BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning method of a disposer that grinds food waste generated in a kitchen or the like with a rotary blade.

The disposer is connected to a drain of a sink such as a kitchen, and receives food waste from the drain at a rotating plate installed at the bottom of the crushing chamber, and rotates the rotating plate with an electric motor to crush it with a striking blade mounted on an upper surface thereof. It is wrapped and cut finely between the fixed blade provided on the inner wall of the bottom of the crushing chamber and the outer circumference of the rotating plate, pulverized, and dropped together with water into the discharge chamber below the rotating plate to discharge the discharge pipe from the discharge pipe connected to the discharge chamber to the sewer pipe.

In such a disposer, it is generally used that the discharge pipe is mounted in the radial direction from the discharge chamber (see Patent Document 1, for example), but pulverized food waste, particularly fibrous food waste, is caught in the discharge port and is not discharged smoothly. It does not, and causes pollution. For this reason, the discharge pipe is provided in the tangential direction to facilitate the discharge (see Patent Documents 2 and 3). In addition, the food waste put into the shredding chamber is contaminated by the centrifugal force of the rotating plate, and the food waste splashes inside the shredding chamber to contaminate the inner wall of the shredding chamber. Since it is discharged through the bottom of the seal, even in the discharge chamber divided by the rotating plate, crushed food waste, oil or detergent residue mixed with water, etc. are attached, and the sludge becomes unhealthy. Rather, it causes a bad smell.

For this reason, it is necessary to wash | clean the inside of a processing apparatus regularly or irregularly. Especially, in small disposers, such as a household, the housewife frequently washes and maintains cleanliness. Such cleaning is generally performed by washing water by pouring water into the crushing chamber and washing it with water flow. However, since the current is not sufficiently washed, a brush or the like is inserted into the crushing chamber from the drain hole of the sink prior to the water washing. Although the debris on the inner wall of the crushing chamber and the rotating plate is removed, not only does it take time, but the discharge chamber located on the lower surface of the rotating plate is divided into the rotating plate, so the brush or the like cannot be inserted to disassemble and clean.

Then, in order to clean the discharge chamber below the rotating plate, a hopper forming the crushing chamber on the upper side of the rotating plate is separated, and the brush member is inserted into the discharge chamber from the hole provided in the rotating plate and mounted on the lower surface of the rotating plate. In addition, it is proposed to clean the discharge chamber by rotating the brush member (see Patent Literature 4), but there is a hassle to remove the hopper.

In addition, a three-way switching valve is installed in the discharge pipe, and when washing, the backwash water is introduced into the processing apparatus in a reverse direction from the food waste disposal from a separate backwash pipe that is installed separately, and the rotating plate is rotated in reverse to the vicinity of the discharge port. In addition, a cleaning device for washing food waste attached to the connection pipe of the discharge port and the switching valve has been proposed (see Patent Document 1).

However, the degree of cleaning only by the flow of water while flowing the washing water into the crushing chamber does not effectively remove the sludge adhered to the inner wall, and it is not only cumbersome to insert the brush from the narrow drain hole of the sink, but also inserts the brush. There is also a risk of accidentally driving the rotating plate in one state, and sufficient cleaning has not been achieved. In addition, 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 of the upper surface of the rotating plate, so there is no big difference in the trouble of separating and disassembling the disposer body from the sink. Housewives can't do it simply.

In addition, in the method of rotating the rotating plate by flowing the washing water in the discharge chamber from the reverse direction while the discharge pipe is blocked, a three-way switching valve or a backwashing pipe for supplying the washing water must be provided separately, which may result in complicated equipment. In addition, since the discharge pipe was clogged during the cleaning, there was a drawback that the dirty water was only stirred by the rotary plate and the cleaning was not performed.

The present invention does not need to be disassembled, and the water is supplied in the same manner as in normal operation, and the water is stored in the discharge chamber below the rotating plate together with the crushing chamber, washed while discharging the wastewater, and washed, and then the crushing chamber and the discharge chamber. It is a technical object of the present invention to provide a method for cleaning a disposer in which a large amount of water stored in the container is rapidly flowed to perform cleaning of the discharge pipe.

