Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drum-type washing machine that performs so-called tumble washing by placing clothes in a rotating drum.The present invention facilitates the shaping of the rotating drum, and also improves the washing effect by loosening the clothes as much as possible and washing them. The aim is to improve the

The rotating drum of this type of washing machine has a plurality of long baffles integrally formed on the inner surface of the washing machine so as to protrude along the washing machine side wall, and is rotated by horizontally supporting the baffles at both ends.

A slide core has been used when the rotating drum and baffle are integrally molded from resin. The use of a cutting slide core complicates the molding operation and has the disadvantage of prolonging the molding cycle.

Therefore, as a molding method that does not use a slide core, it has been considered to provide a mold cutting slope on the side wall of the rotary drum and to also make the tip of the baffle slope to one side in accordance with the slope. However, with this method, the clothes move to one side along the gradient or inclination and accumulate during rotation, which reduces the washing effect and causes new drawbacks such as increased vibration. The present invention aims to eliminate the above-mentioned drawbacks, and the opening angle of the baffle having an inclined tip is gradually decreased toward the lower side. As a result, the clothes that have been hung up by the baffle are allowed to fall from the high side where the opening angle of the baffle is large, and as they fall, the clothes are pulled to the high side, preventing them from accumulating on the low side, and loosening the clothes. It can be done. In addition, even if the clothes are piled up, when the clothes are hung on the baffle and lifted up, they will collapse to the higher side and fall from the collapsed side, making it easier to remove the clothes.
It can be loosened. Hereinafter, the present invention will be described based on drawings showing embodiments. Reference numeral 1 denotes a horizontally supported rotary drum, in which an opening 2 of a resin-molded bottomed cylindrical body is closed by an end plate 3. be.

Reference numeral 4 designates a short cylindrical shaft protruding from the outer surface of each of the bottom surface 5 and the end plate 3, and reference numeral 6 designates a through hole opened in the side wall 7.

The station side wall 7 has a mold-cutting slope that widens toward the opening side. 8... is a chevron-shaped baffle formed integrally and long in the axial direction on the inner surface of the circumferential wall 7,
It is formed into a stepped shape divided into four parts in the axial direction, with the protruding end becoming lower in order toward the opening side, and furthermore, the opening angle 0 of the peak becomes smaller in order towards the opening side.

That is, the angle θ1 in the figure is θ2. Next, to explain the operation of the present invention, first open the hatch 9 inside the rotating drum 1 and put the clothes w in it, then supply water to a predetermined water level in the outer tank housing the rotating drum 1, and add an appropriate amount of detergent. Then, rotate the rotating drum 1.

As a result of this rotation, the clothes W are caught on the baffles 8, lifted up, dropped, and washed, but normally they tend to shift toward the opening due to the slope of the circumferential wall 7 and end up on the opening side. Trying to accumulate (see Figure 3 A, mouth). However, since the opening angle θ on the bottom side of baffle 8 is large, the clothes W that have been hooked and lifted fall quickly from the bottom side, and are dragged by the clothes W on the bottom side to the opening side. Clothing W
It drops. That is, the clothes W that are about to pass toward the opening are pulled down to the bottom side, and are prevented from accumulating on the opening side (see FIG. 3, c). In addition, when clothes W accumulate on the opening side, when the accumulated clothes W are hooked up by the baffle 8 and raised, they also collapse to the bottom side 1 on the way, and as mentioned above, the clothes on the bottom side Since the clothes W on the opening side are pulled down from the clothes W, the clothes W can be loosened by preventing the clothes W from being piled up again. In this way, when the clothes W are dropped, they loosen and fall, so the washing effect is improved.

When the clothes W shift from the bottom side to the opening side, or from the opening side to the bottom side, they are rubbed by the steps of the baffle 8, and are scrubbed here, further improving the washing effect. . Further, rinsing is also performed within this rotating drum 1, and hot air can also be sent for drying. In the embodiment of the present invention, the baffles 8... are formed in a step-like manner and scrubbing is added to improve the washing effect. The through holes 6 can be formed at the same time as molding, and in this case there is an advantage that drilling work using a drill or the like can be omitted.

However, if the task of loosening clothes W is to be performed by preventing the accumulation of clothes W, the baffles 8 do not necessarily need to be formed in a step-like manner, but may be formed as long as the opening angle e changes steplessly. It is something. As described above, in the drum-type washing machine according to the present invention, since the rotary drum and the baffle are provided with a mold-cutting slope and an inclination, molding becomes very easy.

In addition, since the opening angle of the slanted baffle is gradually reduced toward the lower side, it is possible to prevent the accumulation of clothes and loosen them, thereby improving the effectiveness of washing, rinsing, or drying, and as a result, reducing the time required for washing, rinsing, or drying. .
