Abstract

PURPOSE:To prevent the release of the malodorous gases released from crude refuse into a room by providing a device for removing steam and malodorous gases to a discharge passage. CONSTITUTION:Part of air cools a magnetron 2 as a fan 5 operates. The remaining air is supplied from a suction port 6 into a heating treatment box 1. The steam and malodorous gases formed from the crude refuse 8 are sent through the discharge port 12 into deodorizing water 33 in a deodorizing tank (device for removing the steam and malodorous gases) 32. As a result, many small air bubbles are generated by a foaming plate 34 in the deodorizing tank 32. The bubbles ascend while coming into contact with the deodorizing water 33 and are released from a release port 35 to the outside of a shell case 13. The malodorous gases formed in this process are dissolved in the deodorizing water 33 and the gases to be released in the room are extremely minimized.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a kitchen waste processing machine for drying food waste using microwaves.

[Conventional technology]

Most of the food waste generated in households is handled by local governments who collect the waste.

Garbage collection is done two or three times a week, depending on the region, so the garbage generated every day is stored until the collection day and then collected for two or three days and sent to the collection point.

However, if food waste is stored for a long time, it becomes bulky and generates a bad odor, making it unsanitary. Disposers have traditionally been used as devices to dispose of food waste in households, but many local governments do not allow disposers to be installed because sewage treatment is incomplete and can lead to environmental pollution.

In addition, since food waste contains a high amount of moisture and is difficult to incinerate, a kitchen waste processing machine was developed in 2003 that effectively reduced the amount of food waste to ash and made it usable in the kitchen.
Since it is disclosed in Japanese Patent No. 947+5, this will be explained below.

In other words, in Fig. 6, (1) is a door-added heat treatment box housed inside the outer shell case, and (2) is a magnetron that generates microwaves.The microwaves follow the inside of the waveguide (3) and cause the above heating. It is introduced into the processing box (1) through an opening (4) provided on the back surface thereof. (5) is an internal blower, and part of the air is used to cool the magnetron (2), and the other part is supplied to the inside of the heat treatment box (1) through the intake port (6) provided on the back side. . (7) is a bottomed charging container that is stored in the heat treatment box (1) and has an open top; (8) is an exhaust port provided at the top; α1) is an exhaust fan from this exhaust port;
112 connects the heat treatment box (1) through this exhaust fan.
) An exhaust passage whose inside communicates with the outside of the outer shell case αj, 041
is the opening/closing door of the heat treatment box (1).

In the above configuration, the garbage (8) thrown into the charging container (7) is transferred to the waveguide (
3) Internal heating is performed by microwaves introduced into the heat treatment box (1) through the opening (4). As a result, the moisture contained in the food waste evaporates and is discharged to the outside of the outer case C1 through the exhaust passage 02 by the air sent from the blower (5) and the intake air by the exhaust fan σB.

In this way, the garbage becomes dry.

[Problem to be solved by the invention]

Conventional kitchen waste processing machines heat food waste as described above,
Since the moisture is evaporated, the organic components contained in the garbage are also evaporated during the drying process, resulting in a bad odor. This invention aims to solve the above problems. The purpose is to prevent bad odors caused by garbage disposal from being emitted indoors.

[Means to solve the problem]

In this invention, a device for removing water vapor and malodorous gas generated during the processing of garbage is provided in the exhaust passage, and in another invention, the malodorous gas generated is confined in a heat-resistant synthetic resin garbage bag. In yet another invention, the garbage in the input container is moved up and down during the heat treatment.

[Effect]

With this invention, the foul-smelling gas generated during the disposal of garbage is not emitted into the room.

〔Example〕

An embodiment of this invention will be described below. That is, in Figs. 1 and 2, the same parts as in the conventional one are given the same reference numerals, and redundant explanation will be omitted. It is a drum-shaped product with a bottom plate (1) and a bottom plate (3) on the other side, a large number of ventilation holes (C) on the peripheral wall, and three panfur holes (3) on the inner circumferential surface that protrude toward the center. (c) is the opening/closing lid that seals the opening eD of this input container (a); @ is the outer wall (18) of the heat treatment box (1);
) is a motor for driving the above-mentioned input container holder, which has a horizontal rotating shaft (to) which is fixed to the above-mentioned input container (A) and supported by a bearing. ) is attached to the tip of the (to) is an exhaust duct from the exhaust port Ql, and l311 is a fume pipe at the tip thereof, which forms a part of the exhaust passage 0z inside. G3 is a deodorizing tank storing deodorized water (c) in which the tip of the fumarole pipe C311 is immersed; Foam board, (c) is the deodorized water (to) in the above deodorizing tank (to)
This is a discharge port for discharging the air that has passed through the outer shell case (13).

In the above configuration, food waste (8) is introduced into the input container from its opening (2υ), the opening/closing lid 4 is fitted, and the waste is placed in the heat treatment box (1), and the container receiver is attached to the lid of the input container. (stomach)
Insert and hold the bottom part. When the power is turned on, the motor shaft rotates, microwaves are generated from the magnetron (2), and the blower (5) rotates.

