DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage processing apparatus, and more particularly to a bio-type garbage processing apparatus for decomposing garbage with microorganisms.

[0002]

2. Description of the Related Art Heretofore, there has been known a so-called bio-type garbage disposal apparatus in which garbage is decomposed by microorganisms. In this bio-type garbage disposal apparatus, the garbage is decomposed by introducing garbage into a processing chamber having a processing material containing microorganisms that decompose garbage. Air for the microorganisms to breathe and survive and air for evaporating and removing water contained in the garbage are required. Therefore, the garbage processing apparatus includes an intake path for taking in outside air into the processing chamber and an exhaust path for discharging air in the processing chamber to the outside, and further includes a ventilation power source for ventilating air into the processing chamber. The air in the processing chamber can be ventilated with the outside air by operating the ventilation fan. Further, a stirrer is provided in the processing tank, and the garbage and the processing material charged in the processing tank are mixed, and the mixture is appropriately stirred to remove all microorganisms contained in the mixture. Oxygen can be supplied. In this garbage disposal apparatus, if garbage is normally decomposed by the microorganisms, it is mainly decomposed into water, carbon dioxide, ammonia, and the like. At this time, in addition to the ammonia as an odor component, Nitrogen compounds such as amines, methyl sulfide, methyl mercaptan,
Odor gases such as sulfur compounds such as methyl disulfide and aldehydes are generated, but deodorizers are usually provided in the exhaust path, and air in the processing chamber containing these odor gases is purified by this deodorizer. After that, it is evacuated.

[0003]

By the way, in a bio-type garbage disposal apparatus, the temperature of a mixture of garbage and the above-mentioned processing material, the amount of water retention, and the supply of oxygen from the outside air are adjusted to promote the propagation of the microorganisms. The garbage decomposition process can be performed in an optimal state. However, when the ventilation cannot be performed properly due to poor ventilation due to a failure of the ventilation fan, or a sudden change in temperature or humidity of the outside air, and the state of the garbage and the processing material deteriorates, the microorganisms cannot survive. Garbage does not undergo normal decomposition processing and rots. When garbage rots, in many cases, the garbage becomes muddy and sludge-like, and the odor increases compared with the case where it is decomposed by the above-mentioned microorganisms, so-called putrid odor.
This rotten odor generally has a different odor compared to the case of normal decomposition treatment, that is, it is considered that the component ratio and the type of the odor gas which is a component of the odor are different. There was a risk of exceeding the purification capacity and leaking to the outside.

The present invention has been made in view of the above circumstances, and an object of the present invention is to detect deterioration of the state of decomposition of garbage at an early stage, to promote the decay of garbage and to prevent odor leakage. It is an object of the present invention to provide a garbage disposal apparatus that can prevent the garbage from being discharged.

[0005]

According to the present invention, there is provided a garbage processing apparatus comprising: a processing chamber having therein a processing material containing microorganisms for decomposing garbage; an intake path for taking in outside air into the processing chamber; In a garbage disposal apparatus including an exhaust path for discharging indoor air to the outside, a ventilation fan for ventilating air into the processing chamber, and a stirrer for stirring the processing material and garbage, the operation of the stirrer is performed. with at providing a detector for detecting a load applied to the stirrer拌器, provided a determining unit a case where a smaller load than and lower limit lower limit is set for a load according to the stirrer was detected above the detection unit , Judge decrease in load level applied to the stirrer
It was possible manner is characterized in.

In this garbage disposal apparatus, the processing state of the garbage stirred together with the processing material is detected using the agitation degree of the stirrer as an index, and the garbage is putrefied. Can be determined. That is, as described above, the garbage becomes slimey when it is putrefied, so that the load on the stirrer is reduced as compared with the case where the microorganism is normally decomposed by the microorganism. . The present invention utilizes such a phenomenon, and sets a lower limit at which garbage rot is estimated at the level of the load applied to the stirrer, and sets the lower limit of the load detected by the detection unit. When the level becomes smaller than the lower limit, the deciding device determines the garbage decay.

