no. 1 approach

[0038] refer to Figure 1 to Figure 15 , and the first embodiment will be described. First, refer to figure 1 , the overall structure of washing machine 1 according to the present embodiment will be described. The washing machine 1 is provided with a top cover 3 made of plastic on an upper portion of an outer case 2 formed of, for example, a steel plate to form a rectangular box shape as a whole. A water tank 4 capable of storing washing water is disposed inside the outer box 2, and the water tank 4 is elastically suspended and supported by an elastic suspension mechanism (not shown) of a known structure. In addition, although not shown, a drain port is formed at the bottom of the water tank 4, and a drain path including a drain valve is connected to the drain port.

[0039] In the water tank 4, a vertical axis type washing tank (rotary tank) 5 also serving as a dehydration tank is rotatably installed. Such as figure 2 As shown, the washing tank 5 has a bottomed cylindri...

no. 2 approach

[0099] Figure 16 It is a figure which shows 2nd Embodiment. This second embodiment differs from the first embodiment described above in the arrangement of the rollers 41 . That is, in this second embodiment, the same as the first embodiment, the roller 41 configured so that the outer diameter changes (gradually decreases) from the upper end to the lower end is used. And the two rollers 41 are provided in the upper part in the washing tub 5. As shown in FIG. Here, the upper part means that the roller 41 is located above the middle line M of the washing tub 5 .

[0100] According to the second embodiment, the roller 41 is provided in the washing tub 5 so that the clothes can be rotated well, and the outer diameter of the upper part of the roller 41 is larger than that of the lower part. Thereby, downward force can be applied to the laundry, and the washing effect can be further improved. At this time, since the roller 41 is provided near the upper part in the washing tub 5 ...

no. 3 approach

[0102] Figure 17 It is a figure which shows 3rd Embodiment. This third embodiment differs from the first embodiment described above in the structure of the rollers 71 . Contrary to the above-mentioned roller 41, the outer diameter of the roller 71 changes such that it is smallest at the upper end and becomes larger as it goes downward, that is, it is configured to have a tapered surface whose outer diameter is larger at the lower portion than at the upper portion. The rollers 71 are arranged at two positions in the circumferential direction of the inner wall of the washing tub 5 in the middle section in the vertical direction of the washing tub 5 .

[0103]According to the third embodiment, the laundry in contact with the roller 71 can be satisfactorily rotated in the circumferential direction. In addition, since the outer diameter of the lower part of the roller 71 is larger than that of the upper part, an upward force can be applied to the laundry. As a result, the clean...

Abstract

A washing machine of the embodiment of the invention is provided with a washing tank and a roller. The washing tank accommodates washing objects and washes the washing objects. The roller is rotatablyand freely arranged on the inner side wall part of the washing tank in the up-down direction state of an axial direction. The roller is used for promoting the washing objects to move through rotation. The roller is cylindrical and configured that the external diameter size varies in the up-down position.

Description

[0001] This application is based on and claims priority from Japanese Patent Application No. 2016-241193 filed on December 13, 2016, and the entire contents of this application are incorporated herein by reference. technical field [0002] Embodiments of the present invention relate to washing machines. Background technique [0003] In a so-called vertical axis type washing machine, it is conceivable to rotatably provide a roller on an upper surface portion of a pulsator provided at the bottom of the washing tub. In this case, two or three rollers are provided so as to extend in the radial direction on the pulsator, and the laundry can be rotated favorably on the pulsator by these rollers. [0004] In the above-mentioned washing machine with rollers on the pulsator, the moving effect of the laundry produced by the rollers only covers a part of the area on the pulsator, and the amount of laundry in the washing tank is large. , it is difficult to obtain the effect of improvin...
