DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposal machine for reducing the amount of garbage generated in a kitchen of a general household by decomposing or fermenting and decomposing the garbage using an aerobic bacterium or other decomposing bacteria. The present invention relates to a method for removing contents such as a base material.

[0002]

2. Description of the Related Art A substrate and a fermentable aerobic bacterium are placed in a processing tank provided with a stirrer and a ventilator, and garbage is put into the processing tank and agitated. A garbage processing machine that reduces the amount of garbage by fermenting and decomposing the garbage to be treated has attracted attention as one method of improving the environmental pollution problem in recent years, and the number of users has gradually increased. By the way, if the garbage disposal is continued by using such a garbage disposal apparatus based on the fermentation decomposition action, the base material is deteriorated and the life is exhausted, and the fermentation decomposition action cannot be performed. A so-called "substrate exchange operation" is required in which old substrates and processed products are taken out and exchanged for new substrates.

[0003] A general garbage disposal machine employs a system in which an openable / closable base material take-out port is provided at the bottom of a processing tank, and an old base material and a processing product are taken out from the base material take-out port. However, such a kitchen waste disposal machine has the following problems.

[0004] (1) The old base material and the processed product may be formed into a sticky miso containing a large amount of water, solidified into a dumpling, or an inner periphery of a processing tank, depending on the use conditions. In order to change to various states, such as a state in which the layer is firmly adhered to the wall in a layered manner, it may not be easily taken out from a small base material outlet at the bottom of the processing tank.

(2) If an old substrate and a processing product are taken out from a base material taking-out port at the bottom of the processing tank and the lid is forgotten to be closed or the lock is incomplete, the base material leaks out during operation. Sometimes.

(3) When garbage with a large amount of water is put into the processing tank, dirty liquid may flow out from the joint of the base material outlet at the bottom of the processing tank.

(4) If the child mischievously opens the cover of the base material taking-out opening at the bottom of the processing tank provided on the front of the machine, the base material and processing products may leak or may be rotating. Risk of injury by touching the stirring blades.

(5) Insects such as maggots may propagate by taking in oxygen from the gap at the base material outlet at the bottom of the treatment tank.

Japanese Patent Application Laid-Open No. 8-47681 discloses that
There is disclosed a garbage processing machine in which a processing tank rotatably provided on a machine body is inclined to take out a processed product.

[0010]

By the way, as in the above-mentioned conventional example, the processing tank rotatably provided on the machine body is tilted so that the old base material and processing products in the processing tank are taken out from the upper end opening. Garbage disposal machines require a rotation support mechanism that rotates the heavy treatment tank and supports it in a predetermined posture. As the number of failures increased, so did the causes of failure.

By the way, the simplest method for taking out the contents of a container is to take the container upside down and use gravity. This method is simple and very effective if the container is small and lightweight. However, if the container cannot be lifted together with the contents of the container, and is of a size and weight such as, for example, a kitchen waste treatment tank provided with a stirring mechanism and a ventilation mechanism, the contents, In this case, the substrate and the processed product cannot be discarded. To solve the problem, it is conceivable that the apparatus incorporating the processing tank is laid down and laid on its side to take out the contents. However, when the apparatus is laid down, the weight is supported by the outer side surface of the processing tank or the side surface of the apparatus. When supporting the weight in this way, there is no problem as long as the surface can be damaged, but if it is a metal or synthetic resin material, or if it is painted on it, the surface will be scratched I can't deny it. Such scratching of the surface is unpleasant for the user, and in such a state, it is impossible to provide a product which is used for a long time.

The present invention has been made in view of such a situation of the prior art, and a first object of the present invention is to eliminate a mechanism for removing contents such as a base material and to easily remove contents. It is an object of the present invention to provide a low-cost kitchen waste treatment apparatus which can be used comfortably for a long period of time.

It is a second object of the present invention to provide a method of removing a base material excellent in usability, in which contents such as a base material can be easily taken out using the apparatus.

[0021]

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

FIG. 1 is a vertical sectional front view showing an embodiment of a kitchen waste disposal machine according to the present invention, FIG. 2 is a vertical sectional side view, and FIG. 3 is a vertical sectional rear view.

