Abstract

PROBLEM TO BE SOLVED: To maintain the same temperature as that during ordinary operation of each part even when a temperature rise process is repeated by providing a control means to decide operation of a cooling fan based on the input from a temperature sensor at the initial stage or during the starting of disposal after suspension of the disposal. SOLUTION: A control means 29 performs decision of the initial temperature according to temperature information from a temperature sensor 26. When temperature information is below 100 deg.C, it is decided that the temperature of a dry heater 28 is prevented from sufficient rise, and at a preliminary heating process, a cooling fan 25 is brought into an OFF-state and control is effected such that the temperatures of a drying heater 23 and a catalyst heater 28 rise rapidly. When it exceeds 100 deg.C, after suspension of disposal, it is decided that temperature inside the body 21 sufficiently rises, and a cooling fan 25 is turned on from the initial stage even when the body is in a preliminary heating process, the cooling fan 25 is turned on and operation is effected such that cooling of the interior of the body 21 is performed. Thus, even when disposing is not suspended, even at re-disposal after suspension, optimum cooling corresponding to the situation is made on the interior of the body 21.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposer for treating garbage such as garbage.

[0002]

2. Description of the Related Art A conventional kitchen waste disposal machine will be described with reference to FIG. In the figure, 1 is a kitchen waste treatment machine main body,
Reference numeral 2 denotes a kitchen waste container, reference numeral 3 denotes a drying heater for heating and drying the kitchen waste, reference numeral 4 denotes a stirring blade provided in the processing container 2 for stirring the kitchen waste, and reference numeral 5 denotes cooling of the inside of the main body 1. 6 is a temperature sensor for detecting the temperature of the garbage by replacing it with the ambient temperature. 7 is a catalyst for deodorizing odors generated from the garbage in the processing container 2 in the process of processing the garbage. And a catalyst heater 8 for heating a gas having the following.

Reference numeral 9 denotes control means for controlling the operation of the drying heater 3 and the operations of the stirring blade 4 and the cooling fan 5 based on temperature information input from the temperature sensor 6.
Denotes a lid of the main body 1, 12 denotes a power supply for supplying power to all, and 11 denotes a lid SW for stopping the power supply from the power supply 12 when the lid 10 is opened.

[0004] In the above configuration, when the process is started, under the control of the control means 9, as a preheating step,
The drying heater 3 is operated to raise the temperature of the garbage to a target temperature. In the subsequent processing steps, the garbage in the processing container 2 is heated by the drying heater 3 and the stirring blades 4 are used.
Starts its operation, and is agitated by its rotation to promote drying and pulverization. At this time, the operation of the drying heater 3 is controlled based on the temperature information of the temperature sensor 6 so that the drying heater 3 is turned on when the temperature is lower than a preset temperature, and is turned off when the temperature is higher than the preset temperature, and the process of the process is shifted.

Further, the control means 9 does not operate the cooling fan 5 in the preheating step at the start of the processing, and in the subsequent processing steps, the heat of the drying heater 3 is generated not only in the kitchen waste but also in the main body 1. In order to heat the various parts, the cooling fan 5 is operated to cool the main body 1 and the inside. During the treatment, the odor generated from the garbage is deodorized by passing through the catalyst 7 and being heated and oxidized by the catalyst heater 8. If the lid 10 is opened during the processing, the lid SW11 is turned off in consideration of safety, the power supply from the power supply 12 is stopped, and the processing is interrupted.

【Example】

(Embodiment 1) Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.

In FIG. 1, reference numeral 21 denotes a kitchen waste processing machine main body, reference numeral 22 denotes a kitchen waste processing container, reference numeral 23 denotes a drying heater for heating and drying the kitchen waste, and reference numeral 24 denotes a kitchen waste provided in the processing container 22. 25 is a cooling fan for cooling the inside of the main body 21, 26 is a temperature sensor for detecting the temperature of the garbage by replacing it with the ambient temperature, and 27 is a processing container in the process of processing the garbage. The catalyst 22 is a catalyst for deodorizing odors generated from kitchen waste and has a catalyst heater 28 for heating odorous gas.

Reference numeral 29 denotes control means for controlling the heating temperature of the drying heater 23 and controlling the operations of the stirring blade 24 and the cooling fan 25 based on the temperature information input from the temperature sensor 26.

The operation of the above configuration is as follows.
When the power is turned on and the processing is started, the control means 29
Each load is controlled in the preheating step shown in the step transition diagram of FIG. 2, the drying heater 23 is turned on, and the temperature sensor 26 is turned on.
Is started until the temperature information input from the device reaches the target temperature, for example, 130 ° C. When the power is turned on, the catalyst 27
The catalyst heater 28 is energized, the temperature rises in the preheating step, and preparations are made to deodorize the odor generated by heating, stirring and pulverizing the garbage. For this reason,
In the preheating step, the stirring blade 24 is not operated because the catalyst 27 is not in a state where the catalyst 27 can sufficiently exhibit its deodorizing performance.

