  By the way, in the garbage processing apparatus having the exhaust means as described above, when the deodorized air is discharged to the outside, an operating noise of the blower, a wind noise generated in the exhaust path, and the like are generated as exhaust noise. In particular, since the drying type garbage processing apparatus requires a large capacity blower, the level of exhaust noise is higher than that of other types of garbage processing apparatuses.

  In the above-described garbage processing apparatus and the deodorizer for the garbage processing apparatus, the deodorizer itself has a silencing mechanism for reducing exhaust noise in the process of passing the air to be deodorized. Thus, it is possible to reduce the size of the garbage processing apparatus without securing the space.

  According to the present invention, by providing the deodorizer with a silencing function, it is possible to contribute to the downsizing of the apparatus and the garbage processing apparatus that can reduce the size of the apparatus without securing the space as in the case of installing the silencer individually.

  The blower 32 has a cylindrical case (not shown) provided with an inlet and an outlet (both not shown), and a motor and a fan (both not shown) provided in the case. The inlet of the case is connected to the exhaust port 21c of the processing tank 21, and the outlet is connected to the inlet 33a1 (see FIG. 4) of the first passage PA1 of the heat exchanger 33 via the pipe P1.

  As shown in FIG. 4, the heat exchanger 33 has an outer case 33a and an inner case 33b formed of metal or the like. The outer case 33a is provided with an inlet 33a1 and an outlet 33a2, and the inner case 33b is provided with an inlet 33b1 and an outlet 33b2. Further, a heat radiating fin 33b3 is provided on the outer surface of the inner case 33b. The outer case 33a covers the entire inner case 33b so that only the inlet 33b1 and the outlet 33b2 are exposed, and the space formed between the outer case 33a and the inner case 33b covers the inner case 33b, the inlet 33b1 and the outlet 33b2. The first passage PA1 has a surrounding shape, and the inlet 33a1 and the outlet 33a2 are the inlet and the outlet of the first passage PA1.

This heat exchanger serves to transmit the heat of the deodorized air flowing in the direction of the arrow in the second passage PA2 to the air before the deodorization flowing in the direction of the arrow in the first passage PA1.

  As shown in FIG. 5, the deodorizer 34 has a rectangular cylindrical inner case 34a and an outer case 34b formed of metal or the like. A cylindrical inlet 34a1 is provided at one end in the longitudinal direction of the inner case 34a, and a cylindrical outlet 34a2 is provided at the other end in the longitudinal direction. The outer case 34b covers the entire inner case 34a so that only the inlet 34a1 and the outlet 34a2 are exposed, and the space formed between the inner case 34a and the outer case 34b covers the inner case 34a, the inlet 34a1 and the outlet 34a2. It is a heat insulating space HIS with a surrounding shape. The inner space of the inner case 34a is divided into a first chamber CH1 on the inlet side and a second chamber CH2 on the outlet side by a partition plate 34a3, and the partition plate 34a3 has a cylindrical communication port facing the inlet 34a1. 34a4 is provided. That is, the deodorizer 34 has a structure including a two-stage expansion type silencing mechanism in which each of the first chamber CH1 and the second chamber CH2 on both sides of the partition plate 34a3 is a silencing expansion chamber. Furthermore, an electric heater 34c and a catalyst device 34d are provided in the second chamber CH2 of the inner case 34a.

  As the electric heater 34c, a heater that can heat the air before being sent to the catalyst 34d without suppressing the passage of air, for example, a rod heater that is formed in a spiral shape is preferably used. The electric heater 34c is disposed between the partition plate 34a3 and the catalyst device 34d. The catalyst device 34d has a holder and a honeycomb-shaped catalyst support portion (both not shown) provided in the holder. As the catalyst supported on the catalyst supporting part, a catalyst that promotes oxidative decomposition of odor components contained in the air to be deodorized for odor removal, preferably a platinum-based high-temperature oxidation catalyst or the like is used. The catalyst unit 34d is arranged so that the outlet side thereof faces the outlet 34a2 of the inner case 34a.

  The deodorizer 34 heats the air before deodorization flowing in the direction of the arrow in the inner case 34a, and oxidizes and decomposes odor components contained in the air in the process of the heated air passing through the catalyst 34d. Play the role of removing. In addition, the deodorizer 34 uses a two-stage expansion type silencing mechanism incorporated in the deodorizer 34 to remove exhaust noise generated by operating noise of the blower 32 and wind noise generated in the exhaust path leading to the deodorizer 34. It plays the role of reducing using the reflection interference effect of the sound wave depending on each expansion chamber (CH1, CH2).

  Next, functions of the above-described garbage processing apparatus will be described.

  The above-described garbage processing apparatus has at least a processing mode and a discharge mode as operation modes.