In order to solve the above-mentioned problems, a rotary plate having projections made of, for example, a striking blade is provided at the bottom of the crushing chamber located next to the feeding port, and a fixed blade surrounding the rotating plate is provided on the inner wall of the crushing chamber. In the cleaning method of the disposer which crushes garbage and drops the crushed food waste from the periphery of the rotating plate to the discharge chamber below, A trap is formed through the elbow part in the discharge pipe connected to the discharge chamber, In the washing mode, With the rotating plate stopped, water is supplied to the rotating plate in the crushing chamber to block the air passage between the crushing chamber and the discharge chamber at once, thereby trapping the air in the elbow portion of the discharge chamber and the upper part of the trap, and using the air pressure of the trapped air. Water is stored in the crushing chamber and the discharge chamber, and the water stored in the crushing chamber and the discharge chamber is rotated while continuing to supply water to the crushing chamber. By rotating the plate, centrifugal force is applied and stirred in each room, and the entire surface of the room is pressurized by centrifugal force to wash with a rapid flow of water.

In addition, an impeller is installed in the discharge chamber and the discharge pipe is mounted in a tangential direction, and water is supplied to the rotating plate of the crushing chamber to block the air passages of the crushing chamber and the discharge chamber with water to trap the air in the discharge chamber and the upper part of the trap, While rotating on the rotating plate, the rotating plate and the impeller are rotated at low speed (that is, in the opposite direction to the forward direction of crushing food waste), and the pump is reversed to the discharge pipe and drops from the crushing chamber to the drain chamber by the trapped air pressure. Water is stored in the crushing chamber by slowing down the rate of falling of the water, and the water stored in the crushing chamber and the discharge chamber is washed by hitting each chamber inner wall by the centrifugal force of the rotating plate while continuing to supply water.

After washing, the rotating plate is stopped, the impeller is rotated forward to rapidly discharge the water stored in the crushing chamber, and the food waste in the discharge pipe can be flowed under pressure.

Embodiment

In the bottom in the crushing chamber which is located next to the inlet, a rotary plate having protrusions and a fixed blade surrounding the rotary plate are provided, for example, to discharge the crushed food waste from the gap between the rotary plate and the fixed blade below the rotary plate. In the cleaning method of the disposer which drops into a chamber and discharges it, the impeller is installed in the discharge chamber below a rotating plate, the discharge pipe is connected in the tangential direction of a discharge chamber, and a trap is formed through the elbow part through the discharge pipe connected to the discharge chamber, By supplying water on the rotating plate to block the air passage between the crushing chamber and the discharge chamber, it traps the air in the upper part of the trap in the discharge chamber and the discharge pipe, restricts the flow of water to store water in the crushing chamber and the discharge chamber, and continues to supply The water stored in the chamber and the discharge chamber is rapidly stirred by the rotation of the rotating plate, and the centrifugal force is applied to the crushing chamber and the vessel. Thereby cleaning the entire surface in the chamber. After the washing, the impeller is rotated forward to strongly discharge the water in the crushing chamber and the discharge chamber from the discharge port into the discharge pipe, and discharges the trapped food waste collected in the discharge pipe in front of the trap and the trap, and cleans the discharge pipe. .

A plurality of operation modes can be selected along the direction to be attached to the pipe 4. 6 is an inlet of the disposer 1, 7 is a crushing chamber located next to the inlet 6, 8 is a rotating plate provided at the bottom of the crushing chamber 7, 9 is an example of a projection mounted on the upper surface of the rotating plate 8 10 is a fixed blade fixed to the bottom of the crushing chamber 7, 11 is a discharge chamber installed below the rotating plate 8, 12 is mounted on the lower surface of the rotating plate (8) One impeller, 13 is a discharge port, 14 is a discharge pipe, and in this embodiment, the discharge port 13 and the discharge pipe 14 are provided in the tangential direction of the discharge chamber 11 as shown in FIG. The discharge pipe 14 is connected downward through the elbow portion 15, and a trap 16 is formed. 17 is an electric motor for driving the rotating plate 8.

