Problems solved by technology

[0005] However, in such a conventional structure, in the rinsing process after washing, due to the difference in the method of the rinsing process selected by the user, there is the following problem: sometimes the softener put into the rinsing process is slightly different from the softening agent in the rinsing process. The detergent components remaining on the laundry will remove antibacterial agents such as silver ions, thereby hindering the antibacterial and sterilizing effects of antibacterial agents

Embodiment approach 1

[0021] figure 1 It is a longitudinal sectional view of the front-loading washing machine according to Embodiment 1 of the present invention, FIG. 2 is a control circuit diagram of a part of the front-loading washing machine in a block diagram, and FIG. 3 is an enlarged main view of an input setting unit and a display unit of the front-loading washing machine. view.

[0022] Such as figure 1 As shown, the rotary drum 24 is formed in a bottomed cylindrical shape, has a first opening 24a in its front, and is provided with a plurality of water holes 25 on the entire surface of the outer periphery of the rotary drum 24, and the rotary drum 24 is rotatable. It is arranged in the water tank 26. The rotation shaft (rotation center axis) 27 is provided in a slightly oblique direction along the rotation center of the rotary drum 24, and the axis direction of the rotary drum 24 is arranged to be inclined downward from the front side toward the back side. A motor 28 mounted on the ba...

[0045] Figure 5A and FIG. 5B are the first half and the second half of the flow chart of the main part of the drum-type washing machine according to Embodiment 2 of the present invention. The longitudinal sectional view, control circuit block diagram, input setting part and display part of the front-loading-type washing machine in the second embodiment are the same as those in the first embodiment. figure 1 , Figure 2 and Figure 3 for illustration.

[0046] The controller 44 of the second embodiment has at least one rinsing step after the at least two consecutive rinsing steps, and injects softener into the rotary drum 24 in the rinsing step before the last rinsing step. Other configurations are the same as those in Embodiment 1.

[0047] In this structure, use Figure 5A Operations of main parts of the front-loading washing machine according to Embodiment 2 will be described with reference to FIG. 5B . In addition, the description of the same part as the operation of Em...

Abstract

The present invention provides a drum-type washing machine. The drum-type washing machine according to the invention has a first rinsing procedure and a second rinsing procedure. After adding a softening agent into a rotating drum (step 110) in the first rinsing procedure, the following operations are executed in the first rinsing procedure and the second rinsing procedure: adding optical exciting antimicrobial water generated by an optical exciting antimicrobial agent generating part into a rotating drum (step 111 and step 120); and irradiating light into the rotating drum with a light radiating part (50) thereby enabling the softening agent to absorb the optical exciting antimicrobial agent and act on the clothes. The adhesion amount of optical exciting antimicrobial agent on the clothes can be increased, and a wider bactericidal and antimicrobial effect can be represented to bacterium and fungus.

Description

technical field [0001] The present invention relates to a drum type washing machine having a function of sterilizing laundry in a rotating drum having a rotation center axis in a horizontal direction or an inclined direction. Background technique [0002] In the past, in this type of drum type washing machine, silver ion water was brought into contact with the laundry during the dehydration operation, so that the silver ions were effectively attached to the laundry (for example, as a prior art document, refer to Japanese Patent Application Laid-Open No. 2004-57423 Bulletin). Or, the laundry is treated with silver ions at a concentration most suitable for the amount of laundry, such as more than 50ppb and less than 100ppb, or more than 50ppb and less than 900ppb, so that the antibacterial effect of silver ions can be fully brought into play (for example, as a prior art document , with reference to Japanese Patent Application Laid-Open No. 2004-105692). Alternatively, silver...
