However, when the liquid is placed in the environment, the detergent will decompose and be contaminated. The hydrogen solution is used as the washing liquid in the automatic dishwasher. However, hydrogen peroxide is unstable and cannot be stored without decomposition. Therefore, the method and apparatus for generating hydrogen peroxide by electrolysis of hydrogen peroxide at the same time are described in U.S. Patent.

The provision of two electrolytes associated with the individual electrodes allows the user to select the solution that is most suitable for each electrode. By way of example, a metal chloride solution can be used to connect to the anode to provide an inexpensive and sufficient electrolyte, while a different metal salt solution is used as the cathode phase electrolyte to prevent the production of harmful by-products (e.g., chlorine). Advantageously, the other electrolytes and their associated electrodes are contained in different 丄 to allow for independent electrolyte control. This can be done by arranging the pump as , - the oxygen supply is lifted. This can be in the form of a chaotic supply.

The electrolyte associated with the cathode cavity 3 is referred to as a cathode electrolyte 10. The electrolyte associated with the anode cavity 2 is known as the anode electrolyte U. In the prior electrolytic cell for the manufacture of ruthenium peroxide, an electrolyte was used, which was shared between the anode cavity and the cathode cavity, and for the sake of convenience, this is typically the electrical charge of the chlorinated liquid H at the anode. In chemical reactions, extremely toxic chlorine is produced and this is ruled out – the use of fresh elements in home applications, for example in automatic dishwashers. Other electrolytes have also been proposed 'but they are generally more expensive to reduce sodium, and # when hydrogen peroxide is produced', as the electrolyte in the cathode cavity is used up, the invention must be applied to such things as user safety, cost, and Based on considerations such as availability and efficacy, the user is allowed to select the most appropriate electrolyte for each electrode. The catholyte 1〇 contains a sodium chloride solution before the activation of the electrolysis. This is a convenient choice for catholyte, especially in applications where this type of unit is used in automatic dishwashers. This type of dishwasher is typical and has a cavity, while the dishwasher salt (4) is present. Conventional salts have been used to maintain the efficiency of water softeners in dishwashing machines. The storage of this (4) and the water supply from the #地水管 provide a convenient source of sodium chloride solution. A suitable anolyte 11 is a metal sulfate solution such as sodium sulphate. Softened tap water can also be used as the anolyte. During the electrochemical reaction, Wei gas is produced at the anode 5, and (4) the gas can be harmlessly released. 2008-09-009 5 to t gas + or reused in the unit. In the electrolysis of hydrogen peroxide, the electrolyte 11 is not used up and thus does not need to be replenished. The polar cavity is not consumed by the electrochemical reaction. Appropriate 2: = material is titanium oxide coated with yttrium oxide _ net (listen.. used:: solution: 疋 must use the anode material produced by minimizing chlorine gas, for example, the main two *!! It is expensive '(four) oxidation The anode of the secret foundation is more expensive. The device of the anode is selected to make the anode not be the second: the cheaper materials are used. The other advantage is that the production rate of hydrogen peroxide is corrected. The thinning 4 allows electrical contact between the disintegrations 10, 11 in the chimes 2, 3, but does not allow electrolyte mixing. % 15 20 , solution early 1 very small ' is a few centimeters wide Therefore, a typical unit can only produce a small amount of hydrogen peroxide. A larger throughput can be achieved by a connection that is connected in series using multiple units. Another way to increase throughput is in the unit and accommodate In the cathodic electrolysis f storage tank 12, the (4) heteropolar (4) 1Q is aged as shown in Fig. 2. The catholyte storage tank 12 has a capacity of several liters, typically nearly five liters. Hydrogen peroxide is produced in the cathode cavity 3, and this hydrogenated hydrogen is overcast The electrolyte pump 13 is placed in the cathode electrolyte tank 12 to be replaced by more cathode electrolyte. As the cathode electrolyte circulates between the single cathode cathode chamber 3 and the cathode electrolyte tank 12, the concentration of peroxidation gas in