  Hereinafter, a drum type washing machine according to an embodiment of the present invention will be described with reference to FIGS. 1 to 7 for understanding of the present invention. In addition, the following description is a specific example of this invention, Comprising: The content of description of a claim is not limited.

  As shown in FIG. 1, the drum-type washing machine 1 of the present embodiment shown in FIGS. 1 and 2 has a rotating drum 2 formed in a bottomed cylindrical shape from the opening front side to the back side as the bottom. The rotating shaft 20 is inclined in the downward direction from the horizontal direction so that the rotating shaft 20 is installed in the water tank 3 that is floatingly supported by the suspension, and the opening / closing lid 5 provided at the front part of the washing machine casing 4 is opened to open the laundry. Is stored in the rotating drum 2 and the rotating drum 2 is driven by the motor 6 so that at least one of a washing process, a rinsing process, and a dehydrating process can be performed. As shown in FIGS. 1 to 3, the opening / closing lid 5 is applied to a lid body 8 having a window 7 fitted with a transparent glass plate 11 through which the laundry is seen from the outside, and the front surface of the lid body 8. The lid cover 9 is made transparent so that the necessary fluoroscopic area leaving the front area or the periphery is left. The lid body 8 has a lid frame 8a molded from polypropylene, a back frame 8b molded from polypropylene having higher chemical resistance, and a glass plate 11 sandwiched between its peripheral portions, and a screw 66 as shown in FIG. It is fixed. The lid cover 9 is formed of transparent ABS.

  By the way, in the drum type washing machine 1 of the present embodiment, the closed opening / closing lid 5 is inclined to the rear side at an angle different from the opening end 2a of the rotating drum 2 as shown in FIG. Since the opening / closing lid 5 has an inclination, it is possible to see from the outside in the rotary drum 2 having a sufficient inclination suitable for taking in / out laundry, washing, rinsing, and dewatering, and an opening / closing port 12 provided in the opening / closing lid 5. It is ensured that there is no particular inconvenience in and out of the laundry with respect to the rotating drum 2 through. For this purpose, the annular window packing 13 that seals between the open end 3a of the water tank 3 and the closed opening / closing lid 5 is tapered in a side view and has a sectional shape like the annular window packing described in Patent Document 1. If the volume of each cross-section becomes uneven in the circumferential direction, the load when receiving an external vibration force that becomes particularly large at the opening end 3a of the water tank 3 is amplified and concentrated in a local area with a large volume, resulting in early damage. Causes premature breakage.

  To cope with this, the opening / closing lid 5 and the opening end 3a of the water tank 3 can be sealed with an annular window packing 13 having a substantially uniform cross section and volume in the circumferential direction and having excellent durability. With the lid 5 in the closed state, as shown in FIG. 1, the opening end 3 a of the water tank 3 is in contact with the rotating drum 2 in a relationship inclined at a different angle from the opening end 2 a perpendicular to the rotating shaft 20 of the rotating drum 2. The front and rear ends 13a, 13b are substantially parallel to each other between the opening / closing lid 5 and the opening end 3a of the water tank 3 so as to face the opening / closing lid 5 which projects to the front side of the opening end 2a and is closed. Sealing is performed with an annular window packing 13. Thus, the opening / closing lid 5 is closed after the laundry is accommodated in the rotating drum 2, and the rotating drum 2 is rotated to perform at least one of a washing process, a rinsing process, and a dehydrating process. It is possible to prevent leakage of water, dewatering splashes, and the like between the annular window packing 13 that seals between the opening end 3 a of the water tank 3. Further, while the opening / closing lid 5 and the opening end 2a of the rotating drum 2 have the above-described characteristics depending on the inclination angle, the opening end 3a of the water tank 3 has an inclination parallel to the opening / closing lid 5 and is between them. Are sealed by the annular window packing 13 with the front and rear ends 13a and 13b parallel to each other. Therefore, the window packing 13 may have a uniform cross-sectional shape and a volume of each cross-sectional portion in the circumferential direction.

  As a result, the gap between the opening / closing lid 5 that is inclined at a different angle from the opening end 2a of the rotating drum 2 and the opening end 3a of the water tank 3 housing the rotating drum 2 is sealed, so that washing water, rinsing water, dehydration The annular window packing 13 that prevents the splashes of the water from leaking outside makes the opening / closing lid 5 and the opening end 3a of the water tank 3 substantially parallel to each other so that the front and rear ends 13a and 13b are substantially parallel to each other. The window packing 13 has the same cross-sectional shape and volume in each cross-section in the circumferential direction, so that the opening end 3a of the swinging water tank 3 and the open / close lid 5 that is stopped The load when repeatedly receiving compression and deformation forces with circumferential displacement is equalized in the circumferential direction and does not concentrate and concentrate locally, resulting in long life without damage or breakage at an early stage. .

  On the other hand, the opening / closing lid 5 is inclined to the rear side from the body panel 41 forming the front surface 4a of the washing machine casing 4, and is inclined to the rear side of the recessed portion 42 which is an annular region recessed from the front surface 4a. It is in the relationship which closes the entrance / exit 12 opened to a bottom part. As described above, since the opening / closing lid 5 and the entrance / exit 12 are tilted backward with respect to the front surface 4a of the washing machine casing 4, the inclination of the rotary drum 2 is independent of the angle of the front surface 4a of the washing machine casing 4. Together with the posture, it is convenient for taking in and out the laundry and seeing the laundry from the outside. The angle of the front surface 4a of the washing machine casing 4 is vertical to the horizontal direction, the opening / closing lid with respect to the horizontal, and the rear tilt angle of the entrance 12 You can choose freely including backward tilt. As a result, the opening / closing lid 5 and the entrance / exit 12 are tilted rearward with respect to the front surface 4a of the washing machine casing 4, and the tilted attitude of the rotary drum 2 regardless of the angle of the front surface 4a of the washing machine casing 4, It is convenient and easy to use for taking in and out the laundry and seeing the laundry from the outside, and the angle of the front surface 4a of the washing machine housing 4 is increased in the degree of freedom of selection including vertical and backward tilt. Easy to meet applications and requirements.
