After a lapse of a predetermined time after the start of the energization, the microcomputer 98 starts the operation of other devices when the deodorizing heater 59 becomes capable of heating the temperature of the passing air to around + 350 ° C. as described above. .

Then, when the kitchen waste generated in the sink 2 is thrown into the kitchen discharge hole 13 together with the running water, the kitchen waste is crushed by the disposer 16 and discharged into the kitchen introducing hose 17 together with the running water. In this way, when the garbage (solid-liquid separation object) crushed from the disposer 16 from the garbage introducing hose 17 is conveyed into the solid-liquid separation filter 83 of the solid-liquid separation device 29, the liquid content is small holes 83B. .. from the solid-liquid separation filter 83, and is discharged to the outside from the drain port 81D. Therefore, only the solid content of kitchen waste remains in the solid-liquid separation filter 83. On the other hand, the microcomputer 98 drives the solid-liquid separation motor 29M to rotate the rotary shaft 8
4, the spiral 86 is rotated in a fixed direction.

By the rotation of the spiral 86, the solid content of the garbage in the solid-liquid separation filter 83 is carried out toward the carry-out port 93 at the front end. At this time, the kitchen waste is subjected to a pressing action, so that the liquid component contained in the kitchen waste is satisfactorily discharged and separated. Further, the arm 92 also rotates together with the spiral 86, and the spiral 8
The solid content of the kitchen waste that is conveyed by the 6 toward the outlet 93 and pressed against the cap 82 is the inlet 93B of the outlet 93.
I will guide you in the direction. Thereby, the solid-liquid separation filter 8
The solid content of the garbage that has been solid-liquid separated in 3 is smoothly fed to the carry-out port 93.

At this time, since the carry-out port 93 is located above the rotary shaft 84 and the drain port 81D is formed on the lower surface of the outer shell 81, even if a large amount of water flows in at the beginning of operation, the carry-out port 93 is provided.
Will not overflow. Also, the cleaning rods 89, 89
Rotates on the outer surface of the solid-liquid separation filter 83, so that the small holes 8
The kitchen waste that has jumped out of 3B ... Is scraped off, the solid content can be conveyed smoothly, and dirt on the outer surface of the solid-liquid separation filter 83 can be removed. Further, since the carry-out port 93 is gradually expanded toward the exit 93A, it is possible to avoid the inconvenience that the solid content of kitchen waste is clogged in the carry-out port 93.

The solid content of the garbage separated in this way by the solid-liquid separation device 29 is introduced from the outlet 93A of the carry-out outlet 93 into the drying tank 4. Then, for example, the garbage is accumulated up to a predetermined position lower than the cleaning member 41 (the amount of the garbage to be introduced may be larger, and at least the cleaning member 41 should be above the height of the dried garbage). By the way, the microcomputer 98 stops the solid-liquid separation motor 29M and starts the operation of the stirring motor 28 automatically or based on the automatic operation or the manual operation, and the drying chamber heater 24
Power supply to each fan motor 23M, 76M
And start operation of 77M. In addition, these stirring motors 2
8, drying chamber heater 24, fan motors 23M, 76M,
The operation of 77M may be started from the time when the kitchen waste is introduced into the drying tank 4 from the solid-liquid separation device 29.

As a result, the kitchen waste (solid content) in the drying tank 4
Is stirred by being stirred counterclockwise in FIG. 6 by the stirring member 38B of the stirring device 38. At this time, the kitchen waste is pushed up by the stirring member 38B on the right side toward the right side. However, since there is the eaves section 42, the kitchen room that is pushed up and raised can change the moving direction inward by the eaves section 42, and further,
Before it reaches the cover 44, it falls inside the drying tank 4.

Further, in this case, since the eaves portion 42 is highly inclined inward, the corners below the eaves portion 42 formed by the eaves portion 42 and the side surface 4A of the drying tank 4 are obtuse angles. Therefore, the inconvenience that the garbage pushed up by the stirring member 38B is trapped in the corners and stays does not occur, and the garbage smoothly drops into the drying tank 4. With these, the drying tank 4 can be formed without increasing the height of the drying tank 4.
It is possible to prevent the garbage from being scattered from the kitchen.

Here, when the kitchen waste has a large amount of starch, it becomes stuck in a rice cake shape on the inner surfaces of the stirring device 38 and the drying tank 4, but the rotating arms 38A and 38A of the stirring device 38 are As described above, the front and rear surfaces 4C, 4 of the drying tank 4
Since it is sufficiently separated from D, it is difficult to form a garbage bridge between the rotary arm 38A and the inner surface of the drying tank 4. Further, since the stirring member 38B comes close to the cleaning member 41 in the ascending process, even if the garbage becomes a rice cake-like substance and adheres to the stirring member 38B, it is scraped off by the cleaning member 41.