the cathode electrolyte gradually increases. Via the chemical reaction of the cathode 6 (6), the surface of the cathode is recirculated between the unit 1 and the storage tank 12, and the batch of five liters of Weihua listen liquid with the concentration of 9200809009 can be manufactured. In typical household and industrial applications. It has been found that a concentration of about G35% is sufficient for most of the same, and is provided with a storage anode electrolysis tank M for accommodating the anode electrolyte n. The anode casting tank M has a lower, typically about - liter. The pump 15 is used in the electrochemical reaction of the anode cavity 2 ^ ° 70 ° ° in the anode 5, the anode electrolyte is not used up. The anode electrolyte U only needs to be occasionally supplemented with water from the main water supply In order to replace the anode which may have been evaporated by the storage tank 14, the reaction rate of: = early: 1 and thus increase the hydrogen peroxide "to hold the early:: the appropriate current density is required. The flow density must be % 疋 to maintain - the desired manufacturing rate. The reservoir of the metal salt solution 15 = and in order to bring the salt solution to the cathodic electrolyte, the conductivity is 6%, and the speed is brought to the desired level. The metal salt solution of 17 is sodium chloride solution, that is, strontium salt water. _; flow! should be arranged to detect the current through the single current. The second conductivity. In this embodiment, the current sensor Μ :::,: ''It generates a signal indicating the current intensity to the -Bao, ^ controller. The processor 19 periodically compares the signal and: === between the measured and predetermined current values ==Ϊ 17 of the pump 2〇. If the current measured by the sensor 18 is lower than the predetermined value, the processor is assigned 20200809009-the amount of brine. The brine from the reservoir 17 enters the person (four) and mixes it with the cathode and the cathode of the electrolysis unit 1 from the catholyte-like 12-guyin A + A ~ ° ° - enamel, 曰 human h. The liquid present in the static mixer 21 is incorporated into the early stage 1 and causes an immediate change in its conductivity.

As a result, the unit's electrical rate changes dynamically, regardless of the pressure at the i &&& voltage, supply voltage such as: cathodic quality. It also moves the temperature of the four qualities and the water supply. Can be used to help alert the user or the technology. Therefore, the data is heavy. The electrolysis f 1G is re-circulated in the cathode electrolyte tank 12 and the unit.

How much time will it take to update the negative servant? U 虱 ' to make a batch having a predetermined concentration is shown in Figure 7, 1 η - for example, as shown in Figure 8. Washing into the form of a domestic dishwasher should first be such that the machine 22 comprises an insulated outer cabinet 23, which comprises 12 200809009. The front wall of the seat 24 is rotatable to the bottom side thereof to set the door 25 to be placed in the second type. Plates, other pottery, cutlery and utensils = 'top. Typically, another shelf is placed on the housing 24 == nozzles 27, 28 are sprayed onto the plate, which is instead powered by an electric motor. If the motor and the motor are not displayed. The electrolytic cell storage tanks 12, 14 and hydrogen peroxide are housed in convenient locations for use in applications, for example, in compartments or side walls below the 10 15 20 board. In the case of t, the door 25 is opened to form a plate for machine loading, etc. 30. The operator-operable oscillating device 29 is placed in front of the 埶 element is operated to initiate the washing operation. The machine is filled with water and powered: LUf. When the water temperature is sufficient to allow the load to be fully washed, the pre-wash (4) drives the hot water to the water mist nozzles 27, 28 to activate - the water pipe = medium and is connected to the home owner. Bu 疋 3 3 3 3 3 3 3 3 3 3 3 3 3 3 控制 控制 控制 控制The controller is arranged to control the pump in the dishwasher; and electrolysis =. When the washing rhyme 22 is activated, the water flow splitter 32 =, :: the water of the water softener 33 connected inside the water pipe 16 to the dishwasher =: pool. This initialization is used to flush out the pre-washing step of the 7 U5 item from the item in the housing 24 to the ', particle and other dirt's clause $^. #Pre-washing step The Wei Wei is “powered by the power supply of the transformer and the rectified 200809009 from the L power supply. Therefore, the process of generating hydrogen