6 is installed. In addition, the lid 14 can be opened and closed with respect to the garbage processing machine main body 18 by a hinge 17, and the lid 14
A lid packing 19 is provided so that the steam generated from the garbage does not leak. The upper ends of the heat insulating container 1 and the garbage storage container 2 and the lower surface of the lid 14 are arranged with a gap therebetween, and serve as a passage for water vapor generated from the garbage.

The odor detecting means 25 detects rotten odors such as burnt odor (aldehyde), fishy odor (amine), orange odor (limonene) and sour odor (acid) which are filled in the garbage storage container 2 during the pulverizing and drying process. It is to be detected and is installed in the garbage storage container 2. The output of the odor detecting means 25 changes according to the amount of odor, and is connected to the input means 22. The control means 21 inputs the outputs of the inside temperature detector 6, the water vapor temperature detector 7, and the odor detecting means 7 via the input means 22, and controls the output of the heater 16 on / off via the output means 23. The phase is controlled, the drying process is performed while controlling the stirring fan 15 and the cooling fan 9, and the odor is controlled as much as possible.

The operation of the first embodiment of the present invention will be described below with reference to FIG.
Will be described. Kitchen 24 put in kitchen storage container 2
By turning on the power switch of the garbage processor,
The rotary blade 4 rotates. The kitchen waste 24 is stirred, and the rotary blade 4 and the fixed blade 3 start crushing. At the same time, the stirring fan 15 and the heater 16 operate to start heating. The hot air generated by the stirring fan 15 and the heater 16 heats the kitchen waste 24 while circulating in the space formed by the lower surface of the lid 14 and the kitchen waste container 2. As shown in FIG. 2, the inside temperature detector 6
When the in-compartment temperature detected by is 130 ° C, temperature adjustment of the in-compartment temperature is started. As a result, the temperature of the kitchen waste 24 itself rises, and the moisture and odor contained in the kitchen waste 24 are mixed with the water vapor and released.

As the heating time elapses, the odor increases and the output voltage of the odor sensor (odor detecting means) increases. At the same time, the pressure inside the garbage storage container 2 also rises due to the vapor pressure, and the odor easily leaks from the gaps of the garbage processing machine. The control means 21 controls the inside temperature to be a predetermined temperature, for example, 1
The output of the heater 16 is continuously controlled by the output of the internal temperature detector 6 so that the temperature becomes 30 ° C. When the output of the odor detecting means 25 exceeds a predetermined upper limit value, the heating of the heater 16 is stopped or the power is down, and the temperature in the refrigerator is waited for. Then, when the output of the odor detecting means 25 becomes equal to or lower than the predetermined lower limit value, the heating of the heater 16 is started again, and the inside temperature is kept at 130.
Adjust the temperature to ℃. In this way, the drying process is continued while preventing the odor of the kitchen waste 24 from being generated so that the odor becomes a predetermined amount or less.

In this way, when the odor detecting means 25 detects a odor of a predetermined amount or more, the heating of the heater 16 is stopped according to the output, and the odor and the pressure inside the chamber are suppressed due to the heating. As a result, it is possible to reduce the leakage of odors from the gaps in the garbage processing machine, the bearings of the stirring fan, the joints of the screw parts and parts, the packing, and the like.

When the kitchen waste 24 is heated in the kitchen storage container 2, the surface temperature is higher near the heater 16 and the temperature inside the lump of kitchen waste 24 is lower. As described above, heating and stopping of the heater 16 are repeated according to the detected amount of odor. Then, the temperature of the kitchen waste 24 becomes uniform while the heating of the heater is stopped, the charring is eliminated, and the odor is further reduced.

Even if a predetermined amount of odor is generated, the heater is not stopped, and even if the electric power applied to the heater is reduced by the phase control, the same effect as when the heater is stopped can be obtained. By doing so, it is possible to efficiently perform the drying process in a short time while suppressing the odor to a predetermined amount or less.

