Description

{APPARATUS FOR TREATING FOOD WASTE}

The present invention relates to a food waste disposal apparatus using hot air, and more particularly to a food waste disposal apparatus in which a deodorizing filter is dried and regenerated.

In general, a food waste disposer for drying and treating food waste uses a filter to discharge moisture generated during drying. The method of adsorbing only the odor component and releasing the wet vapor to the atmosphere is generally selected. Recently, there has been an increasing tendency to use the adsorption method of activated carbon filter to remove the restriction on the installation of the food garbage disposal apparatus, but there is still a problem in using the activated carbon for a long time. Therefore, in order to use the activated carbon filter for a long period of time, the detergent is loosened in water, washed and flowed, and the adsorbed component is released. After that, if dried and used well, its performance can be maintained over 80%.

FIG. 1 is a view showing a conventional food garbage disposer 100. FIG. As shown in the figure, the conventional food waste disposal apparatus 100 is provided with a reservoir 120 inside the housing 110. The housing 110 is formed with an intake port 131 and an exhaust passage 132. A hot air generating mechanism is installed inside the housing 110. The hot air generating mechanism includes a drying fan (not shown) and a heater (not shown). A filter 190 is connected to the exhaust passage 132. The display unit 180 displays the operation status of the processor 100. The food garbage is opened and closed by the door 181.

In the conventional food garbage disposer 100, when the door 181 is opened and food waste is supplied, hot air is generated through a hot air generating mechanism to dry the food waste, and the humid air generated at that time is discharged through the exhaust path 132. At this time, the activated carbon deodorization kit, which is the filter 190, adsorbs the odor.

However, the filter 190, which is an activated charcoal deodorization kit, is difficult to use for a long period of time. Currently, it is recommended to use the detergent after natural drying for 2 to 3 days after the cleaning if the adsorption saturates.

However, the dried and regenerated filter adsorbs the odor components around the room again during the normal storage, and its ability can be considerably reduced, and it is difficult to judge whether it is completely dried or not. Therefore, there is a high possibility that the performance will not be good when the regeneration filter is used again.

In addition, currently, the activated carbon filter is used in a cartridge, which makes it difficult to dry the water easily and to complete regeneration. At present, it is hard to say that even if dried for more than 2 days, it is practically dry enough.

An object of the present invention is to provide a food garbage disposer capable of self-drying and regenerating with a filter mounted thereon.

According to an aspect of the present invention, there is provided a food garbage disposer for drying food waste using hot air, comprising: a housing having a storage space for food waste therein, the housing having an inlet port and an exhaust path; A hot air generating mechanism disposed inside the housing to include a heater and a drying fan to generate hot air; An exhaust fan disposed in the exhaust passage; A filter detachably connected to the exhaust passage; A control unit for controlling operation of at least a hot air generating mechanism and an exhaust fan according to a set program; And an operation panel capable of inputting an instruction to the control unit, wherein the program set in the control unit further includes a step of controlling the operation of the exhaust fan and the hot air generating mechanism for drying the filter, so that the filter is connected to the exhaust passage In accordance with the program set for the filter drying. Preferably the filter is an activated carbon deodorization kit.

The program set for filter drying includes: (1) determining whether there is an instruction to dry the filter; (2) a primary drying step in which, when there is an instruction for drying the filter, the hot air generating mechanism and the exhaust fan are operated to provide hot air of T ° C for M hours to the filter connected to the exhaust path; And (3) a second drying step of stopping the operation of the hot air generating mechanism and operating only the exhaust fan. At this time, preferably, the M time is 2 to 3 hours, and the T ° C may be 50 to 70 ° C.

The display unit may further include a display unit for displaying an operation of the food waste disposal unit, and the display unit may display the progress of the steps (1) to (3).

The exhaust passage may further include an electron ion emitter mounted on a front portion of a connection position of the filter and the operation of which is controlled by a control unit. In this case, the control unit may further include the electron ion emitter controlling the ion release in the secondary drying step of the step (3).

As the effect of the present invention, the filter in use can be quickly regenerated and reused immediately, so that no extra activated carbon filter is required. It is also possible to ensure the performance by ensuring perfect drying. In addition, by operating the electron emitter for a certain period of time, the reproduction performance can be further improved. In the present invention, it is possible to reuse and reuse it without any inconvenience by drying it within about 5 hours. In addition, an electron emitter is placed on the front side of the filter to further improve the regeneration ability of the activated carbon, so that the filter can be used for a long period of time.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
