Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention uses waste heat for drying and reducing raw garbage by utilizing exhaust heat or residual heat of a burner of a heat generating device such as a gas bath combustor, a water heater or a stove. The present invention relates to a used garbage drying device.

[0002]

2. Description of the Related Art Conventionally, kitchen garbage from a home is almost always put in a polyethylene waste bag as it is, and taken out to a designated collection place on a designated collection date, which is then collected by a local government. Is collected and incinerated for disposal.

By the way, in recent years, with the advancement of eating habits and the progress of internationalization, the kinds of food materials are diversified, and the amount of raw garbage in the kitchen tends to increase.

Therefore, in households that produce garbage, the garbage contains a large amount of water and becomes bulky. Therefore, if the garbage is put in the garbage bag as it is, the amount of the garbage bag used becomes large, and the garbage bag will be decomposed during storage until the day of collection and will have a bad odor. Is causing problems such as.

On the other hand, in some cases, local governments that incinerate garbage dispose of raw garbage in excess of the processing capacity as the amount of garbage increases, and in addition, the water content of garbage reduces the incineration efficiency. Because of the inconvenience, the reduction of garbage is becoming a social problem.

[0006] Therefore, an object of the present invention is to provide a food waste drying apparatus which can perform drying and weight reduction of food waste at low cost and which utilizes waste heat and is suitable for home use.

[0007]

In order to solve the above-mentioned problems, according to the present invention, a hollow chamber provided in the middle of a smoke exhaust passage of a heat generating device, an opening provided in a peripheral wall of the hollow chamber, The apparatus for drying raw garbage comprises a lid provided so as to open and close the opening, and a basket for taking in and out of the hollow chamber through the opening.

[0008] In order to store the raw garbage in the kitchen and to quickly dry it with the hot exhaust gas in the smoke exhaust passage, the outer peripheral portion of the processing basket can be introduced with the high temperature exhaust gas, for example, made of wire mesh or punched. It is preferable to adopt a structure with holes.

Further, the heat generating device means, for example, a bath boiler, a water heater or a stove.

[0010]

In the apparatus for drying food waste utilizing waste heat configured as described above, for example, when food waste is generated in the kitchen, the food waste is thrown into the treatment basket, and the treatment car into which the food waste is thrown in is disposed. Open the lid of the hollow chamber and insert it through the opening, and close the lid to close the opening. Then, when the heat generating device is used, the raw garbage in the processing basket is dried due to the exhaust heat discharged from the smoke exhaust passage and the residual heat after using the heat generating device.
As a result, the amount of raw garbage is reduced and corruption is stopped.
When the garbage dries, open the lid, remove the processing basket from the hollow chamber, put the dried garbage from the processing basket into the garbage bag,
Dispose at the designated collection place as before.

[0011]

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

As shown in FIGS. 1 and 2, the apparatus for drying food waste utilizing waste heat according to the present invention comprises a hollow chamber 2 and a processing basket 7 housed in the hollow chamber 2.

As shown in FIG. 1, the hollow chamber 2 is provided in the middle of the chimney (exhaust pipe) of the outer pot 11 connected to the bath, that is, the smoke exhaust passage 1, and communicates with the smoke exhaust passage 1. In the case of the embodiment, the smoke exhaust passage 1 is the chimney of the outer pot 11 of the bathtub, but the present invention is not limited to this, and a chimney of a stove or an instantaneous water heater may be used.

The peripheral wall of the hollow chamber 2 is provided with an opening 3 for inserting and removing the processing basket 7. The opening 3 is
The lid 4 can be opened and closed freely, and this lid 4 is shown in FIG.
As shown in, the hinge 5 is attached so as to be rotatable left and right. Further, the lid 4 is locked by a hanging tool 6 which is tilted from an upright position to a horizontal position and dropped into and engaged with each other to maintain a closed state. The lid 4 can be opened and closed by a sliding method.

On the other hand, as shown in FIG. 3, the processing basket 7 housed in the hollow chamber 2 through the opening 3 has an outer peripheral portion formed of a wire mesh or a punching hole, and has an open upper surface to improve ventilation. In addition, it is easy to put garbage in.

Further, the processing basket 7 is, as shown in FIG.
A leg portion 8 is provided in a square on the bottom surface, and the leg portion 8 forms a gap between the bottom surface of the processing basket 7 and the bottom of the hollow chamber 2,
It is designed to improve smoke and hot exhaust gas passage.

Since the processing basket 7 is required to have heat resistance and corrosion resistance, it is preferable to use stainless steel as a material.

This embodiment is configured as described above. For example, when garbage is generated in the kitchen, the garbage is put into the processing basket 7, and the processing basket 7 containing the garbage is opened through the opening 3. It is placed in the hollow chamber 2 and the lid 4 is closed and the opening 3 is closed. Then, when the bath is used, the raw garbage in the processing basket 7 is dried by the smoke exhausted by the combustion of the burner 12 of the outer pot 11, the hot exhaust gas, and the residual heat after the use of the bath. At the stage of drying, take out the processing basket 7 from the hollow chamber 2,
Put the garbage inside in a plastic bag and discard. At this time, the amount of raw garbage is reduced by drying and the bulk is low. Therefore, the amount of the plastic bag used is small, and no odor is generated by drying.

Next, in order to examine the effect of this garbage drying device, the treatment basket 7 containing leftover food and vegetable waste was placed in the hollow chamber provided in the smoke exhaust passage 1 of the bathtub. Drying was performed and the water content was measured every hour.
The result is shown in FIG.

In this case, as a comparative example, raw garbage was drained and then packed in a plastic bag. Therefore, since there is no treatment, the weight loss is zero.

On the other hand, in the apparatus of the present embodiment, the weight reduction rate reaches 31% or more in the processing time of 15 minutes or more, and a great improvement in efficiency can be seen. Furthermore, it was found that the reduction rate reached 50% or more when the treatment time was 1 hour.

[0022]

[Effect] The present invention is configured as described above, and the hollow chamber is provided in the middle of the smoke exhaust path of the heat generating device, and the processing chamber for the garbage is accommodated in the hollow chamber. Drying and reducing the amount of raw garbage can be performed using heat and residual heat. Therefore, it is possible to dry and reduce raw garbage at a low running cost with an inexpensive device.

Therefore, since it can be promoted to general households, it can make a great contribution to the reduction of dust, which is a big problem in modern society.
