2. Description of the Related Art Conventionally, a garbage disposal apparatus having means for deodorizing odors generated from a decomposition tank is disclosed in Japanese Unexamined Patent Publication No. 7-2.
Japanese Patent Application Laid-Open No. 65841/1994 proposes a device described in Japanese Patent Application Laid-Open No. 65841/1994. In this method, the odor (atmospheric gas) generated during the decomposition process from the decomposition tank (garbage disposal tank) is introduced into the water tank (liquid storage container) and bubbled, and the odor after bubbling is returned to the decomposition tank. It is a garbage disposal device. Thereby, deodorization is performed without releasing odor to the outside.

[0003]

However, according to the study of the present inventor, in the above-mentioned garbage disposal apparatus, impurities in the odor are dissolved in water by bubbling to deodorize the garbage. It has been found that the water in the water tank evaporates little by little due to heat or the like, so that it is necessary to supply water to the water tank. In particular, the odor generated during the decomposition treatment is generally hot and humid and raises the water temperature in the water tank, so that the water in the water tank is likely to evaporate.

[0004] For this reason, for example, a water supply work for replenishing a shortage of water is required, which causes a problem that a place where the garbage disposal apparatus is installed is restricted. In view of the above, the present invention relates to a garbage disposal apparatus having a means for dissolving odor generated from a decomposition tank in water in a water tank and deodorizing the odor,
It is an object of the present invention to suppress evaporation of water in a water tank and eliminate the need for replenishing water.

Accordingly, the water in the water tank (4) is cooled by the cooling means (8, 9), so that evaporation of the water is suppressed, and it is not necessary to supply water. Most of the impurities in the odor generated during the decomposition treatment of garbage, such as ammonia and hydrogen sulfide, are water-soluble, and dissolving these impurities in water is specifically performed in the water tank (4). This can be achieved by bubbling an odor into the water.

[0007] The cooling means (8, 9) is, specifically, a pipe line (8) capable of exchanging heat between water flowing therein and air in the atmosphere as in the invention of claim 2; This pipeline (8)
And a circulating means (9) for circulating the water in the water tank (4). In particular, as described above, the odor is generally hot and humid, and the water temperature in the water tank (4) tends to be high. Therefore, the odor can be effectively cooled by heat exchange with air in the atmosphere.

According to the third aspect of the present invention, the pipe (8) is provided with ozone mixing means (10, 11) for mixing ozone with water in the pipe (8). And ozone dissolution is performed in the pipeline (8). Thereby, the water in the water tank (4) is cooled by circulating in the pipe (8), and the odor component contained in the water can be ozone-sterilized. Therefore, the water in the water tank (4) can always be maintained in a regenerated state, and efficient deodorization can be realized.

A plurality of holes 6 are formed in one end side opening 5a of the introduction pipe 5, and the odor discharged from the decomposition tank 2 into the water tank 4 is bubbled, and impurities (odor components, moisture, etc.) in the odor are discharged. ) Is easily dissolved in water. Therefore, the introduction pipe 5 is configured as a bubbling discharge pipe.

An air outlet 61 is provided at a position above the water surface on the side wall of the water tank 4. further,
One end of a discharge pipe 62 for returning the air deodorized in the water tank 4 to the decomposition tank 2 is connected to the air discharge port 61,

A branch discharge pipe 62a branches from an intermediate portion of the discharge pipe 62, and is provided so as to open to the outside air. With the branch discharge pipe 62a, the outside air introduced from the outside air inlet 25 flows from the decomposition tank 2 to the purification chamber 4 and the water tank 6, and a part of the air (deodorized air) from the water tank 6 is discharged to the outside. (In the atmosphere). Therefore, the air in the decomposition tank 2 is partially ventilated.

Reference numeral 63 denotes a drain pipe communicating with the inside of the water tank 4 on the side wall of the water tank 4, and is provided with an open / close valve (not shown) so that the water in the water tank 4 can be discharged as required. . Here, the pipe 8 is provided through the wall surface of the water tank 4 so that the openings at both ends are located in the water of the water tank 4 and the middle part is located outside the water tank 4, that is, in the atmosphere. . The conduit 8 is made of, for example, a metal having good thermal conductivity, and constitutes a heat exchange section 8a whose middle part located in the atmosphere has a meandering shape as shown in the figure.

The atmosphere includes not only the outdoor air but also, for example, when the garbage disposal apparatus is installed in a cooking place or the like, the air in the room. It means the space outside the container 1 of the garbage processing apparatus A.
Therefore, the temperature of the air in the atmosphere is lower than the temperature of the high-temperature and high-humidity odor generated during the garbage decomposition treatment from the decomposition tank 2.

