When the cleaning parts 40 are formed to a V shape, the lumps of the base materials 3 are collected at the center of the treating vessel of the agitating vanes 2 and may be discharged from a discharge path 18 when the agitating vanes 2 are rotated in a rotating direction (b).

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a garbage disposer.

[0002]

2. Description of the Related Art A garbage disposer of the type in which a culture substrate and an aerobic bacterium are placed and stirred in a treatment tank having a stirring blade and a ventilation device is disclosed in, for example, Japanese Utility Model Laid-Open No. 6-34784.
Prevention of clumping of the substrate on the inner wall of the processing tank is disclosed in Japanese Patent Application No. 7-80069, for example, in which a stirring blade is improved.

[0003]

However, in the garbage disposer, the cultivation base material wears out with use time, the corners become smaller, and the porosity decreases. In addition, minute soil-like organic substances formed by decomposition of garbage are clogged in these voids, so that air retention and ventilation are deteriorated. In addition, the evaporation of water inside is worsened, the water content increases, the viscosity increases, and the material becomes viscous.However, if the stirring is uneven, the wall of the treatment tank can be solidified, which is suitable for the growth of aerobic bacteria. Disappears. Instead, the growth of anaerobic bacteria becomes active, causing so-called putrefaction and foul odors. In addition, the torque required to rotate the stirring blade is significantly increased. For this reason, there is a drawback that the motor for driving the stirring blade and the transmission mechanism are overloaded, and a failure occurs relatively early. In addition, although there is stirring by the stirring blade as a method of reducing the stirring unevenness, the stirring unevenness is slightly generated in the gap between the stirring blade and the processing wall, and the base material is hardened. Therefore, in order to prevent bad smells and failures, it is desirable to remove the substrate and remove the lump of the substrate on the wall surface of the processing tank at the same time as removing the substrate when replacing the substrate. However, in the processing tank, there are obstacles such as a stirring blade and a stirring shaft for removing a substrate lump such as a stirring blade, so that there is a disadvantage that the work cannot be easily performed.

[0004]

Means for Solving the Problems In order to achieve the above object, the present invention relates to a garbage disposer of a system in which a culture substrate and an aerobic bacterium are put and stirred in a treatment tank having a stirring blade and a ventilator. After the substrate is taken out, the parts for cleaning the inner wall of the processing tank are mounted on the stirring blade.

[0005] The present invention relates to a garbage disposer in which a culture substrate and an aerobic bacterium are placed and stirred in a treatment tank having a stirring blade and a ventilation device. The disadvantage that the mass of the base material in the gap must be removed by using a scoop or the like to avoid stirring blades that hinder the cleaning is solved by cleaning using stirring.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing the whole of the principle of the garbage disposer of the present invention, FIG. 2 is a longitudinal sectional view of FIG. 1, FIG. 3 is a sectional view taken on line AA, and FIG. B sectional view,
5 is a longitudinal sectional view of FIG. 1, FIG. 6 is a sectional view taken along line CC of FIG. 5, and FIGS. 7 and 8 are sectional views of essential parts DD of FIG.

The treatment tank 1 is a garbage disposer having a stirring blade 2 in the center, in which a culture substrate 3 is contained. The culture substrate is made of fibrous material such as lignin that is difficult to biodegrade, and its main component is sawdust, fir pattern, etc., each of which is porous and has water absorption and space.
In addition, the grain shape is complicated, and large voids are formed between the particles.

The rotating shaft 4 is a rotating shaft of the stirring blade 2 and is rotated by a driving motor 5 via a transmission mechanism 6 such as a chain or a belt. Above the processing tank 1, a fan 1 for ventilation is provided.
0, an intake port 11, and an exhaust port 12 are provided. By turning the fan 10, fresh air is sucked into the processing tank 1 through the intake port 11, and the water vapor and various gases in the processing tank 1 are discharged to the outside through the exhaust port 12. Inlet 11
The exhaust port 12 is provided with a filter.
An outlet 15 for contents is provided at the bottom of the processing tank 1. Usually, a pull-out shutter 17 having a handle 16 is provided.
It is shielded by. Put your hand on the handle 16 and release the shutter 1.
When the contents 7 are pulled out, the contents of the processing tank 1 fall into the discharge path 18 from the discharge port 15, so that the contents can be taken out of the machine only by pulling out.

