2. Description of the Related Art In the garbage disposal, depending on the heating source, there are a method using combustion heat, a method using microwaves, a method using an electric heater, and the like. Since the garbage treatment device that uses combustion heat uses gas fuel, liquid fuel, etc., the entire device becomes complicated and large, and there is a problem in safety. In addition, the kitchen waste processing apparatus using microwaves is suitable for drying the kitchen waste with a high water content because the microwaves are selectively absorbed by the water in the kitchen waste, but it is somewhat safe and controllable. There are difficulties. On the other hand, the garbage processing device using the electric heater has excellent safety and controllability, and it is easy to reduce the size and cost of the device.

Focusing on this point, the present inventors have made various studies on the garbage treating apparatus using an electric heater, and as a result, have proposed the garbage treating apparatus as shown in FIG. The configuration will be described below. As shown in FIG. 15, the heat insulating container 1
Has a kitchen storage container 2 installed therein so that it can be taken out freely. A fixed blade 3 is provided on the inner wall of the garbage storage container 2.
The rotary blade 4 in the kitchen storage container 2 is connected to a motor 5 and rotated. The inside temperature detector 6 is arranged so as to detect the ambient temperature inside the kitchen storage container 2. The water vapor temperature detector 7 detects the temperature of water vapor flowing from the garbage storage container 2 to the condensing means 8, and is installed on the outer wall surface of the condensing means 8.

A condenser 8 and a cooling fan 9 for air-cooling the outer surface of the condenser 8 are installed on the outer periphery of the heat insulating container 1. A condensed water outflow portion 10 is provided below the condensing means 8, and a gas release pipe 11 for releasing steam (gas including odor) generated from the garbage from a part of the condensed water outflow portion 10.
And a deodorizing device 12 is provided on the gas discharge pipe 11. A condensed water container 13 is provided below the condensed water outlet 10.

Further, the lid 14 can be opened and closed with respect to the garbage processing device main body 18 by a hinge 17, and the lid 14 is provided with a lid packing 19 to prevent water vapor generated from the garbage from leaking. 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 control means 21 inputs the output of the inside temperature detector 6 and the output of the water vapor temperature detector 7 through the input means 22, controls the output of the heater 16 through the output means 23, and agitates the stirring fan. The drying process is performed while controlling the cooling fan 15 and the cooling fan 9, and the drying process is terminated when the temperature change amount of the water vapor temperature detector 7 changes from the maximum value by a predetermined amount or more.

Steam is generated from the heated garbage 24 and overflows into the condensing means 8. Due to the function of the heat insulation container 1, the temperature of the condensing means 8 is lower than that of the inside of the garbage storage container 2, so that the water vapor is condensed and collected in the condensed water container 13. When the garbage 24 approaches the end of drying, the amount of steam generated decreases, so that the temperature of the steam temperature detector 7 provided on the side surface of the outer wall of the condenser 8 changes (decreases). Therefore, the drying process is terminated when the temperature change amount of the water vapor temperature detector 7 becomes equal to or more than a predetermined amount.

[0009]

However, the drying process is continued while the condensed water container 13 is full, or
If the condensed water container 13 is left detached, the condensed water will flow toward the gas discharge pipe during the drying process, and finally the deodorizing device 12 will also have cold condensed water.

The internal temperature detector 6 is arranged so as to detect the ambient temperature inside the kitchen storage container 2. The water vapor temperature detector 7 detects the temperature of water vapor flowing from the garbage storage container 2 to the condensing means 8, and is installed on the outer wall surface of the condensing means 8.

On the outer peripheral portion of the heat insulating container 1, a condensing means 8 is provided.
A cooling fan 9 for air-cooling the outer surface of the condensing means 8 is installed. A condensed water outflow portion 10 is provided in the lower part of the condensing means 8, and a gas discharge pipe 1 for releasing a gas containing water vapor and odor generated from the garbage 24 to a part of the condensed water outflow portion 10.
1 is connected. A deodorizing device 12 is attached to the gas discharge pipe 11.
The deodorizing device 12 deodorizes the gas, and the deodorized gas is discharged from the exhaust port 32.

