[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cocoon treatment apparatus for drying cocoons such as garbage.
[0002]
[Prior art]
Conventionally, this type of soot treating apparatus has been configured as shown in FIG. Hereinafter, the configuration will be described.
[0003]
As shown in the figure, the garbage storage container 1 is used to put a basket such as the garbage 20 to be dried, and is provided with a stirring blade 7 driven by a drive motor 8 so as to be rotatable. The 1st heating means 2 is comprised with a sheathed heater etc., and heats the outer bottom face of the garbage storage container 1. FIG. The lower temperature detection means 3 is disposed on the bottom rear surface of the garbage storage container 1 and detects the temperature of the bottom surface of the garbage storage container 1. The first heating means 2 is controlled to be heated at a predetermined temperature by the heating control means 6 based on the output of the lower temperature detecting means 3.
[0004]
In the upper part of the garbage storage container 1, the second heating means 15 constituting the hot air generating and stirring means 14, the blower means 16 for sending the heat of the second heating means 15 into the interior of the garbage storage container 1, and the outside air An air intake unit 10 for inflow, an exhaust unit 11 for discharging gas containing water vapor generated from the garbage 20, and an upper temperature detection means 4 for detecting the temperature of the garbage storage container 1 during processing are provided. Are provided with a catalyst 12 for removing the odor contained in the gas and a catalyst heating means 13.
[0005]
The operation of the above configuration will be described with reference to FIG. First, the catalyst heating means 13 is heated for a predetermined period to raise the temperature of the catalyst 12 and improve the catalyst function. Next, the first heating means 2 and the second heating means 15 are turned on. The garbage 20 thrown into the garbage storage container 1 is heated by the first heating means 2 on the outer bottom surface of the garbage storage container 1 while being scraped up by the stirring blades 7, and the scraped garbage 20 is heated at the upper part. The two heating means 15 and the air blowing means 16 are heat-dried.
[0006]
After the start of operation, the first heating means 2 is heated at a predetermined temperature by the heating control means 6 based on the output of the lower temperature detection means 3 (temperature control), and the second heating means 15 is always turned on and heated. Then, the garbage 20 is heated and dried while being crushed by the stirring blade 7. As drying progresses, water vapor decreases and the temperature of the upper space rises rapidly.
[0007]
The temperature detected by the upper temperature detecting means 4 has a temperature characteristic as shown in FIG. 9. When this temperature reaches a predetermined value, it is determined that the drying is finished, and the first heating means 2 and the second heating means 15 are detected. Is turned off, and the blowing means 16 is turned on for a predetermined period to cool the apparatus.
[0008]
[Problems to be solved by the invention]
However, in such a conventional configuration, only the second heating means 15 for heating the upper part of the garbage storage container 1 prevents the temperature in the garbage storage container 1 from sufficiently rising, and the garbage storage container. The temperature inside 1 is adjusted by the first heating means 2 provided on the outer bottom surface of the garbage storage container 1.
[0009]
For this reason, the first heating means 2 for heating the lower part of the garbage storage container 1 needs to perform heating control (temperature control), and therefore, it is necessary to provide the lower temperature detection means 3. Only the lower temperature detection means 3 cannot quickly detect the ambient temperature of the upper part of the garbage storage container 1, and the temperature change at the end of drying is small. Therefore, depending on the temperature detected by the lower temperature detection means 3, It was difficult to determine the drying end time, and it was necessary to provide the upper temperature detection means 4.
[0010]
For this reason, it is necessary to provide temperature detection means on the upper and lower parts of the garbage storage container 1, respectively, which is inconvenient in terms of mounting workability and assembly.
