The Y axis added to the conventional example shown in FIG. 3 is the conveying direction of the belt conveyor 5 and is also the center line in the plan view.
In the grooved receiving plate 6 of the conventional example, a number of parallel longitudinal grooves 7 are parallel to the Y-axis, causing the following problems.
FIG. 3C is a partially enlarged view of a cross section taken along a plane orthogonal to the Y axis.

In FIG. 3C, the parallel longitudinal grooves 7 are perpendicular to the paper surface, and the running direction of the conveyor belt 5 'is also perpendicular to the paper surface.
For this reason, the locations where the conveyor belt 5 'touches the edges of the parallel longitudinal grooves 7 (locations indicated by arrows a, b, c, d) are always the same.
In consideration of the above-mentioned place, in this cross-sectional view, it is drawn as a point indicated by an arrow.
Since a shearing force is constantly applied along this fixed line, a crack is formed relatively early and the useful life of the conveyor belt is shortened.

  The present invention has been made in view of the circumstances described above, and the purpose of the present invention is to improve the grooved receiving plate of the continuous dehydrator and to extend the useful life of the conveyor belt dramatically. is there.

The basic principle of the present invention created to achieve the above object will be briefly described with reference to FIG. 1 corresponding to one embodiment thereof.
As described above with reference to FIG. 3A, the conveyor belt of the belt conveyor 5 runs in the Y-axis direction. Since the parallel vertical grooves 7 of the conventional example are parallel to the Y axis, the shearing force is applied to a certain portion in consideration of the present invention (FIGS. 1A and 1B). A diagonally inclined parallel inclined groove 8 is provided.
(Note) One of the parallel inclined grooves 8 intersects the Y axis at an angle θ.
However, the multiple parallel inclined grooves 8 are parallel to each other.
Whether parallel or oblique should be understood by distinguishing between “relationship between grooves” and “relationship with respect to the Y-axis”.

As a specific configuration based on the above-described principle, a grooved receiving plate for a dehydrator according to the invention of claim 1 (see also FIG. 1 and FIG. 3) includes a basket (1) for storing laundry (2), In the grooved receiving plate (6) provided in the dehydrator disposed on the belt of the belt conveyor (5), the pressure plate (3) for squeezing the laundry,
Assuming a Y-axis parallel to the conveying direction of the belt conveyor,
Each of the multiple grooves (8) provided in the grooved receiving plate (6) is inclined with respect to the Y axis.

  The structure of the grooved receiving plate for a dehydrator according to the invention of claim 2 is such that the plurality of grooves are parallel to each other (see FIG. 1B) in addition to the constituent features of the invention of claim 1. In addition, the inclination angle between each groove and the Y axis is 90 degrees.

  The structure of the grooved receiving plate for the dehydrator according to the invention of claim 3 is the same as that of the invention of claim 1 (see FIG. 1C), wherein the plurality of grooves are symmetrical with respect to the Y axis. It is arranged.

  According to a fourth aspect of the present invention, there is provided a grooved receiving plate for a dehydrator (see FIG. 1 (D)) in addition to the constituent features of the first aspect of the present invention. It is characterized by being.

  When the grooved receiving plate for a dehydrator according to the invention of claim 1 is applied, each of a large number of grooves provided in the grooved receiving plate is inclined with respect to the Y axis. The relational position between the “traveling conveyor belt” and the “groove inclined with respect to the Y axis” always changes. For this reason, there is no possibility that a specific part of the conveyor belt is worn out early.

  In the invention of claim 2, the inclination angle in the invention of claim 1 is 90 degrees as a limit value. Therefore, there is no fear of damaging the function and effect of Claim 1, and the drainage of the dewatering operation can be discharged to the side of the belt conveyor.

  In the invention of claim 3, as an application of the invention of claim 1, the inclination angle of the groove is set symmetrically. Therefore, there is no risk of damaging the function and effect of claim 1, and since the groove shape is symmetric, the strength distribution of the grooved receiving plate is also equal to the left and right, and the draining action is equally performed to the left and right.

As an application of the invention of claim 4 as an application of the invention of claim 1, a curved groove is formed.
Therefore, there is no risk of impairing the function and effect of claim 1, and the strength distribution of the grooved receiving plate is uniform. That is, there is no directionality such as being easy to bend or break along the Y axis. For this reason, the pressing force of the dehydrator pressure plate is evenly supported to enable a stable dehydrating action.

