Abstract

PROBLEM TO BE SOLVED: To realize at low cost the constitution in which condensed water can be discharge while the sealed state is maintained. SOLUTION: Condensed water flows down in a downward flow passage 32 of a S-shaped pipe 31 and accumulates in a U-shaped part connecting an upward flow passage 33 to the downward flow passage 32. The accumulated water rises to a water level (a), thereby cutting off a flow passage by which gas is communicated from the downward flow passage 32 to the upward flow passage 33. Therefore, a space consisting of a heating chamber 13 and a fin tube 21 is made into the sealed state. Water continue to accumulate in the S-shaped pipe 31, however, since water in the upward flow passage 33 flows to a sewer 1 through a sewage flow passage 34 by the amount of water exceeding the water level (b), the water level is stabilized without the water continuing to increase.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposer for drying garbage such as garbage.

[0002]

2. Description of the Related Art Heretofore, there has been known a garbage disposer in which garbage such as garbage is dried to prevent decay and odor components generated during treatment are deodorized. Generally, such a garbage processing machine is configured to deodorize and discharge steam generated by heating garbage.

Since garbage is mainly generated in the kitchen, it is convenient to install a garbage disposal machine indoors.
There are many factors that deteriorate the indoor environment, such as leakage of odor, increase in humidity due to discharge of water vapor, and increase in temperature due to heat sources, and it has been difficult to install indoors. Therefore, the applicant of the present application forms a closed space by closing the on-off valve, heats the garbage in the closed space, condenses the generated water vapor in the condensing chamber, and discharges the condensed water to the sewage pipe to emit odor. Prevent leaks and humidity rise, and also prevent odor leakage by making the enclosed space negative pressure, and reduce the temperature rise due to heating,
An invention that can be used indoors has been previously proposed.

[0004]

However, in such a configuration, when the condensed water in the closed space increases, it is necessary to open and close the on-off valve every time the condensed water increases, so that the closed state can always be maintained. could not. In addition, using an on-off valve such as a solenoid valve increases the cost.
SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problem and to realize a configuration capable of discharging condensed water at a low cost while maintaining a sealed state.

[0005]

According to a first aspect of the present invention, there is provided a kitchen waste treatment machine for heating kitchen garbage such as garbage, the kitchen waste being generated from the kitchen garbage in communication with the heating unit. Forming a condensing section for cooling and condensing the water vapor, a drainage path for draining water condensed in the condensing section to the outside, and a condensed water reservoir for storing water in a flow path from the condensing section to the drainage path; In a state where the water accumulated in the water pool exceeds a predetermined sealed water level, the water shuts off a flow passage communicating the gas of the condensing portion and the gas of the drainage channel, and a predetermined drainage water level higher than the sealed water level. The gist of the present invention is that a drainage section for draining excess water into the drainage channel is provided.

[0006] According to a second aspect of the present invention, there is provided a kitchen waste processing machine according to the first aspect,
The cut-off drain section includes a down flow path through which water from the condensation section flows downward, an up flow path that temporarily rises from the down flow path, and a drain flow path that descends from the up flow path and connects to the drain path again. The gist of the present invention is that the structure is an S-shaped tube structure.

[0007] According to a third aspect of the present invention, there is provided a kitchen waste processing machine according to the first aspect,
The cut-off drain section includes a tank for storing water, a condensed water discharge pipe that hangs down from the bottom of the tank and allows water from the condensing section to flow downward, and water that exceeds a predetermined drain water level of the tank. And a drain pipe for draining water to the outside.

