Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a food garbage disposal apparatus,

The present invention relates to a food garbage disposal apparatus capable of preventing reverse flow of sewage.

Food waste is one of the factors that pollute the environment. Research and development of various types of food garbage disposal devices for eco-friendly treatment of such food garbage is underway.

The food waste disposal system can be roughly classified into a drying method of drying and treating the cut and shredded food waste, and a fermentation method of fermenting the cut and shredded food waste while keeping the garbage for a certain period of time. In a home where a relatively small amount of food waste is discharged, a dry type food garbage disposal apparatus is mainly used.

Among the food garbage disposal apparatuses used at home, the food garbage disposal apparatus installed integrally with the sink, or installed in the inside of the sink, has a drain pipe connected directly to the sewage observation side, and the steam containing odor generated when the food garbage is dried is discharged to the sewage pipe side Respectively. That is, the discharge portion of the food garbage disposal apparatus for discharging the steam containing odor generated when the food garbage is dried is configured to communicate with the sewage observation side.

Therefore, in the conventional food garbage disposal apparatus, water in the sewage observation side can be introduced into the food garbage disposal apparatus when water in the sewage observation side flows backward to the sink side. In addition, when the sewage observation is blocked, water discharged from the sink to the sewer pipe or water discharged from the food garbage disposal device to the sewage pipe can be introduced into the food garbage disposal apparatus. Then, there is a disadvantage that the food garbage disposal apparatus may be damaged.

Prior art relating to a garbage disposal apparatus capable of preventing sewage backflow is disclosed in Korean Patent Registration No. 10-0839332.

It is an object of the present invention to provide a food garbage disposal apparatus capable of preventing backflow of sewage water which can solve all the problems of the conventional art as described above.

It is another object of the present invention to provide a food garbage disposing device capable of preventing backflow of sewage water that can prevent water from flowing back into the inside of the food garbage disposal apparatus, . ≪ / RTI >

According to an aspect of the present invention, there is provided a food waste disposal apparatus capable of preventing reverse flow of sewage water according to the present invention, comprising: a drying drum in which charged food waste is dried; A cooling pipe communicating with one side of the drying drum on one side and condensing when steam generated when the food garbage is dried; A trap which communicates with the other end side of the cooling pipe to receive the condensed water condensed in the cooling pipe and the remaining steam not condensed and discharges the received condensed water to the sewage pipe side; A guide tube communicating with one side of the trap at one side and communicating with the other side of the drying drum at the other side and guiding the non-condensing remaining steam received in the trap into the drying drum; And a valve for opening and closing a portion of the trap communicated with the other side of the cooling pipe and a portion of the trap communicated with one side of the guide pipe when the water in the sewage observation side flows into the trap side, .

When the water in the sewage observation side flows backward to one side of the trap, the valve is moved up and down and communicated with the other end side of the cooling pipe and the one end side of the guide pipe, The trapped portion of the trap is simultaneously closed. The backflowed water can not flow into the other side of the trap. Therefore, the water in the sewage observation is prevented from flowing into the inside of the food waste disposal apparatus, so that it is possible to prevent the food waste disposal apparatus from being damaged by the reverse flow of sewage.

In addition, a part of the odor generated when the food garbage is dried is discharged to the side of the sewage pipe, and the remainder flows into the drying drum side. That is, the odor generated when the food garbage is dried is not discharged to the outside of the food garbage disposal apparatus, so there is no need for a separate filter for removing odors. Therefore, the cost is reduced and the environmental pollution is prevented.

In addition, since the steam containing the odor reintroduced into the drying drum is a dry steam containing relatively little moisture, the moisture of the food waste can be quickly absorbed. Therefore, the drying efficiency is improved.

When the connection holder 121 is coupled to the cleaning cylinder, the central portion of the support plate 123 is contactably supported by the lower surface of the cleaning cylinder.

A buffer / horizontal (not shown) for adjusting the level of the casing 110 with respect to the sink is provided between the upper surface of the casing 110 and the support plate 123 to buffer vibrations of the garbage disposal apparatus, Adjusting means 125 may be provided.

A cutting / breaking unit (not shown) for cutting / breaking the food waste introduced into the connection holder 121 through the drain hole of the washing tub may be provided on the inner rear surface of the casing 110, A dehydrating unit (not shown) may be installed to receive dehydrated food waste that has been cut and shredded.

The dewatering unit includes a drain (not shown), and the drain of the dewatering unit discharges the water discharged from the food waste to a trap 160, which will be described later.

The configuration of the cutting / crushing unit and the dewatering unit may be the same as or similar to the configuration of the food garbage disposal apparatus disclosed in Korean Patent Registration No. 10-1104573 filed and filed by the applicant of the present invention. The dehydrating unit can dehydrate the food waste using the centrifugal force, and can discharge the dehydrated food waste using the centrifugal force.

