Abstract

A washing machine in which metal ions exhibiting an antibacterial action can be added to water with a target concentration regardless of the water quality or the water temperature. A pair of metallic electrodes are applied intermittently with a voltage and metal ions are eluted alternately from one and the other electrodes. Water quality and water temperature are then detected from an applying voltage required for feeding a specified current and, depending on the detection results, a current being fed between the electrodes, an elution time of metal ions (T4), a voltage applying time (T2) or a voltage application suspension time (T3) is altered thus adjusting elution quantity of metal ions.

Description

200523427 IX. Description of the invention: [Technical field to which the invention belongs] The present invention relates to a washing machine, which has the function of adding antibacterial metal ions to the water used. [Previous technology] When I wash clothes in a washing machine, I often add a surface treatment agent in water (especially rinsing water). Softeners and sizing agents are commonly used surface treatment agents. In addition, recently, more and more people think that it is necessary to use a surface treatment method that can make clothes antibacterial after washing. From a hygiene point of view, it is best to dry the clothes in the sun after washing. However, in recent years, the proportion of working women has grown, and households have gradually transformed into family units. As a result, the number of households without people at home has increased during the day. Among these families, it is only possible to do it indoors in Nikyo. Even in homes where people are home during the day, when it rains, clothes can only be dried indoors. Compared with clothes dried in the sun, fine g and mildew g are more likely to grow on clothes dried in the interior of Nikyo after washing. During periods of high humidity and low temperatures (such as the rainy season), it takes a long time for the laundry to dry out after washing. In this case, the above tendency will be very obvious. The washed clothes will have a bad smell according to the proliferative state of bacteria and mold. "In the courtyard where the indoor shouting method must be often used and there is no choice", it is extremely necessary to perform anti-g treatment on the clothes. Bacteria multiply on clothing. · Recently, many clothes have undergone antibacterial and deodorizing surface treatments and microorganism treatments. Made for you ... _ Department Ren You Nuo All the fabrics in the faucet are anti-bacterial and deodorizing surface treatments in advance and it is not easy. Furthermore, the effectiveness of antibacterial and deodorizing 95732.doc 200523427 surface treatment will also be reduced after repeated cleaning. In this situation, the predecessors have created the concept of "antibacterial treatment of clothes every time they are washed." Japanese Utility Model Application Laid-open No. H5-74487 (1993) describes an electric washing stick with an ion generator 'β ion generator which can produce germicidal metal ions such as silver ions or copper ions. The washing machine described in Japanese Patent Application Laid-Open No. 2000-93691 can generate an electric field, which is sterilized by a cleaning solution. Japanese Patent Application Laid-Open No. 2001-276484 describes a washing machine having a silver ion adding unit which can add silver ions to washing water. If a washing machine uses metal ions with antibacterial properties, an ion dissolving unit is usually provided in its structure, which can dissolve a metal electrode into metal ions by applying a voltage between the electrodes. For example, if silver ions are to be added, the electrode on the anode side can be made of silver and immersed in water. When we apply voltage to the electrode, the anode produces a reaction of 8-Ag + + e_. This action can dissolve the electrode in water to form silver ions Ag +, thereby depleting the anode. In theory, according to Faraday's law of electrolysis, the amount of dissolution is proportional to the charge applied by us. However, the efficiency of dissolving a metal electrode into metal ions (the ratio of the actual dissolution amount to the theoretical dissolution amount obtained according to Faraday's law of electrolysis, that is, the ratio of the actual dissolution metal amount to the applied charge number: (metal Dissolved amount) / (charge)) will change according to the different water quality in different places or seasonal differences in water temperature. Therefore, it may not be possible to generate the required amount of metal ions, and therefore it is not possible to stably supply the predetermined metal ion concentration, making it difficult for us to perform the required antibacterial treatment on the laundry 95732.doc 200523427. [Summary of the Invention] In order to solve the above-mentioned problems, one object of the present invention is to provide a washing machine that can add antibacterial metal ions to water at a predetermined concentration regardless of water quality or temperature. To achieve this, the present invention provides a washing machine, which includes a pair of metal electrodes, and when the electrodes are immersed in water to be used, a voltage is applied between the electricity and the electrodes, and a voltage is induced between the electrodes. The current is used to add metal ions generated by dissolving an electrode to the water to be used, and the magnitude of the current between the electrodes can be changed according to at least one of water quality and water temperature. Although-the efficiency of metal dissolving into metal ions will change with water f or water temperature ', but the amount of current between the electrodes of the washing machine can be changed according to-or both of water quality and water temperature, to adjust each unit time due to metal dissolution : Generated = amount of ions. Since the amount of water is usually known per time, the metal ions can be added to water at a predetermined concentration by adjusting the dissolved amount per unit time. Available—the dissolution time of the metal electrode into metal ions can be fixed.凊 Note that at least two electrodes need only operate in pairs. Five people can also set up more than three electrodes in a structure. The pair of electrodes can also be provided in the present invention. The washing machine includes-pair of metal electrodes, and the electrodes are immersed in the water to be used, and a voltage of __ is applied between the electrodes. Initiate a current, nightmare Word mouth> Metal ions generated by Gujie one electrode are added to the water to be used φ ^ τ, of which a metal 95732.doc 200523427 is used to dissolve the metal ions into a single water solution time It can be changed according to at least one of water quality and water temperature. The washing machine can change the dissolution time, thereby adjusting the total amount of metal ions generated by dissolution. The dissolution time can be changed according to water quality or water temperature, so that the 7-group ions can be added to a single-use wafer at a predetermined concentration regardless of the dissolution efficiency. The dissolution efficiency that varies with water quality or water temperature can determine-the amount of metal ions that the metal electrode dissolves in each unit time. The present invention also provides a washing machine, which includes a pair of metal electrodes, and when the electrodes are immersed in water to be used, a voltage is applied between the electrodes, and a current is induced between the electrodes, so that the cause The metal ions generated by dissolving an electrode are added to the water to be used, wherein the current between the electrodes is fixed, and the voltage applied between the electrodes can be changed according to at least one of water quality and water temperature. The washing machine can change the applied voltage to adjust the amount of metal ions that the metal dissolves in each unit time, and at the same time, the current between the electrodes is kept constant. The electric voltage applied between these electrodes can be changed according to the water quality or water temperature, so that the metal ions can be added to the water used in a single pre-concentration regardless of the dissolution efficiency. —Metal electrode dissolves into a metal reaction system (such as — + + 〇, so if you use solid electricity ~, you can easily calculate the dissolved amount from the applied voltage. The present invention also provides-washing machine, which includes-for metal Electrode, and when = is immersed in water to be used, an electric dysprosium is applied between the electrodes to induce a current between the electrodes, so that metal ions that dissolve an electrode are added to the water to be used ' The voltage is intermittent 200523427. The yoke is used between the electrodes, thus forming an application time (the voltage will be applied) and a pause time (there is no electric dust applied), and the polarity of the electric voltage applied between these electrodes will be The cycle mode is reversed, and we can also change at least one of the application time and the pause time according to the water quality and temperature--〇

"Washing machine can change the ratio of" time to apply voltage between electrodes "to" time to apply electricity M temporarily "to adjust the amount of dissolution. The application time; the pause time is changed according to the water quality or water temperature, so as to determine the efficiency of the lysis, can be added to a single concentration: The sum of the application time and the pause time can be fixed. The polarity of the internal voltage in each application will be reversed 'so as not to consume only one electrode, the second = short life, and it can also prevent the impurities fixed on the surface of an electrode from reducing the function of the 5H electrode. In the washing machine of the present invention, it is best to change the application time and the pause time to two degrees, so that the sum of the application time and the pause time is fixed.