In the kitchen waste treatment machine according to the first aspect of the present invention having the above-described structure, a condensed water reservoir for storing water is formed in a flow path from the condensing section to the drainage passage, and the water accumulated in the condensed water reservoir is at a predetermined sealed water level. In the state that exceeds, the water shuts off the flow path that connects the gas in the condensation section and the gas in the drainage channel,
The communication space between the heating unit and the condensation unit is closed. Heating of the garbage and condensation of the generated water vapor are performed in the closed space to prevent the non-condensed water vapor from being directly discharged to the outside. In addition, the water condensed in the condensing section is sent to the condensed water pool, but the water accumulated in the condensed water pool is drained to the outside (for example, a sewer pipe) from a drainage channel when a predetermined drainage level is exceeded. Most of the odors generated from kitchen garbage are drained with water without ever increasing.

Further, the present invention has the above-mentioned structure.
In the above described garbage disposal machine, water from the condensing section accumulates in a portion connected from the down flow path to the up flow path, and when the amount of the accumulated water exceeds a predetermined amount, the flow path through which the gas communicates is shut off. Therefore, the communication space between the heating unit and the condensation unit can be sealed. Further, when the amount of water in the upflow channel increases, the water is drained to the outside through the drainage channel, and therefore does not continue to increase.

Further, the present invention has the above-mentioned structure.
In the described kitchen waste treatment machine, water from the condensing section flows to the tank via the condensed water discharge pipe. Further, when the amount of water accumulated in the tank exceeds a predetermined amount, the flow path communicating between the gas of the condensed water discharge pipe and the gas of the drain pipe is shut off. Therefore, the communication space between the heating unit and the condensation unit can be sealed. Further, the amount of water in the upstream flow passage exceeding the predetermined drainage water level is drained to the outside through the drainage pipe, and thus does not continue to increase.

BEST MODE FOR CARRYING OUT THE INVENTION In order to further clarify the structure and operation of the present invention described above, a preferred embodiment of a kitchen waste disposal machine of the present invention will be described below. FIG. 1 shows a first embodiment of the present invention.
It is a schematic structure figure of a kitchen garbage processing machine as an example. This garbage processing machine is roughly divided into a heating unit 10 for heating garbage,
A condensing unit 20 for condensing water vapor generated from garbage,
It comprises a blocking drainage section 30 for blocking the flow path for communicating the gas between the condenser section 20 and the sewer pipe 1 and for draining water.

The heating unit 10 includes a processing tank 1 for storing garbage.
1, a heater 12 for heating the processing tank 11, and a heating chamber 13 having a heat insulating structure for accommodating them. In addition, a lid 13a that opens and closes to put the processing tank 11 in and out is formed in an upper part of the heating chamber 13.

The condensing section 20 is composed of a fin tube 21 communicating with the upper part of the heating chamber 13 and a fan 22 for blowing air to the fin tube 21.

The cut-off drain section 30 communicates with the down flow path 32 through which water from the fin tube 21 flows downward, the up flow path 33 which rises once from the down flow path 32, and the down flow path 33 again from the up flow path 33 to the drain 1. Pipe 31 which forms a drain passage 34
It consists of.

Next, the operation of the kitchen waste disposal machine will be described. When garbage is put into the processing tank 11 and the drying operation is started, the heater 12 starts heating the processing tank 11. Therefore, the temperature in the processing tank 11 and the heating chamber 13 rises, the moisture contained in the garbage evaporates, and the air in the heating chamber 13 and the fin tube 21 is pushed out toward the sewer pipe 1 by steam. After a lapse of a predetermined time, the fan 22 is operated by the condensing unit 20 to blow air to the fin tube 21, thereby cooling and condensing the water vapor in the fin tube 21. The condensed water flows down the S-shaped pipe 31
2, the accumulated water rises to the water level a from the down flow path 32 to the up flow path 33 and accumulates at the U-shaped portion, so that the gas communicates from the down flow path 32 to the up flow path 33. Block the road. Therefore, the space formed by the heating chamber 13 and the fin tube 21 is in a closed state. And
When the amount of heat taken by the fin tubes 21 is equal to or more than the amount of heat given by the heating chamber 13, the pressure in the closed space is reduced as shown in the graph of FIG. Therefore, the inside of the heating chamber 13 becomes a negative pressure, the boiling point is lowered, the water can be evaporated at a low temperature, and the odor component can be hardly leaked to the outside. On the other hand, the fin tube 2
The hot air blown to 1 and subjected to heat exchange hits the outer wall of the heating chamber 13 and heats the outer wall to increase the heat retention efficiency of the heating chamber 13.

