Description

TECHNICAL FIELD The present invention relates to a disposer for pulverizing food residues, leftover food, etc. and discharging them into sewage.

Conventionally, a disposer is known as a device for treating kitchen waste and leftover food generated by cooking by finely pulverizing them and discharging them to the sewage side through a treatment tank or the like.
Briefly explaining the configuration of the disposer, it is equipped with a dumping port for dumping garbage in the sink of the sink,
Garbage, leftover food, etc. thrown from this dumping port are thrown into the disposer main body, pulverized, and then discharged from the discharge port to the sewage side via a treatment tank or the like.
The disposer main body is provided with a crushing chamber below the dumping port for containing and crushing the garbage dumped from the dumping port, and a discharge port for discharging the garbage crushed in the crushing chamber to the downstream side. .
Further, the crushing chamber has a substantially cylindrical shape, and an inlet at the upper end thereof for throwing garbage from the dumping port into the crushing chamber, a fixed blade fixed along the peripheral edge on the inner surface of the crushing chamber, and a crushing device. A rotating disk is provided below the chamber and rotates about the central axis of the grinding chamber in the grinding chamber, and a rotating blade is provided on the rotating disk and cuts kitchen waste and kitchen waste by sandwiching it with a fixed blade and grinding it. The pulverized kitchen waste and garbage are discharged downward through the gap between the fixed blade and the rotating disk, and discharged from the discharge port.
The fixed blade is a ring body made of a metal material, and has a slit extending obliquely downward on the inner surface. and raw garbage are pulverized.
When pulverizing, water is supplied from the dumping port. Specifically, by setting a perforated plate member equipped with multiple small-diameter water passage holes in the dumping port, and then supplying water to the dumping port from a water tap, etc., the water passage port of the perforated member Water can be supplied into the crushing chamber through the inlet and the inlet. This water supply acts to discharge the crushed kitchen waste, garbage, etc. in the crushing chamber to the outlet.
Further, the pulverized kitchen waste, garbage, etc. is discharged from the pulverizing chamber through the slit of the fixed blade and downward from the fixed blade and the rotating disk toward the discharge port.

In the above disposer, placing a perforated plate member in the disposal port when the disposer is in operation is dangerous if the user or the like inserts his or her hand into the crushing chamber of the disposer from the disposal port. This is because it is necessary to prevent backflow from the dumping port due to the impact caused by the rotation of the rotating disk. In addition, if the dumping port is completely blocked by the lid, it is impossible to supply water through the dumping port. It is possible to supply water to the grinding chamber while preventing backflow to the mouth side.

