Problems solved by technology

[0004] For example, in a so-called vertical axis type washing machine in which a washing tub double-used as a dehydration tub is provided with a washing tub that is rotatable around a vertical axis in the tub, there are such things as the outer peripheral surface of the washing tub or the inner surface of the tub that are difficult for the user. Problems with dirt or detergent residue attached to places seen
If such dirt is left, there will be black mold, etc., and there will be problems such as odor generation and reattachment to the laundry.

no. 1 approach

[0021] refer to Figure 1 to Figure 4 The first embodiment will be described. figure 1 The internal structure of the washing machine 1 according to this embodiment is schematically shown, and first, the overall structure of the washing machine 1 will be described. Here, the washing machine 1 is provided with a top cover 3 made of synthetic resin, for example, on an upper portion of an outer case 2 formed in a rectangular box shape from steel plates as a whole.

[0022] Inside the outer case 2, a tub 4 capable of storing washing water is provided elastically suspended and supported by an elastic suspension mechanism 5 having a known configuration. A drain port 6 is formed at the bottom of the tub 4 . A drain path 8 including an electronically controlled drain valve 7 is connected to the drain port 6 . The drain mechanism is constituted by the drain valve 7 and the like. In addition, although not shown in detail, an air chamber is provided at the bottom of the tub 4, and a w...

no. 2 approach

[0066] Figure 5 Shows the second embodiment. This second embodiment differs from the first embodiment described above in the control performed by the control device 21 from the rinsing process to the final spin-drying process. That is, in this embodiment, the control device 21 uses the second water supply path 28 to supply tap water to perform the process of storing and rinsing, and after the rinsing process, the drain valve 7 is opened to discharge all the water in the washing tub 10, that is, the tub 4. . Then, the control device 21 opens the first water supply valve 29, and uses the first water supply path 27 to supply microbubble water into the washing tub 10 to a predetermined water level, for example, 25 liters in volume, to perform residual water dehydration.

[0067] Specifically, as Figure 5 As shown, if the water storage rinse starts (time T0), then in the state where the drain valve 7 is closed, the second water supply valve 30 is opened, and the second water s...

no. 3 approach

[0072] Figure 6 shows the third embodiment. Should Figure 6 Still shown is the control state carried out by the control device 21 from the rinsing process to the final spinning process. The difference between the third embodiment and the above-mentioned second embodiment is as follows, that is, after the rinsing process, the control device 21 opens the drain valve 7 to discharge all the water in the washing tub 10, that is, the tub 4, and then drains the water in the washing tub. In 10, water in a state in which microbubble water and tap water are mixed is supplied to a predetermined water level, for example, a capacity of 25 liters, and the residual water dehydration operation is performed.

[0073] Specifically, as Figure 6As shown, the process of storing and rinsing is performed in the same manner as in the second embodiment, and when the operation of storing and rinsing is completed (time T12 ), the remaining water dehydration operation is started. In this residual ...

Abstract

The washing machine (1) according an embodiment of the present invention includes: a water tank (4); a washing tub (10) which is provided inside the water tank (4) and accommodates clothes; an agitator (12) which is provided at the bottom of the washing tub (10); a water supply mechanism (25) which supplies water to the washing tub (10); a fine bubble generator (31) which generates fine bubble water in which fine bubbles are mixed; a drainage mechanism (7) which drains water from the washing tub (10); a drive mechanism (15) which rotates and drives the agitator (12) and the washing tub (10); and a control device (21) which controls each mechanism (25, 31, 7, 15) and performs washing, rinsing, and spin-drying. Before moving onto spin-drying after rinsing, the control device (21) performs aremaining-water dehydrating operation of rotating the washing tub (10) up to a predetermined rotation speed in a state in which water including the fine bubble water generated by the fine bubble generator (31) is left in the washing tub (10) at a predetermined water level.

Description

[0001] Cross-references to related applications [0002] This application is based on Japanese Application No. 2017-042735 filed on March 7, 2017, and the content of the description is cited here. technical field [0003] Embodiments of the present invention relate to a washing machine. Background technique [0004] For example, in a so-called vertical axis type washing machine in which a washing tub double-used as a dehydration tub is provided with a washing tub that is rotatable around a vertical axis in the tub, there are such things as the outer peripheral surface of the washing tub or the inner surface of the tub that are difficult for the user. See the problem of dirt or detergent residue attached to the place. If such dirt is left, problems such as black mold and the like are generated, odor generation, and reattachment to laundry appear. Conventionally, in a so-called horizontal axis type front-loading washing machine, it has been considered to perform a rotating d...
