Description

The present invention relates to a rotating plate for a disposer for pulverizing cocoons generated in a kitchen or the like.

The disposer connected to the drain of the sink receives the dredging thrown on a rotating plate provided at the bottom of the crushing chamber, crushes this rotating plate with an electric motor and crushes it with an impact hammer attached to the upper surface, A discharge pipe connected to the discharge chamber that surrounds the rotary plate and pulverizes it by finely shearing and grinding between a fixed blade provided on the inner wall of the bottom of the crushing chamber and the outer periphery of the rotary plate, and dropping into the discharge chamber below the rotary plate together with water From the water to the sewer pipe.

The rotating plate of such a disposer is generally made by punching a stainless steel plate into a circle, and a swing hammer that is freely attached to the rotating plate with a pin is used as an impact hammer, but the thickness of the rotating plate is small. Disposers often have a thickness of about 1.5 to 2 mm, and a reinforcing plate is stacked on the lower surface of the rotating plate to maintain strength, and this reinforcing plate is used as a mounting plate for a swing hammer. (For example, Patent Document 1, Patent Document 2, Patent Document 3, etc.)
Further, instead of the swing hammer, a fixed hammer that is fixed to the rotating plate and crushes the ridges may be used. (Patent Document 4)

JP 2003-110072 (see paragraph No. 0004) JP 2001-179116 A (see paragraph 0016) Japanese Patent Laying-Open No. 2004-243241 (see paragraph number 0006) JP-A-10-296108 (see paragraph 0006)

When a swing hammer is used as a hammer for the rotary plate, there is a gap between the swing hammer and the rotary plate, and small pieces such as bones are stuck in this gap, and the balance of the rotary plate is lost. It is a cause of noise.
Further, although the fixed hammer has a separate hammer piece fixed to the rotating plate, it is considered that the fixed hammer is formed by cutting and raising the peripheral edge of the rotating plate because the mounting is troublesome. However, the thickness of the rotating plate itself is reduced to reduce the flywheel effect, the thickness of the fixed hammer is also reduced, the life against wear due to crushing is short, and the entire rotating plate must be replaced to replace the hammer. It was.
The present invention provides a disposer in which the wear of a fixed hammer formed by cutting and raising a rotating plate is reduced, and the life of the rotating plate is extended.

For this reason, the invention of claim 1 is provided with a low first fixing hammer in which a reinforcing plate thicker than the rotating plate is superposed on the lower surface of the rotating plate and the rotating plate itself is cut and raised upward at a symmetrical position of the rotating plate periphery. The reinforcing plate itself is cut and raised at the symmetrical position of the reinforcing plate to form a second fixed hammer which is raised in accordance with the fixed blade, and the second fixed hammer protrudes from the notch groove provided on the periphery of the rotating plate onto the rotating plate. I am letting.
According to a second aspect of the present invention, an impeller having a mounting plate is attached to the lower surface of the rotating plate, and the gap after the first fixed hammer is cut and raised is closed by the impeller mounting plate attached to the lower surface of the rotating plate. , Preventing the fall of the kite from the gap.
According to a third aspect of the present invention, an impeller having a mounting plate on the lower surface of the rotating plate is mounted in front of the first fixed hammer with respect to the rotating direction of the rotating plate, and the outer peripheral portion of the impeller mounting plate is slightly The mounting plate removes the gap after the first fixed hammer has been cut and raised, leaving a slight through-hole in the outer periphery to prevent the spear from falling through the rear part of the impeller. Using the negative pressure, the soot remaining on the fixed blade around the rotating plate is sucked and discharged.

As described above, the present invention includes the low first fixed hammer cut and raised from the rotary plate on the rotary plate and the high second fixed hammer cut and raised the thicker reinforcing plate than the rotary plate, and the number of hammers is increased. While increasing the crushing effect, it is not necessary to attach a separate hammer piece because it is raised from the rotating plate and the reinforcing plate itself, making it easy to form a fixed hammer, and the thin first fixed hammer has a small crushing surface Therefore, the scissors are mainly crushed by the second fixed hammer with a wide crushing surface, and the wear of the first fixed hammer can be reduced, and the second fixed hammer is thick and wear-resistant. The effect that the life of the entire rotating plate can be extended is obtained.
In addition, by attaching the impeller having a mounting plate on the lower surface of the rotating plate, the gap after the first fixed hammer is cut and raised by the impeller mounting plate can be closed to prevent the fall of the spear from the gap. The impeller is mounted in front of the first fixed hammer with respect to the rotation direction of the rotating plate, and the gap after the first fixed hammer is cut and raised by the impeller mounting plate is blocked while leaving a slight through portion on the outer peripheral portion. Thus, the effect of sucking and discharging the soot remaining on the fixed blade around the rotating plate by using the negative pressure at the rear of the impeller can be obtained.

