Description

The present invention relates to a disposer cleaning method for crushing cocoons generated in a kitchen or the like with a rotary blade.

The disposer is connected to a sink outlet in a kitchen or the like, and receives the dredging introduced from the outlet with a rotating plate provided at the bottom of the crushing chamber, and rotates the rotating plate with an electric motor and attaches it to the upper surface. And crushing by finely shearing between the fixed blade provided on the inner wall of the bottom of the crushing chamber surrounding the rotating plate and the outer periphery of the rotating plate, and dropping into the discharge chamber below the rotating plate together with water. From the discharge pipe connected to the sewage pipe.

In such a disposer, a discharge pipe having a discharge pipe attached in a radial direction from the discharge chamber is generally used (see, for example, Patent Document 1), and pulverized soot, in particular, fiber soot is entangled in a discharge port or the like. Smooth discharge, causing dirt. For this reason, a discharge pipe is provided in the tangential direction to facilitate discharge. (Patent Document 2, Patent Document 3)
In addition, since the soot put into the crushing chamber is subjected to centrifugal force by the rotating plate, not only does the spatter scatter in the crushing chamber and contaminate the crushing chamber wall, but it is also crushed between the periphery of the rotating plate and the fixed blade. Since the soot drops into the discharge chamber and flows through the bottom of the discharge chamber, it is discharged into the discharge chamber partitioned by a rotating plate. In addition, it is not preferable in terms of hygiene due to the sludge condition, but it also causes a bad odor.

For this reason, it is necessary to clean the inside of the processing apparatus regularly or irregularly. Especially, a small-sized disposer for home use is frequently cleaned by a housewife to keep it clean. For this cleaning, water cleaning is generally performed by pouring water into the crushing chamber and rinsing with the water flow. However, since sufficient cleaning cannot be performed with only the water flow, the sink drain hole of the sink leads into the crushing chamber prior to water cleaning. Inserting a brush, etc., and removing dirt on the crushing chamber wall and the rotating plate to wash it with water, it is not only troublesome, but the discharge chamber on the lower surface of the rotating plate is partitioned by the rotating plate, so brushes etc. Could not be inserted and had to be disassembled and cleaned.
To clean the discharge chamber below the rotating plate, remove the hopper that forms the crushing chamber above the rotating plate, insert the brush member into the discharge chamber from the hole provided in the rotating plate, attach it to the lower surface of the rotating plate, and rotate Although the thing which cleans the discharge chamber by rotating a brush member with a board is proposed (refer patent document 4), there exists a troublesome thing which has to remove a hopper.
In addition, a three-way selector valve is provided in the discharge pipe. During cleaning, the drain pipe is closed and backwash water is introduced from the separately provided backwash pipe into the treatment device in the direction opposite to that during dredging. There has been proposed a cleaning device that reversely rotates a plate to wash away soot that adheres to the vicinity of the discharge port or to the connection pipe between the discharge port and the switching valve (see Patent Document 1).

However, it is not possible to effectively remove the sludge adhering to the inner wall by washing with only the water flow while pouring the washing water into the crushing chamber. Insert a brush etc. from the narrow drain outlet of the sink. However, not only was the operation troublesome, but there was also a risk of accidentally driving the rotating plate with the brush inserted, and sufficient cleaning was not possible. Moreover, in order to insert the brush member into the discharge chamber from the hole provided in the rotating plate, it is necessary to remove the hopper and expose the hole on the upper surface of the rotating plate. Neither was it easy for housewives to do.
Also, in the method of rotating the rotating plate by feeding wash water into the discharge chamber from the reverse direction with the discharge pipe closed, a three-way switching valve and a backwash pipe for supplying the wash water must be provided separately. Not only is the equipment complicated, but the discharge pipe is closed during cleaning, so cleaning is performed simply by stirring the dirty water with a rotating plate during cleaning. There was an unfortunate drawback.
The present invention supplies water in the same manner as in normal operation without the need for disassembly, collects water in the discharge chamber on the lower surface of the rotating plate together with the crushing chamber, and cleans and discharges dirty water. The present invention provides a cleaning method in which the discharge pipe is also cleaned by rapidly flowing a large amount of water stored in the crushing chamber and the discharge chamber.

