In view of the above, the prior art still lacks a detergent-free washing device with strong dirt-removing power.
Disclosure of Invention
The invention aims to separate cathode water and anode water and develop a novel environment-friendly washing device only by using a washing device washed by cathode water aiming at the defects of the prior art.
The utility model provides a novel environmental protection washing device of no detergent, includes box, detergent module, the detergent module is including the liquid mixer, electrolysis trough and the washing liquid storage tank that connect gradually, the inlet tube of box shunts into blender inlet tube and washing inlet tube after getting into the box inside, blender inlet tube and blender intercommunication, the washing district intercommunication of washing inlet tube and box, the liquid mixer is provided with the salt mouth, add on the salt mouth embedding box wall, the liquid mixer provides the invariable electrolysis salt solution of treating of electrolysis salt concentration, the electrolysis trough includes anode region and the negative pole district that separates through the diaphragm, the negative pole district is connected with the washing liquid storage tank, the washing liquid storage tank with the washing district is connected, the electrolysis trough with the box electricity is connected.
The washing machine of the invention utilizes the box body of the traditional washing machine, and only replaces the chemical detergent adding device of the traditional washing machine with a detergent template capable of generating electrolyzed water, namely, changes the adding of laundry and the changing of the laundry into the adding of salt through the salt adding opening of the traditional washing machine. The detergent template separates anode water and cathode water of the electrolysis device, the cathode water is mainly used for washing, and after flowing into the washing area, the cathode water is mixed with tap water flowing in through the washing water inlet pipe according to a certain proportion, so that clothes in the washing area are washed. The washing effect of the cathode water is greatly improved compared with the prior art due to the strong washing capacity, and the washing capacity is at the same level as that of the existing detergent without adding any surfactant or cosurfactant. Meanwhile, the liquid mixer provides the brine to be electrolyzed with constant concentration, and the washing effect of washing the cathode water in unit volume every time can be almost the same, so that the washing capacity can be controlled by adjusting the using amount of the cathode water, the cathode water can be used more on occasions with more dirt, and less cathode water is used under the condition of common dirt, thereby providing the utilization rate of resources.
Preferably, the anode region is connected with a water outlet pipe of the box body through an anode water outlet pipe, the washing region is communicated with the water outlet pipe through a washing region water outlet pipe, and the anode region is communicated with the washing region through an anode branch pipe.
The anode water is directly discharged out of the box body through the water outlet pipe, and the water washed in the washing area is also discharged out of the box body through the water outlet pipe, but the anode water can wash the washing area after the washing area works for a period of time. The anode water is acidic and can be used for disinfection and removal of scale and other impurities which are difficult to clean.
Preferably, the liquid mixer is a venturi mixer, the ejector of the venturi mixer is directly installed on the main pipe, one end of the main pipe is communicated with the water inlet pipe of the mixer, the other end of the main pipe is communicated with the electrolytic cell, a saturated brine tank is arranged on the ejector, and a salt adding port is arranged on the saturated brine tank.
The main pipe of the Venturi mixer is thin in the middle and thick at two ends, the ejector and the main pipe form a mixing cavity in the middle, and tap water flowing into the main pipe is mixed with two streams of saturated saline water flowing into the ejector. The main pipe forms negative pressure in the mixing cavity by using the principle of the Venturi tube, tap water forms rotational flow under the action of atmospheric pressure, saturated salt water is sucked into the cavity and mixed with the tap water, and the salt water to be electrolyzed is formed after mixing.
Preferably, the saturated brine tank is filled with saturated brine and excess electrolytic salt.
The saturated brine tank contains excessive electrolytic salt, and the solubility of the saturated brine is temperature-dependent, but the temperature change of the indoor environment is not large during daily use, so the solubility of the saturated brine is also not large. When the device is actually used, the flow of tap water is adjusted to be constant, the solubility of the electrolytic salt of the saturated salt water is the saturated solubility, so that the amount of the salt water taken away by the tap water in unit volume when the two liquids are mixed is also constant, and the salt water to be electrolyzed with the solubility being a constant value can be obtained. Add the salt mouth not only and add the potassium salt, can also add water, compare traditional washing device and need the detergent, this application only need use the salt can, very environmental protection.
Preferably, the electrolytic salt is a strong base weak acid salt.
The invention uses most products existing in the market to carry out washing tests, and finds that the detergent has extremely strong decontamination capability only after the alkalinity exceeds 12, particularly exceeds 12.3, so that the detergent can meet wide washing requirements. In order to obtain a catholyte with a high pH, the present invention uses an alkaline potassium salt as the electrolyte. The pH of tap water is generally about 7, and according to the electrolysis principle, if electrolysis obtains alkali with pH of about 13, the anode region will obtain acid with pH of 1, that is, in order to obtain alkali with pH of more than 12.3, the anode region will obtain acid with pH of 1.7. High pH acids are very corrosive, very destructive to the material system and the resulting product is also unstable. The strong base and the weak acid are completely dissolved in water, the pH value after being dissolved in water is generally about 9, the saturated solution is close to 10, therefore, if the pH value is about 13, the pH value of the anode area is close to neutral or weak acid, and the system is hardly corroded. The solubility of the electrolytic salt can be controlled by the liquid level mixer, and the pH value of the diluted brine to be electrolyzed is 8-9, so that the anode water band after electrolysis has certain weak acidity, and the electrolysis efficiency and stability are very high. The acidity of the anode water is weaker than that of the anode water of electrolyzed neutral salt water, and the practice shows that the anode water can be used for sterilizing clothes, so that the application range of the anode water is greatly widened, the comprehensive washing capacity of a washing device is expanded, and the use efficiency of the electrolyzed water is improved.