The type of stirring of the stirrer is not particularly limited. For example, a stirrer of a type in which the processing material and the garbage are stirred by rotating a stirring blade can be used. in this case,
The detection unit may detect a load value applied to the stirring blade as an index of a load applied to the stirrer, or may detect a rotation speed of the stirring blade. In the case of the former, the lower limit of the load value applied to the stirring blade is set in the determiner, and it is preferable that the detector detects a load value smaller than the lower limit. In the latter case, the determination unit may set an upper limit value of the rotation speed of the stirring blade and determine whether the detection unit detects a rotation speed greater than the upper limit value.

[0008] The garbage disposal apparatus according to the present invention may be provided with an alarm means for issuing an alarm in response to the judgment of the above-mentioned judging device. Can be recognized. The alarm means is not particularly limited, but may be, for example, one that emits a visual alarm such as lighting of an alarm lamp, or one that emits an alarm sound.

In the garbage disposal apparatus according to the present invention, it is preferable that the ventilation fan is stopped and the exhaust path is shut off in response to the determination by the determination unit. In this case, it is possible to automatically prevent the rotten odor emitted from the rotten garbage from leaking to the outside.

Further, the garbage processing apparatus according to the present invention may be one in which a heating device is provided in the processing tank so that the temperature of the processing material and the garbage can be adjusted. It is preferable that the heating device be stopped in response to the determination by the determiner. In this case, by setting the temperature of the garbage decomposed by the microorganisms in the processing material to a temperature suitable for the propagation of the microorganisms, the decomposition of the garbage can be promoted, but for some reason. If the garbage is spoiled, heating the garbage will further promote spoilage. Therefore,
In order to prevent this, the heating device is stopped in response to the determination by the determiner.

A ventilation fan 5 serving as a ventilation power source is provided around the exhaust outlet of the exhaust path 4. By operating the ventilation fan 5, outside air is taken into the processing chamber 1 through the intake path 3 and processed through the exhaust path 4. The air in the chamber 1 is discharged to the outside. In addition, a deodorizing device (not shown) is provided in the exhaust path 4 so that odor contained in the exhaust can be purified.

In the garbage disposal apparatus, the stirrer 7 at the time of operation is used.
Is provided on the rotating shaft of the stirring blade 71, and a lower limit of the load applied to the agitator 7 can be arbitrarily set at a lower portion on the outer side wall of the processing chamber 1 and a load lower than the lower limit can be set. Is determined by the detecting unit 8 for determining whether or not the detection is performed. The detector 8 includes a stirrer 7 at the time of operation.
As an index of the load applied to the agitating blade 71, a type that detects the load value applied to the rotating stirring blade 71 is used. On the other hand, the lower limit of the load value applied to the stirring blade 71 can be set in the determiner 9 and this lower limit is set. What determines the case where the detection unit 8 detects a load value smaller than the value is used.

Here, in addition to the above-mentioned type, a type that detects the number of revolutions of the stirring blade 71 as an index of the load applied to the stirrer 7 during operation can be used as the detecting unit 8. The vessel 9 can set an upper limit of the number of revolutions of the stirring blade 71 and determines the case where the detector 8 detects a number of revolutions larger than the upper limit. In addition, the installation positions of the detection unit 8 and the determination unit 9 are not limited to the above positions, and can be appropriately changed. Further, in the present embodiment, the detection unit 8 and the judgment unit 9 are provided separately, but they may be provided as an integral part.

In the garbage disposal apparatus, an alarm device 10 for issuing an alarm in response to the judgment of the judging device 9 is provided at a lower portion outside the side wall of the processing chamber 1. Examples of the alarm device 10 include a type that emits an alarm sound and a type that emits an alarm lamp. In addition, this alarm 1
It goes without saying that the installation position of 0 is not limited to the above-mentioned position and can be changed.

In the garbage disposal apparatus, as described later, it is possible to judge at an early stage whether the garbage 6 has decomposed due to the failure of the microorganisms in the processing material 2 to decompose the garbage 6 normally. You can do it.

