Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposal device, and more particularly to a garbage disposal device capable of directly dumping garbage discharged from a kitchen into a garbage bag or the like, and more particularly to a sealing mechanism for an garbage container. .

[0002]

2. Description of the Related Art A large number of kitchen waste treatment apparatuses for crushing and dehydrating kitchen waste have already been proposed, for example, Japanese Patent Publication No. 59-26345 and Japanese Patent Publication No. 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 garbage throwing 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.

[0003]

However, since the dust box used in the above-mentioned conventional example is dedicated to the apparatus, has no versatility, and is expensive, it cannot be discarded together with the dust box. Therefore, we proposed to attach a tubular resin film to make the bottom part thermally, and put kitchen waste into this to thermally seal and separate the top part, but two pieces were placed on the hot plate of the sealing part. The encapsulation heater and the encapsulation heater were placed slightly ahead of the encapsulation heater in consideration of the fusion allowance, and the resin film was sandwiched between this and the pad plate. .. However, in the case of this one, there is a drawback that sealing and fusing may be insufficient if there is some inclination or the like.

[0004]

In order to solve the above-mentioned problems, in the present invention, a cylindrical kitchen waste container having a kitchen waste inlet provided at the bottom of a sink, and an upper portion at a predetermined angle from the bottom of the kitchen container. And a bottom end of the receiving container, a conveyor pipe having a kitchen waste inlet at its lower end and a kitchen outlet at its upper end, a screw inserted in the conveyor pipe and a motor for rotating the screw. A drain pipe that is connected to the drain pipe for discharging the waste water in the container, and a discharge pipe is continuously provided to the garbage discharge port of the transfer pipe, and the discharge pipe is disposed so as to surround the discharge pipe. It is composed of a cassette that is folded in a ring shape in the axial direction and accommodates it, and a sealing portion that is located below the cassette and that sandwiches and heat seals the resin film fed from the cassette. In the garbage treatment apparatus, the sealing portion includes two sealing heaters, a hot plate provided with a fusing heater arranged between these sealing plates, and a back plate provided so as to face the hot plate. The hot-melting heater of the hot plate is made to have elasticity and slightly protrudes from the surface of the sealing heater, and the hot-melting heater seals the heating wire through an insulator in a metal tube. It has a feature.

[0005]

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 is conveyed by the screw toward the garbage discharging port. In this transportation process, the water contained in the kitchen waste is drained. After that, the kitchen waste is discharged from a discharge tube connected to the kitchen discharge port into a dust bag formed of a cylindrical resin film and heat sealed, but even if the fusing heater contacts the resin film, it is elastic. Therefore, the two heaters for sealing are brought into contact with the resin film and uniform sealing is performed.

The hot plate 21 includes a fusing heater 21a, a sealing heater 21b, a base material 21c, a heat resistant tape 21d, and a sleeve 21e. The fusing heater 21a seals a nichrome wire in a thin tube made of metal such as stainless steel via magnesium oxide in order to have elasticity. Since the sealing heater 21b needs to be heated and welded to a certain width, the tropical zone is used. Base material 2
Reference numeral 1c is a heat-resistant plate material, and a step for setting the heater in a predetermined position is provided on the heater mounting surface. Two sealing heaters 21b are provided on the upper and lower sides of this surface, and a fusing heater 21a is disposed between them so as to slightly project from the surface of the sealing heater 21b. The heater 21b for sealing also serves as a heat resistant tape 21d for preventing the adhesion of the resin film to the base material 21c.
It is fixed to. The sleeve 21e is made of a metal plate and gives the hot plate 21 a required strength. The backing plate 22 is formed by providing a plate body 22a made of a heat resistant elastic body with a sleeve 22b to give a predetermined strength.

Next, the operation of this device will be described.
First, the dust bag base 17 is attached to the cassette 10, the tubular film is pulled out from the lower gap, and the bottom is formed by the sealing portion 20. This may be fitted with a tubular film whose lower end is sealed. 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 is discharged from the kitchen waste outlet 5b. It is discharged into the garbage bag 18 via When the weighing container 11 has a constant weight, it rotates around the pin 12 against the magnetic force of the magnet 14 and tilts forward. A switch (not shown) detects this movement to operate the seal motor, and the motor rotates the contact plate arm 24 and the heating plate arm 23 in the direction of approaching each other. Eventually, the garbage bag 18 is sandwiched between the heating plate 21 and the backing plate 22,
As shown in FIG. 4, the protruding fusing heater 21a is
The dust bag 18 is brought into contact with the dust bag 18 to be deformed and retracted, and the two sealing heaters are brought into contact with the dust bag 18 to enable uniform sealing.
Since the temperature of the heater is properly set, the sealing is performed first, and then the fusing is performed. As a result, the upper portion of the dust bag 18 is sealed and at the same time the bottom portion of the next dust bag 18 is formed, and the middle portion thereof is melted and separated. When the sealing is completed and the hot plate 21 and the contact plate 22 are separated from each other, the fusing heater 21a returns to the old position due to elasticity.

[0010]

As described above, according to the present invention, since the protruding fusing heater has elasticity, this portion is deformed at the time of sealing and the two sealing heaters are deformed. Since it evenly contacts the dust bag, both sealing and fusing of the dust bag can be performed reliably, and the excellent effect that both dust bags have uniform sealing strength can be obtained.