Make: belongs to the ion; the polarity reversal cycle will be fixed, such as the trowel is generated by the dissolution of the two electrodes. In addition, if the application time and the pause time are used to add metal ions to a single time with a predetermined degree of indifference: Second, it is easier to dissolve the electrode into metal ions, which can widely stop the metal washing machine water supply. Phantom stays in Yuancheng state until Zhongming's washing machine. The best application time and pause time are at least based on the current between the electrodes. If one can correctly set the amount of metal that can be measured by a metal electrode, the amount of ions in the monsoon is because 95732.doc -10- 200523427 the amount of dissolution is determined by the magnitude of the current and the time when the current passes ^. The washing machine of the present invention can preferably detect at least one of water quality and water temperature, and the method is to measure the amount of voltage to be applied between the electrodes to know the current of a predetermined magnitude, which is caused between the f electrodes—predetermined The amount of current required to apply :::: 电 :: Number varies, and the conductance is ^ / plate of ~ ginger. Oral people can measure the electric current required to apply a current of a predetermined magnitude, and to obtain the lean information required to adjust the amount of metal ion dissolved in the electrode. / Only found that-the efficiency of the metal electrode to dissolve into metal ions tends to decrease as the known voltage decreases. Because of & electrical measurement is extremely helpful in regulating the amount of dissolution. For example, if you want to increase the amount of dissolution, you can refer to the increase and decrease rates when the current between the electrodes increases, when the dissolution sundial grows, when the application time is selected, or when the pause time is shortened. Value ^ Your support for 5 weeks 0 According to the instructions of the operator, the washing machine of the present invention may change the dissolving amount according to the water temperature of at least one of the toilets. The washing water is usually clean water, but even the quality of the water varies from region to region, so that the efficiency of dissolving metal electrodes into metal ions is different from other regions. In areas with low dissolution efficiency, it is best to change the magnitude of the current according to water quality or water temperature, dissolution time, application time, or pause time. However, in areas with standard dissolution efficiency, it may not be necessary to change. In order to save water, some people use the remaining water of Japanese-style bathtubs. In this case, because the water quality and water temperature have changed, so that the dissolution efficiency changes' parameters must be changed. If the change can be made according to the operator's instructions, the metal ion 95732.doc -11-200523427 can be added to the water used in the same washing machine at a predetermined concentration regardless of the regional water. The washing machine of the present invention preferably can memorize the changed values. This eliminates the need to set values such as current, dissolution time, application time, or pause time each time the washing machine is used, thereby reducing the burden on the operator. For example, it can be changed in the initial stage after the washing machine is installed, that is, according to the water quality of the clean water supplied by the installation site, to memorize the changed value, so that it is not necessary to set the corresponding parameters again in the normal use in the future. In addition, if you use the remaining water of a Japanese-style bathtub, you can also change the parameters to memorize the value. In this way, you do not need to reset the parameters if the same situation occurs again. In the washing machine of the present invention, it is preferable to change the method for a washing drum containing laundry to be detected, and detecting at least one of the water quality and the water temperature in the drum. The quality of the water in the cleaning drum (that is, the water containing the laundry) can make a difference in the effect of antibacterial treatment with metal ions. Especially after the surface treatment agent is injected, the effect of the antibacterial treatment may be reduced due to a component of the surface treatment agent. We can change one or more of the current, dissolution time, application time, and pause time according to the water quality or temperature in the cleaning drum, and add metal ions at an appropriate concentration to achieve the desired antibacterial effect. It is best to detect the light transmittance and use it as the water quality in the cleaning drum. If you use this design, you can know the water quality in a short time under simple control.

The upper cover 16 is pivotable in a vertical plane and covers the clothes insertion opening 15 from above. The casing 10 is provided with a water drum 20 and the above-mentioned cleaning drum 30, which can also serve as a dewatering drum. The shapes of the water drum 20 and the cleaning drum 30 are both cylindrical cups with open top surfaces, the axes of which are aligned in the vertical direction, and after assembly, the water drum 20 will surround the cleaning drum 30 concentrically with each other. The water drum 20 is hung downward by a suspension member 21. Suspension members 21 are provided in four positions. 'The lower end of the outer surface of the water drum 20 is connected to the housing 1095732.doc -13- 200523427 and the # water drum 20 is supported so that it can correspond to the inner surface of a water The corner part swings in the plane. The second washing roll with 30 has a gradually widening and gradually expanding outwards = the circumferential wall has a plurality of drainage holes M surrounding the topmost part of it year by year. * This phase has no outlet. In other words, the cleaning drum 3G belongs to the so-called "no hole". The weight 32 is attached to and surrounds the periphery of the opening on the top surface of the cleaning drum 3 (). The roller room 3G is dehydrated after washing and rotates at high speed. Vibration of the cleaning drum 30 can be suppressed. A vibrator 33 'is provided on the inner bottom surface of the washing drum 30, which allows washing or rinsing water to form a water flow in the drum. A driving unit 40 is disposed on the bottom surface of the water drum 20. The driving unit 40 includes a motor 41, a crutch mechanism 42, and a braking mechanism 43. A dewatering shaft and a vibrator shaft 45 protrude upward from a central portion of the driving unit. The dewatering shaft 44 and the vibrator shaft 45 belong to a biaxial structure, and the vibrator shaft shirt is enclosed in the dewatering shaft 44. The dewatering shaft 44 extends into the dewatering drum 20 from the bottom up and is then connected to the washing drum 30 to support the drum. The vibrator shaft 45 penetrates the water drum 20 from bottom to top, then enters the washing drum 30, and is connected to the vibration 1§ 33 to support the vibrator 33. Between the dewatering shaft 44 and the water drum 20 and between the dewatering shaft 44 and the vibrator shaft 45, seal members are provided to prevent water leakage. A water supply valve 50 that can be opened and closed electromagnetically is provided in the space below the back plate 12. The water supply valve 50 has a connecting pipe 51 passing through the back plate 12 upward. A water supply hose (not shown) can be connected to the connection pipe 51 to supply fresh water, such as tap water. The water supply valve 50 can supply water to a container-shaped water supply port 53. The position of the water supply port is 95732.doc -14- 200523427 facing the inside of the cleaning tank 30. The port Jc port 5 3 has the same as shown in Figure 2, || Shi Gou. The surface is provided with an opening π'-drawer 53a (-investment box) can be inserted through the opening: the water supply port. The interior of the drawer ... is divided into several parts (in this specific example, it is divided into left and right parts). The left part is a cleaning agent chamber ^, and Fig. 2 is a schematic vertical sectional view of one of the water supply ports 53. Feed port μ front end table

