Abstract

PROBLEM TO BE SOLVED: To reduce an electricity cost, to suppress the temp. rise at the peripheral of a treating machine and to lessen the dispersion of smells by heating the air in a treating vessel housing garbage in a circulating route communicating with the inside of the treating vessel, introducing this air again into the treating vessel and reutilizing the air. SOLUTION: The air heated by a heating section is introduced by a blasting section 5 into the treating vessel 1, by which the garbage in the treating vessel 1 is subjected to a drying treatment. The waste gases of high temp. after the drying treatment that are heretofore discharged outside are introduced into the circulating route 2 disposed in a treating machine body 7. Steam is removed by a condensing section 4 in this circulating route and is deodorized in a deodorizing section. After the deodorized air is heated in a heating section, the air is introduced again into the treating vessel 1, by which sufficient reutilization of the waste heat of the waste gases is made possible. Consequently, the hot air of a desired temp. may be obtd. with a low electric power. The electricity cost is remarkably reduced. Even more, the dispersion of the smells to the outside is lessened.

[0001]

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

[0002]

2. Description of the Related Art Conventionally, a dry type garbage disposer has been used to dry garbage such as garbage to reduce the volume and weight of the garbage. As a drying type garbage processing machine, there is a garbage processing machine that dries garbage by supplying heated air into a processing tank.

A garbage processing machine using such hot air is:
Conventionally, air is constantly sucked in from outside during the drying process, heated by a heater, and then heated air is supplied into the processing tank to dry the garbage, then deodorized through an oxidation catalyst, and then exhausted to the outside. . As an example of such a kitchen waste processing machine, for example, a kitchen waste processing machine described in Japanese Patent Application Laid-Open No. 7-294139 introduces outside air into the kitchen waste container from the center of the lid, and removes the odor generated from the kitchen waste by the drying process. The exhaust gas containing high heat is discharged outside through a catalyst device.

[0004] However, the above-mentioned conventional garbage processing machine has a problem that a large amount of electricity is required because the air must always be heated from the outside temperature to about 100 ° C by a heater. In addition, there is a problem that the temperature around the processing machine tends to increase due to the high-temperature exhaust gas constantly discharged. In addition, there is a problem that the odor that has not been deodorized to the outside is dispersed together with the exhaust gas.

The present invention has been made to solve such a problem, and provides a garbage disposer that requires less electricity, can suppress a rise in temperature around the disposer, and has less odor dispersion. The purpose is to:

[0006]

According to the present invention, there is provided a garbage processing machine,
The air inside the processing tank containing the kitchen garbage is heated by a circulation path communicating with the inside of the processing tank and is again introduced into the processing tank, whereby the air is circulated inside the processing machine body, and the inside of the processing tank is The air that has expanded during heating is discharged to the outside, and the air in the processing tank that contracts after heating is sucked into the processing tank from the outside.

The garbage processing machine is provided with (a) the processing tank for storing the garbage, and (b) provided outside the processing tank.
Said circulation path in which both the upstream opening and the downstream opening communicate with the inside of the processing tank; and (c) provided in the circulation path.
A heating unit for heating the air inside the processing tank,
(D) a condensing section provided in the circulation path for condensing water vapor contained in the air inside the processing tank;
The circulation path is provided with a blowing unit for blowing air inside the processing tank into the circulation path, and the circulation path includes a portion expanded by heating the air inside the processing tank during heating. A communication hole is formed to discharge the air outside the processing tank and shrink the air in the processing tank after heating to the inside of the processing tank from the outside. In the circulation path, the upstream opening, the condensing section, and the blowing section are provided from the upstream side. , A heating section, a communication hole, and a downstream opening are preferably arranged in this order.

It is preferable that the communication hole has a diameter of about 2 to 10 mm.

[0009] It is preferable that a deodorizing section for deodorizing air in the processing tank is provided in the circulation path.

[0010] It is preferable that the deodorizing section is disposed upstream of the heating section.

In the circulation path, a check valve is provided between the communication hole and the downstream opening to prevent air from flowing back from the inside of the processing tank through the downstream opening to the communication hole. Preferably.

The garbage disposer of the present invention is an unprecedented energy-saving garbage disposer in which high-temperature exhaust gas is circulated inside the main body of the disposer. That is, by heating the air inside the processing tank in the circulation path provided inside the processing machine main body and introducing the air again into the processing tank, the residual heat of the exhaust gas can be sufficiently used. As a result, the power consumption of the heating unit such as a heater is reduced, so that the electricity cost is reduced as compared with the related art. Moreover, in the kitchen waste treatment machine of the present invention, since exhaust gas is hardly discharged to the outside, there is almost no dispersion of heat and odor to the outside.

