Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a kitchen waste processing machine for drying kitchen waste.

[Prior art]

In Europe and the United States, disposers are often used as household kitchen waste disposal machines, but Western-style disposers cannot be used in Japan because sewage channels and sewage treatment facilities are not in place. Furthermore, various types of kitchen waste processing machines for domestic use have been proposed.

A typical example of this is the deposer system, which is equipped with a solid content recovery device, but this system eliminates the problem of dirty drainage, which makes it difficult to comply with the drainage standards of the Sewerage Act, and instead of blocking the drainage pipes. Therefore, it is necessary to clean the filter frequently. In addition, since the collected kitchen waste contains a large amount of water, it rots quickly and generates a bad odor, making it difficult to put it into practical use. A vacuum drying method has also been proposed in which drying is performed under reduced pressure, but this method requires a reduced pressure device and a structure that can withstand atmospheric pressure while maintaining low pressure, resulting in an increase in product price.

[Summary of the invention].

This invention was made to solve the above-mentioned conventional problems. Kitchen waste is heated with hot air in a sealed drying chamber, and the generated water vapor is guided outside the drying chamber to be cooled and collected as water.
This drying method allows kitchen waste to be dried uniformly, reduces weight and volume, prevents the generation of odors after processing, and allows the processed kitchen waste to be automatically discharged without dirtying hands. We provide a kitchen waste disposal machine.

A partition plate 4 is attached, and this partition plate 4 is inscribed in the inner end surface and inner peripheral surface of the drying chamber 2, and a large number of small holes 4a are provided projecting over the entire area of the partition plate 4.

Further, at the bottom of the drying chamber 2, there is a discharge port 2& for discharging processed kitchen waste, at the bottom 9 on the side there is a hot air outlet 2b consisting of a large number of small holes, and at the top, the upper surface of the case 1 Each of the input ports 6 for inputting processing kitchen waste is provided with an opening 9, and each of the input ports 6 is closed by a lid 7 having a gasket 7a attached to the outer periphery. Reference numeral 8 denotes a filter that is integrally attached to the lid 7 so as to be located in the input port 6, and 9 is a bypass passage that forms a hot air circulation circuit for drying kitchen waste with respect to the drying chamber 2. Reference numeral 9 includes a casing 10 whose one end is connected to the air outlet 2b of the drying chamber 2, a suction port 10a provided at the other end of the casing 10, and an introduction hole 6' provided at the input port 6.
The casing 10 includes an inlet pipe 11 that communicates with the inlet 1, and a circulation fan 12 inside the casing 10.
The casing 10 is located at the position 0a, and the casing 10
A heater 13 is disposed on the side corresponding to the air outlet 2b. 14 has one end connected to the water vapor discharge hole 1 of the introduction pipe 11.
1&, and the other end protrudes into the case 1.This drain pipe 14 cools and liquefies the water vapor generated by hot air heating of kitchen waste in the drying room 2. The liquid flowing out from the outer protruding end of the case 1 is discharged to a sewer pipe or the like. Also, 1
Reference numeral 5 denotes an opening/closing lid for opening/closing the discharge port 2a of the drying chamber 2, and a gasket 16 for sealing the discharge port 2a is attached to the outer periphery of the lid.
The control lever 18 is supported by one end of an operating lever 18 which is rotatably mounted on the outer wall of the case 2 by a pin 17, and the other end thereof projects outside the case 2. Reference numeral 19 denotes a guide tube attached to the lower surface of the drying chamber 2 so as to surround the discharge port 2a and its opening/closing i15. Below the guide tube 19, a storage box 20 for storing all the processed kitchen waste can be taken in and out. It is located.

Next, the operation of this embodiment configured as described above will also be explained.

When processing kitchen waste, first remove the lid 7 and filter 8 9, and feed the unprocessed kitchen waste 21 into the drying chamber 2 through the input port 6.
Put it inside. At this time, since the partition plate 4 is arranged to partition the inside of the drying chamber 2 into upper and lower sections as shown in FIG. 2, the input kitchen waste 21 is placed on the partition plate 4.

After putting in a predetermined amount of unprocessed kitchen waste 21, the lid 7 and filter 8 are attached to the inlet 6, and then the blower fan 12 and heater 13 are energized to start them. Blow fan 12
When the is driven, the air in the drying chamber 2 is sucked through the filter 8, the intake port 6& of the inlet 6, and the introduction pipe 11 as shown by the arrow, and is further forced into the casing 10 toward the outlet 2b. It is heated by the heater 13 and discharged from the air outlet 2b into the space A of the drying chamber 2 divided by the partition plate 4. The heated air discharged into the space A is blown into the piled kitchen waste 21 through the small holes 4a of the partition plate 4, and by heating this kitchen waste 21, the moisture contained therein is evaporated. As a result, the pressure inside the drying chamber 2 increases
The temperature rises due to the temperature expansion of the water vapor and air evaporated from the drain pipe 14, and the water vapor and air corresponding to this pressure increase flow into the drain pipe 14 due to the pressure difference with the open end of the drain pipe 14 which is open to the atmosphere. The water vapor flowing in the drain pipe 14 toward the open end is liquefied by natural cooling, and the liquefied water is discharged from the open end to a sewer pipe or the like.

When the temperature inside the drying chamber 2 reaches a predetermined temperature as waterfall drying progresses due to continuous circulating heating of warm air, the expansion of the air almost stops, and therefore only liquefied moisture flows out from the drain pipe 14. will be discharged.

Further, during the drying operation, the blower fan 12 and heater 13 are stopped, and the motor 5 is driven to rotate the partition plate 4 in the direction of the arrow in FIG. 3 to stir the kitchen waste 21. After this stirring is completed, the partition plate 4 is placed in the state shown in FIG. 2 again, the blower fan 12 and the heater 13 are started, and hot air drying is performed again.

Thereafter, by repeating the warm air drying operation and the kitchen waste stirring operation in the same manner, the kitchen waste 21 is dried to a uniform state with a low moisture content.

When the drying process for kitchen waste is completed by the above operation, the operation lever 18 is rotated in the direction of the arrow in FIG. 4 to open the opening/closing lid 15 and open the discharge port 2a. By setting and driving the motor 5 to rotate the partition plate 4 in the direction of the arrow, the dried kitchen waste 21A is pushed out by the partition plate 4 from the discharge port 2a to the guide pipe 19 and discharged into the storage box 20.

〔Effect of the invention〕

As explained above, according to the present invention, kitchen waste is dried by hot air circulating heating, and the water vapor generated from the kitchen waste is cooled and liquefied at this time, so that there is very little contamination of drainage water due to kitchen waste, and the kitchen waste is easily dried. In addition to its excellent thermal efficiency, treated kitchen waste can be handled in the same way as regular dust. In addition, we have adopted a method in which the kitchen waste is stirred by rotating the partition plate during the drying of the kitchen waste, so that the kitchen waste can be dried uniformly to a state with a low moisture content, and as a result, the volume and weight of the kitchen waste can be reduced by several minutes. 1 (''/4) or less, and there is no odor after treatment.Furthermore, the lid installed at the bottom of the drying chamber can be opened using an external operating lever, and the lid installed at the bottom of the drying chamber can be opened using an external operating lever. By rotating the plate, it is automatically discharged outside the drying room, which saves the user the trouble of taking out kitchen waste, and also has a simple structure that reduces costs.
