Description

FOOD GARBAGE DISPOSER

Technical Field

[1] The present invention relates to a food garbage disposer, and more particularly, to a food garbage disposer wherein food garbage is decomposed within a treatment tank using a microorganism, and foul smell and harmful components residing in an exhaust gas produced during the decomposition process are diluted with external air and discharged to the outside. Background Art

[2] It is very difficult to bury and incinerate food garbage because the food garbage is moist and easily spoiled. Accordingly, a variety of treatment or disposal plans for reduction and recycling of food garbage have been discussed for a long time.

[3] As food garbage treatment technologies, a variety of disposal methods such as water removal, crush, drying, decomposition-by-fermentation, fermentation & drying, extinction and the like have been proposed. Among them, the extinction method is similar to the decomposition-by-fermentation method in which the food garbage is disposed of using an effective microorganism, in view of their operations. However, the extinction method is a method obtained by improving the fermentation method such that decomposition efficiency is enhanced and maximum reduction of food garbage is accomplished. Further, the decomposition method is particularly suitable for home use, because its time period of discharge for garbage remnants is once per four to six months.

[4] When reducing the quantity of the food garbage using a microorganism, it is apprehended that the exhaust gas produced during the decomposition process gives out a bad smell and contains the harmful components. Therefore, it is necessary to pay particular attention to the treatment of the exhaust gas.

[5] As a food garbage disposal technology for treating an exhaust gas, an organic substance treating device for simultaneously discharging an exhaust gas and external air by using an axial flow fan disposed on a vent is disclosed in Japanese Patent Laid- Open Publication No. 2001-025751 (Publication Date: January 30, 2001).

[6] However, since the aforementioned treating device is configured such that the axial flow fan causes the exhaust gas and external air to be sucked and discharged through the vent, there are problems in that a rate at which the exhaust gas is diluted is greatly reduced and the device is not suitable for home use due to larger vibration and noise produced by the axial flow fan.

[7] Furthermore, the aforementioned conventional treating device further comprises a deodorizing device that includes a deodorizing catalyst and a heater and has a function of diluting the exhaust gas. However, deodorizing efficiency of the deodorizing device is reduced since a time period when the exhaust gas is brought into contact with the deodorizing catalyst and heater is short. If the deodorizing efficiency is to be enhanced, the size of the deodorizing catalyst and heater should be inevitably increased and practical utility thereof is greatly reduced accordingly.

Disclosure of Invention Technical Solution

[8] Therefore, an object of the present invention is to provide a food garbage disposer that can sufficiently mix and dilute external air and exhaust gas with each other and discharge the mixed and diluted gas to the outside and that is configured to be particularly suitable for home use or commercial purpose due to quiet operation thereof for the dilution.

[9] Another object of the present invention is to provide a food garbage disposer wherein a combustion-type deodorizing device unit for deodorizing an exhaust gas through the combustion is further included, but efficiency of deodorizing the exhaust gas can be enhanced without any additional increase in the size of the deodorizing device unit.

[10] A further object of the present invention is to provide a food garbage disposer capable of performing the flushing deodorization and dilution for the exhaust gas at a low noise level.

[11] According to an aspect of the present invention for achieving the aforementioned objects, there is provided a food garbage disposer, comprising a treatment tank for decomposing and disposing of or treating food garbage with a microorganism; an exhaust pipe for causing an exhaust gas produced in the treatment tank to be discharged to the outside of the treatment tank; a dilution device unit which communicates with external air and the exhaust pipe at an upstream side thereof and includes a centrifugal fan disposed therein for receiving the exhaust gas and external air in an axial direction and blowing the received exhaust gas and external air in a radial direction; and a combustion-type deodorizing device unit provided between the treatment tank and the dilution device unit, said combustion-type deodorizing device unit including a deodorizing chamber communicating with the exhaust pipe, a heating element disposed in the deodorizing chamber for heating the exhaust gas, and a deodorizing catalyst for removing foul smell from the exhaust gas at a downstream side of the heating element, wherein the deodorizing chamber includes a neck portion that is positioned between the heating element and the deodorizing catalyst and has a reduced sectional area of a flow path. Therefore, the exhaust gas produced in the treatment tank can be sufficiently diluted and discharged to the outside.