On the other hand, water accumulates in the S-shaped pipe 31, but the amount of water in the upward flow path 33 exceeding the water level “b” is
Since the water flows into the sewer pipe 1 through 4, the water level does not increase and the water level is stabilized. Further, since the water level difference between the downstream flow path 32 and the upstream flow path 33 is determined by the pressure difference between the inside of the closed space and the inside of the sewer pipe 1, the water level in the state where the pressure in the closed space has a negative pressure value Stabilizes at water level c higher than b. Most of the odor components generated from the garbage are S-shaped tubes 3
It dissolves in the water collected in 1 and is drained to the sewer pipe 1.

The pressure in the closed space is naturally adjusted by the S-shaped tube 31. For example, when the pressure in the closed space rises above the atmospheric pressure, the water level of the water in the down flow path 32 falls. Then, when the water drops to the water level a, FIG.
As shown in (a), the gas on the downstream flow path 32 side is
It is discharged to the 3 side. Therefore, the pressure in the closed space increases only up to a predetermined value determined by the water level difference between the up flow path 33 and the down flow path 32.

On the other hand, when the pressure in the closed space falls below the atmospheric pressure, the water level in the down flow path 32 rises, and the water level in the up flow path 33 falls. Then, when the water in the upflow channel 33 falls to the water level a, FIG.
As shown in (b), the gas on the upstream flow path 33 side is
It is inhaled to two sides. Therefore, the pressure in the closed space drops only to a predetermined value determined by the water level difference between the down flow path 32 and the up flow path 33.

As described above, according to the kitchen waste disposal apparatus of the first embodiment, the flow of gas from the down flow path 32 to the up flow path 33 is shut off by the water accumulated in the S-shaped pipe 31. Thus, the heating chamber 1 can be used without using an on-off valve such as a solenoid valve.
Since the communication space formed by the fin tube 3 and the fin tube 21 can be sealed, it can be configured at low cost. In addition, the amount of water in the upward flow path 33 exceeding the water level b is determined by the drainage flow path 3
Since the water flows into the sewer pipe 1 via the pipe 4, the water can be drained while maintaining the sealed state. Furthermore, since the pressure range in the closed space can be adjusted by the water level difference between the up flow path 33 and the down flow path 32, it is possible to prevent a decrease in heating efficiency and an odor leak due to a high pressure in the closed space. It is possible to prevent backflow of water into the heating chamber 13 due to low pressure. In addition, the cut-off drain section 30 is an S-shaped pipe 31
Since it can be constituted only by the above, it can be realized at low cost.

In addition, since the steam generated from the heated garbage is condensed and drained together with the odor, it is possible to prevent the odor from leaking and increase the humidity, thereby preventing the deterioration of the indoor environment. Furthermore, since the inside of the heating chamber 13 has a negative pressure, it is possible to prevent the odor from leaking from the gap with the lid 13a, so that it is not necessary to make the sealing performance excessively high. Since the treatment can be performed, energy required for heating can be reduced, power consumption can be reduced, and a rise in indoor temperature can be reduced. In addition, there is no need to provide an expensive device such as a vacuum pump in order to make the inside of the heating chamber 13 a negative pressure, and further, it is not necessary to provide a deodorizing device or a water vapor discharging device, so that the structure is simplified and the cost is reduced. be able to.

As shown in FIGS. 4A and 4B, S
By reducing the space below the pipe 31, the amount of water required from the start of the drying operation until the gas communication flow path is cut off may be reduced, thereby shortening the time required for the cutoff. Good. Further, a configuration in which the gas communication flow path is shut off while water is always stored may be employed.