Can be used as a preparation space for detergents. The right part is a surface treatment agent chamber 55 'which can be used as a preparation space for the surface treatment agent. A water injection port% is provided at the bottom of the detergent chamber 54 and its opening is located inside and at the water supply port μ. A siphon portion 57 is provided in the surface treatment agent chamber 55. The part of the water supply port 53 below the drawer 53a can be used as a water injection port%, and the water is injected into the drum 30 to wash it. The siphon part 57 includes an inner tube 57a and a cap-shaped outer tube 57b. The former is formed vertically from the bottom surface of the surface treatment agent chamber 55, and the latter covers the inner tube 57a. A gap is formed between the inner tube 57a and the outer f57b to allow water to pass through. The bottom of the inner tube ... is open towards the bottom of the water supply port 53. A predetermined gap is left between the bottom surface of the surface treatment agent chamber 55 at the bottom end surface of the outer tube 57b, and this gap can serve as a water inlet. In the process of injecting the wafer into the surface treatment agent chamber 55 until the water exceeds the top of the inner tube 57a, the siphon effect can be sucked out through the siphon part. 〇 中. The water supply valve 50 includes a main water supply valve and a primary water supply valve. The main feed water valve 50a is set to have a relatively large flow rate. As for the secondary water supply, ^^ is set to have a relatively small flow. The method of setting the flow rate is to use different nozzles in the main water supply 95732.doc -15- 200523427 valve 50a and the second water supply valve 50b. Also, the water supply valve can have the same structure. Different flow control: The structure is to set the size of the flow. The main wafer supply is connected to the sub-floor with a connection tube 51. The main water supply valve 50a is connected to an opening at the top of the water supply port by a main water supply path 52a. This opening leads directly to the cleaning agent chamber 54. Therefore, a large-flow water flow from the muscle in the main feed water tank is injected into the detergent chamber 54 from the main feed path. On the other hand, the secondary water supply valve 5 centimeter is connected to the opening of the top of the water supply port 53 by the secondary water supply path. The opening faces the surface treatment agent center. Therefore, the small-flow water flowing from the secondary water supply valve 50b is injected into the surface treatment agent chamber 55 through the secondary water supply path 52b. In other words, the water flow path from the main water supply valve 50a to the cleaning drum 3G through the detergent chamber 54 is different from the water flow path from the secondary water supply 50a to the cleaning drum 30 through the surface treatment agent chamber 55. Hereinafter, description will be made again with reference to FIG. 1. A drain hose 60 is attached to the bottom of the water drum 20 so that the water in the water drum 20 and the cleaning drum 30 is drained out of the casing 10. The water system flows into the drain hose 60 from the drain pipes 61 and 62. The drain pipe 61 is connected to the bottom surface of the water drum 20 near the outer periphery, and the drain pipe 62 is connected to the bottom surface of the water drum 20 near the center. A frame-shaped partition wall 63 is fixed to the inner bottom surface of the water drum 20 to close the connection between the water drum 20 and the drainage pipe 62. An annular sealing member 64 is attached to the top of the partition wall 63. This sealing member 64 will contact the outer periphery of a disc 65 fixed to the inner bottom surface of the cleaning drum 30, thereby forming an independent drainage space 66 between the water drum 20 and the cleaning drum 30. The drainage space 66 can communicate with the interior of the cleaning drum 30 through a drainage port 67 formed at the bottom of the cleaning drum 30. 95732.doc -16-200523427. The drain pipe 62 is provided with a drain valve 68 that can be opened and closed electromagnetically. An air baffle device 69 is provided in the drain pipe 62, upstream of the drain valve 68, and a duct 70 extends from the air baffle device 69. A water level switch 71 connected to the top of the duct 70 can be used to detect the amount of water in the cleaning drum 30 or the water drum 20. A control portion 80 is provided on the front side of the casing 10. The control section 80 is located below the top panel 11 and can receive an operation instruction from the author through an operation / display section provided on the top surface of the top panel u as 81, and sends the operation instruction to the driving unit 40 and the water supply valve. 50 、 and drain valve 68. The control section 80 may also send a display instruction to the operation / display section 81. The control section 80 includes a driving circuit 120 (see FIG. 9) of an ion dissolving unit 100 (to be described later). A flow detector 185 is installed on a water supply path from the main water supply valve 50a to one of the main water supply paths 52a. The flow detector 185 may be a well-known stream ef. The flow detector i 85 is a part of the water supply valve 50 in FIG. J, but its installation position need not be specified here, and it can be installed in the ion dissolution unit 100 or the water supply port 53. Another _ flow method is to use the water level switch 71: measure the amount of water per unit time, # calculate the flow from the amount of water change, or calculate the flow from the time required for a predetermined change in water. The ion dissolving unit 100 of the washing machine 1 is connected below the main water supply pipe 52a, the general, FIG. 3 to 10 to explain the structure and function of the ion dissolving unit 100, and the ion dissolving unit ⑽ (its system , Installed in the washing machine 丨). Fig. 3 is a partial top plan view showing the arrangement of the water supply valve 50, the ion dissolution unit-, and the water supply port 53. The ion dissolving unit map = 95732.doc 200523427 is directly connected to the main water supply valve 50a and the water supply port 53 respectively. In other words, only the ion dissolving unit 100 constitutes the entire main water supply path 52a. In the configuration of the secondary water supply path 5 2b ', a pipe system protrudes from the water supply port 5 3 and is connected to the secondary water supply valve 50b by a hose. Please note that in the schematic diagram of FIG. 1, the water supply valve 50, the ion dissolving unit 100, and the water supply port 53 are arranged from the front end to the rear end of the washing machine 1. However, in a real shell washing machine 1, the components are not along the direction (From back to front), and from left to right. 4 to 8 show the structure of the ion dissolving unit 100. Figure 4 is a top plan view of one of the ion dissolving monomers το 100. FIG. 5 is a vertical cross-sectional view of one of the ion dissolving units 100, and the position of the cross-section is along the line A-A in FIG. 4. FIG. 6 is a vertical cross-sectional view of one of the ion dissolving units 100, and the position of the cross-section is along the line 3_8 in FIG. 4. FIG. 7 is a horizontal cross-sectional view of an ion dissolving unit 100. FIG. 8 is a perspective view of an electrode in the ion dissolving unit 100. FIG. The ion dissolving unit 100 has a casing 11 made of transparent or translucent synthetic resin (non-colored or colored), or opaque synthetic resin. The outer casing 110 includes-a casing 11Ga and-an upper cover! The former has an open top surface, and the latter can close the open top surface (see Figure 5). The shape of the casing 110a is long and narrow. It has a water inlet 1 at one end in the length direction, and a water outlet J J 2 at the other end in the length direction. The inflow port 出 and the outflow 112 are both g-shaped. The cross-sectional area of the outflow port 112 is smaller than the cross-sectional area of the inflow port ill. 0, outer: 110 is installed on a horizontal plane along its length direction, so that the square A of the flat women's clothes and the body 11 (^) form a The 95732.doc -18- 200523427 slope that descends toward the outlet 112 (see Figure 5). In other words, the outlet 112 is located at the lowest elevation of the internal space of the housing 110. The upper cover 110b is fixed to the housing with four screws 170 110a (see FIG. 4). A sealing ring 171 is provided between the housing 110a and the upper cover 110b (see FIG. 5). The two plate-shaped electrodes 113 and 114 are arranged in the housing 110 in a manner facing each other. It is in accordance with the direction of the water flow from the inlet 111 to the outlet 112 (see Figures 6 and 7). If we have water in the case 110, a predetermined voltage is applied between the electrodes 11 3 and 114, and the electrode The anodes in 113 and 114 will dissolve, causing an electrode metal to generate metal ions. In the structure of electrodes 113 and 114, 'each silver plate has an area of 2 cm x 5 cm and a thickness of about 1 mm, and the spacing About 5 mm. The material of the electrodes 113 and 114 is not limited to the above Any silver can be used as long as it can produce metal ions with resistance to annihilation. For example, the metal can be selected from silver, copper, silver-copper alloy, zinc, and other metals. The following metal ions can produce excellent sterilization and Anti-mold effect ······································································································································································· The bactericidal and anti-mold effect is produced in a similar manner. Metal vapors formed on the electrode surface in the form of scale will prevent the metal electrode from dissolving into metal ions, among which silver gas is less soluble. Due to copper chloride and chlorination Zinc has a high ionization tendency and is easy to dissolve. Therefore, an electrode made of silver-copper or silver-zinc alloy is less likely to form a uniform gaseous coating on the electrode, which can prevent dissolution from being hindered. Whether or not a voltage is applied will determine whether a metal electrode 95732.doc -19- 200523427 dissolves into metal ions. We can control the amount of current or the length of time to control or adjust Save a metal electricity and use the amount of metal per day. In the material dissolving unit 1 () (), the metal ionization / small addition of metal ions, or the concentration of 厶 ions can pass through electricity _, controllability If it is all due to the early failure to ensure better operability and poor maneuverability. When combined, the electrodes 113 and 114 are not absolutely parallel. Ding You looks down on it, relative to the housing u〇 = 水: "electrodes 113 and The setting method of 114 is from the upstream end to the downstream end. In other words, the distance between the electrodes is gradually reduced from the inflow port ⑴ to the outflow port 112 (see FIG. 7). The shape of the casing ma in a plan view from above It is tapered from the end of the stream opening towards the end of the outflow opening 112. In other words, the cross-sectional area of the inner space of the casing m is tapered from the upstream end to the downstream end. The electrodes 113 and 114 are rectangular in front view and each have terminals 115 \ 116. The terminals 115 and 116 are suspended from the lower ends of the electrodes 113 and 114 and are located inside the upstream ends of the electrodes. The pair of electrodes 113 and the terminal 115 are integrally formed from the same metal to form a single member, as are the pair of electrodes 114 and the terminal 116. The electrodes 115i i 6 can pass through the holes on the bottom surface of the casing 110a to the outside of the bottom surface of the casing 11a. A water-tight seal 172 is provided at the terminals 115 and 116 penetrating the casing 110a, as shown in the attached figure. As shown in the figure, the watertight seal 172 and a second sleeve 175 (to be described later) can form a double seal structure to prevent water leakage therethrough. An insulation wall 173 that can isolate the terminals 115 and 116 from each other and the housing The bottom surface of ll〇a is integrally formed (see Fig. 6). Terminals 115 and 116 are connected by a cable (not shown 95732.doc -20-200523427) to the driving circuit i2 0 which belongs to the control section 80. Terminals 115, 116 The portion left inside the housing 110 may be protected by a sleeve made of an insulating material. There are two types used in this structure, including a first sleeve 174 and a second sleeve 175. The first sleeve 174 is composed of Made of synthetic resin, 2 surrounds and joins the bases of the terminals 115 and 116. The first sleeve 174 has a part extending on one side surface of the electrodes 113 and 114, and a protrusion is provided on the side of the part for joining Corresponding through holes on the electrodes 113, 114 (see Fig. 6 and Fig. 7). Prevent the electrodes 113, 114 from slipping out of the first sleeve Η. The second sleeve 175 is made of soft rubber and fills the gap between the first sleeve 174 and the bottom wall of the casing 110a to prevent water from The gap between the second sleeve 175 and the gap between the second sleeve 175 and the electrodes 113 and 114 is leaked.。 