[0011]
Further, the heating time and cooling time of the catalyst 12 in the drying process time and the previous process of the drying process are determined as the predetermined time. For this reason, when the drying time is set to a predetermined time, when the amount of garbage is small, it becomes overdried and burnt, and conversely, when the amount of garbage is large, it becomes undried and put into the garbage storage container 1 Depending on the amount of garbage produced, the drying state of the garbage differs greatly, or if the heating time of the catalyst 12 in the previous step of the drying process is determined as a predetermined time, the catalyst 12 can be heated sufficiently when the ambient temperature is low. If the blower means 16 is turned on and the blower means 16 is turned on, the odor is not sufficiently removed by the catalyst 12, or if the cooling time is set to a predetermined time, it is sufficiently cooled when the amount of garbage is large. there has been a problem that the ends without.
[0012]
The present invention solves the above-described conventional problems, and determines that the drying of the garbage has been completed and finishes the heating drying reliably, and improves the mounting workability and assembly of the heating means and the temperature detection means. The purpose is that.
[0013]
[Means for Solving the Problems]
In order to achieve the above object, the present invention is provided with a heating means and an air blowing means at the upper part in the garbage storage container to allow the outside air to flow in from the intake part and to discharge the steam generated from the garbage from the exhaust part, The temperature detection means is configured to detect the temperature in the garbage storage container, and the heating means includes a first heating means for adjusting temperature by an output of the temperature detection means and a second heating means for performing continuous operation, When the garbage in the garbage storage container is heated and dried together with the air blowing means, and the temperature detected by the temperature detection means exceeds a predetermined value, the first heating means is turned on and off to control the inside of the garbage storage container. In the state where the temperature of is kept at a predetermined temperature, the drying process proceeds and water vapor is reduced, the temperature in the garbage storage container detected by the temperature detection means rises, and the first heating means is turned off. Storage capacity The temperature of the inner rises, the output of the temperature detecting means becomes a second predetermined value or more, it is determined that termination time of the drying process, which is constituted so as to terminate the drying process.

【Example】
Embodiments of the present invention will be described below with reference to the drawings.
[0017]
(Example 1)
A first embodiment of the present invention will be described below with reference to FIGS. In addition, about the same part as a prior art example, the same code is attached and the description is abbreviate | omitted.
[0018]
In FIG. 1, the garbage storage container 1 has a stirring blade 7 driven by a drive motor 8 rotatably attached thereto. A first heating unit 22, a second heating unit 22 a, and a blower unit 16 including a sheathed heater are provided on the upper part of the garbage storage container 1. Air is taken into the garbage storage container 1 from the air inlet 10 and is sent into the garbage storage container 1 as hot air by the blowing means 16. The exhaust unit 11 is provided in a part of the garbage storage container 1 to release a gas containing water vapor generated from the garbage 20 and to remove the odor contained in the gas and a catalyst heating means for assisting the function of the catalyst. 13 is provided.
[0019]
The temperature detection means 23 is disposed on the upper surface of the garbage storage container 1 so as to detect the ambient temperature in the garbage storage container 1, and the first heating means 22 is based on the output of the temperature detection means 23. Thus, the heating control means 6 is configured to perform heating control (temperature adjustment) at a predetermined temperature. The second heating means 22a is always turned on and heated during the drying operation. For example, the first heating means 22 that is heated and controlled based on the output of the temperature detection means 23 is a 1600 W heater, and the second heating means 22 a that is always on is a 1200 W heater.
[0020]
The operation of the above configuration will be described with reference to FIG. The garbage 20 put into the garbage storage container 1 is heated and dried by the first heating means 22, the second heating means 22 a and the air blowing means 16 while being pulverized and stirred by the stirring blade 7. The stirring blades 7 are repeatedly turned on / off every predetermined time, and the garbage 20 is stirred by performing the operation while reversing the forward rotation / reverse rotation.
[0021]
When the temperature detected by the temperature detection means 23 exceeds a predetermined value, the first heating means 22 is turned off, and when the temperature detected by the temperature detection means 23 is less than the predetermined value, the first heating means 22 is turned on. Is the main operation of the drying process. When there is moisture in the garbage, the temperature in the garbage container 1 is kept at a predetermined temperature by the heating control of the first heating means 22 by the temperature detection means 23.
