The present invention relates to an internal pressure closed type washing method and apparatus using physicochemical feature of nanobubble having an MNB pressing dissolving and concentration strengthening function, for enhancing cleanliness and reducing washing time by including a nanobubble circulation system in a washing machine so that washing water and rinsing water have physicochemical feature of dissolved oxygen and oxygen nanobubble. The washing method and apparatus convert to stronger nanobubble oxygen activated water by increasing solubility of air and dissolving and concentrating the dissolved oxygen and the oxygen nanobubble with higher concentration to the washing water and the rinsing water through adding of an MNB pressing dissolving and concentration method for treating with continuous circulation and a nanobubble method under the condition of room temperature or less and specific pressure with internal pressure closing of a washing tub. As a result, physicochemical feature of the dissolved oxygen and the nanobubble is maximized, thereby performing exceedingly enhancement of cleanliness and reduction of the washing time compared to the conventional nanobubble washing method. Accordingly, low detergent or non-detergent washing may be achieved. |