The terminals 115 and 116 are located upstream of the electrodes 113 and U4 and are used to support the electrodes 113, The support part of the upstream part of 114 includes the first sleeve 174 that is engaged with the terminals 115 and 116. A fork-shaped support part 176 is formed on the inner surface of the upper cover and matches the position of the first sleeve 174 (see (Figure 6). The support portion 176 can clamp the upper end of the first sleeve 174, and the second sleeve 175 can fill the gap between the first sleeve 174 and the housing 110a, and the two together form a stable Support structure. Note that the fork-shaped support part 176 sandwiches the electrodes 113 and 114 with their long and short protrusions, and fixes the distance between the electrodes 113 and 114 on the nob side of the upper cover in an appropriate manner. The electrodes 113 and U4 are located downstream The part is also supported by a support part provided on the inner surface of the casing 110. The fork-shaped support part 177 is The bottom wall of the housing 11a rises, and the fork-shaped supporting portion 178 hangs down in a similar manner from the top surface of the upper cover 11〇b 95732.doc -21-200523427 and faces the supporting portion 177 (see FIGS. 5 and 8). The lower and upper edges of the electrodes 113 and U4 are sandwiched between the supporting portions 177 and 178 to support the electrodes 113 and 114 so that they do not move. As shown in Fig. 7, the electrodes 113 and 114 are arranged. The method can form a space between the opposite surface of the opposite surface and the inner surface of the casing 110. As shown in FIG. 5, the arrangement of the electrodes 113 and 114 also forms a space between the upper and lower ends of the electrodes 113 and 114 (except the portions contacting the supporting portions 176, 177, and 178). In addition, as shown in Figs. 5 and 7, the electrodes 113, 114 also leave spaces between their upper and lower edges and the inner surface of the case 110, respectively. Note that if the width of the case 110 has to be reduced, the opposite surface of the opposite sides of the rhenium electrodes 113, 114 in the structure used closely contacts the inner surface of the case 丨 J 〇. In order to allow foreign matter to contact the electrodes 113, 114, a filter made of a metal mesh is provided upstream of the electrodes 113, 114. In this specific example, the filter 1 80 is provided in the connecting pipe 51, as shown in FIG. The filter 18 can prevent foreign matter from entering the water supply valve 50 ', and can also be used as a filter upstream of the ion dissolving unit ιOO. A metal mesh filter 181 is also provided downstream of the electrodes 113 and 114. The filter 181 can prevent the electrodes 11 3 and 114 from being thinned due to long-term use, and then broken into fragments and eventually flowing away. The filter 181 can be installed at the outlet 112 (for example) according to my choice. The installation positions of the filters 180 and 181 are not limited to the above-mentioned locations. The filters 18 and 181 can be set at any position in the water supply path, as long as these locations meet the requirements of "located upstream of the electrode" and "located downstream of the electrode". Please note that the filters 180 and 181 can be disassembled in order to remove the foreign matter they trapped, or to remove the materials that cause clogging 95732.doc -22- 200523427. The driving power of the ion dissolving unit 100 will be described below. FIG. 9 shows a configuration example of one of the driving circuits 120. A transformer 122 is connected to a commercial power source 121, and the transformer 122 can reduce 100 volts to a predetermined voltage. The output voltage of the transformer 122 can be rectified by a full-wave rectifier circuit 123, and then adjusted by a regulator 124 to a fixed voltage. A current stabilizer 125 is connected to the stable G 叩 124 Liuzhai 125, which can supply a fixed current to an electrode driving circuit 150 (described later in the valley) without being affected by the resistance change of the electrode driving circuit 1 $ 〇. A rectifying diode 126 is connected in parallel with the transformer 122 to a commercial power source 121. The output voltage of the rectified diode 126 can be smoothed by a capacitor 127, and then adjusted by a voltage regulator 128 to a fixed voltage, and then supplied to a microcomputer 130 ° microcomputer 130. It can start and control a bidirectional AC trigger triode. Up, the two-way AC triggering three-pole system is connected between one end of the main coil of the transformer 122 and the commercial power source 121. The structure of the electrode driving circuit 150 is that the NPN transistors Q1 to Q4, the diodes di and R1 to R7 are connected in a diagrammatic manner. The transistor Q1 and the diode D1 form an optical coupler 151, and the transistor Q2 and the diode D2 form an optical coupler 152. In other words, the diodes di and d2 are light-emitting diode 'transistors Q1 and Q2 are optoelectronic crystals. If a high voltage is applied to a line L1 and a low or zero voltage is applied to a line L2, the diode D2 will be activated accordingly, and the transistor Q2 will be activated accordingly. After the transistor Q2 is started, a current will pass through the resistors R3, R4, and R7, and a bias is applied to the base of the transistor Q3, so that the transistor Q3 is started. On the other hand, the diode D1 is in the off state. Therefore, the transistor Q1 95732.doc -23- 200523427 f is in the off state and the transistor 卩 4 will also be in the off state. In this state, the down-electrode will flow from the electrode 113 located on the anode side to the electrode U4 on the cathode side, so that metal ions (which are cations) and anions are generated in the ion dissolving unit _. "After passing through the ion dissolving unit 100 in a certain direction for a long time, the electrode 113 on the anode side in Fig. 9 will be lost, and the impurities in the water (such as about) will be stubbornly fixed on the On the cathode electrode Μ. The chloride and sulfide formed by the constituents of the electrode will appear on the surface of the electrode. The =-phenomenon will reduce the efficiency of the ion dissolving unit 100, so here is a specific example In the structure used, the 'electrode driving circuit' will reverse the polarity of these electrodes under our own operation. After reversing the polarity of the electrodes, the microcomputer 13 will switch the control mode and reverse the interval between the lines l1 # L2. The voltage will cause the current between the electrodes 113 and ιΐ4 to flow in reverse. Transistors Q1 and Q4 will be activated, while transistors 卩 2 and 卩 3 will be closed. The computer 130 has a -counter function. When the count value reaches a predetermined value, the control mode will be switched. When the resistance in the electrode driving circuit 150 (especially the resistance of the electrodes 113 and 114) changes, causing the amount of current between the electrodes to decrease, the regulator 125 will Increase its output voltage to prevent The flow decreases. However, when the accumulated usage time = plus time, the ion dissolving unit will eventually reach the end of its service life. At that time, even if the polarity of the electrode is reversed, the control mode is switched to an electrode cleaning mode (that is, extended by one Application time of specific polarity to forcibly remove impurities attached to another electrode) 'or to increase the output voltage of the current stabilizer 25, still cannot prevent the amount of current from decreasing. 95732.doc • 24 · 200523427 Therefore, in this circuit, I will use the potential difference between the two ends of the resistor R7 to monitor the current in the ion dissolution unit 100 and between the electrodes 113 and 114. When the current reaches a predetermined minimum current, a current detection circuit 160 can detect this phenomenon. The information that the minimum current has been detected will be transmitted from the light-emitting diode D3 (which is a part of an optical coupler 163) to a microcomputer 13 through a photoelectric crystal 卩 5 (which is a part of the optical coupler 163). Microcomputer 13〇 An alarm device 13 丨 can be driven through a line L3 to generate a predetermined alarm. The alarm device m is provided on the operation / display section 8 丨 or the control section 80. A fault condition such as a short circuit in the electrode driving circuit 15 is provided with a current detection circuit 161 which can detect whether a current exceeds a predetermined maximum value. When the electrode driving circuit 150 fails, the microcomputer 13 can detect based on the current The output of the circuit 161 drives the alarm 131. In addition, when the output voltage of the current stabilizer 125 falls below a predetermined minimum value, a voltage detection circuit 162 can detect this phenomenon, and the microcomputer 130 will similarly The alarm 131 is driven. The metal ions generated by the ion dissolving unit 100 will be sent into the washing drum 30 in the following manner to perform antibacterial treatment on the laundry. When the main water supply valve 50a is opened, the main water supply path 52a Water flows in the middle. If you want to supply a larger amount of water, you can open the secondary water supply valve 50b to make the water flow in the secondary water supply path 52b. In a metal ion dissolving step, water from the main water supply valve 50a will flow into the internal space of the ion dissolving unit 100 and fill the space. At the same time, the driving circuit 120 will apply a voltage between the electrodes 113 and 114 to dissolve the metal constituting the electrode in water in the form of metal ions. If the metal used to make the 95732.doc -25- 200523427 is a silver electrode, the electrode on the anode side will generate an Ag-Ag + + e reaction, so the electrode is dissolved in water as Ag + ions. The current between these electrodes is DC. The metal ion-added water will enter the cleaning agent chamber 54 and be injected into the cleaning drum 30 from the water injection port 54a through the water injection port%. 0 If a predetermined amount of metal ion-added water is to be supplied into the cleaning cylinder 30, The water can be injected into the predetermined portion and added with metal ions /