For this reason, a rotating plate with a protrusion is provided at the bottom of the crushing chamber following the inlet, and the crushing crust is crushed with a fixed blade surrounding the rotating plate on the crushing chamber wall. In the disposer that drops into the discharge chamber and discharges it, a trap is provided on the discharge pipe connected to the discharge chamber via an elbow-shaped part, and in the cleaning mode, the rotating plate is stopped and placed on the rotating plate in the crushing chamber. Water is supplied to block the air passage between the crushing chamber and the discharge chamber at once, thereby confining the air that was in the elbow-shaped part above the discharge chamber and the trap, and using the air pressure of the trapped air, Water is stored in the discharge chamber, and the water stored in the crushing chamber and the discharge chamber is stirred by applying centrifugal force in each chamber by rotating the rotating plate while continuing to supply water to the crushing chamber. Push and sudden It is as in washing with a water stream.
In addition, an impeller is provided in the discharge chamber, and a discharge pipe is attached in the tangential direction, while rotating the rotating plate and the impeller at low speed while supplying water on the rotating plate, and draining from the crushing chamber by reverse pumping action and confined air pressure. The water falling in the chamber is delayed to accumulate water in the crushing chamber, and the water stored in the crushing chamber and the discharge chamber is washed against each indoor wall by the centrifugal force of the rotating plate while continuing to supply water.
In addition, after washing | cleaning, the rotating plate is stopped, the impeller is rotated forward, the water accumulated in the crushing chamber is rapidly discharged, and the stagnation in the discharge pipe is washed away.

As described above, the present invention supplies water to the upper surface of the rotating plate in a state where the operation is stopped, blocks the air passage between the crushing chamber and the discharge chamber, and confines the air between the discharge chamber and the water surface of the trap. Water is accumulated in the crushing chamber using air, and the water that has been sufficiently accumulated is rapidly stirred with a rotating plate and washed with water flow by centrifugal force while continuing to supply water, so there is no need to disassemble the device at all. A simple operation does not contaminate the hands at all, and an efficient cleaning effect can be obtained while sequentially discharging the washed sewage.
In addition, an impeller is provided in the discharge chamber below the rotating plate, a discharge pipe is connected in the tangential direction of the discharging chamber, and water is supplied from the discharge chamber by rotating the rotating plate and the impeller in reverse while continuing water supply on the rotating plate. The water can be held in the crushing chamber by delaying the falling of the water, and the cleaning time can be adjusted.
In addition, by stopping the rotating plate and supplying water to the crushing chamber and confining the air in the discharge chamber, a large amount of water can be stored in the crushing chamber, and this water can be rapidly flowed into the discharge pipe by the forward rotation of the impeller. It is possible to clean the inside of the discharge pipe by washing away the scum and dust remaining in the discharge pipe leading to the sewer, and to obtain an effect of eliminating clogging.

At the bottom of the crushing chamber following the input port, there is a rotating plate with protrusions and a fixed blade surrounding the rotating plate, and the crushed soot is discharged from the gap between the rotating plate and the fixed blade into the discharge chamber below the rotating plate. In the disposer that drops and discharges, the impeller is attached to the discharge chamber below the rotating plate, the discharge pipe is connected in the tangential direction of the discharge chamber, and the trap is connected to the discharge pipe connected to the discharge chamber via the elbow-shaped part. By supplying water on the plate and closing the air passage between the crushing chamber and the discharge chamber, the air above the trap in the discharge chamber and the discharge pipe is confined, and the amount of water outflow is limited to the crushing chamber and the discharge chamber. The water is stored, and the water accumulated in the crushing chamber and the discharge chamber is rapidly stirred by the rotation of the rotating plate while the water supply is continued, and centrifugal force is applied to wash the entire surface of the crushing chamber and the discharge chamber. After cleaning, the impeller is rotated forward so that the water in the crushing chamber and the discharge chamber is pumped out from the discharge port into the discharge pipe, and the trap and the trapped soot remaining in the previous discharge pipe from the trap Etc. to wash out the discharge pipe.

Hereinafter, the drawings will be described.