[12] According to another aspect of the present invention, there is provided a food garbage disposer, comprising a treatment tank for decomposing and disposing of or treating food garbage with a microorganism; an exhaust pipe for causing an exhaust gas produced in the treatment tank to be discharged to the outside of the treatment tank; and a dilution device unit which communicates with external air at an upstream side thereof and is also connected with the exhaust pipe at a downstream side thereof, and includes a centrifugal fan for receiving the external air in an axial direction and blowing the received external air toward the downstream exhaust gas. Therefore, the exhaust gas produced in the treatment tank can be sufficiently diluted and discharged to the outside, and thus, the contamination of the dilution device unit due to the exhaust gas can also be reduced.

[13] Preferably, the food garbage disposer of the present invention further comprises a combustion-type deodorizing device unit provided between the treatment tank and the dilution device unit. At this time, the combustion-type deodorizing device unit includes a deodorizing chamber that communicates with the exhaust pipe, a heating element that is disposed in the deodorizing chamber to heat the exhaust gas, and a deodorizing catalyst for removing foul smell from the exhaust gas through a catalytic combustion reaction at a downstream side of the heating element.

[14] In particular, the heating element may be made of a conical coil that continuously converges from an upstream side to a downstream thereof and may generate heat when electrical power is applied thereto. Therefore, the exhaust gas in the treatment tank can be heated at a more uniform temperature.

[15] Preferably, the deodorizing chamber includes a neck portion that has a rapidly reduced sectional area of a flow path at a position between the heating element and the deodorizing catalyst. Here, the neck portion serves to enhance deodorization efficiency of the aforementioned deodorization device unit by retarding the flow of the exhaust gas in the deodorizing chamber.

[16] More preferably, the food garbage disposer of the present invention further comprises a flushing-type deodorization device unit that is installed on the exhaust pipe to absorb and remove foul smell discharged from the exhaust pipe using water.

[17] At this time, the flushing-type deodorization device unit preferably includes a reservoir in which water is stored and an exhaust gas discharge tube that is immersed in the water of the reservoir while connected to the exhaust pipe. Further, the exhaust gas discharge tube may be formed with a plurality of exhaust gas discharge holes on an outer circumference thereof, whereby the noise-free flushing-type deodorization can be obtained.

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

[26] Fig. 1 is a partially cut-away perspective view schematically showing a food garbage disposer, in a rear direction, according to a first embodiment of the present invention; Fig. 2 is a front sectional view of major components of the food garbage disposer shown in Fig. 1; Fig. 3 is a side sectional view of the major elements of the food garbage disposer shown in Figs. 2 and 3; and Fig. 4 is a schematic view illustrating an overall connection relationship of the food garbage disposer shown in Figs. 1 to 3.

[27] As shown in Figs. 1 to 4, a food garbage disposer 1 of the first embodiment of the present invention comprises a treatment tank 2, an exhaust pipe 3 through an exhaust gas is discharged from the treatment tank 2 to the outside, and deodorizing device unit 4 and 6 and a dilution device unit 5 which are connected to the exhaust pipe 3 to deodorize and dilute the exhaust gas, respectively, and the like.

[28] The treatment tank 2 is installed within a housing 7 that includes a main body 72 and a lid 74 to define an external appearance of the food garbage disposer, and has such an upwardly opened structure that the food garbage can be put into the treatment tank from above to below when the lid 74 is opened. An agitator 22 for agitating and mixing a microorganism and the food garbage with each other to accelerate the de- composition by microorganism is installed within the treatment tank 2 such that the agitator can be vertically turned by a driving motor 23a and a power transmission mechanism 23b. At this time, the agitator 22 includes an agitating shaft 22a connected via a shaft to the power transmission mechanism 23b, agitating rods 22b extending from the agitating shaft 22a in a direction perpendicular to the agitating shaft 22a, and agitating blades 22c formed at outer ends of the agitating rods 22b.

[29] Particularly, an automatic discharge portion 24 in the form of a hinge structure is formed on a front center region of the treatment tank 2 to automatically discharge the treated food garbage to the outside. The automatic discharge portion 24 allow the food garbage on the agitating blades 22c to be easily and automatically discharged to the outside of the treatment tank 2 even with the rotation of the agitator 22, because it is provided at a position where the food garbage falls from an inclined agitating blades due to a rotating centrifugal force of the agitator 22. At this time, the automatic discharge portion 24 is provided with a fastener, such as a bolt, at a lower end thereof such that the treatment tank 2 is kept to be in a closed state during the process of treating or disposing of the food garbage.

