Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small garbage treating machine for composting household garbage produced by using aerobic bacteria and the like, and more particularly to a rotary drum type garbage treating machine.

[0002]

2. Description of the Related Art Conventionally, as this type of rotary drum type garbage processing machine, there is a garbage processing machine disclosed in Japanese Patent Application Laid-Open No. 2-56290 and Japanese Patent Application No. 4-61910 filed by the present applicant. .

As shown in FIG. 4, the garbage processing machine disclosed in Japanese Patent Application No. 4-61910 has a fixed support shaft 31 fixed laterally on a leg 30, and a periphery of the fixed support shaft 31. The rotary drum type processing container 21 is rotated by manual operation of the rotary handle 20, the lid 22 is opened by removing the closing lid hook 24 on the top side of the rotary drum type processing container 21, and the bottom part of the rotary drum type processing container 21. Vent pipe 2 penetrated to the side
9, a pair of cross-shaped stirring blades 32 mounted and fixed to the fixed support shaft 31, a heater mounting bracket 33 mounted on the lower end of the stirring blade 32, and a pair of brackets 33.
The reinforcing bar 36 is provided between the reinforcing bar 36 and the electric heater 40 fixed along the reinforcing bar 36, and the cord 41 of the electric heater 40 has a wiring hole 35 formed in the fixed support shaft 31. It is pulled out to the outside through a hollow portion in the fixed support shaft 31.

After the lid 22 is opened in the processing container 21 and the garbage is put therein, the lid 22 is closed and the rotary handle 20 is rotated to rotate the processing container 21, whereby the introduced garbage is already discharged. Mix with composted garbage and aerobic bacteria (composting medium). The composting process of raw garbage is performed by such an operation. However, when the outside air temperature becomes low in winter or the like, the electric heater 40 is turned on to heat the inside of the processing container 40, so that the aerobic bacteria are aerated. It can activate compost and promote composting even in cold weather.

[0005]

However, the above-mentioned rotary drum type garbage treatment machine has the following problems.

That is, since the heating by the electric heater 40 is for optimizing the environmental temperature of aerobic bacteria (medium for composting), the electric heater 40 is at a position (from the fixed support shaft 31) enough to be buried in the medium for composting. Is also in a low position). However, since heat conduction is the mainstream for heating the composting medium by the electric heater 40, if the volume of the composting medium increases under cold conditions, the heat capacity also increases, making uniform heating as a whole difficult. Only the portion near the electric heater 40 has an abnormally high temperature, and the distant portion remains at a low temperature. Uniform heating can be achieved by increasing the number of the electric heaters 40 and arranging them in a dispersed manner, but the volume of the electric heaters, mounting brackets, etc. becomes large, so the composting processing volume (processing capacity) decreases. Becomes

In view of the above problems, an object of the present invention is to provide a rotary drum type garbage treatment machine capable of uniformly heating the composting medium by heating the atmosphere of the composting medium with warm air. To do.

[0008]

In order to solve the above-mentioned problems, the present invention is characterized by heating with warm air and automatic stirring. That is, the present invention is directed to a fixed support shaft laterally fixed to a leg, a rotary drum type processing container that rotates at a low speed around the fixed support shaft by driving rotation of an electric motor, and a blower with a blower temperature controller. And an air supply pipe for discharging air into the rotary drum type processing container through a hollow portion on one end side of the fixed supporting shaft, and air in the rotary drum type processing container to the other end of the fixed supporting shaft. And an exhaust pipe for discharging to the outside of the rotary drum type processing container through the hollow portion on the side. In such a configuration, it is desirable that the discharge port of the air supply pipe is located at a lower position than the fixed support shaft and the intake port of the exhaust pipe is located at a higher position than the fixed support shaft. Further, it is preferable that the discharge port of the air supply pipe and the intake port of the exhaust pipe are located in a void region in the rotary drum type processing container, avoiding a passage region of the composting medium accompanying agitation. Further, it is desirable that the exhaust port of the exhaust pipe is opened substantially downward.

It is desirable to provide strainers at the discharge port of the air supply pipe and the intake port of the exhaust pipe.

