Abstract

PURPOSE:To perform work safely by eliminating a ground matter combustion process and to prevent the generation of an offensive smell by receiving the ground matter of garbage ground in a disposer in a dehydration basket and removing moisture by the centrifugal force of the dehydration basket and subsequently feeding the ground matter to a drying chamber to dehumidify and dry the same. CONSTITUTION:The garbage charged in the grinding tank 3 of a disposer 2 along with water is ground by a rotary blade 4 to flow in a rotary dehydration basket 6 through a drain pipe 16. The ground matter is centrifugally dehydrated herein and water is drained from a drain port 1b while the ground matter falls on the receiving plate 25 of a drying chamber 23 from a discharge port 1a. A compressor 19 and a blower 22 are driven in the drying chamber 23 to perform dehumidifying and drying operation and the ground matter on the receiving plate 25 is gradually dried to fall in a dust container 27. Since trap parts 16a, 1c are provided to a drain route, the rising of an offensive smell is prevented. Since a dehumidifier due to a cooling medium is used, the exhaustion to the outside is unnecessary and there is no possibility such that the offensive smell in the drying chamber is leaked to the outside.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for processing kitchen waste crushed by a disposer.

[Prior Art] FIG. 4 is a longitudinal sectional view showing a conventional kitchen waste processing apparatus disclosed in, for example, Japanese Patent Application Laid-open No. 190663/1983.

In the figure, (1) is a box, which has a discharge port (la) at the top and a drain port (1b) at the bottom. (2) is a disposer provided in the box body (1), and the input port (3a
), a rotary blade (4) disposed in the crushing tank (3), and a motor (5) for driving the rotary blade (4). (6) is a dewatering basket driven by a motor (5), which extends upward and has small holes (6a) in its side and bottom surfaces. (7) is a box (1
) is located adjacent to the combustion chamber and has an open discharge port (1a), (8) is a loss drum provided at the lower part of the combustion chamber (7),
(9) is a heating element for ignition made of silicon carbide provided on the Rosdol (8), and (10) is a box for the ash tray placed at the bottom of the Rosdol (8).

Conventional kitchen waste processing equipment is configured as described above, with an input port (
When the kitchen waste is put into the crushing tank (3) along with water from step 3a) and the motor (5) is rotated, the kitchen waste is crushed by the rotating blade (4) and falls into the dewatering basket (6). Dehydration basket (6)
is rotated by the motor (5), the fallen kitchen waste is squeezed by the centrifugal force of the dewatering basket (6), the water flows out through the small hole (6a), and is drained from the drain port (Ib) to the sewer pipe (
(not shown).

On the other hand, the squeezed pulverized material is similarly transported upward by the centrifugal force and falls from the discharge port (1a) onto the loss dollar (8) of the combustion chamber (7). Here, although the details are omitted, microwaves are generated from a microwave generator (not shown), thereby heating the crushed material on the Rosdol (8),
The water is evaporated and dried. When the crushed material dries,
The ignition heating element (9) is heated by absorbing the microwave,
When heated to red heat, the crushed material is ignited and burns to ash. Since this ash falls into the ash receiver box (10), it can be pulled out and thrown away at the appropriate time. In this way, it is possible to store kitchen waste in an odorless state without discharging the pulverized material into the sewerage system.

[Problems to be Solved by the Invention] In the conventional kitchen waste processing device as described in 11-1, the kitchen waste is crushed in the disposer (2), centrifugally dehydrated, and then burnt for disposal. The problem is that it is not safe enough to be installed under. Another problem is that odor is generated during combustion.

The present invention was made to solve the above problems, and an object of the present invention is to provide a kitchen waste processing device that allows safe operation without combustion and prevents the generation of odors.

[Means for Solving the Problems] The kitchen waste processing apparatus according to the present invention stores the crushed kitchen waste crushed by a disposer in a dehydration basket, dehydrates water by the centrifugal force of the dehydration basket, and dehydrates the crushed garbage. The pulverized material is transported to a drying room, where it is dehumidified and dried using a dehumidifying device.

[Function: In this invention, the pulverized kitchen waste is transported to the drying chamber and dehumidified and dried, so there is no step of burning the pulverized material, and no odor is generated due to combustion.]

Now, suppose that the user puts kitchen waste together with water into the crushing tank (3) through the inlet (3a) and turns on the power switch (35).

First, in step (41) it is determined whether the power switch (35) is turned on.
Since the disposer (2) is operated in step (42), the kitchen waste is crushed by the rotary blade (4). When the water rises to a predetermined water level, the siphon part (
], 6b) causes the crushed material and water to flow into the dewatering basket (6) through the drain pipe (16). The motor (17) is activated simultaneously with the operation of the disposer (2), and the dewatering basket (6) is activated.
) rotates, centrifugally dehydrates as described above, and the water drains through the drain port (
1b). In addition, the pulverized material is similarly transported upward by centrifugal force, and is transported from the discharge port (1a) to the drying chamber (2).
The receiver of 3) falls onto the plate (25).

Furthermore, the compressor (19) and the blower (22) are driven,
The dehumidifying and drying operation is started, and the inside of the drying room (23) is dehumidified.
, to be dried.

Next, in step (43), it is determined whether 30 minutes have passed since the start of the dehumidifying drying operation, and if it is within 30 minutes, return to step (41) and repeat steps (4]) to (43). . During the execution of steps (41) to (43),
When the process by the user's disposer (2) is completed and the power switch (35) is shut off, step (41)
The process then proceeds to step (44), where the operations of the disposer (2) and dewatering basket (6) are stopped, but the dehumidifying and drying operation is continued, and the crushed material on the receiving plate (25) is gradually dried.

When it is determined in step (43) that 30 minutes have passed since the start of the dehumidifying and drying operation, the output of the temperature difference detector (31) is inputted in step (45), and the temperature T of the drying chamber (23) is determined.
It is determined whether the temperature T2 and the temperature T2 below are almost equal. That is, T2>T during dehumidifying and drying operation.

When the drying is completed, the time becomes T24T1, so it is determined that the drying is completed. Since T1=T2 immediately after the start of operation, the temperature difference is detected 30 minutes after the start of the dehumidifying and drying operation.

When it is determined that the drying is completed in step (46), the motor (26) is driven in step (47) to vibrate the receiving plate (25) for 10 seconds, and the dried pulverized material is placed in the garbage container (27).
The entire process is completed.

In addition, since the drainage path is provided with a trap section (16a) (lc), odor is prevented from rising.

The disposal of garbage by the disposer (2) can be carried out freely at any time even during the dehumidifying and drying operation. Further, since the dehumidifying and drying operation uses a dehumidifying device using a refrigerant, there is no need for exhaust to the outside, and there is no risk of odor inside the drying chamber (23) leaking out of the box.

In addition, in the example, a dehumidification device using a compressor (■9), a condenser (20), and an evaporator (2 units) was used.
Other types of dehumidification devices may be used, for example, a dehumidification device using an electronic cooling element that utilizes the Peltier effect.

[Effects of the Invention] As explained above, in this invention, the pulverized kitchen waste that has been pulverized by the disposer is stored in a dehydration basket, and the water is dehydrated by the centrifugal force of the dehydration basket, and the pulverized material is transported to the drying room. Since dehumidifying and drying is performed here, there is no step of burning the crushed material, which makes it possible to work safely and to prevent the generation of odors.
