Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a soot processing apparatus, and more particularly, to a soot processing apparatus that is attached to a lower part of a kitchen sink and crushes soot such as garbage.
[0002]
[Prior art]
The culm treatment device is attached to the lower part of the drain of the sink of the kitchen, pulverizes the raw garbage input through the input / output port on the sink side, and discharges it together with the waste water. There are two known types of soot processing devices: a continuous processing type that continuously grinds garbage, and a batch processing type that grinds raw garbage in a state where a necessary amount of treatment is accumulated.
[0003]
In the case of a continuous processing type slag processing device, the motor and the pulverizing mechanism are rotated in advance, and the garbage is intermittently charged into the processing tank and continuously pulverized and discharged based on the rotation of the motor. To do. While the completion of the pulverization process is judged by eyes and sounds, the motor is stopped, while in the case of a batch processing type slag processing device, the necessary amount of raw garbage is put into the processing tank in advance and the opening is closed with a lid. In this state, the garbage is thrown into the batch process at once by rotating the motor. Also in this case, the completion of the pulverization was judged by eyes and sound, and the motor was stopped.
[0004]
[Problems to be solved by the invention]
As described above, the continuous slag processing device intermittently throws in garbage, so that the motor rotates without closing the opening with a lid, whereas in the batch slag processing device, the opening The motor does not rotate unless it is closed with a lid, and each has a dedicated safety device and control device, both of which are fixed as a continuous type or a batch type. For this reason, there is no room for selecting which method the user can use.
[0005]
Further, when foreign matter is mixed in the garbage, if the pulverizing mechanism bites the foreign matter, the motor overheats and causes a failure.
[0006]
SUMMARY OF THE INVENTION Therefore, a main object of the present invention is to provide a soot processing device with an automatic function that can be controlled by switching between continuous and batch pulverization processing and that can immediately stop the motor even when foreign matter is caught. That is.
[0007]
[Means for Solving the Problems]
The present invention relates to a slag processor having a slag and water inlet, a pulverizing mechanism driven by a motor, and a smashed water and water outlet. A switching means for switching between a continuous processing mode for processing and a batch processing mode for pulverizing with the required amount of soot stored in the inlet, a load detecting means for detecting a change in the load amount of the motor, and drive control The drive control means includes a continuous operation timer for continuously driving the motor, and a certain period of time until the soot is introduced into the inlet according to being switched to the continuous processing mode The motor is driven, the driving time of the motor is variably extended depending on the number of inputs and the amount of garbage, and the driving of the motor is stopped when it is detected that the load has been reduced.
[0008]
On the other hand, when it is detected that the inlet has been blocked and the batch processing mode has been switched, the motor is driven after the required amount of soot is added, and the motor drive time is set according to the amount of garbage. The drive of the motor is stopped when it is detected that the load has been variably extended and the load has become lighter, and based on the detection output of the load detection means, it is determined that the crushing mechanism has been caught in the foreign matter. And stopping the motor.
[0009]
Therefore, according to the present invention, the user can select between the continuous processing mode and the batch processing mode by the switching means and performing the continuous pulverization processing by the pulverization mechanism or the batch pulverization processing, and the motor is stopped even if foreign matter enters. Therefore, the occurrence of failure is prevented in advance.
[0010]
Preferably, the drive control means varies the drive time of the motor in accordance with the amount of the load, and when it is detected that the load has become lighter, the drive control means stops the motor after a certain time in order to crush the remaining dust. And a residual operation timer.
[0011]
More preferably, it includes a charging preparation timer for driving the motor for a fixed time until the bag is inserted into the charging slot when the continuous processing mode is selected.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a longitudinal sectional view of a soot treating apparatus according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view of a crushing mechanism attached to the container 1 of FIG.

The turntable 7 is provided with hammers 71 and 72 that swing outward in two places, and the grind ring 6 has a fixed blade 61 formed on the inner peripheral surface side thereof. The turntable 7 is rotationally driven by the motor 2 shown in FIG. 1, and when garbage is put on the turntable 7 from the upper part of the hopper 5, the garbage is pressed against the inner surface side of the grind ring 6 by centrifugal force. The hammers 71 and 72 of the turntable 7 are crushed by pressing the garbage against the fixed blade 61 of the grind ring 6.
[0014]
Further, the housing 4 is provided with a drain port 10, and raw garbage crushed in the hopper 5 is discharged from the discharge port 10 together with water injected from above.
[0015]
As shown in FIG. 1, a sink flange support ring 11 for attaching the soot processing device to the sink is provided on the upper portion of the hopper 5. The opening of the sink flange support ring 11 serves as a garbage inlet, and a splash guard 12 is housed in the lower part of the sink flange support ring 11. The splash guard 12 prevents the scattered material from pulverizing from jumping out from the inlet and limits the size of the inlet so that the fingertip does not touch the movable part when the garbage is thrown in. ing. On the splash guard 12, an opening into which a sink flange cap 13 as a lid member is inserted is closed.