  When the processing target garbage FW is dried and pulverized, the processing mode is switched to the processing mode, and then the processing target garbage FW and a predetermined amount of liquid adjustment material (rice bran, bran, etc.) are processed through the inlet 21a. The operation start switch is turned on after closing the first open / close lid 15 into the tank 21. As a result, the processing target garbage FW and the liquid component adjusting material charged into the processing tank 21 are heated to a predetermined temperature by the heater 25b of the heater 25, and the counterclockwise direction of each blade 24c of the stirrer 24 is set. Is stirred by rotation of The heating and stirring are continued for a predetermined time. As a result, moisture and oil contained in the processing target garbage FW are absorbed by the liquid component adjusting material, and the processing target garbage FW is sufficiently dried and dried. The processing target garbage FW is powdered by stirring.

  In this processing mode, the air in the processing tank 21 is taken into the deodorizer 34 through the first passage AP1 of the heat exchanger 33 by the operation of the blower 32, and the taken-in air is brought to a predetermined temperature by the electric heater 34c. In the process in which the heated air passes through the catalyst 34d, the oxidative decomposition of the odor component contained in the air is promoted to remove the odor, and the deodorized air becomes the second passage AP2 of the heat exchanger 33. And discharged to the outside through the exhaust port 35. In the process in which the air to be deodorized passes through the deodorizer 34, the two-stage expansion type silencing mechanism provided in the deodorizer 34 is caused by operating noise of the blower 32, wind noise generated in the exhaust path to the deodorizer 34, and the like. Exhaust noise is reduced.

FIG. 7 shows the transmission loss characteristic (noise reduction performance characteristic) of the noise reduction mechanism provided in the deodorizer 34. As an example, the characteristics shown in the figure have a cross-sectional area of 0.0023 m ² for each of the inlet 34a1, the communication port 34a4 and the outlet 34a2, and a cross-sectional area of each of the first and second chambers CH1 and CH2 is 0.0143m ^2. The effective length of the first and second chambers CH1 and CH2 is 0.23 m, and the noise frequency f11 of the blower 32 with a commercial power supply of 50 Hz is 441 Hz (the second harmonic frequency f21 is 882 Hz) and the commercial frequency is 60 Hz. The noise frequency f12 at the power source is 531 Hz (the second harmonic frequency f22 is 1062 Hz). As can be seen from the figure, the deodorizer 34 based on the above specification can obtain a transmission loss (silence performance) of about 32 dB at the frequencies f11 and f12, and the same transmission at the second harmonic frequencies f21 and f22. Loss (silence performance) can be obtained.

  By the way, when the deodorizer 34 based on the above specifications is mounted on the garbage disposal device and the actual exhaust noise level (noise level) is measured with a commercially available sound level meter, a deodorizer without a silencing mechanism is installed. In comparison, the noise level could be reduced by about 6.5 dB with a 50 Hz commercial power supply, and the noise level could be reduced by about 4.2 dB with a 60 Hz commercial power supply. In addition, it was confirmed that the same effect can be obtained even when the effective length of the first and second chambers CH1 and CH2 in the specification is 0.5 m. Needless to say, the same effect can be obtained by appropriately changing the cross-sectional area and the effective length according to the target noise frequency.

  On the other hand, when discharging the processed product, the operation start switch is turned on after opening the second opening / closing lid 22 after switching the operation mode to the discharge mode. As a result, each blade 24c of the agitator 24 rotates clockwise for a predetermined time, and the processed product in the processing tank 21 is moved toward the discharge port 21b by the rotation, and the inclined chute 23a is moved from the discharge port 21b. And is collected in a container (not shown) disposed below the front end through the inclined chute 23a.

  As described above, since the deodorizer 34 itself has a silencing mechanism for reducing exhaust noise in the process of passing the deodorizing target air, it is not necessary to secure a space as in the case where the silencer is individually installed. There is an advantage that the waste disposal apparatus can be downsized.

  Further, since the silencing mechanism constitutes a two-stage expansion type silencing mechanism in which each of the two chambers CH1 and CH2 serves as a silencing expansion chamber, the exhaust noise is effectively reduced by the silencing action by the two-stage expansion. There are advantages you can do.

  Further, the silencing mechanism can be constructed by providing a part of the mechanism that is also used as a part of the deodorizer 34 and by simply providing a partition plate 34a3 with a communication port 34a4 in the inner case 34a. Compared to the case where a silencer is prepared and installed separately, there is an advantage that it is economical and economical.

  Further, since the deodorizer 34 has a structure in which a heat insulating space HIS is provided between the inner case 34a and the outer case 34b, the inner case 34a is heated when the air to be deodorized is heated by the electric heater 34c. Even when heated, the heat can be prevented from leaking outside from the outer case 34b, and an expensive heat insulating material is unnecessary, which is economical.

