Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a configuration in which exhaust gas generated during fermentation in a fermenter for fermenting and decomposing garbage discharged from a home kitchen or the like is deodorized and exhausted.

[0002]

2. Description of the Related Art A conventional technique relating to a household garbage fermentation / decomposition processor is well known. A stirring claw shaft is laid on a fermenter serving as a container, and a claw is planted on the stirring claw shaft. When aerobic bacteria and moisture regulators that promote fermentation are added together with garbage through the inlet provided at the top of this fermenter, the garbage is crushed. While being stirred, it is decomposed by bacteria,
In addition, a technique for further decomposing the input garbage to completely dispose it has been known. The fermenter is provided with an intake port, an exhaust port, and the like, to take in oxygen necessary for fermentation of the contents in the fermenter, and exhaust air containing a large amount of exhaust gas and moisture generated by fermentation. Also, a technique has been known in which this exhaust gas is introduced into a deodorizing device made of a catalyst or the like to remove odor and exhaust the gas.

[0003]

However, as a technique for deodorizing exhaust gas generated from a fermenter in a conventional fermentation treatment machine, in a technique using a catalyst in a deodorizer, a honeycomb structure or the like is employed to increase the surface area. Therefore, clogging was likely to occur due to dust in the exhaust gas. Further, in a configuration in which a odor is adsorbed by using a thermal catalyst as a deodorizing device, it is necessary to increase the exhaust air temperature. However, if the exhaust gas flow rate is large, it is difficult to maintain the exhaust air temperature high, and the external air is not sufficiently decomposed without being sufficiently decomposed. Exhausting the air in the air would significantly damage the environment.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a garbage disposal machine for sucking and exhausting exhaust gas from a fermenter for fermenting and decomposing garbage using an exhaust means. An inlet pipe for guiding the exhaust gas to the deodorizer was provided between the fermenter and the deodorizer, and the inlet pipe was provided with an openable and closable exhaust port so that the exhaust port could directly exhaust to the outside. Further, an openable and closable lid is arranged above the exhaust port, and the lid is opened according to the amount of exhaust air. Further, the amount of air exhausted by the exhaust means can be increased or decreased in accordance with the intermittent drive of the stirring claw shaft, so that the amount of exhaust air is reduced during stirring and the amount of exhaust air is increased when stirring is stopped. Also, in a garbage disposer that sucks exhaust gas from a fermenter for fermenting and decomposing garbage through an exhaust unit and sends it to a deodorizer having a thermal catalyst to exhaust it, an exhaust pipe is connected to the outlet of the deodorizer. The outside air introduction means was connected to the exhaust pipe. The exhaust pipe was connected to the outlet of the deodorizing device at right angles to the outlet, and outside air introduction means was connected to one end of the exhaust pipe. In addition, a fermenter for fermenting and decomposing garbage is stored in a casing, the casing is placed on a deodorizing case, and both are communicated with each other. As an exhaust path that leads directly to the outside,
A deodorizing device is disposed in the other space to provide an exhaust path leading to the outside after deodorizing, and the two exhaust paths can be switched in the ventilation through a valve.

A motor 43 as a driving means of the stirring claw shaft 19 is provided in a space where the collection tray 29 is disposed between the casing bottom 10c and the lower part of the fermenter 1. That is, it is driven by the power of a motor 43 as a driving means screwed and fixed to the inner surface of the support stand 56 on the lower right side. The motor 43 is a motor that can be driven forward and reverse, and has an output shaft 43a of the motor 43.

FIG. 4 shows an embodiment in which a deodorizing device 62 is arranged, and a rectangular box-shaped deodorizing case 63 having a size substantially equal to the left and right and the depth of the garbage disposal 9 is attached to a lower portion of the casing 10. Legs 70, 70, 70 are formed in the lower corners of the deodorizing case 63. One of the four corners is provided with a screw leg 70 ', and the garbage disposal 9 is positioned horizontally. Is possible.

The deodorizing case 63 is formed in a box shape by a steel plate, and as shown in FIGS. 5 and 6, a plurality of vertically elongated air holes 63a are formed on the front and rear surfaces in pairs. Is provided. Also, the deodorizing case 63
A partition plate 75 is erected substantially in the front-rear direction from a front portion at a position closer to the right side of the center to a middle position in the rear, and the inside of the deodorizing case 63 is partitioned left and right. The deodorizing device 62 is disposed substantially diagonally in the deodorizing case 63 and is housed in the left space. The space on the right side inside the deodorizing case 63 is opened to serve as a flow path for exhaust air as described later.