When the pressure inside the processing tank increases during heating, the expansion of the air inside the processing tank is discharged to the outside through a communication hole formed in a circulation path, and conversely, after the heating, the processing tank is heated. When the internal pressure drops,
Since the shrinkage of the air inside the processing tank is sucked into the processing tank from outside, the pressure inside the processing tank can be smoothly adjusted.

[0015] The garbage disposal machine of the present invention heats the air in the processing tank for storing garbage such as garbage in a circulation path communicating with the inside of the processing tank and introduces the air into the processing tank again. Basically, the garbage is heated by circulating the air inside the treatment tank internally without constantly inhaling the outside air.

However, in order to adjust the pressure inside the processing tank,
The expansion of the air inside the processing tank during heating is discharged to the outside mainly through the communication holes and the like, while the air inside the processing tank contracted after heating is sucked into the processing tank from the outside. The amount of air flowing into and out of the treatment tank due to these pressure adjustments is small as compared with the intake amount or exhaust amount of the conventional kitchen waste treatment machine.

Hereinafter, a kitchen waste disposal machine of the present invention will be described with reference to embodiments.

Embodiment 1 A kitchen waste processing machine shown in FIGS. 1 to 4 is provided with a processing tank 1 for storing kitchen waste and an upstream opening 2 provided outside the processing tank 1.
a and the downstream side opening 2 b are both composed of a circulation path 2 communicating with the inside of the processing tank 1, and a heating section 3, a condensation section 4 and a blowing section 5 provided in the circulation path 2.
Further, a communication hole 6 for pressure adjustment is formed in the circulation path 2. In the circulation path 2, from the upstream side, the upstream opening 2a, the condensing section 4, the blowing section 5, the heating section 3, the communication hole 6, and the downstream opening 2b are arranged in this order. During the drying process, the flow of air inside the normal circulation path 2 flows in the direction shown by the arrows in FIGS. The circulation path 2 is provided with a check valve 10 and a deodorizing section 11.

The processing tank 1 is detachably mounted inside the drying chamber 8 of the processing machine body 7. The upper part of the drying chamber 8 has a lid 9
The inside of the drying chamber 8 can be kept airtight by a packing 8a. The material of the processing tank 1 is
It is preferable to use stainless steel which is hard to corrode or a material coated with polytetrafluoroethylene so as to prevent dust from sticking.

The condensing section 4 is for condensing water vapor contained in the air inside the processing tank 1 and forcibly blowing air to the radiator pipe 4a bent in a U-shape and the radiator pipe 4a. A cooling fan 4b for performing cooling, a drainage tank 4c for storing water condensed in the radiator pipe 4a, and a condensate for preventing air from flowing into the drainage tank 4c from the radiator pipe 4a. And a U-shaped trap 4d for storing a portion of the trapped water. The drainage tank 4c is provided with a handle 4e so that it can be easily pulled out of the processing unit body 7. Water vapor is cooled inside the radiator pipe 4a to become water droplets D, and the water droplets D are stored in the drainage tank 4c by natural fall.

The air blower 5 blows the air inside the processing tank 1 into the circulation path 2, and as shown in FIG. 3, the air inside the processing tank 1 passes through the pre-circulation path 2. Circulate clockwise. The blower 5 is provided with the condenser 4
The reason that it is arranged at the position between the heating unit 3 and
At that position, the temperature is the lowest in the circulation path 2 and it is possible to prevent the temperature of the blower 5 from rising.

As the heating unit 3, a conventionally used heater such as a sheathed heater formed in a coil shape is used. The air inside the processing tank 1 is heated when it is introduced into the circulation path 2 and passes through the heating unit 3 to become hot air.

The communication hole 6 is formed between the heating part 3 and the processing tank 1 in the circulation path 2 in order to adjust the pressure inside the processing tank 1.

The size of the communication hole 6 is preferably such that the air inside the circulation path 2 does not excessively escape to the outside, and can appropriately cope with expansion or contraction of the air inside the processing tank 1. About 2 to 10 mm, preferably 3 to 5 m
It is preferably set to about m.

The garbage disposal machine configured as described above introduces the air heated by the heating unit 3 into the processing tank 1 by the blowing unit 5 to dry the garbage in the processing tank 1. Then, the high-heat exhaust gas after the drying process, which has been conventionally exhausted to the outside, is introduced into the circulation path 2 provided inside the processing machine main body 7, and in the circulation path 2,
The remaining heat of the exhaust gas can be sufficiently utilized by removing the water vapor by the condensing unit 4, deodorizing by the deodorizing unit 11, heating by the heating unit 3 and then introducing again into the processing tank. As a result, hot air at a desired temperature can be obtained with low electric power, and the electricity cost can be extremely small.