First, the operation when the garbage processing apparatus normally processes garbage will be described.

In the garbage processing apparatus, the garbage 6 introduced into the processing chamber 1 is decomposed by the microorganisms in the processing material 2 multiplying it as a nutrient source. By operating the ventilation fan 5, the inside of the processing chamber 1 is ventilated. In addition, the stirrer 7 is operated at regular intervals from the time when the garbage 6 is charged, whereby the garbage 6 and the processing material 2 are stirred. The ventilation is performed for the purpose of removing excess water contained in the mixture of the garbage 6 and the processing material 2 and supplying oxygen for respiration of the microorganisms. 6, the water contained in the mixture of the garbage 6 and the processing material 2 becomes excessive due to the water originally contained in the garbage 6 and the water generated by the decomposition of the garbage 6, and the microorganisms do not work effectively. Is prevented from becoming oxygen-deficient and the microorganisms cannot survive.
The stirring is performed not only for mixing the garbage 6 with the treatment material 2 but also for efficiently removing moisture by the ventilation and supplying oxygen to the microorganisms.

In the bio-type garbage processing apparatus, if the ventilation in the processing chamber 1 and the stirring by the stirrer 7 are normally performed, and the temperature, the amount of moisture, and the supply of oxygen are appropriately performed, the garbage 6
Is mainly water, carbon dioxide,
Decomposed into ammonia and the like. At this time, in addition to the above-mentioned ammonia, nitrogen compounds such as amines, sulfur compounds such as methyl sulfide, methyl mercaptan, and methyl disulfide, and odor gases such as aldehydes are simultaneously generated as the odor components.
These odor gases are sources of irritating odor and odor,
Exhaust from the processing chamber 1 is purified by a deodorizing device provided in the exhaust path 4 and then discharged, so that odor is prevented from leaking to the outside.

Next, the operation when the garbage 6 to be processed in the garbage processing apparatus is spoiled will be described. The decay of the garbage 6 occurs when the microorganisms in the processing material 2 are difficult to survive due to the deterioration of the temperature, the amount of water, and the state of oxygen supply. It is conceivable, for example, that the temperature, moisture content, and oxygen supply state of the mixture of the garbage 6 and the processing material 2 due to ventilation cannot be appropriately controlled due to the trouble 5 or the influence of the temperature and humidity of the outside air.

When the garbage 6 becomes spoiled, it liquefies into a sludge-like sludge. Then, the load on the stirrer 7 during the stirring operation decreases accordingly. The garbage disposal apparatus makes it possible to judge the decay of the garbage 6 at an early stage by utilizing such a phenomenon. That is, the garbage disposal apparatus detects a load applied to the stirrer 7 and reduces the load level. A lower limit is provided, and when the load level falls below the lower limit, the decay of the garbage 6 is estimated. Specifically, the detection unit 8 provided on the rotating shaft of the stirring blade 71 detects a load value (or the number of rotations of the stirring blade 71) applied to the stirring blade 71, and provided on the outside of the side wall of the processing chamber 1. Determined 9
In the above, the lower limit of the load value applied to the stirring blade 71 (or the upper limit of the rotation speed of the stirring blade 71) is provided, and the detection unit 8 sets the load value smaller than the lower limit (or the rotation speed larger than the upper limit of the rotation speed). ) Is determined.
Then, an alarm is issued from the alarm device 10 in response to the judgment by the judging device 9, and the user of the garbage disposal device is provided with the garbage 6.
Is informed of the corruption.

Here, the stirrer 7 set by the determiner 9
The lower limit of the load at is set to a value appropriate for estimating the decay of the garbage 6. The determination of the lower limit of the load may be arbitrarily set by the user, or may be automatically set by a program. The load applied to the stirrer 7 is considered to be different on a case-by-case basis depending on the size, amount, shape, etc. of the garbage 6. May be determined on the basis of the load level when the stirrer 9 is operated for the first time.