In this kitchen waste treatment machine, a processing tank 1 having an open upper end and a stirring blade 2 disposed at a central portion in the processing tank 1 are provided in an outer case 40 which is a frame constituting an outer shell of the body. Then, the substrate 3 and the aerobic bacteria are placed in the treatment tank 1. The base material 3 is mainly composed of sawdust or rice hull, which is mainly composed of fibrous materials such as lignin, which are hardly biodegradable. Each particle is porous and has water absorption and voids. Also, a material having a large void is used.

The stirring blade 2 is driven by a driving motor 5 via a transmission mechanism 6 such as a chain or a belt to rotate the rotating shaft 4 thereof.

The upper side wall of the processing tank 1 is provided with an intake port 11 open to the atmosphere and an exhaust port 12 connected to the ventilation fan 10. By operating the ventilation fan 10, water vapor and various gases in the processing tank 1 are sucked out from the exhaust port 12, discharged to the outside through the exhaust duct 14, and freshly introduced into the processing tank 1 via the intake port 11. Inhale the air. Inlet 11
And a filter (not shown) in the exhaust port 12
To remove odors and remove harmful gases.

The charging port 20 is for charging the garbage into the processing tank 1,
An opening for scraping out the aged base material (including the processed product) 3 and covered with the 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 to shut off the power of the drive motor 5 and stop the rotation of the stirring blade 2. To be configured.

In the garbage processing machine configured as described above, the moisture content of the base material 3 in the processing tank 1 is adjusted to 40 to 60%, aerobic bacteria are added and stirred, and the aerobic bacteria propagate. A hotbed for Thereafter, the outer lid 21 is opened and closed as needed, and kitchen waste is put into the processing tank 1.

The inside of the processing tank 1 automatically repeats stirring and ventilation at predetermined intervals by automatic control by the control device 30. Thereby, the garbage put into the treatment tank 1 is crushed by being stirred with the base material 3 and is rubbed by the jagged particles of the base material 3 and worn, and the aerobic bacteria adhere to the surface. The aerobic bacteria breed by eating the garbage as food. As a result, the garbage is fermented and broken down into pieces,
Most of the water is emitted as water vapor and carbon dioxide, and a part of the water is decomposed and decomposed into low-molecular-weight products that become nutrients for plants, that is, compost remains in the base material 3 as solids.

The generated gas includes a small amount of a gas such as ammonia or trimethylamine which causes a bad smell. These water vapor, carbon dioxide and other gases
At the stage of ventilation, the air is discharged from the processing tank 1 to the outside of the kitchen waste treatment machine by the ventilation fan 10. Of course, gas or harmful gas that causes a bad smell is removed by a filter attached to the exhaust port 12. Such an operation is intermittently performed by automatic operation control.

Although there is a difference in the length of time for such a garbage disposal operation depending on the use conditions, if it lasts from three to six months,
Decomposition treatment of kitchen waste Adults accumulate, or the base material 3 becomes viscous and sticky due to deterioration of air permeability and increase in moisture content due to deterioration or wear of the base material 3 causing deterioration. The treatment tank 1 is solidified into a dumpling state, or firmly adheres to the inner peripheral surface of the processing tank 1 in a layered manner. In such a state, the anaerobic bacteria become incompatible with the propagation of aerobic bacteria, the fermentation decomposition activity becomes low, and the function of the anaerobic bacteria gradually increases in the base material 3, causing putrefaction odor.
In such a state, the life of the substrate 3 has expired. In this way, when the base material 3 has deteriorated and its life has expired, a so-called “base material replacement operation” for removing the old base material 3 from the processing tank 1 and replacing it with a new base material 3 is required.

In the kitchen waste disposal machine according to the present invention, the old base material (including the processed product) 3 is taken out from the inlet 20 and various improvements are made to make it easy to take out.
That is, as shown in FIG. 1, the base of the processing tank 1 is not provided with a base material take-out port that causes leakage of the base material 3 or moisture,
As shown in FIG. 4, the airframe was turned sideways to scrape out the old base material 3 in the processing tank 1 from the input port 20 which is the upper end opening of the processing tank 1.

