DETAILED DESCRIPTION

[0029] A basic structure and a basic working principle of an embodiment are described below in combination with embodiment 1 and drawing 1.

Embodiment 1

[0030] As shown in FIG. 1A, a multifunctional membraneless boiled water electrolysis machine comprises: a container 21 for containing water; a container cover 20, wherein 22 is a water level indicating line; an electric heater 15 capable of heating or boiling water; an electrolysis power supply 9; and an electrolytic cell 10 with a water inlet and a water outlet. An electrolytic cell partition plate 11 divides the electrolytic cell into an electrolysis electrode assembly region 18 and an electrolytic cell water outlet region 19. An electrolysis electrode assembly 18 for electrolyzing water is mounted in the electrolytic cell (see FIG. 1B and relevant description thereof for details about an internal structure). The water in the container 21 can be pumped into an electrolysis water tank 17 and the electrolytic cell 10 by an electric pump 24 through a water outlet pipe 25 at a bottom of the container and a water outlet pipe 23 of the electric pump. An electric heater 16 is mounted at a vertical part of a pipeline 23. The water enters the electrolysis water tank 17 and the electrolytic cell 18 from a water inlet 15 (formed in the top of the water pipeline 23) of the electrolysis water tank 17 after being heated (capable of being controlled without being heated). The electrolyzed water flows from the upper part of the electrolytic cell into the electrolytic cell water outlet region 19 and flows from the water outlet of the electrolysis water tank 17 i.e., an apparatus water outlet 12. Wires 6 and 7 connect electrolysis power supply output to different electrodes of the electrolysis electrode assembly. The electrolysis electrode assembly in the drawing adopts a technical solution of membraneless water electrolysis with high efficiency so as to achieve certain water electrolysis indexes. See FIG. 1B and a description thereof for details.

[0031] FIG. 1B is an internal structure and an associated portion of an electrolysis assembly 18 (comprising an electrolytic cell and an electrolysis electrode assembly). Portions described in FIG. 1A are not mentioned again. 10 is an electrolytic cell, and 8 is an electrolytic cell wall. The water from the pipeline 23 enters a space 26 through the water inlet 15 in the lower part of the electrolysis water tank 17, and the space 26 is isolated by a sealing ring 29 and is not directly communicated with other spaces of the electrolysis water tank 17, so that the water can enter a lower space 11 of the electrolytic cell 10 only and is electrolyzed by the electrolysis electrodes 1 and 2, a gap 3 and a gap 4. The electrolyzed water flows out of the upper parts of the gap 3 and the gap 4, enters an upper space 12 of the electrolytic cell 10, then flows out of the upper part of the electrolytic cell wall, enters the electrolysis water tank 17, flows over a water storage baffle plate 27 to flow into a water outlet region 19 of the electrolysis water tank 17 after the stored water exceeds a water level line 5, and flows out of the apparatus water outlet 28 for use.

