2. Description of the Related Art Conventionally, stains on textiles such as clothes,
In particular, for stubborn mud stains, stains or oil stains such as collars and sleeves, a cleaning solution using a liquid or powder detergent (including super-con / bleach type) is applied directly to the soiled portion of the object to be cleaned. A cleaning method of brushing the contaminated part with a brush, a hand-washing method of rubbing an object to be cleaned in a cleaning solution, or a cleaning method of using a washing machine after immersing the object in the cleaning solution and the like is performed. However, there were complaints such as troublesomeness, rough hands, damaged fibers, and insufficient cleaning effect.

In the technique described in the above publication, a cloth or paper impregnated with water or a detergent or the like is applied to an object to be cleaned, and the ultrasonic generation head of an ultrasonic stain removing device is applied to the area. The cleaning is performed by contacting and transferring dirt on the object to be cleaned to cloth or paper. According to the technique described in the above publication, a vibrator is attached to the bottom of a washing tub of an ultrasonic washing machine, and bubbles are generated and eliminated in the washing machine using cavitation generated by a high-frequency vibrator. Cleaning is performed. In the technology described in the publication, an ultrasonic generator is disposed in a metal washing tub, a bubble generator is provided at the bottom of the washing tub, and air is supplied into the washing tub by the bubble generator. Cleaning is performed by switching the frequency of ultrasonic waves depending on the material and weaving method of the cloth used for clothing, that is, the type of the material. Also,

In the sixth embodiment, a giant magnetostrictive element is selected for at least one of the vibrators, and the period of the vibration generated by at least one of the vibrators is set to 10 kHz or less. A giant magnetostrictive element was selected, and in Example 6, a giant magnetostrictive element was employed as the upper vibrator, and a magnetostrictive element was employed as the lower vibrator. The equivalent was used.

(Comparative Example) The same as the above-mentioned Example, except that the cleaning liquid did not contain a surfactant and an enzyme. Comparative Example 1 and Comparative Example 2 in which only the lower side of the object to be cleaned was irradiated with ultrasonic waves at a frequency of 41 kHz. The same evaluation test as that of the example was performed for Comparative Example 3 in which ultrasonic waves were irradiated at a frequency of 41 kHz only from above the object to be cleaned and Comparative Example 4 in which the object was washed with a washing machine for 10 minutes.

The evaluation test was performed as follows. 15 g of red clay and 500 ml of water are uniformly stirred, and 10 cm × 1

(1) Washing with a washing solution containing at least a surfactant in a range of 5% by weight to 60% by weight or an enzyme in a range of 0.01% by weight to 10% by weight is disposed in an opposed state. The object to be cleaned is positioned between the irradiation surfaces of the vibration means (ultrasonic irradiation means) and has a frequency of 0.1 kHz to 100 kHz.
The cleaning effect can be improved by the synergistic effect with the vibration or ultrasonic cleaning in the range described above. (2) Vibration or ultrasonic waves are applied to the cleaning liquid and the object to be cleaned from a short distance of 1 cm or less from the irradiation surface of the vibration means (ultrasonic irradiation means), and the object to be cleaned is vibrated from both sides. Since the concentration is achieved by irradiating the ultrasonic waves, the cleaning power of the cleaning liquid containing the surfactant and the enzyme can be improved. (3) Since washing is performed without applying vibration or irradiating ultrasonic waves and stirring, the effect on the fibers during washing can be reduced. (4) Since cleaning can be performed without damaging the fibers, cleaning can be performed corresponding to high-grade fibers such as ties. (5) The vibrating means (ultrasonic wave irradiating means) can be detached from the cleaning container, or a removable and movable inner container is arranged inside the cleaning container, and the vibrating means (ultrasonic wave irradiating means) is provided on the inner container.
