Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotating drum washing machine for professional use.

Conventionally, this type of washing machine consists of an inner drum and an outer drum, and the inner drum rotates for a certain amount of time, then rotates in the opposite direction, and this process is repeated to remove dirt.There are three or four bars on the inside of the inner drum. When the drum rotates, the laundry in it is pulled up by this crosspiece, falls down, is compressed, and is beaten to remove dirt, but it takes an extremely large amount of effort to take out the laundry to dehydrate it after washing. This has become a major issue within the industry.

That is, due to the structure of the drum, the laundry outlet is on the side, and since the laundry contains a large amount of washing liquid and is heavy, the task of taking out the laundry is hard work, covering the drum with washing liquid.

Additionally, a washing machine with a dehydrator has been put into practical use as an improved version of this, but this has a complicated structure that divides the room into four sections and requires balance, making it difficult to operate and causing problems such as forgetting to tighten the lid. However, there were drawbacks that could lead to more serious accidents.

The present invention was invented in view of the above, and an object of the present invention is to eliminate the above-mentioned drawbacks by providing a washing machine that can automatically load and discharge laundry into and out of a drum.

It opens at 8.

Note that a chain or the like may be used instead of the belt 9 for one drive of the drum 4.

The present invention is as described above, and the usage thereof will be explained below.

First, operate the motor jack 13 to move the piston rod 1.
Aspirate 5.

Then, the piston rod 15 pulls the front end of the movable frame 2, so that the movable frame 2 is tilted at approximately 30° about the pivot 3 as shown in FIG. 2B.

Next, cylinder 24 is activated. The arm 21 is pressed by the piston rod 26 and rotates around the support portion 27 as shown in FIG. 3 to open the lid 17.

Next, the laundry is automatically thrown into the drum 4.

At this time, it is preferable to move the bag containing the laundry to the upper part of the opening, open the lower part thereof and let it fall, or to throw it in with a chute.

Next, the cylinder 24 is operated to cover the lid 17, and the motor jack 13 is operated to place the drum 4 in a horizontal state.

Next, the electromagnetic valve 46 is activated to inject the washing liquid into the drum 4.

After that, the motor 7 is driven. Then, the drum 4 is rotated forward and backward together with the front and rear lids 17 and 29 by the belt 9, and washing is performed.

In this case, the drum 4 is guided in rotation by a plurality of guide rollers 5, and is also supported in the front and rear directions by support rollers 12.

Next, during drainage, the motor 7 is driven to operate the cylinder 32 while the drum 4 is still rotating.

Then, the piston rod 33 presses the connecting plate 34 and rotates the connecting plate 34 around the support part 36, so that the pipe 3
4 and the lid 29 slide rearward.

As a result, the rear of the drum 4 is opened, so that the washing water flows out from the through hole 18 of the punching metal 28 and drains into the drain 37.
Water is drained from the drain port 39 into the drain pit 49.

In this case, since the drain 37 covers the ends of the drum 4 and the lid 29, the washing water flowing out from the punching metal 28 does not scatter outward.

Next, after operating the cylinder 24 to open the lid 17, the motor jack 13 is operated to tilt the movable frame 2 and drum 4 downward by about 30 degrees as shown in FIG. 2A.

Then, the laundry is discharged onto the lower transfer conveyor 47.

In this case, the crosspiece 49 is provided in the front-rear direction and has an opening having approximately the same diameter as the drum, so that the laundry can fall smoothly.

Since the present invention has the above-described structure and operation, it exhibits the following effects.

1 Lid 17°29 on the front and back of a single tiltable drum 4
The drum 4 is tilted to open and close the front lid 17 to load and discharge the laundry, and the rear lid 29 is slid to drain the laundry. Even washing and draining can be done automatically, saving labor and increasing efficiency.

2. The drum 4 is a single unit, and water can be drained by sliding the rear lid 29, and the drum 4 and the front and rear lids 17.29 rotate as a unit, resulting in a simpler and safer washing machine. .

