After the machine door 54 is opened, laundry can be put into/taken out of the rotary drum 51 through the laundry inlet and outlet 58 provided on the front of the tub 53 .

When doing laundry, the machine door 54 is opened, laundry is dropped into the rotary drum 51, and then washing powder is dropped, and then the operation is started. After the operation starts, add water in the water tank 53 earlier, and the added water also enters in the rotary drum 51 through the through hole 52, so that the specified water yield is also reached in the rotary drum 51. Then, the drum driving motor 55 drives the rotating drum 51 to rotate at a specified rotational speed, and the laundry contained in the rotating drum 51 will be hooked by the stirring protrusions 56 provided on the inner wall surface of the rotating drum 51, and will be drawn upward along the direction of rotation. Lift it up, reach the proper height and drop it again. In this way, the effect of knocking washing can be applied on the laundry, thereby washing it. After the washing step is completed, the dirty washing water is drained, and a rinsing operation is performed using newly added water. After the rinsing operation is completed, the rotary drum 51 is rotated at a high speed to perform a dehydration operation. These operation steps are carried out automatically according to the prescribed control sequence. For an example thereof, refer to pages 3-5 and FIG. 1 of Japanese Patent Application Laid-Open No. Hei 09-215893.

Detailed ways

Fig. 1 is a schematic structural diagram of a drum-type washing machine 1 in an embodiment of the present invention. In the figure, the water tub 3 is supported in the washing machine body 2 by a suspension mechanism not shown in the figure, and a cylindrical rotating drum 5 with a bottom is arranged in the water tub 3, and the rotation axis direction R of the rotating drum 5 is set to It is inclined at an angle θ from the horizontal direction H.

In the bottomed cylindrical rotary drum 5 , the opening side is provided on the front side of the washing machine body 2 , and the bottom side is located on the back side of the washing machine body 2 . The rotation axis R of the rotating drum 5 is set in the tub 3 to slope downward at an angle θ from the front side to the back side, and the drum driving motor 4 installed on the back of the tub 3 drives the rotating drum 5 to rotate. In the bucket 3, a bucket cover 3b combined with it is provided on the open end of the bottomed cylindrical bucket body 3a, and the bucket cover 3b is provided with a water tank cover 3b for turning in the rotating drum 5. A laundry inlet and outlet 11 for putting in/taking out laundry. Corresponding to the laundry inlet and outlet 11, an openable and closable door 8 is provided on an inclined surface 2a provided on the front side of the washing machine body 2. As shown in FIG. After the machine door 8 is opened, the laundry can be put into the rotary drum 5 or taken out therefrom. By making a part or the whole of the door 8 transparent, the operation inside the rotary drum 5 can be seen from the outside. In addition, a bellows 15 made of soft elastic material is provided around the laundry inlet and outlet 11; when the machine door 8 is closed, its inner surface presses against one end of the bellows 15, thereby preventing water from flowing from Splash outside the machine in the water bucket 3.

In the above structure, by setting the rotary drum 5 at an inclination, and the washing machine body 2 is provided with a machine door 8 facing the opening of the rotary drum 5 , when the door 8 is opened, input/take out of the rotary drum 5 is performed. During the operation of laundry, the degree of bending can be reduced, and there is no need to ensure a surplus space on the front side of the drum-type washing machine 1. In narrow spaces such as the washroom where the existing vertical washing machine is installed, the drum-type washing machine of the present utility model A washing machine 1 can also be provided. In this way, it is possible to constitute a drum-type washing machine 1 suitable for a narrow living environment.

The central position of the laundry inlet and outlet 11 is set to have a certain eccentricity upward from the rotation axis R of the rotary drum 5, and the central position of the machine door 8 facing the laundry inlet and outlet 11 is set to be aligned with the laundry. The centerlines of the entrances and exits 11 are roughly the same. The diameter of the machine door 8 has an optimal size due to factors such as being restricted by the setting place of the drum type washing machine 1, and is generally set to be smaller than the opening diameter of the rotary drum 5. In addition, since the diameter of the laundry inlet/outlet 11 is set according to the diameter of the machine door 8, it is also smaller than the opening diameter of the rotary drum 5. Therefore, when the central position of the laundry inlet and outlet 11 and the machine door 8 is set to a position eccentric upward from the rotation axis of the rotary drum 5, when the door 8 is opened and the inside of the rotary drum 5 is observed through the laundry inlet and outlet 11, there will be a dead angle. Part will reduce, and just can be contained in the laundry in the rotary drum 5 in a very large range, and the situation of forgetting to take out the laundry is just difficult to take place. Especially in the drum-type washing machine 1 in this embodiment, the rotating drum 5 is inclined, and the inclined surface 2a is provided with a machine door 8 corresponding to the inclination angle of the rotating drum 5, so it can be seen in a larger range. To the internal situation of the rotating drum 5.