Below the condensed water outflow portion 10, the condensing means 8 is provided.
A condensed water container 13 for accumulating the condensed water that has passed therethrough and a stop valve 20 for preventing the condensed water from spilling when the condensed water container 13 is removed are provided. A lid 14 is provided above the condensing means 8, and an agitating fan 15 and a heater 16 are installed on the inner surface of the lid 14 as heating means. Further, the lid 14 can be opened and closed with respect to the kitchen waste processing machine main body 18 by a hinge 17, and the lid 14 is provided with a lid packing 19 so as to prevent water vapor generated from the kitchen waste 24 from leaking.

The deodorizing device 12 includes a catalyst 25 for removing a rotten odor, a burning odor, etc. sent through the gas discharge pipe 11,
A catalyst heater 26 for heating the temperature of the catalyst 25 to a predetermined temperature in order to activate the function of the catalyst 25;
The temperature sensor 27 is composed of a thermocouple, a thermistor or the like for obtaining temperature information for controlling the heating of 6 to a predetermined temperature.

The control means 21 outputs the outputs of the inside temperature detector 6, the steam temperature detector 7 and the temperature sensor 27 of the catalyst 25,
On / off control and phase control are performed on the output of the heater 16 and the catalyst heater 26 via the input means 22 and the output means 23, and the drying process is performed while controlling the stirring fan 15 and the cooling fan 9. To do.

The operation of the first embodiment of the present invention will be described below. The kitchen waste 24 put in the kitchen storage container 2 is rotated by the power of the kitchen processing machine, the rotary blade 4 rotates, the kitchen waste 24 is agitated, and the rotary blade 4 and the fixed blade 3 start crushing the kitchen waste 24. It 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 circulates in the space formed by the lower surface of the lid 14 and the garbage storage container 2 to heat the garbage 24. Control means 21
Controls the output of the heater 16 by the output of the internal temperature detector 6 so that the internal temperature becomes 130 ° C., for example.

The kitchen waste 24 is dried with hot air, and steam is generated from the kitchen waste 24. The water vapor flows out from the garbage storage container 2 to the condensing means 8. The steam that has flown out to the condensing means 8 whose outer surface is air-cooled by the cooling fan 9 is condensed into water and flows into the condensed water container 13 through the condensed water outflow portion 10. In this way, the drying process is continued. The detection of the end of the drying process of the garbage 24 is performed by detecting the temperature change of the water vapor temperature detector 7.

When this drying process starts, steam starts to be generated, and the temperature of the steam temperature detector 7 rises according to the amount of steam generated. When the garbage 24 is almost dried, the amount of water in the garbage 24 decreases, the generation of water vapor decreases, and the temperature of the water vapor temperature detector 7 also decreases. The control means 21 monitors the progress of the water vapor temperature detector 7, and the temperature of the water vapor temperature detector 7 is a set value from the peak value (for example, 15 ° C.).
In the following cases, the control means 21 detects the end so that the drying is completed.

The above operation is an operation when the operation of the garbage processing machine is normal. If the user continues the pulverizing and drying process while the condensed water container 13 is filled with water, the water in the condensed water container 13 will overflow. Alternatively, in the unlikely event that the user continues the pulverization / drying process with the condensed water container 13 removed, the water shutoff valve 20 operates and the condensed water becomes the condensed water container 13
It does not flow to the deodorizing device 12 through the gas discharge pipe 11. Normally, the temperature of the catalyst heater 26 during the drying process is adjusted to about 600 ° C. as shown in FIG.
The deodorizing function of the catalyst 25 is activated. In this state, when water enters the deodorizing device 12 through the gas discharge pipe 11, the water is heated by the catalyst heater 26 and becomes steam. Due to the temperature of the steam, the temperature of the temperature sensor 27 provided in the catalyst heater 26 of the deodorizing device 12 decreases.

The temperature of the temperature sensor 27 is monitored, and if the temperature of the temperature sensor 27 drops below a certain set value or a certain ratio during the drying process, the heating of the catalyst heater is stopped,
The control means 21 controls the catalyst heater 2 so that the drying process is also stopped.
Control 6 In this way, it is possible to prevent the catalyst heater 26 from being easily cut off due to thermal shock or the like, and to prevent its life from being shortened.