A reinforcing plate thicker than the rotating plate superimposed on the lower surface of the rotating plate is provided, a lower first fixed hammer obtained by cutting and raising the rotating plate upward at a symmetrical position on the periphery of the rotating plate, and a reinforcing plate at a symmetrical position of the reinforcing plate. There is provided a high second fixed hammer which is cut and raised upward and protrudes from a notch groove provided at the periphery of the rotating plate.
Further, in the rotary plate for attaching the impeller to the lower surface, the gap after the first fixed hammer is cut and raised by the impeller attachment plate is closed.

Hereinafter, the drawings will be described.
1 to 4, 1 is a crushing chamber, 2 is a rotating plate that is provided at the bottom of the crushing chamber 1 and is rotated by a motor 3 by receiving a flaw, and uses a stainless steel plate having a thickness of 2 mm. Reference numeral 4 denotes a reinforcing plate which is superposed on the lower surface of the rotating plate 2 using a stainless steel plate having a thickness of 3 mm. Reference numeral 5 denotes a first fixed hammer formed by cutting and raising the symmetrical position of the periphery of the rotating plate 2 and bending it upward, and is lower than the height of the fixed blade 12 surrounding the rotating plate 2. 6 is a notch groove provided at a position 90 degrees offset from the first fixed hammer 5 of the rotary plate 2, 7 is a shaft hole, 8 is a protrusion insertion hole, and 9 is a symmetrical position of the reinforcing plate 4. A second fixed hammer that is cut and raised and bent is inserted into the notch groove 6 of the rotary plate 2 and protrudes higher than the first fixed hammer 5 on the rotary plate in accordance with the fixed blade 12. 10 is a shaft hole of the reinforcing plate 4, and 11 is an engaging projection cut and raised on both sides of the shaft hole 10, which is projected through the projection insertion hole 8, and a handle (not shown) is engaged when the rotating plate 2 is manually rotated. . 13 is a discharge chamber below the rotating plate, and 14 is a discharge pipe connected to the discharge chamber.

The rotating plate 2 attached to the rotating shaft of the motor 3 is provided with a low first fixed hammer 5 obtained by bending the rotating plate itself and a high second fixed hammer 9 formed by bending the reinforcing plate 4 at symmetrical positions. The pestle placed in the crushing chamber 1 receives the centrifugal force by the rotation of the rotating plate 2 and hits the crushing chamber wall, and the first fixed hammer 5 and the second fixed hammer on the rotating plate. However, since the first fixed hammer 5 is low, the side area is small, and the second fixed hammer 9 is high and the side area is large. For this reason, the contact surface with the scissors is different, particularly a large scissors are crushed by the second fixed hammer 9 with a wide contact surface, and the first fixed hammer 5 with a small contact surface crushes a relatively small scissors, The wear of the first fixed hammer 5 due to the impact with the heel is small, and the wear of the second fixed hammer 9 is increased.
However, the second fixed hammer 9 is formed of the thick reinforcing plate 4, has a long life against wear, and can extend the life of the entire rotating plate.

The reinforcing plate 4 may be superposed on the entire lower surface of the rotating plate 2, and the thickness, the shape of the hammer, the angular position between the hammers, etc. are not limited to the embodiment shown in the figure.

FIG. 5 is an exploded view showing another embodiment, in which the same reference numerals are assigned to the same parts as in FIG. 1, and 15 is an impeller attached to the position of the first fixed hammer 5, which is applied to the lower surface of the rotating plate 2. The mounting plate 16 is provided, and is fixed to the lower surface of the rotating plate 2 with a rivet (not shown). The impellers at other positions are not shown.
When the impeller 15 is attached, the attachment plate 16 is attached to the position of the gap 17 after the first fixed hammer 5 is cut and raised. Therefore, it is possible to prevent the gap 17 from being blocked from below by the mounting plate 16, eliminating the gap 17 and dropping the wrinkles on the rotating plate 2 into the discharge chamber 13 without being crushed by the fixed blade 12.

6 and 7, the impeller 15 attached to the position of the first fixed hammer 5 is attached to a position in front of the first fixed hammer 5 with respect to the rotation direction of the rotary plate 2 indicated by an arrow. A slight notch 18 is provided in the outer peripheral portion of the impeller mounting plate 16, and when attached to the rotating plate 2, the mounting plate 16 forms a small portion on the outer peripheral portion with a gap behind the first fixed hammer 5. The remaining part is closed and a through-hole 19 of the rotating plate that opens to the outer periphery is formed.
For this reason, due to the rotation of the impeller, the back side of the impeller becomes negative pressure, and the air in the crushing chamber 1 is sucked into the discharge chamber 13 through the penetrating portion 19 and adheres to the fixed blade 12 in the crushing chamber 1 by this flow. Aspirate the sputum.