As a result, regardless of the contents of the kitchen waste, the stirring device 38 can smoothly rotate and exert a stirring action. Further, the cleaning member 41 is placed at a position higher than the height of the dry kitchen waste as described above, and the stirring device 3
8 is provided at a position where it does not interfere with the cleaning member 4
1 does not adversely affect the stirring of kitchen waste by the stirring device 38.

On the side where the stirring device 38 rotates from the lowermost portion of the bottom surface 4B of the drying tank 4 and the stirring member 38B descends (on the left side of the rotation shaft 37 in FIG. 6), the stirring member 38 is provided.
Since B approaches the drying tank 4 while descending and compresses the solid content of the garbage, at the height near the rotating shaft 37, the garbage is less likely to be clogged between the drying tank 4 and the stirring member 38B, and the bottom surface 4B The garbage will be crushed near the bottom of the. On the other hand, on the side where the stirring device 38 rotates and the stirring member 38B rises, this time the stirring member 38B rises and the drying tank 4
Therefore, the kitchen waste that is sandwiched between the drying tank 4 and the stirring member 38B after passing through the lowermost part also falls smoothly.

As a result, the stirring device 38 can effectively and smoothly stir the kitchen waste in the drying tank 4. Further, since the rotating diameter of the stirring device 38 is relatively small and the height of the kitchen waste pushed up by the stirring device 38 is also low, the vertical dimension of the drying tank 4 itself can be reduced by this. Further, since the upper surface opening is closed by the cover 44, it is also possible to prevent or suppress the internal kitchen waste (particularly powdered) from being scattered to the outside.

When the crossflow fan 23 rotates, the air heated by the drying chamber heater 24 is sucked by the crossflow fan 23 and discharged from the discharge port 51. The heated air discharged from the discharge port 51 passes through the window hole 36A of the locking member 36 on the left side of the drying tank 4, and then passes over the drying tank 4, and the window hole of the locking member 36 on the right side. After passing through 36A, it descends along the wall surface of the drying chamber 19 to the right, front, and rear of the drying tank 4. Then, it goes under the drying tank 4, and when it reaches the left side, it passes through the heating chamber filter 53 and enters the heating chamber 22 through the suction port 52. Then, each deodorizing device 2 in the heating chamber 22
After passing around 6 and 26, return to the drying chamber heater 24,
The circulation that is heated and sucked by the cross flow fan 23 again is repeated.

As a result, the kitchen waste in the drying tank 4 is heated from the surroundings through the entire wall surface of the drying tank 4.
Further, the left side surface 44B of the cover 44 is provided on the left side locking member 36.
Since it stands up at an angle corresponding to the window hole 36A of the left side surface 44A, a part of the circulating air passing through the window hole 36A is left side surface 44A.
It collides with B and further moves along the upper surface 44A. Therefore, the ventilation holes 46 on the left side surface 44B and the upper surface 44A are
.. From here, a part of the circulating air is positively introduced into the drying tank 4, whereby the kitchen waste in the drying tank 4 is uniformly and smoothly dried by heating from the surroundings and heating by the introduced air. Will be done.

At this time, since the deodorizing heaters 59, 59 are generating heat in the deodorizing devices 26, 26, the containers 64, 64 are
The temperature has risen above + 350 ° C. Moreover, since the deodorizing devices 26, 26 are on the circulation path of the air circulating in the drying chamber 19 as described above, the circulating air is heated by the residual heat dissipated by the deodorizing devices 26, 26 to the outside. Thermal efficiency is improved. Also, the left side surface 44B
Since the total opening area per unit area of each of the ventilation holes 46 ... Is larger than that of the other surface, the introduction of the circulating air into the drying tank 4 can be smoothly performed.

The microcomputer 98 is the temperature sensor 4
On the basis of the temperature in the drying chamber 19 detected by 9, for example, when the temperature in the drying chamber 19 reaches the upper limit temperature of + 120 ° C., the power supply to the drying chamber heater 24 is cut off (OFF), which is the above-mentioned lower limit temperature. ON-OFF control is performed to start (ON) energization when the temperature drops to + 110 ° C. Here, as described above, the circulating air is heated by the deodorizing devices 26, 26, but the capacity of the deodorizing heaters 59, 59 is the lower limit temperature in the drying chamber 19 as described above +11.
Since the circulating air in the drying chamber 19 cannot be heated to 0 ° C., the deodorizing heaters 59, 59 can be continuously energized while the ON / OFF control of the drying chamber heater 24 by the microcomputer 98 is performed without any trouble. Becomes
The deodorizing action of the deodorizing devices 26, 26 described below can be maintained without any trouble.