As shown in FIG. 4, an upper surface of the mounting tube 4 includes an index 20 of an operation mode, and the notch grooves 21 are respectively opened to the upper surface inside the upper end of the inlet 6 in accordance with the position of the index 20. ), The sensor 22 (FIG. 1) is provided in the outer side. As shown in (a) and (b) of FIG. 5, the cover 5 is provided with a through hole 23 and a coupling protrusion 24 coupled to the cutout groove 21 on an outer circumferential surface thereof. The magnet 25 is built in the position 24.

Then, the notch groove 21 is opened as a groove covering the upper surface at a predetermined angle, for example, at a position shifted by 20 °, and the engaging projection 24 of the cover 5 is inserted and rotated by 20 ° to rotate the magnet ( 25 may be adapted to the position of the sensor 22.

In addition, although the discharge pipe 14 is attached in the tangential direction in this embodiment, it can also be mounted in the radial direction. However, in order to effectively effect the pump action by the impeller 12 in the discharge chamber 11, it is preferable to mount in the tangential direction. In addition, when storing water in the sink 2, a cover without a water hole may be used.

When processing food waste with the disposer 1 (in the case of a batch processing), food waste is thrown in from the inlet 6 onto the rotary plate 8 of the crushing chamber 7, and an appropriate amount of food waste is discharged from the drain 3. When the cover 5 is attached to the index of the "run" while the coupling protrusion 24 is supplied with water, the magnet 25 sends a signal to a control device (not shown) by the sensor 22 at the "run" position. By transmitting, the electric motor 17 is started in "operation mode." When the water is supplied after the cover 5 is inserted, it is started through a separately installed start switch or by a timer for some time so as not to start immediately even when the cover 5 is inserted. You can start it.

6, the example of the control characteristic of "operation mode" is shown. In the initial stage of startup, the forward rotation (which may be reverse rotation) for a short time, for example, two seconds at a low speed n1, is repeated several times (three times in the drawing) to detect whether metal foreign matter or the like is mixed. In the case of mixing, foreign matters are scattered by the centrifugal force of the rotating plate 8 and hit the inner wall of the crushing chamber 7 so that an impact sound is generated. Therefore, the operation is stopped to remove the foreign matters and then restarted. If no foreign matter is detected, the rotary plate 8 is operated at low speed in the direction of the arrow A in Fig. 3 for continuous time t1, and then the speed is increased at the rated speed n2. The crushed food waste is discharged together with water from the outlet 13 of the discharge chamber 11 in the direction indicated by the arrow B, passes through the elbow portion 15, and is not shown through the trap 16 by the discharge pipe 14. Discharged to sewer pipes. When the food waste is crushed and the load current of the electric motor 17 becomes small, the electric motor 17 is stopped.

Next, the "cleaning mode" will be described.

7 shows an example of control characteristics. When the cover 5 is fitted in accordance with the index of "cleaning", first, the operation is repeated several times for a short time at a low speed n1, and it is detected whether foreign matter is mixed. If foreign matters are mixed, they are scattered by the centrifugal force of the rotating plate 8 and generate an impact sound. Therefore, the operation is stopped to take out the foreign matters. When it is confirmed that foreign matter is not mixed, the rotary plate 8 is stopped and water is supplied from the drain port 3 onto the rotary plate 8.

The water supplied from the drain port 3 is at least water that has fallen on the rotating plate 8 and spreads about evenly around the rotating plate 8, or is scattered through a cover or rubber plate (not shown) or the like. Even when this diffuses and flows around the circumferential wall of the crushing chamber 7, it also flows almost on the entire surface, and the entire surface of the gap G (Fig. 3) on the rotating plate 8 and the fixed blade 10 around the rotating plate 8. Is enough to cover.

Water is supplied to the crushing chamber 7 in a state where the rotating plate 8 is stopped, and water flows into the entire surface of the gap G between the rotating plate 8 and the fixed blade 10 at a time to open the air passage of the discharge chamber 11. If they are all blocked at the same time, the air that has entered the elbow portion 15 above the water trap W in the discharge chamber 11 and the trap 16 of the discharge pipe 14 is trapped.