For this purpose, as shown in FIGS. 1 to 3, all the mechanical parts are arranged in a space below the processing tank 1, and
No flange member forming the upper end opening of the processing tank 1 is exposed as it is without providing any member such as a top cover which narrows the upper end opening forming the inlet 20 of the processing tank 1. The entrance of the flange forming the opening (the inner edge 20a of the opening) was enlarged in a tapered shape and connected to the upper end opening of the outer case 40. Therefore,
The old base material 3 can be naturally scraped out smoothly without being caught in the opening of the processing tank 1 of the machine body that has been turned over. Moreover, the old base material 3 is not left in the processing tank 1. In addition, as shown in FIG. 2, the outer lid 21 which is a hindrance to the side-down is made detachable so that the body can be easily turned sideways, and the outer lid 21 is removed when the substrate 3 is taken out of the processing tank 1. Have to be able to. Thereby, the work of removing the old base material 3 from the processing tank 1 is further facilitated.

Also, when the body is tilted sideways, a convex surface is provided so as to specify a surface to be grounded to the floor surface 42 so that an unspecified portion of the outer case 40 does not contact and damage the floor surface 42. 41 are provided. As a result, when the aircraft is turned sideways, the convex surface 41 comes into contact with the floor surface 42 to support the aircraft, so that the aircraft can be tilted on any floor surface 42 with ease.

Further, according to the present invention, when the body 3 is tilted sideways and the substrate 3 is taken out, the intake port 11 and the exhaust port 1 are removed.
By attaching a cover 13 covering the filter 2, there is no danger that the powder of the base material 3 generated when scraping out enters the intake port 11 and the exhaust port 12 and adheres to the filter.

As described above, the kitchen waste treatment machine of the present invention is simpler and faster than the conventional kitchen waste treatment machine, in which the old base material 3 is taken out from the base material outlet at the bottom of the processing tank 1. "Substrate replacement work" can be performed neatly. In addition, there is no need for a rotation support mechanism for rotating the heavy processing tank or supporting the processing tank in a predetermined posture, and a solid kitchen waste processing machine can be provided with a simple mechanism.

In addition, since the configuration in which the tapered flange portion formed so as to enlarge the upper end opening of the processing tank 1 is directly exposed increases the opening area of the upper end, the operation of putting the kitchen waste into the processing tank 1 and It also has the effects of facilitating the confirmation of the processing status in the processing tank 1 and facilitating the work of removing foreign substances, and can constitute an extremely easy-to-use kitchen waste disposal machine.

Since the convex portion is provided so as not to be damaged, the contents in the processing tank can be scraped out without damaging the kitchen waste processing machine even if the kitchen waste processing machine body is turned over. Accordingly, a mechanism for removing the base material is not required, the strength of the kitchen waste disposal machine can be secured with a simple structure, and the weight and cost can be reduced. Further, since the main body is not damaged, it can be used comfortably for a long period of time.

According to the second aspect of the present invention, the projection is provided near the opening of the processing tank, and the kitchen waste treatment machine main body is supported between the bottom of the kitchen waste treatment machine main body and the projection. In addition, the kitchen waste disposal machine can be supported, and scraping can be easily performed.

According to the third and fourth aspects of the present invention, the processing tank is formed to have the same size or a large size toward the opening, or the inner edge of the opening of the processing tank expands outward. The contents can be scraped out smoothly and neatly.

According to the fifth aspect of the present invention, since the lid for closing the opening of the processing tank is detachably provided from the opening, the lid is removed at the start of the work of scraping the base material. You can work without your body getting in the way.

According to the sixth aspect of the present invention, the garbage processing machine is turned over to support the garbage processing main body using the convex portion,
Since the contents are scraped out of the processing tank opened in the lateral direction, the contents can be easily and reliably removed from the processing tank. At this time, since the side of the kitchen waste disposal machine is not damaged, it can be used comfortably for a long period of time.

According to the seventh aspect of the present invention, when the kitchen waste disposal machine is turned over, the intake and exhaust ports of the ventilation means opened in the processing tank are covered with the cover, and the contents are contained in the intake and exhaust ports. As it is scraped out so that it does not enter, the contents do not invade other mechanism parts during scraping work,
The contents can be reliably removed. Further, since the contents do not invade other mechanism parts, scraping out the contents does not cause a failure.
