Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to a kitchen waste processing device, and more specifically,
This relates to a kitchen waste disposal device that can drain kitchen waste and dump it directly into garbage bags, etc. [Prior Art] Many kitchen waste processing apparatuses for crushing and dewatering kitchen waste have already been proposed, such as those disclosed in Japanese Patent Publication No. 59-26345 and Japanese Patent Application Laid-Open No. 62-234555. In other words, in these conventional examples, a crushing blade and a dewatering basket are coaxially provided in a casing connected to the bottom of the kitchen waste inlet of the sink, and the kitchen waste to be thrown away is crushed by the crushing blade, and also After the contained water is dehydrated in a dehydration basket that rotates at high speed, it is stored in the west dust box. [Problem to be solved by the invention] However, the above conventional example has a problem first of all in terms of safety. In other words, since the principle is the same as a mixer, there is a risk of serious injury if you insert your hand into it. To prevent such accidents, double or triple safety measures are required, and an increase in costs is unavoidable. In addition, if gold filG such as spoons and knives are accidentally thrown away, the crushing blades will be chipped, which has the disadvantage of requiring considerable effort and expense to repair. Furthermore, the grinding blade and dehydrator rotate at high speed, which generates a lot of noise. [Means for Solving the Problems] In order to solve the above problems, the present invention includes a cylindrical kitchen waste receiving container provided at the bottom of the sink and having a kitchen waste inlet, and a kitchen waste receiving container provided at a predetermined angle from the bottom of the receiving container. A conveying pipe that rises upward and has a kitchen waste inlet at its lower end and a kitchen waste outlet at its upper end, a screw inserted into the conveying pipe, a swinging means for rotating the screw, and a receiving container. It is equipped with a drain pipe that communicates with the bottom of the container and discharges the waste water in the container, and the drive means for the screw is composed of a reversible rotary motor and is equipped with a reversing switch that temporarily reverses the motor. It is characterized by In this case, it is preferable that a timer is attached to the reversing switch, and the timer outputs a stop signal for the motor after a predetermined period of time has elapsed since the reversing switch was turned on. Furthermore, it is preferable that the rotation torque when the motor rotates in reverse is set larger than the lIJ1 rotation torque when the motor rotates in the forward direction. [Operation] The kitchen waste dumped in the kitchen waste receiving container is taken into the conveying pipe from the kitchen waste intake port by the rotation of the screw, and
The same screw transports the waste toward the kitchen waste outlet.
During this transportation process, the water contained in the kitchen waste is drained, and then the kitchen waste is discharged from the kitchen waste outlet into a garbage bag that has been set in advance at the kitchen waste outlet. In this case, if the screw is locked due to a foreign object such as a clogged kitchen waste or a spoon being caught, the motor can be protected from overload by turning on the reverse switch and reversing the screw. It is also possible to eliminate the begging phenomenon. [Embodiments] Hereinafter, embodiments of the present invention will be explained in detail with reference to the attached figures. As shown in FIG. 1, this kitchen waste processing apparatus includes a cylindrical kitchen waste receiving container 3 having a kitchen waste inlet 2 provided at the bottom of a sink l. A drainer 4 made of metal or synthetic resin is removably stored in the west of this kitchen waste container 3. A conveying pipe 5 is provided at the bottom of the kitchen waste receiving container 3 and rises diagonally upward from the bottom at a predetermined angle. A kitchen waste intake port 5a opening to the bottom of the kitchen waste receiving container 3 is formed at the lower end of the transport pipe 5, and a kitchen waste outlet 5b is provided at the upper end of the transport pipe 5. According to this embodiment, the bottom of the colander 4 fits around the kitchen waste intake port 5a. Referring to the second opening, the kitchen waste container 3
At the bottom of the container, there is a drain pipe 12 for discharging the waste water inside the container.
are communicated. In this case, the drain pipe 12
There is a trap 12 for keeping the liquid level of wastewater stored in the kitchen waste receiving container 3 above the kitchen waste intake port 5a.
A is provided. A screw 6 is rotatably passed through the west side of the conveyor pipe 5. Further, a motor 7 for moving the screw 6 is attached to the lower end side of the conveying pipe 5.
However, the motor 7 may be provided on the upper end side of the conveying pipe 5. In this case, the motor 7 is a reversible motor, and the II'11 rotation torque during reverse rotation is set larger than the IP1 rotation torque during forward rotation. Such rotational torque setting can be performed, for example, by appropriately selecting the main winding and the auxiliary winding. Referring to FIG. 4, which shows an electrical wiring diagram of this device, the motor 7 is equipped with a reverse rotation switch 3l. This reverse rotation switch 3l has a forward rotation side contact a-a and a reverse rotation side contact bb connected to the auxiliary winding side terminal, and when the switching terminal 32 is shown as a solid line in the figure, the rotation is forward, and when it is shown as a chain line, it is reverse rotation. Further, this reversing switch 31 is provided with a timer 34 that turns off the main switch 33 after a predetermined period of time after the switch 31 is turned on.