Moreover, the communication hole 6 allows the processing tank 1
As for the air inside, the portion expanded during heating is discharged to the outside, and after the heating, the temperature inside the processing tank 1 is cooled and contracted, and the air is sucked into the processing tank 1 from outside. Therefore, the pressure inside the processing tank 1 during and after heating can be adjusted to be substantially constant.

In the above-mentioned kitchen waste treatment machine, the amount of air which is expanded outside is reduced, so that the amount of air which escapes from the treatment machine is extremely small.
Therefore, the temperature rise outside the processing machine is small, and the dispersion of odor is also small.

The circulation path 2 includes the processing tank 1
Since the deodorizing unit 11 for deodorizing the air sent from the air is provided, the air flowing through the circulation path 2 can be deodorized.
As the deodorizing section 11, one in which a conventionally used adsorbent such as activated carbon is accommodated in a container is used.

If the deodorizing section 11 is disposed on the upstream side of the heating section 3, the deodorizing section 11 can deodorize the air before heating the air, thereby preventing the adhesion efficiency from lowering.

Conventionally used adsorbents such as activated carbon generally have significantly reduced adsorption performance as the temperature of the introduced air increases. Therefore, the deodorizing section 11 may be disposed between the blowing section 5 and the heating section 3 in a section having a low temperature in the processing tank 1 and the circulation path 2.

Further, in the circulation path 2, between the communication hole 6 and the downstream opening 2b, backflow of air from inside the processing tank 1 to the communication hole 6 through the downstream opening 2b is prevented. Check valve 10 is provided.
The backflow prevention valve 10 is swingably provided so as to open only when air flows into the processing tank 1 through the downstream opening 2b, and is closed by its own weight when there is no air flow.

During or after the drying of the garbage, when the air inside the processing tank 1 expands and the air flows backward from the inside of the processing tank 1 to the communication hole 6, the valve 10 protrudes into the circulation path 2. And abuts against the closed valve wall 10a (see FIG. 4). For this reason, the air inside the processing tank 1 is temporarily discharged to the outside, but the amount is small and deodorized by the deodorizing section 11. Therefore, the odor that actually goes out can be reduced.

Further, when the check valve 10 is closed, a detecting means (not shown) detects it and turns off the heating section 3 to lower the temperature of the air flowing out of the communication hole 6. Therefore, the temperature rise around the processing machine can be further suppressed.

As shown in FIG. 1, when the pressure inside the processing tank 1 rises rapidly due to the ignition of ethyl alcohol contained in the garbage or the like, the air inside the processing tank 1 is released to the outside. If 12 is provided on the lid 9, it is safe.

Further, as shown in FIG.
In order to improve the drying efficiency by stirring the garbage inside, a stirring unit 13 having a stirring blade 13a and a stirring motor 13b for rotating the stirring blade 13a may be provided.

Embodiment 2 As another embodiment of the present invention, there is a kitchen waste treatment machine shown in FIGS. This kitchen garbage processing machine is shown in FIGS.
Instead of the communication hole 6 of FIG. 4, an intake hole 14 and an exhaust hole 15 having a check valve are formed, and the deodorizing section 11 is provided on the downstream side of the exhaust hole 15; The configuration is common with the garbage processing machine of FIGS.

The check valve 16 for suction provided in the suction hole 14 formed in the lid 9 is closed at the time of stop and at the time of the drying process, but after the drying process, the air inside the processing tank 1 is cooled and contracted. Only occasionally, the processing tank 1 is opened so as to introduce air from the outside into the processing tank 1.

The exhaust check valve 17 provided in the exhaust hole 15 formed at a position between the blower 5 and the heater 3 in the circulation path 2 is closed when stopped, but is closed during drying. Only when the temperature inside the circulation path 2 becomes high and the air inside the processing tank 1 expands, the circulation path 2 is opened to discharge air to the outside. Moreover, since the deodorizing section 11 containing activated carbon or the like is provided on the downstream side of the exhaust hole 15, air passing through the exhaust hole 15 is exhausted to the outside after being deodorized. In addition, a check valve 10 is provided between the processing tank 1 and the heating unit 3, and the exhaust hole 15 is provided in the heating unit 3.
The air heated by the heating unit 3 does not go outside through the exhaust hole 15 because it is disposed on the upstream side of.