[0010]

As described above, in the garbage disposal of the present invention, the rotating drum type processing container is slowly rotated at a low speed by the electric motor. Therefore, when the garbage is put in, the user rotates the rotary drum automatically without manually rotating it, so that the mixing of the composting medium and the garbage and the aeration continue to proceed to improve the composting efficiency. Can be planned. Since air is blown into the rotary drum that constantly rotates at a low speed through the air supply pipe, it is not necessary to provide a ventilation hole in the rotary drum.

Since the rotary drum has no ventilation hole, the rotary drum can be downsized and the garbage processing capacity can be increased, and the garbage can be prevented from falling from the ventilation hole. When the outside air temperature is relatively low or the amount of garbage is large, the temperature inside the rotating drum can be raised by raising the air temperature, and the temperature of the composting medium can be optimized even in cold regions. . It is possible to heat the composting medium together with an electric heater, but since warming by warm air is due to contact between the warm air and the agitated composting medium, aerobic bacteria can be contacted like a heater. Since the atmosphere is appropriately heated without directly heating it, uniform heating can be achieved as a whole. Further, since the air supply pipe and the exhaust pipe are arranged through the hollow portion (hole) of the fixed support shaft, the internal volume of the processing container is not excessively occupied by the pipe, and the high processing efficiency is maintained regardless of the high processing efficiency. It is possible to realize a garbage processing machine with a large processing volume.

By the way, depending on the temperature setting of the warm air, 50
Although hot air exceeding ° C can be blown into the processing container, even if the composting medium is exposed to relatively hot air (hot air), the aerobic bacteria will suddenly die or decrease. However, maggots, flies, etc. that have swept inside the processing container die when exposed to such hot air. Therefore, it is possible to exterminate maggots and flies by periodically blowing hot air in addition to blowing warm air to heat the composting medium at an appropriate temperature. In the past, the control of maggots and flies was carried out by spraying insecticides. According to this, the compost becomes contaminated with insecticides, but by appropriately blowing hot air, it is possible to physically exterminate maggots and flies without killing aerobic bacteria.

When the discharge port of the air supply pipe is set lower than the fixed support shaft and the intake port of the exhaust pipe is set higher than the fixed support shaft, the discharged blast (warm air) rises. At the same time, it makes good contact with the composting medium and is exhausted from the intake port to the outside, resulting in good heat exchange efficiency. If the discharge port of the air supply pipe and the intake port of the exhaust pipe are located in the void area of the rotating drum type processing container that avoids the passage area of the composting medium associated with agitation, the discharge port of the air supply pipe and the exhaust gas Since the intake port of the tube is not closed by the composting medium, the fluid resistance is small, and the warm air blower can be downsized and the exhaust efficiency can be improved. Further, if the exhaust port of the exhaust pipe is set to open substantially downward,
It is possible to prevent rainwater and the like from entering the container through the exhaust port. Furthermore, when strainers are installed at the discharge port of the air supply pipe and the intake port of the exhaust pipe, there is no concern that the composting medium will enter the air supply pipe or the exhaust pipe, and insects such as flies will go in and out of the container. Nor.

Embodiments of the present invention will now be described with reference to the accompanying drawings.

FIG. 1 is a partially cutaway front view showing a drum rotary type garbage disposal according to an embodiment of the present invention, and FIG. 2 is a vertical sectional side view of the same.