[0016]
1 is used as a continuous type, the opening of the sink flange support ring 11 is not closed by the sink flange cap 13, and only when the batch type is used, the sink flange support ring by the sink flange cap 13 is used. 11 openings are closed. A magnet 14 is embedded in the handle portion of the sink flange cap 13, and a cap switch 15 including a reed switch is embedded in the outer peripheral portion of the sink flange support ring 11. When the cap switch 15 is used as a batch type when the sink flange cap 13 is inserted into the sink flange support ring 11 and the opening is closed, the contact is closed by the magnetic force of the magnet 14 of the sink flange cap 13. Detect that the opening is closed.
[0017]
A control board 20 is attached to the lower wall surface of the container 1 in which the motor 2 is housed. The control board 20 is connected to the wiring from the cap switch 15 and the switch box 30. Yes.
[0018]
FIG. 3 is a block diagram showing an electrical system of the soot processing apparatus in one embodiment of the present invention. In FIG. 3, a noise filter 21, a motor protection device 22, an automatic operation switch circuit 23, and a rectifier 24 are provided on the control board 20 shown in FIG. 1. The noise filter 21 removes noise mixed in the AC 100V, and the motor protection device 22 protects the motor 2 from damage caused by heating. The automatic operation switch circuit 23 performs motor drive control as a continuous type or a batch type. The rectifier 24 rectifies 100 V AC and supplies a DC voltage to the motor 2.
[0019]
A cap switch 15 embedded in the sink flange support ring 11 and a switch box 30 are connected to the automatic operation switch circuit 23. The switch box 30 is provided with an operation button 31, a stop button 32, an indicator 33, and a lid switch 34. The operation button 31 commands the rotation of the motor 2, and the stop button 32 gives a command to urgently stop the rotation of the motor 2. The indicator 33 displays whether it is during pulverization, is stopped, or is in an abnormal state. The lid switch 34 switches between the batch type and the continuous type, and is turned off when operating in the batch type and turned on when operating in the continuous type.
[0020]
FIG. 4 is a block diagram showing the automatic operation switch circuit shown in FIG. In FIG. 4, a DC power supply 231 steps down AC100V to rectify and supplies a DC voltage to the circuit described below. The flip-flop 232 stores operation and stop, and an operation command signal is input from the operation button 31 via the set-side OR circuit, and a stop command signal is input from the stop button 32 via the reset-side OR circuit. . A POCLR signal for forcibly resetting the flip-flop 232 when the power is turned on is input to the flip-flop 232 via the reset side OR circuit.
[0021]
The output of the flip-flop 232 is given to the indicator 33. This indicator 33 also serves as three types of displays. It glows strongly during operation, weakly shines during normal stop, and turns off when there is an abnormality. Even if the user cannot confirm the operation sound, the crushing is completed and the machine status is indicated. It is made visible. The output of the flip-flop 232 is also input to the preparation timer 235. When the operation button 31 is pressed, the charging preparation timer 235 continues to operate for about 25 seconds. During this period, the garbage is intermittently put in the continuous type, or the garbage already put in the batch type is crushed. Then, the making preparation timer 35 gives a reset signal to the reset side OA circuit of the flip-flop 232 after 25 seconds, for example.
[0022]
The AC switch 241 is an electronic relay that turns on / off AC 100V, and is configured by, for example, a triac. When the flip-flop 232 is set, the AC 100V is turned on. As described above, the cap switch 15 is embedded in the sink flange support ring 11, and the flange cap 13 with the magnets 14 inserted at both ends of the handle portion is set at the lower circumferential position and set in the middle portion of the dust inlet. The contact is closed. The lid switch 31 is a switch for switching between batch processing and continuous processing, and is turned off when operating in a continuous mode, and turned on when operating in a batch mode.
[0023]
The continuous operation limiting timer 234 is provided for protection to continuously limit long-time operation when the power is turned on by the AC switch 241, and before the motor protection device 22 shown in FIG. 3 operates. Abnormal operation is detected in advance, and the motor 2 is stopped to prevent a failure from occurring. For example, when a large amount of raw garbage is continuously input or garbage that is very difficult to pulverize is input, the operation is stopped for 3 consecutive minutes for safety.
[0024]
The load sensor 237 detects the presence / absence of garbage and biting according to the load of the motor 2, and detects the end of the pulverization process when the load of the motor 2 becomes light. When the load sensor 237 detects a reduction in the load on the motor 2, the continuous operation timer 236 performs a residual operation for a certain period of time in order to clean the remaining garbage and the grinding chamber and the drainage route. A stop signal is given to the reset-side OA circuit of the flip-flop 232.
[0025]
The automatic protection circuit 238 protects the motor 2 and the control circuit by giving a stop signal to the reset side OA circuit of the flip-flop 232 when it is detected that biting has occurred based on the output of the load sensor 37. Plan.
