2. Description of the Related Art Kitchen waste generated in the kitchen has conventionally been disposed of by using a disposer that is crushed and flowed as it is to sewage, a garbage processing machine that is crushed and dehydrated and recovered, and a heating means such as a microwave or a heater or steam. Was completely incinerated or dried using a garbage disposal machine for recovery.

[0003]

These conventional kitchen garbage processing machines have the following problems.

The disposer has a remarkably high BOD of the treated wastewater, which imposes a burden on the sewage treatment plant. Considering the current low sewerage penetration rate in Japan, it cannot be said to be a preferable treatment method.

[0005] Since the garbage processing machine does not process the recovered crushed kitchen waste, it is likely to be putrefaction, which may cause a bad odor and cause harmful insects and pathogenic bacteria.

[0006] The kitchen garbage processor using a heating means is detoxified, deodorized and reduced in weight by incineration or drying, and there is no problem of the above-mentioned decay, but it is very difficult to install it indoors. The problem remains. Firstly, in the case of incineration treatment, the equipment must have a structure capable of withstanding high temperatures in order to perform this treatment, extremely high durability and safety are required, and there is a danger in installing it indoors. Secondly, in the case of dry treatment without incineration, it is difficult to deodorize the odor and a large amount of gas temporarily generated from the garbage during heat treatment, especially under high humidity. This may occur.

[0007] As described above, the garbage treating machine using the heating means is actually installed outdoors, and the garbage generated in the kitchen or the like has to be transported outdoors. is there. Further, when such a garbage processing machine is intentionally installed indoors, an exhaust system is indispensable, and it becomes a large-scale facility device, resulting in high cost and extremely poor usability.

The present invention is intended to solve the problem of such a conventional garbage disposal machine, and provides a convenient garbage disposal machine which can be installed indoors and does not generate a bad odor during processing with a simple structure. The primary purpose is to provide. A second object is to provide a kitchen waste processing machine capable of reliably processing odors.

[0009]

[Means for Solving the Problems] A first means of the present invention for achieving the first object is to provide a garbage container for storing garbage, a heating source for heating the garbage, and a heating source for generating the garbage during heating. A heat exchanger that exchanges heat with the exhaust gas to condense water, a drain container that stores condensed water provided downstream of this heat exchanger and that does not allow gas to permeate, and a gas that overflows downstream of the heat exchanger. And a gas-impermeable buffer container that temporarily stores the waste.

A second means of the present invention for attaining the second object is a garbage disposal device equipped with a deodorizing device between the heat exchanger and the buffer container in addition to the constitution of the first means. Is.

[0011]

According to the first means of the present invention, the exhaust gas generated from the garbage when the garbage is dried is cooled by the heat exchanger to store water in the expandable drain container, and the gas content is expandable and odorless buffer. It acts as a temporary storage in the container, and is capable of drying the kitchen waste in a closed system.

The second means of the present invention is that the deodorizing device provided between the heat exchanger and the shrinkable buffer container acts to reduce the odor concentration in the device, and the odor of the waste itself can be reduced. Is.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the first means of the present invention will be described below with reference to FIG. Reference numeral 1 is a garbage container that stores the garbage 2, and 3 is a rotary blade that stirs the garbage 2 provided in the garbage container 1. Further, 4 is a heat insulating container, which has a double wall having a vacuum between the walls. A heat exchanger 6 heat-exchanges the gas generated from the kitchen waste 2 during heating to condense water. The outer side of the heat exchanger 6 is the outer container 5, which is cooled by the cooling fan 14. Due to the above, the main body 27
It is what constitutes. Reference numeral 11 denotes a lid that covers the main body 27 so as to be openable and closable, and is attached to the main body 27 via packing 12 and lock 13 so as to prevent odors and the like from escaping.
A corrosion-resistant sheathed heater, which is a heating source 7 for heating the kitchen waste 2, and a fan 8 for sending hot air from the heating source 7 are provided above the main body 27. 9 is a motor of the fan 8. Further, reference numeral 10 is a reflecting plate which reflects the radiant heat of the heating source 7, and also serves as a mounting plate for mounting the heating source 7 and the fan 8. The rotary blade 3 is a motor 1 provided outside the main body 27.
5 is driven by a drive shaft 16.

Reference numeral 17 denotes a drain container for storing condensed water 18 cooled and condensed by the heat exchanger 6, and a part of the drain container 17 is a bellows tube 19 made of a stretchable resin. Drain container 17
Is made of polyester or fluororesin that does not allow gas to permeate, and is detachably attached to the heat exchanger 6 side through the joint 20, and the lower portion of the drain container 17 is detachably provided on the fixed plate 21. ing. The fixed plate 21 is provided with a rack 22, and a gear 23 driven by a drive motor 24 is engaged with the rack 22 to expand and contract the drain container 17. Also drain container 1
7 is connected to the main body 27 via a joint 20 provided with packing so that odor is not dissipated from the drain container 17. An exhaust pipe 25 guides the gas in the exhaust gas to the buffer container 26. The buffer container 26 is a thin bag having a thickness of, for example, 100 μm or less so that it can be easily expanded and contracted, and is made of polyester or fluororesin that hardly transmits odor. Similarly, the exhaust pipe 25 is also made of gas impermeable stainless steel or fluororesin. That is, the entire device is a closed system.