The food waste can be discharged to the outside through the portion having the largest centrifugal force of the dehydration unit, and the food waste discharged from the dehydration unit can be put into the drying drum 141 and dried.

The upper surface of the drying drum 141 may be provided with an inlet port 141a through which the dehydrated food waste flows in the dehydrating unit and the inlet port 141a may be opened and closed by an opening and closing member 143 rotatably installed. When the inlet 141a is opened by the opening and closing member 143, the food waste discharged from the dewatering unit flows into the inlet 141a and into the drying drum 141.

A discharge port (not shown) through which dried food waste is discharged may be formed on the lower surface of the drying drum 141, and the discharge port of the drying drum 141 may be opened and closed by an opening and closing member (not shown). A heater (not shown) such as a heater, hot air or microwave may be installed on the outer surface of the drying drum 141 or inside the drying drum 141 to heat the food waste.

When drying the food waste inside the drying drum 141, a stirring screw (not shown) for stirring the food waste may be rotatably installed inside the drying drum 141. The stirring screw agitates the food waste to improve the drying efficiency, and at the same time, the food waste which is stuck to each other and stiff like a stump is crushed.

When food waste is dried, odorous steam is generated. However, when the steam containing odor is discharged to the outside, the user may feel uncomfortable and pollute the environment.

The food garbage disposal apparatus according to the present embodiment condenses the odor-containing steam generated during the drying of the food garbage and discharges the steam to the sewage pipe side. A portion of the remaining steam that is not condensed is discharged to the sewage pipe side, 141). ≪ / RTI >

The other end of the cooling pipe 151 is connected to one side of the inside of the trap 160 and the other end of the cooling pipe 151 is connected to the other end of the cooling pipe 151. [ . Between the trap 160 and the drying drum 141, one end side communicates with the inner side of the trap 160, and the other end side with a guide pipe 153 communicated with the other side of the drying drum 141 have.

One side of the inside of the trap 160 can communicate with the sewage observation side.

The steam flowing into the cooling pipe 151 flows along the cooling pipe 151 and exchanges heat with the atmosphere. Accordingly, some of the steam introduced into the cooling pipe 151 can be naturally cooled and then introduced into the trap as condensed water, while the remainder are not cooled and flow into the trap 160 at a relatively low temperature .

Then, the condensed water flowing into the trap 160 is discharged to the sewage pipe side. Some of the steam that has become relatively low temperature may be discharged to the sewage pipe side, and the remainder may be re-introduced into the drying drum 141 through the guide pipe 153.

Therefore, in the food garbage disposal apparatus according to the present embodiment, the odor is discharged to the sewage pipe side together with the condensed water and the steam, and the odor is re-introduced into the drying drum 141 together with the steam.

Since the steam re-flowing into the drying drum 141 through the guide pipe 153 is a dry steam containing relatively little moisture, the moisture of the food waste put into the drying drum 141 can be absorbed quickly. Therefore, the drying efficiency is improved.

The steam inside the drying drum 141 is forcedly cooled in one side of the cooling pipe 151 adjacent to the drying drum 141 so that the steam of the drying drum 141 can flow into the cooling pipe 151 more quickly And a fan 155 for sucking in the pipe 151 may be installed.

The trap 160 of the food garbage disposal apparatus according to the present embodiment will be described with reference to Figs. 4 to 6. Fig. FIG. 4 is an exploded perspective view of the trap shown in FIG. 2, FIG. 5 is a bottom perspective view of FIG. 4, and FIG. 6 is a schematic cross-sectional view of the trap shown in FIG.

As shown in the figure, the trap 160 may include a tubular body 161 having a space formed therein. The body 161 may include a case 162 having an opened upper surface and an upper surface And a cover 163 coupled to the upper end surface.

A partition member 168 may be provided in the interior of the case 162 inside the body 161 to divide the interior upper portion of the body 161. The upper surface and side surfaces of the partition member 168 are in contact with the side surfaces of the cover 163 and the case 162 respectively and the lower end surface of the partition member 168 is separated from the lower surface of the case 162.

The upper surface of the body 161 means the cover 163 and the lower surface and the side surface of the body 161 correspond to the lower surface and the side surface of the case 162, Of course.

The inside of the body 161 on the right side of the partition member 168 communicates with the other side of the cooling pipe 151, one side of the guide pipe 153 and the sewage observation side. One side of the cooling pipe 151 and one side of the guide pipe 153 are connected to the inner side of the body 161 through the first communication hole 161a and the second communication hole 161b formed on the upper surface of the body 161 And the sewage pipe side communicates with the inner right side portion of the body 161 through the third communication hole 161c formed on the side surface of the body 161. [ At this time, the third communication hole 161c is formed on the side surface of the body 161 positioned between the lower end surface and the upper end surface of the partition member 168. [ That is, the third communication hole 161c is formed higher than the lower end surface of the partition member 168. [

A fourth communicating hole 161d and a fifth communicating hole 161e communicating with the drain hole side of the dehydrating unit and the exhaust hole side of the flushing bowl are provided at a portion of the body 161 on the left side of the partition member 168 Respectively.