[0022]
When this drying process proceeds and the amount of water vapor decreases, the temperature in the garbage storage container 1 rises, and even if the first heating means 22 is turned off, the temperature of the upper space rapidly increases due to the heating by the second heating means 22a. When the temperature rises and the output of the temperature detecting means 23 becomes equal to or higher than the second predetermined value, it is determined that the drying is finished, and the drying processing step is finished.
[0023]
Thus, the temperature detection means 23 provided in the upper part in the garbage storage container 1 can detect that the moisture of the garbage has been lost, and can reliably finish heating and drying. Installation of the first heating means 22, the second heating means 22 a, and the temperature detection means 23 by providing the first heating means 22, the second heating means 22 a, and the temperature detection means 23 in the upper part of the container 1. And assembly can be improved.
[0024]
(Example 2)
Next, a second embodiment of the present invention will be described with reference to FIG. The same parts as those in the above embodiment are denoted by the same reference numerals, and the description thereof is omitted.
[0025]
In this embodiment, the catalyst heating means 13 is turned on before turning on the first heating means 22 and the second heating means 22a and the air blowing means 16, and only the catalyst heating means 13 is turned on when the temperature detecting means 23 is turned on. In the output, the first heating means 22, the second heating means 22a and the air blowing means 16 are turned on.
[0026]
The operation of the above configuration will be described with reference to FIG. Prior to starting the main heating by turning on the first heating means 22 and the second heating means 22a, the catalyst heating means 13 is turned on to ensure the function of the catalyst 12. When the catalyst heating unit 13 is turned on, the temperature detected by the temperature detection unit 23 increases little by little.
[0027]
Therefore, when the output of the temperature detection means 23 reaches a predetermined value regardless of the ambient temperature, it is determined that the catalyst 12 has been sufficiently heated, and the first heating means 22, the second heating means 22a, and the blower means 16 are turned on. Then, the drying process is started. If the output of the temperature detecting means 23 reaches a predetermined value from the beginning, the first heating means 22, the second heating means 22a, and the air blowing means 16 are immediately turned on, and the drying process is started.
[0028]
As described above, since the drying process is started at a temperature at which the function of the catalyst 12 can be sufficiently exerted, even if the air blowing means 16 is turned on, the malodor is sufficiently taken out by the catalyst 12, so that the malodor is not discharged.
[0029]
(Example 3)
Next, a third embodiment of the present invention will be described with reference to FIG. The same parts as those in the above embodiment are denoted by the same reference numerals, and the description thereof is omitted.
[0030]
In this embodiment, the heating control means 6 controls the first heating means 22 by changing the set value for turning on and off the first heating means 22 according to the maximum value of the output of the temperature detection means 23 for a predetermined period. It is configured to do.
[0031]
The operation of the above configuration will be described with reference to FIG. If the amount of garbage 20 put into the garbage storage container 1 is large, the amount of air in the upper space in the garbage storage container 1 is small, and the garbage 20 is likely to be warmed, and the output of the temperature detection means 23 varies. Becomes larger. Further, at the initial stage of the drying process, since the amount of water vapor is small, the temperature of the upper space is likely to be warmed, and the fluctuation of the output of the temperature detecting means 23 is similarly increased.
[0032]
Therefore, the set value for turning on / off the first heating means 22 is changed at the maximum value of the output of the temperature detecting means 23 for a predetermined period. For example, as shown by the thick line in FIG. 4, if the temperature is high, the set value for turning on / off the first heating means 22 is changed to a low value. Then, the maximum value of the fluctuation of the output of the temperature detecting means 23 also decreases, and the erroneous determination of the end of heating by the first heating means 22 and the second heating means 22a is eliminated by the value of the fluctuation of the output of the temperature detecting means 23. The heat drying can be completed.
[0033]
Therefore, the heating by the first heating means 22 and the second heating means 22a can be completed regardless of the amount of garbage that has been thrown in, and the heating and drying can be completed with certainty.
[0034]
Example 4
Next, a fourth embodiment of the present invention will be described with reference to FIG. The same parts as those in the above embodiment are denoted by the same reference numerals, and the description thereof is omitted.