Is a disposer, 2 is a sink, 3 is a drainage port of the sink, 4 is a mounting tube for attaching the disposer 1 to the drainage port 3, and 5 is a lid attached to the drainage port 3, and is attached to the mounting tube 4 as shown in FIG. A plurality of operation modes can be selected depending on the direction. 6 is a slot for the disposer 1, 7 is a crushing chamber following the slot, 8 is a rotating plate provided at the bottom of the crushing chamber 7, 9 is a striking blade attached to the upper surface of the rotating plate 8, and 10 is a rotating plate 8 The fixed blade 11 is fixed to the bottom of the crushing chamber, 11 is a discharge chamber provided below the rotary plate 8, 12 is an impeller attached to the lower surface of the rotary plate 8, 13 is a discharge port, and 14 is a discharge pipe. In the embodiment, as shown in FIG. 3, the discharge port 13 and the discharge pipe 14 are provided in the tangential direction of the discharge chamber 11. The discharge pipe 14 is connected downward through an elbow-like portion 15 and is provided with a trap 16. Reference numeral 17 denotes an electric motor that drives the rotating plate 8.

As shown in FIG. 4, the upper surface of the mounting tube 4 is provided with an operation mode index 20, and a notch groove 21 opened on the upper surface inside the upper end portion of the charging port 6 in accordance with the position of the index, and a sensor on the outer side. 22 (FIG. 1) is provided. As shown in FIG. 5, the lid 5 has a water passage hole 23 and an engagement protrusion 24 fitted in the notch groove 21 on the outer peripheral surface, and a magnet 25 is embedded at the position of the engagement protrusion 24.
The notch groove 21 is opened to a position shifted by a certain angle, for example, 20 degrees as a groove covering the upper surface, and the engaging projection 24 of the lid 5 is inserted and rotated 20 degrees to move the magnet 25 of the sensor 22. It can be adapted to the position.
In this embodiment, the discharge pipe 14 is attached in the tangential direction, but it can be attached in the radial direction. However, in order to effectively perform the pump action by the impeller 12 in the discharge chamber 11, it is desirable to attach in the tangential direction. Further, when water is stored in the sink 2, a blind cover without a water passage hole may be used.

When processing the soot with the disposer (in the case of batch processing), the soot is put on the rotating plate 8 of the crushing chamber 7 from the input port 6 and an appropriate amount of water is supplied from the drain port 3 while engaging projections. When the lid 5 is mounted in accordance with the “driving” index 24, the sensor 22 at the “driving” position sends a signal to a control device (not shown) by the magnet 25 to start the electric motor 17 in the “driving mode”. When water is supplied after the lid 5 is inserted, it is activated via a separate activation switch so that it does not start immediately even if the lid 5 is inserted, or it is activated after a short time with a timer. Just do it.

FIG. 6 shows an example of the control characteristics of the “operation mode”. At the beginning of activation, a normal rotation (or reverse rotation) of 2 seconds, for example, at a low speed n ₁ is repeated several times (three times in the figure) to detect whether or not metal foreign matters are mixed. In the case of contamination, the foreign matter is bounced off by the centrifugal force of the rotating plate 8 and hits the inner wall of the crushing chamber 7 to generate an impact sound. Therefore, the operation is stopped and the foreign matter is removed and then restarted. If the foreign matter is detected, after a continuous operation for a certain time t ₁ the rotating plate 8 in the direction of arrow A in FIG. 3 at low speed, it is speed increasing a rated rotational speed n _2. The crushed soot is discharged together with water from the discharge port 13 of the discharge chamber 11 as shown by an arrow B, and is discharged through an elbow-like portion 15 through a trap 16 by a discharge pipe 14 to a sewer pipe (not shown). When the soot is crushed and the load current of the motor becomes small, the motor 17 is stopped.

Next, the “cleaning mode” will be described.
FIG. 7 shows an example of control characteristics. When the lid 5 is mounted in accordance with the “cleaning” index, _first , a short time operation is repeated several times at a low speed n ₁ to detect whether foreign matter is contained. If there is a foreign object, it will be blown off by the centrifugal force of the rotating plate and will make an impact sound, so the operation is stopped and the foreign object is removed. When it is confirmed that no foreign matter is contained, the rotating plate 8 is stopped and water is supplied from the drain port 3 onto the rotating plate 8.
The amount of water supplied from the drain port 3 is that at least the water that has fallen on the rotating plate 8 spreads almost evenly around the rotating plate 8, or the water is diffused by a lid or a rubber plate scattering prevention device (not shown). Even when it flows through the peripheral wall of the crushing chamber 7, it flows on almost the entire peripheral surface so as to cover the entire surface of the gap G (FIG. 3) between the rotating plate 8 and the fixed blade 10 around the rotating plate 8.

