DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposal apparatus having a moisture sensor for detecting a water content based on an output voltage.

[0002]

2. Description of the Related Art Conventionally, a garbage disposal tank of a garbage disposal apparatus is provided with a moisture sensor for detecting a water content.

[0003] That is, electrode plates are attached to the left and right side walls of the garbage disposal tank so as to face each other, and the voltage value between the electrode plates is used as a criterion for determining the water content of the processed material. By controlling a heater stretched on the outer surface of the arc-shaped bottom wall of the garbage processing tank to control the heating temperature of the processed material, the garbage is properly dried.

[0004]

That is, the water content decreases as the processing time elapses, and the reduced water content is detected based on a change in the voltage value by the moisture sensor. As described above, a constant voltage is applied to the moisture sensor, and the moisture content is detected from a function of the correlation between the voltage value and the moisture content by a change in the voltage value between the electrode plates.

However, in a moisture sensor that detects the moisture content based on the voltage value, the threshold value of the moisture sensor changes depending on the elapsed time of the process. That is, the correlation between the output voltage applied between the electrode plates of the moisture sensor and the water content changes with the progress of the process.

Therefore, it is detected that the water content detected at a constant output voltage in the early stage of the process and that the output voltage is lowered and the water content is lowered at the stage when the process is completed. Since the correlation with changes with the progress of the processing, when the water content is detected by the function of the conventional correlation at the output voltage at the end of the processing, a water content larger than the original correct water content is obtained. Will show.

As described above, the conventional detection of the water content is always performed by using a fixed function of the correlation between the output voltage and the water content. It was impossible to detect.

[0008]

A garbage disposal apparatus characterized in that the function of the correlation between the output voltage and the moisture content is changed along with the elapsed time of the garbage treatment, and the moisture content is detected from the output voltage by a function that matches the elapsed time of the treatment. Is to be provided.

[0009] In addition, the number of reset operations performed when adding sub-materials to the processed material is counted to obtain the processing elapsed time,
It is also characterized in that the function of the correlation between the output voltage and the water content is changed.

Another characteristic is that the all-reset operation is performed when the garbage is replaced, and the function of the correlation between the output voltage and the water content is returned to the initial state.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, garbage is put into a garbage disposal tank and stirred while the garbage is being processed.
Fermentation treatment is performed by adding a fermentation aid such as bacteria as necessary.

The detection of the water content of garbage is performed by applying a voltage between the electrode plates on the left and right side walls constituting the moisture sensor, and using the detected value of the output voltage as a function representing the correlation with the water content of water. Then, the water content is converted to the water content and the water content is detected.

In order to detect the water content, a function of the correlation between the output voltage and the water content that matches the processing elapsed time is used. Therefore, the optimum output voltage and the water content are determined in accordance with the garbage disposal progress. Accurate water content can be detected using the correlation function, and heater and fan can be operated based on the accurate water content to enable accurate heating control and humidity control, contributing to more efficient garbage disposal. You can do it.

The function is changed to a function of the correlation between the output voltage and the water content, and an accurate water content is obtained using the changed correlation.

Further, by performing the all-reset operation when replacing the garbage, the correlation between the output voltage and the water content is returned to the initial state, and the function of the correlation according to the progress of the garbage processing is changed. It is used to detect the water content accurately.

In the figure, 68 is a handle, 69 is a discharge switch, and the discharge switch 69 is connected to the control device 30.

When the shutter 67 is pulled forward, the garbage disposal tank 39 and the collection tray 62 communicate with each other, and the final residue after fermentation and aging treatment in the garbage disposal tank 39 is collected at once. It is to be discharged to 62.

As shown in FIGS. 1 to 4, the deodorizing section 5 has an exhaust means 70 for discharging the air inside the garbage disposal tank 39 to the outside, and a deodorizing means for deodorizing the odor generated from the garbage. And deodorizing means 71.

At this time, due to the action of the exhaust gas flowing inside the exhaust pipe 75, the pressure inside the exhaust pipe 75 becomes higher than the external pressure, and a negative pressure is generated in the external air suction hole 78, whereby External air is drawn into the exhaust pipe 75 from the external air suction hole 78.

