A tube and conductive members 512, 5136 M359667 are matched with different sizes of chambers to improve the efficiency of heating, and therefore are not limited to the description of the embodiment. After entering the tubular body 511 by water, the first The two conductive members 513 and 513 form electrical conduction to generate an electric field, and the electric field heats the water to raise the temperature of the water, and the first and second separating members 5i4 and 5i5 are disposed at both ends of the tubular body 511, and The charged water is formed in the electric field, and flows through the conductive sheet 517 to make the electrical properties of the liquid By contacting the conductive sheets 517, the electrical properties are transmitted to the joint portions 516, and then directed to the grounding end to achieve the effect of removing water and liquid electricity. It is particularly worth mentioning that when the liquid is liquid In the electric field, due to electromagnetism, the water molecules in the water liquid are magnetized, the structure of the water molecules is changed, and the large water molecules are magnetized by electric shock into smaller water molecules and magnetized. Because the water molecules become smaller, it is not easy to have limestone and other impurities in the chamber η of the water tank 2, and the flow of the water liquid is improved, thereby improving the overall heating of the new energy storage type electric water heater. The pump 6 is disposed outside the water storage tank 2 and has a water inlet end 61 and an outlet X and 62, and the water inlet end 61 is a water delivery line 2 and a chamber of the water storage tank 2 21 is connected, and the water outlet 62 is in communication with the first separating member 514 of the heating device 51. The control unit 7 is disposed outside the water storage tank 2 and controls the water storage tank after being energized. The liquid water in the chamber 21 is quantitatively outputted at a constant temperature, and the water liquid is prevented from being monitored. A leakage current is generated. As shown in FIG. 2, a first and a second electromagnetic valve 72, 73 electrically connected to the control unit 7 are respectively disposed on the water inlet pipe 3 and the water outlet pipe 4, and the control unit 7 detects the leakage. When there is too much water in the chamber μ 7 M359667 of the water storage tank 2, that is, the first solenoid valve 72' is closed by the control of the control unit 7 to stop the water tanker from the water inlet wheel. When the control unit 7 detects that the water in the chamber 21 of the water storage tank 2 is too small, the control unit 7 (5) can also use the first electromagnetic valve η to enable the external water to pass through. The inlet pipe 3 is input into the chamber 21, and when the control unit 7 detects that the temperature of the water in the chamber 21 reaches a predetermined set temperature, the second solenoid valve 72 is opened to make the hot water The outlet pipe 4 is pulled out to provide the user with the effect of quantitatively controlling the water liquid, and the predetermined temperature range can be set according to the user's demand. The predetermined temperature in the embodiment is 50 thief. In addition, when the control unit 7 detects that the water is charged, the power is cut off immediately, so that the heating device 5 1 Stop operation to prevent leakage. It is explained that the setting position of the control unit 7 can be configured according to the convenience of the designer and the user, and the measurement and control technology of the control unit 7 and the setting position thereof are those who are familiar with the electric heating related technology. The technology that can be easily understood and used by the second is not the focus of this embodiment, so it will not be explained in detail here. When the energy storage type electric water heater of the present invention is used, the water liquid is stored into the chamber 21 of the water storage tank 2 through the water inlet pipe 3, and is stored by the water pump 6, so that the water liquid is discharged from the water supply line 2 After entering the water inlet end of the water pump 6, the water is sent from the water outlet end 62 of the water pump 6 to the heating device 51, and the water liquid passes through the first separating member 514 and enters the tubular body 511. After the water liquid contacts the first and second conductive members 5 12 and 513 and forms an electrical conduction %' generating electric field' and the water liquid is heated by the electric field and forms a charged state, the M359667 passes through the second separating member 5i5 to make the water liquid When passing through the conductive sheets, the electrical properties in the water liquid are eliminated, and then the water liquid passes through the chamber 2 of the water storage, and the weight of the cold water is heavier than that of the hot water: The liquid stays at a high place in the chamber and forces the water with a low water temperature to flow to the bottom of each chamber 21, so that the water can quickly enter the heating device, and then the water is again subjected to water | In order to enter the water spring 6 and the heating device 51 'and enter the circulation path of the person to heat the water, so that the water Continually heated by the heating device 51 'so that the water temperature rise when liquid water liquid reaches the predetermined temperature, the second solenoid valve 72 by opening the outlet pipe 4, the water to flow out, for the user to use. With the above design, the energy storage type electric water heater of the present invention has the advantages of rapidly providing hot water and shortening the heating time, thereby effectively saving power; as shown in FIG. 2, the volume of the tubular body 511 of the heating device 51 is much smaller than that. The volume of the water storage tank 2 is 21 to 21, so that when the water liquid enters the s-shaped body 511 of the heating device 51, the water in the tubular body 5 is started to be hot, and due to the volume of the tubular body 511. It is much smaller than the volume of the chamber 21 of the water storage tank 2, so that only the water in the tubular body 511 needs to be heated during the heating process, without constantly heating the water in the entire chamber 21, so The heated water is quickly supplied in a short time, and the predetermined outlet temperature is quickly reached, thereby achieving the effect of rapid water supply. The energy calculation of the new energy storage type electric water heater is carried out. When the 3 liters of water is heated from 2CTC to (4), the required heat needs to be referred to as Leica, and the new energy storage type electric water heater is utilized. When the heating device 51 is heated under the same conditions, when the heating device 51 provides i kilowatts of electrical work, the heat generated by the M359667 has a U30 Leica' equivalent to heating 3 (10) liters of water: 1: 1 〇 6 degrees The electric power, therefore, compared with the conventional twisting state, the heating device of the new energy storage electric water heater can have (Μ=f3.9) 23% power saving efficiency. Therefore, the new type of storage Energy type = water device does have the advantage of saving electricity. ', ', ^, the role of the 'Lyley water pump 6', the water is continuously sent from the water storage tank 2 to the second body of the heating device 5, and the first and second conductive After the pieces 512, 513 are electrically connected to the water and liquid, the water liquid is continuously heated, and the heated water (4) is returned from the return pipe 52 of the heating unit 5 to the chamber 21 of the water storage tank 2 to form a hot water circulation. The purpose of rapidly heating the water liquid is to achieve the purpose of the present invention. However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto. The simple equivalent changes and modifications made by the scope of the patent and the new description are still within the scope of this new patent.