If the water supply continues while the air passage is blocked, and the space of the trapped air R decreases with water falling from the crushing chamber 7 to the discharge chamber 11 through the gap G, the air R is shown in FIG. 2. As described above, the water surface W of the trap 16 is lowered by being pressed toward the elbow portion 15, but at the same time, the passage of water falling into the trap 16 through the elbow portion 15 is compressed and the amount of water discharged to the trap 16 is limited. As a result, the amount of discharged water passing through the elbow portion 15 becomes smaller than the amount supplied to the crushing chamber 7. In addition, since the air pressure in the discharge chamber 11 is increased, the amount of water falling from the crush chamber 7 to the discharge chamber 11 through the gap G is also slightly reduced. Therefore, water can be stored in the crushing chamber 7 according to the difference between the supply quantity supplied to the crushing chamber 7 and the limited discharge quantity.

While the amount of water stored in the crushing chamber 7 increases, the water falling into the discharge chamber 11 increases due to the weight of the stored water, so that the air pressure increases, whereby the air R further presses the water surface W of the trap 16 and lowers it. If the water level W is lowered by the height H of the trap, the trapped air is discharged from the trap 16, the air pressure decreases, the limit of the water passing through the elbow portion 15 decreases, the amount of drainage increases, 7) the weight of the water stored in the water and the increase of the drainage increases the force of the water falling from the crushing chamber 7 to the discharge chamber 11, the water is filled in the discharge chamber 11 instead of air, the crushing chamber 7 and discharge When the water in the chamber 11 is combined, it is strongly discharged by the weight of the stored water.

The speed and amount of water stored depends on the capacity of the disposer 1, the quantity of supply, the size of the gap G between the rotary plate 8 and the fixed blade 10, the amount of air trapped, the height H of the water sealed in the trap 16, and the like. However, according to the experimental results of the present invention, in a small disposer having a domestic crushing chamber capacity of about 1 liter, the water passage of 8 liters per minute, if the air passage around the rotary plate 8 is blocked at once, about 15 from the water supply It was confirmed that the crushing chamber 7 became almost full in about a second, and the water surface W of the trap 16 descended to the curved portion in about 28 seconds, and air was released.

In the above experiment, since water is supplied in a state where the rotating plate 8 is stopped, the structure in which the discharge port 13 of the discharge chamber 11 is tangential and the action of the impeller 12 need not be considered. It installs in a radial direction and operates similarly, even if the impeller 12 is not provided.

Therefore, the electric motor 17 is rated when the time t2 (about 15 seconds in the above experiment) has elapsed in the state where the air passage is blocked by water supply and the crushing chamber 7 is almost full according to the above-described experiment result. Start at rotation speed n2. In addition, the water level sensor may be installed in the crushing chamber 7 to start the electric motor 17 when the required quantity is reached. The rotation speed does not necessarily have to be the rated rotation speed, and the water can be stirred and the centrifugal force can be applied. What is necessary is just enough rotation speed. When the electric motor 17 is started, the rotating plate 8 and the impeller 12 are rotated, and the water stored in the crushing chamber 7 and the discharge chamber 11 is rapidly stirred by centrifugal force, and each room is subjected to strong water pressure. Clean.

In this way, since the water in the crushing chamber 7 is agitated when the required amount is agitated, the water can be effectively washed. Even if the amount of the crushing chamber 7 decreases due to drainage, the remaining water and the water to be continuously supplied are centrifugal force. Pressurized on the inner wall to continue cleaning.

When water is discharged from the crushing chamber 7 to the discharge port 13 during the washing, the water surface W of the trap 16 is pushed down to the height H, and when the air escapes and the restriction of the discharge amount is eliminated, the amount of water discharged during the washing increases. Thus, a large amount of water is rapidly discharged through the trap 16 at that weight. Therefore, the discharge chamber 11 becomes negative pressure so that the water in the crushing chamber 7 is ejected into the discharge chamber 11 to clean the gap between the rotary plate 8 and the fixed blade 10 and to the trap 16. The drain pipe can be drained in large quantities to prevent blockage in the discharge pipe.

In the 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, the discharge chamber 11 is discharged from the gap G together with the water from the crushing chamber 7. As the air enters the furnace, the water can be trapped by the water supply and stored again, and the washing can be repeated or rinsed.

In addition, water can be stored in the crushing chamber 7 and the number of rotations of the impeller 12 is increased so that the water flows rapidly into the discharge pipe 14 by the pumping action, thereby preventing the inside of the discharge pipe 14 from being blocked.