As the motor handle rotates, the food waste (8) in the input container garden repeats vertical movements within the input container garden due to the action of the panfur Q4. On the other hand, the microwave is guided inside the waveguide (3) through the opening (4).

The food waste (8) in the input container (4) is irradiated, and the food waste (
8) is internally heated. This internal heating turns the moisture in the garbage (8) into water vapor, which also causes foul odors such as furin, ethane, acetaldehyde, and hydrogen sulfide.

Ammonia etc. are gasified.

On the other hand, some of the air is moved by the blower (5) to the magnetron (
2) is cooled, and a portion is passed through the heat treatment box (1) through the suction port (6).
), and the water vapor and malodorous gas generated from the garbage (8) are passed through the exhaust passage 02 to the deodorized water (
(To) Send it inside. As a result, many small bubbles are generated in the deodorizing tank by the foam board as shown in the figure. The bubbles rise while touching the deodorized water (T), and are eventually released to the outside of the outer shell case 11 through the release port G.

The above-mentioned malodorous gases generated in this process are removed from deodorized water (
The deodorized water mentioned above may be ordinary water, but it is even better if it has a deodorizing agent added to it.

Further, in the above embodiment, the garbage (8) is moved up and down in the input container garden, but this is not necessarily necessary, but it is better to move it up and down to increase the drying efficiency.

The embodiment shown in Fig. 1 above is a case where a water vapor and malodorous gas removal device consisting of a deodorizing tank is installed in the exhaust passage, but the third embodiment
The figure shows a case where a cooler is used as the above-mentioned removal device, and this will be explained below.

That is, in this Fig. 3, the same parts as those in Figs. 1 and 2 are indicated by the same symbols, and (G) is a blower for indoor air circulation installed in the middle of the exhaust passage α2, and @ is the above-mentioned blower. It was provided in the exhaust passage 02. A cooler for condensing the water vapor and foul-smelling gas that passes through it, (to) this cooler (9)
The passed air is guided into the heat treatment box (1) (circulation path, (a) is the above exhaust path σ2 and the circulation path (to) the above drain pipe for condensed water and condensed gas installed directly below this branch point. ,(
4Q is the cooling fan for the above cooler 0η.

[411 is the cooling air intake provided on the side of the outer shell case, (
42 is a cooling air outlet provided in the outer shell case (11).

With the above structure, the water vapor and foul-smelling gas generated by heating the garbage are condensed by cooling by the cooler C3'l'l installed in the exhaust passage, and then passed through the drain pipe (toward) to the outer shell case. Excreted outside the bath.

The air is returned to the heat treatment box (1) through the circulation path.

As described above, the food waste (8) is dried while removing water vapor and foul-smelling gas generated from the food waste (8). Other operations are similar to those in FIGS. 1 and 2.

Although an air-cooled heat exchanger is used as the cooler in the above embodiment, the present invention is not limited to this, and for example, cold water may be sprayed directly onto the exhaust passage.

Figures 4 and 5 show still other embodiments of the present invention, and the same parts as in Figure 3 are given the same reference numerals. This is a garbage bag for storing food waste (8) to be thrown in, and it is made of a film made of, for example, urethane-based synthetic resin, and has many pores on the micron order on its entire surface, and these pores are Specifically, it is characterized by a size that allows water vapor to pass through, but does not allow particles larger than 2 water vapor, such as foul-smelling gas, to pass through.

That is, in the above case, as shown in Fig. 5, put the food waste (8) into a garbage bag (43), tie the inlet with a string (44), and put the whole thing into the container (A) through its opening CD. After that, fit the opening/closing lid (a) into this opening 121), put the input container handle into which the garbage bag (43 is inserted) into the heat treatment box (1), and place the container receiver into the handle. The bottom part (2) is inserted and held, and then the garbage inside the garbage bag (43) is internally heated using microwaves in the same manner as above.

Due to this internal heating, butane, ethane, acetaldehyde, which causes water vapor and bad odor, is extracted from the garbage (8).
Foul-smelling gases such as hydrogen sulfide and ammonia are generated.

However, in the case of this invention, the above-mentioned garbage bag (43) does not allow particles larger than water vapor to pass through, so the particles of the above-mentioned malodorous gas produced above, excluding ammonia, are more likely to be absorbed than water vapor. The ammonia, which is confined within C3 and is not released outside the outer shell case, and in particular has smaller particles than water vapor, is appropriately discharged outside the outer shell case in a state dissolved in the condensed water.

In the above example, the food waste is moved up and down by the rotation of the input container while irradiating microwaves to improve drying efficiency. Although it is not necessarily necessary to rotate the input container, it is better to rotate the garbage. Even better.

〔Effect of the invention〕

Since the kitchen waste disposal machine of the present invention is configured as described above, when the foul-smelling gas generated from the food waste is released into the room, the food waste is dried.

This has the effect of reducing its bulk and making it easier to dispose of.