When water is supplied into the crushing chamber 7 in a state where the rotating plate 8 is stopped, water flows into the entire surface of the gap G between the rotating plate 8 and the fixed blade 10 and closes all the air passages to the discharge chamber almost simultaneously. Air that has entered the elbow-like portion 15 above the discharge chamber 11 and the water surface W of the trap 16 of the discharge pipe 14 is trapped.
Water supply continues with the air passage closed, and when the space of the trapped air R is reduced by the water falling from the crushing chamber 7 through the gap G to the discharge chamber 11, the air pressure rises. 2, the water surface W of the trap 16 is pushed down by being pressed against the elbow-shaped portion 15, but at the same time, the passage of water that passes through the elbow-shaped portion 15 and falls into the trap 16 is compressed to limit the amount of water discharged to the trap 16. In addition, the amount of water discharged through the elbow-shaped portion 15 is smaller than the amount of water supplied to the crushing chamber 7. Further, since the air pressure in the discharge chamber 11 is increased, the water falling from the crushing chamber 7 through the gap G to the discharge chamber 11 is also somewhat reduced. For this reason, water can be stored in the crushing chamber 7 according to the difference between the amount of water supplied to the crushing chamber 7 and the limited amount of discharged water.

As the amount of water accumulated in the crushing chamber 7 increases, the amount of water falling into the discharge chamber 11 increases due to the weight of the accumulated water, the air pressure increases accordingly, and the air R further pushes down the water surface W of the trap 16, When the trap height H is lowered, the trapped air is discharged from the trap, the air pressure decreases, the amount of water passing through the elbow-shaped portion 15 is reduced, the amount of drainage is increased, and the air is accumulated in the crushing chamber 7. The momentum of water falling from the crushing chamber 7 to the discharge chamber 11 is increased by the increase in the weight of the water and the amount of drainage, the water is filled in the discharge chamber 11 instead of air, and the water in the crushing chamber 7 and the discharge chamber 11 is integrated. When it becomes, it drains vigorously with the weight of the accumulated water.

The speed and amount of water accumulation depends on the capacity of the disposer, the amount of water supplied, the size of the gap G between the rotating plate and the fixed blade, the amount of trapped air, the height H of the sealed water in the trap, etc. As a result, with a small-sized disposer with a crushing chamber capacity of about 1 liter for home use, when the air passage around the rotating plate is almost closed at a stretch with water supply of 8 liters per minute, about 15 seconds from the water supply. Thus, it was confirmed that the crushing chamber was almost full, and the water surface W of the trap 16 was lowered to the bent portion in about 28 seconds to leak air.
In this experiment, since water is supplied in a state where the rotating plate 8 is stopped, there is no need to consider the structure of the discharge chamber 11 in the tangential direction and the action of the impeller 12, the discharge port 13 is provided in the radial direction, Even if the impeller 12 is not provided, the same operation can be obtained.

Therefore, according to the above experimental result, when the air passage is blocked by the water supply and the time t ₂ (about 15 seconds in the above experiment) has passed and the crushing chamber 7 is almost full, the motor 17 is set to the rated rotational speed n. Start with ₂ . It should be noted that a water level sensor is provided in the crushing chamber 7 so that the electric motor 17 can be started when the required amount of water is reached. Any rotational speed may be given. When the electric motor 17 is started, the rotating plate 8 and the impeller 12 are rotated, and the water accumulated in the crushing chamber 7 and the discharge chamber 11 is agitated rapidly by centrifugal force, and each chamber is washed with a strong water pressure.
In this way, since stirring is performed when the amount of water in the crushing chamber 7 reaches a required amount, washing can be performed effectively, and even if the amount of water in the crushing chamber 7 is reduced by drainage, the remaining water continues. The water supplied in this way is pressed against the inner wall by centrifugal force, and cleaning can be continued.
If water is discharged from the crushing chamber 7 to the discharge port 13 during cleaning, the water surface W of the trap 16 is pushed down to a height H, air leaks, and there is no limit on the amount of drainage. Increasingly, a large amount of water is rapidly drained through the trap 16 by its weight. For this reason, the discharge chamber 11 becomes negative pressure, and the water in the crushing chamber 7 is jetted into the discharge chamber 11 to clean the gap between the rotary plate 8 and the fixed blade 10, and from the trap 16 to the previous discharge pipe. A large amount of drainage is generated and the clogging in the drain pipe is washed away.