Thus, by mixing the air with the odor inside the garbage disposal tank 39 flowing inside the exhaust pipe 75 and the air outside the exhaust pipe 75, the odor is diluted by the external air. The odor of the exhaust gas discharged from the exhaust pipe 75 can be reduced.

The garbage disposal apparatus 1 configured as described above
The feature of the present embodiment is that the moisture sensor 85 for detecting the moisture content from the output voltage based on the function derived from the correlation between the output voltage and the moisture content is a garbage disposal. The function of the correlation between the output voltage and the water content is changed along with the elapsed time of, and a function matching the processing elapsed time is selected to detect the water content from the output voltage.

Further, the number of reset operations performed when adding sub-materials to the processed material is counted, and the elapsed processing time is obtained from this count, and any one of the functions of the correlation between the output voltage and the water content is determined. There is also a feature in that it is configured to select, and when replacing garbage, perform an all reset operation to return the function of the correlation between the output voltage and the water content to the initial state. There are features.

That is, the moisture content is detected by converting the output voltage detected by the moisture sensor 85 by a function representing the correlation with the moisture content, and represents the correlation between the output voltage and the moisture content. As a function, as shown in FIG. 7, a function graph of a is used from a processing start date of garbage to a certain period (for example, 0 to 1 month), and a function graph of b is used for the next certain period (for example, 1 to 3 months). When the graph is used and the processing is further continued (that is, after three months), the function graph of c is used.

That is, the present inventor has noticed that the composition of the garbage changes with the lapse of the garbage disposal time, and the correlation between the output voltage and the water content changes every moment. The output voltage is converted into a water content by using the obtained correlation function.

Therefore, when the moisture content of the elapsed time of 1 to 3 months is calculated, if the moisture content is converted by using the correlation function a of 0 to 1 month uniformly, the same output is obtained. At the voltage detection value V1, the water content is the water content S1 of the actual garbage.
It is converted to a higher moisture content S2.

That is, in the case of using the correlation function b having an elapsed time of 1 to 3 months and the case of using the correlation function a having an elapsed time of 0 to 1 month, the detection value V1 of the same output voltage is used. Even if the water content is converted, the water content is different, and the water content S1 obtained by the function b of the correlation of the elapsed time of 1 to 3 months is smaller, and the water content is the highest in the processing garbage processing time of 1 to 3 months. A matched correct moisture content can be determined.

As described above, by obtaining the correct water content, various controls based on the water content are performed, and proper processing of garbage becomes possible.

That is, based on the correct water content, the temperature of the heater 46, the air volume of the suction fan 72, the operation pattern of the stirring claw shaft 54, and the like are controlled, and the water content of the garbage composition in the actual garbage disposal state is controlled. Processing control most suitable for the rate can be performed.

When a sub-material is added periodically (for example, every month), the reset switch 79 provided on the operation panel 29 is pressed, and the number of times the reset switch 79 is pressed is automatically counted. To determine the processing elapsed time,
The function of the correlation that changes with the processing elapsed time is selected from any of the function graphs a, b, and c.

That is, the time lag of the reset operation is set to 1
If it is set for each month, it is possible to know the processing elapsed month by counting the reset operation, and select one of the function graphs a, b, and c corresponding to the elapsed month.
The correct moisture content can be detected automatically.

Further, when the garbage is replaced, the all-reset switch 80 for replacing the garbage disposed on the operation panel 29 can be operated. If the all-reset operation is performed at the time, the function of the correlation between the output voltage and the water content returns to the initial state regardless of the garbage processing elapsed time until then.

That is, a new initial garbage disposal state was created by the replacement with the new garbage input, so that the function of the correlation with the output voltage for detecting the water content matched the garbage disposal state. The initial state, that is, the state of the function graph a in FIG. 7 is automatically returned by the all-reset operation, so that the operation of detecting the water content can be easily performed.

The all-reset operation can be performed manually by operating the switch 80. However, the all-reset operation is automatically performed based on a signal of the opening / closing operation of the input lid 26 performed when fresh garbage is input. It can also be configured.

The feature of this embodiment is that the pitch t of the driven sprocket 83 is increased to twice the pitch t of the conventional sprocket. That is, as shown in FIG. 8, the pitch t of the driving sprocket 57 is the width that the teeth 86 of the transmission chain 58 mesh one by one, whereas the pitch t of the large-diameter driven sprocket 83 is the tooth 86 of the transmission chain 58. Have a width that engages two by two.