As the sirocco fan 77 rotates, the outside air is sucked through the intake pipes 74, ... As described above, and is discharged and introduced into the drying chamber 19 through the outside air inlet 78. As a result, fresh outside air necessary for drying is always introduced into the drying chamber 19. Further, as the sirocco fan 76 rotates, the air in the exhaust duct 67 is sucked and discharged as described above. On the other hand, as described above, due to the pressure difference between the inside and outside of the drying chamber 19, part of the circulating air passes through the deodorizing filter 56 and enters the container 64 through the front end openings of the deodorizing devices 26, 26.

Here, the deodorizing heater 59 constantly generates heat as described above, and the heat is transmitted to the fins 58 .... The air that has entered the container 64 passes through the ventilation holes 58A of the fins 58 around the deodorizing heater 59.
In the process of passing through here, the temperature is raised to around + 350 ° C as described above. Then, the high-temperature air passing through each fin 58 reaches the agitating material 63, but is partially dammed because it passes through the punching holes 62 of the agitating material 63.
As a result, a turbulent flow is generated and agitated.
The temperature of the air passed through is uniformed. After that, it flows into the catalyst 61 and is deodorized as described above. At this time, since the air temperature is made uniform by the stirring material 63 as described above, the deodorizing action by the catalyst 61 is also made uniform as a whole.

Further, since the air circulation itself in the deodorizing devices 26, 26 is caused by the pressure difference inside and outside the drying chamber 19 as described above, the amount of air passing through the container 64 is made uniform. In addition, the time required for air to pass through the catalyst 61 also depends on the catalyst 6
1 is a length sufficient to deodorize odorous components in the air. As a result, effective and efficient deodorization is performed in the deodorizing devices 26, 26.

The air deodorized in this way is transferred to the catalyst 61.
From the rear end opening into the exhaust duct 67, passing through the inside to reach the exhaust port 68. In this case, the duct member 66
Is in contact with the circulating air in the drying chamber 19, the heat of the high-temperature air flowing inside through the duct member 66 can also be used for heating the air circulating in the drying chamber 19. This further improves the thermal efficiency.

The air reaching the exhaust port 68 enters the heat exchange chamber 72 and exchanges heat with the outside air passing through the intake pipes 74, ... As described above. Therefore, the drying room 1
Since the outside air introduced into the inside 9 is heated by the high-temperature air discharged from the exhaust port 68, the thermal efficiency is further improved. The air that has passed through the intake pipes 74 ... Is mixed with a relatively large amount of outside air that flows in through the through holes 75 ... As described above, and is then discharged to the outside from the discharge port 76B by the sirocco fan 76. As a result, the exhaust gas temperature is significantly lowered, and the inconvenience caused by the high temperature exhaust gas is eliminated.

After performing such a drying operation for a predetermined time, the microcomputer 98 stops the operation of each device. At this time, the cooling of the inside of the drying chamber 19 may be performed by stopping the heat generation of the drying chamber heater 24 and operating the crossflow fan 23 for a predetermined period before stopping all the operations. Further, a buzzer or the like (not shown) may be activated by the end of the drying operation. After that, the heat insulation door 3
Open and take out the drying tank 4 forward. And the drying tank 4
After that, the garbage will be collected after drying.

As described above, in the present invention, the deodorizing devices 26, 2 are
Since 6 is arranged on the path of the air circulating in the drying chamber 19, the air circulating in the drying chamber 19 can be directly heated by the residual heat generated from the deodorizing devices 26, 26. Thereby, while deodorizing the exhaust air in the deodorizing device 26, the residual heat generated from the deodorizing device 26 is used to effectively heat the circulating air in the drying chamber 19 to significantly improve the efficiency of the garbage processing. You will be able to.

Further, the deodorizing heater 5 of the deodorizing devices 26, 26.
Since 9 and 59 have a heating ability that does not raise the temperature in the drying chamber 19 to the lower limit temperature for control by themselves, the deodorizing heater 59 is always heated while the drying chamber heater 24 is reliably heated. ON-OFF control can be performed. As a result, the deodorizing device 26
It becomes possible to execute the temperature control in the drying chamber 19 without any trouble while using the residual heat, and it is possible to realize an accurate heating and drying process of garbage.

38 and 39 show deodorizing devices 26, 2
6 is a front view excluding the heat insulating door 3 in an example in which 6 is arranged at both lower corners of the drying chamber 19. In this case as well, the front end openings of the deodorizing devices 26, 26 communicate with the inside of the drying chamber 19 via the deodorizing filter 56 and another deodorizing filter 56A, and their rear ends communicate with the exhaust duct 67. . According to such a configuration, the shape of the drying tank 4 enables the deodorizing devices 26, 26 to be arranged by effectively utilizing the dead spaces formed at the lower corners on both sides of the drying chamber 19, resulting in more space efficiency. Further improve.

According to the second aspect of the present invention, in addition to the above, a controller for controlling the energization of the drying chamber heater is provided, and this controller controls the drying chamber heater at a predetermined lower limit temperature and upper limit temperature of the drying chamber.
