Description

Washing machine The invention is a divisional application of the following application, and the original application information is as follows: International application number PCT/JP2018/000832 Application number 201880004925.X Application day, 2018, 01, 15 days Cleaning method, washing machine, tableware cleaner and toilet Technical Field Embodiments of the present invention relate to a cleaning method, a washing machine, a dish washer, and a toilet. Background In recent years, fine bubbles having a particle diameter of several tens nm to several μm, which are called microbubbles and nanobubbles, have been attracting attention, and a technique for cleaning a cleaning object using fine bubble water containing a plurality of fine bubbles has been proposed. Here, for example, in the case of cleaning greasy dirt, a surfactant such as a detergent is generally used. However, in the conventional constitution, the interaction between the fine bubbles and the surfactant is not sufficiently verified, and the effect of the interaction between the fine bubbles and the surfactant is not sufficiently extracted. Prior art literature: Patent literature: patent document 1 Japanese patent laid-open No. 2006-43103 Disclosure of Invention Problems to be solved by the invention Accordingly, a cleaning method, a washing machine, a dish washer, and a toilet stool using the cleaning method, which can improve cleaning efficiency by extracting an effect of interaction between fine bubbles and a surfactant, are provided. Means for solving the problems The cleaning method of the present embodiment is a cleaning method for cleaning a cleaning object by using a cleaning liquid in which fine bubble water containing 1×10 5 or more fine bubbles having a particle diameter of 500nm or less per 1ml and a surfactant are mixed. The washing machine, the dishwasher, and the toilet according to the present embodiment use a cleaning method in which a cleaning object is cleaned by a cleaning liquid in which fine bubble water containing 1×10 5 or more fine bubbles having a particle diameter of 500nm or less per 1ml and a surfactant are mixed.