As the odor detecting means, there are sensors having various characteristics, and it is necessary to select the sensor according to the odor to be detected. Also, as odor detection means, changes in pressure,
When the amount of water vapor or the like can be substituted, a pressure, humidity sensor or the like may be used.

There are some odors generated during the garbage treatment as described above, and in order to deal with a plurality of odors, a plurality of odor sensors may be connected to the control means to control the heating means. .

Next, since the basic construction of the second embodiment of the present invention is the same as that of FIG. 1, the operation will be mainly described below with reference to FIG.

The kitchen waste 24 put in the kitchen storage container 2 is
When the power switch of the garbage processing machine is turned on, the rotary blade 4 starts to rotate. The kitchen waste 24 is stirred, and the rotary blade 4 and the fixed blade 3 start crushing. The hot air from the stirring fan 15 and the heater 16 heats the kitchen waste 24 while circulating in the space formed by the lower surface of the lid 14 and the kitchen waste container 2.
When the temperature of the kitchen waste 24 rises, the water content and odor contained in the kitchen waste are mixed with the water vapor and released from the kitchen waste.

As shown in FIG. 3, the odor begins to increase as the heating time elapses. At the same time, the pressure inside the garbage storage container 2 also rises, creating a situation in which the odor easily leaks from the gaps in the garbage processing machine. The control means 21 continues to control the output of the heater 16 by the inside temperature detector 6 so that the inside temperature becomes 130 ° C. Then, as shown in FIG. 3, when the output voltage of the odor sensor (odor detecting means) exceeds a predetermined upper limit value, the rotation of the rotary blade 4 is stopped and the output of the odor detecting means is reduced. wait. Then, when the output of the odor detecting means falls below a predetermined lower limit value, the rotary blade 4
The rotation of No. 24 is started again, and the garbage 24 is crushed. In this way, the pulverizing and drying process is continued.

The control means 21 stops the rotating blade 4 or reduces the number of rotations when the output of the odor detecting means exceeds a predetermined amount. When the output falls below a predetermined amount, the rotary blade 4 is rotated. When the rotary blade 4 rotates, the garbage 24 is crushed and the vapor and odor accumulated inside are dispersed. At the same time, an odor is generated. When the odor detection unit 7 detects a predetermined amount of odor or more, the control unit 24 stops the rotation of the rotary blade 4. It suppresses the generation of odor and pressure due to the crushing of the rotary blade 4, and reduces the leakage of odor from the gap in the garbage processing machine, the bearing of the stirring fan, the screw part, the joint part of parts, the packing and the like.

When the kitchen waste 24 is in the kitchen storage container 2, the temperature is higher as it is closer to the heater 16, and the temperature inside the kitchen waste 24 is lower. When the rotary blade 4 is turned, the heat and steam accumulated inside the kitchen waste 24 are expelled all at once. The rotation of the rotary blade 4 is controlled according to the odor generation amount so that the steam or heat is emitted when the odor generation amount is small.

Even if the rotary blade 4 is not stopped, but the rotation speed of the rotary blade 4 is lowered, the same effect as when the rotary blade 4 is stopped can be obtained.

When the control of the rotary blade 4 is combined with the first embodiment, that is, the heater and the rotary blade are controlled by the output of the odor detecting means, the odor can be further reduced.

In this embodiment, the rotary blade is described as being continuously rotated when the odor is not small, or continuously rotated in the forward and reverse directions. However, the rotary blade may be intermittently operated in a few minutes to a few seconds. On / off control may be performed according to the amount of odor while performing the above.

Next, a third embodiment of the present invention will be described with reference to FIG. The same parts as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted. In addition to the first embodiment, in order to reduce the odor of the garbage 24, an ozone generator connected to the garbage storage container 2 and sending the generated ozone into the garbage storage container 2, and sending fresh air. A deodorizing device 26 such as an air pump for reducing the odor of the garbage 24 is added.