Next, a second embodiment will be described. FIG.
FIG. 4 is a schematic configuration diagram of a kitchen waste treatment machine as a second embodiment of the present invention. Although the basic configuration is the same as the kitchen waste treatment machine of the first embodiment (FIG. 1), the configuration of the cut-off drain section is different. The same reference numerals are given to other overlapping portions, and description thereof will be omitted.

The cut-off drain section 40 includes a tank 41 for storing water.
And the fin tube 2 hanging down from the bottom of the tank 41
A condensed water discharge pipe 42 for flowing water from
A drain pipe 4 for communicating the upper side surface of the tank 1 with the drain pipe 1 and draining water that exceeds a predetermined water level d in the tank 41 to the drain pipe 1.
And 3.

The flow path for communicating the gas between the condensed water discharge pipe 42 and the drain pipe 43 is in a state where the level of the water accumulated in the tank 41 is higher than the lower end opening surface (water level f) of the condensed water discharge pipe 42. Will be shut off. Since the water in the tank 41 increases due to the water from the fin tubes 21 and exceeds the water level d, the water flows to the sewer pipe 1 via the drain pipe 43, so that the water level does not increase and the water level is stabilized. Further, since the water level difference between the condensed water discharge pipe 42 and the tank 41 is determined by the pressure difference between the inside of the closed space and the inside of the sewer pipe 1, when the pressure in the closed space is a negative pressure value, the water level is lower than the water level d. Stable at high water level e.

When the pressure in the closed space increases beyond the atmospheric pressure, the water level of the condensed water discharge pipe 42 decreases. Then, when descending to the water level f, the air on the condensed water discharge pipe 42 side is discharged to the tank 41 side as shown in FIG. Therefore, the pressure in the closed space increases only up to a predetermined value determined by the water level difference between the tank 41 and the condensed water discharge pipe 42.

On the other hand, when the pressure in the closed space falls below the atmospheric pressure, the water level of the condensed water discharge pipe 42 rises, and the water level of the tank 41 falls. Then, when the water in the tank 41 falls to the water level f, FIG.
As shown in (b), the air on the tank 41 side is sucked into the condensed water discharge pipe 42 side. Therefore, the pressure in the closed space drops only to a predetermined value determined by the water level difference between the condensed water discharge pipe 42 and the tank 41. That is, the pressure in the closed space can be naturally adjusted and maintained.

As described above, according to the garbage processing machine of the second embodiment, in addition to the effects of the first embodiment, in the event of a negative pressure, the water accumulated in the tank 41 is shut off until the water level drops to the water level f. In order to maintain the state, the heating chamber 13 of the condensed water discharge pipe 42
By increasing the height of the tank 41 in the vertical direction and increasing the capacity of the tank 41, the limit value on the negative pressure side can be set large regardless of the limit value on the positive pressure side. Therefore, it is possible to reduce the limit value on the positive pressure side and increase the limit value on the negative pressure side to easily maintain the pressure in the sealed space on the negative pressure side.

The embodiments of the present invention have been described above.
The present invention is not limited to these embodiments at all, and it goes without saying that the present invention can be implemented in various modes without departing from the gist of the present invention. For example, in the present embodiment, the fan 22
Was operated, but the invention is not limited to this. For example, the fin tube 2
The temperature, humidity, pressure, and the like in the inside 1 and the heating chamber 13 may be detected and operated based on the detected values, or may be operated simultaneously with the heater 12. The garbage is not limited to the configuration heated by the heater 12, but may be configured to be heated by a gas burner, a microwave, or the like.
Further, the condensing unit 20 is not limited to the configuration in which the cooling is performed by the fan 22, but may be configured to naturally radiate heat using, for example, a draft force. Further, in the present embodiment, the heating unit 10 and the condensing unit 20 are provided in separate rooms, but may be configured to be performed in the same room.
