time, the 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 utilized to automatically supplement air for the next cycle to continue to use, so that a path of second water outlet pipe 26 is added.
Specifically, the control method of the cleaning machine during cleaning comprises the following steps:
1) Assuming that the cleaning machine has n cleaning procedures, when the first n-1 cleaning procedures are performed, for example, when the first three cleaning procedures are performed, bubble water is generated after water from 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, so that conventional cleaning is performed;
2) When the nth cleaning procedure is started, bubble water generated by the micro-nano bubble generator main body 21 is discharged into the water tank body 1 through the second water outlet pipe 26 under the action of gravity for cleaning; considering that the final water inflow of the cleaning machine is relatively close under different modes and different time sequences, the inner volume of the cavity of the micro-nano bubble generator main body 21 is matched with the final water consumption of the cleaning time sequence; in the process of draining water, the one-way valve 241 is opened under the action of pressure difference, air automatically enters the cavity in the micro-nano bubble generator main body 21 until water is emptied, the air is full, and the air returns to an initial state, so that preparation is made for next cleaning, namely, before each use, the air can be fully filled in the cavity of the micro-nano bubble generator main body 21, and micro-nano bubbles can be generated in real time.
The cleaning process can be completely combined with the time sequence of the cleaning machine, the current time sequence of 'dividing into a plurality of water inlets' of the cleaning machine is fully utilized, water is not wasted in the process, a pump is not needed to be used as a power source to supplement air, and complete periodic circulation is realized under the condition of no power source.
The micro-nano bubbles explode in water to generate physical action and chemical action of negative charge on the surface to improve interfacial activity, the cleaning agent has good effects of cleaning foreign matters on the surfaces of fruits and vegetables and bowls and removing bacteria and pesticide residues on the surfaces of the fruits and vegetables; cleaning efficiency: due to the action of micro-nano bubble interfacial activity, the activity of the dish washing powder can be improved, the dosage of the dish washing powder can be reduced, and meanwhile, the cleaning time can be shortened; the device does not need to adopt any pump as a power source, is simple to control, does not cause water waste in the process, and has more cost advantage compared with an ultrasonic vibrator.