As described above, when water is applied to the high temperature catalyst heater 26, thermal shock is applied to the catalyst heater 26. If this thermal shock is repeatedly performed, it becomes easy for the catalyst heater to break. In order to prevent this disconnection and reduce the thermal shock applied to the catalyst heater 26 as much as possible, the temperature sensor 2 in the deodorizing device
When there is a rapid change in the temperature of 7, the heating of the catalyst heater 26 is stopped. As a result, odor is likely to be generated from the deodorizing device 12, so the pulverizing and drying process may be stopped at the same time as the catalyst heater 26 is stopped.

Next, a second embodiment of the present invention will be described with reference to FIGS. The same components as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted. In this embodiment, in addition to the first embodiment, in order to quickly detect the water passing through the gas discharge pipe 11 in the deodorizing device 12, the temperature sensor 27 in the deodorizing device 12 is deodorized in FIG. Device 12
In the vicinity of the suction port 31 of FIG. Each temperature sensor 27 of FIG. 3 and FIG.
Is constituted by a control circuit 21 for controlling the heating of the catalyst heater 26 to be stopped when the temperature changes to a predetermined temperature or a predetermined rate or more.

The operation of the above configuration will be described with reference to FIG. Up to the point where the inside of the deodorizing device 12 is flooded, it is the same as in the first embodiment. As shown in FIG. 5, when the water flows in through the gas discharge pipe 11, the temperature sensor 27 disposed at the suction port 31 of the deodorizing device 12 in FIG. The temperature of 27 drops. When water flows in through the gas discharge pipe 11, the temperature sensor 27 arranged on the bottom surface of the deodorizing device 12 in FIG. 4 collects the inflowing water on the bottom surface of the deodorizing device 12, and the temperature of the temperature sensor 27 immediately increases. descend. This temperature sensor 2
The temperature of No. 7 is monitored, and the control means 21 controls to stop the drying process when the temperature of the temperature sensor 27 changes to a certain value or a certain ratio during the drying process. In this manner, the control means 21 immediately stops the heating of the catalyst heater 26 and judges that the water has entered the deodorizing device 12 more quickly than in the first embodiment, and the catalyst heater 26 is stopped. It is possible to prevent the catalyst heater from being burned out, which is likely to occur due to thermal shock, and to prevent its life from being shortened.

The position of the temperature sensor differs depending on the size and configuration of the deodorizing device, and may be any position as long as it can be detected quickly. Also, both may be attached depending on the configuration.

Next, a third embodiment of the present invention will be described with reference to FIGS. 6 and 7.
Use to explain. The same components as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted. In this embodiment, in addition to the first embodiment, in addition to the temperature sensor 27 for detecting the temperature of the catalyst heater 26, a second temperature detecting means 28 is provided.
In the gas discharge pipe 11 or the suction port 31 of the deodorizing device 12
The temperature output of the second temperature detecting means 28 is connected to the control means 21 through the input means 22 in the vicinity or in the catalyst heater 26 and near the suction port 31 of the deodorizing device 12.

The operation of the above configuration will be described with reference to FIG. Up to the point where the deodorizing device 12 is flooded, it is the same as in the first embodiment. The second temperature detecting means 28 is under the influence of the deodorizing device 12 which is at a high temperature and has a temperature higher than room temperature (about 100 ° C.). In this state, when the water cooled by the cooling fan 9 passes through the gas discharge pipe 11 and reaches the second temperature detecting means 28, the temperature of the second temperature detecting means 28 decreases. The control means 21 monitors the temperature of the second temperature detection means 28 of the gas discharge pipe 11. During the drying process, when the temperature of the second temperature detecting unit 28 changes to a certain value or a certain ratio or more, the control unit 21 controls to stop the drying process. In this way, by detecting the temperature decrease of the second temperature detecting means 28, it is judged that the deodorizing device 12 is submerged, the control means 21 stops the heating of the catalyst heater 26, and reheats the catalyst heater 26. It is possible to prevent the shortening of the life due to.

