Regarding

[0002]

2. Description of the Related Art There have already been proposed many kitchen waste processing apparatuses for crushing and dehydrating kitchen waste, for example, Japanese Patent Publication No. 59-263.
45 and JP-A-62-234555. That is, in these conventional examples, a crushing blade and a dehydration basket are coaxially provided in a casing connected to the lower part of the kitchen throw-in port of the sink, and the discarded garbage is crushed by the crushing blade, and The contained water is dewatered in a dewatering basket that rotates at high speed, and then collected in a dust box. However, the crushing blade is accompanied by danger, high-speed rotation produces noise, and the dust box is expensive, so the applicant of the present invention invented a new device using a low-speed rotation screw and a heat-sealed dust bag. Japanese Patent Laid-Open No. 2-303699 has been proposed. As shown in FIG. 2, these are detachably housed with a draining basket 4 made of metal or synthetic resin in a cylindrical kitchen waste container 3 having a kitchen waste inlet 2 provided at the bottom of a sink 1. .. At the bottom of the garbage receiving container 3, there is provided a conveying pipe 5 which rises obliquely upward from the same portion at a predetermined angle. At the lower end of the carrier pipe 5,
The kitchen waste container 3 is provided with a kitchen waste intake port 5a opening at the bottom thereof, and an upper end of the carrier pipe 5 is provided with a kitchen waste discharge port 5b. Further, a screw 6 is rotatably inserted in the carrier pipe 5, and a motor 7 for driving the screw 6 to rotate is attached to the lower end side of the carrier pipe 5. A garbage discharge tube 8 is connected to the garbage discharge port 5b of the transport pipe 5, and a cassette 10 is disposed surrounding the kitchen discharge tube 8 and containing a resin film to be formed into a garbage bag. A sealer 20 for heat-sealing the resin film is provided below the. Below the sealer 20, a weighing container 11 for accommodating the dust bag is arranged with a gap between the housing bottom plate and the bottom plate, and the lower part of the rear face is supported by pins 12 standing from the bottom plate and the magnetic plate is formed on the upper part of the rear face. 13 and is held by a magnet 14 with the plate 13 as a counterpart. On the other hand, a drain pipe 9 for discharging the drainage in the waste container 3 is connected to the bottom of the waste container 3, and the liquid level of the waste water stored in the waste container 3 is connected to the drain pipe 9 through the waste inlet 5a. A trap, not shown, is provided for holding above.

Since the conventional example is constructed in this way,
The garbage thrown in from the garbage throwing port 2 is conveyed in the conveying pipe 5 by the screw 6, is drained in the middle thereof, and then passes through the garbage discharging port 5b and the garbage discharging cylinder 8 to remove the garbage bag 18
When the weighing container 11 is discharged to the inside and the weight becomes constant, the magnet 1
Rotate around the pin 12 against the magnetic force of 4 and tilt forward,
A switch (not shown) detects this movement and the motor 7
To stop. However, the magnetic force of the magnet used in the above-mentioned conventional example has many variations, and therefore a large amount of dust accumulates a large amount of dust in the bag and cannot be heat-sealed, while a small one has a sufficient storage space. It had the drawback of being heat-sealed and uneconomical. Further, there is a drawback that the weight is not detected when the weight of the dust does not lower to the bottom of the weighing container due to some reason. Further, if the apparatus is operated with the weighing container 11 taken out for cleaning or the like, the motor 7 does not stop, and there is a drawback that dust overflows.

A cassette that is folded in a ring shape in the axial direction and accommodates it, and a cassette located below the cassette that comes out of the cassette and comes into contact with a resin film that is formed in a dust bag and heat-sealed. In a kitchen waste disposal apparatus comprising a sealing part and a weighing container located below the sealing part for accommodating a dust bag and detecting the volume, the weighing container is a bag for detecting the dust bag inside the peripheral wall. It is equipped with a detection plate, a bag detection switch operated by the detection plate, and a photo sensor above that detects an appropriate amount of dust.When the sensor continuously detects dust for a certain period of time, the motor is stopped. It is characterized by becoming.

[0006]

