Description

Domestic food processor deodorizer

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a food waste disposal apparatus, and more particularly, to a food waste disposal apparatus for heating, stirring, And more particularly, to a deodorization apparatus for a domestic food processing apparatus.

Generally, a certain amount of waste (food waste) is discharged daily from each family or restaurant, and this residue is used as livestock feed as it is, or it is filtered after only the mixed water is filtered through a simple sieve. Such a disposal method increases the amount of garbage collected, and when the garbage is not frequently discarded, a malodor is generated to pollute the surrounding air, and thus a food processor is used.

1, an inlet door 12 for inserting a residue and a discharge door (not shown) for discharging the processed residue are formed outside the body of the food processor made of a heat insulating material, A deodorizing device for removing odors generated in the residual process, and the like are installed.

An agitator (16) is rotatably mounted in the treatment tank (11) to induce the composting of the residue while mixing the residual fermenting agent and the residue. The agitator 16 is installed outside the treatment tank 11 and is rotated by a driving force by a deceleration motor device 13 composed of a reduction gear train and a motor.

On the other hand, a fan heater device composed of a suction fan 14 for sucking outside air and a heater (not shown) installed to heat the air sucked by the suction fan 14 quickly removes the moisture in the residue, .

At this time, the deodorizing device is installed on the upper part of the food processor, and removes not only the odor in the steam generated by the operation of the fan heater but also the odor generated in the fermentation process of the residue. This water vapor is again condensed in a cooling device (not shown) and discharged to the outside.

In addition, the deceleration motor device, the fan heater device, etc. connected to the stirrer 16 are connected to the control panel 18 controlled by the microcomputer, so that the operation of the food processor can be controlled by a predetermined program. The control panel 18 may include a timer to sequentially control the operation of the food processor according to the set time and to receive the input of the temperature sensor provided inside the drying vessel, And may control the operation of the processor.

Such a conventional food processor disposes of the odor continuously generated during the reduction of moisture and the fermentation loss while heating and stirring the residue in the treatment tank 11, and the deodorizer processes and discharges the odor. However, using only a solid deodorant such as activated carbon There is a disadvantage that complete deodorization can not be expected in the conventional system.

Further, in order to more complete deodorization treatment, a deodorizing pipe of a relatively long distance is provided and a liquid type deodorizing method of supplying tap water is used. However, since the deodorizing pipe is long and is installed outside, additional work is required to install it.

In addition, there is a disadvantage in that the water is completely drained every time when the residue is composted and deodorized, or the water is discharged without being circulated.

Particularly, although the household food processor does not require a large amount of waste treatment as compared with the commercial use, it is installed under a relatively clean outdoor condition in a narrow space.

Accordingly, it is an object of the present invention to provide a food waste disposer for heating, stirring, deodorizing and discharging waste residue, So that it can be used for home use.

[Example]

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

FIG. 1 is a perspective view schematically showing a configuration of a food processor according to the present invention.

The food waste disposer of the present invention is provided with an inlet door 12 and a discharge door (not shown) on the outside and has a treatment tank 11, a suction fan 14, an exhaust fan 15, a control panel 18, an exhaust duct (not shown), and the like.

It is also the same in that the residue introduced into the dosing door 12 has a deodorizing function in which the moisture is reduced in the treatment tank 11 and the fermentation is reduced and the residue is composted to remove odors.

However, in the present invention, the deodorizing duct (19) is installed at the upper part inside the food processor. The deodorizing duct 19 replaces a kind of exhaust duct function, and is a tubular structure formed by bending an iron plate. The intake pipe 24 and the exhaust pipe 25 are respectively connected to pipes at both ends of the deodorizing duct 19 and the air introduced by the suction fan 14 is mixed with the odor and then exhausted from the intake pipe 24 to the exhaust pipe 25).

The ozone generator 20, the solid deodorant 17, the exhaust fan 15, and the like are sequentially installed in the deodorizing duct 19 from the intake pipe 24 side toward the exhaust pipe 25 side.

The ozone generator 20 is a means for primarily treating odors generated during the treatment of the residue, and ozone (O ₃ ) is generated as described later to achieve the desired purpose.

The solid deodorant 17 installed on the downstream side of the ozone generator 20 uses porous activated carbon. Porosity of activated carbon plays an important role in improving the purification ability by increasing the contact area when the odor passes through. However, if it is too fine, the flow resistance of the air increases and the power consumption is increased.