In this embodiment, the inflow of water is detected before the water enters the deodorizing device, the control means 21 immediately stops the heating of the catalyst heater 26, and the catalyst heater 26 is turned off by reheating the catalyst heater 26. It is possible to prevent the deterioration of life.

Next, a fourth embodiment of the present invention will be described with reference to FIG. The same components as those of the first embodiment are designated by the same reference numerals and the description thereof will be omitted. In the present embodiment, in addition to the first embodiment, the suction port 31 of the deodorizing device 12 connected to the gas discharge pipe 11 is arranged at a position higher than the exhaust port 32 of the deodorizing device 12.

The operation of the above structure will be described. Up to the point where the deodorizing device 12 is flooded, it is the same as in the first embodiment. During the pulverization and drying, the vapor pressure in the garbage storage container 2 rises, and the water accumulated in the gas discharge pipe 11 is pushed into the deodorizing device 12. However, as shown in FIG.
Is placed on top of the deodorizing device 12, and the discharge port
By arranging the water in the lower part of the deodorizing device 12, it is difficult for the water accumulated in the gas releasing pipe 11 to enter the deodorizing device 12, and the water once entering the deodorizing device 12 is easily discharged from the outlet. There is. In the unlikely event that the water that entered the deodorizing device 12,
The catalyst 25 and the catalyst heater 26 are applied to cool the catalyst heater 26. However, the water once entering the deodorizing device 12 is immediately discharged to the outside from the exhaust port 32 of the deodorizing device 12. Due to the water immersion, a thermal shock is instantaneously applied to the catalyst heater 12, but since the water is immediately discharged through the exhaust port 32, the thermal shock until the contained water evaporates can be shortened. The life of the heater 26 will be extended.

In FIG. 8, water is collected in the lower part of the deodorizing device 12. However, in order to prevent water from collecting in the deodorizing device 12, a small hole is opened in the bottom surface of the deodorizing device and used as a discharge port. good. By doing so, the deodorizing device 12
It is difficult for water to enter the inside, and once entered, it is easy to drain it. The water discharged from the deodorizing device 12 may be naturally dried by receiving it in a tray or the like.

Next, a fifth embodiment of the present invention will be described with reference to FIG. The same components as those of the first embodiment are designated by the same reference numerals and the description thereof will be omitted. In the present embodiment, in addition to the first embodiment, a catalyst heater 26 having a convex top surface is used, and even if water is applied to the catalyst heater 26, water does not accumulate on the top surface of the catalyst heater 26. The catalyst heater has such a structure.

The operation of the above configuration will be described. The process up to the point where condensed water enters the deodorizing device 12 through the gas discharge pipe 11 is the same as in the first embodiment. During the pulverization and drying, the vapor pressure in the garbage storage container 2 rises, and the water accumulated in the gas discharge pipe 11 is pushed into the deodorizing device 12. As a result, the water that has entered the deodorizing device 12 is applied to the catalyst 25 and the catalyst heater 26 and cools the catalyst heater 26. The water on the high-temperature catalyst heater 26 vigorously jumps in the deodorizing device 12. The splashed water also reaches the top surface of the catalyst heater 26. However, even if the top surface of the catalyst heater 26 is splashed with water, the top surface of the catalyst heater 26 is convex, so that the water immediately falls from the catalyst heater 26.
In this way, thermal shock due to water and heating is applied to the catalyst heater, but compared to when the shape of the top surface of the catalyst heater is concave,
The time when the thermal shock is applied is shortened, and the life of the catalyst heater 26 is extended.

In the embodiment shown in FIG. 9, the deodorizing device 12 has the intake port 31 at the upper part and the exhaust port 32 at the lower part. However, when water enters the deodorizing device 12, the deodorizing device 12 will be described.
Since the water inside the water splashes, it can be applied regardless of whether the intake port or the exhaust port 32 is located.

Next, a sixth embodiment of the present invention will be described with reference to FIGS. The same components 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, a vapor detecting means 29 is arranged in the deodorizing device 12, and its output is connected to the control means 21 through the input means 22. When the steam detecting means 29 detects steam, the control circuit 21 controls to stop heating of the catalyst heater 26.

