Problems solved by technology

[0008] However, in such an existing drum type washing machine, since the amount of water that can be circulated by the circulation pump is different due to the power of the circulation pump, if you want to add enough washing water to the laundry, you need a very large circulation pump.
However, when trying to miniaturize the body of the washing machine, the circulation pump has to be reduced, but this will cause the problem that a sufficient circulation flow cannot be obtained.
Moreover, the circulating pump will become a new component, which will complicate the body structure and increase the manufacturing cost

Embodiment 1

[0027] figure 1 A cross-sectional view of the front-loading washing machine in the first embodiment of the present invention is shown in . Such as figure 1 As shown in , the body 1 of the front-loading washing machine is provided with a cylindrical outer tub 6 with a bottom. This outer tub 6 is supported by a shock absorbing structure not shown in the figure, and is supported as a The state of being inclined downward in the direction from the front side to the back side. The outer barrel 6 is composed of the outer barrel body 2 and the outer barrel cover 3, and the first sealing member 4 is placed between the connecting parts for connecting and fixing. Inside the outer tub 6 is provided a rotatable rotary drum 5 also in the shape of a bottomed cylinder, and the rotary shaft of the rotary drum 5 is supported so as to be inclined downward in the direction from the front side to the rear side of the body 1. .

[0028] The front side of the machine body 1 is provided with a ...

Embodiment 2

[0071] Figure 8 It is a perspective view of the outer barrel body 42 in the second embodiment of the present invention. Wherein, for the same components as those in Embodiment 1, only the same symbols are assigned here, and their detailed descriptions are omitted.

[0072] Such as Figure 8 As shown in , on the inner wall near the junction of the outer barrel bottom portion 42c and the outer barrel barrel portion 42b in the outer barrel barrel portion 42b, an outer barrel barrel groove 42e roughly forming a concave shape is provided. , the outer barrel barrel groove 42e is roughly in the shape of an arc concentric with the outer barrel barrel portion 42b. The outer barrel body groove 42e is fixed with the outer barrel body groove cover 43 corresponding to the shape of the outer barrel body groove 42e from the inner wall surface side, and its outer part is cushioned by the 4th sealing member 44 that is located near the outer periphery. Screw 45 is tightened, fixed. The out...

Embodiment 3

[0081] Figure 10 It is a plan view seen from the outside of the rotary drum bottom 5d of the rotary drum 5 in the third embodiment of the present invention.

[0082] Such as Figure 10 As shown in , the height of the rib 55 in the rib mounting part 54 is substantially the same as that of the outer wall 40 and the inner wall 41, and is along the flow direction of the washing water rotating in the outer tub 6 in the direction toward the outer circumference side. The specified angle is tilted. In addition, the same constituent elements as those in Embodiment 1 are assigned the same symbols, and their repeated descriptions are omitted.

[0083] The operation and effect of the drum type washing machine having the above constitution will be described below.

[0084] During the washing stroke, the rotating drum 5 Figure 10 The direction indicated by the arrow D in the rotation occurs at a specified rotation speed (such as 80 rpm). Same as in Embodiment 1, the washing water is ...

Abstract

To provide a drum type washing machine capable of improving detergency while suppressing the manufacturing cost low and reducing the uneven washing by returning wash water in an outer tub into a rotating drum without using a circulation pump or the like. This drum type washing machine is provided with: a casing (1); the bottomed cylindrical outer tub (6) incorporated in the casing (1) and having a first opening part (3a) for loading / unloading clothes; and the bottomed cylindrical rotating drum (5) rotatably incorporated in the outer tub (6), having a second opening part (5a) opened corresponding to the first opening part (3a), and having the rotation axis in the horizontal direction or in the direction inclined from the horizontal direction. The outer tub (6) is provided with a water intake port (20) allowing the entering of the wash water rotating inside the outer tub (6) with the rotation of the rotating drum (5), circulation channels (22, 26, 27, 28) having one ends communicated with the water intake port (20), and an outlet (32) communicated with the other ends of the circulation channels (22, 26, 27, 28) and discharging the wash water into the rotating drum (5).

Description

technical field [0001] The invention relates to a drum type washing machine which performs various processes such as washing, rinsing and dehydration in a rotating drum whose rotating shaft is arranged in a horizontal direction or an inclined direction. Background technique [0002] Firstly, the existing drum type washing machine of this type will be described. [0003] Figure 13 It is a cross-sectional view of a drum type washing machine in which the rotating shaft of the rotating drum is in the horizontal direction. Inside the body 101 of the drum type washing machine, there are provided an outer tub 102 supported by a buffer member, and a rotary drum 103 rotatably supported in the outer tub 102 . The rotating drum 103 rotates under the driving of the driving motor 104 . The front side of the machine body 101 is provided with a door 105 that can be opened and closed freely. After the door 105 is opened, it can be put into the rotating drum 103 through the opening 102a o...