peroxide is not started from scratch, but is stored. The remaining residual concentration in the solution begins. This continues until a batch of hydrogen peroxide having the desired concentration is produced, at which point the dishwasher is arranged to initiate its main washing step. 5 During the main wash, the connection The drain raft 34 to the cathode electrolyte tank 12 is activated so that a batch of hydrogen peroxide contained therein is dispensed into the wash tank holder 24 of the dishwasher 22. Hydrogen peroxide acts as a cleaning item in the tank holder _. It has been found that hydrogen peroxide is particularly suitable for the cleaning of glassware items, because glassware exposed to conventional cleaners may be scratched or net 10 ϋ hydrogen peroxide is decayed into oxygen and water, and when released to the environment When it is in the middle, it does not cause pollution. When this main washing step occurs, the catholyte tank 12 is replenished with fresh demineralized water from the main water pipe supply. The chlorine peroxide is made up; the sequence is restarted again. Until the batch has the desired concentration of hydrogen peroxide material. This (4) oxidation money is expected to be in the negative (four) solution ^ _ correct the dishwasher to run again 'At this point in time, the processor 19 decided to & The length of time that is stored' and thus the unit 丨 needs to replace the decaying nitrogen peroxide. This time can, for example, Γ 20 at 20 = one of the panels 30 visible visually conveyed to the dishwasher When the main washing has been completed, the tank 24 is emptied via the drain pump 35 and refilled with fresh water heated to flush the load. After flushing, the tank is drained again. Preferably, the drying _ including a short high-speed air flow 'α forces the residual water out of the recess 14 in the disk at 200809009, such as the upwardly facing bottom of the mug. This can be continuated by the slower flowing money of the drying plate. The method of shortening the time required to update the batch-peroxidation domain involves shortening its decay rate. By shortening the decay rate, the batch: the hydrogen peroxide will have a higher two than can be achieved so far: 】 Again. This can be controlled by the cathode The pH of the detoxification is achieved. The second = "5 yang - the batch of hydrogen peroxide has a slow decay; the members 10 15 20 ff 〇, Γ 5 〇Ι〇 ^ & 5, the decay rate is ready, if The pH is greater than ^^Λ^Γ^::ΡΗΛ8'64^ 0.225%. The day decays from the concentration of G.4% to the pH of the catholyte, and the pH of the solution, because of any change in the pH of the cathode, the anode is electrically intercalated to control the pH of the pH of the anode electrolyte. The pH of the preferred anolyte: quality is achieved. Alternatively, the soda solution - ^ natural St element II SI is called the anolyte is not used up, and the value is small and the loss of the volume contained in the tank. Via the most ':=: quality 4': the subsequent electrolyte of the polar electrolyte: hold a larger amount of money to the yang (four) solution tank 丨4. If Riga is required, the pH of the anolyte U is allowed to remain stable between each intrusion. Another stability of the pH of the anolyte 11 can be achieved by, for example, sealing the anolyte tank 14 to limit exposure of the anolyte to air so that the anode electrolyte does not need to be filled up so often. 5 The present invention has been described with reference to an automatic dishwasher using a hydrogen peroxide dishwashing bowl. However, the invention has many applications. For example, the invention can be used in other cleaning operations, such as floor cleaning applications, particularly in carpet cleaners. In a steam cleaner or steam iron incorporating the present invention, hydrogen peroxide will be heated, which is believed to increase its bleaching effect. 10 Hydrogen peroxide has a disinfecting effect, so the present invention can be used as both household and industrial to disinfect appliances, work surfaces, treat wounds and infections, and as a hand soap machine. Further applications of the present invention will become more apparent to those skilled in the art. 15 is a schematic diagram of an electrolytic unit constructed in accordance with the present invention; FIG. 2 is a diagram of a system for controlling the conductivity of the unit of FIG. 1. FIG. 3 is a diagram showing the unit of FIG. Figure 4 is a graph showing changes in hydrogen peroxide concentration in the cell of Figure 1; Figure 2 is a graph showing typical decay rate of hydrogen peroxide; Figure 6 is a cell pair showing Figure 1.