As described above, in the garbage disposal apparatus,
It is possible to judge the abnormality that the garbage 6 rots at an early stage, and to perform maintenance before the rot goes further, and the odor of rot exceeds the purification capability of the deodorizing device and leaks to the outside. Can be prevented before they occur.

FIG. 2 is a schematic diagram showing an outline of a garbage disposal apparatus according to a second embodiment of the present invention. As shown in the figure, the garbage processing apparatus according to the second embodiment is different from the garbage processing apparatus according to the first embodiment in that an intake port opening / closing valve 11 is provided at an opening of the intake path 3 on the processing chamber 1 side, and exhaust gas is exhausted. An exhaust port opening / closing valve 12 is provided at an opening of the path 4 on the processing chamber 1 side. Then, the ventilation fan 5 is stopped in response to the determination by the determiner 9, and the intake port opening / closing valve 11 and the exhaust port opening / closing valve 12 are closed so that the inside and outside ventilation is closed. Is controlled to stop the operation.

In the garbage disposal apparatus, when the decay of the garbage 6 is judged by the judging device 9, the alarm device 10 issues an alarm in response to this judgment, and furthermore, the ventilation in the processing room 1 is performed. Is stopped and the inside of the processing chamber 1 is closed from the outside.
It is possible to automatically prevent the putrefaction odor of the garbage 6 in the processing chamber 1 from leaking to the outside.

FIG. 3 is a schematic diagram showing an outline of a garbage disposal apparatus according to a third embodiment of the present invention. As shown in the figure, the garbage processing apparatus according to the third embodiment is different from the garbage processing apparatus according to the second embodiment in that a heater 13 is provided in the processing chamber 1 as a heating device for heating the garbage 6 and the processing material 2. Is provided at the bottom. Then, in response to the determination by the determiner 9, the ventilation fan 5 is stopped and the intake port opening / closing valve 11 and the exhaust port opening / closing valve 12 are closed to close the inside and outside ventilation. 13 is controlled so as to stop the operation of the whole garbage processing apparatus including the garbage disposal apparatus 13.

In the garbage disposal apparatus, when the garbage 6 is normally decomposed, a mixture of the garbage 6 and the processing material 2 which tend to be cooled by ventilation or evaporation of water is supplied to the heater 13. Is activated to warm the microorganisms in the treatment material 1 to a temperature at which the microorganisms can easily propagate, thereby activating the activities of the microorganisms and promoting the decomposition treatment of the garbage 6. On the other hand, when the deciding device 9 determines the decay of the garbage 6, as in the second embodiment, the alarm device 10 issues an alarm in response to this determination, Although the ventilation is stopped and the inside of the processing chamber 1 is closed from the outside, the heater 13 is also stopped so that the heater 13 does not promote the spoilage of the garbage 6.

[0029]

According to the garbage disposal apparatus according to the present invention,
Using the degree of stirring in the stirrer as an index, the processing state of the garbage stirred together with the processing material can be detected to determine the decay of the garbage. That is, the detection unit detects that the load applied to the stirrer is reduced due to the garbage being putrefied and liquefied into a muddy sludge, and the load level is determined by the determiner. By determining that the rot of the garbage has decreased to the estimated level, the rot of the garbage can be determined at an early stage. In this way, the decay of the garbage can be determined at an early stage, so that it is possible to perform maintenance before the situation is further deteriorated, and it is also possible to prevent the leakage of odor to the outside beforehand. .

In the garbage disposal apparatus according to the present invention,
In the case where an alarm unit that issues an alarm in response to the determination of the above-described determiner is provided, the user of the garbage disposal device can be made to recognize the decay of the garbage.

In the garbage disposal apparatus according to the present invention,
When the ventilation fan is stopped and the exhaust path is shut off in response to the determination of the determiner, it is possible to automatically prevent the rotten odor generated from the rotten garbage from leaking to the outside.

Further, in the garbage disposal apparatus according to the present invention,
When a heating device is provided in the processing tank to adjust the temperature of the processing material and the garbage, by stopping the heating device in response to the determination of the determiner, It is possible to prevent a problem that the spoiled garbage is heated to further spoil the spoilage.