The rotary drum type garbage processing machine of this embodiment has a fixed support shaft 31 fixed laterally on the leg portion 30, a motor stand 41 fixed in the middle of the leg portion 30, and a motor support base 41 fixed thereon. A fixed electric motor 42, a rotating drum-shaped processing container 51 having a regular octagonal columnar section, which rotates slowly around the fixed support shaft 31 by a driving rotational force of the electric motor 42 via a chain belt 43, and a regular octagonal columnar side surface. Out of the above, the garbage input port 52 formed on the upper inclined surface 51a, the lid (not shown) that opens and closes the input port 52, and the heater mounting bracket fixed to the rotary support shaft 31 at a distance from each other. 61 and a downward facing rectangular frame-shaped electric heater 60 fixed to each heater mounting bracket 61.
The code 0 (not shown) is pulled out to the outside through a wiring hole (not shown) formed in the fixed support shaft 31 and a hollow portion in the fixed support shaft 31. In this example, the blower stand 44 fixed to the upper end side of the leg portion 30, the blower with the blower temperature controller (warmer) 45 fixed thereon, the rotation speed of the electric motor 42, and the warm blower are also provided. It has a control panel 46 which can be operated to control the wind speed, warm air temperature, etc. Here, the air supply pipe 70 of the air blown out from the air blower 45 is passed through the hollow portion 31a on one end side of the fixed support shaft 31,
It is bent downward in the fixed support shaft 31 in the drum type processing container 51 and extends downward from the hole of the fixed support shaft 31. The end of the downward extension 71 is the discharge port 72, and the strainer 7
3 is provided. On the other hand, the exhaust pipe 80 is passed through the hollow portion 31b on the other end side of the fixed support shaft 31.
The exhaust pipe 80 projecting outward from No. 1 is bent downward, and its end portion forms an exhaust port 81 that opens downward. The exhaust pipe 80 is bent upward in the fixed support shaft 31 in the drum type processing container 51, and extends upward from the hole of the fixed support shaft 31. The terminal end side of the downward extension portion 82 is bent so as to be parallel to the fixed support shaft 31, the end thereof is an intake port 83, and a strainer 84 is provided.

After the garbage is put into the processing container 51, the lid is closed, and the control board 46 is operated to operate the processing container 51 by the low-speed automatic rotation by the electric motor 42. With such automatic rotation, raw garbage and aerobic bacteria (composting medium) are mixed well with new raw garbage, and oxygen is constantly supplied to the aerobic bacteria. The composting efficiency is significantly improved compared to the form garbage processor. Further, when the outside air temperature becomes low in winter, etc., the electric heater 60 is turned on to heat the inside of the processing container 51 to activate aerobic bacteria and promote composting even in cold weather. Has become. In addition, the power cord (not shown) of the electric heater 60 of this example is a rotary support shaft 31.
And is extended toward the control panel 46 side through a gap between the air supply pipe 70 and the air supply pipe 70 inserted therein.

Since air can be blown into the rotary drum type processing container 51 which constantly rotates at low speed by the blower 45 through the air supply pipe 70, the processing container 51 is not provided with a vent hole. The fact that the rotating drum has no vents means
It is possible to reduce the size of the rotary drum and increase the capacity for processing garbage, and to prevent the garbage from falling through the ventilation hole.

When the blowing temperature is increased, not only the electric heater 60 heats the temperature, but also the temperature in the rotary drum can be raised by the warm air, and the temperature of the composting medium can be optimized even in the cold district. Since the heating by the electric heater 60 directly heats aerobic bacteria by contact, it is impossible to perform high temperature heating, and it is necessary to disperse the electric heater 60 in a distributed manner. Will also grow.
However, as in this example, warm air is blown by the blower 45 into the container 5
If it is blown into 1, it is possible to uniformly heat the sedimentation medium. In particular, in this example, the air supply pipe 70 and the exhaust pipe 80 are hollow portions (holes) of the fixed support shaft 31.
Since the internal volume of the processing container 51 is not excessively occupied by the pipes, it is possible to realize a garbage processing machine having a large processing volume regardless of high processing efficiency.

By operating the control panel 46, it is possible to set the temperature of warm air to 50 ° C. or higher. Here, even if the composting medium is exposed to a relatively high-temperature hot air (hot air), the aerobic bacteria are not rapidly killed or reduced, but the maggots, flies, etc. that have swept inside the processing container 51 Will die when exposed to such hot air. Therefore, it is possible to exterminate maggots and flies by periodically blowing hot air in addition to blowing warm air to heat the composting medium at an appropriate temperature. Conventionally, extermination of maggots and flies has been carried out by spraying insecticides, but according to this, compost is contaminated with insecticides. However, in this example, by appropriately blowing hot air, it is possible to physically exterminate maggots and flies without killing aerobic bacteria.