In the case where the washing continues after the crushing of the food waste or the washing is repeatedly performed, the repeated operation at a low speed for detecting the foreign matter can be omitted.

Next, the example of the control characteristic shown in FIG. 8 is demonstrated.

The impeller 12 is provided in the discharge chamber 11, and the rotating plate 8 and the impeller 12 are stopped similarly to the embodiment of FIG. 7 by using a disposer in which the discharge port 13 is formed in a tangential direction. In this state, water is supplied to the crushing chamber 7, the air passage is blocked to trap air, and water is stored in the crushing chamber 7 and the discharge chamber 11.

When water in the crushing chamber 7 becomes approximately a predetermined amount at time t2, the electric motor 17, the rotating plate 8, and the impeller 12 are rotated back at a low speed n3. Therefore, the centrifugal force is applied to the water in the crushing chamber 7 by the rotating plate 8 to be rotated and washed while being pressed against the inner wall of the crushing chamber 7, while the centrifugal force is also applied to the water in the discharge chamber 11 by the impeller 12. While the room is cleaned and drained, the pump of the impeller 12 acts in the reverse direction, thus slowing the falling rate of the water falling from the crushing chamber 7 to the discharge chamber 11 to maintain the water in the crushing chamber 7 and continuing. With the water supplied, washing | cleaning in the crushing chamber 7 is continued with the rotating plate 8. Therefore, the washing | cleaning water quantity in the crushing chamber 7 can be hold | maintained so that the rotation speed n3 of the reverse direction may become the same quantity of water drained from the drain opening 13 and the water continuously supplied to the crushing chamber 7, Can be adjusted freely.

When the cleaning is finished at time t3, the rotating plate 8 and the impeller 12 are stopped, and the washing water in the crushing chamber 7 and the discharge chamber 11 is discharged. Even if water is continuously supplied to the crushing chamber 7, since the discharge chamber 11 becomes negative pressure due to the discharge of the washing water, from somewhere around the swivel plate 8 together with the water falling from the crushing chamber 7 to the discharge chamber 11. Since air enters the discharge chamber 11, when the negative pressure is released and water supply in the stopped state continues, water is stored in the crushing chamber 7 by the same operation as described above. By rotating the impeller 12 forward, the water stored in the shredding chamber 7 is rapidly discharged by the normal pumping action, and the food waste remaining in the discharge pipe 14 flows through the rinse and the cleaning of the discharge pipe 14 is performed. I can do it.

Then, 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, and the dirty washing water in the crushing chamber 7 and the discharge chamber 11 is discharged by pumping action, and the rotating plate 8 ), The next water may be stored.

FIG. 10 is a characteristic curve showing an example of washing after crushing food waste, and similarly to FIG. 6, a short time operation of low speed n1 is repeated several times to detect the incorporation of foreign matter, and it is confirmed that there is no incorporation of foreign matter. After continuously operating at n1 for a predetermined time, the grinding process is performed by increasing the speed at the rated rotation speed n2. When the grinding process is completed, the rotating plate 8 and the impeller 12 are switched to reverse rotation of the low speed n3. When the impeller 12 is rotated in reverse, the pump acts in the reverse direction to slow down the falling rate of water falling from the crushing chamber 7 to the discharge chamber 11 so that the water is stored in the crushing chamber 7 and the rotating plate 8 The centrifugal force is applied to perform the washing, and the discharge chamber 11 is also washed with water in the discharge chamber 11.

When the rotating plate 8 and the impeller 12 are stopped by washing for a predetermined time, sewage used for washing is discharged, and then the water supplied is stored in the crushing chamber 7 as in the embodiment of FIG. The discharge pipe 14 is cleaned by rotating the 12 in a forward direction and rapidly discharging the discharge pipe 14.

In the present invention, since the air passages of the crushing chamber and the discharge chamber are blocked by supplying water to the crushing chamber, the disposer is inclined so that the rotating plate is inclined, or a water supply port is provided on the side of the crushing chamber to drain water from one side to the other. In the case of the supplying disposer, the amount of trapped air decreases as the blockage of the air passage is partially delayed, and the discharge quantity is not sufficiently limited due to the decrease in the air pressure, so that the time for storing water becomes long or the water is stored. It may not be. Therefore, it is also necessary to correct the rotating plate to be horizontal at the time of mounting the disposer or to increase the amount of water supplied until it is blocked.

