Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food waste treatment apparatus for composting kitchen garbage such as kitchen waste generated in a home kitchen by aerobic fermentation and decomposition, and more particularly to a water removal mechanism when used in cold regions. Regarding

[0002]

2. Description of the Related Art Composting of garbage is accomplished by fermenting and decomposing organic matter in the garbage with the help of microorganisms. In this fermentation, a method of aerobic fermentation decomposition in which oxygen is given to the processed product to ferment is generally adopted, because the fermentation heat obtained during fermentation is large and the generation of a bad odor associated with fermentation is small. ing. In order to promote this aerobic fermentation, it is necessary to prepare an optimal environment for the activity of microorganisms. It is necessary to maintain the water state, supply oxygen necessary for fermentation, and keep the temperature at an appropriate level.

For this reason, in the conventional general food waste treating apparatus, in addition to the reaction tank, a stirring means for equalizing the state of the entire processed material put into the reaction tank and oxygen are supplied. It is provided with a ventilating means for adjusting the water state and a heating means for keeping the temperature inside the reaction tank at a certain value.

[0004]

In the above-mentioned general food waste treating apparatus, water, oxygen, temperature, etc. are considered to be indispensable factors in order to promote aerobic fermentation by the activity of microorganisms. However, excess water will hinder the supply of oxygen, so excess water can be effectively removed by adjusting the amount of air or raising the temperature in the reaction tank. There is.

However, the water evaporated from the processed material by the heating means provided to keep the temperature inside the reaction tank at a certain value is a fan, which is a means for feeding evaporated water as a ventilation means in an environment other than the cold region. However, in a cold region, the water may be condensed and liquefied after being evaporated, and the condensed water may be dropped into the processed material and return to the processed material again. For this reason,
The electric power energy spent for moisture evaporation may not effectively contribute to moisture removal, and so-called energy efficiency derived from the amount of moisture removed with respect to the heating energy spent for moisture evaporation may be very poor. Therefore, it is possible to increase the air volume of the exhaust suction fan installed in the reaction tank to discharge the evaporated water before dew condensation, but this method has almost no effect on water removal under a freezing environment. Depending on the situation, the water removal rate may not be improved.

On the other hand, as a method of preventing the dew condensation and discharging the evaporated water, it is considered that hot air is blown into the reaction tank. However, this method requires a fan for blowing hot air in addition to the heating means, and therefore the cost of the processing apparatus cannot be denied. Therefore, it is possible to avoid the cost increase by ventilating by using only the hot air blowing fan instead of the suction fan installed in the reaction tank. Can not be made negative pressure, and thereby, odor filling and dust scattering become remarkable. Moreover, since the heating means installed in the reaction tank cannot be made so large because the installation space in the reaction tank is limited, it is necessary to increase the temperature density, which results in an abnormally high temperature of the heating means. Will be unavoidable.

The object of the present invention is to solve the problems in the above-mentioned conventional garbage disposal, particularly in the garbage disposal used in cold regions, so as not to lower the moisture removal rate in cold regions and to improve energy efficiency. An object of the present invention is to provide a food waste processing device that can prevent the deterioration.

As shown in FIGS. 3 and 6, the heater 36 is disposed above the inner space of the reaction vessel 22 and the charging port lid 15 is provided.
It is placed so that it does not interfere with the processed object,
A heat insulating material 39 is attached to the side opposite to the processed object via a reflecting plate 38. Both ends of the heater 36 in the extension direction are supported by a heat insulating material 38, and a column 39A fixed to this heat insulating material 39 is shown in FIG.

Power supply from the power supply is started at.

Since the present embodiment is constructed as described above,
When processing a processed material such as garbage in a place other than a cold region, when the power switch 13 is turned on, the electric power from the power circuit 32 in the control board 31 is exhausted by the exhaust fan 29.

As a result, the standard configuration of the device can be adapted to the cold region.