For stirring and washing, the rotating plate 8 may be rotated for about 3 to 8 seconds. When the water in the discharge chamber 11 is discharged and becomes negative pressure, air enters the discharge chamber 11 through the gap G together with the water from the crushing chamber 7. Therefore, air can be confined by water supply and water can be stored again, and washing can be repeated or rinsed.
In addition, clogging in the discharge pipe can be eliminated by accumulating water in the crushing chamber 7, increasing the rotation speed of the impeller, and rapidly flowing it through the discharge pipe by a pump action.
In addition, when it wash | cleans continuously after grind | pulverizing a soot, or when performing washing | cleaning repeatedly, the low speed repeated operation for detecting a foreign material can be abbreviate | omitted.

Next, an example of the control characteristics shown in FIG. 8 will be described.
Water is supplied to the crushing chamber 7 in a state where the rotating plate 8 and the impeller 12 are stopped as in the embodiment of FIG. 7 using a disposer in which the impeller 12 is provided in the discharge chamber 11 and the discharge port 13 is provided in the tangential direction. Then, the air passage is closed to confine the air, and water is accumulated in the crushing chamber 7 and the discharge chamber 11.
When the water of the crushing chamber 7 is substantially a predetermined amount at time t _2, the rotary plate 8 and the impeller 12 is reversely rotated at a low speed n ₃ by an electric motor 17. For this reason, the rotating plate 8 applies centrifugal force to the water in the crushing chamber 7 to rotate and wash it against the wall of the crushing chamber, and the water in the discharge chamber 11 is also centrifuged by the impeller 12 to wash the room. Although the water is drained, the pumping action of the impeller 12 works in the opposite direction, so that the water falling from the crushing chamber 7 to the discharge chamber 11 is delayed to hold the water in the crushing chamber 7, and subsequently supplied water. At the same time, the crushing chamber is continuously cleaned with the rotating plate 8. Therefore, if the rotational speed n ₃ in the reverse direction is set so that the amount of water drained from the drain port 13 and the amount of water continuously supplied to the crushing chamber are approximately the same, the amount of washing water in the crushing chamber 7 is maintained. The cleaning time can be adjusted freely.

When cleaning is completed at time t ₃ , the rotating plate 8 and the impeller 12 are stopped, and the cleaning water in the crushing chamber 7 and the discharge chamber 11 is discharged. Even if the water supply to the crushing chamber is continued, the discharge chamber 11 becomes negative pressure due to the discharge of the washing water, so air enters the discharge chamber 11 from somewhere around the rotating plate together with the water falling from the crushing chamber 7 to the discharge chamber 11. When the negative pressure is eliminated and the water supply in the stopped state continues, water accumulates in the crushing chamber 7 by the same action as described above. The impeller 12 is rotated forward so that the water accumulated in the crushing chamber 7 is quickly discharged by a normal pumping action, and the drain pipe is washed by rinsing the scum and the like remaining in the discharge pipe. it can.

As shown in the characteristic curve shown in FIG. 9, when the cleaning is completed, the impeller 12 is rotated forward at a low speed so that the dirty cleaning water in the crushing chamber 7 and the discharge chamber 11 is discharged by a pump action, and the rotating plate 8 may be stopped and the next sump may be performed.

