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 America, 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 a disposer system equipped with a solid content recovery device;
Dirty drainage not only makes it difficult to comply with the drainage standards of the Sewerage Law, but also clogs the drain pipes.
It is necessary to clean the filter frequently. Also,
The collected kitchen waste contains a large amount of water, which causes problems such as rapid decomposition and the generation of bad odors, and has also been difficult to put into practical use. A vacuum drying method has also been proposed in which the product is dried under reduced pressure, but this has the problem of increasing the product price because it requires a pressure reducing device and a structure that can withstand atmospheric pressure while maintaining low pressure.

[Summary of the invention]

This invention was made to solve the above-mentioned conventional problems, and is a drying method in which kitchen waste is heated with hot air in a closed drying chamber, and the steam generated by this is guided outside the drying chamber, cooled, and extracted as water. By doing so, we provide a kitchen waste disposal machine that can uniformly dry kitchen waste, reduce its weight and volume, prevent the generation of odors after processing, and automatically discharge processed kitchen waste without getting your hands dirty. There is something to do.

In addition, there is a discharge port 2a at the bottom of the drying chamber 2 for discharging processed kitchen waste, a warm air outlet 2b consisting of a large number of small holes near the bottom of the side, and a hot air outlet 2b on the top surface of the case 1 at the top. Each of the input ports 6 is provided with an open input port 6 for inputting processing kitchen waste, and each input port 6 is closed by a lid 7 having a gasket 7a attached to the outer periphery thereof. 8 is a filter integrally attached to the lid 7 so as to be located in the inlet 6; 9 is a bypass passage forming a hot air circulation circuit for drying kitchen waste with respect to the drying chamber 2; The passage 9 includes a casing 10 whose one end is connected to the air outlet 2b of the drying chamber 2, and an inlet 10a provided at the other end of the casing 10.
and an inlet pipe 11 that communicates between the inlet 6a provided in the inlet 6, and a circulation fan 12 is installed in the casing 10 between the inlet 1 and the inlet 6a.
Furthermore, a heater 1 is disposed at the side corresponding to the air outlet 2b in the casing 10.
3 are arranged. 14 connects one end to the introduction pipe 1
This drain pipe 14 is a spiral water vapor cooling drain pipe connected to the water vapor exhaust hole 11a of the drying chamber 2, and has the other end protruding into the case 1. Water vapor is cooled and liquefied, and the liquid flowing out from the outer protruding end of the case 1 is discharged to a sewer pipe or the like. Further, reference numeral 15 denotes an opening/closing lid for opening and 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 operating lever 18 is rotatably mounted on the outer wall of the case 2 by a pin 17, and the other end thereof is supported by one end of the operating lever 18. 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 lid 15. Below the guide tube 19, a storage box 20 for storing processed kitchen waste is placed so that it can be taken in and out. It's been done. Next, the operation of this embodiment configured as described above will also be explained.

When processing kitchen waste, first, the lid 7 and filter 8 are removed, and unprocessed kitchen waste 21 is introduced into the drying chamber 2 through the input port 6. At this time, since the partition plate 4 is arranged to divide the interior of the drying chamber 2 into upper and lower sections as shown in FIG.
1 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. When the blower fan 12 is driven, the drying chamber 2
The air inside is sucked through the filter 8, the inlet 6a of the inlet 6, and the inlet pipe 11 as shown by the arrow, and is further forced into the casing 10 toward the outlet 2b, heated by the heater 13, and then From there, it is discharged 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 estimated kitchen waste 21 through the small holes 4a of the partition plate 4, and by heating the kitchen waste 21, the moisture contained therein is evaporated. Along with this, the pressure inside the drying chamber 2 rises due to the temperature expansion of the water vapor and air evaporated from the kitchen waste 21, and the water vapor and air corresponding to this pressure rise reach the open end of the drain pipe 14 that is open to the atmosphere. It flows into the drain pipe 14 with a pressure difference of . The water vapor flowing inside the drain pipe 14 toward the open end is liquefied by natural cooling,
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 the hot air drying progresses due to continuous hot air circulation heating, the expansion of the air almost stops, and liquefied moisture flows out from the drain pipe 14. only will be discharged.

Further, during the drying operation described above, 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 hot air drying operation and the stirring operation of the kitchen waste in the same manner, the kitchen waste 21 is made uniform and has 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. Then, by driving the motor 5 and rotating the partition plate 4 in the direction of the arrow, the dried kitchen waste 21A is pushed out from the discharge port 2a into the guide pipe 19 by the partition plate 4 and discharged into the storage box 20.

[Effects of the Invention] As explained above, according to the present invention, the 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 extremely little contamination of the waste water by the kitchen waste. In addition to the excellent thermal efficiency of drying kitchen waste, the processed kitchen waste can be handled in the same way as normal 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. In addition to being able to reduce the amount of water to less than 1 (1/4), there is no odor generated after the treatment. Furthermore, processed kitchen waste is automatically discharged outside the drying room by opening the lid installed at the bottom of the drying chamber using an external operating lever and rotating the partition plate inside the drying chamber, so the user does not have to worry about taking out the kitchen waste. It has the advantage of saving time and effort, and has a simple structure and low cost.