11 shows an example of water supply from the crushing chamber side of the disposer, and the same reference numerals are given to the same parts as in FIG. 1.

Water supply to the crushing chamber 7 is performed from the water supply port 28 provided on the side wall of the crushing chamber 7 via the water supply pipe 27 by the solenoid valve 26, and the water supply port 28 is conventionally known. Instead of just opening the side in the transverse direction from the side, as shown in the center portion of the rotating plate 8, water dropped on the rotating plate 8 from the water supply port 28 during the cleaning is the entire surface of the rotating plate 8. Air flow in the air passages in the surrounding discharge chamber 11 to be uniformly blocked at once.

In the case of water supply from the side surface of the disposer, it is preferable to install the water supply port 28 at a high position approaching the drain port 3 as much as possible to diffuse the water falling on the rotating plate 8 in the direction of the center part. Do.

In addition, when the sink 29 is provided in the sink 2, when the overflow pipe 30 is normally connected to the discharge pipe above the trap, the inside of the discharge chamber 11 when the air is trapped Since the air escapes through the overflow pipe 30 to the water outlet 29, the overflow pipe 30 is connected to the grinding chamber 7, or as shown, the two-diameter joint 31. The excess water is discharged into the crushing chamber 7 by being connected to the water supply pipe 27 through the pipe.

FIG. 12 shows a disposer 1a according to another embodiment, an annular water supply pipe 32 is provided around the upper part in the crushing chamber 7, and a plurality of water supply holes 33 are provided on 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 shown by the arrow, and the water is equally supplied to the gap G around the fixed blade 10 and the rotating plate 8 along the inner wall. Therefore, the air passage can be effectively blocked.

13A and 13B show another embodiment of the rotating plate 8. At the time of washing, it is preferable to simultaneously flow water supplied on the rotating plate 8 into all the gaps G as much as possible, and feed water to the center of the rotating plate 8 in order to close the gaps G at once. Therefore, the edge 34 is provided on the outer periphery of the rotating plate 8 provided with the striking blade 9 fixed to the upper surface to equalize the height. By providing such an edge 34, even if there is a possibility that water is leaned toward the other side of the rotating plate 8, for example, to the left, and the air passage on the right side may be blocked late, the edge 34 is present, so that the water dropped to be offset Since water stored on the entire surface on the rotating plate 8 and the edge 34 flows into the surrounding air passage at the same time, the air passages in all directions are blocked at once, so that it can be effectively blocked.

And instead of the edge 34, as shown in FIG. 14, you may incline the upper surface of the rotating plate 8 to a plate shape so that the outer periphery may become high.

In addition, a cover without a water hole is provided in the drain hole 3 of the sink 2 to store water, and the water is poured into the crushing chamber 7 while removing the cover while supplying water, thereby crushing the chamber 7 and the discharge chamber 11. You can also block the air passages.

The present invention, the water supply to the upper surface of the rotating plate in the stopped state, block the air passage of the crushing chamber and the discharge chamber, traps the air between the discharge chamber and the water surface of the trap, and stores the water in the crushing chamber using the air It is not necessary to dismantle the device, it does not dirty the hands by simple operation, and it discharges the cleaned sequential water in order by effectively rotating and stirring the rotating plate with the rotating plate while supplying enough stored water. It can be washed.

In addition, by installing an impeller in the discharge chamber below the rotating plate, connecting the discharge pipe in the tangential direction of the discharge chamber, and rotating the rotating plate and the impeller while continuing to supply water on the rotating plate, slowing down the dropping rate of water from the discharge chamber to the crushing chamber. The washing time can be adjusted by keeping water inside.

In addition, by stopping the rotating plate and supplying water to the crushing chamber to trap the air in the discharge chamber, a large amount of water can be stored in the crushing chamber, and this water can be drastically flowed into the discharge pipe by the forward rotation of the impeller. Food waste or garbage collected in the discharge pipe can be discharged by pressure to clean the inside of the discharge pipe, thereby preventing the discharge pipe from being blocked.