Accordingly, although the diameter of the driven sprocket 83 is the same as that of the conventional sprocket, the number of teeth is half that of the conventional sprocket, so that the frequency of the driven sprocket 83 and the transmission chain 58 meshing with each other is also halved, and the noise generated at the time of meshing is reduced. The weight can be reduced, and the weight of the driven sprocket 83 can be reduced, so that the cost can be reduced.

Since the winding of the transmission chain 58 is sufficiently large, even if the pitch t of the driven sprocket 83 is twice as large as that of the conventional sprocket 83, no trouble such as the detachment or jump of the transmission chain 58 occurs.

Another feature of the present embodiment is that the leading edge of the shutter 67 is inclined as shown in FIG.

That is, when the shutter 67 is pulled forward, the garbage processing tank 39 and the collection tray 62 communicate with each other, and the residue in the garbage processing tank 39 is discharged to the collection tray 62. In order to return to the original position, the lower discharge tray 62 is discharged from the lower collection tray 62 to the bottom discharge port of the upper garbage disposal tank 39.
The garbage residue deposited at 84 must be pushed back by cutting off at the tip of the shutter 67.
Therefore, the tip of the shutter 67 is inclined in the width direction so that the inclined portion 87 makes it easier to cut off the residue.

Therefore, it is possible to eliminate the difficulty in closing the shutter 67, and it is possible to save the operation when closing the shutter 67 once opened.

Another feature of this embodiment is that a separate scraping claw 88 is provided at the tip of the stirring claw 60.

As shown in FIG. 10, similar to the stirring claw 60, the scraping claw 88 has a mounting portion 89 bent at a substantially right angle at the center.
And a plate-shaped tongue piece 90 connected at a right angle to the upper end of one of the two pieces forming the mounting portion 89 in a substantially right angle. By inserting the screw 93 into the hole 91 and the screw hole 92 provided at the upper end of the stirring claw 60,
A scraping claw 88 is attached to the tip of the stirring claw 60.

In particular, for the mounting portion 89 having a substantially right-angle cross section,
The side edge of the tongue piece 90 of the scraping nail 88 is a garbage disposal tank.
It is attached in the direction of sliding on the 39 arc-shaped bottom wall 45. The scraping claw 88 is attached to the tip of the stirring claw 60 of the stirring claw 60 which is closer to the left and right side walls 41, 42 of the garbage disposal tank 39. In particular, the scraping claw 88 has an arc-shaped bottom wall.
It is arranged so that corners can be scraped along the 45 side walls.

Therefore, it is possible to stir the bottom surface of the garbage disposal tank 39 to which the stirring claw 60 has not reached before, especially the junction corner and the peripheral surface with the left and right side walls 41 and 42, and such a stirring claw can be used.
The garbage can be prevented from sticking to parts that cannot be reached with 60.

The garbage processing apparatus 1 is configured as described above, and performs garbage processing as follows.

First, when the power is turned on, the operation panel 29 is turned on.
The power LED provided on the LED lights up, and the control device 30 starts operating.

After the power is turned on, when the proximity switch 82 detects that the closing lid 26 has been opened and closed, that is, it is determined that the closing lid 26 has changed from the “closed state” to the “open state” and has again changed to the “closed state”. When it is detected, or when an all-reset operation for detecting the moisture content is performed, it is determined that fresh garbage has been introduced into the fresh garbage treatment tank 39, and the output voltage and the moisture content are determined. The function of the correlation has been returned to the initial state. Based on the function, the moisture content is converted and detected from the output voltage, and the fermentation / ripening control of the control device 30 is performed.

The controller 30 controls the heater in accordance with the water content inside the garbage disposal tank 39 detected by the moisture sensor 85.
The temperature of 46, the air volume of the suction fan 72, and the operation pattern of the stirring claw shaft 54 are appropriately controlled.

That is, when the moisture content of the processed garbage detected by the moisture sensor 85 is within a predetermined range, the garbage is set to an appropriate state, when it is below the predetermined range, it is in a dry state, and when it is above, it is in an over-moisture state. Therefore, the temperature of the heater 46 is set to be higher than usual in the over-moisture state.

