The present invention relates to a food waste disposal device, and more particularly, to a deodorization device for deodorizing the odor gas of the food waste disposal device.

In general, the food waste disposal device is a device for processing the leftovers and the leftovers generated in kitchens such as homes and restaurants. As the water enters the water, the food waste disposal is stopped, and the demand is increasing day by day. In line with this, companies that manufacture food waste are also increasing in hunger.

Food waste (hereinafter referred to as "banban") is treated by various methods such as drying method, fermentation method, fermentation extinction method, dry fermentation method.

The drying method is simply a method of evaporating the moisture contained in the residue by applying heat to the collected residue through hot air or a heater. The fermentation method is a method of fermenting the residue using microorganisms, and the fermentation and extinction method is a The other compounding agent is used to ferment and dissipate more than 95% of the residue, and the dry fermentation method is to promote the powdered state of the evaporated residue by allowing some fermentation to occur during the water evaporation process.

Referring to the drawings will be described the structure of the food waste disposal system using the prior art drying method.

Referring to FIG. 1, the conventional food waste processor is provided with an outer tub 11 inside the main body 10, and a treatment tank 12 is installed to accommodate the remaining inside of the outer tub.

A stirrer 13 is rotatably provided below the processing tank 12, and a motor device 14 for rotating the stirrer is provided below the stirrer.

In addition, a heater device 15 is installed at an upper portion of the treatment tank 12 to generate a heat source for drying garbage, and a blower fan 16 is installed at an upper portion of the heater device 15 to blow heat to the remaining area. Let's do it.

One side of the outer tank 11 is provided with a condensation fan 20 for condensing the heated gas, the lower portion of the outer tank 11 is provided with a storage container 30 for storing condensed water.

At this time, a condensed water flow pipe 31 for guiding the condensed water condensed on the inner surface of the outer tank 11 to the storage container 30 is installed.

In addition, the main body 10 is provided with an exhaust duct 40 for guiding the odor gas discharged from the treatment tank 12 to the outside.

A deodorizing heater 41 is installed on the exhaust duct 40 to primarily deodorize the odor gas by heating it to a high temperature. At the rear side of the deodorization heater 41, the odor gas heated to a high temperature is deodorized using a platinum catalyst. Deodorizing portion 42 is installed horizontally with respect to the direction in which the odor gas flows.

At this time, an odor gas flow pipe 43 is installed between the condensate flow pipe 31 and the exhaust duct 40 to guide the odor gas generated in the treatment tank to the exhaust duct 40.

Referring to the operation of the waste disposal device configured as described above are as follows.

When the remaining power is put into the processing tank 12 and power is applied to the processing tank 12, the power is transferred to the stirrer 13 through the motor device 14, and the remaining table accommodated in the processing tank 12 as the stirrer 13 is rotated. Is stirred and mixed evenly.

In addition, when power is applied to the heater device 15 and the blowing fan 16 is rotated, hot air is supplied to the remaining table by the blowing fan 16 to generate moisture or gas contained in the remaining table. As the blower fan 16 is rotated, the hot air moves downward as shown by the arrow of FIG. 1 to dry the residue.

Water vapor generated in this process is converted into condensed water by the condensation fan 20 on the inner side of the outer tank (11).

The condensate is collected in the lower part of the outer tank 11 and stored in the condensate storage container through the condensate flow pipe 31, and then discarded to the outside.

In addition, the odor gas is flowed to the exhaust duct 40 through the odor gas flow pipe 43, and then heated to a high temperature by the deodorizing heater 41.

Thereafter, the odor gas heated to a high temperature is deodorized by the platinum catalyst component of the deodorizing unit 42 to change to a clean air state, and then discharged to the outside.

However, the food waste disposal system as described above has the following problems.

First, the structure of the deodorizing unit 42 for deodorizing the conventional odor gas is, as shown in Figures 2 and 3, a plurality of deodorizing pipe 42c is laminated with the inlet / outlet 42a, 42b is open And form the installed form.

As a result, the odor gas has a short time for passing through the deodorizing pipe 42c of the deodorizing unit 42 and has a small contact area, thereby preventing sufficient chemical reaction with the platinum catalyst component, thereby degrading deodorizing performance.

Second, according to the conventional structure, a separate deodorizing heater 41 and a deodorizing unit 42 for heating the odor gas to a high temperature in order to deodorize the odor gas had to be installed.

Accordingly, the exhaust duct 40 has a problem in that the structure is complicated and the installation cost is also high.

The present invention is to solve the above problems, an object of the present invention is to provide a food waste processor to improve the deodorizing portion structure of the food waste treatment, to improve the deodorizing performance of the odor gas.

In order to achieve the above object, the present invention is a treatment tank that accommodates the remaining, and the inside of the mixing stirrer for mixing the remaining evenly; An exhaust duct for discharging the odor gas generated in the treatment tank to the outside; It provides a food waste processor characterized in that it comprises a deodorizing unit having at least one planar heating element which is installed horizontally on the exhaust duct to the direction in which the odor gas flows to deodorize the odor gas. .

Here, the planar heating element is composed of a heating wire to which power is supplied, and a leading film formed to cover the heating wire.

Each planar heating element is formed in a wave structure consisting of a protrusion and a recess.

Therefore, there is no need to provide a separate deodorizing heater for deodorization, the odor gas is heated and deodorized at the same time while passing through the deodorizing portion to improve the deodorizing performance.

In addition, the flow path resistance received by the odor gas by the protrusions and the recesses during the passage of each planar heating element is increased, so that the time for chemical reaction with the platinum catalyst component is long, and the contact area is increased, resulting in an improved deodorizing performance.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention that can specifically realize the above object will be described.

The same components as in the prior art are given the same names and the same reference numerals for convenience of description, and thus the detailed description thereof will be omitted.