In this wiring diagram, reference numeral 35 is a timer switch for a timer for setting the operating time, and 36 is a lamp that displays the operating status. A garbage bag 8 made of resin film is attached to the garbage outlet 5b of the conveying pipe 5 by a fitting 9 having a cylindrical shape, for example. In this device, the garbage bag 8 is placed, for example, in a case l3 provided in the front of the sink 1, but in this case, the case l3 can be pivoted by a hinge l4 provided at the lower part of the back side. It is supported. In addition, there is a magnetic plate l5 on the upper back side of the case l3.
A magnet 16, which is connected to the plate 15, and a microswitch 17, which is turned on and off depending on the tilt angle of the case 13, are arranged on the casing side of the device. Although not shown in Fig. 1, case 13 includes
A lid opening/closing detection switch is provided to detect opening/closing of M13a. The simultaneous opening/closing detection switch is indicated by the reference numeral 36 in the wiring diagram of FIG.
When M 13 a is pushed open by the bulge, it is turned off and the motor 7 is stopped. That is, the weight of the garbage bag 8 is detected by the microswitch l7, and
The volume of the garbage bag 8 is detected by the M open/close detection switch 36, and when any of them is turned off,
Motor 7 is stopped. Further, this device is equipped with filter detection means for detecting the presence or absence of a filter 20 that is detachably attached to the kitchen waste input port 2. Referring to FIG. 3, which shows an example, the filter detection means includes a magnet 2l provided on the filter 20 side and a magnetic proximity switch provided on the garbage receiving container 3 side so as to face the magnet 21. 22. When the filter 20 is removed from the garbage inlet 2, the magnetic proximity switch 22 is turned off, for example, and the operation of the motor 7 is stopped. Various switches can be used as this filter detection means, and in addition to the above-mentioned switches, microswitches, optical sensors, ultrasonic sensors, electrostatic sensors, etc. are exemplified. For the arrangement of the magnetic proximity switch 22 on the circuit, please refer to the wiring diagram in FIG. 4. Next, we will explain the operation of this device. First, open M13a of case 13 and remove garbage bag 8.
Attach the lid 13a to the kitchen waste outlet 5b of the conveying pipe 5 using the fixture 9 and close the lid 13a. At this time, since almost no weight is applied to the case l3, the case l3 is sucked and held in its normal position by the magnet l6. Therefore, both the lid opening/closing detection switch 36 and the microswitch l7 are on. This state is maintained until a predetermined weight of kitchen waste accumulates in the garbage bag 8 or until the garbage storage capacity of the garbage bag 8 reaches a predetermined volume. Input kitchen waste from the kitchen waste input port 2, turn on the main switch 33 (start button), and turn the screw 6 1!11 times by the motor 7.
The kitchen waste is transported through the transport pipe 5 by the screw 10, and after being drained along the way, it is discharged from the kitchen waste discharge port 5b to the west of the garbage bag 8. For large kitchen waste, use the kitchen waste intake port 5a.
It is finely cut by the edge of the screw 6 and the blade of the screw 6 and taken into the conveying pipe 5. In this way, the kitchen waste is discharged from the kitchen waste outlet 5b into the garbage bag 8, but when the weight becomes heavy, the case 13 resists the attraction force of the magnet 16 and tilts toward the front side of the device. As a result, the microswitch 17 is turned off, the motor 7 is stopped, and a notification means such as a buzzer (not shown) is used to notify that the garbage bag 8 is full. If the garbage bag 8 expands before its weight and 13a is pushed open, the motor 7 will be stopped in the same way. By the way, if the screw 6 becomes locked due to the insertion of a foreign object such as a spoon or the input of kitchen waste exceeding the limit amount during operation, and the screw 6 becomes locked, the reverse rotation switch 3l can be pressed. As a result, the timer 34 operates at the same time as the motor 7 reverses, and after a predetermined time, the main switch 33 is turned off and the motor 7 is stopped.
Motor 7 and screw 6 are protected from overload.
In this example, the reverse rotation switch 31 is designed to return to the forward rotation side contact a-a when the main switch 33 is turned on again, but even if it is made to return to the normal rotation side contact a-a when the main switch 33 is turned off, good. Further, when the filter 20 is removed during operation, the filter detection means, such as the magnetic proximity switch 22, is turned off, and the motor 7 is stopped in the same manner as described above. When the filter 20 is removed, the motor 7 will not start even if the main switch 33 is pressed. According to this device, the kitchen waste intake port 5a is submerged in the wastewater stored in the kitchen waste receiving container 3, so that the foul odor or abnormal odor generated in the garbage bag 8 does not flow back to the sink 1 side. [Effects of the Invention] As explained above, according to the present invention, since it uses a screw, it is safer and quieter than conventional crushing blades. In addition, since this invention is provided with a reverse switch for the motor that rotates the screw, it is possible to protect the motor and screw from unexpected overload. Furthermore, the effects are remarkable, such as the ability to automatically process kitchen waste without the need for human intervention.