When the outside air temperature detecting means 37 provided in the cold region specification unit 35 reaches a predetermined temperature or lower, the outside air temperature detecting means 37 is switched to the energized state to supply power to the heater 36 from the power source. And heater 3
6 is heated to generate heat inside the space of the reaction tank 22 and the heater 36.
It is possible to heat the surface of the processed material facing each other.
Moisture contained in the processed material is evaporated by the heater 30 located on the side of the reaction tank bottom plate 22B and stays above the reaction tank 22 to cause dew condensation due to the influence of the outside temperature. Since the inside of the space of the tank 22 is heated, the progress of dew condensation is suppressed. As a result, the water evaporated from the treated material is discharged from the reaction tank 22 toward the exhaust port 18 side, which has a tendency to have a negative pressure by the exhaust fan 29, without dew condensation.

The present inventor conducted experiments on the removal of evaporated water in an environment of −10 ° C. with respect to the standard configuration when the outside air temperature is −10 ° C. and the configuration equipped with a cold region specification unit. The results shown in FIGS. 8 and 9 were obtained. That is, in FIGS. 8 and 9, (A) is the result when the cold district specification unit 35 is attached, and (B) is the result of the configuration of the standard specification. FIG. 8 shows the amount of evaporated water removed, and FIG. 9 shows the processed material in the reaction tank 22 and the heater 3.

The configuration with 5 attached is expressed as "heater mounting specifications", and the configuration of standard specifications is expressed as "standard specifications". As is clear from FIG. 8, cold region specification unit 3
In the configuration with 5 attached, the amount of water removed was 710 g / day, whereas in the configuration with standard specifications, only 370 g / day was obtained, which was about a double difference. Further, as is clear from FIG. 9, regarding the temperature above the inside of the space of the reaction tank 22,
In the configuration with the cold district specification unit 35 attached, 1 ° C to
While 6 ° C, the standard configuration resulted in -6 ° C. In the configuration provided with the cold region specification unit 35, when the outside air temperature reaches or exceeds the predetermined temperature, the heater 36 is not energized by the outside air temperature detecting means 37. Temperature and ventilation controls are provided.

According to the present embodiment, the board-side connector 34 is simply provided for the electrical equipment box 28 having the control board 31 for controlling the temperature and the ventilation in the reaction tank 22 in the standard specification configuration. Since the configuration enables electrical connection with a cold region specification unit 35 to be attached later, it is not necessary to change the specifications of the electrical equipment box 28 itself. As a result, it is not necessary to distinguish the specifications of the electrical equipment box 28, so that it is possible to obtain a configuration of cold district specifications without increasing manufacturing costs.

Next, another embodiment of the present invention will be described with reference to FIG. In the embodiment shown in FIG. 10, when power is supplied to the heater 30 used for temperature management in the reaction tank 22 and the heater 36 included in the cold district specification unit 35, the power supply is controlled by the outside air temperature. Is characterized by. That is, FIG. 10 shows a power supply circuit (see FIG. 7).
The terminal portion of the power supply path (indicated by reference numeral 40 for convenience) from the heater to the heater 30 and the heater 36 is shown.
The terminal of branch code 41 is the connector 42,
It is connectable via 42 '. Branch code 41
Is connectable to a connector 41A for heating heaters, which can be connected to a connector on the side of the heating heater 30 (denoted by reference numeral 30A for convenience) at the branched power supply path terminal portion, and a connector 35A provided in the cold region specification unit 35. Each has a heater connector 41B. On the other hand, the power supply path 40 is provided with an outside air temperature detection control means 43 including a thermostat that can be turned on and off depending on the outside air temperature.
The outside air temperature detection control means 43 is connected with the heater heater 30 and the cold district specification unit 35 according to the outside air temperature after the power switch 13 (see FIGS. 1 and 7) of the garbage processing device is turned on. In this case, energization of at least one of the heaters 36 is controlled. Usually, when the garbage is put into the reaction tank 22, the garbage processing device requires a certain amount of time until the aerobic fermentation decomposition is completed. For this reason, in the present embodiment, by providing the outside air temperature detection control means 43, the management by the user during the processing time becomes unnecessary. That is, when the outside air temperature is a temperature at which the aerobic fermentation decomposition can be promoted at the time when the power switch 13 is turned on, the power supply in the device itself is stopped to reduce the running cost, and the outside air temperature is low. If it is a temperature at which the problem occurs, the cold region specification unit 35 is energized to prompt the drive control of the heater 36. When the cold region specification unit 35 is not connected, the energization control for the heater 30 is performed with reference to the outside air temperature. That is, when the outside air temperature is equal to or higher than the predetermined temperature, the heater 30
Is cut off. According to the embodiment as described above,
When the temperature in the reaction tank 22 is a temperature at which aerobic fermentation decomposition is favorably carried out, it is possible to positively stop the energization of the heater 30 to reduce the running cost.
Moreover, since such management can be performed by the device itself, it becomes possible to reduce the management burden on the user.

