Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food waste disposer which improves environmental hygiene by preventing discomfort such as insects jumping out of a fermenter when food waste is thrown in.

[0002]

2. Description of the Related Art Food waste discharged from homes and the food service industry is mainly disposed of by incineration or landfill. Incineration requires final disposal of exhaust gas and incinerated ash, and landfill has many environmental conservation issues such as groundwater pollution and difficulty in location.

The method of composting raw garbage is mainly a method of mixing and stirring in which fermenting is carried out by contacting with oxygen while heating under forced stirring, a method of fermenting in a standing state and a method of fermenting in a standing state or intermittently mixing in a state of being deposited. It is broadly classified as a semi-static fermentation method in which contact with oxygen is repeated. As examples of the former, JP-A-61-281091 and JP-A-60-255686.
There is a gazette.

An example of the latter is JP-A-54-101769.

Further, as an example of preventing the generation of flies by fermenting and decomposing with aerobic microorganisms, JP-A-54 is used.

Generally, the temperature in the fermenter of a food waste processor is maintained by fermentation by microorganisms and a heater for speeding up the fermentation. The temperature is a suitable environment for insect development and growth. Also,
When throwing in garbage, it is easy for insects to enter with it. There is a problem in hygiene, because the insects that have entered the inside will either pop out again when the garbage is put in, or they will propagate in the fermenter and pop out, causing discomfort.

It is an object of the present invention to kill insects that fly out when the lid is opened or closed when throwing food waste in the fermenter and prevent the insects from jumping out, thereby eliminating discomfort and improving hygiene. It is to provide the intended garbage processing machine.

[0008]

The feature of the present invention is that the insects which are generated in the fermenter of the food waste treatment machine which decomposes the food waste by the fermentation action of the microorganisms or which enter at the same time when the food waste is charged are A chemotactic substance such as a peculiar sex attractant (pheromone) or light irradiation is used to induce insects, and the insect is guided from the guide port of the collector into the collector to collect the insect. It is to kill the insecticide by spraying and irradiating with ultraviolet rays. The second feature is that dead insects are further reduced into the fermenter and fermented and decomposed.

[0009]

The present invention induces insects that enter at the time of opening and closing the lid when throwing food waste and insects generated in the fermenter by a method consisting of either an attractant or light irradiation or a combination of a plurality of them. It collects from the guide port of the collector into the collector, and the insecticide in the form of spray fills the inside of the collector to kill it, or it is irradiated with ultraviolet rays to kill it and prevent it from jumping out.

An attractant is one of the methods for attracting insects, and the insects can be easily collected by placing a sex attractant (pheromone) that insects prefer in the collector. The same effect can be obtained by using light. Insects can be collected in the light by introducing light into a part of the dark fermenter. The light is not particularly limited as long as it is a means capable of collecting light on the inner surface of the collector that contacts the outside of the fermentation tank. For example, a transparent material such as glass or plastic can be used as the material for the window surface.

Induction of insects by attractants and types of attractants,
The method of use is not particularly limited, but for example, a container containing an attractant may be installed inside the collector. The pesticide is not particularly limited as long as it is a pesticide or ultraviolet irradiation. For example, when killing insects induced by odor using a commercially available insecticide (eg, pyrethronoid), the insecticide (eg, pyrethronoid) inserted in the air pump is supplied at the pressure of the air pump and sprayed by a spray nozzle. By filling the inside of the collector with insecticide,
Can be effectively killed.

It is also possible to kill it by irradiating it with ultraviolet rays. It is not as potent as an insecticide against insecticidal effects, but it has an insecticidal effect by taking longer UV irradiation time. The irradiation time of ultraviolet rays is appropriately selected within a range in which the fermentation of the target insects is not substantially inhibited by the ultraviolet rays leaking from the collector and the insecticidal effect of the target insects is obtained.

EXAMPLES The present invention will be specifically described below with reference to examples.

