Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a washing machine equipped with a hollow cylindrical horizontal rotary drum installed horizontally or almost horizontally at a slight angle, and equipped with a partition plate and stirring ribs. It was developed for the purpose of automating loading, transferring, and unloading.

In conventional washing machines, several devices have been devised and put into practical use that sequentially transfer the laundry between chambers in the rotating drum, but there is no device that automatically loads and takes out the laundry items. . If the loading and unloading of the items to be washed is performed manually, it is a heavy labor because the items to be washed containing water are heavy, and in addition, the apparatus is extremely inefficient. Moreover, because the rotating drum is divided into several chambers and washing with water, washing with detergent, washing with hot water, adding softener, etc. are carried out sequentially, conventional transfer devices result in a large loss of chemicals, and as a result, a large amount of wastewater treatment is required. It takes.

The present invention solves the above-mentioned problems at once with a simple device, and a substantially rectangular transfer plate penetrating both side walls and a partition wall of the rotating drum is installed at the virtual axis of the rotating drum with a rotating axis parallel to the virtual axis. The present invention is characterized in that the transfer plate can be moved left and right by a distance approximately equal to the distance between the partition walls, and that the transfer plate can be rotated by a pivot shaft.

Hereinafter, embodiments of the rotary drum type washing machine of the present invention will be specifically described with reference to the drawings.

Figure 1 is a cross-sectional view corresponding to line AA in Figure 2, and Figure 2 is a schematic diagram showing a cross-sectional view equivalent to section B-B in Figure 1.The structure can be explained using these figures as follows. It becomes like this. The rotating drum 1 is a horizontal hollow cylinder, and is provided with donut-shaped side walls 2, 2 and partition walls 3a, 3b, . In the figure, there are four rooms; for example, processing chambers 4a and 4b are used as a laundry room, processing room 4c is used as a hot water washing room, and processing room 4d is used as a washing room. Furthermore, it is optional to add a processing chamber and use it as a softener addition chamber or the like.

In addition, each processing chamber is provided with a stirring rib 5 extending along the diameter line of the drum and in the axial direction, in order to properly position the items to be washed in each processing chamber so that they are not piled up, and to ensure sufficient cleaning. One to several boards are provided. These stirring ribs 5 are arranged at mutually shifted positions in the circumferential direction of the rotating drum in each chamber to maintain drive balance.

The rotary drum 1 is driven to rotate by a conventional method such as gear transmission or chain transmission, in which the weight of the rotary drum is supported by rollers 6, and an outer peripheral gear is provided on the side wall 2 or the outer peripheral wall 7 of the drum.

The main body of a washing machine mainly consisting of a rotating drum having the above-mentioned structure is conventionally known, but in the present invention, there is a main body of a washing machine mainly consisting of a rotating drum having the above-described structure. A rectangular transfer plate 8 is provided. By installing this transfer plate 8, it was possible to automate the loading of items to be washed, the transfer and removal from each processing chamber.

As shown in FIGS. 1 and 2, the transfer plate 8 is installed in a donut-shaped through hole corresponding to the virtual axis of the rotating drum, and has a pivot shaft located at a slightly eccentric position diagonally downward to the right in FIG. 1. 9, it is supported so as to be pivotable from the vertical direction to the horizontal direction shown by the two-dot chain line,
It also has a structure in which it can be moved laterally between the position indicated by the solid line and the position indicated by the two-dot chain line in FIG.

Next, the function of the transfer plate 8 will be explained. 1st
In the vertical position of the transfer plate 8 shown in FIGS.
As the rotary drum 1 rotates clockwise, the items to be washed are stirred by the stirring ribs 5, then lifted upward, and as the stirring ribs 5 incline, the items to be washed fall back into the washing liquid.This operation is repeated. Washed while washing. The transfer plate 8 is vertical and does not prevent the objects to be washed from falling.

However, when the transfer plate 8 pivots around the pivot shaft 9 and assumes the horizontal position as shown in FIGS. The laundry 10 is dropped and supported on the transfer plate 8. Here, when the dirty object to be washed 10 is fed from the hopper 12 in FIG. 4, it is placed on the leftmost end of the transfer plate 8, and the objects to be washed in each processing chamber are also sequentially placed on the transfer plate 8 as shown in FIG. It will be posted as
As mentioned above, the processing chamber 4c is divided into a hot water washing room and a processing chamber 4d.
If this is assumed to be a washing room, the washed items are placed on the rightmost end of the transfer plate 8. Next, when the transfer plate 8 is moved in the direction of the arrow in the figure by approximately the same distance as the interval between the partition walls 3, each object to be washed is transferred by one processing chamber, and the dirty objects to be washed are transferred to the processing chamber 4a. , the washed laundry is sent out of the washing machine and transferred to the position shown by the two-dot chain line in FIG. 2, that is, to the vertical position by the transfer plate 8
By rotating the machine, the supply, movement, and removal of each item to be washed is completed. Thereafter, by repeating this operation, washing can be continued automatically without any effort.

The above-mentioned turning and left/right movement of the transfer plate 8 may be performed manually or may be electrically time-controlled and driven by a motor, and a known mechanism may be selected and applied as appropriate depending on the scale of the washing machine.

As described in detail above, the washing machine according to the present invention has a transfer plate installed therein, so that it is possible to continuously supply, transfer, and take out independent lumps to be washed. It has become possible to connect the process continuously with the bleaching or dyeing process and the subsequent drying and finishing processes, making it a great contribution to streamlining the processing process for fabric products.
