Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a washer-extractor suitable for commercial use. Conventional washer-extractors for commercial use include an inner shell that is disposed horizontally, and an inner shell that is housed and disposed horizontally. The outer shell is fixedly provided in a cantilevered state. The reason for adopting this posture is to obtain a washing effect when the laundry is lifted by the inner drum and then dropped to the lower part of the inner drum under its own weight. However, with such conventional washer-extractors, you have to open the door attached to the front of the outer shell and manually take the laundry in and out of the inner shell. It had the disadvantage of poor workability. Furthermore, since the posture of the conventional washer-extractor does not change, the movement of the laundry items during washing is standardized. For this reason, it is difficult for detergents, chemicals, etc. to penetrate into the items to be washed, and the washing time is long. Furthermore, since dehydration is carried out in a horizontal position, similar to washing, vibrations are likely to occur during dehydration, and it is difficult to rotate the inner barrel at a higher speed to increase the dehydration effect.

Moreover, in addition to the cantilever structure in which the outer shell is supported, there is a drawback that the bearing requires a strong bearing due to the fact that the load due to vibration acts on the bearing.

The present invention was proposed under the above circumstances, and its purpose is to facilitate the loading and unloading of laundry items, and to
To provide a washing and dehydrating machine which can improve the efficiency of washing and dewatering and can also suppress vibrations during dehydration.

That is, in the present invention, an outer shell housing an inner shell is rotatably supported with respect to a support frame in a direction in which the direction and height of its opening change, and the outer shell is arbitrarily rotated by a posture control mechanism. The present invention is characterized in that the inner and outer shells can be rotated to optimal orientations for loading and unloading items to be washed, washing, and dehydration.

Hereinafter, the present invention will be described with reference to an embodiment shown in the drawings.

1 in the figure is a support frame. This frame 1 is formed by attaching support plates 4, 4 to the left and right sides of a pedestal 2, respectively, via anti-vibration air springs S, S, and the support plates 4.4 have supporting portions 5 facing each other, respectively. It is provided. This embodiment shows a case where the supporting parts 5, 5 are made of bearings. Note that the bottom of the pedestal 2 has a rectangular frame shape so that the items to be washed can pass downward.

Further, reference numeral 6 in the figure represents an outer shell having an opening at one end and rotatably supported by the support frame 1 in the following manner. That is, the peripheral side wall of the outer shell 6 is provided with supported portions 7 that face each other in the radial direction, and by supporting these supported portions 7.7 on the supporting portions 5, 5, respectively, the outer shell 6 is It is supported by a support frame 1 so as to rotate in a direction in which the orientation and height of the opening change. This example wire supported part 7, 7
is a shaft protruding from the outer shell 6. However, in carrying out the present invention, contrary to this example II, a bearing to be supported is provided on the outer shell 6, and a bearing is provided on the support frame 1. It is also possible to provide a protruding shaft to support the outer shell 6. In addition, the outer shell 6 is the most preferable example of this embodiment.
Although the supporting part 5 and the supported part 1 may be provided diagonally to rotate the outer shell 6, the angle at which the support part 5 and the supported part 1 are tilted (that is, the supporting part 1 may be rotated in one plane) It is desirable that the angle [) between the axes of the portion 5 and the supported portion 1 be approximately 60° or less, for example.

The outer shell 6 supported in this manner can be rotated arbitrarily by a posture control machine *g provided between the outer shell 6 and the support frame 1. The attitude control mechanism 8 is shown in Figures 1 to 3.

There is. The motor 10 is equipped with a brake for holding the outer shell 6 in any desired position. The 100 rotations of the motor are controlled based on signals from a sensor such as a limit switch or a proximity switch (not shown) that detects the detected portion g1 provided internally in the driven gear 9. In addition, if necessary, a means for more reliably holding the outer shell 6t at any rotational position may be provided.

This means can be provided, for example, on the opposite side of the equipment provided with the above-mentioned attitude control mechanism 8, and includes a reciprocating stop (for example, an air cylinder red or a manually operated rod) provided with the support frame IK, and an external It is formed by a plurality of retaining parts (made of holes or holes and provided on a circle concentric with the supported part 1) provided on the plate material 6 that is integrated with the body 6, and these retainers mechanically prevent external movement.

3J is also a conveyor, a chute, and other unloading devices, which are installed and used above and below these main dehydrating washing machines, respectively.

Next, the case of washing and dehydrating laundry items will be explained.