A deodorizing introduction pipe 64 is provided at the rear of the deodorizing device 62.
Are communicated with each other, and as shown in FIGS.
The rear portion is bent upward, and its upper end is projected above the deodorizing case 63. The upper end of the deodorization introduction pipe 64 communicates with the exhaust pipe 23 projecting below the casing lower part 10c via a sealing member 71 such as sponge or rubber,
Just put the casing 10 on the deodorizing case 63,
Both can be communicated without using a connecting tool such as a bolt. Note that fixing pieces 73, 73, 73, 73 are erected at the corners of the upper surface of the deodorizing case 63, and the casing bottom 1
The garbage disposal machine 9 is securely fixed on the deodorizing case 63.

The lower part of the deodorizing introduction pipe 64 is located behind the partition plate 75 and is branched in two directions in different directions in the horizontal direction, one of which is directed substantially diagonally and connected to the deodorizing device 62. The exhaust pipe 64b has a large diameter and is directed forward. The exhaust pipe 64
b is located in the space on the right side divided by the partition plate 75.

A front end of the connection pipe 64a is connected to a case 66 accommodating a U-shaped heater 65 in a plan view, and a thermal catalyst 67 formed in a honeycomb shape is provided on the front side of the case 66.
Is arranged. The upper and lower surfaces of the case 66 are provided with concave portions 66a and 66b protruding toward the open portion of the U-shaped heater 65 so as to direct the flow of the exhaust air in the case 66 to the side.
The exhaust air is made to flow as much as possible along the U-shaped heater 65 so as to efficiently heat the air.

Further, a front end of the case 66 is communicated with a rear side surface of the exhaust pipe 76. The exhaust cylinder 76 has a rectangular cross section and is arranged orthogonal to the diagonal deodorizing device 62. An exhaust fan 77 as outside air introduction means is connected to the rear end of the exhaust pipe 76,
The front end of the exhaust pipe 76 is connected to the right side of the front of the deodorizing case 63 having the air holes 63a, 63a,.
6 is formed, and a flow path for exhausting air to the outside through the air holes 63a is formed. The exhaust air heated and deodorized by the deodorizing device 62 is changed in the exhaust pipe 76 in the exhaust tube 76. While mixing with the outside air, the mixture is stirred and cooled.

On the other hand, the front end of the exhaust pipe 64b, which is located in the space on the right side and is partitioned by the partition plate 75, is formed in a forward downward slope projecting forward from the upper part to the lower part. I am wearing it. The switching lid 78 is thin and lightweight, and the pivot pin 78a at the top of the switching lid 78 is connected to the exhaust pipe 64b.
When the amount of exhaust air in the deodorization introduction pipe 64 is large, the air is swung upward as indicated by a two-dot chain line in FIG. 8 and the end of the exhaust pipe 64b is opened to exhaust air. When the air volume is small, the deodorizing introduction pipe 64 is used as a switching valve so as to be turned downward and closed by its weight.

Further, an electric wiring port 79 is provided in the left and right central portion on the rear surface of the deodorizing case 63, and the exhaust fan 7 is provided.
7. A voltage is applied to the heater 65 and the thermal catalyst 67. These are controlled by the controller 80 so that the driving of the heater 65 and the exhaust fan 77 and the exhaust air volume of the exhaust fan 21 are synchronized with the intermittent drive of the stirring claw shaft 19.

More specifically, a motor 43 for driving the agitating claw shaft 19 is connected to the controller 80, and after being driven for a fixed time, stopped for a set time, and then reversely rotated for a fixed time thereafter. The controller 80 is controlled to intermittently drive the forward and reverse rotations by repeating the operation.

On the other hand, the heater 65, the thermal catalyst 67, and the exhaust fan 77 are also connected to the controller 80 via a drive circuit (not shown), and the drive of the motor 43 (the rotation of the stirring claw shaft 19) is started. The heater 65 and the thermal catalyst 67 are heated to drive the exhaust fan 77, and are turned off after a lapse of time Tb after the driving of the motor 43 is stopped.