An input port 20 is an input port of garbage into the processing tank 1 and is opened by an outer lid 21. A door switch (not shown) is interlocked with the outer lid 21, and when the outer lid 21 is opened to a certain angle, the door switch is opened, the power supply of the motor 5 is turned off, and the stirring blade 2 is stopped. I have.

Here, as shown in FIG. 2, the cross-sectional shape of the treatment tank 1 has an arc portion of substantially a semicircle or more so that the whole of the culture substrate 3 is uniformly stirred with a light action. The rotation shaft 4 is provided so as to coincide with the center of the arc of the arc portion. A plurality of stirring blades are fixed to the rotating shaft 4. The cross-sectional shape of the stirring blade 2 is substantially triangular as shown in FIGS. 3 and 4, and one side thereof is arranged so as to be parallel to the rotation surface of the stirring blade 2. And stirring blade 2
Alternates between front and reverse. Thereby, the stirring blade 2
Even if the culture substrate 3 contains water and becomes a high clay, in any case of normal and reverse rotation, the culture proceeds as if to cut the substrate at an acute angle with respect to the rotating surface, so that it can be separated and rotated.
The rotating torque can be small, and the base material moves smoothly along the triangular slope, and is mixed and stirred. In particular, the forward / reverse rotation of the stirring blades 2 complicates the movement of the base material, and produces uniform and uniform stirring throughout.

On two wall surfaces parallel to the rotation surface of the stirring blade 2 of the processing tank 1, the stirring blade 2 faces the triangular cross section with one side 30 parallel to the wall surface and is arranged close to the wall surface. . The distance a between the wall surface and one side of the stirring blade 2 is set to 5 to 15 mm. As a result, since the viscous and viscous base material does not exert a pressing force on the base material when the stirring blades 2 move, the formation of a clumpy layer such as a mud wall on the wall surface is prevented.

However, as the substrate is used, a small amount of the base material is formed at a distance a between the wall surface and one side of the stirring blade 2. It is also necessary to clean the lump of the base material which is stuck to the inner wall surface. If this is not removed, there is a risk that a bad smell will be produced or an obstacle that will hinder the rotation of the stirring blade.

FIGS. 5 and 6 show a state in which a cleaning component 40 is attached to the tip of the stirring blade 2 in order to clean the lump of the base material on the inner wall surface of the processing tank 1. When the stirring blade is rotated as shown in FIG. 5, the brush 41 of the component 40 to be automatically cleaned hits the inner wall surface of the processing tank 1 and cleans the lump of the base material.

When the part 40 to be cleaned is shaped as shown in FIG. 7, when the stirring blade 2 is rotated in the direction of rotation b, the mass of the cleaned substrate is collected at the center of the processing tank of the stirring blade and automatically discharged. Fall into Road 18. When the stirring blade 2 is rotated in the normal or reverse direction as shown in FIG. 8, the mass of the cleaned base material moves up and down. Be depressed. Thereby, the lump of the base material on the inner wall surface of the processing tank 1 is easily cleaned, thereby preventing a bad smell due to the lump of the base material and hindering rotation of the stirring blade.

Further, in the present invention, as a method of setting the component 40 to be cleaned, a type that can be stored in the stirring blade 2 by folding or the like, a detachable type, or the like can be used. In addition, when the rotation direction of the stirring blades during normal stirring operation and during cleaning is different from forward / reverse rotation, only forward rotation, only reverse rotation, etc., by providing a switch or the like, the rotation direction of the stirring blades can be switched. . If this switch is linked with the drawer of the shutter 17, the user can perform cleaning without having to switch each time.

[0016]

According to the present invention, the disadvantage of the method of fermenting and decomposing at a relatively low temperature near normal temperature by using a culture substrate such as aerobic bacteria and sawdust is that, together with the use time, the wall of the treatment tank and the stirring The lump of the base material formed between the blades can be easily cleaned, and the odor and the trouble can be prevented.