[0032] In FIG. 1B, the electrolysis electrode assembly is formed by two electrodes 1 and 2 of different polarities. The electrode 1 is has a shape of a cylindrical hole. Three cylindrical holes are schematically drawn in the drawing. The cylindrical holes are mechanically fixed; hole walls are mutually electrically connected with one another to form the electrode 1, and the electrode 1 is connected with the electrolysis power supply 9 through the wire 7. The electrode 2 is cylindrical. Three columns are schematically drawn in the drawing. The columns are mechanically fixed and mutually electrically connected with one another to form the electrode 2, and the electrode 2 is connected with the electrolysis power supply 9 through the wire 6. 1 can be correspondingly inserted with 2, each column of the cylindrical electrode 2 can be inserted into the corresponding hole of the cylindrical holed shaped electrode 1, and an electrolysis gap 3 is left between the cylindrical surface and the holed surface and is in a tube shape. Three gaps 3 formed by the three cylindrical electrodes and the three holed electrodes are schematically drawn in FIG. 1B. The spacing of each gap can be selected within a certain range as required, for example, in a range smaller than 5 mm to greater than 0 mm. When necessary, the spacing of the gap 3 can take a smaller value, for example, smaller than 1 mm to greater than 0 mm for intensifying the electrolysis effect of the water and the impurities in the water. Higher water electrolysis efficiency and indexes can be acquired when the apparatus needs to electrolyze raw water with low conductivity, such as purified water, distilled water and the like. Under the condition that the electrode gap is fixed, the probability and the quantity of the impurities and the water molecules electrolyzed are in direct proportion to the area of the gaps. Therefore, maximization of area of the gap 3 can increase the electrolysis efficiency. In FIG. 1B, the electrolytic cell wall 8 is a material suitable for being used as the electrolysis electrode, is connected with the electrolysis power supply through the wire 7 to become a portion of the electrode 2 and forms an electrolysis gap 4 with the electrode 1, thereby increasing the electrolysis effect of the apparatus. 11 and 12 are the lower space and the upper space of the electrolytic cell 10 respectively and are designed with a certain volume, so that smooth flowing of the water in the electrode gaps is facilitated. Since in the water electrolysis process, the water molecules in the gaps can produce hydrogen and oxygen after being electrolyzed; the hydrogen and the oxygen can flow upwards along the gaps so as to drive the water in the gaps 3 to flow upwards from an upper port of each gap 3 into the space 12, leading the water to continuously flow into the electrode gaps for supplementation from the external of a lower port of each gap 3, i.e. a space 11. Apparently, if 11 and 12 are too narrow, the liquidity of the water in the electrode gaps may be influenced. The water which enters from the water inlet 15 of the electrolytic cell flows into 11 and cannot be electrolyzed through the gaps according to an expected flow rate, so that the water electrolysis efficiency can be lowered. In conclusion, the small spacing and large area of the gap 3 are reasonably selected, a certain liquidity of the water in the gap 3 is met, and technical solutions that coordinate and simultaneously consider the three aspects can obviously increased the electrolysis efficiency. Since the apparatus is used for electrolyzing the running water, generally speaking, if the spaces 11 and 12 outside the ports of the gap 3 are open enough, the liquidity of the water in the gap may be easily met so as to obtain higher electrolysis efficiency and water electrolysis indexes.

[0035] Note: electrolysis voltage of 8V, raw water: ORP=+408 mv, hydrogen content=0, normal temperature

[0036] It can be seen that water electrolysis index levels achieve the requirements for practical products.

[0037] Table 2 is actual detection data when the areas (i.e., the height of the electrodes) of the electrolysis electrode gaps 3 in FIG. 1A and FIG. 1B are increased by one time.

[0039] Note: electrolysis voltage of 8 V, raw water: ORP=+402 mv, hydrogen content=0, normal temperature

[0040] It can he seen that the area (i.e., the height of the electrodes) of the electrolysis electrode gaps 3 is increased by one time; the water electrolysis indexes are remarkably improved and exceed an index of an isolating membrane water electrolysis machine, while the electrolysis efficiency exceeds that of the isolating membrane water electrolysis machine by tens times and even a hundred times. It strongly verifies accuracy and great practical significance of the new principle and the new method of water electrolysis proposed by the applicant.

[0041] The electrolysis electrode assembly of the multifunctional membraneless boiled water electrolysis machine of the present invention is not limited to specific structure adopted by the embodiment 1. Any electrolysis electrode structure which can electrolyze boiled water and reach the required water electrolysis indexes in principle can be used. On an aspect of control, electrolysis of boiled water, warm water and normal-temperature water is easily realized to prepare the electrolyzed water with various temperatures. The present invention can conveniently obtain a larger quantity of high-performance electrolyzed water with various temperatures. The electrolyzed water not only has the efficacy of preventing and helping treating various diseases on a drinking aspect, but also can be used as washing water for washing pesticide and fertilizer pollution on the surfaces of fruits and vegetables, washing faces, beautifying the faces, bathing, cleaning skin and the like.
