As shown in FIG. 1, this kitchen waste processing apparatus includes a cylindrical kitchen waste container 3 having a kitchen waste inlet 2 provided at the bottom of a sink 1. In this kitchen waste receptacle, a drainer 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 lower end of the transfer pipe 5, and a kitchen waste outlet 5b is provided at the upper end of the transfer pipe 5. According to this embodiment, the bottom of the colander 4 fits around the kitchen waste intake port 5a.

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.

Although not shown in detail, in order to efficiently drain water from kitchen waste, the volume of the inside of the conveying pipe 5 is increased.

It gradually becomes smaller towards the top. As a method for this, the diameters of the conveying pipe 5 and the screw 6 are gradually made smaller as they go upward, or the diameter of the shaft of the screw 6 is made thicker. 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 on the front side 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 1 is provided on the upper part of the back side of the case 13.
5 is provided, and the same plate 15 is provided on the housing side of the device.

Referring to FIG. 3, which shows an example of this, the filter detecting means is a magnet 21 provided on the filter 20 side, and the kitchen waste receptacle is a magnet 21 provided on the container 3 side opposite to the magnet 21. A proximity switch 22 is provided. 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. FIG. 4 shows another example of the filter detection means. That is, in this example,
The kitchen waste receptacle is equipped with a microswitch 23 provided on the container side so as to mechanically contact the filter 20 and turn on/off as the filter is attached or removed. In this case, a hole 3a for inserting the operating rod 23a of the microswitch 23 will be bored in the container 3 of the kitchen waste container, but the opening 3a
A rubber cover 25 is attached to prevent water leakage. In addition, as other filter detection means, an optical sensor, an ultrasonic sensor, an electrostatic sensor, etc. are illustrated.

Next, the operation of this device will be explained. first.

Open the lid 13a of the case 13, attach the garbage bag 8 to the garbage 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 13, the case 13 is held in its normal position by the magnet 16, 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. Large kitchen waste is cut into small pieces by the edge of the kitchen waste intake port 5a 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 discharge port 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 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.

By the way, when the filter 20 is removed during operation, a stop signal is output to the motor 7 from the filter detection means, for example the magnetic proximity switch 22.

Similarly, with the filter 20 removed, the motor 7 will not start even if the start button is pressed.

According to this device, the kitchen waste intake port 5a is submerged in the wastewater stored in the container 3, so that 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, in the present invention, since operation is stopped when the filter is removed, sufficient safety is ensured. Furthermore, the effects are remarkable, such as being able to automatically dispose of kitchen waste without the need for human intervention.