The operation of the above structure will be described with reference to FIG. The process up to the point where condensed water enters the deodorizing device 12 through the gas discharge pipe 11 is the same as in the first embodiment. As shown in FIG. 11, when the inside of the deodorizing device 12 is not invaded with water, the steam cannot be detected, so the output of the steam detecting means 29 is low. At that time, if water should enter the deodorizing device 12 due to some abnormality, the catalyst heater 26, which has a high temperature, converts the water into steam and evaporates it. As shown in FIG. 11, this steam is detected by the steam detecting means 29, and the drying process is stopped.
The control means 21 controls.

In this way, when the vapor detecting means 29 detects vapor, it is judged that the deodorizing means 12 is invaded, and the control means 21 stops heating the catalyst heater 26 and reheats the catalyst heater 26. This prevents the life of the catalyst heater 26 from being shortened.

Next, a seventh embodiment of the present invention will be described with reference to FIGS. 1, 12 and 13 used in the first embodiment.

First, the operation will be described with reference to FIGS. When the power of the garbage processing device is turned on, heating of the catalyst heater 26 in the deodorizing device 12 is started. When there is no water in the deodorizer 12, the temperature of the temperature sensor 27 in the catalyst heater 26 rises while drawing a clean parabolic curve as shown in FIG. 12, and reaches 600 ° C. which is the heating temperature of the catalyst heater. . On the other hand, when water is contained in the deodorizing device 12, the temperature of the temperature sensor 27 of the catalyst heater 26 evaporates the water at about 100 ° C. in order to evaporate the water once as shown in FIG. Keep up to. Then, when this water is completely evaporated, the temperature of the temperature sensor 27 rises while drawing a parabolic curve. As described above, when the temperature of the temperature sensor 27 of the catalyst heater 26 is equal to or lower than a predetermined temperature (for example, 300 ° C.) and the rate of temperature rise (temperature rise for a certain time / some time) is less than or equal to a set value, control is performed. Means 2
No. 1 determines that "the inside of the deodorizing device 27 is flooded", and the control means controls the heating of the catalyst heater 26 to be stopped, thereby preventing the decrease in life caused by the heating of the catalyst heater 26 at the time of startup. You can do it.

The above predetermined temperature (for example, 300 ° C.) is set to be slightly higher than the temperature (about 100 ° C.) at which the temperature rise rate of the temperature sensor 27 becomes equal to or less than the set value when water enters the deodorizing device 12. I am doing it.

Next, an eighth embodiment of the present invention will be described with reference to FIGS. 6 and 14 used in the third embodiment.

The process up to the point where the deodorizing device 12 is flooded is the same as in the third embodiment. Second temperature detecting means 28
Is affected by the high temperature deodorizing device 12, and has a temperature higher than room temperature. In this state, the water cooled by the cooling fan 9 passes through the gas discharge pipe 11 and the second
When the temperature detecting means 28 is applied, the temperature of the second temperature detecting means 28 decreases. The control means 21 monitors the temperature of the second temperature detection means of the gas discharge pipe 11 and the temperature of the temperature sensor.
During the drying process, the second temperature detecting means 28 and the temperature sensor 27.
The control means 21 controls the drying process to be stopped when the temperature difference changes to a certain value or a certain ratio or more. In this way, the decrease in the temperature difference between the second temperature detector and the temperature sensor 27 is detected, it is determined that the deodorizing device 12 is flooded, and the control means 21 stops the heating of the catalyst heater 26 and the catalyst heater It is possible to prevent a decrease in life due to reheating of 26.

In this embodiment, the inflow of water is detected before the water enters the deodorizing device 12, the control means 21 immediately stops the heating of the catalyst heater 26, and the catalyst heater 26 is reheated. It is designed to prevent cutting and shortening of life. Further, in this method, since the reference temperature is the temperature sensor 27, it is less likely to be affected by the ambient temperature, and malfunctions are reduced.

It is further effective if the above embodiments are combined and implemented.
