DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposer for decomposing garbage generated in households, restaurants, food processing companies, and the like. It relates to a processing machine.

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Unexamined Patent Publication No.
A so-called garbage processing machine (composting mechanism) as described in Japanese Patent Publication No. 290171 has been proposed. This prior art,
A substantially box-shaped processing machine main body, a processing container provided in the processing machine main body, and a stirring means (stirring blade) provided in the processing container.
And a drive device (drive motor) for driving the stirring means
And a control device (control circuit) for controlling the driving device, and the garbage put into the processing container is used as a medium (carrier).
Decomposition treatment is performed by the fermentation action of the microorganisms mixed in the water to reduce the volume (reduce the volume). At this time, a weight detecting means (weight sensor) is provided at a lower portion of the main body of the processing machine.
By detecting that the weight of the processing machine body has become larger than a predetermined value, it is detected that the processing of garbage has become an abnormal state that is insufficient.

[0003]

In the above prior art, the abnormal operation of the garbage disposer is managed by a weight detecting means (weight sensor) provided at the lower part of the disposer body.

On the other hand, recent waste recycling (recycling)
Against this background, the so-called Food Recycling Law was promulgated in June 2000 for food-related items, and came into effect in May 2001. According to the Food Recycling Law, 20% of garbage generated within five years will be reduced to businesses that produce 100 tons or more of food waste annually among restaurants and food processors that generate commercial garbage. It is required to reduce. Under such a trend, it is essential for a food waste processing machine to accurately grasp and manage the food waste (decomposition) processing amount.

Here, the weight detecting means in the above-mentioned prior art is for managing abnormal operation as described above, and the detailed structure is not clearly shown, and a piezoelectric element for electrically detecting pressure is incorporated. However, there is no description about improving the detection accuracy. Therefore, it is difficult to accurately detect the amount of garbage disposal as described above.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a garbage disposer capable of accurately detecting a garbage disposal amount.

[0007]

Means for Solving the Problems (1) In order to achieve the above object, the present invention relates to a garbage processing machine for performing volume reduction processing of garbage, a processing machine main body, and a central portion of the processing machine main body. A garbage processing container provided in, a stirring means provided in the garbage processing container, provided on one side of the processing machine body,
A driving device for driving the stirring means; and a control device provided on the other side of the main body of the processing machine for controlling the driving device.

When detecting the amount of garbage disposal in the garbage disposal machine as a change in weight, for example, a weight detecting means such as a load cell is provided between the support portion on which the body of the processor is mounted and the body of the processor. At this time, since the garbage disposal container and the processing machine main body of the large-scale garbage processing machine for business use are large-sized structures, for example, the weight detection means is provided on one side and the other side of the processing machine main body on the support portion, respectively. Are arranged, and the whole of them is used to detect the total weight of the processing machine body.

Here, it is generally known that the smaller the maximum detected weight value of the weight detecting means such as a load cell, the more the detection accuracy can be improved. For example, if the load distribution in the processing machine main body is not uniform and may be biased to one side, a larger load is applied to the weight detecting means on the biased side. The maximum detected weight value must be set to a relatively large value. As a result, the detection accuracy of the weight detecting means is reduced accordingly. When all the weight detecting means are unified, the one having the largest maximum detected weight value is also arranged on the opposite side, and similarly the detection accuracy is reduced.

Therefore, in the present invention, a garbage disposal container is disposed in the center of the processing machine main body, and a driving device is disposed on one side of the processing machine main body and a control device is disposed on the other side of the container. The balance can be improved, the load can be prevented from being biased to one side of the processing machine body, and the load distribution can be made uniform throughout. As a result, the weight detection can be almost equally shared between the weight detection means on one side and the weight detection means on the other side, and the maximum detected weight value of each weight detection means can be reduced accordingly. Therefore, the detection accuracy of each weight detecting means can be improved, and as a result, the amount of food waste can be detected with high accuracy.

When transporting a garbage disposer by, for example, a forklift, a crane, a truck, or the like, the stability is often not so good because the inside of the treatment container is empty, and safety is ensured. However, in the present invention, since the weight balance of the main body of the processing machine can be improved as described above, the stability can be improved correspondingly, so that the burden on the operator can be reduced.

The exhaust gas from which the odor has been removed by passing through the deodorizing device 60 flows into the ultraviolet sterilizing unit 83 through the duct 82, is sterilized, and finally discharged to the atmosphere through the exhaust pipe 85. . At this time, the suspended matter in the deodorizing device 60 such as the deodorizing medium finely divided by the stirring is collected by the filter 86 (see FIG. 7), and is prevented from scattering outside the garbage processing machine.

Hereinafter, the effects obtained by the above configuration in the garbage disposer of this embodiment will be described. here,
In the garbage processing machine of the present embodiment, as described above, the lower frame 34 on which the processing machine main body 1 is mounted and the processing machine main body 1 (strictly, the upper frame 11 as the bottom surface of the processing machine main body 1). The load cells 35 are interposed at the four corners, and the amount of garbage is detected from the change in the total value of the detection results (that is, the weight of the processing machine body 1).

Here, the weight detecting means such as the load cell
It is generally known that the smaller the maximum detected weight value is, the more the detection accuracy can be improved. For example, in the present embodiment, when the load distribution in the processing machine body 1 is uneven and the load applied to the load cells 35 supporting the four corners is uneven, the load cell 3 receiving the largest load
5 is set to be equal to or greater than the applied load, and the maximum detected weight value of the other load cells 35 must be adjusted to this. As a result, the maximum detected weight value of each load cell 35 is set high, and the weight detection accuracy is reduced accordingly.

Therefore, in the present embodiment, a garbage processing container 10 is disposed substantially at the center of the processing machine main body 1, and the stirring means 13 in the processing tank is disposed on one side of the processing machine main body 1 with the garbage processing container 10 interposed therebetween. By disposing the device 21 and the power supply / control device 32 on the other side, the weight balance of the processing machine main body 1 becomes substantially uniform, the load distribution can be made uniform throughout, and the load is applied to one side of the processing machine main body 1. Can be prevented from being biased. Thus, the weight detection can be shared almost equally among the load cells 35, and the maximum detected weight value of each load cell 35 can be set low. Therefore, the detection accuracy of each load cell 35 can be improved, and as a result, the amount of food waste can be detected accurately.

When the garbage disposal machine is transported by, for example, a forklift, a crane, a truck, or the like, the processing medium in the garbage disposal container 10 is often taken out and emptied. If the weight balance of the processing machine main body 1 is not uniform, if the processing medium is extracted in this way and the overall weight is reduced, the instability becomes remarkable, and the labor burden of the worker to secure the stability is increased. growing. However, in the present embodiment, since the weight balance of the processing machine main body 1 can be made substantially uniform as described above, the stability is ensured accordingly, and the worker for ensuring the stability at the time of transporting the machine is used. Burden can be reduced.

In the above, a so-called biodegradable garbage disposer in which garbage is decomposed by microorganisms has been described as an example. The feature of the present invention is that, for example, input garbage is heated and its water content is reduced. The present invention can also be applied to a garbage disposer of another configuration such as a so-called dry garbage disposer for evaporating and reducing the volume. When the garbage is put into the processing machine body 1, the opening and closing lid 6 is driven to open and close.
There is no need to be limited to this, and it may be configured to be opened and closed manually, for example. Also, a so-called biological deodorizing type deodorizing apparatus using a deodorizing medium has been described as the deodorizing unit 2, but the present invention is not limited to this. For example, another deodorizing apparatus that performs deodorizing using activated carbon or the like may be used. In these cases, a similar effect is obtained.