The rotating disk 5 is rotated at high speed by a motor, and as described above, it is possible to reliably pulverize even hard kitchen waste and garbage.
As is clear from FIGS. 1 and 2, in this embodiment, from the dumping port 1a to the charging port 2a of the crushing chamber 2 is formed perpendicular to the horizontal plane, that is, in the vertical direction.
The pulverized kitchen waste and garbage are discharged downward through a slit of the fixed blade 3, which will be described later, and discharged from the discharge port 1b.
The fixed blade 3 is a ring body made of a metal material, and is provided with a slit extending obliquely downward on the inner surface, so that the kitchen waste, garbage, etc., are caught between the slit portion and the rotary blade 4 to be scraped off. Kitchen waste and kitchen waste are pulverized. Further, the crushed kitchen waste and garbage are discharged downward from the slit of the fixed blade 3 and discharged from the crushing chamber 2 toward the discharge port 1b.
A connecting pipe 6 connects the dumping port 1a and the charging port 2a.
Further, the dumping port 1a is provided with a perforated plate member M arranged so as to cover the dumping port 1a. The disposal port 1a is provided with a sensor, and for safety, the disposer is not driven unless the disposal port 1a is blocked by the perforated plate member M.
Specifically, as shown in FIGS. 3 and 4, the perforated plate member M is composed of a substantially cylindrical side surface portion and a bottom surface portion that covers the lower end portion and is flat and arranged horizontally during use. It is a constructed member, and has a handle portion M1 on the inner diameter side from a part of its upper edge, and a magnetic body (not shown) corresponding to the sensor on the side portion where the handle portion M1 is located.
Further, a side surface water passage port M2 is provided on the side surface of the perforated plate member M, and a bottom surface water passage port M3 is provided on the bottom surface of the perforated plate member M, respectively.
The side water passage M2 is composed of a plurality of 1.4 mm square openings regularly provided in the horizontal direction.
The bottom water passage M3 is composed of a plurality of regularly provided openings of 1.4 mm square in plan view, and each opening is provided at an angle of about 45 degrees with respect to the horizontal direction. The direction of this opening is provided in the direction toward the water discharging portion Q from the bottom to the top.
In addition, the thickness of the bottom surface of the perforated plate member M is 2 mm or more. The opening on the lower surface cannot be seen from the opening. In FIG. 5, the solid line portion is the portion of the bottom water passage M3 that is visible in plan view, and the broken line portion is the portion of the bottom surface water passage M3 that is hidden behind the bottom surface of the perforated plate member M and cannot be seen. In addition, since it is almost impossible to see the openings on the outer side and the inner diameter side of the side water passage M2 in a plan view, in the perforated plate member M of the present embodiment, the water passage through which the downward direction can be seen in a plan view is the side water passage. It does not exist in either M2 or the bottom water passage M3.
Further, as described above, the disposal port 1a is provided with a sensor, and for safety, the perforated plate member M is arranged in the disposal port 1a, and unless the sensor detects the magnetic material of the perforated plate member M, the disposer configured not to drive.
In this embodiment, the position where the magnetic material of the perforated plate member M corresponds to the sensor of the dumping port 1a means that the handle portion M1 of the perforated plate member M is arranged in the opposite direction of the water tap Q.
Further, as shown in FIG. 2, the crushing chamber 2 of the present embodiment is provided on the inner surface of the crushing chamber 2, starting from the inlet 2a, on the inner surface of the crushing chamber 2, the rotating blade 4 or the fixed blade 3 Three inclined surfaces 2c continuous up to a height position are provided so as to form a rotationally symmetrical shape centering on the inlet 2a in a plan view.
As shown in FIGS. 2 and 3, a projecting portion 2b is provided on the inner surface of the crushing chamber 2, and an inclined surface 2c is provided on the lower surface of the projecting portion 2b. The inclined surface 2c is slanted in a direction in which kitchen garbage, garbage, etc., are directed downward along the inclined surface 2c when the garbage, garbage, etc., are directed in the rotating direction of the turntable 5.例文帳に追加For this reason, when the disposer is activated and the garbage and food waste are rotated in the crushing chamber 2 by the rotation of the turntable 5, they collide with the inclined surface 2c and fall downward along the inclined surface 2c. becomes.
The drain connecting pipe 7 has an upstream end connected to the discharge port 1b of the disposer, and a downstream end connected to an underfloor pipe leading to the sewer side.

A method of using the disposer of the first embodiment will be described below.
When using the disposer configured as described above, kitchen waste and garbage are first thrown out from the dumping port 1a. Garbage, food waste, etc. thrown from the dumping port 1a are thrown into the crushing chamber 2 from the throwing port 2a through the connecting pipe 6. As shown in FIG.
Next, the perforated plate member M is arranged in the dumping port 1a.
At this time, the magnetic material of the perforated plate member M is arranged at a position corresponding to the sensor of the dumping port 1a. As described above, in this embodiment, the position where the magnetic material of the perforated plate member M corresponds to the sensor of the dumping port 1a is the state in which the handle portion M1 of the perforated plate member M is arranged in the opposite direction of the water tap Q. be. Therefore, when the disposer is used, the bottom water passage port M3 of the perforated plate member M is arranged in the dumping port 1a so as to be inclined from the bottom to the top in the direction of the faucet Q, which is the direction in which the user is not present. be.
From this state, when the water tap Q is opened and the disposer is operated while supplying water into the sink S, the rotary disc 5 rotates, and the kitchen waste, garbage, etc. are thrown from the center of the crushing chamber 2 to the outer peripheral side (toward the inner surface of the crushing chamber 2) in a vortex. For this reason, the kitchen waste and kitchen garbage sandwiched between the rotating blade 4 and the fixed blade 3 are pulverized so as to be ground, and part of it flows downward through the slit or the gap between the rotating plate 5 and the fixed blade 3. Ejected.
The mashed kitchen waste and garbage are pressed against the inner surface of the comminution chamber 2 by the centrifugal force caused by the rotation of the rotary disc 5 . Also, at this time, since the garbage and garbage are moving due to the biasing force of the rotary disc 5, they move along the inner surface of the grinding chamber 2 in accordance with the rotation direction of the rotary disc 5.
Here, the inclined surface 2c extends from the input port 2a to the rotary blade 4 or the fixed blade 3 regardless of the position from the input port 2a to the rotary blade 4 or the fixed blade 3. Since it is provided at the position, kitchen waste and garbage always hit the inclined surface 2c, move downward along the inclined surface 2c, are guided to the positions of the rotary blade 4 and the fixed blade 3, and are pulverized. That is, in order to increase the efficiency of pulverization by the rotary blade 4 and the fixed blade 3, even when the rotary disc 5 is rotated at high speed, the inclined surface 2c prevents the kitchen waste and kitchen garbage from jumping, and the rotary blade 4 and the fixed blade 3 are prevented from scattering. Since it is guided, it is possible to crush kitchen waste and kitchen waste efficiently.
The pulverized kitchen waste and garbage are discharged downward through the slit of the fixed blade 3, the gap between the fixed blade 3 and the rotating disk 5, etc., as described above.
Further, while the disposer is in operation, the water supplied from the water tap Q into the sink S passes through the dumping port 1a, the side water passage M2 and the bottom water passage M3 of the perforated plate member M, and the connection pipe 6 to be pulverized. Water is supplied to the chamber 2 so that the crushed kitchen waste and garbage in the crushing chamber 2 are smoothly discharged to the discharge port 1b.
In addition, in this embodiment, by forming the inner surface of the crushing chamber 2 into a circular arc, adhesion of the rotary blade 4 and the fixed blade 3 to the inner surface of the crushing chamber 2 can be reduced. If a corner portion where the top surface and the side surface intersect is provided, kitchen waste or kitchen garbage adheres to this corner portion, it will adhere to the top surface and the side surface, making it difficult to fall. By forming the inner surface of 2 into an arc shape, there is always only one spot where garbage or garbage adheres, and the cases where garbage or garbage adheres to the inner surface can be reduced.
Further, in this embodiment, in plan view, the inclined surface 2c has an odd-numbered rotationally symmetrical shape centered on the inlet 2a, specifically, a three-rotationally symmetrical shape. There is no inclined surface 2c at the facing position with respect to the center, so that the inside of the crushing chamber 2 can be used widely. If there is an inclined surface 2c at the opposing position, the inner diameter of the crushing chamber 2 becomes narrower by the protruding portion 2b of the inclined surface 2c, which may clog the crushing chamber 2 with a large amount of kitchen waste or garbage. Since there is no inclined surface 2c at the opposing position, it is possible to pulverize even relatively large garbage and garbage.
Through these steps, the pulverized kitchen waste and garbage discharged downward through the slit or the gap between the rotating disk 5 and the fixed blade 3 are discharged from the discharge port 1b to the sewerage through the drain connecting pipe 7. discharged to