Wash the inside of the drum 30 and pour water without adding metal ions until a set water level is reached. When the metal ion concentration in the water in the cleaning drum 30 is judged to have reached a predetermined value, the control section 80 will follow a predetermined operation procedure 'fork-stop water supply processing, and then issue a signal, & stop at electrode 11 Action of applying voltage between 3 and 114.

"You can get the water flow rate even if the main program is used to produce metal ions in advance. The main water supply valve 5Ga will continue to supply water after the ion dissolution unit stops producing metal ions until the water supply reaches the threshold. The metal ions added to the water are brought to a predetermined concentration. ^ 13 114 The metal electrode will continue to dissolve into metal ions.

During the process, the amount of metal ions dissolved will gradually change to W 4 'Metal electrode. The amount of metal ions dissolved will be converted to unsatisfactory, or the ionless dissolution unit I have a solution that can solve the problem at the "end of departure" pair: a new pair of mines: the fact that the electrodes 113 and 114 have reached the end of their useful life can be replaced by =. In addition, the electrodes 113 and 114 are used by the operator For example, report the author to the author, and promote the exchange of the ion dissolution unit 100 as 95732.doc -26 · 200523427. After the ion / combination unit 1GG is driven, the steady current in the driving circuit i 2Q is stabilized. The device can control the current between the private poles 113 and 114, so that the amount of metal ions dissolved by the metal electrode in each unit time is constant. If the amount of metal ions dissolved by the metal electrode in each unit time The system is fixed, and we can control the water flow and ion dissolution time in the ion dissolution unit_ to control the metal ion concentration in the cleaning drum 30, so that the desired metal ion concentration can be easily reached. Please note that the electrodes 113 and 114 Steady flow The current induced by the US can change according to the water quality or temperature. The control method is described in detail below. Fouling is deposited on the electrodes 113 and 114 and used as one side of the cathode. If the direct current is continuously passed without Reversing the change of the deposition amount of Wang Dan's scale, it is difficult to circulate the electricity, causing the metal to be decomposed into metal ions. In addition, it is still the problem of converting to the anode electrode and consuming L. The cathode will soon reverse the polarity of the electrodes 113, 114 in a periodic manner. Word of mouth :: Γ Refer to FIG. 10 to explain-a control method used to apply electromigration between the electrodes 113 and m. Fig. 1G—The electrolysis soil dissolving step ti 、, Tian t is not described in the separation of five people if you choose: Second turn operation decomposition action. For example, in the final rinsing step (there is a washing burdock — β step, and — dehydration step), select “injection of metal ^ Α ^ first step and the final rinsing step is the ion rhenium step.” The function is shown in the figure. First, the main water supply valve 50a and the secondary start drive circuit 12 must be opened; the long-time valve 50, and this is not there yet—electrode A (electric 95732.doc -27- 200523427) A voltage is applied between one of the electrodes 113 and 114 and an electric power (the other electrode of the electrodes 113 and li4). In this state, we can confirm the operation of the current detection circuits 160 and 161, so as to prevent the current detection circuits 160 and 161 from performing an incorrect detection operation, resulting in an error in the concentration of metal ions dissolved by the metal electrode. After the operation confirmation of the current measurement circuits 160 and 161 is completed within the operation confirmation time T1 of the current measurement circuit, the supply of current between the electrodes eight and 6 can be started. Baixian applied a voltage to the electrode A, and made the voltage depend on the ground. At this time, the function of the electrode A is an anode, and the function of the electrode B is a cathode. After the -voltage application time has passed 2, do you stop applying electricity to the electrode money? Then start to apply to the electrode B-electricity I-interspersed between them-the time of electric application suspension T3. Electrode A remains at ground voltage. At this time, the function of the electrode b is an anode, and the function of the electrode A is a cathode. In other words, the polarity of ㈣ between the electrodes has been reversed. After the -voltage application time has passed 2 again, the application of electric dust to electrode B is stopped; the polarity of the voltage between these electrodes is reversed again; a voltage application pause time T3 is interposed therebetween. The voltage application time T2 and the voltage application pause date 13 are alternately repeated in this manner, and the polarity of the voltage between the electrodes 113 and 114 is reversed in a periodic manner. The action of reversing the polarity will be repeated until the metal electrode dissolves a predetermined amount of metal ions. The application time of the electric voltage and the suspension of the application of the voltage were defined as the sum of the T3 between the daytime and the hour as the "ion dissolution time" D4. In order to read that our people can control the effective dissolution rate of metal electrodes into metal ions, the inventors have found after research that if we want to ensure the dissolution efficiency of a metal electrode 95732.doc -28- 200523427 and make the electrode uniform The optimal value of the loss is as follows: The voltage application time T2 is 19.9 seconds, and the voltage application pause time D3 is 0.01 seconds. It has also been found that the voltage is preferably about 10 volts and the current is preferably about 29 milliamps. In addition, it has been found that in order for the antibacterial treatment applied by me to meet the antibacterial properties specified in JIS (Japanese Industrial Standard) L 1902, the silver ion concentration must reach about 90 ppb ° I am a washing machine with a rated laundry capacity of 8 kg Put 8 kg of simulated laundry as specified in JIS C 9606 (washing machine), and install an ion dissolving unit controlled by the aforementioned optimal value in the washing machine, and then use JIS L 1902 (Fabric Antibacterial and Antibacterial The test method for the effect) of the bacterial liquid absorption method (antibacterial / deodorizing surface treatment with a bacteriostatic activity value of 20 or more) When an antibacterial test was performed, the bacteriostatic activity value was 2.4. If 8 kg of laundry is washed once a day and antibacterial treatment is applied (40 liters of water in each antibacterial treatment), the service life of a pair of silver electrodes weighing υ gram can be as long as ⑺ years. The results of an accelerated dissolution test (continuous dissolution of silver into silver ions) were confirmed. I can tell from these results that using the minimum amount of silver electrodes necessary can make full use of the service life of a washing machine and provide sufficient antibacterial effect to the laundry during this service life. In the present invention, water is supplied to the ion dissolving unit 100 before the voltage is applied to the electrodes 113 and 114. In this way, it can be ensured that the metal electrode can be dissolved into metal ions when we first apply a voltage to the electrode, thereby ensuring that the total amount of metal ions applied to the clothes meets our needs. The current detection circuits 160 and 161 do not detect until the voltage is applied to the electrodes 113 and 114 and a predetermined period of time has elapsed. This detection operation 95732-do, -29- 200523427 will continue to monitor the current between electrodes 113 and 114 until the ion dissolution time τ4 ends. The detection results of the current measuring circuits 160 and 161 are the basis for controlling the driving circuit 120. Therefore, any one of the current detection circuits 16 and 161 will not detect when we first apply voltage to the electrodes 113 and 114 and the current is still unstable. We need to wait for the current to stabilize before starting 2 To ensure that the detection operation has high accuracy. When the electric detection circuits 160 and 161 detect a constant electricity that is beyond a predetermined range, the 'alarm nm will inform this — phenomenon' allows the operator to know that the ions dissolve as early as possible. Το 1〇 will not be able to ensure the required The ion dissolving amount, and the required antibacterial treatment cannot be performed on the laundry; the ion dissolving unit 100 must be adjusted or repaired. When abnormal current values are measured by the current detection circuits 160 and 161, the washing machine "quotes stop running" This pause operation can prevent the washing machine worker from losing the function of antibacterial treatment of the first clothes (the original was The ion dissolving unit 提 should be mentioned t)) and the operation of the Tochigi writer was continued without the knowledge. The following operations can also be used: # t +. W ^. That is to say, in this operation mode, even if the current detection circuit 1 60, 16 b, and 丨 γ s A & a "Electricity, 々, L value of a book, as long as it has been detected in the ion dissolution step At least once a person stops the current of the magnitude, the alarm 131 will not notify the abnormal situation. The right wiper uses this mode of operation, even if the price side is wrong due to noise or similar factors, resulting in an abnormal situation measured temporarily. : The washing machine 1 will continue to run to complete the washing step. The machine ^ drives the ion dissolving unit 以 in a '? Way. First, adjust the ion dissolution time T4 according to the washing water (that is, according to the water level in the cleaning drum 30). So—Shi Cai, because the ion dissolution time Ding 4 is adjusted according to the water consumption 95732.doc 200523427, the water supplied to the laundry will have a stable metal ion concentration, which will not be contrary to the wishes, so that the laundry will be metal ion concentration Excessively high water is used for dyeing, or sufficient antibacterial treatment is not obtained because the metal concentration is too low. Voltage application time T2 and voltage application suspension day-to-day T3 applied to electrodes 113 and 114 It will be further adjusted according to the amount of water or the ion dissolution time D4. We can adjust at least one of the voltage application time T2 and the voltage application pause time T3 by this adjustment action to compensate for the electrode 113 or 114 due to water or The amount