In the middle of the pipe 8, an electric wall is provided.
The pump 9 (circulation means) is interposed and set. Then, by the operation of the water pump 9, the water in the water tank 4 is circulated such that the water is sucked up, flows through the pipeline 8 and returns to the water tank 4. The water flowing through the pipe 8 can exchange heat with air in the atmosphere at a heat exchange section 8a disposed in the atmosphere. Therefore, the water in the water tank 4 whose temperature has risen due to bubbling or dissolution of the odor is cooled by heat exchange with the atmosphere in the heat exchange unit 8a.

Is configured to operate constantly when power is supplied from the power supply to the garbage disposal apparatus A, that is, for example, when an outlet is plugged in. Next, the operation of the present embodiment will be described. First, the basic operation of the garbage decomposition process in the garbage processing apparatus A will be described.

When garbage is put into the disintegrating tank 2 from the inlet 3 and an electric motor (not shown) is turned on, the stirring members 24 in each of the dissolving tanks 20 and 21 rotate to disassemble the garbage. Processing is performed. Here, as described above, since the fan 7 is operating, the high-temperature and high-humidity odor generated in the decomposition process is:
It is deodorized by the deodorizing means 100 and returns to the decomposition tank 2. The rotation of the stirring member 24 continues for a predetermined time, and ends when the electric motor is turned off by a manual switch or a timer unit of the control unit. Thereafter, the microorganism carrier 23 mixed with the garbage in the decomposition tank 2 reacts to perform a decomposition treatment.

Next, the operation of the deodorizing means 100 will be described. As described above, the air cleaning means 100 includes the garbage disposal apparatus A.
If the power is supplied from the power supply, the power supply operates constantly. Therefore, there is a flow of air circulating in the order of the decomposition tank 2, the water tank 4, and the decomposition tank 2, and a flow of water circulating in the order of the water tank 4, the pipeline 8, and the water tank 4. During the above-mentioned garbage decomposition treatment, the high-temperature and high-humidity odor generated from the decomposition tank 2 flows through the introduction pipe 5 by the fan 7 and is bubbled into the water tank 4 by the action of the plurality of holes 6. The bubbling odor component in the odor is dissolved in water, and the moisture in the odor becomes condensed water and is combined with the water in the water tank 4. Thus, the odor is purified (deodorized) and dehumidified, and the purified and dehumidified air returns from the water tank 6 to the decomposition tank 2 through the discharge pipe 62, and a part of the air is branched and discharged.
Is discharged from

Here, the temperature of the water in the water tank 4 rises due to the contact with the high-temperature and high-humidity odor and the heat of dissolution of the odor component.
However, the water in the water tank 4 flows through the pipeline 8, dissolves and sterilizes the ozone from the ozone mixing means (10, 11), and cools by flowing through the heat exchange section 8a to exchange heat with the atmosphere. Is returned to the water tank 4, so that the rise in water temperature of the water tank 4 can be suppressed.

As described above, according to the present embodiment, the water tank 4
Since the water inside is cooled by the cooling means (8, 9), evaporation of the water is suppressed, and it is not necessary to supply water. Further, even if some evaporation occurs, there is no problem because the condensed water from the high-temperature and high-humidity odor is added to the water in the water tank 4. Further, according to the present embodiment, the water in the water tank 4 flows through the pipe 8 and is dissolved in ozone, so that the odor components contained therein can be ozone-sterilized. Therefore, the water in the water tank 4 can always be maintained in a regenerated state, and efficient deodorization can be realized.

Therefore, according to the present embodiment, it is possible to provide a garbage disposal apparatus A having a deodorizing means 100 for efficiently deodorizing with little water without replenishing water for a long period of time. The garbage disposal apparatus A can be freely installed without any restrictions such as the necessity of waterworks. Further, according to the present embodiment, the high-temperature and high-humidity odor generated during the processing of garbage is deodorized and dehumidified. Secondly, it is possible to prevent the water from accumulating as sewage and degrading the decomposition ability.

Further, according to the present embodiment, the water in the water tank 4 can be cooled by the air in the atmosphere only by providing the heat exchange section 8a, which is a part of the pipe 8, in the atmosphere. This eliminates the need for a separate cooling means such as a separate refrigeration cycle or the like, and can reduce the size and simplification of the deodorizing means 100 itself and the entire garbage disposal apparatus A. (Other Embodiments) The shape, configuration, and the like of the heat exchange unit provided in the middle of the pipe 8 are not limited to those that exchange heat with the atmosphere in the meandering pipe, and the refrigerant ( Cooling using cooling water or the like. Further, in the deodorizing means 100, the pipe line 8 may be forcibly air-cooled by a fan (a ventilation means) or the like.

Further, dissolving the impurities in the odor in water is not limited to the above-described bubbling method. For example, a spray nozzle may be provided on the water return side of the pipe 8 to introduce the odor into the space above the water surface of the water tank. Water may be sprayed on the introduced odor and deodorized by a water mist. In this case, the pipe 8 is provided with the ozone mixing means as described above, and the water storage portion of the water tank 4 functions as a water tank.

Although it is necessary to replace water in the water tank 4 due to dirt, the ozone mixing means 10 and 11 may not be provided.