As shown in FIG. 2, the control means 29 makes an initial temperature judgment based on the temperature information input from the temperature sensor 26 at the start of the process when the power is turned on, that is, at the beginning of the preheating step. If the temperature information is lower than 100 ° C., this is the first processing after the kitchen waste is put into the processing container 22. At this time, it is determined that the temperatures of the drying heater 23 and the catalyst heater 28 have not sufficiently risen, and the preliminary heating step is performed. In, the cooling fan 25 is turned off, and control is performed so that the temperatures of the drying heater 23 and the catalyst heater 28 rise quickly. If the temperature information is 100 ° C. or more, the power is re-input due to the interruption of the processing for the purpose of adding additional garbage,
When it is determined that the temperature in the main body 21 including the drying heater 23 and the catalyst heater 28 has sufficiently risen, the cooling fan 25 is turned on from the beginning even in the preheating step to operate to cool the main body 21. .

After the temperatures of the drying heater 23 and the catalyst heater 28 have sufficiently risen, the control means 29 shifts the control of each load to a pulverizing and drying step, and controls the temperature of the drying heater 23. As shown in FIG. 2, the temperature adjustment control operates such that the drying heater 23 is turned off when the temperature information input from the temperature sensor 26 becomes higher than the target temperature (130 ° C.), and turned on when the temperature information becomes lower. At this time, the temperature sensor 26 causes an overshoot of the temperature even after the drying heater 23 is turned off or on due to the influence of the distance from the drying heater 23 and peripheral components. That you are doing.

As for the cooling fan 25, the drying heater 2
3 and the temperature of the catalyst heater 28 have risen sufficiently, so that they are always on, and the stirring blades 24 are turned on for 1 second and off for 11 seconds 25 times in order to promote the crushing and drying of the garbage under optimal conditions. After that, the reversal is performed in the same manner, and this is repeated.

When the crushing / drying process is completed, the control means 2
9 shifts the control of each load to the cooling step,
3 is always turned off, the cooling fan 25 is operated while the stirring blades 24 are operated, the kitchen and the main body 21 and the inside of the main body 21 are cooled, and the process is completed.

Thus, the main body 21 and the drying heater 2 can be operated regardless of whether the processing is interrupted or when the processing is interrupted.
3. Optimum cooling according to the situation can be performed without the temperature inside the main body 21 including the periphery of the catalyst heater 28 rising excessively.

(Embodiment 2) Next, a second embodiment of the present invention will be described with reference to FIGS.

In FIG. 4, reference numeral 21 denotes a kitchen waste processing machine main body, reference numeral 22 denotes a kitchen waste processing container, reference numeral 23 denotes a drying heater, reference numeral 24 denotes a stirring blade, reference numeral 25 denotes a cooling fan, and reference numeral 26 denotes a temperature sensor. 27 is a catalyst heater 28
It is a catalyst that has odor and deodorizes odors generated from kitchen waste.
The above is the same configuration as the first embodiment.

The difference from the first embodiment is that the control means 50
Is configured to determine the operation of the stirring blade 24 based on the temperature information input from the temperature sensor 26 at the start of the process.

The operation of the above configuration is as follows.
As shown in FIG. 5, at the start of the process when the power is turned on, that is, at the beginning of the preheating step, the control unit 50 performs the initial temperature determination based on the temperature information input from the temperature sensor 26. If the temperature information is lower than 100 ° C., this is the first processing after the kitchen waste is put into the processing container 22. At this time, it is determined that the temperatures of the drying heater 23 and the catalyst heater 28 have not sufficiently risen, and the preliminary heating step is performed. In the above, the stirring blades 24 are always turned off, so that odor is not generated from the garbage by stirring, and if the temperature is 100 ° C. or more, the power is re-input by interrupting the processing for the purpose of adding the garbage, It is determined that the temperature in the main body 21 including the drying heater 23 and the catalyst heater 28 has sufficiently risen, and the stirring blade 24 is operated from the beginning even in the preheating step,
It operates so that grinding and drying are further promoted.

After the pulverizing and drying step, the same operation as in the first embodiment is performed. Accordingly, when the temperatures of the drying heater 23 and the catalyst heater 28 are not rising, the crushing and drying are performed immediately when the temperature is rising so that the odor does not appear, and the optimal stirring operation according to the situation can be performed. it can.

(Embodiment 3) A third embodiment of the present invention will be described with reference to FIGS. 6, 7, and 8. FIG.

