Each of the spring portions 24b is provided with a pressing portion 24c at the tip thereof, which protrudes in an arc surface shape toward the cylindrical peripheral wall 16a of the strainer 16. Then, in the strainer 16, between the spring portion 24b of the leaf spring 24 and the cylindrical peripheral wall 16a, the blade body 2 shown by a dotted line in FIG.
9 are arranged.

As shown in FIGS. 7 and 8, the blade body 29 is composed of a slender plate-shaped support column 33 and a plurality of blades 30 integrally formed with the one surface 33a thereof in a U-shape. The blade 30 is made up of a support portion 31 and a folded portion 32 formed by folding back the supporting portion 31. And
A handle 33b is integrally formed on the upper side of the column 33 in the figure. On the other hand, as shown in FIG. 9, the folded-back portion 32 is formed by bending with the same curvature as the inner surface 16d of the peripheral wall of the strainer 16, and the tip a side of the folded-back portion 32 is strainer 16 side.
Is gradually increased toward the downstream side in the rotation direction (direction of arrow A in FIG. 9). Then, the plurality of folded-back portions 32 are held in parallel with each other at the same intervals and provided in multiple stages.

However, such a blade body 29 is
Although shown by a dotted line in FIG. 6, as shown in FIG.
The pressing portion 24c of the leaf spring 24 is pressed against and urged, and the edge 32a of the folded portion 32 is pressed against the inner surface 16d of the peripheral wall of the strainer 16. Then, the blade body 29 is attached to the other surface 33 of the column 33 opposite to the one surface 33a.
The c is abutted against the abutting portion 25e, and the lid member 25 is replaceably fitted.

By the way, as shown in FIG. 10, each blade 30 has a thickness t of the edge 32a of the folded-back portion 32.
Is formed thinner than the thickness of other portions of the blade 30. In addition, the width D of the upper surface 32b of the folded portion 32a
Is formed to be a certain width or less, for example, a narrow width of 6 mm or less.

Further, in each blade 30, as shown in FIG. 9, a contact surface c of an edge 32a which contacts the inner surface 16d of the peripheral wall is formed in an arcuate surface on the outer circumference of the folded base portion b opposite to the tip a of the folded portion 32. On the other hand, the garbage guide surface d on the side not contacting the inner surface 16d of the peripheral wall is formed as a flat surface, and the angle θ formed by the garbage guide surface d and the contact surface c is formed as an acute angle.

Referring now to FIG. 2, sink 10 of the sink
When the garbage generated in 1 is discharged from the drain port 10a together with water, the garbage enters the disposer 11. Then, it is crushed by the disposer 11, and the crushed raw garbage flows out through the drainage pipe 12 and is put into the strainer 16 of the garbage treatment device 13 according to the present invention.

Thus, the high speed rotation of the strainer 16 driven by the motor 17 imparts a centrifugal force to the raw dust contained in the strainer 16 and attaches it to the inner surface 16d of the peripheral wall of the strainer 16. Then, it is dehydrated by centrifugal force, and the water generated by the dehydration is put into the strainer storage chamber 15 through a plurality of small holes 16e (see FIG. 6) provided in the cylindrical peripheral wall 16a of the strainer 16 and drained to the outside through the drainage channel 19.

On the other hand, the raw garbage after dehydration is strainer 16
Edge 32 of the blade 30 that adheres to the inner surface 16d of the peripheral wall of the blade 30 and presses the attached raw dust against the inner surface 16d of the peripheral wall.
scrape with a. Then, the scraped scraps are guided by the upper surface 32b of the folded-back portion 32 and sequentially pushed upward.

At this time, since the edge 32a which is pressed against the inner surface 16d of the peripheral wall has a small thickness t and is elongated, the biasing force of the leaf spring 24 is concentrated on the edge 32a and the edge 32a is concentrated.
Is strongly pressed against the inner surface 16d of the peripheral wall to effectively scrape off the garbage. Further, the edge 32a has an inner surface 16d on the peripheral wall.
The area pressed against the edge is relatively small, so the edge 3
The entire 2a is closely attached to the inner surface 16d of the peripheral wall without any gap, thereby preventing the foreign matter from being caught between the edge 32a and the inner surface 16d of the peripheral wall to cause clogging, and also prevent defective dehydration. Further, the folded portion 32a of the blade 30
Since the upper surface 32b is formed to have a narrow width, it is possible to prevent raw dust from staying on the upper surface 32b and prevent clogging due to the stay of the raw dust. Furthermore, since the angle θ formed by the contact surface c of the edge 32a and the garbage guide surface d in the folded base portion b of the blade 30 is formed to be an acute angle,
The garbage near the folding base b is guided by the garbage guide surface d,
The raw dust is sandwiched between the edge 32a and the inner surface 16d of the peripheral wall to prevent clogging.

