Abstract

PURPOSE:To improve safety by forming a notched groove on the periphery of a spiral blade exposed in the garbage intake of a screw and providing a claw inserted in the notched groove on the conveyor pipe side. CONSTITUTION:Garbage is charged from a garbage feed port 2, and the screw 6 is rotated by a motor 7. Consequently, the garbage is conveyed in the conveyor pipe 5 by the screw 6, drained in its course and discharged into a refuse bag 8 from a garbage discharge port 5b. The garbage is introduced into the conveyor pipe 5 by the notched groove 10 formed on the periphery of the spiral blade 6a. Large garbage is cut and introduced into the conveyor pipe 5. The peelings, etc., are detained by the notched groove 10 and removed by the claw 11. When the weight of the bag 8 is increased, the case 13 is inclined to this side of the device against the attracting force of a magnet 16, and a microswitch 17 is turned off. The garbage is easily treated in this way.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a kitchen waste processing device, and more specifically,
The present invention relates to a kitchen waste disposal device that can directly dump kitchen waste from a kitchen into a garbage bag or the like while draining it.

[Conventional technology]

Many kitchen waste processing apparatuses for crushing and dewatering kitchen waste have already been proposed, such as Japanese Patent Publication No. 59-26345 and Japanese Patent Application Laid-Open No. 62-234555.

That is, in these conventional examples, a crushing blade and a dewatering basket are coaxially provided in a casing connected to the lower part 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 high-speed rotating dehydrator, it is collected in the dust box.

[Problem to be solved by the invention]

However, the above conventional example has a problem first of all in terms of safety. That is, since the principle is the same as that of a mixer, there is a risk of serious injury if you make a single move. To prevent such accidents, double or triple safety measures are required, and an increase in costs is inevitable. Furthermore, if a spoon or knife is accidentally thrown away, the crushing blade may be chipped and the tableware may also be damaged. Furthermore, both the crushing blade and the dewatering basket rotate at high speed, which generates a lot of noise.

[Means to solve the problem]

In order to solve the problem described above, in the present invention, a cylindrical kitchen waste receptacle having a kitchen waste inlet provided at the bottom of the sink is connected to a container, and the kitchen waste receptacle rises upward from the bottom of the container at a predetermined angle, A conveying pipe having a kitchen waste inlet at the lower end and a kitchen waste outlet at the upper end, a screw inserted into the conveying pipe, an opening means for rotating the screw, and a kitchen waste receiver at the bottom of the container. It is equipped with a drainage pipe that communicates with the container and discharges the waste water in the container, and has a structure in which a cutout groove is formed on the outer periphery of the spiral blade exposed at the kitchen waste intake port of the screw. In this case, it is preferable to provide a claw that can fit into the notch groove without interfering with the conveying pipe side.

[For production]

The kitchen waste dumped into the container is taken into the conveying pipe through the kitchen waste intake port by the rotation of the screw.
The same screw transports the waste toward the kitchen waste outlet.

In this case, since the notch groove is provided on the outer periphery of the helical blade exposed at the kitchen waste intake port of the screw, the kitchen waste is efficiently taken in, and large kitchen waste is crushed into small pieces and taken in. Moreover, even if a string or a leather-like object is caught in the notch groove, it will be scraped out by the nail. During the conveyance process by the screw, the water contained in the kitchen waste is drained. Thereafter, the kitchen waste is discharged from the kitchen waste discharge port into a garbage bag that has been set in advance at the kitchen waste discharge port.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 1, this kitchen waste processing apparatus includes a cylindrical kitchen waste receptacle 3 having a kitchen waste inlet 2 provided at the bottom of a sink l. In this kitchen waste receptacle, a draining basket 4 made of metal or synthetic resin is removably housed in a container 3.

The kitchen waste receptacle is provided with a conveying pipe 5 at the bottom of the container 3 that rises diagonally upward from the bottom at a predetermined angle. A kitchen waste intake port 5a that opens at the bottom of the container 3 is formed at the end of the WI transfer pipe 5, and a kitchen waste discharge port 5b is provided at the upper end of the transfer pipe 5. .

A screw 6 is rotatably inserted into the conveying pipe 5. Further, a motor 7 for rotationally driving 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.

As shown in FIGS. 3 and 4, a cutout groove 10 is provided on the outer periphery of the helical blade 6a exposed within the garbage intake port 5a of the screw 6.