First, the outer shell 6 is placed in a receiving position with its opening facing upward as shown in FIG. 6(4). This posture can be achieved by driving the air links 25 of the left and right door support mechanisms zz and zx to push out the slide members 14 and 14. After opening the door 21, the motor 10 of the posture control mechanism 8 is activated. Drive,
This is obtained by rotating the outer body d upward 90' from a horizontal position. In this state, the articles to be washed dropped from the carry-in device S2 are received into the inner barrel 11 through the opening.

Next, the door support mechanism 22. : After driving the air cylinder 26 of No. 12 and rotating the rotating arms MM and 1M to make the door 21 face directly above the opening of the inner and outer shells 6 and 120, the air cylinder j5 is driven to move the slide member 24. Pull in, door 2

) As shown in the figure, the attitude control mechanism 8 moves the outer trunk 6tl-
Take a horizontal position. In this state, detergent, chemical solution, and a predetermined amount of O water are introduced into the inner and outer shells, and then the washing motor 16 of the inner shell driver $15 is driven to rotate the inner shell 12 to wash the laundry. . Thereafter, water is drained, water is supplied again, and the rinsing motor l1t is driven while draining, and the inner barrel 12 is similarly rotated to perform rinsing.

During this washing process, the outer body posture can be made oblique by the posture control mechanism 8 if necessary. In this case, since the movement of the items to be washed is diversified, the penetration of detergents and medicinal materials into the items to be washed is promoted. Therefore, the swelling of the dirt is accelerated and the washing time can be significantly shortened.

After washing is completed, the water is drained, and then the posture control mechanism
As shown in the figure, after the outer shell 6 is placed in a vertical position, the dewatering motor 11 of the inner shell drive mechanism 15 is driven to remove the inner shell 1.
2 is rotated at high speed to dehydrate the items to be washed. Of course, in this case, the opening/closing body 27 is opened by driving the air cylinder 18. According to dewatering in such a vertical position, the shaft support 14 is subjected to a radial load as in the conventional case, and a thrust load is applied evenly, and the rotation of the inner cylinder 11 is affected by load fluctuations due to the weight of the items to be washed. Since there is almost no vibration, the inner shell 12 can be rotated at high speed and the generation of vibration can be suppressed. Therefore, the dewatering effect is enhanced and the dewatering time is shortened, and the shaft support 14 can be made of low-strength metal O, and since the direction of vibration is not vertical, there is no noticeable vibration. It is good to be able to reduce the

Next, after the dehydration is completed, the outer shell 6 as shown in FIG.
to the laundry discharge position. This posture is the door support mechanism 22.
22, first, when or before the outer shell C reaches the horizontal position, the door 21 is opened and the door 21 is retracted to a location other than below the outer shell C. Next, the posture control mechanism 8 rotates the outer shell 6 so that its opening faces downward. Then, the items to be washed in the inner barrel 12 are lowered by their own weight to the lower unloading mechanism 32.
is discharged to the top. In this case, if necessary, the inner shell 12
By slightly rotating the machine, you can unbalance the items being washed and discharge them more quickly.

In this manner, the treated items are sent to the next processing section such as a dryer by the carry-out mechanism.

Then, the next washing and dehydration process is performed again as shown in Figure 6 ■~(2) above.
This is accompanied by posture control.

In addition, in the above-mentioned embodiment, the widening door may be moved in parallel and pivotally attached so as to be able to move outward. In addition, the rotation range of the outer barrel is not necessarily limited to the rotation range in which the inner barrel can accept the falling items to be washed, and the items to be washed can fall from the inner barrel under its own weight, and the opening can be directed directly upward or downward. . In addition, in carrying out the present invention, the outer shell and the inner shell may be used as long as they do not go against the gist of the invention.

Inner body drive mechanism, door, supported part, supporting part, support frame,
Specific structure and shape of attitude control mechanism, etc.

It goes without saying that the position and the like are not limited to the one embodiment described above, and can be configured and implemented in various ways.

The gist of the present invention described above is the structure described in the claims above. Therefore, according to the present invention, the orientation and height of the opening of the outer shell can be adjusted by rotating the outer shell housing the inner shell using the attitude control mechanism, so that the laundry to be washed can be thrown into the inner shell. When discharging the laundry from the inner shell, the opening of the outer shell is directed upward, and when discharging the laundry from the inner shell, the opening of the outer shell is directed downward, allowing the laundry to fall under its own weight. Therefore, it is very easy to take in and take out the items to be washed, and automation thereof can be promoted. In addition, since the outer body can be held in a position other than horizontal during washing, the movement of the items to be washed can be diversified and washing efficiency can be improved. Since the inner cylinder can be rotated at high speed, the dewatering efficiency can be improved. Moreover, it has various excellent effects such as being able to reduce the load on the shaft supporting the inner shell by changing the outer shell posture during dewatering, and suppressing vibrations.