According to the above construction, the garbage thrown into the garbage receiving container is taken into the conveying pipe from the garbage intake by the screw and conveyed to the garbage discharging port by the screw. In this transportation process, the water contained in the kitchen waste is drained. After that, the garbage is discharged from a discharge tube connected to the garbage discharge port into a garbage bag formed of a cylindrical resin film. When the amount of dust increases and the dust bag is pulled out of the cassette to reach the bottom of the weighing container, and the dust accumulates and the bag inflates and presses the bag detection plate, the bag detection switch driven by this is turned on. When the photo sensor is shielded by dust and the amount of light is reduced, the motor control circuit starts a timer and continues detection for a certain period of time thereafter. When dust is continuously confirmed during that time, the motor is stopped and sealing is started.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. 2 which is a sectional view of the front part of the apparatus, omitting the same parts as those of the prior art. As shown in the drawing, a cassette 10 is provided so as to surround the garbage discharge tube 8, and a sealer 20 is provided below the cassette 10.
The heating plate 22 held by the heating plate arm 24 and the heating plate 21 held by the heating plate arm 23 face each other. In the cassette 10, a dust bag mother body 17 in which a tubular film made of a thermoplastic resin such as polyethylene is axially folded into a donut shape is housed, and the film fed out from the gap at the lower end becomes a dust bag 18. The lower end reaches the weighing container 11, and the dust 19 is stored inside. The weighing container 11 has a bag detection plate 30 for detecting the dust bag 18 inside a housing front and rear partition plate 25 forming a peripheral wall.
And a bag detection switch 32 operated by the detection plate 30.
Is equipped with. The bag detection plate 30 has a U-shape that is open rearward, and the upper portion thereof is pivotally supported by a pin 31 on a mounting plate provided on the front and rear partition plate 25 of the housing to swing into a through hole formed in the front and rear partition plate 25 of the housing. It hangs freely. Bag detection switch 3
Reference numeral 2 is a micro switch attached to the back surface of the front and rear partition plate 25, and the actuator 33 is brought into contact with the rear edge of the bag detection plate 30 and protrudes inward of the weighing container 11. And
The door 15 and the front and rear partition plates 2 for easy understanding in the figure
5, preferably above the left and right walls of the main body 1, is provided with a photosensor 34 including a light emitter 35 and a light receiver 36 for detecting an appropriate amount of dust. FIG. 3 is a block diagram showing a main part of control relating to dust detection. The bag detection switch 32 and the photo sensor 34 are connected to the input side of the motor control circuit 40 to which the timer 41 is connected, and the motor 7 is connected to the output side. Has been done.

Next, the operation of this device will be described.
First, in FIG. 2, the dust bag mother body 17 is attached to the cassette 10, the tubular film is pulled out from the lower gap, and the bottom is formed by the sealer 20. For this, a tubular film whose lower end is sealed beforehand may be attached. When the kitchen waste is thrown in through the kitchen waste input port 2 and the screw 6 is rotated by the motor 7, the kitchen waste is transported in the transport pipe 5 by the screw 6, drained in the middle, and then the kitchen waste outlet 5b.
Is discharged into the garbage bag 18 through the garbage discharge cylinder 8, and the garbage 19 is accumulated in the garbage bag 18 and reaches the bottom of the weighing container 11 by its weight. When the dust 19 accumulates in the dust bag 18 to a certain amount, the inflated dust bag 18 presses the bag detection plate 30 and swings it outward, so that the actuator 33 is pushed and the bag detection switch 32 operates. .. When the dust bag 18 is detected, the photo sensor 34 starts detecting the dust 19. In the present embodiment, the photo sensor 34 has been operated for a long time, but it may start when the dust bag 18 is detected and may start detection at the same time. In FIG. 3, when the output of the bag detection switch 32 enters the motor control circuit 40, the photo sensor 34 starts detecting the dust 19. Then, when dust is detected, the motor control circuit 40 starts the timer 41. When the photo sensor 34 continuously detects the dust 19 until the timer setting time ends, the motor control circuit 40 stops the rotation of the motor 7 and then starts the heat sealing. FIG. 4 is a flowchart showing a process of detecting the volume of the dust 19. When the bag detection switch 32 and the photo sensor 34 are turned on, the timer 41 operates for a certain period of time, and the photo sensor 34 continues the detection during this period. If the photo sensor 34 is turned on until the set time expires, that is, if the presence of dust 19 is confirmed, it is considered that the volume set value has been reached, and the motor control circuit 40 stops the rotation of the motor 7. If not confirmed, it is a temporary dust. Return to the beginning assuming that there was. This is because when a large amount of dust passes, the photo sensor 34
Detects the dust 19, the detection is continued once for a certain period of time, and the rotation of the motor 7 is stopped assuming that the predetermined volume value is reached when the dust 19 is detected even when the set time has expired. Returning to FIG. 2, when the amount becomes appropriate, the motor 7 is stopped, the screw 6 is stopped, and then the hot plate 21 and the contact plate 22 are brought into contact with the dust bag 18 to energize the hot plate 21 and the heater 21b. The upper part of the dust bag 18 is sealed with and at the same time the bottom of the next dust bag 18 is formed, and the heater 21a melts and separates.

[0009]

As described above, according to the present invention, it is confirmed by the bag detection plate and the bag detection switch that the bag is at the bottom of the weighing container, and the photosensor seals the bag when it reaches a certain volume. Therefore, it is possible to prevent a large amount of dust from being accumulated in the bag to be heat-sealed, or to be heat-sealed even if there is a sufficient storage space, and to always treat an appropriate amount of dust. be able to. Since members related to weighing are arranged so as not to be taken out at the time of cleaning, dust does not overflow during operation.