The garbage processing machine shown in FIGS. 5 to 7 configured as described above is similar to the garbage processing machine shown in FIGS.
Since the air is circulated inside the processing machine body 7, the electricity cost is small, the temperature around the processing machine does not rise, and the odor is hardly dispersed.

When the drying process is completed and the lid 9 is opened, a detecting means (not shown) detects that the check valve 10 is forcibly closed and the blower unit 5 is turned on. The odor inside 1 and the circulation path 2 can be released after being deodorized via the deodorizing section 11, so that when the lid 9 is opened, the odor can be prevented from flowing out.

Embodiment 3 As still another embodiment of the present invention, FIGS.
There is a kitchen waste treatment machine shown in FIG. This kitchen waste processing machine
In place of the communication hole 6 in FIGS. 1 to 4, a flow path switching valve 18 capable of sucking outside air is provided, and the check valve 17 is provided.
An exhaust hole 15 provided with a catalyst heater 19 and a catalyst 20 such as platinum are provided together with the deodorizing section 11 on the downstream side of the exhaust hole 15. The configuration is the same as that of a kitchen waste disposal machine.

The kitchen waste treatment machine shown in FIGS. 8 to 10 utilizes the property that the deodorizing agent such as activated carbon in the deodorizing section 11 has a high adsorption performance and releases the adsorbed odor when the temperature becomes high. It has made recycling possible.
A specific recycling method will be described later.

During the drying process, the flow path switching valve 18 is closed between the outside and the circulation path 2, and the blowing section 5 and the heating section 3 are closed.
Open between. After the drying process, the space between the outside and the circulation path 2 is opened, and the space between the blower unit 5 and the heating unit 3 is closed.

The garbage disposer constructed as described above and shown in FIGS. 8 to 10 circulates air inside the treatment machine main body 7 like the garbage disposer shown in FIGS. The temperature around the processing machine does not rise, and there is almost no odor dispersion.

According to the kitchen garbage processing machine shown in FIGS. 8 to 10, during the drying process, the flow path switching valve 18 is closed between the outside and the circulation path 2, and the blowing section 5 and the heating section 3 are closed. The air is circulated inside the processing tank 1 and the circulation path 2 because the air is open between. At this time, the catalyst heater 19 is
In the FF state, the catalyst 20 does not perform the deodorizing function.

When the temperature inside the circulation path 2 becomes high and the air inside the processing tank 1 expands, the exhaust check valve 17 opens, and the air passes through the exhaust hole 15 from the circulation path 2 and is discharged by the deodorizing section 11. It is deodorized and is discharged outside through the non-functional catalyst heater 19 and catalyst 20. When the pressure inside the processing tank 1 falls below a predetermined pressure, the exhaust check valve 17 is closed by the force of the spring.

After the drying process, the deodorizing section 11 is subjected to a deodorizing process. First, the flow path switching valve 18 opens the space between the outside and the circulation path 2 and closes the space between the blower unit 5 and the heating unit 3. Also, the heating unit 3 and the blowing unit 5 of the circulation path 2 are turned on.
Then, the catalyst heater 19 is turned on and the cooling fan 4b is turned off. The temperature of the heating unit 3 is set higher than that of a normal drying process so that the odor is desorbed from activated carbon or the like during the deodorizing process. As a result, air is introduced into the circulation path 2 from the outside through the flow path switching valve 18, the introduced air is heated by the heating unit 3, and the residual odor of the processed garbage is removed through the processing tank 1. The air enters the deodorizing section 11 through the blowing section 5. The high-temperature air that has entered the deodorizing section 11 desorbs the odor adsorbed by the deodorizing section 11. Next, the odor contained in the air is decomposed by the catalyst 20 heated by the catalyst heater 19 and finally exhausted to the outside.

By the above deodorizing treatment, the treatment tank 1
The residual odor of the kitchen waste inside is removed, and the deodorizing section 11 can be recycled. Since the deodorizing treatment time is about one hour and has a deodorizing effect, the running cost can be reduced as compared with the case where the catalyst 20 is continuously heated during the normal drying processing time. Further, since there is little air going out, it is possible to suppress the temperature around the processing machine from becoming high, and the odor is less dispersed. Furthermore, since the deodorizing agent such as the activated carbon of the deodorizing section 11 is also recycled,
Can be used without replacement of deodorant.

[0049]

According to the present invention, the electricity cost can be reduced by reusing the residual heat of the exhaust gas. In addition, since the exhaust gas is circulated inside the main body of the processing machine, a rise in the temperature around the processing machine can be suppressed, and the odor to the outside is less dispersed.