The exhaust fan 15 installed on the downstream side of the solid deodorant 17 functions to send the purified air to the exhaust pipe 25. The flow of the air inside the food processing apparatus is mainly received by the suction fan 14 and the exhaust fan 15 is miniaturized to ensure a sufficient space for installing the ozone generator 20 and the solid deodorant 17 relatively .

The exhaust pipe 25 is disposed so that one end thereof is guided to the lower end of the food processor. Considering that the food processor of the present invention is for domestic use, it is prevented that the ozone generator 20 and the solid type deodorant 17 are scattered far away even if there is air that has not been purified.

On the other hand, the control panel 18, which controls the water loss and the fermentation loss of the residue, operates the ozone generator 20 regardless of the throughput of the residue in the process of composting the residue, or only when the throughput of the residue exceeds the reference value, So that the deodorizing action can be carried out for the second time by operating the air conditioner 20.

FIG. 2 is a piping diagram showing the deodorizing device in detail in FIG. 1, and FIG. 3 is a block diagram of the ozone generator in FIG.

The ozone generator 20 includes a discharge plate 21 made of an insulating material having a small thickness and an electrode plate 22 bonded to both side surfaces of the discharge plate 21. The electrode plate 22 has a predetermined voltage And a high-voltage transformer 23 for applying a high-voltage power.

Such ozone generator 20 generates ozone by causing a discharge phenomenon (corona discharge) due to a high potential difference formed on both sides of the discharge plate 21, and the discharge air generated in food processing is decomposed by the decomposition force of ozone, The smell is removed because it is decomposed.

The air to be firstly purified by the ozone generator 20 is secondarily purified while passing through the solid deodorant 17, that is, the activated carbon layer, and then discharged to the outside in a clean air state. Activated carbon is effective for removing a relatively wide range of odors such as ammonia, ethylamine, manure, diethylamine, and garbage, and the replacement period is relatively long, such as 2-3 years.

As described above, since the flow of air in the food processor is mainly received by the suction fan 14, it is also possible to use a small-sized (for example, about 60 mm diameter) fan and a DC motor as the exhaust fan 15.

The operation according to the present invention will be described with reference to FIGS. 1 and 2.

Since the ozone generator 20 of the present invention consumes a relatively large amount of electric power, it is preferable that the ozone generator 20 is appropriately turned on and off rather than always on during the treatment of the food. The following two modes can be set.

First, when the user opens the inlet door 12 to turn on the power switch (not shown) in the control panel 18, the suction fan 14 and the heater operate for a predetermined time to remove moisture, So that the ozone generator 20 is operated for a predetermined time from the moment when the dosing door 12 is opened. Thereafter, the exhaust fan 15 is continuously operated to cause the purification treatment by the solid type deodorant 17 to occur.

This mode takes into account the fact that the offensive odor is most severely generated in the initial stage of opening the dosing door (12) to start the treatment, and the offensive odor is alleviated as the process is terminated.

Second, when the user turns on the power switch and turns on the power switch in the control panel 18, the suction fan 14 and the heater operate for a predetermined period of time to remove water and then agitate with the fermentation agent to compost, The ozone generator 20 is turned on and off. At this time, the exhaust fan 15 is continuously operated to cause the purification treatment by the solid type deodorant 17 to occur.

This mode is easily performed when the control panel 18 is constituted by a microcomputer circuit, and a fixed control method of turning on and off the ozone generator 20 at a constant cycle (for example, stopping for two minutes and five minutes) It is possible to shorten the ON time of the ozone generator 20 and increase the ON period of the ozone generator 20 from the initial stage to the completion stage.

Further, as another embodiment, by using a gas sensor (not shown) made of a ceramic material whose internal resistance value is changed by a predetermined gas component, it is possible to perform the function according to the present invention more efficiently than the above two modes Do.

That is, when the user turns on the power switch only in the control panel 18, the control panel 18 checks whether or not the gas sensor is input. At this time, while the odor concentration of a predetermined value or more is detected, the ozone generator 20 is operated to burn the odor component first, purify the odor component firstly by the solid type deodorant 17 behind it, 25).

As described above, the large food waste treatment device deodorization apparatus of the present invention can be applied to a large-sized food waste treatment device deodorization apparatus that does not require a separate piping device to be installed on the outside, by using an ozone generator in the inside of a food waste treatment device for heating, stirring, It is possible to completely remove the odor and use it for home use.

Although the present invention has been shown and described with respect to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as set forth in the following claims Those skilled in the art will readily understand the present invention.