After carrying out various investigations, the inventor of the present application concluded that the inclination angle θ of the rotary drum 5 installed obliquely is optimal at 30±5 degrees. By tilting the rotary drum 5 at such an angle of inclination (that is, θ=30±5 degrees), even children (except infants), adults, or disabled persons who use wheelchairs with different heights can complete the input very conveniently. /The operation of taking out the laundry. On the basis that the rotary drum 5 is arranged obliquely, by eccentrically eccentrically the center position of the laundry inlet and outlet 11 and the machine door 8 upward from the rotation axis R of the rotary drum 5, not only the input/take-out of the laundry becomes easier, but also From the transparent machine door 8, it is easier to observe the operating status of each operating step in the laundry process.

However, when the opening diameter of the laundry inlet and outlet 11 is smaller than that of the rotary drum 5, and the central position of the laundry outlet/port 11 is biased to one side from the rotational axis R of the rotary drum 5, the bottom of the bucket cover 3b will As shown in the figure, the opening part of the rotary drum 5 will be covered a little. In this state, if part of the laundry protrudes from the opening end of the rotary drum 5, the protruding part may be caught between the rotary drum 5 and the tub cover 3b as the rotary drum 5 rotates.

In order to prevent the laundry from being entangled, a crescent-shaped anti-winding protrusion 16 is provided on the part of the tub cover 3b that covers the opening end of the rotating drum 5, and the anti-winding protrusion 16 is set to protrude toward the inside of the rotating drum 5 (see figure 1).

FIG. 2 shows the state of the tub lid 3b seen from the inside. The laundry inlet and outlet 11 is provided at a position eccentric upward from the center (that is, the center of the rotary drum 5 ), and a crescent-shaped anti-tangle is provided at a position centered in a direction opposite to the eccentric direction of the laundry inlet and outlet 11 . Protrusions 16 , the anti-winding protrusions 16 are arranged to protrude toward the inside of the rotary drum 5 .

After such anti-winding protrusions 16 are provided, the laundry part protruding from the rotary drum 5 will not enter the space between the rotary drum 5 and the tub cover 3b, thereby preventing the laundry from being damaged due to the opening of the laundry inlet and outlet 11. The laundry is entangled due to the eccentric position.

When the rotary drum 5 is installed obliquely as described above, it is easy to put in/take out the laundry, and the water added to the rotary drum 5 will be accumulated on the back side, even if the amount of water is small. The advantages of deep water storage state. But, the laundry that is contained in the rotating drum 5 can accumulate in the lower part of the bottom surface side that is in the lowest position, and when the rotary drum 5 rotates, the laundry can be more likely to accumulate on the bottom surface side, and the laundry on each position cannot There is a problem that it is not possible to apply a uniform cleaning effect to all the laundry due to sufficient transposition. However, in the drum type washing machine 1 in this embodiment, the position of the laundry is fully exchanged by controlling the rotational drive of the rotary drum 5 by the drum drive motor 4, or by means of the inner peripheral wall of the rotary drum 5. The unique shape of the agitating protrusions 9 on the top makes the position of the washings fully exchanged.

To sum up, if the utility model is adopted, since the central position of the laundry inlet and outlet on the tub is set at a position eccentric from the rotational axis of the rotating drum, the opening corresponding to the laundry inlet and outlet can be opened. When the machine door is in the right position, the internal situation of the rotary drum can be seen in a large range, and the state of the laundry in the rotary drum can be fully confirmed, so that it can form a kind of laundry that is not easy to forget to put the laundry in the dead corner. Take out and use the convenient front-load washing machine.