[30] Moreover, a manual discharge portion 25 is further provided at a position below the automatic discharge portion 24 to allow bolts to be unfastened and then the food garbage collected on the floor of the treatment tank 2 to be manually discharged to the outside. Further, a discharge door through the food garbage taken out through the automatic and manual discharge portions 24 and 25 is discharged to the outside of the housing 7 and a guide 724 in the form of an inclined plate by which the food garbage is guided to the discharge door 722 are provided on the aforementioned main body 72 of the housing.

[31] In the meantime, an exhaust gas produced in the treatment tank 2 is discharged to the outside of the treatment tank 2 through the exhaust pipe 3. The exhaust pipe 3 includes a variety of pipe parts for connection with the respective components for treating the exhaust gas and extends to a position adjacent to the outside of the food garbage disposer 1.

[32] In this embodiment, the exhaust gas produced in the treatment tank 2 first flows into a combustion-type deodorizing device unit 4. As shown in Figs. 3 and 4, the combustion-type deodorizing device unit 4 comprises a deodorizing chamber 42 that is in communication with the exhaust pipe 3, a heating element 44 that is placed in the deodorizing chamber 42 to generate heat when electrical power is applied thereto, and a deodorizing catalyst 46 provided at a downstream side of the heating element 44, in order to deodorize the exhaust gas through a catalytic combustion method.

[33] The heating element 44 generates heat at a temperature of about 200 to 350 ⁰C on the basis of a sensing signal of a temperature sensor 45 in the deodorizing chamber 42, and a combustion reaction between the deodorizing catalyst 46 and the exhaust gas can be accelerated through the heat generation. In particular, the heating element 44 is structured in the form of a conical coil that converges from an upstream side to a downstream side according to flow distribution of the exhaust gas in the deodorizing chamber 42, and such a conical coil structure can compensate for variation in a flow rate of the exhaust gas caused by the flow rate distribution f shown in Fig. 5 such that uniform and efficient heating on the exhaust gas can be made.

[34] In addition, as shown in Figs. 3 to 5, the deodorizing chamber is integrally formed with a neck portion 422 that is positioned between the heating element 44 and the deodorizing catalyst 46 and has a rapidly reduced sectional area of the flow path. The neck portion 422 causes to the flow of the exhaust gas in the deodorizing chamber 42 to be retarded and thus the exhaust gas to be brought into contact with the heating element 44 and the deodorizing catalyst 46 for a longer time, so that efficiency of deodorizing the exhaust gas can be enhanced.

[35] At this time, a catalyst obtained by adding nanosilver and/or noble metal such as platinum, cobalt and nickel to a honeycomb-type carrier made of aluminum oxide, silicon oxide, titanium oxide or ceramic. In particular, a deodorizing catalyst carried with nanosilver is most suitable in that the catalyst can perform the sterilizing and antibiotic functions against the germs and viruses in addition to the deodorizing function.

[36] Furthermore, the exhaust gas that has passed through the combustion-type deodorizing device unit 4 again flows in a dilution device unit 5 via the exhaust pipe. The dilution device unit 5 includes a diluting chamber 51 and a centrifugal fan 52 disposed with the diluting chamber 51. The diluting chamber 51 is in communication with the exhaust pipe 3 and external air A at an upstream side of the centrifugal fan 52 and connected with a vortex chamber 54, which will be described later, at a downstream side of the centrifugal fan 52. Therefore, the aforementioned centrifugal fan receives the exhaust gas and external air A in an axial direction at the upstream side and then sends the received exhaust gas and external air toward the downstream side in a radial direction, so that the exhaust gas and external air can be mixed with each other through the above process. At this time, the diluting chamber 51 of this embodiment may be provided with a filter 512 at an inlet side for the external air to remove dirt or dust in the external air.