What is electrolyzed in this application is the potassium salt, which is particularly important, the sodium salt that is widely used in the prior art. Practice shows that the active potassium ions of the potassium salt after electrolysis have very low harm to human bodies, and even if the solution is relatively strong in alkalinity, the solution is almost harmless to human bodies. And secondly, the ion particle size of potassium ions is larger than that of sodium ions and is close to that of chloride ions, so that the generated cathode water and electricity have stronger negativity and higher decontamination capability.

The main pipe forms negative pressure in the mixing cavity by using the principle of the Venturi tube, tap water forms rotational flow under the action of atmospheric pressure, saturated salt water is sucked into the cavity and mixed with the tap water, and the salt water to be electrolyzed is formed after mixing.
In a preferred embodiment, the saturated brine tank 27 is filled with saturated brine and excess electrolytic salt. The saturated brine tank contains excessive electrolytic salt, and the solubility of the saturated brine is temperature-dependent, but the temperature change of the indoor environment is not large during daily use, so the solubility of the saturated brine is also not large. When the device is actually used, the flow of tap water is adjusted to be constant, the solubility of the electrolytic salt of the saturated salt water is the saturated solubility, so that the amount of the salt water taken away by the tap water in unit volume when the two liquids are mixed is also constant, and the salt water to be electrolyzed with the solubility being a constant value can be obtained. Add the salt mouth not only and add the potassium salt, can also add water, compare traditional washing device and need the detergent, this application only need use the salt can, very environmental protection.
As a preferred embodiment, the electrolytic salt is a strong base weak acid salt. The invention uses most products existing in the market to carry out washing tests, and finds that the detergent has extremely strong decontamination capability only after the alkalinity exceeds 12, particularly exceeds 12.3, so that the detergent can meet wide washing requirements. In order to obtain a catholyte with a high pH, the present invention uses an alkaline potassium salt as the electrolyte. The pH of tap water is generally about 7, and according to the electrolysis principle, if electrolysis obtains an alkali with a pH of about 13, the anode region will obtain an acid with a pH of 1, that is, in order to obtain an alkali with a pH of more than 12.3, the anode region will obtain an acid with a pH of 1.3. High pH acids are very corrosive, very destructive to the material system and the resulting product is also unstable. The strong base and the weak acid are completely dissolved in water, the pH value after being dissolved in water is generally about 9, the saturated solution is close to 10, therefore, if the pH value is about 13, the pH value of the anode area is close to neutral or weak acid, and the system is hardly corroded. The solubility of the electrolytic salt can be controlled by the liquid level mixer, and the pH value of the diluted brine to be electrolyzed is 8-9, so that the anode water band after electrolysis has certain weak acidity, and the electrolysis efficiency and stability are very high. The acidity of the anode water is weaker than that of the anode water of electrolyzed neutral salt water, and the practice shows that the anode water can be used for sterilizing clothes, so that the application range of the anode water is greatly widened, the comprehensive washing capacity of a washing device is expanded, and the use efficiency of the electrolyzed water is improved.

Practice shows that the active potassium ions of the potassium salt after electrolysis have very low harm to human bodies, and even if the solution is relatively strong in alkalinity, the solution is almost harmless to human bodies. And secondly, the ion particle size of potassium ions is larger than that of sodium ions and is close to that of chloride ions, so that the generated cathode water and electricity have stronger negativity and higher decontamination capability.
In a preferred embodiment, the anode region 23 and the cathode region 24 are each provided with a pH sensor and an electrolysis controller which reads the measurement value of the pH sensor and stops the electrolysis when the cathode region reaches a set pH value.