Further, in this embodiment, the discharge port 72 of the air supply pipe 70 is set at a position lower than the fixed support shaft 31, and the exhaust pipe 8
The intake port 83 of 0 is set at a position higher than the fixed support shaft 31. Therefore, the discharged warm air is in good contact with the composting medium while rising, and is exhausted to the outside from the intake port 83.
Good heat exchange efficiency.

FIG. 3 is a vertical cross-sectional side view of the food waste disposer showing another manner of mounting the air supply pipe and the exhaust pipe. In FIG. 3, the discharge port 72 of the air supply pipe 70 and the intake port 8 of the exhaust pipe 80 are shown.
3 is located in the void region 92 of the rotary drum type processing container 51, avoiding the passage region (retention region) 91 of the composting medium 90 accompanying the stirring. Since the discharge port 72 of the air supply pipe 70 and the intake port 83 of the exhaust pipe 80 are not blocked by the composting medium 90, the fluid resistance is small, and the warm air blower can be downsized and the exhaust efficiency can be improved.

Further, as shown in FIG. 1, when the exhaust port 81 of the exhaust pipe 80 is set to open substantially downward, rainwater and the like can be prevented from entering the container through the exhaust port. Since strainers 73 and 84 are provided at the discharge port 72 of the air supply pipe and the intake port 83 of the exhaust pipe,
There is no concern that the composting medium will enter the air supply pipe or exhaust pipe, and insects such as flies will not enter or leave the container.

As described above, in the rotary drum type garbage disposal of the present invention, the rotary drum type processing container is automatically rotated at a low speed by the electric motor, and the blower temperature controller. It is characterized in that the attached blower blows the blown air into the container through the rotary support shaft. Therefore, the following effects are obtained.

The user does not have to manually rotate the rotary drum when throwing in the garbage, and since it continues to rotate at a low speed all the time, the mixing of the composting medium and the garbage and the aeration continue to proceed, and The efficiency of conversion can be improved.

Since air is blown into the rotary drum which constantly rotates at a low speed through the air supply pipe by the blower, it is not necessary to provide a ventilation hole in the rotary drum. Since it is not necessary to provide a ventilation hole in the rotary drum, it is possible to reduce the size of the rotary drum and increase the amount of garbage processing,
Further, it is possible to prevent raw garbage from falling from the ventilation hole.

Further, since hot air can be blown in, the temperature in the rotary drum can be raised, and the temperature of the composting medium can be optimized even in cold regions. It is possible to heat the composting medium together with an electric heater, but since warming by warm air is due to contact between the warm air and the agitated composting medium, aerobic bacteria can be contacted like a heater. Since the atmosphere is appropriately heated without directly heating it, uniform heating can be achieved as a whole. In particular, in the present invention, since the air supply pipe and the exhaust pipe are arranged through the hollow portion (hole) of the fixed support shaft, the internal volume of the processing container is not excessively occupied by the pipe, and high processing efficiency is achieved. Regardless of this, it is possible to realize a garbage processing machine with a large processing volume. In addition to hot air blowing for the appropriate temperature of the composting medium as described above, by periodically blowing hot air, it is possible to physically exterminate maggots and flies and are not contaminated with insecticides. You can get compost.

When the discharge port of the air supply pipe is set at a position lower than the fixed support shaft and the intake port of the exhaust pipe is set at a position higher than the fixed support shaft, the discharged warm air rises and composts. Since it is in good contact with the medium and is exhausted from the intake port to the outside, the heat exchange efficiency is good.

When the discharge port of the air supply pipe and the intake port of the exhaust pipe are located in the void area in the rotary drum type processing container, avoiding the passage area of the composting medium accompanying agitation, the discharge of the air supply tube Since the outlet and the inlet of the exhaust pipe are not blocked by the composting medium, the fluid resistance is small, and the warm air blower can be downsized and the exhaust efficiency can be improved.

Furthermore, when the exhaust port of the exhaust pipe is set to open substantially downward, rainwater and the like can be prevented from entering the inside of the container through the exhaust port.

Furthermore, when a strainer is provided at the discharge port of the air supply pipe and the intake port of the exhaust pipe, there is no concern that the composting medium will enter the air supply pipe or the exhaust pipe, and insects such as flies will move inside and outside the container. There is no going in or out.