When water flows into the body 161 of the trap 160 from the dewatering unit or the cleaning cylinder, the water is submerged in the lower portion of the partition member 168. Thereafter, when water and condensed water continue to flow and the water level in the body 161 rises above the third communication hole 161c communicating with the sewage observation side, the water is discharged to the sewage pipe side.

The lower portion of the partition member 168 is immersed in water. The odor generated in the sewage observation by the partition member 168 and the water can flow into the inside of the body 161 on the right side of the partition member 168. However, It does not flow into the interior of the container. Also, the malodor introduced through the cooling pipe 151 can not enter the inside of the body 161 on the left side of the partition member 168. Therefore, the odor generated in the sewage observation and the odor introduced through the cooling pipe 151 may flow into the drying drum 141 through the guide pipe 153, It can not flow into the discharge hole of the cylinder.

Therefore, the odor generated in the sewage observation and the odor generated in drying the food waste are not leaked to the outside of the food garbage disposal apparatus according to the present embodiment at all. This eliminates the need for a separate filter to remove the odor generated when drying the food waste and the odor generated in the sewage observation, thereby reducing the cost and environmental pollution.

Even if the water of the sewage water flows backward, the water can flow into the body 161 on the right side of the partition member 168 but not into the body 160 on the left side of the partition member 168 . Therefore, the water of the sewage observation is prevented from flowing into the drain hole side of the dehydration unit and the exhaust hole side of the flushing bucket.

The water in the sewage observation side flows into the cooling pipe 151 and the guide pipe 153 when the water in the sewage observation side flows back to the trap 160 due to flooding or the like because the trap 160 is in communication with the sewage observation side, To the inside of the drying drum 141. In addition, when the sewage observation is blocked, water discharged from the dehydrating unit or the sink to the sewage pipe can be introduced into the drying drum 141 through the cooling pipe 151 and the guide pipe 153.

When the water in the sewage observation side flows back into the trap 160, the food garbage disposal apparatus according to the present embodiment is provided with a trap (not shown) communicating with the other end of the cooling pipe 151 and one end side of the guide pipe 153, The first communication hole 161a and the second communication hole 161b which are the portions of the drainage hole 160 are closed at the same time to prevent the water on the sewage observation side from flowing into the drying drum 141 side.

In detail, a valve 170 for opening and closing the first communication hole 161a and the second communication hole 161b may be installed in the inner left portion of the body 161. [ The valve 170 is supported on the upper surface of the body 161 at one side of the upper surface of the valve body 170 and rotatably mounted on the body 161. The valve 170 is connected to the first communication hole 161a communicating with the other side of the cooling pipe 151 and the one side of the guide pipe 153 while rotating and lifting according to the water level inside the body 161 And opens and closes the second communication hole 161b.

The valve 170 may be formed as a hollow body so that the valve 170 can be easily rotated and lifted according to the water level inside the body 161.

The upper surface of the valve 170 is opened so that the valve 170 can firmly close the first communication hole 161a and the second communication hole 161b and the upper end surface of the opened valve 170 is opened, Can be in close contact with the upper surface of the body 161 while covering the outside of the first communication hole 161a and the second communication hole 161b. The first communicating hole 161a and the second communicating hole 161b can be further sealed since the upper surface of the valve 70 is more closely adhered to the upper surface of the body 161 when the water level of the body 161 rises .

A sealing member 172 for sealing the first communication hole 161a and the second communication hole 161b more tightly may be provided on the opened upper end surface of the valve 170. [

A pair of support bars 165 facing each other may be formed on the upper surface of the body 161. A pair of support pieces 174 opposed to each other may be formed on the upper end side of the valve 170. A support hole 174a through which the support bar 165 is inserted may be formed in the support piece 174 have. The support piece 174 is rotatably mounted with respect to the support bar 165 to allow the valve 170 to rotate with respect to the upper surface of the body 161.

When the water in the sewage observation side flows backward into the trap 160, the valve 170 is lifted and rotated while the other end of the cooling pipe 151 and one end of the guide pipe 153 The first communication hole 161a and the second communication hole 161b, which are the portions of the trap 160 communicated with the second side, are simultaneously closed. Therefore, the water of the sewage observation is prevented from flowing into the drying drum 141 side. Since the backflowed water can not flow into the other side of the body 161, it is prevented from flowing into the dewatering unit and the washing tub.

Reference numeral 127 in FIG. 1 denotes a stopper for opening and closing the connection holder 121 exposed above the sink, and the stopper 121 may also function as a switch for turning the food waste disposal apparatus on and off. 1 is a food garbage bin for storing food waste discharged through the discharge port of the drying drum 141.