[0035]
In the present embodiment, the rotation period of the stirring blade 7 by the drive motor 8 in the first embodiment is determined when the first heating means 22 is turned on according to the maximum value of the output of the temperature detecting means 23 in a predetermined period. It is something to change. Other configurations are the same as those in the above embodiment.
[0036]
The operation of the above configuration will be described with reference to FIG. If the amount of garbage 20 put into the garbage storage container 1 is large, the amount of air in the upper space in the garbage storage container 1 is small, and the garbage 20 is likely to be warmed, and the output of the temperature detection means 23 varies. Becomes larger. By changing the ON time of the operation of the stirring blade 7 at the maximum value of the output of the temperature detecting means 23 for a predetermined period, the degree of stirring is made to correspond to the amount of the garbage 20 that has been put in, and an appropriate drying process is performed. be able to.
[0037]
As shown by the thick line in FIG. 5, the temperature distribution in the garbage storage container 1 can be made more uniform by stirring for a long time if there is a large amount of garbage 20 and agitating for a short time if there is little food waste 20. The output of the detection means 23 is stabilized, and the end of the drying process is stabilized.
[0038]
Therefore, the heating by the first heating means 22 and the second heating means 22a can be completed regardless of the amount of garbage that has been thrown in, and the heating and drying can be completed with certainty. Moreover, by making the stirring of the garbage 20 uniform, there is also an effect of making the processing product of the garbage 20 uniform and improving the processing result.
[0039]
(Example 5)
Next, a fifth embodiment of the present invention will be described with reference to FIG. The same parts as those in the above embodiment are denoted by the same reference numerals, and the description thereof is omitted.
[0040]
In this embodiment, the heating control means 6 determines a set value for ending heating by the first heating means 22 and the second heating means 22a at the maximum value of the output of the temperature detection means 23 for a predetermined period, and heating Is to end. Other configurations are the same as those in the above embodiment.
[0041]
The operation of the above configuration will be described with reference to FIG. If the amount of garbage 20 put into the garbage storage container 1 is large, the amount of air in the upper space in the garbage storage container 1 is small, and the garbage 20 is likely to be warmed, and the output of the temperature detection means 23 varies. Becomes larger. In addition, since the amount of water vapor generated is small at the initial stage of the drying process, the temperature of the upper space is likely to be warmed, and similarly the fluctuation of the output of the temperature detecting means 23 becomes large.
[0042]
Therefore, the set value for the end of heating by the first heating means 22 and the second heating means 22a is determined by the maximum value of the output of the temperature detection means 23 for a predetermined period. For example, as shown by the thick line in FIG. 6, if the temperature is high, the set value of the end of heating by the first heating means 22 and the second heating means 22a is changed to be high. In the latter half of the drying process, water vapor is reduced, the temperature of the upper space rapidly rises, the output of the temperature detecting means 23 becomes equal to or higher than the set value, and it is determined that the drying is finished, and the drying process is finished.
[0043]
Therefore, the heating by the first heating means 22 and the second heating means 22a can be ended regardless of the amount of garbage put in, the heating and drying can be finished with certainty, and the drying process and drying more than necessary. It eliminates the premature termination of the process, and does not cause the burning of the garbage or the termination without being dried.
[0044]
(Example 6)
Next, a sixth embodiment of the present invention will be described with reference to FIG. The same parts as those in the above embodiment are denoted by the same reference numerals, and the description thereof is omitted.
[0045]

When the heating by the first heating unit 22 and the second heating unit 22a is completed and the first heating unit 22 and the second heating unit 22a are turned off, the temperature decreases. As shown by the thick line in FIG. 7, when the amount of garbage 20 that has been input is large, the temperature decrease is slow, and when the amount of garbage 20 is small, the temperature decrease is rapid. When the cooling period is set by the output of the temperature detecting means 23, the main body temperature is lowered at the end of the drying process regardless of the amount of the garbage 20 that has been input, and safety can be improved.
[0047]