[0026]
Next, a specific operation of one embodiment of the present invention will be described.
First, when the pulverization process is performed continuously, the indicator 33 is lit weakly when the wiring and piping connection are completed and the AC 100V is energized. When the lid switch 15 is turned off, the splash guard 12 is set to a normal state, and the operation button 31 is pressed, the indicator 33 shines strongly and the motor 2 rotates. At the same time, a suitable amount (about 10 liters) of water from the faucet is poured.
[0027]
When the operation button 31 is pressed, the flip-flop 232 is set, and the input preparation timer 235 starts measuring the time of 25 seconds by the output. During this time, the user continuously puts the first garbage into the hopper 5. During this time, if no garbage is thrown in, the operation stops in 25 seconds.
[0028]
On the other hand, when the flip-flop 232 is set, the AC switch 241 operates, and the continuous operation limiting timer 234 starts measuring time. When the garbage is sequentially added, the time measured by the continuous operation timer 236 is extended due to an increase in the motor load, the last garbage is completely charged, and when the load sensor 237 detects that the load on the motor 2 is lightened, For example, the continuous operation timer 236 measures a time of 10 seconds and starts the residual operation. When the continuous operation timer 236 finishes counting the time of 10 seconds, the driving of the motor 2 is stopped, and the indicator 33 returns to the initial state and shines weakly.
[0029]
If the pulverization processing time continuously exceeds, for example, 3 minutes, the continuous operation limiting timer 234 operates and the flip-flop 232 is reset. Further, when the stop button 32 is pressed during operation, the flip-flop 232 is reset, and the motor 2 can be immediately stopped even during the crushing operation.
[0030]
In addition, foreign matter may be mistakenly mixed into the hopper 5 during operation, and the rotation of the motor 2 may suddenly stop. In this case, the motor protection device 22 operates after about 6 seconds, and the automatic operation switch circuit 23 is connected to the automatic operation switch circuit 23. As a result, the power supply is stopped, and as a result, the indicator 33 is turned off, so that an abnormality can be notified.
[0031]
Moreover, since the foreign substance mixed in can easily remove the rubber splash guard 12 set downward from the garbage input port by hand, it can be easily removed after the user turns off the power and confirms safety.
[0032]
Next, a batch type operation will be described. In this case, the lid switch 15 is turned on, the necessary amount of garbage is put into the hopper 5, the sink flange cap 13 is set in the direction designated by the sink flange support ring 11, and the water flows from the faucet. When the button 31 is pressed, the flip-flop 232 is set, the indicator 33 shines strongly, and the motor 2 is driven. While the motor 2 is being driven, the load sensor 237 detects that a load is applied to the motor 2, and the continuous operation time timer 236 starts measuring the time, and the continuous operation is continued during that time. When the pulverization process is completed, the continuous operation timer 236 starts to measure the remaining operation time for cleaning, for example, about 10 seconds, and then the flip-flop 232 is reset to stop the operation.
[0033]
If the sink flange cap 13 is removed from the sink flange support ring 11 while the crushing operation is continued, the cap switch 15 detects this and turns off the AC switch 241, so the continuous operation limiting timer 234 and the flip-flop 232 are turned off. The drive of the motor 2 is stopped with the set.
[0034]
However, if the sink flange cap 13 is set on the sink flange support ring 11 again during the continuous operation time, the operation is resumed as it is. However, when the indicator 33 is weakly lit, the operation is not resumed unless the operation button 31 is operated again to set the flip-flop 232.
[0035]
Further, by using the sink flange cap 13 that can be switched from fully closed to semi-closed, water supply and pulverization with the accumulated water in the sink can be performed.
[0036]
Further, even if foreign matter is mistakenly mixed during operation and the rotation of the motor suddenly stops, the automatic protection circuit 238 resets the flip-flop 232 based on the detection output of the load sensor 237 so that the motor 2 is burned out. To prevent unforeseen failures. Also in this case, the foreign matter mixed in can be easily removed after the rubber splash guard 12 is removed by hand and the user turns off the power and confirms safety.
[0037]
As described above, according to the embodiment of the present invention, the user can arbitrarily select the continuous type and the batch type and perform the pulverization process.
[0038]
The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
[0039]
【The invention's effect】
As described above, according to the present invention, if the soot inlet is not sealed and switched to the continuous processing mode, the motor is driven for a certain period of time until the soot is introduced into the inlet, and the load It is detected that the operation time is extended and the load is lightened by the size of the motor, and the driving of the motor is stopped after the residual operation. If the inlet is sealed and switched to the batch processing mode, the motor is driven after the soot is thrown to crush the soot so that the load is reduced while continuing operation as in the continuous processing mode. The drive of the motor is stopped in response to the fact that it has been detected. Thereby, the user can arbitrarily switch between the continuous type and the batch type.
[0040]
Furthermore, it is possible to determine that foreign matter has been mixed according to the load applied to the motor, and stop the motor to prevent the occurrence of a failure.