As described above, as shown in FIGS. 2A and 2B, the present invention pivots the upper part of the movable frame 2 in the longitudinal direction to the upper part of the fixed frame 1. A tilting mechanism 52 is provided to tilt the movable frame 2 using the section 3 as a fulcrum, and a single drum 4 is mounted within the movable frame 2 via a large number of guide rollers 5 and support rollers 12 provided on the movable frame 2 as shown in FIG. The morph 7 provided on the movable frame 2 and the drum 4 are connected by connecting members such as a belt 9 and a pulley 8, and the inner circumferential surface of the single drum 4 is provided with the morph 7 shown in FIG. A plurality of hollow crosspieces 49- are provided in the longitudinal direction as shown in FIG. 5 and FIG. link arm 2
The front lid 17 supported on the support plate 20 is provided with a front lid opening/closing mechanism 53 that opens and closes the opening as shown in FIG.
8 is fixedly installed, and a pipe 30 for externally supporting the rear lid 29 is provided on the movable frame 2 so as to be slidable in the longitudinal direction, so that the rear lid 29 can be opened and closed by sliding the pipe 30, as shown in FIG. After that, a drainage layer 37 is provided over the lid 29 and the rear opening circumferential surface of the drum 4 via a gasket 38, and a drainage port 39 is provided below the drainage layer 37, and a drainage port 39 is provided below the front side of the drum 4 for transferring laundry. A conveyor 47 is provided.

Therefore, by tilting the front side of the movable frame 2 downward and opening the front lid 17 of the drum 4 as shown in FIG. As shown in FIG. 2, the front opening of the drum 4 can be smoothly and automatically dropped onto the conveyor 47 through an opening having approximately the same diameter as the drum, and by tilting the front side of the moving frame 2 upward as shown in FIG. By moving the laundry to the front of the conveyor 47, it becomes easier to put the laundry into the drum 4, and by opening the rear lid 29 by sliding the pipe 30, it is possible to remove the laundry from between the rear end of the drum 4 and the rear lid 29 in the drainage layer 37. It has an excellent effect in that it allows drainage to fall without scattering to the outside, and automatically performs everything from loading the laundry to draining the laundry.

Furthermore, as shown in Japanese Patent Publication No. 51-45186 shown in Fig. 7, there is a risk that laundry may get caught in the boundary between the rotary drum and the fixed drum in a double drum body having a rotating drum inside a fixed drum. In order to prevent this, a wide inner flange is formed around the drum inlet, so that a small opening with a diameter of about 1/2 of the drum diameter is formed.

Therefore, even if the drum is tilted, the collar prevents the laundry from falling, and the worker has to reach out and pull out the laundry, which has become heavy due to moisture, which requires extremely hard labor. did.

Also, it is extremely difficult to load laundry through such a small opening, requiring hard labor by several male workers, and often resulting in back pain.

In this way, an opening having a diameter of 1/2 of the drum diameter has an area smaller than ]/3 of the drum area, resulting in extremely poor workability.

Furthermore, if the drum entrance is tilted upward, the entrance opening will be far away from the rear of the conveyor, making it difficult for workers to reach the loading chute, making it extremely difficult to load the laundry.

However, in the present invention, since the inlet opening has approximately the same diameter as the drum diameter, when the drum 4 is tilted as shown in FIG. Since the laundry is discharged straight onto the conveyor 47, the heavy labor of the worker, such as pulling out the laundry that has become heavy due to water content, is eliminated, and the loading of the laundry by a chute or the like can be done smoothly.

That is, when the entrance opening of the drum is tilted upward as shown in FIG. Therefore, the worker standing in front of the conveyor 47 can reach the entrance opening and completely push in the laundry thrown in from the chute, making the work smoother.

In addition, as disclosed in Japanese Utility Model Publication No. 29-9567, there is a system in which a front cover and a rear cover are fixed to a single drum, and the front cover and rear cover are pivotally connected to the fuselage by bearings while integral with the drum. This is a single drum held in a horizontal position, and laundry must be taken in and out through a small opening provided on the side of the drum.

In other words, male workers have to pull out heavy laundry containing moisture, which requires a great deal of effort, and the drainage is extremely incomplete as the rear lid remains integrated with the drum and drains water using a siphon. Dirty water remains, making it difficult to do clean laundry.

However, in the present invention, the laundry slides on the inner peripheral surface of the drum and is discharged straight down by tilting the drum 4, which eliminates the above-mentioned heavy labor.Moreover, since the rear cover 29 is separated from the drum 4 to drain the laundry, the laundry is completely drained at once. This is an excellent rotary drum type washing machine in which water can be drained while the drum rotates, and moreover, the drainage layer 37 prevents it from scattering outward, thereby efficiently performing sanitary washing.

Note that since a partition material such as punching metal 28 having water holes scattered therein is fixed to the rear end opening of the single drum 4, except for the rear end opening of the hollow crosspiece 49, When the lid 29 is pulled apart, the dirty water falls from the rear end opening of the hollow crosspiece 49 into the gap between the drum 4 and the rear lid 29 and is drained. Therefore, it will not be discharged.