In the present embodiment, the volume of the garbage container 1 is about 6 liters, and about 1 kg of garbage can be stored. The volume of the buffer container 26 is about 10 liters when it is fully inflated.

The operation of this embodiment will be described below. About 1 kg of kitchen waste 2 containing fish, meat, vegetables, skins of fruits, seasonings and the like is put in the garbage container 1, the lid 11 is closed, and the operation of the apparatus is started. When the operation is started, the cooling fan 1
4. The rotary blade 3 and the fan 8 are driven, and at the same time, the heating source 7 is energized. In the present embodiment, the energization of the heating source 7 is controlled so that the temperature of the hot air is about 130 ° C. above the dust container 1. When this hot air is sent to the waste container 1 by the fan 8, the kitchen waste 2 contained therein is heated and dried, and the air in the waste container 1 expands and overflows from the waste container 1. While the exhaust gas passes through the heat exchanger 6, the water content is cooled and condensed by the cooling fan 14 and drops into the drain container 17. Further, the gas containing odor inflates the buffer container 26 and stays there. The expansion of the air in the waste container 1 occurs during the temperature rise of about 10 minutes, and the amount of gas discharged is about 8.2 liters. When the temperature inside the waste container 1 rises to some extent and stabilizes, the amount of gas discharged is only vaporized water vapor and odorous components, and becomes small. In addition, in this embodiment, the kitchen waste 2 loaded in the garbage container 1
Although about 95% of the water contained in the product is dried is the end point of the drying, the amount of water discharged during this period is about 750 g. When the drying is completed, the heating is stopped, and the cooling is started, the air in the waste container 1 starts to shrink. Therefore, the air in the buffer container 26 is drawn toward the dust container 1.
In this embodiment, heating of the kitchen waste 2 is started by the heating source 7, and at the same time, the drive motor 24 is operated in accordance with the amount of condensed water generated to inflate the bellows tube 19.

When the processing of the kitchen waste 2 is completed in this way, the joint 20 and the fixing plate 21 of the drain container 17 are removed, and the condensed water 18 is discarded to the drain port of the sink or the like. Condensed water 1
When the disposal of No. 8 is completed, the joint 20 and the fixing plate 21 are set again, and the bellows tube 19 is pushed back to the original contracted state by the drive motor 24 to prepare for the next process. At the end of the processing of the kitchen waste 2, the kitchen waste 2 is pulverized and dried and discarded as it is.

As described above, according to this embodiment, it is possible to prevent the odor from leaking to the outside of the apparatus while the garbage 2 is being processed, without providing a special deodorizing apparatus. Further, since the drain container 17 is inflated by the amount of the condensed water 18 generated, the air containing the malodor does not remain in the buffer container 26. Further, as for disposal, it is sufficient to remove the drain container 17 and dispose of the condensed water 18, so that the kitchen waste processing machine can be very easy to use.

Next, an embodiment of the second means of the present invention will be described with reference to FIG. In this embodiment, the exhaust pipe 25
A deodorizing device 27 is provided in the middle of. The deodorizing device 27 includes a suction fan or pump and a deodorizing element. As the deodorizing element, either a physical adsorbent such as activated carbon or a disposable one such as a chemical reaction agent, or a long-life catalytic deodorizing element such as an ozone generator and a catalyst, an ultraviolet source and a catalyst, a heating source and a catalyst is used. It is good to do.

The operation of this embodiment will be described below. When the temperature in the waste container 1 rises to a certain degree and stabilizes, the kitchen waste 2 is stirred by the rotary blade 3 and comes into contact with the inner surface of the waste container 1 to evaporate the moisture and expand the air in the waste container 1 to buffer it. The exhaust to the container 26 increases instantaneously. However, this vapor condenses when it leaves the waste container 1 and reaches the heat exchanger 6, so that the air on the side of the waste container 1 contracts. Therefore, the air in the buffer container 26 is sucked toward the dust container 1. Due to the expansion and contraction of these airs, the exhaust gas accompanied by the bad smell passes through the deodorizing device 27 many times. Thus, the odorous components contained in the gas are repeatedly deodorized, and the odor is reduced.

As described above, according to this embodiment, the deodorizing device 2
By providing 7, it is possible to deodorize high-concentration malodorous components, suppress the diffusion of malodorous substances at the time of dumping waste after finishing the drying treatment of kitchen waste 2, and lower the odor concentration in the device. Therefore, the odor of the kitchen waste 2 itself can be reduced.