of dissolution of the metal electrode changed due to the ion dissolution time T4. In this way, both the electrodes 113 and 114 can be uniformly consumed, and one of the electrodes 113 and 114 can be prevented from using one-sided polarity and used as a cathode for longer than When used as an anode, a large amount of scale was deposited on the electrode, which caused the electrode to be reversed to the anode, which hindered the effect of dissolving the metal electrode into metal ions. By this method, we can carry out long-term laundry washing. Stable antibacterial treatment. The voltage application time, the voltage application pause time T3, or the ion dissolution time D4 applied to the electrodes 113 and 114 will be further adjusted according to the flow detection result of the flow detector 185. If the water of the washing machine 1 is used, The method is to connect to the tap of the tap water, then the operating conditions such as water pressure and pipeline resistance will vary from household to household; The opening percentage of the water supply valve 50 on the machine! Side is fixed, and the flow rate of water flowing into the ion dissolving unit 1⑻ is still non-quantitative. If the above adjustment can be made based on the flow detection result of the flow debt detector 185, you can rely on water The flow rate adjusts the amount of metal ions dissolved by the metal electrode, reducing the fluctuation range of the metal ion concentration in the water supply, so that the laundry is subjected to the antibacterial treatment of the uniform sentence. In this way, it is possible to save one to disperse the metal ions to the Stirring steps for various parts of laundry. 95732.doc -31 · 200523427 When the current detection circuit! 60 rounds, see the current value between Dongji 113 and 114 is less than or equal to-predetermined value. t Ding Gejie's 100% reduction in the flow of water, and the ion dissolution time, that is ... 'will be extended. If this operation method is used, even if the current is not enough to ensure that once the Furenwu A ”is required for the metal ions dissolved by the electrode (that is, when the -metal electrode is less likely to dissolve into all ions), the -electrode can still Through f to resolve the metal county from the early Fensi Shi M long water time (due to the decrease in flow) and the extension of water two / room, etc., dissolve the predetermined amount of metal ions, until U Fan,. '、 止' The laundry can always obtain a stable antibacterial treatment. The following will explain how to change the electrode's dissolution into metal ions, and then make it & according to the water f or water temperature. This procedure is a feature of the present invention. Generally speaking, the water used in the washing machine is tap water, and it is compatible with drinking water. Therefore, the water quality will vary greatly depending on the region. In theory, we can deduce the efficiency of dissolving metal electrodes into metal ions in the following ways: And the mouth 'silver will become a monovalent silver ion after the solution, so if you supply a current of 29 milliamps for 2 minutes' and add the silver ion-the capacity is 40 kilometers ^ π Washing the drum 3G, I can according to Faraday The law of electrolysis establishes the following relational concentration) = (Atomic weight of silver: 10.78.68) χ (the amount of current between the electrodes ·· / ¾A) X (A solution time: 120 seconds Faraday constant: 96485 coulombs / mol ) / (Water volume: 40 liters) = 97.3 ppb.; ,,; And, after 5 weeks of investigation and measurement of the dissolution efficiency in various parts of Japan, it was found that, for example, the dissolution rate of 'hawker, metropolis, and Tokyo is about It is in the range of 80% to 90%, but the value of a certain place in Ryukyu has dropped sharply to about 30%. The conclusion is that the change in water shell will greatly change the dissolution efficiency. When the water temperature is different, the dissolution 95732.doc- 32- 200523427 Zhang rate said something different @ 'But there will not be a huge difference caused by water quality. In order to perform stable anti-g treatment on the laundry, water with a predetermined metal ion concentration must be stably supplied to the cleaning drum 3 0. Size 'and change the amount of dissolution in each unit time; Another method is to change the time that the motor passes through the electrodes 113, 114 (the ion dissolution time τ4 in Figure 10). Current of 125-set current value can be changed according to water shell or water temperature By changing the current between the electrode ΐ3 and :: make up-the metal electrode dissolves in the metal electrode due to the change in the dissolution efficiency, and supplies water with a predetermined metal ion concentration to the cleaning drum. Ion dissolution time. If the current and ion dissolution time are changed at the same time, it will increase-change the degree of freedom. In addition, each change amount is relatively small even if the dissolution efficiency changes greatly. Therefore, the "current increase is not large" can ensure Margin relative to the threshold value of the circuit components. This is a better method in terms of the safety of the washing machine. The washing machine has a primary flow rate detector 185, which can be used to measure the water flow rate. Therefore, we can use the flow rate information , Decide how to change the current target value and ion dissolution time for control, and M can complete the operation of dissolving the metal electrode into metal ions until the water supply is completed. Please note that the step of dissolving the metal electrode into a metal ion can also be added after the water supply operation in the initial stage is completed. In the washing machine 1, the flow stabilizer! 25 can change the voltage applied between the electrodes 113 and 114 so that a current of -solid magnitude passes through the electrodes U3 and u4. Although the water quality will change the dissolution efficiency, the water supplied to the cleaning drum 30 will not change drastically during the water supply process, and the dissolution efficiency will not change during the same period. 95732.doc -33- 200523427, and the metal electrode The reaction of dissolving into metal ions (Ag ~ Ag + + ej is also fixed. Therefore, if a fixed current value is used, it will be easier to calculate the amount of metal ions dissolved by the iso-metal electrode, and it is easier to calculate the target current value And voltage application time. The action of applying electricity between the electrodes is performed in the sequence shown in Figure 1G. If the electric application time T2 and the voltage application pause time D3 are provided in this way, we can change the ion dissolution time without changing Under the circumstances, change the time available for the metal of an electrode to dissolve into metal ions (for example). In this way, it can be controlled-the behavior of the metal electrode dissolving into metal ions to respond to changes in water quality: during the cleaning process The water in the cleaning drum 30 contains a large amount of cleaning agents, pollutants, and other substances. In order to prevent the electrodes 113 and 114 from being used again in this k, we use it. The structure system installs the ion dissolving unit 100 in the water supply path. Therefore, one of the above methods can also be adopted, that is, the ion dissolving time is adjusted by “week gp t, water flow 1”, and the king ’s ion is added. Until the water supply is complete. However, in terms of operability, if an operating procedure similar to the above control method is used, that is, the electric application time and the voltage application pause time T3 are changed to constitute the ion dissolution time, or both. For the 'by adjusting—the metal ions dissolved by the metal electrode', I only need to choose a way to adjust the time, and I can add a predetermined amount of metal ions until the water supply is completed; compared to the water supply time car: long, and It is necessary to adjust the flow of water supply at the same time. The above operation procedure is more suitable for the purpose of adding a predetermined amount of metal ions, and it is helpful to implement the antibacterial treatment performed by the operator 2. In addition, it is not necessary to use M $ adjustment in this operation procedure. The device reduces costs in this way. 95732.doc -34- 200523427 In the present invention, it is better to change the voltage application time T2 and the voltage application pause Time T3 without changing the polarity reversal period (the sum of the voltage application time T2 and the voltage application pause time T3). If this is taken into consideration, the dissolution of a metal electrode into metal ions will It can be carried out in the same cycle as the design stage, so as not to cause a single electrode to be severely depleted due to changing the voltage application time τ2, resulting in insufficient dissolution amount, reaching the end of the service life early, or causing the dissolution amount to be inconvenient, for example. For example, I want to dissolve a metal electrode with a predetermined amount of metal ions within 2 minutes, and the initial setting value of the voltage application time D2 is 10 seconds, and the voltage application pause time T3 is 10 seconds. The water quality is changed and reduced to two thirds of the target value. We can set the voltage application time T2 to M seconds and set the voltage application pause time T3 to 5 seconds. In this way, it is possible to dissolve a metal electrode without changing the voltage application cycle of 20 seconds: the amount of metal ions is set to one and a half, so that the amount of metal ions dissolved in a metal electrode reaches the target value, and the operator To achieve the required antibacterial treatment. We can change one or both of the voltage application time T2 and the voltage application pause time T3 according to a target current value. When using this method, we can set a time for a target current value to dissolve a metal electrode into metal ions to prevent the metal electrode from over-dissolving into metal ions when the target current value is set high (for example) In addition, the electrodes 11; 3, ιΐ4 reach the end of the service life earlier, and the laundry is exposed to metal ions, and is dyed, causing inconvenience. I can use the voltage detection circuit 162 to detect the voltage between the electrodes 13 and 14 to detect the water quality and temperature. This is due to changes in water quality (that is, changes in hardness, transparency, 95732.doc -35- 200523427, or similar properties) will change the conductivity coefficient of water; and changes in temperature will also slightly change the conductivity coefficient. We can calculate the conductivity coefficient from the target current value and the applied voltage to measure the water quality and temperature.