[37] As described above, the dilution device unit 5 is configured such that it is installed directly on the exhaust pipe 3 and uses the centrifugal fan 52. Thus, a quiet operation of the food garbage disposer 1 can be performed, a dilution rate of the exhaust gas can be increased through direction change of the external air, and only a single centrifugal fan 52 can be used to control the exhaust gas and external air. [38] It is illustrated in the figures regarding this embodiment that the dilution device unit

5 is used together with the aforementioned combustion-type deodorizing device unit 4, and the vortex chamber 54 and a flushing-type deodorization device unit 6, which will be described later, but it may be used solely to dilute the exhaust gas and to discharge the diluted exhaust gas to the outside according to decomposition efficiency by microorganism in the treatment tank 2, dilution efficiency of the dilution device unit 5, installation condition of the food garbage disposer 1 and the like.

[39] According to the preferred embodiment of the present invention, the exhaust gas that has passed through the dilution device unit 5 passes again through the vortex chamber 54 with folds or helical grooves 542 formed on an inner surface thereof to help the external air to be mixed with the exhaust gas. The mixed gas of exhaust gas and external air in the form of vortex stream, which has passed through the vortex chamber 54, flows in the flushing-type deodorization device unit 6 through a downstream exhaust pipe 3.

[40] The flushing-type deodorization device unit 6 of the embodiment is a part in which the remaining foul smell and fine dirt and dust, which were not removed by the combustion-type deodorizing device unit 4, are absorbed in water and then removed, and is especially suitable for removing the hydrophilic foul smell such as ammonia, (low-class) amines, ketones, aldehydes, low-class organic acids, or phenols.

[41] The aforementioned flushing-type deodorization device unit 6 includes a reservoir

62 and an exhaust gas discharge tube 64 immersed in water of the reservoir 62. The exhaust gas discharge tube 64 is configured in such a manner that one end thereof is connected to the exhaust pipe 3, the other end thereof is closed, and a plurality of fine discharge holes 642 are formed on an outer circumference of the discharge tube.

[42] Therefore, the exhaust gas discharge tube 64 causes the exhaust gas to flow out into the water through the exhaust gas discharge holes 642 and the hydrophilic foul smell, such as ammonia, (low-class) amines, ketones, aldehydes, low-class organic acids, or phenols, to be absorbed with water and then to be removed. Particularly, since the plurality of exhaust gas discharge holes 642 allows the size of air bubbles and thus noise generated from the exhaust gas to be reduced, the problem of noise occurring in the flushing-type deodorization can be solved. At this time, a pressure pump 61 is preferably installed at an upstream side of the aforementioned flushing-type deodorization device unit 6 and provides the exhaust gas with a discharge force such that the exhaust gas can flow out into the water in the reservoir 62 by means of the large discharge pressure.

[43] In addition, the reservoir 62 is provided with a lid 63 at an upper end of thereof. The lid 63 is used to clean the reservoir 62 and to replenish the reservoir with water. Further, the lid 63 is configured to be formed with an exhaust holes 632 com- municating with the outside through an exhaust grille 77 of the housing 7 such that the exhaust gas collected in an upper portion of the reservoir can be discharged to the outside.

[44] Moreover, the aforementioned reservoir 62 is configured in such a manner that it is inclined and opened outwardly of the housing 7 for the easy replenishment of water into and cleaning of the reservoir. This configuration can be implemented by installing a reservoir support 76 (not shown in Fig. 1) to the housing 7 to be hingedly opened and closed and then loading the reservoir 62 on the reservoir support 76 in such a configuration as shown in Fig. 3. At this time, a portion of the exhaust pipe 3 extending into the flushing-type deodorization device unit 6 may be formed into a flexible tube in order to readily open the reservoir 62.

[45] Further, it can be understood from Fig. 3 that the aforementioned reservoir support

76 and exhaust grille 77 are integrally formed with each other, but the present invention is not limited thereto.

[46] Hereinafter, other embodiments of the present invention will be described with reference to Figs. 6 and 7. In describing the following embodiments, the contents that overlap those of the previous embodiment are omitted herein for the brevity of the descriptions, and like reference numerals are again used to designate like elements for performing the same functions as in the previous embodiment.

[47] Fig. 6 is a schematic view of a food garbage disposer 1 according to a second embodiment of the present invention. The food garbage disposer 1 according to this embodiment illustrated in Fig. 6 is configured to dilute the exhaust gas in the following manner. That is, the dilution device unit 5 is in communication with the external air at an upstream side of the centrifugal fan 52' and connected with an exhaust pipe 3 at a downstream side of the centrifugal fan 52' such that the aforementioned centrifugal fan 52' sucks up the external air in an axial direction and then forcibly sends the received external air toward the exhaust gas located at the end of a diluting chamber 51'.

