Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drum type washing machine, and particularly to improving the washing effect by a baffle formed in a rotating drum.

Furthermore, the through holes are formed at the same time as the rotary drum is molded, thereby eliminating the need for a drilling operation. This type of washing machine usually has three baffles protruding from the inner surface of the rotating drum, but the degree of protrusion of these baffles is almost constant, and the ridgeline has only a scrubbing effect, and is used exclusively for pounding. I was getting used to it.

Therefore, it lacked the ability to clean properly.
In the present invention, the baffle is shaped like a step. This is intended to dramatically increase the scrubbing effect at the stepped portion and improve the washing effect. Further, the present invention aims to omit the drilling work by forming through holes on the protruding wall surface of the baffle at the same time as the baffle molding, so that the inside and outside of the rotating drum are communicated and the washing water flows through the holes. below,
The present invention will be described based on drawings showing embodiments. Reference numeral 1 denotes a rotary drum made of resin that is rotatably disposed in the outer tank of the aircraft body, and the opening of the horizontally oriented bottomed cylindrical body 2 constitutes the rear end surface. It is "closed" by an end plate 3.

Here, the diameter of the bottomed cylindrical body 2 is gradually reduced toward the bottom, and the bottom plate 4 constitutes a front end surface. Reference numerals 5 and 5 designate rotary shafts that are integrally provided on the outer surfaces of the end plate 3 and the bottom plate 4, and rotatably support the rotary drum 1 in the outer tank.

Note that 6... is an inlet for drying hot air provided in the end plate 3. 7... is a baffle formed integrally and long on the inner surface of the cylindrical body 2 from the opening side toward the bottom plate 4, and is formed in a step-like shape gradually increasing in height toward the bottom plate 4, It is integrally arranged in the vicinity of the protruding portion of the rotating shaft 5.

Reference numeral 8 is a through hole formed in the protruding wall surface of the baffle 7, which communicates the inside and outside of the drum to allow washing water and drying hot air to circulate.

In the embodiment, the through holes 8 are provided at the corner portions between the cylindrical body 2 and the stepped portions, but they may be provided at protruding portions. Next, the bottomed cylindrical body 2, the baffle 7...
. . . and the through hole 8 . . . are integrally molded with a mold that is cut out in the axial direction. made at the same time.

That is, there is no need to use a slide core or the like during this molding, and the molding cycle can also be shortened. Clothes are put into the rotating drum 1 through an opening previously opened on the circumferential side thereof, and after the opening is closed, the clothing is rotated within the drum.

That is, it is caught by the baffle 7, carried upwards, and falls. Also, at that time, baffle 7...
It is rubbed by the many steps of... Therefore, when washing, beating and scrubbing are used together, resulting in a great washing effect. Also, during drying, a fan (not shown) driven by a motor (not shown) that rotates the drum 1,
Hot air is introduced into the drum 1 from the inlet 6...
The clothes are dried and exit through hole 8. As described above, since the drum-type washing machine according to the present invention has the baffle formed in a step-like manner, the clothes can be rubbed well on the stepped portion, and by using both beating and scrubbing, this kind of drum-type washing machine The washing function of a type washing machine can be significantly improved. In addition, since the steps of the baffle are made higher in the direction of the small diameter of the bottomed cylindrical body, removing the mold during drum molding only requires movement in the axial direction, and since the steps are long in the axial direction, it is easier to separate the steps when removing the mold. The mold becomes easy. Furthermore, since the baffles are provided in a stepped manner, the through holes can be made simultaneously in the buckle protruding wall by butting the male and female parts, and there is no need to use a slide core or the like for this purpose, and the molding cycle can also be shortened. In addition, it is possible to omit the work of making holes using a drill or the like after molding.
