Description

Deodorization for food waste treating apparatus {Deodorization for food waste treating apparatus}

The present invention relates to a deodorizing device for a food waste disposer, and more particularly, to a deodorizing device for a food waste disposer capable of deodorizing and removing odors generated in the process of treating food waste in the food waste disposer.

Recently, ocean dumping and direct landfilling of food wastes generated daily are prohibited to prevent environmental pollution, and unlike general wastes, they are collected separately and transported to a separate facility for treatment.

For this reason, food waste costs much more to treat than general waste, and food waste tends to increase every year with population growth and improvement in living standards, resulting in huge economic losses.

In order to prevent such economic loss, it is necessary to reduce the generation of food waste. The most effective method is to directly process the food waste that is inevitably generated along with self-rescue efforts to reduce the generation of food waste in each household, which is the main source. It is best not to leave the house as much as possible.

For reference, in Korea, the total treatment cost for food waste increased from about 600 billion won in 2005 to about 800 billion won in 2010. is currently doing.

In response, the government announced a resource circulation policy in 2013 to gradually ban landfilling of recycled resources, including food waste. The use of a processor is recommended.

There are various food waste disposers that can be used in general households, and can be classified into a drying method, a crushing method, a crushing/drying method, and a fermentation extinction method according to the treatment method. Household food waste disposers also have a stand-alone type and a sink drain pipe connection type depending on the installation type. The so-called sink drain pipe connection type is generally preferred over the stand-alone type in that it is convenient to use, invisible, and does not take up a separate space.

As an example of such a food waste disposer, a 'food waste fermentation extinguisher' has been proposed in Republic of Korea Utility Model Registration No. 20-0351640 (hereinafter referred to as 'prior art document').

In this prior art document, for the purpose of providing a food waste fermentation extinguisher capable of biochemically decomposing and extinguishing microorganisms and food waste in an extinguishing chamber for processing food waste, an exhaust duct is provided on one side of the gas to process the extinction process. It discharges odor and gas generated from the outside, and the dissipator is configured as a built-in type so that it can be installed indoors, such as a kitchen, where food waste is mainly generated, so that the kitchen space can be utilized and aesthetically pleasing. In order to achieve rapid decomposition, it is possible to increase the extinction rate of garbage by heating means and agitation, thereby solving the hassle of blocking food waste from households and separate collection of food, and creating a secondary environment due to landfill and incineration. Disclosed is a garbage fermentation extinguisher that prevents contamination (water/air pollution), has a simple structure, is easy to manufacture, and has increased use and failure due to low production cost.

However, in the prior art literature, since the odor generated in the stirring barrel is discharged to the outside using an exhaust duct, it is difficult to install the exhaust duct when installing the fermentation extinguisher in a windowless room, so there are restrictions on the installation place or environment. However, there are disadvantages such as the possibility of contaminating the indoor air by odor leaked from the exhaust duct.