The operation of the third embodiment of the present invention will be described below with reference to FIG. Kitchen 24 put in kitchen storage container 2
Is crushed by the rotary blade 4 and the fixed blade 3. The hot air from the stirring fan 15 and the heater 16 heats the kitchen waste 24 while circulating in the space formed by the lower surface of the lid 14 and the kitchen waste container 2. The control means 21 continues the drying process while controlling the output of the heater 16 by the in-compartment temperature detector 6 so that the temperature inside the garbage storage container 2 becomes a predetermined temperature. Similarly, when the output of the odor detection means 25 exceeds a predetermined amount,
Ozone or air is introduced from the deodorizing device 26 into the garbage storage container 2, and when the output of the odor detecting means 25 decreases, the introduction is stopped. Although the deodorizing device 26 has been described by using the ozone generating device, the air pump, or the like, any device that reduces odor may be used.

The deodorizing device 26 using a pump or the like has a life time. Therefore, control is performed so that the maximum deodorizing effect is exerted in the shortest drive time.

When ozone is continuously supplied, the amount of ozone in the garbage storage container 2 increases. As a result, it becomes difficult to satisfy the safety standard for residual ozone amount. Therefore,
Ozone driving is performed in the shortest possible driving time.

Next, since the basic construction of the fourth embodiment of the present invention is the same as that of FIG. 1, the operation will be mainly described below with reference to FIG.

The operation of the above configuration will be described. The kitchen waste 24 thrown into the kitchen storage container 2 includes a rotary blade 4 and a fixed blade 3.
Is crushed by. The hot air from the stirring fan 15 and the heater 16 heats the kitchen waste 24 while circulating in the space formed by the lower surface of the lid 14 and the kitchen waste container 2. Control means 21
Keeps heating until the output voltage of the odor sensor (odor detection means 25) reaches a predetermined amount, and stops heating when the output voltage reaches a predetermined amount. Then, when the amount becomes equal to or less than a predetermined amount, heating is started. By performing this repetitive control, it is possible to reduce the amount of odor generated to a predetermined amount or less and to carry out garbage treatment in a short time.
The odor such as rotten odor is regarded as an unpleasant odor, and the smaller the amount generated, the better. However, the odor generated during the crushing and drying process of kitchen waste is difficult to prevent. In particular, the odor generating process is likely to occur near the end of the drying process. This means that it has a burning odor.

This means that when the kitchen waste is crushed and dried at a temperature as low as possible, the burning odor is less.
However, crushing and drying at a low temperature in turn increases the processing time for kitchen waste. In addition, the amount of odor generated during the crushing and drying process varies depending on the contents of the kitchen waste. By controlling each load according to the amount of odor generated, optimum control with the minimum odor can be achieved. The mechanism of odor generation differs depending on the type of kitchen waste and the amount of kitchen waste. That is, the heating temperature of the kitchen waste which starts to generate odors is different. Therefore, by controlling the heating temperature according to the amount of odor generated, the garbage processing time can be shortened.

When a combination of the above-mentioned embodiments is carried out, a further deodorizing effect can be expected.

[0049]

As described above, according to the invention of claim 1, at least one or more odor detecting means is arranged in the garbage storage container, and the heating means is controlled according to the output of the odor detecting means. The amount of bad odor generated can be suppressed, and thus the bad odor leaking from the garbage processing machine can be reduced.

According to the second aspect of the present invention, since the rotation of the rotary blade is controlled according to the output of the odor detecting means, the amount of the bad smell can be suppressed not only by the heating control but also by the rotary blade control. It is possible to reduce the generation of bad odor.

According to the third aspect of the present invention, the deodorizing means for deodorizing the kitchen waste is provided, and the drive of the deodorizing device is controlled according to the output of the odor detecting means. Therefore, the deodorizing effect of the deodorizing device can be obtained, and the odor can be further reduced. Can be planned. Further, although the life of the deodorizing device is not long, it is possible to extend the life of the deodorizing device by operating the deodorizing device only when the odor detecting means needs to operate.

According to the invention of claim 4, the drying process is carried out while changing the heating temperature in the garbage processing container in accordance with the output of the odor detecting means, so that the time for the drying process is shortened while suppressing the generation of a bad odor. be able to.