The exhaust fan 2 as an exhaust means is provided.
The amount of exhaust air of 1 is controlled so as to increase or decrease in accordance with ON / OFF of the heater 65 and the heat catalyst 67 and the exhaust fan 77, that is, intermittent drive of the motor 43 (drive of the stirring claw shaft 19). As a configuration for adjusting the exhaust air volume,
This is performed by interposing a throttle valve capable of adjusting the flow rate at the outlet or the inlet of the exhaust fan 21 to adjust the throttle opening degree, or by increasing or decreasing the driving speed of the exhaust fan 21. When adjusting the exhaust air flow rate by increasing or decreasing the driving rotation speed of the exhaust fan 21, the rotation speed of the exhaust fan 21 is reduced to a certain value at a time ta before the driving of the motor 43 is started, and the agitating claw shaft is rotated. Time Tb after driving of No. 19 stopped
The deceleration rotation is continued until after elapse of, and the rotation speed of the exhaust fan 21 is increased to a constant value after the end of the deceleration rotation.
The time t at which the rotation of the motor 43 is started when the increased rotation is started.
The control is continued so that this operation is repeated until a.

That is, the heater 65 and the thermal catalyst 67, which constitute the deodorizing device 62, and the exhaust fan 77 for sending exhaust gas as exhaust air are driven for a certain period of time immediately before the stirring claw shaft 19 is rotated. It is done. The time ta and the time Tb are set according to the internal temperature detected by the temperature sensor 82 in the fermenter 1 and the total elapsed days (total input amount) of the automatic operation of the fermentation decomposition process, or arbitrarily. Configurable.

When the garbage and auxiliary materials are put into the fermenter 1 and the starter switch 81 is turned on to start the operation of the garbage processing machine 9, the fermenter 1
By adjusting the temperature of the inside and the amount of air and water by the drive control of the exhaust fan 21, the garbage in the fermenter 1 is maintained in an environment suitable for fermentation and decomposition, and the drive control of the motor 43 causes the agitating claw shaft 19 to reverse. By driving intermittently in the direction, the added garbage can be sequentially decomposed to promote composting.

Since immediately before the stirring nail shaft 19 is driven and the contents are agitated, the decomposition is promoted and odor is generated most. Therefore, as described above, the exhaust fan 21 is driven slowly. To reduce the air volume and send the air through the exhaust duct 22 into the deodorizing introduction pipe 64,
Is kept closed, and the exhaust gas is sent to the deodorizing device 62 via the connection pipe 64a. At the same time, in the deodorizing device 62, the heater 65 has already been heated to reach a temperature sufficient for decomposition, and the blown exhaust gas is heated, the odor is adsorbed and decomposed by the thermal catalyst 67, and the exhaust gas from which the odor is removed is removed. The wind is blown into the exhaust pipe 76. In addition, since the air volume is low while the air is sent to the deodorizing device 62, the exhaust gas can be sufficiently heated even if the heat capacity of the heater 65 is reduced.
Electrical burden can be reduced. Further, since the amount of air blow is small, the amount of dust passing through the filter 60 is small, and the heat catalyst 67 formed in the honeycomb shape is not clogged.

The exhaust air blown into the exhaust tube 76 is heated hot air. The air is blown against the side surface of the exhaust tube 76 to diffuse the flow, and at the same time, the air is blown by the exhaust fan 77. It is mixed with the outside air, stirred and cooled rapidly,
The air is sent to the front of the exhaust pipe 76 as it is, and the air holes 63a
a ... exhausted to the outside. Therefore, the heat catalyst 6
Even if it is heated to deodorize in step 7, the air is exhausted after being reliably cooled in the short exhaust pipe 76 accommodated in the deodorizing case 63, so that the hot air is exhausted as it is and does not harm the external environment.

On the other hand, while the driving of the stirring claw shaft 19 is stopped, the amount of fermentation decomposition is small and the generation of odor is small, and the rotation speed of the exhaust fan 21 is increased as described above. Sufficient oxygen can be supplied into the fermenter 1, the amount of exhaust air sucked by the exhaust fan 21 and sent to the exhaust duct 22 increases, and the amount of air in the deodorization introduction pipe 64 also increases. In this case, the switching lid 78 is rotated upward by the pressure of the exhaust air, the exhaust pipe 64b is opened, and the exhaust air flows into the space on the right side of the deodorizing case 63, and the right air hole 63a on the front surface of the deodorizing case 63. 63a ... exhausted to the outside as it is. While the stirring is stopped, the concentration of the exhaust gas in the fermenter 1 is low and the dust is small. Even if this air is sucked, the exhaust gas in the exhaust air is small. The external environment is not compromised.