[48] According to the dilution device unit 5' so configured, the quiet operation of the food garbage disposer 1 can be performed, and the dilution rate of the exhaust gas can be also increased through direction change of the external air. Particularly, since the flow of the exhaust gas in the diluting chamber 51' is excluded, the contamination of the centrifugal fan 52' and the diluting chamber 51' are prevented.

[49] Fig. 7 is a schematic view of a food garbage disposer according to a third embodiment of the present invention. The food garbage disposer 1 according to this embodiment illustrated in Fig. 7 is configured such that the exhaust gas is discharged to the outside just after it has passed through the dilution device unit 5 and a vortex chamber 54. Further, unlike the food garbage disposer of the previous embodiments of the present invention, the food garbage disposer 1 is configured such that the flushing- type deodorization for the exhaust gas is performed between the treatment tank 2 and the combustion-type deodorizing device unit 4.

[50] To this end, the aforementioned flushing-type deodorization device unit 6' includes a reservoir 62' and an exhaust gas discharge tube 64' immersed in water of the reservoir 62' The exhaust gas discharge tube 64 is connected to the upstream exhaust pipe 3, and the reservoir 62' is connected to the downstream exhaust pipe 3 located at an upper end thereof.

[51] Therefore, the exhaust gas discharge tube 64' causes the exhaust gas to flow out into the water through a plurality of exhaust gas discharge holes 642' and the exhaust gas that has been converted into air bubbles and then collected near the upper end of the reservoir 62' flows into the combustion-type deodorizing device unit 4, the dilution device unit 5 located at the downstream side of the combustion-type deodorizing device unit 4 and the vortex chamber 54 through the downstream exhaust pipe 3.

[52] In such a case, it can be understood from Fig. 7 that an air pump 32 for feeding the exhaust gas from the treatment tank 2 up to the exhaust gas discharge tube 64' is installed at the exhaust pipe 3 upstream of the exhaust gas discharge tube 64' At this time, a pressure pump for feeding the exhaust gas to the air pump 32 or increasing the pressure of the exhaust gas in a certain circumstance may be installed at the upstream side of the flushing-type deodorization device unit 6'.

[53] Here, the food garbage disposer 1 of this embodiment performs the flushing-type deodorization for the exhaust gas that has not yet been diluted unlike the food garbage disposer of the previous embodiments, it is obvious that the deodorization efficiency of this embodiment is superior to that of the previous embodiments.

[54] Although it has been described in the previous embodiments that the flushing-type deodorization device unit is selectively installed either at the upstream side of the combustion-type deodorizing device unit or at the end of the exhaust pipe, further enhanced efficiency of deodorizing the exhaust gas can be expected since the flushing- type deodorization device unit of this embodiment is installed both at the end of the exhaust pipe and at the upstream side of the combustion-type deodorizing device unit.

[55] Although the present invention has been illustrated and described in connection with the preferred embodiments, it can be understood that various modifications, changes and corrections can be made thereto without departing from the scope and spirit of the present invention. Accordingly, the foregoing descriptions and drawings should be construed not to limit the technical spirit of the present invention but to be illustrative of the present invention.As described above, since the device where the exhaust gas is mixed and diluted with the external air is improved in the food garbage disposer of the present invention, the efficiency of diluting the exhaust gas is enhanced and the noise generated due to the dilution of the exhaust gas is reduced accordingly. Therefore, there is an advantage in that the quiet operation of the food garbage disposer can be made.

[56] Further, the flow of the exhaust gas in the deodorization device is retarded and the exhaust gas is heated at a uniform temperature in the food garbage disposer with the combustion-type deodorizing device unit according to the present invention. Therefore, there is another advantage in that the deodorization efficiency of the deodorization device unit is increased.

[57] In addition, the flushing-type deodorization device unit is improved to produce fine air bubbles in the food garbage disposer with the flushing-type deodorization unit according to the present invention. Therefore, there is a further advantage in that low noise flushing-type deodorization can be performed.

[58] Moreover, the reservoir can be inclined and opened toward the outside of the housing according to the food garbage disposer with the flushing-type deodorization device unit. Therefore, there is a further advantage in that an operator can easily and conveniently perform various a variety of operations such as replenishment of water into the reservoir, and cleaning and exchange of the reservoir.