In the dry state, the suction fan 72 is operated with a smaller air flow than usual.

Further, the rotation of the stirring pawl shaft 54 is performed in the cycle of reverse rotation, short-term stop, normal rotation, and long-term stop. The higher the water content, the shorter the long-term stop period, and the shorter the cycle. The rotation is performed. That is, on the basis of the appropriate state, the stirring claw shaft 54 is rotated at a shorter cycle in the over-moisture state and at a longer cycle in the dry state.

The detection of the water content for performing such control is detected based on a function derived from the correlation between the output voltage and the water content. For example, as shown in FIG. Explaining the function graphs a, b, and c, if within one month from the fresh addition of garbage, based on the function graph of the correlation between the output voltage and the water content indicated by a in the function graph, The moisture content is converted and detected.

However, when the processing elapsed time of one month or more and three months or less has elapsed, the water content is converted based on the graph of the correlation function shown by b in the function graph shown in FIG. When the elapsed time is three months or more, the moisture content is converted and detected by a function graph shown by c in the function graph shown in FIG.

As described above, the water content is determined by the processing state of the garbage,
That is, since it is configured to accurately detect and perform various controls by a function of the correlation between the output voltage and the water content corresponding to the composition change due to the processing of the garbage, The most appropriate moisture content can be detected, and the operations of the heater 46, the suction fan 72, and the stirring claw shaft 54 can be controlled accordingly.

When replacing old garbage with new garbage, an all-reset operation is performed at the time of detecting the water content, and the function of the correlation between the output voltage and the water content is returned to the initial state. In addition, the input of new garbage, the all-reset operation by replacement, especially provided with an all-reset switch 80, when the operation of this switch 80, and a detection mechanism that automatically detects the replacement of new garbage, For example, there is a case where the input and replacement of new garbage can be automatically detected by the opening and closing operation of the input lid 26. However, it is necessary to separately provide a new garbage input detection mechanism in order to distinguish the operation from the opening / closing operation of the input lid 26 due to the input of a sub-material such as a fermentation aid described later.

As described above, when supplementary materials such as a fermentation aid and a deodorant are additionally introduced into the processed garbage during the processing of the garbage, the reset operation must be performed at the time of the adding operation. It is performed manually or automatically at the same time, and the time lag of inputting the sub-material is set about every one month or every certain time.

By automatically counting the number of reset operations at the time of inputting the auxiliary material, the elapsed processing time is automatically determined. For example, if the number of reset operations is counted every month, the number of reset operations is counted every month. The function of the correlation between the output voltage and the water content according to the process can be automatically selected,
The correct moisture content can be known from the detected value of the output voltage.

In this way, by using the function of the correlation between the output voltage and the water content that matches the constantly changing garbage disposal situation, it is possible to correctly detect the water content and perform various processing controls.

When the fermentation and aging treatments are completed, the processed material is discharged from the garbage disposal tank 39 to the collection tray 62 for collection. At this time, the garbage disposal tank 39 and the collection tray 62 are collected.
When the shutter 67 of the shutter mechanism 64 interposed between the shutter 67 and the shutter 67 is opened and the shutter 67 is closed again after performing the discharging operation, the inclined portion 87 formed at the leading edge of the shutter 67 cuts off the workpiece. This can be easily performed, the shutter 67 can be easily closed, and the garbage collection operation can be easily performed.

[0092]

According to the first aspect of the present invention, the correlation between the output voltage and the water content is changed for each elapsed time of the garbage processing to detect the water content of the garbage. Although the moisture content is detected from the output voltage by the function of the unified correlation, the accurate moisture content can be obtained by using the function of the correlation that changes with the progress of the garbage disposal, and the heating control can be performed. There is an effect that the drying can be performed accurately and the drying process can be performed efficiently.

According to the second aspect of the present invention, the reset operation at the time of adding the auxiliary material can be counted to obtain the processing elapsed time and the function of the correlation can be changed. There is an effect that can be obtained.

According to the third aspect of the present invention, since the correlation function is returned to the initial state by the all-reset operation at the time of replacing the garbage, it is possible to always use the correlation that matches the progress of the processing, and to obtain accurate water content. This has the effect that the rate can be detected and the drying and heating treatment can be performed efficiently.