During the operation of the disposer, the inside of the grinding chamber 2 is vigorously stirred by the rotating disk 5 inside the grinding chamber 2, so that the pulverized material and water supply, especially the water droplets that have become dirty water in the grinding chamber 2, are discharged into the grinding chamber. 2 and part of it may reach the position of the perforated plate member M.
In this case, in the present embodiment, the side water flow opening M2 and the bottom water flow opening M3 of the perforated plate member M are provided at an angle with respect to the direction from the grinding chamber 2 toward the dumping port 1a, that is, the vertical direction. Garbage, food waste, and sewage pulverized by agitation in the pulverizing chamber 2 flow backward from the pulverizing chamber 2 to the side of the dumping port 1a. is prevented.
In particular, in this embodiment, in plan view, there is no water passage through which the downward direction can be seen, either in the side water passage M2 or in the bottom surface water passage M3. That is, in a plan view, the crushing chamber 2 provided vertically below the dumping port 1a cannot be seen from all the water passages. , through the water passage from below to above.
In addition, in this embodiment, the perforated plate member is arranged such that the bottom water passage M3 provided on a substantially horizontal plane is inclined upward from below toward the hydrant Q, which is the direction in which the user is not present. Since M is arranged at the dumping port 1a, even if garbage, garbage, and sewage pass through the bottom water passage M3, they are guided in a direction away from the user, so that the user gets dirty. There is no

Although the first embodiment of the present invention is as described above, the present invention is not limited to the above embodiments, and can be freely modified within the scope of the invention.
For example, in the above embodiment, the water passage opening of the perforated plate member M has a square shape, but the present invention is not limited to the above embodiment, and may be freely changed to a circular shape or the like as necessary.

In the above embodiment, the backflow prevention structure is a water passage provided in the perforated member M, but the present invention is not limited to the above embodiment. A non-return valve that opens only when water flows from the sink S to the crushing chamber,
As shown in FIG. 6, two plate portions 6a may be arranged on the connecting pipe 6 so as to cover half of the interior of the connecting pipe 6 with different heights. The plate portion 6a is elastic and allows large garbage and food waste to pass downward through elastic deformation.
Further, the water supply from the sink S is supplied into the crushing chamber 2 by flowing down the gap in the vertical direction caused by the height difference.
On the other hand, when pulverized garbage, kitchen waste, sewage, or the like splashes up from the pulverizing chamber 2, it abuts against the lower surface of the plate portion 6a to prevent backflow.
