Problems solved by technology

[0005] However, the above-mentioned existing non-diaphragm type electrolysis device cannot obtain alkaline reduced water with a wide range of alkalinity (from weakly alkaline to strongly alkaline, that is, the pH value is from 7-13)
1) The above-mentioned two kinds of electrolysis devices that apply high-frequency AC voltage or asymmetric AC voltage to the electrodes are to solve the problem of meeting drinking water standards, and at most can only generate neutral or weakly alkaline reduced water for drinking; 2 ) The above-mentioned electrolysis device that applies variable frequency DC pulse power to the electrodes, the first is that the time for preparing electrolyzed water is too long; the second is that only weakly alkaline reduced water can be obtained

Abstract

The invention relates to an alkali reductive water diaphragm-free electrolysis device, which belongs to the technical field of functional water electrolysis devices. The device comprises a water container, a pair of negative and positive electrodes placed in the water container, and a direct-current power supply electrically connected with the negative and positive electrodes; the positive electrode mainly comprises an active carbon electrode made of active carbon; and the negative electrode mainly comprises a metal electrode made of metal. The device can effectively obtain alkali reductive water of wide-range alkalinity (PH value from 7 to 13) and negative oxidation-reduction potential by adopting the negative and positive electrode group mainly comprising the active carbon electrode and the metal electrode, and can reduce the consumption of electrolysis power.

Description

technical field [0001] The invention relates to an electrolysis device for generating alkaline reduced water, belonging to the technical field of electrolysis functional water devices. Background technique [0002] Functional water is an aqueous solution with reproducible and beneficial functions obtained through scientific processing, and the scientific basis for its processing methods and physiological functions has been clearly confirmed. Strictly conforming to the above definition, and generally recognized by water research scientists, and has standards to implement is electrolyzed water (also known as "ionized water"). Electrolyzed water mainly includes oxidized water and reduced water. Generally, when the oxidation-reduction potential value (ORP value) of water measured using a silver-silver chloride electrode is +200mV as the median value, water with an oxidation-reduction potential value lower than the median value is called reduced water. Oxidized water is usually...