In FIG. 6, reference numeral 61 denotes a kitchen waste processing machine main body, 62 denotes a kitchen waste processing container, 63 denotes a drying heater for heating and drying the kitchen waste, and 64 denotes a kitchen waste provided in the processing container 62. A stirring blade for stirring, a cooling fan 65 for cooling the inside of the main body 61, a temperature sensor 66 for detecting the temperature of the kitchen garbage by replacing it with the ambient temperature, and a processing container 67 in the process of processing the kitchen garbage The catalyst 62 is a catalyst for deodorizing odors generated from the kitchen waste and has a catalyst heater 68 for heating gas having an odor.

Numeral 70 denotes a timer for starting time measurement in accordance with an instruction from the controller 69 and outputting the measured time to the controller 69. 69 is provided to the timer 70 based on temperature information input from the temperature sensor 66. Control means for instructing measurement and controlling the temperature by the drying heater 63 and the operation of the stirring blade 64 and the cooling fan 65 based on the input measurement time.

The operation of the above configuration is as follows.
When the power is turned on and the processing is started, the control means 69
The loads in the preheating step shown in the step transition diagram of FIG. 7 are controlled, and the drying heater 63 is turned on. At this time, the control means 69 sets 130 ° C. as the first target temperature, and starts up until the temperature information input from the temperature sensor 66 becomes 130 ° C. After the start of the process as shown at point a in FIG.
When the temperature information input from the temperature sensor 66 for the first time is 13
When the temperature exceeds 0 ° C., the control unit 69 outputs an instruction to the time counting unit 70 to start time measurement at the same time as turning off the drying heater 63. The timer 70 starts counting by inputting an instruction, and outputs the measured time to the controller 69.

After that, since the drying heater 63 is turned off, the temperature information input from the temperature sensor 66 is shown in FIG.
After the overshoot shown in FIG. The control means 69 makes an empty judgment by comparing the measurement time t (shown in FIG. 8) at this moment input from the time measurement means 70 with a preset time T.

The processing container 62 is made of metal or resin. Generally, kitchen waste contains a large amount of water, and therefore has a lower thermal conductivity than metal or resin. Time t is longer than when nothing is
Becomes longer.

The time T is set so that the above two states can be discriminated. If the control means 69 determines that T <t, it is determined that there is garbage in the processing container 62.
The control temperature of the drying heater 63 is set to the second target temperature of 150 ° C., which is the temperature for crushing and drying, and the temperature control of the drying heater 63 is performed in the crushing and drying step.

Further, as shown in FIG. 7, it is set so that the temperature control at 130 ° C. is performed in the latter half of the pulverizing and drying step. If T ≧ t, it is determined that the inside of the processing vessel 62 is empty. Then, after the empty judgment, the operation is performed from the latter step of 130 ° C. in the pulverization and drying step, and the processing is completed through the cooling step. At this time, the operation after the empty determination is performed in the middle of the crushing and drying step, because only a very small amount of garbage is contained, and the processing is performed even when it is determined that the empty is determined. .

Thus, the main body 61 and the main body 61 in the idling operation can be used without using the temperature sensor 66 for controlling the temperature adjustment of the drying heater 63 and adding an empty judgment sensor.
The inside can be protected from the influence of heat.

(Embodiment 4) A fourth embodiment of the present invention will be described with reference to FIGS. 7, 8 and 9. FIG.

Reference numeral 61 denotes a kitchen waste processing machine main body, 62 denotes a kitchen waste processing container, 63 denotes a drying heater, 64 denotes a stirring blade, 65 denotes a cooling fan, 66 denotes a temperature sensor, and 67 denotes a temperature sensor. Is a catalyst having a catalyst heater 68 for deodorizing odor generated from kitchen waste, and 70 is a control means 9
Time counting means for starting time measurement in response to an instruction from 0 and outputting the measured time to the control means 90. The above configuration is the same as that of the third embodiment.

The difference from the third embodiment is that the control means 90
Is configured to determine whether or not to perform the empty determination based on the temperature information input from the temperature sensor 66 at the start of the process.

The operation of the above configuration is as follows.
As shown in FIG. 7, at the start of the process when the power is turned on, that is, at the beginning of the preheating step, the control means 90 makes an initial temperature determination based on the temperature information input from the temperature sensor 66. If the temperature information is lower than 100 ° C., this is the first process. At this time, there is a possibility that the inside of the processing container 62 is empty, and the empty determination shown in the third embodiment is performed.

The determination time T of the empty determination is the first target temperature 13
The time is set at the time between the off and on of the drying heater 63 at 0 ° C. When the process is temporarily interrupted during the temperature control at 150 ° C. in the pulverizing and drying step, and the process is started again, FIG. The measurement time t shown in the figure becomes a value including an error.

Therefore, if the temperature information is 100 ° C. or higher, it means that the power supply has been turned on again due to the interruption of the processing for the purpose of adding additional garbage, and it has been confirmed that the garbage has been loaded into the processing container 62. The first target temperature is also set to 150 ° C., and the operation is performed to promote drying.

This eliminates erroneous determination of the empty judgment due to the power being turned on again, thereby improving the accuracy of the empty judgment.