Incidentally, if the difference in water quality is defined by the conductivity coefficient, a higher conductivity coefficient will reduce the dissolution efficiency. This phenomenon has been confirmed. In other words, the voltage will decrease as the conductivity increases. Since the conductivity is usually in the range of H) 0 to 300 micro-Simens / cm ("/ La), if the reference value of the conductivity is set to _micro-Simens / cm (for example),-once it exceeds this conductivity For reference values, it is best to implement the control method as described below to improve the efficiency of dissolving a metal electrode into metal ions. The conductivity of the two knives 'because the water temperature is higher' tends to be higher. It is necessary, and the influence caused by the rising water temperature needs to be considered, that is, the higher the water temperature, the lower the dissolution efficiency. In other words, as the water temperature is higher, the electricity of 1 ° [the smaller the current and the lower the water temperature The electricity between the electrodes is often more than two, so when the water temperature exceeds a predetermined temperature reference value, it is best to perform

The control method described below is to improve the efficiency of dissolving metal electrodes into gold. It has been induced between the electrodes—predetermined size H and the voltage is ~ electrical material. It is best to implement the control method as described below. The efficiency of dissolving a metal electrode into a metal ion 4 and w 卞 rather than adjusting the conductivity system 〆 / dish again. M> idea, when the actual values of M and W are above the conductivity coefficient reference value or the reference value of ▲ degrees, or much higher than the table 7-8F, the voltage is kept at a low level, a metal electrode is dissolved to belong to the ion Efficiency will be too high, efficiency control method. It is best to perform-can reduce the solution 95732.doc -36- 200523427 The relationship between the rapid pressure and the efficiency of the solution is shown in Figure 丨 丨 (to be described later), and it is best to control the voltage applied between the electrodes. The efficiency of dissolving metal electrodes into metal ions is maintained in the range of 70% to 100%. In order to make the bacteriostatic activity value exceed 2 · 0 (the result of the aforementioned 181 ^ 1902 antibacterial test), and to exert the life of the silver electrode, if the applied voltage can be controlled within the range of about 7 to 17 volts, It is better to maintain the efficiency of dissolving a metal electrode into metal ions in the range of 70% to 90%. Based on the survey results of water in various places in Japan, I found that, as stated, the efficiency of dissolving metal electrodes into metal ions is extremely low in a certain place in Ryukyu. After further investigation, it was further found that application to electrodes The voltage is extremely low. For example, in Osaka, a voltage used to induce a current of 29 milliamps between electrodes ιΐ3 and ιΐ4 is about 10 volts, but in the area of Ryukyu, the voltage is about 4 volts; in Osaka, the dissolution efficiency is about 80. %, But the dissolution efficiency in this area of Ryukyu is about 30% (both relative to the theoretical dissolution amount derived from the law of Faraday's electrolysis). Therefore, my research was carried out with water taken from Osaka, and the result was: for example, 'if a current of _29 milliamps is induced between the silver electrodes 113 and 114, that is, the relationship between the voltage applied by H and the dissolution efficiency, such as Figure U. Figure u shows that the relationship between voltage and bathing efficiency is within the range of the applied voltage. It is not that the lower the voltage, the lower the dissolution efficiency, and the dissolution efficiency drops sharply when the electricity C is equal to or lower than 7 volts. I have found that when the dissolution efficiency is almost zero, 'the voltage is slightly larger than volts' and the metal electrode will not dissolve into metal ions unless a voltage having a value greater than or equal to the value is applied. This relationship has a high correlation with the results obtained in a place in Ryukyu (wherein in Ryukyu, when the electricity 95732.doc -37- 200523427 I is about 4 volts and the current is 29 mA, the dissolution efficiency in water is about 3 0 /., Its value is very low), indicating that changes in water quality can be measured by voltage. Please note that in this specific example, we use the voltage of electrodes 113, 114 to dissolve a metal electrode into metal ions, and no additional components are required. We can set up another electrode for detecting water quality, because it can increase the detection position, it's really a better method. For example, the used electrodes and terminals can be installed in the drainage space 66 (the water in the cleaning drum 300 enters it), the water drum 20, or the vicinity of the cleaning drum 30.