(Embodiment 1) FIG. 1 shows a cross section of a food waste processing machine. A heater, a stirring blade, and the like are omitted in order to simply show the inside. The food waste disposer comprises a food waste disposer main body 4, an outer lid of the main body 2, an inner lid of a food waste input port 3, a collector 14, an operation lever 10 for dropping dead insects into a fermenter, and the like.
The inner lid 3 for the garbage input port is designed to be opened only when the garbage is inserted and is always closed. The raw garbage 1 drops from the raw garbage inlet inner lid 3 to the fermented product 5 in the fermenter and is mixed and stirred together. After confirming 11 insects that have invaded together with the raw garbage 1 from the inner lid 3 of the raw garbage inlet, the inner lid 3 of the raw garbage inlet and the outer lid 2 of the main body are closed. Inside the fermenter, 150 mm long × 150 mm wide
A collector 14 having a depth of 150 mm is installed. As a method of collecting insects, a sex attractant (pheromone), which is an insect attractant, was applied to the collector 14 in a odor source 15 {30 mm square dice shape. } The container was provided with a plurality of holes so that the odor was emitted. As a result of observing the inside of the collector 1 hour after the start,
8 to 10 animals gathered in the collector 14 as they entered through the attraction port 13 attracted by the smell. After that, the insecticide (pyrethronoid type) inserted in the air pump 6 is supplied at a pressure (10 L / min) of the air pump, and is sprayed from the tip of the spray nozzle 7 to form a spray 8 in the collector 14 to form the insecticide. Filled. As a result of observing the inside of the collector 14 one minute after spraying, all the insects were dead. Furthermore, the dead insect was returned to the fermenter by pulling the operation lever 10 for dropping the dead body of the insect, and was combined with the fermented product 5.

Example 2 Insects were induced by light irradiation. Light irradiation is natural light. The transparent glass plate 9 shown in FIG. 1 was provided so that the inside of the collector could be seen from the outside. In this case, the container of the sex attractant that is the attractant 15 was removed.
The garbage processor was installed in a place where sunlight could enter. Similar to Example 1, after confirming 11 insects that entered the garbage 1 through the garbage entrance inner lid 3, the garbage entrance inner lid 3 and the outer lid 2 of the main body were closed. One hour after the start, as a result of looking inside the collector 14, 6 to 7 insects were gathered. Thereafter, insecticidal treatment was carried out in the same manner as in Example 1. As a result of observing the inside of the collector 14 one minute after spraying, all the insects were dead. In addition, an operating lever 10 for dropping dead insects into dead insects
Was added to the fermenter to reduce it, and this was combined with Fermented Material 5.

(Example 3) Guidance was performed using artificial illumination as another method of light irradiation. In this case, the glass plate 9 in the collector 14 was covered with an opaque material to darken the inside of the fermentation tank. For lighting, one light bulb of 5 watts was installed in the collector 14.
Similar to Example 1, after confirming 11 insects that entered the garbage 1 through the garbage entrance inner lid 3, the garbage entrance inner lid 3 and the outer lid 2 of the main body were closed. After 30 minutes from the start, the opaque material was slightly shifted and the inside of the collector 14 was examined. As a result, 4 to 5 worms were recovered. Thereafter, insecticidal treatment was carried out in the same manner as in Example 1. As a result of observing the inside of the collector 14 one minute after spraying, all the insects were dead. Furthermore, the dead insects were returned to the fermenter by pulling the lever 10 for dropping the dead bodies of the insects, and put together with the fermented product 5.

(Embodiment 4) FIG. 2 shows a cross section of a food waste processing machine. One ultraviolet lamp 16 (6 watts) was installed in the collector 14. The other parts have the same structure as in FIG. Insect 1
The method of collecting 1 in the collector 14 is also the same as in the first embodiment. After collecting 10 to 12 insects 11, an ultraviolet lamp 16 (6 watts) mounted in the collector 14 was irradiated for 3 minutes. As a result, the insects were not yet killed. Furthermore, when irradiation was added for 5 minutes, it was 100% dead.

From the above examples, it was confirmed that the insects can be collected by using any one of an attractant and light irradiation or a combination of a plurality of them. For insect killing, the insecticide is sprayed and UV irradiation is applied to collect the insects in a collector.
An insecticidal effect of 0% was obtained.

EFFECTS OF THE INVENTION According to the present invention, insects generated in the fermenter of a food waste disposing machine or insects that intrude with the food waste at the same time may fly out again when the food waste is put in, which causes discomfort. It is accompanied by unsanitary problems. Therefore, this method can attract insects by using an attractant or light irradiation that insects prefer, collect the insects in a collector, and then kill the insects by applying an insecticide and ultraviolet rays in the collector. Furthermore, the dead insects are reduced and decomposed again in the fermenter.

As described above, the insects can be prevented from jumping out again when the garbage is put in, so that the discomfort can be eliminated and the sanitary condition can be used.