Then, the garbage collected by pushing upward on the upper surface 32b of the folded portion 32 is finally strainer 1.
It is discharged from the upper opening 16b of the No. 6 into the recovery passage 20. The raw dust discharged to the collection passage 20 is transferred to the collection chamber 22 while being prevented from adhering to the inner surface of the collection passage 20 by the mesh member 21, and is put into, for example, a bag in the collection chamber 22. Then, the bag or the like is properly taken out and replaced with a new one.

When the blade body 29 is replaced with a new one, for example, because the blade 30 is worn, the blade body 29 is held by the grip member 33b.
Is taken out from the strainer 16 through the window 25b. Then, install the new blade body 29 through the window 25b to the strainer 1
It is put in 6 and fitted to the lid member 25.

In the illustrated embodiment described above, as shown in FIG. 10, the thick portion 32c of the folded portion 32 of the blade 30 is formed in a substantially rectangular cross section. However, instead of this, the side surface e of the thick portion 32c on the edge 32a side may be formed as an inclined surface as shown in FIG. 11 (a), or as shown in FIG. You may form in a concave shape. Instead of the example of FIG. 10, the corner f on the side opposite to the edge 32a may be chamfered planarly as shown in FIG. 11C, or may be rounded as shown in FIG. You may chamfer to the attached shape.

In the illustrated embodiment described above, a plurality of blades 30 having the same length are provided in parallel, and the amount of pushing up the raw dust on each blade 30 is the same. However, the plurality of blades 30 need not be equal in length, need not be parallel, and may be pushed up differently by each blade 30.

Further, a plurality of blades 30 are provided in the same position in the rotation direction A of the strainer 16 in a multi-layered manner. However, it need not be provided at the same position in the rotation direction, and may be provided separately at a plurality of positions in the rotation direction. In this case as well, it is naturally necessary that the upper blade 30 partially overlaps the area for pushing up the garbage. If they do not overlap, the garbage in the non-overlapped portions will remain linearly on the inner surface 16d of the peripheral wall of the strainer 16.

[0031]

Therefore, in the garbage disposal according to the present invention, since the blade is pressed against the inner surface of the peripheral wall of the strainer, it is possible to cleanly remove the garbage such as garbage adhered to the inner surface of the peripheral wall. Further, since this blade is configured to be fitted in the window of the lid member to be put on the strainer and urged by the elastic member to press against the inner surface of the peripheral wall of the strainer to hold it, even if the strainer is installed at an inclination, Also, the blade is always pressed against the inner surface of the peripheral wall of the strainer in accordance with the inclination, whereby the garbage such as garbage can be removed more cleanly.

According to the second aspect of the invention, since the blade is replaceably fitted to the lid member,
The blades can be easily replaced if needed.

According to the third aspect of the present invention, since the thickness of the edge of the blade that comes into contact with the inner surface of the peripheral wall of the strainer is made thinner than the thickness of other portions of the blade, the edge presses against the inner surface of the peripheral wall. The area becomes smaller, whereby the entire edge can be closely adhered to the inner surface of the peripheral wall without any gap, and the garbage can be prevented from being caught between the edge and the inner surface of the peripheral wall to cause clogging and further prevent defective dehydration. .

According to the fourth aspect of the present invention, the blade is made of a supporting portion and a folded-back portion formed by folding back the blade at an acute angle, and the folded-back portion has the same curvature as the inner surface of the peripheral wall of the strainer. The edge is brought into close contact with the inner surface of the peripheral wall and pressed against it, whereby it is possible to prevent kitchen waste from intruding and being caught between the edge and the inner surface of the peripheral wall and causing clogging. .
