Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposal apparatus for incinerating kitchen garbage (garbage) generated in a kitchen.

2. Description of the Related Art Disposal of garbage that occurs in homes and commercial kitchens is performed by allowing natural dehydration to take place for a while because the garbage is poured into a mesh-shaped garbage storage basket that is installed at the outlet of the tank in the kitchen sink. After that, they are generally put in a plastic bag or the like and stored in a kitchen garbage storage cabinet, and then, on a predetermined garbage collection day, are transported together with the bags to a common collection point for collection and disposal.

However, in such a method, the garbage is spoiled by the date of garbage collection, so that not only a bad smell is generated but also unsanitary.

As a device that can solve this problem, the applicant has developed a kitchen garbage disposal device that irradiates microwaves with kitchen waste, such as garbage, vegetables and fruits, to dry and incinerate it (eg, Japanese Patent Application No. 61-130786, Japanese Patent Application No. No. 61-147356).

However, these devices do not accept, dry, incinerate,
Since the series of ash treatment processes is performed in a single room, there is a limit to the amount of garbage that can be incinerated at one time. That is, drying, incineration, and ash cooling of the garbage each require several tens of minutes, so that the time required for incinerating the garbage and storing the ash in the container is about an hour or more. Therefore, in places where kitchen garbage is generated one after another, such as in restaurants, there is an inconvenience that when kitchen garbage exceeding the processing capacity is generated, the excess kitchen garbage must be separately stored.

An object of the present invention is to solve such a problem, and an object of the present invention is to provide a garbage disposal apparatus that can efficiently incinerate a large amount of garbage even in a restaurant or the like where the garbage is likely to be generated each time it occurs. .

Means for Solving the Problems In order to achieve this object, the kitchen waste treatment apparatus of the present invention is provided with a kitchen waste receiving area, microwaves irradiating microwaves to the kitchen waste, which are sequentially arranged in a loop in a housing. An incineration area having a generator and an ash disposal area for the garbage are provided, and further, garbage transport means for transporting a container for accommodating the garbage in the order of the receiving area, the incineration area, and the ash disposal area are provided. Is what it is.

Action With this configuration, automation is possible with a small configuration, and a large amount of kitchen waste can be efficiently incinerated and treated as harmless dust.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a cross-sectional view of a kitchen waste treatment apparatus according to one embodiment of the present invention, FIG. 2 is a side view thereof, and FIGS. 3 and 4 are perspective views of main parts thereof.

In FIGS. 1 and 2, reference numeral 1 denotes a housing, which is made of a heat-resistant material and whose inner surface is covered with a metal to take measures to prevent microwave leakage. Of course, this may be made of metal. Reference numeral 2 denotes a rotating shaft, which is rotatably supported at a substantially central portion of the housing 1 and is connected to a motor 3 disposed at a lower portion of the housing 1 by a belt 4. It is driven to rotate counterclockwise. Reference numeral 5 denotes a metal partition plate, four of which are attached in a cross shape to the rotating shaft 2, and in the state shown in FIG. This prevents microwave leakage from the room that is partitioned. At this time, in the inside of the housing 1, the place corresponding to the first quadrant is the garbage receiving position 6, the place corresponding to the second quadrant is the garbage drying position 7, the place corresponding to the third quadrant is the garbage incineration position 8, The place corresponding to the fourth quadrant is the ash processing position 9
It is divided into four such as. That is, in the housing 1, a kitchen receiving area, a kitchen drying area, a kitchen incineration area, and a kitchen ash processing area are sequentially arranged in a loop. Reference numeral 10 denotes an arm, which is formed in a cross shape, and is attached to both ends of the rotary shaft 2 so as to be located at an intermediate portion between the partition plates 5 adjacent to each other as shown in FIG. 11
Is a semi-cylindrical container for storing kitchen garbage, having a structure as shown in FIG. 4, and an arm positioned in the rotation axis direction.
Each is rotatably mounted between the tip portions of the ten members. Numeral 12 denotes a microwave absorbing and heating element, which is provided in a projecting manner at a central portion inside each of the containers 11. This is made of, for example, silicon carbide, and when irradiated with microwaves, absorbs the microwaves to reach a temperature of 700 to 900 ° C. and glows red. 13 and 14 are microwave generators, each of which has a housing 1