Next, another embodiment of the present invention will be described with reference to FIG.
Will be described. In the embodiment shown in FIG. 11, the heater 3 is used.
It is characterized in that the 0 and the heater 36 are controlled to supply power under their own temperature conditions. In FIG. 11, the same components as those shown in FIG. 10 are designated by the same reference numerals. In FIG. 11, a power supply circuit to the heater 30 and the heater 36 in the branch cord 41 is provided with an outside air temperature detection control member 5 composed of a thermostat.
0 and 51 are arranged respectively. The outside air temperature detection control members 50 and 51 are adapted to be energized when the heating heater 30 side has an outside air temperature at which the aerobic fermentation and decomposition cannot be performed, as an energization condition for the heating heater 30 and the heater 36. Therefore, when the heater 36 side has an outside air temperature at which dew condensation of evaporated moisture occurs, in other words, when the temperature is not higher than a predetermined temperature lower than the temperature at which aerobic fermentation and decomposition can be performed, power is supplied. As a matter of course, the outside air temperature detection control members 50 and 51 include the heater 30 and the heater 36.
The predetermined temperature is also different due to the difference in the function of, and the predetermined temperature on the heater 30 side is set to a value higher than the temperature on the heater 36 side. Since the present embodiment is configured as described above, in the power supply circuit on the heater 30 side, when the outside air temperature is equal to or higher than the temperature at which aerobic fermentation and decomposition can be performed, energization to the heater 30 is stopped. . Further, when the outside air temperature is a temperature corresponding to the condensation generation temperature in the reaction tank, the heater 36 is energized via the outside air temperature detection control member 50. According to this embodiment, the heating heater 30 and the heater 36 can be energized and controlled under their own temperature conditions. This makes it possible to maintain a state in which aerobic fermentation decomposition can be promoted and prevent the energy efficiency from decreasing due to the occurrence of dew condensation.

[0036]

As is apparent from the above embodiments, according to the first and second aspects of the present invention, when the outside air temperature detected by the temperature detecting means is below the predetermined temperature,
By energizing the heater that heats the space in the reaction tank and the surface of the processed product, it is possible to suppress the condensation of the water vapor evaporated from the processed product and discharge it. There is nothing to do. As a result, it is possible to prevent the evaporation water removal capacity from decreasing due to the outside air temperature, so that it is possible to prevent the efficiency of the energy used for evaporation of water from decreasing and to promote the aerobic fermentation. It is possible to improve the quality and prevent the generation of bad odor.

According to the third aspect of the invention, since the heater and the temperature detecting means can be retrofitted in addition to the heating means and the stirring means which are preliminarily installed in the reaction tank, it can be installed in a cold region. In order to prevent the deterioration of the water removing ability of the above, it can be equipped only by adding the constitution to the apparatus of the standard specification provided with the heating means and the stirring means. As a result, it is possible to change the specifications to those for cold climates as needed just by manufacturing standard specifications, so it is possible to prevent the production line costs from increasing and to dispose of waste in cold climates. You can enable it.

According to the fourth aspect of the present invention, the outside air temperature detection control means automatically controls the energization of at least one of the heater and the heating source according to the outside air temperature until the garbage processing is completed. After the power switch is turned on, the temperature control in the reaction tank and the water control in the cold district can be automatically executed by the device itself without depending on the user's control. . This simplifies the management while the raw garbage is being decomposed and reduces the management burden on the user.

According to the fifth aspect of the present invention, the heater for heating the reaction tank space and the surface of the processed material in the upper space of the reaction tank, and the temperature for maintaining the raw garbage processing in the reaction tank are maintained. Electric power supply to the heater and the heating source is controlled under their own temperature management by the outside air temperature detection control members provided in the power supply circuit for the heating source. This makes it possible for the device itself to automatically manage the control when heating or heating is required and when it is not required.