A metal electrode can be dissolved into metal ions under our control, so as to change the dissolution efficiency due to water quality. Among them, our control method is to change the target current value, voltage application time T2, and voltage application based on the pressure detection value. Stop time T3, ion dissolution time T4, and other items.

When the voltage detection value is less than the predetermined voltage, we can change the control method of the counter electrodes 113_, 114 to improve the metal Zheng dissolved by the metal electrode! . In other words, we can increase the target current value, prolong the application time T2 and ion dissolution time, and shorten the voltage application pause time, thereby increasing the amount of metal ions dissolved by a metal electrode. For example, in the past, ^ electric power is greater than-duty value (such as 7 volts), we can change the application time of electric power in the case of the target current value: ::: (for example) to adjust the- The amount of metal ions. However, if the voltage is less than the predetermined value = 2: changing the application time of the voltage, the target current can also be changed at the same time. The total ionization is 42 milliamps "so as to adjust-the amount of metal dissolved by the metal electrode = amount. Please note that when the voltage is greater than the predetermined voltage, it will also decrease the amount of metal ions dissolved by the electrode, and we can regard it as the control method of 95732.doc -38- 200523427. / JEL degree can be directly measured by a water temperature detector (such as an installed thermistor). The water temperature detecting device can be installed inside the ion dissolving unit 100 (upper and downstream), or in a water drum 20, a cleaning drum 30, or a peripheral area located further away. Basically, the temperature is closely related to the water temperature, and I can infer the environment at that time from the water temperature measured by the water temperature. Therefore, I can lower the water temperature (that is, the air temperature) during the year and cause the laundry to finish. Increase the metal ion concentration during the period when it is not easy to dry. It is best that the operator can select items that need to be changed and do not need to be changed in the target current value, ion dissolution time T4, voltage application time T2, & voltage application pause time T3 to match the water quality or water temperature. In areas where the dissolution efficiency of clear water is low (such as somewhere in Ryukyu), it is best to change the target current value, ion dissolution time, voltage application time, or voltage application pause time each time to make it different from the individual standard value. However, it is not necessary to change in areas with standard water solubility. Even in areas with standard dissolution efficiency, the operator can use the remaining water of the Japanese-style bathtub to save water. In this case, changes in water quality and temperature will change the dissolution efficiency ', so the above changes need to be made to obtain the desired antibacterial effect. Since the water temperature varies greatly with the season, standard values such as the target current value set according to the water temperature in the spring and autumn (for example) should be modified in summer or winter. If the operator can issue an instruction on whether to change a certain item, the desired antibacterial effect can be achieved regardless of the season of water & To achieve this-the purpose 'is just to install an order changer in the operation / display section. 95732.doc -39- 200523427 I can adopt a structure, in which the washing machine 2 itself can also change the target current value or similar items, and set it according to the detection results of water quality and temperature-the target current value or Its a similar project. In the implementation manner, the control part 80 operates the voltage detection circuit 162 and the above-mentioned water temperature detector according to the action of a switch, thereby detecting the water quality and water temperature, and calculating the target temperature, the ion dissolution time T4, and the electricity M Appropriate values of the application time T2 and the electric application pause time T3.

The operator can set at least one of the target temperature, ion dissolution time T4, electromechanical application tear T2, and electric repeated application pause time D3. For example, in operation. ρ knife 8 1 in. There is also a selection switch for selecting a value (such as the target current value or a similar value), and the operator can operate the selection switch at the beginning of washing, and can also be operated in the operation / display section 8 i, the control section 80, and A selection switch, a selection connector, and a selection jumper are installed in the driving circuit 120 to change the setting value.

If the operator can set a current value of M votes or similar items, it is recommended to install in the control section 80-electronic erasable programmable read-only memory to: remember the changed target current value or similar value, its sequence Sequence and change == system 1 uses this structure, so you don't need to use the washing machine every time: perform the set action. If you can use one of the electronic simple operation modes' 刼 Control operation / display part 81 of a predetermined switch, 俾 Enter = Mode 'and operate a selection switch' to change—the control program will change again. You can easily change the setting value. : Note 'can also adopt a structure in which the manufacturer, installer, or operator can enter the information of the installation location on the washing machine (that is, environmental conditions, such as 95732.doc -40- 200523427 installation water area information), rather than directly Set the target current value or similar items and change the control sequence of Ai Washing Machine 1. Washing machine] itself can also use gps (full dislocation system) information or network f news to learn about environmental conditions, so as to change the control type.刼 The author can indicate whether to use clear water or the remaining water of the Japanese-style bathtub; if using the remaining water of the Japanese-style bathtub ', it can also be controlled by using the memorized value or the changed program. In a specific example, the washing machine may adopt a structure in which the voltage between the electrodes ii3 and 114b is detected by the voltage detection circuit 162, and the water quality is detected, but the measured water quality is not the water quality in the cleaning drum 30. The water quality in the ion dissolving unit 100. In many cases, we will also add a surface treatment agent in a step of ordering antibacterial treatment, which surface treatment agent may greatly change the water quality. Therefore, after adding a surface treatment agent, the water quality measured by the voltage will be different from the water quality in the cleaning drum 30, and thus it may not be able to produce a sufficient antibacterial effect. To avoid this inconvenience, a water quality detector 187 can be installed in the cleaning drum 30 or the drainage space 66 which is in communication with the cleaning drum. The detector is different from the electrodes 113, 114 and the voltage detection circuit ι62. combination. The main purpose of the water quality detector 187 is to determine the presence or absence of a surface treatment agent. Therefore, the detector can be a simple structure that can only achieve this purpose. For example, after adding a surface treatment agent, the transmittance of water will change accordingly. This phenomenon can be used as one of the sensing items for measuring transmittance. Once I find that the surface treatment agent has been added, I can adjust the amount of metal ions dissolved by the metal electrode, or after completing the initial stage of the water supply operation (in which metal ions have been added), add another containing an appropriate amount of metal ions (as a solute). Water to ensure the desired antibacterial effect. Please note 95732.doc -41-200523427 思 ’This leech debt detector can be installed in the surface treatment agent compartment 5 5. If the basis for changing the target current value or similar value is the water quality of the water supplied to the cleaning drum 30 without passing through the ion dissolving unit 100 (for example, the remaining water of a Japanese bathtub is injected by a pump), this should be used to detect the cleaning drum Water quality detector 1 87 with water quality within 30 will be indispensable. In this case, the water quality detector 187 may also be a simple detector for measuring light transmittance. The above specific example is a fully automatic washing machine as an example, but the present invention can be applied to any type of washing machine, such as a horizontal drum type (drum type), an inclined drum type, a drying model, or a double drum type and other types. . The concept of "adjusting the amount of metal ions dissolved by a metal electrode according to water shell or water temperature" of the present invention is not only applicable to a structure that can generate metal ions by dissolving a metal electrode, but also a method that can make a metal containing A structure in which a component generates metal ions in a dissolved manner. It is clear from the above description that we can make various modifications and changes according to the present invention. Therefore, it should be understood that the present invention can be implemented within the scope of the attached patent application but is not limited to these specific descriptions.