During the exhaust with the exhaust pipe 64b opened, the exhaust air hardly flows into the deodorizing device 62 side, and the dust does not flow into the deodorizing device 62, and the thermal catalyst 67 is clogged. Without causing the thermal catalyst 67
Maintenance can be reduced. Further, during this time, no voltage is applied to the heater 65 or the like, the power consumption is reduced, and the running cost of the operation of the garbage disposal 9 can be reduced.

Further, even if the exhaust gas does not flow toward the deodorizing device 62 due to clogging of the thermal catalyst 67, the switching lid 78 is rotated upward and comes out of the exhaust pipe 64b. Therefore, there is no problem that the air is not supplied.

[0036]

The present invention is configured as described above.
The following effects are obtained. That is, as described in claim 1, in a garbage processing machine that sucks and exhausts exhaust gas from a fermenter that performs fermentation decomposition treatment of garbage using an exhaust unit,
An inlet pipe is provided between the fermenter and the deodorizer to guide the exhaust gas to the deodorizer, and the inlet pipe is provided with an openable and closable exhaust port so that the exhaust can be exhausted directly to the outside from the exhaust port. If it is occurring, close the outlet, deodorize with a deodorizer and exhaust to the outside.If air is sucked into the fermentation tank and exhaust gas is not sucked much, open the outlet and operate the deodorizer. By directly exhausting the gas without passing through, it is possible to reduce the burden on the deodorizing device, especially the maintenance burden due to clogging of dust and the like.

Further, as described in claim 2, an openable and closable lid is disposed above the exhaust port, and the lid is opened according to the amount of exhaust air. When the amount of exhaust gas is small, the outlet can be automatically opened and exhausted by the pressure of the air flow, and the opening and closing of the outlet is simple and simple. There is no need to do so, and handling is simplified.

According to a third aspect of the present invention, the amount of air exhausted by the exhaust means can be increased or decreased in accordance with the intermittent drive of the stirring claw shaft, so that the amount of exhaust air is reduced when stirring is performed and the amount of exhaust air is increased when stirring is stopped. Therefore, even when the lid is automatically opened with the air volume, the exhaust gas volume is reduced during agitation when the exhaust gas concentration is high so that the lid is not opened and the lid is not opened. Can be exhausted. On the other hand, when the agitation with less exhaust gas in the fermenter is stopped, the exhaust air volume sucked from the fermenter is increased, the lid is opened with the wind pressure, and the air is exhausted directly to the outside, so that it can be directly exhausted to the outside. Can also reduce odor leakage.

According to a fourth aspect of the present invention, there is provided a garbage disposal machine which sucks exhaust gas from a fermenter for fermenting and decomposing garbage through an exhaust means, sends it to a deodorizer having a thermal catalyst, and exhausts it. , Connect the exhaust stack to the outlet of the deodorizer,
Since the outside air introduction means is connected to the exhaust pipe, even if the exhaust air is heated and deodorized and exhausted to remove the odor with the thermal catalyst, it is forcibly mixed with the outside air at the outlet of the deodorizing device and rapidly cooled and exhausted. It can be deodorized and the hot air is not exhausted, keeping the external environment in good condition.

Further, the exhaust pipe communicates with the outlet of the deodorizing device at right angles to the outlet of the deodorizer, and the outside air introduction means is connected to one end of the exhaust pipe, so that the hot air hits the side of the exhaust pipe and diffuses. Then, by blowing the air to the outside air, the exhaust air mixed and heated efficiently can be rapidly cooled and exhausted as it is. Further, since the deodorized hot air does not directly hit the outside air introducing means, the durability of the outside air introducing means can be improved.

According to a sixth aspect of the present invention, a fermenter for fermenting and decomposing garbage is accommodated in a casing, and the casing is placed on a deodorizing case so that both communicate with each other. Divided into two spaces, one space is used as an exhaust path that directly guides exhaust gas to the outside, and the other space is equipped with a deodorizing device as an exhaust path that leads to the outside after deodorization, and both exhaust paths can be switched through a valve via a valve Therefore, it is possible to configure a functional deodorizing unit that reduces the burden on a deodorizing device that can be directly evacuated or deodorized and evacuated or switched according to the content ratio of the exhaust gas outside the casing containing the fermenter. . Then, this functional deodorizing unit, which is configured separately from the garbage disposal machine, can be mounted on demand, and the mounting configuration is to place the garbage disposal machine on the deodorizing case, and to the side. There is no need to provide extra space.