FIG. 1 (A) is a schematic plan view of a dehydrator provided with one embodiment of a grooved receiving plate according to the present invention, and corresponds to FIG. 3 (A) depicting a conventional example.
Next, a different point of FIG. 1A from that of FIG. 3A, that is, a matter improved by applying the present invention will be described.
Although the parallel vertical grooves 7 in the conventional example are parallel to the Y axis, the parallel inclined grooves 8 of the present embodiment are inclined by an angle θ with respect to the Y axis.

Although the grooved receiving plate 6 is a stationary member, the conveyor belt of the belt conveyor 5 runs intermittently in the Y-axis direction. That is, when the dewatering operation is performed as shown in FIG. 2 (A), the belt conveyor is stopped, and when the dewatering operation is performed once as shown in FIG. 2 (B), the belt conveyor is activated and the laundry 2 Send out.
In the embodiment of FIG. 1A, since the parallel inclined groove 8 is inclined with respect to the Y axis, it does not happen that “a specific portion of the conveyor belt stops facing the groove (or mountain)”. .

Consider a case where an arbitrary point P on the conveyor belt 5 'repeatedly travels and stops in the direction of the arrow.
In the figure, the arrow indicating the traveling direction is downward, but the following description is the same even if it is upward. However, the traveling direction is always parallel to the Y axis.
For this reason, the imaginary point P described above crosses over a number of inclined grooves 8 alternately on the grooves and on the land.

When the running conveyor belt stops, it is a coincidence whether it is located on the groove or on the land. That is, since no other control is applied to the stop operation of the conveyor belt, it is completely unknown whether the virtual point P stops on the groove portion or on the land portion.
Based on common sense, there is a 50% possibility of stopping on the groove part and a 50% possibility of stopping on the land part (it is possible to make some deviation by chance). What is important here is that "any point of the conveyor belt does not always stop facing a specific part of the grooved receiving plate".

Here, when the reason why the grooved backing plate of the conventional example damaged the conveyor belt is reconfirmed (see FIG. 3C), every time the belt conveyor stops, a certain part of the conveyor belt becomes grooved. This is because it touches a specific portion illustrated by arrows a, b, c, and d corresponding to the shore of the land portion of the receiving plate 6.
In contrast to this, in the present embodiment, as described above, “any point of the conveyor belt does not always stop facing a specific portion of the grooved receiving plate” is eliminated. Is prevented in advance and completely.

FIG. 1B shows an embodiment different from the above, and is a plan view illustrating one grooved receiving plate 6.
When the inclination angle θ of the parallel inclined groove 8 in FIG. 1A is 90 degrees as the limit value, the parallel horizontal groove 9 as shown in FIG. 1B is obtained. Since this is a kind of form of the parallel longitudinal grooves 7 in the above-described embodiment of FIG. 1A, the operation and effects in the above-described embodiment are not hindered.
In addition, since a large number of grooves are formed perpendicular to the Y axis, the strength when supported by the ridges in the Y axis direction is high, and bending is also small.

FIG. 1C shows a different embodiment from the above, and is a plan view illustrating one grooved receiving plate 6.
In the figure, the upper side of the rectangular grooved receiving plate 6 is equally divided (16 equal parts in this example) to form a groove having an angle θ with respect to the Y axis, and the above-mentioned angle between the left and right sides of the Y axis. When the inclination direction of θ is reversed, the symmetrical inclined groove 10 shown in FIG.
If comprised in this way, since it has the same intensity | strength in a Y-axis direction and a X-axis direction, there is little bending, and a support is easy. As a result, the grooved receiving plate 6 can be reduced in size and weight, which is effective for reducing the manufacturing cost.

FIG. 1 (D) shows a different embodiment from the above, and is a plan view depicting one grooved receiving plate 6.
In this example, each of a large number of grooves is formed in the curved groove 11.
The curved groove 11 of this example is symmetric with respect to the Y axis, but is not necessarily limited to symmetric.
As can be easily understood from the operation and effect in the embodiment shown in FIG. 1A, in short, “the groove is not parallel to the Y axis” is a point for preventing the conveyor belt from being damaged.

Therefore, if the groove of the grooved receiving plate 6 is a curved line, the curved groove cannot be parallel to the Y axis, so there is no possibility of damaging the conveyor belt.
When the curved groove is provided, even if there is a portion that is partially parallel to the Y axis, the object is achieved unless the majority is parallel to the Y axis.
As is clear from these considerations, even if the gap dimension between the grooves is not constant, or even if the grooves are intermittent, most of the grooves are not parallel to the Y axis and belong to the technical scope of the present invention. Is.