FIG. 10 is a characteristic curve showing an example in which washing is performed subsequent to the pulverization process of the soot. Similar to FIG. 6, a short time operation at a low speed n ₁ is repeated several times to detect the inclusion of foreign matters. After confirming that there is no contamination, the vehicle is continuously operated at a low speed n ₁ for a certain period of time, and then the speed is increased to the rated rotational speed n ₂ to perform pulverization. And the grinding process is completed switch the rotating plate 8 and the impeller 12 in the reverse rotation of the low speed n _3. When the impeller 12 rotates in the reverse direction, the pumping action in the reverse direction works to delay the fall of the water falling from the crushing chamber 7 to the discharge chamber 11 and the water accumulates in the crushing chamber. The discharge chamber 11 is also washed with water in the discharge chamber.
When the rotating plate 8 and the impeller 12 are stopped after cleaning for a predetermined time, the cleaned sewage is discharged, and the water supplied subsequently is accumulated in the crushing chamber 7 as in the embodiment of FIG. Rotate forward to quickly discharge to the discharge pipe and clean the discharge pipe.

In the present invention, the air passage between the crushing chamber and the discharge chamber is closed by supplying water to the crushing chamber, so that the disposer is inclined and the rotating plate is inclined, or a water supply port is provided on the side of the crushing chamber. In the case of a disposer or the like that supplies water from one side to the other side, the amount of air trapped is partially delayed due to blockage of the air passage, and the amount of discharged water is sufficiently limited by reducing the air pressure. This is not done, and there is a possibility that the time for storing the water may become longer or the water may not be stored. For this reason, it is also necessary to correct the disposer attachment so that the rotating plate is horizontal or to increase the amount of water supplied until the disposer is closed.

FIG. 11 shows an example in which water is supplied from the side surface of the crushing chamber of the disposer, and the same reference numerals are given to the same parts as in FIG.
Water supplied to the crushing chamber 7 is supplied from a water supply port 28 provided on the side wall of the crushing chamber 7 through a water supply pipe 27 by a solenoid valve 26, and the water supply port 28 is simply opened laterally from the side as in the prior art. Instead, it opens toward the center of the rotating plate 8, and water that has dropped onto the rotating plate 8 from the water supply port 28 during cleaning spreads over the entire surface of the rotating plate 8 and is an air passage with the surrounding discharge chamber 11. It flows evenly and closes at once.
In addition, when water is supplied from the side surface of the disposer, it is desirable to provide the water supply port at a high position as close as possible to the drainage port 3 so as to diffuse the water falling on the rotating plate toward the center.
Further, when the overflow port 29 is provided in the sink 2, if the overflow pipe 30 is connected to the discharge pipe above the trap as usual, the air in the discharge chamber 11 passes through the overflow pipe 30 when trapping the air. In order to leak into the overflow port 29, the overflow pipe 30 is connected to the crushing chamber 7, or is connected to the water supply pipe 27 via a different diameter joint 31 as shown in the figure, and the overflow water is discharged to the crushing chamber 7.

FIG. 12 shows another embodiment of the disposer, in which an annular water supply pipe 32 is provided around the upper part in the crushing chamber 7, and a large number of water supply holes 33 are provided toward the side wall. In this embodiment, the water from the water supply hole 33 is supplied toward the inner wall of the crushing chamber 7 as indicated by the arrow, and is uniformly supplied to the gap G between the fixed blade 10 and the periphery of the rotating plate 8 along the inner wall. Therefore, the air passage can be effectively blocked.

FIG. 13 shows another embodiment of the rotating plate 8. When cleaning is performed, it is desirable that water supplied onto the rotating plate 8 is poured into the gap G around the entire circumference as much as possible, and water is supplied to the center of the rotating plate 8 in order to close the gap G at a stretch. For this reason, the edge 34 is provided in the outer periphery of the rotating plate 8 which provided the striking blade 9 fixed to the upper surface, and is made equally high. By providing such an edge 34, even if there is a possibility that water is supplied to one side of the rotating plate 8, for example, to the left side, and the blockage of the right air passage may be delayed, the rim 34 is provided and the water drops. The accumulated water accumulates on the entire surface of the rotating plate 8, and the water beyond the edge 34 overflows into the surrounding air passages at the same time. Therefore, the air passages around the entire circumference can be closed at once, and the blockage can be effectively performed.
Instead of the edge 34, as shown in FIG. 14, the upper surface of the rotating plate 8 may be inclined in a dish shape so that the outer periphery becomes higher.

Further, a blind cover is put on the drain port 3 of the sink 2 to collect water, and the blind cover is removed while pouring water and poured into the crushing chamber 7 to block the air passage between the crushing chamber 7 and the discharge chamber 11. You can also.