  FIG. 8 is a longitudinal sectional view of a deodorizer showing a first modification of the deodorizer 34.

  The deodorizing machine 34 'shown in the figure is a partial modification of the deodorizing machine 34. The difference from the deodorizing machine 34 is that a circular communication port 34a6 is used instead of the partition plate 34a3 and the communication hole 34a4. The partition plate 34a5 is used. The effect obtained when this deodorizer 34 ′ is used instead of the deodorizer 34 is the same as when the deodorizer 34 is used.

  FIG. 9 is a longitudinal sectional view of a deodorizer showing a second modification of the deodorizer 34.

  The deodorizer 36 shown in the figure has a rectangular cylindrical inner case 36a and an outer case 36b made of metal or the like. A cylindrical inlet 36a1 is provided at one longitudinal end of the inner case 36a, and a cylindrical outlet 36a2 is provided at the other longitudinal end. The outer case 36b covers the entire inner case 36a so that only the inlet 36a1 and the outlet 36a2 are exposed, and the space formed between the inner case 36a and the outer case 36b has a shape surrounding the inner case 36a and the inlet 36a1. It is a resonance space SRS. The inlet 36a1 of the inner case 36a is provided with at least one hole 36a3 (two in the drawing) communicating with the resonance space SRS. That is, the deodorizer 36 has a structure including a Helmholtz-type silencer mechanism having a silencer resonance space SRS between the inner case 36a and the outer case 36b. Further, an electric heater 36 and a catalyst device 36d are provided in the inner case 36a.

  As the electric heater 36c, a heater that can heat the air before being sent to the catalyst device 36d without suppressing the passage of air, for example, a rod heater that is formed in a spiral shape, is preferably used. The electric heater 36c is disposed between the inlet 36a1 and the catalyst device 36d. The catalyst device 36d includes a holder and a honeycomb-shaped catalyst support portion (both not shown) provided in the holder. As the catalyst supported on the catalyst supporting part, a catalyst that promotes oxidative decomposition of odor components contained in the air to be deodorized for odor removal, preferably a platinum-based high-temperature oxidation catalyst or the like is used. The catalyst unit 36d is arranged so that the outlet side thereof faces the outlet 36a2 of the inner case 36a.

  The deodorizer 36 heats the air AIR1 before deodorization flowing in the direction of the arrow in the inner case 36a, and oxidizes and decomposes odor components contained in the air in the process of the heated air passing through the catalyst device 36d. Plays the role of removing. Further, the deodorizer 36 uses a Helmholtz-type silencer incorporated in the deodorizer 36, and the sound wave SOU1 of the exhaust noise generated by the operating sound of the blower 32, the wind noise generated in the exhaust path leading to the deodorizer 36, and the like. , SOU2 is reduced by using the resonance action in the silencing resonance space SRS.

  The deodorizer 36 can obtain the same deodorizing function as that of the deodorizer 34, and can obtain the same silencing effect as the deodorizer 34 although the deodorizing principle is different. That is, in the processing mode, the air in the processing tank 21 is taken into the deodorizer 36 through the first passage AP1 of the heat exchanger 33 by the operation of the blower 32, and the taken-in air is heated to a predetermined temperature by the electric heater 36c. In the process in which the heated air passes through the catalyst 36d, the oxidative decomposition of the odor component contained in the air is promoted to remove the odor, and the deodorized air becomes the second passage AP2 of the heat exchanger 33 and It is discharged to the outside through the exhaust port 35. In the process in which the air to be deodorized passes through the deodorizer 36, exhaust noise generated by operating noise of the blower 32, wind noise generated in the exhaust path to the deodorizer 36, etc., by a Helmholtz type silencer mechanism provided in the deodorizer 36. Is reduced.

  The effect obtained when the deodorizer 36 is used instead of the deodorizer 34 is basically the same as that when the deodorizer 34 is used, but the role of the heat insulating space HIS is different from that of the inner case 36a. The resonance space SRS provided between the case 36b and the case 36b is responsible. That is, since the resonance space SRS provided between the inner case 36a and the outer case 36b serves as the heat insulating space HIS, there is an advantage that it is not necessary to provide a space dedicated for heat insulation.

  In the embodiment described above, the rectangular cylindrical inner cases 34a, 36a and the outer cases 34b, 36b are shown as the deodorizers 34, 34 ', 36. However, the inner cases 34a, 36a and the outer cases 34b, 36b are cylindrical. The same effect as described above can be obtained even in the case of the shape.

  In the above-described embodiment, the deodorizers 34 and 34 'are provided with the heat insulating space HIS having a shape surrounding the inner case 34a, the inlet 34a1 and the outlet 34a2 between the inner case 34a and the outer case 34b. The heat insulating space may be formed so as to surround only the peripheral surface of the inner case 34a by closely contacting the end surfaces of both cases.