In connection with this, a claw 11 is provided on the kitchen waste intake port 5a side of the Wi feed pipe 5 to fit into the notch groove 10 thereof without interference. In this embodiment, only one notch groove IO is provided, but the number thereof can be arbitrarily selected. For example, the notch groove IO may be provided in a gear shape over the entire circumference of each pitch of the spiral 11g6a. The end surfaces 10a, 10a in the notch groove 10 may be parallel to the thickness direction of the spiral blade 6a, or may have an obtuse or acute angle with respect to the thickness direction, but considering the relationship with the claw 11, the rotation of the screw 6 An angle that is nearly parallel to the direction is preferred.

A draining basket 4 is placed around the kitchen waste intake port 5a of the conveying pipe 5.
In this case, as shown in Fig. 2, the lower ends of the screws 6 are fitted on the kitchen waste winding side (in this example, the screws 6 rotate counterclockwise at the same time, so the left end side in Fig. 2). The left wall 4a of the colander 4 disposed in the drainer basket 4 has a shape that rises almost perpendicularly from the kitchen waste winding end A thereof. Preferably, the opening is in the tangential direction at the garbage winding end A of the screw 6, but it may open slightly outward from that. On the other hand, the right wall 4b of the colander 4 is formed so that its lower part bulges outward.

Although not shown in detail, the volume inside the conveying pipe 5 gradually decreases toward its upper end in order to efficiently drain water from the kitchen waste. As a method, the diameters of the conveying pipe 5 and the screw 6 may be gradually reduced as they go upward, or the diameter of the conveying pipe 5 and the screw 6 may be
Increase the diameter of the shaft. Furthermore, there is a method of increasing the helical pitch of the screw 6. In this example.

Inside the conveyor pipe 5, there are an appropriate number of slit grooves along its axis that efficiently return drained water to the container 3 and act as a resistance against the kitchen waste rotating integrally with the screw. It is formed.

A garbage bag 8 made of a 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 13 provided at the front of the sink 1, but in this case, the case 13 can be pivoted by a hinge 14 provided at the lower part of the back side. Supported. In addition, a magnetic plate 15 is provided on the upper part of the back side of the case 13.
A magnet 16 that is connected to the plate 15 and a microswitch 17 that is turned on and off depending on the inclination angle of the case 13 are arranged on the case side of the device.

Referring again to FIG. 2, the kitchen waste container is located at the bottom of the container 3.
A drainage pipe 12 for discharging wastewater in the container is connected thereto. In this case, the drain pipe 12 has a kitchen waste receptacle that is connected to the kitchen waste inlet 5 so that the level of wastewater stored in the container 3 is
A trap 12a is provided to hold it above point a.

Next, the operation of this device will be explained. First, the lid 13a of the case 13 is opened, and the garbage bag 8 is attached to the garbage outlet 5b of the conveying pipe 5 using the attachment 9, and the attachment 113a is closed. At this time, since almost no weight is applied to the case 13, the case 13 is held in its normal position by the magnet I6, and the microswitch 17 is turned on. This state is maintained until a predetermined weight of garbage is accumulated in the garbage bag 8.

When kitchen waste is inputted from the kitchen waste input port 2 and the screw 6 is rotated by the motor 7, the kitchen waste is transported through the conveying pipe 5 by the screw 6, and after being drained on the way, it is delivered to the garbage bag 8 from the kitchen waste discharge port 5b. discharged inside. In this case, the kitchen waste is reliably taken into the conveying pipe 5 by the notched groove 10 formed on the outer periphery of the spiral blade 6a.

Further, large kitchen waste is cut into small pieces and taken into the conveying pipe 5. Note that even if a string-like object (for example, vegetable streaks, etc.) or a skin-like object (for example, onion skin, plastic packaging film, etc.) is caught in the notch groove 10, these objects will be removed by the claw 11. Removed from #10. In this way, the kitchen waste is processed and the kitchen waste is discharged from the kitchen waste outlet 5b.
However, as the weight increases, the case 13 resists the attraction force of the magnet 16 and tilts toward the front 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.

In addition, since the kitchen waste intake port 5a is submerged in the waste water stored in the container 3, the bad odor and foreign odor generated in the garbage bag 8 will not flow back to the sink 1 side.

〔Effect 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, by providing a cutout groove on the outer periphery of the helical blade exposed at the kitchen waste intake port of the screw, kitchen waste is efficiently taken in, and large kitchen waste is crushed and taken in little by little. Therefore, even relatively large amounts of kitchen waste can be processed within a short time.