Open the open / close lid 17 and put the garbage (not shown) into it.
The lid 17 is closed to start the garbage disposal operation. Then
The motor 3 operates and the rotating shaft 2 rotates 1/4 turn, and the first container 11 at the garbage receiving position 6 moves to the garbage drying position 7,
The next second container 11 moves to the garbage receiving position 6. After this movement is completed, the microwave generator 13 is oscillated. The microwave is applied to the garbage in the first container 11 at the garbage drying position 7 through the waveguide 15. This irradiation evaporates water and dries the kitchen waste. The time required for drying the garbage depends on the amount of the garbage, but it is about several tens of minutes for a normal household discharge. The drying state is detected by a humidity sensor or the like, and the oscillation operation of the microwave generator 13 is stopped. At the end of drying, the second container 11 at the garbage receiving position 6 is in a standby state for receiving garbage, so that the opening / closing lid 17 is opened, garbage is put into it, and then closed. And, the motor 3 is
Is further rotated by 1/4, and the first container 11 is placed in the kitchen drying position 7.
From the garbage incineration position 8 and the second and third containers 11 are moved to the garbage drying position 7 and the garbage receiving position 6, respectively. When this movement is completed, the microwave generators 13 and 14 oscillate. Since the garbage in the first container 11 is sufficiently dried at the garbage drying position 7, the microwave energy is absorbed by the microwave absorbing heating element 12. As a result, the microwave absorbing and heating element 12 generates heat and glows red. The kitchen waste is further heated by the microwave absorbing heating element 12, ignites and burns. On the other hand, the garbage in the second container 11 at the garbage drying position 7 is dried by being irradiated with microwaves from the microwave generator 13. The completion of combustion of the garbage in the first container 11 is detected by a temperature sensor or the like, and the drying of the garbage in the second container 11 is detected by a humidity sensor or the like, and the microwave generator 13, After stopping the oscillation of 14 respectively, the open / close lid 17 is opened, and the garbage is put into the third container 11 at the garbage receiving position 6. Then, the rotating shaft 2 is further rotated by a quarter turn, and the first container 11 is moved to the ash processing position 5. Accordingly, the second, third, and fourth containers 11 move to the kitchen waste incineration position 8, kitchen waste drying position 7, and kitchen waste receiving position 6, respectively. When the dust in the first container 1 is cooled at the ash processing position 5 and then the container 11 is turned over, the dust in the container 11 is put into the ash tray 18.

In this way, a series of operations can be repeated, and all the steps of receiving, drying, burning, and ashes garbage can proceed simultaneously.

By setting the timing of the movement to each position in accordance with the step requiring the longest time among the steps, each step can be surely executed.

In the apparatus of the above embodiment, the number of steps for processing the garbage may be increased so that the garbage processing operation can be performed substantially continuously. Conveyors A and B may be provided as shown by broken lines so that kitchen waste can be continuously processed.

In the kitchen waste drying position and kitchen waste incineration position, odors and various harmful gases may be generated. If there is a possibility of this, harmful components are burned using a catalyst filter or the like, so that exhaust gas having substantially no toxicity can be obtained.

The opening / closing lid 62 is closed to start the garbage disposal operation. Then
The motor operates to rotate the rotary shaft 52 by 1/3 rotation. The first container 58 at the garbage receiving position 54 is thereby moved to the garbage drying and incineration position 55 in the housing 51, and the next second container 58 is moved to the garbage receiving position 54. After this move is complete,
The microwave generator 60 is oscillated. Microwave is a waveguide
The garbage in the first container 58 at the garbage drying and incineration position 55 is irradiated through 61. This irradiation evaporates water and dries the kitchen waste. After the evaporation of the water is completed, the microwave energy is intensively absorbed by the microwave absorbing heating element 59,
The microwave heating element 59 glows red. The dried kitchen waste is ignited by the microwave heating element 59 and burns. The end of incineration is detected by a temperature sensor or the like, and the oscillation operation of the microwave generator 60 is stopped. At the end of incineration, the second container 58 at the kitchen waste receiving position 54 is in a standby state for kitchen waste reception.
Open, put the garbage in it and close. Then, the motor further rotates the rotating shaft 52 by 1/3, moves the first container 58 from the refuse drying and incineration position 55 to the ash treatment device 8, and moves the second and third containers 58 to the garbage drying and incineration position 55, respectively. Is moved to the garbage receiving position 54. When this movement is completed, the microwave generator 60 oscillates again to dry and burn the garbage in the second container 58 at the garbage drying and incineration position 55. After the dust in the first container 58 is cooled at the ash processing position 56, the container 58 is inverted and the dust in the container 58 is put into the ash tray 63.

In this way, a series of operations can be repeated, and all the steps of receiving, drying, burning, and ashes garbage can proceed simultaneously.
